The terminal is under the hood on the right side of the fuse box, but it is only actually designed for an inbound jump to the Sienna. Jump starting another vehicle is not recommended because none of the Toyota Hybrids have a lot of 12V amps available (12V only boots the computers and runs accessories). Choose your battles wisely, then.

A 2021 Toyota Sienna’s battery can be found where?
Every Sienna made in 2021 is a gas-electric hybrid. Toyota positioned the 1.9-kWh nickel-metal-hydride battery under the front seats to keep the cargo space of the van low and level. The row of air vents located below the seat controls is a telling indicator. If you’re wondering why Chrysler chose not to implement a hybrid version of the Pacifica, it’s because the Sienna’s battery is inadequate. Due to its one-eighth capacity, it is unable to provide the plug-in setup’s range-extending EV performance.
The rear fenders’ fins, which are polished black, are a reference to the air vents used by the most luxurious vehicles to lessen turbulence in the wheel wells. They have no use other than aesthetic appeal and serve as a distant relative of the Sienna’s Y-shaped taillight treatment on the Lexus LC500.
Not only are SUVs and pickup trucks well-suited for tailgating, but other cars as well. The hatch serves as the rearmost speaker for the JBL stereo of the Sienna.

Taking Technology To New Levels
The all-new 2021 Toyota Sienna redefines the minivan segment with an emphasis on space and design to support a wider range of life phases and activities.
The fourth-generation Sienna is equipped with a variety of new technologies that increase the bar for style, safety, comfort, versatility, and fuel efficiency in its segment. It was designed and engineered in the United States. There are five different Sienna trim levels for 2021, with content varying significantly between LE, XLE, XSE, Limited, and Platinum. The first thing you should do when one enters your facility is to confirm the trim level, but there are also some other crucial elements you should be aware of.
BUILT ON A PROVEN PLATFORM
The Camry, Avalon, Venza, and RAV4 all share Toyota’s Global Platform K (TNGA-K), which is the foundation for the 2021 Sienna. The significant use of hot-stamped sheet steel, ultra-high tensile strength steel, as well as aluminum components to minimize weight and provide a rigid body structure, is what gives the TNGA-K platform its inherent strength.
As an illustration, the sliding doors are made of lightweight metal. You are aware that repairing an aluminum door panel differs from fixing a steel door. Before moving forward, you must take into account the extent, location, and accessibility of the harm.
The plant that makes the Sienna binds the first and second steel sheets from the outside by using Laser Pinning Welding (LPW) on various portions of the chassis (the outer panel and reinforcement). Always use LPW close to spot welding. The outside of LPW resembles that of laser screw welding. LPW can be recognized from Laser Screw Welding because the weld has a smaller diameter.
Use small diameter plug welding and adhere to the guidelines in the body repair handbook when doing LPW repairs. For more information, see “Precautions for Welding Document ID: RM100000001TW4D.”
HYBRID PLATFORM
The sealed Nickel-Metal Hydride (Ni-MH) hybrid battery for the Toyota Sienna’s SULEV status in 2021 is housed beneath the seats.
Both front-wheel drive and optional Electronic On-Demand All-Wheel Drive are offered for the Toyota Sienna. The Sienna uses a separate, rear-mounted electric motor that powers the back wheels as needed rather than the conventional transfer case and driveshaft. It functions perfectly, sending up to 80% of the driving force to the back wheels, reducing front wheel slide during off-the-line starts. Due to the lack of a transfer case or rear driveshaft, this arrangement also facilitates repairs.
AVAILABLE NEW FEATURES
Technology innovations abound in the 2018 Toyota Sienna to make driving safer and more convenient. The difficulty you face is that you must guarantee that those features are operational “as new” when you deliver the repaired car when one is brought in for collision repairs. We advise verifying any systems that might be impacted by an accident before you begin working and logging any difficulties you discover. Once the repairs are finished, verify the systems once more. new characteristics include:
- Heated steering wheel and power tilt and telescoping steering column (Platinum)
- Digital rear-view mirror
- When rear-seat occupants or cargo block the vision, it works like a regular mirror until the obstructions vanish at the touch of a switch, revealing the camera’s image from behind the car (optional on Limited and Platinum)
- Dual power sliding side doors with hands-free kick-open and close1 (standard on XLE, XSE, Limited and Platinum)
- Rear liftgate with hands-free operation (standard on XLE, XSE, Limited and Platinum)
- installation of a trailer hitch receiver or other accessories placed near the rear bumper may require deactivating or removing the kick sensor

What is the range of the Sienna battery?
Exclusively available in the 7-seat layout with Super-Long-Slide second-row captain’s chairs is the 2022 Sienna Woodland Edition. It is simple to load and carry outdoor equipment thanks to the Split & Stow 3rd Row Seat and the kick-activated power sliding rear doors. All three rows have seven USB ports, seven sunshades, and heated front seats to assure everyone’s comfort and convenience. (These items are optional or standard in other Sienna grades.)
The National Environmental Education Foundation (NEEF) will receive a $250 payment from Toyota for each 2022 Sienna Woodland Edition vehicle sold, with a minimum donation of $250,000 promised. The money will help NEEF accomplish its goal of improving people’s access to, understanding of, and connection to the environment.
The 2022 Sienna is available in LE, XLE, sporty XSE, opulent Limited, and ultra-plush Platinum trims in addition to the Woodland Edition. The 2022 Sienna follows Toyota history by coming well-equipped in the LE grade and adding more features and technology in the higher versions. The LE Plus, XLE Plus, and XSE Plus packages neatly bundle options.
The fourth-generation model elevates the third-generation Sienna’s “swagger wagon” moniker to a whole new level. With dark 20-inch split-5-spoke alloys, bolder appearing front and rear bumpers, and a sport-tuned suspension that is exclusive to the XSE, the ultra-athletic XSE variant amplifies the sporty aspect.
Depending on the model grade, the 2022 Sienna offers a variety of high-end features across its model line, including kick-open and closed sliding side doors and the rear gate, a four-zone climate control system, heated second-row Super-Long Slide captain’s chairs with ottomans, a power tilt and telescoping steering column with heated steering wheel, a digital rear-view mirror, a 10-inch color head-up display, and a 12-speaker JBL Premium Audio
The Limited and Platinum classes don’t come with any packages, but they do come with two factory options: a 1080p HD Entertainment Center with an 11.6-inch monitor, an HDMI connector, a remote control, and two wireless headphones; and a digital rearview mirror (also optional on XLE and XSE). For the XLE grade and higher, a 1,500-watt inverter with a 120V AC outlet is also available and might be used to power appliances during a power outage.
All 2022 Sienna models incorporate standard second-generation Toyota Safety Sense (TSS 2.0), a sophisticated active safety system that includes the following in addition to collision protection offered by the TNGA-K Platform:
- Pedestrian Detection Pre-Collision System
- With Lane Trace Assist, Lane Departure Alert
- Adaptive Cruise Control at Full Speed
- Auxiliary High Beams
- detection of cyclists
- Recognizing road signs
In certain emergency situations, the Pre-Collision System (PCS) with Pedestrian Detection is intended to offer automated braking capacity should the driver not respond in time. The PCS system is not only meant to detect a car ahead, but it can also recognize a bicyclist and even a pedestrian in low light scenarios. All Sienna vehicles come equipped with Blind Spot Monitor (BSM) and Rear Cross Traffic Alert (RCTA).
The 2022 Sienna has ten airbags, including curtain side airbags for all three rows in addition to the driver and front passenger airbags, driver’s knee airbag, passenger seat cushion airbag, front seat side airbags, and rear outboard seat side airbags. The Toyota Star Safety System incorporates Electronic Brake-force Distribution (EBD), Electronic Stability Control (VSC) with Traction Control (TRAC), Brake Assist (BA), Anti-lock Braking System (ABS), and Smart Stop Technology (SST).
Toyota goes above and above when it comes to safety with features like Rear Seat Reminder, Electric Parking Brake (EPB), and Rear Passenger Seatbelt Reminder. Rear occupant identification, which was created with family safety in mind, is based on door sequencing logic, and the Multi-Information Display issues a warning “Keep an eye out for passengers and cargo in the back seat.
Toyota has led the hybrid industry for more than 20 years, and the Sienna benefits from their well-known commitment to quality, dependability, and durability. The Toyota Hybrid System II in the Sienna generates a total system output of 245 horsepower and achieves an EPA-estimated 36 combined MPG fuel economy (front-wheel drive), the latter setting a standard for the segment. It also performs flawlessly and transparently.
The driver of the Sienna will experience incredibly smooth acceleration and barely detect any noise. Two electric motors operating in tandem with the high-efficiency 2.5-liter DOHC four-cylinder engine produce a notable boost in low-speed torque.
There is never a need to recharge the hybrid battery pack thanks to the Toyota Hybrid System. As the car is being driven, the Toyota Hybrid System II automatically charges the hybrid battery. The Sienna’s 18-gallon gasoline tank provides more than 600 miles of driving range, reducing the number of fuel stops required by drivers.
Additionally, the Sienna has a few performance-control surprises. The driver can customize the van’s driving style by choosing between EV, NORMAL, ECO, and SPORT driving modes. The NORMAL mode is best for regular driving, SPORT improves acceleration response, ECO maximizes fuel and battery efficiency, and EV mode enables electric-only travel over short distances at moderate speeds.
A sequential shifting option can be utilized by the driver to “downshift, which gradually amplifies the regenerative braking. It serves as a lower gear and increases the recovered energy transferred to the HV battery, making it perfect for driving in steep terrain, for instance. As a plus, Sienna’s hybrid technology boosts ride smoothness by accurately adjusting the drive torque to reduce pitch and dive under acceleration and deceleration.
With a staggering 14:1 compression ratio and Toyota D4-S fuel injection that provides 41% thermal efficiency, the Sienna’s gas engine is already a miracle in and of itself. Variable Valve Timing-Intelligent System by Electric Motor (VVT-iE) is used on the gas engine’s intake camshaft, while VVT-i is used on the engine’s exhaust camshaft. The efficiency of the engine is further increased by a fully variable oil pump and a variable cooling system (electric water pump and electric thermostat).
The Sienna’s instrument panel has a 7-inch color Multi-information Display with a Hybrid System Indicator that displays system output and regeneration status while promoting eco-friendly driving practices. The display offers the driver a game-like score feature and indicates the ideal acceleration rate for eco driving, just like on other Toyota hybrid cars.
Predictive Efficient Drive (PED) analyzes driving patterns and previously remembered road and traffic conditions to maximize hybrid battery charging while using navigation system operation (where enabled). The technology can become familiar with repetitive routes and forecast when and where the car would probably slow down or halt. Then, with proper accelerator pedal release timing guidance, PED can reduce energy consumption, especially while driving through hilly areas or in traffic congestion.
Why is there just a 1-MPG difference in EPA estimates between front-wheel drive and all-wheel drive Sienna models? Toyota’s ground-breaking Electronic On-Demand All Wheel Drive technology provides the solution. This AWD system uses a separate independent electric motor to power the rear wheels the moment additional traction is needed and at all vehicle speeds in place of a bulky AWD transfer case and space-robbing driveshaft to the wheels.
The Electronic On-Demand AWD system operates smoothly and transparently, just like the hybrid system. Hybrid AWD preemptively distributes up to 80% of torque to the rear wheels during off-the-line starts to help reduce front-wheel slip.
The Sienna’s handling is more assured thanks to the Hybrid AWD system’s contribution to the reduction of understeer, which also improves cornering agility. The distribution of torque then fluctuates depending on the situation, going from 100:0 for constant-speed driving to 20:80 for slick roads. The Multi-information Display shows the distribution of torque.
The new-generation Sienna, whether it is in front-wheel drive or all-wheel drive, provides a secure, responsive driving experience with exceptional ride comfort, in large part because of the TNGA-K Platform coupled with a trailing-arm multi-link rear suspension. The standard 20-inch aluminum-clad wheels with P235/50R20 tires for FWD are installed in the wheel wells of the sporty XSE and opulent Platinum grades. 18-inch wheels are standard on the Limited FWD grade. (Versions with all-wheel drive had 18-inch wheels.)
The design team carefully considered how to integrate the functional aspects of a minivan with the emotional need for a more individualized driving experience, taking into account the feedback from today’s minivan consumers who claim they do not want to feel like they are driving a bus. The upshot is that the fourth-generation Sienna is the most sophisticated, adaptable, and pleasurable vehicle ever thanks to clever solutions and first-rate comfort throughout the interior.
A super-modern instrument panel with a huge central touch display and useful storage capacity has bold, horizontal layers to depict a wide and expansive interior. The Bridge Console, a creative departure from typical minivan interior designs, gracefully joins the instrument panel to the center armrest while being ergonomically positioned high between the driver and passenger. The comfort of driving is improved by this distinctive feature. Along with cup holders, a wireless charger, and plenty of storage boxes for smaller items, the shifter and other important controls are all conveniently located. A sizable open space is provided underneath the bridge for the practical storing of larger bags or purses.
All passengers on board the Sienna have plenty of legroom, with the second row having 39.9 inches and the third having 38.7 inches. With all seats in place, there is ample cargo space, including 101.0 cubic feet behind the front seats, 75.2 cubic feet behind the second row with the third row folded, and 33.5 cubic feet.
The Sienna LE and some XLE models are available with 8-seat arrangements that include a middle seat that can be stored. When combined with the available ottoman function, the Super Long Slide second-row captain’s seats in some 7-seat models slide 25 inches, offering exceptional legroom and flexibility to optimize comfort. (Standard is offered for some other people in Limited and Platinum.)
The 2022 Sienna incorporates a number of features that make the cabin quieter than a library, just like all Toyota cars produced on the TNGA-K Platform. Toyota engineers worked to minimize sounds at the frequencies used for speech. The TNGA-K Platform’s strong strength prevents noise intrusion and minimizes vibration in the steering, floor, and vehicle structure. Outside noises are further kept outside thanks to body sealant and extensive, well-placed noise insulation.
Conversation is only one of the things that is made better by the quieter inside thanks to all the onboard connectivity Sienna offers (seven USB ports, accessible WiFi, optional JBL 1,200-watt amp/12-speaker Premium Audio, and 1080p HD back entertainment system).
The Sienna’s unique optional Driver Easy Speak is the driver’s best friend if interior noise level should escalate, for example owing to a little argument between a few teenage passengers. This useful feature, which debuted on the third-generation Sienna, is effectively a built-in PA system that sends the driver’s voice directly to the source of the commotion through the audio system’s rear speakers.
The Sienna has consistently provided a high, expansive view of the road that gives the driver a sense of security. The Sienna is a great vehicle for sightseeing because of its high sitting position and large windows, and the privacy glass behind the front row prevents passengers from feeling cramped.
The Sienna has improved its great outward visibility and sightlines over the years with technology to help drivers see more of the area behind and surrounding the car. The newest version of that technology is delivered by the fourth-generation model.
- While higher end models have a wide-angle monitor to show even more of what is behind the car, the typical backup camera shows a projected route. Most of the time, a digital rear-view mirror that is available performs as a regular mirror. A switch that transforms the rearview mirror into the image of the camera from behind the vehicle can be used to clear obstructions caused by people or cargo in the backseat. The digital mirror incorporates a HomeLink transceiver as well for easy control of connected devices like garage doors.
- A live, 360-degree view is provided by the optional Bird’s Eye View Camera with Perimeter Scan to aid the driver in spotting potential obstructions. This is crucial for spotting toddlers or small animals that may be around the car. When parking, Curb View can prevent scratches on the alloy wheels.
- A 10-inch color head-up display with steering wheel controls is standard on the Sienna Platinum. At eye level, the display presents crucial data such as speed, navigational instructions, and TSS 2.0 features.
With adaptable Toyota Audio systems offering something for everyone, the 2022 Sienna delivers a feast of connectivity and entertainment.
- Toyota Audio (standard on LE grade): features a 9-inch touchscreen, six speakers, Android AutoTM, Apple CarPlay and Amazon Alexa compatibility, seven USB media ports, hands-free phone capability and music streaming via Bluetooth wireless technology, Safety Connect with a 1-year trial, and Wi-Fi Connect with up to 3 GB during a 30-day trial.
- AM/FM/HD radio, eight speakers, Siri Eyes Free, Safety Connect with a 3-year trial, and Wi-Fi Connect powered by AT&T are all included with Toyota Audio Plus (standard for XLE, optional for LE) (up to 3GB within a one-month trial).
- The Toyota Audio Plus system now includes navigation thanks to the Toyota Premium Audio with Dynamic Navigation (standard on XSE).
- Toyota Premium Audio with Dynamic Navigation and JBL Premium Audio (standard for Limited and Platinum, optional for XLE and XSE): 12 speakers, including a subwoofer, 1,200 watts of amplifier power, as well as Clari-Fi digital restoration are included.
All parts, excluding those that would typically require wear and maintenance, are covered by Toyota’s standard 36-month/36,000-mile new-vehicle guarantee. The powertrain is covered by additional 60-month warranties for 60,000 miles and corrosion without a mileage cap. The Hybrid System Warranty covers all HV parts for 8 years or 100,000 miles. The hybrid battery guarantee has also been extended to 10 years or 150,000 miles, whichever comes first. The Sienna also has ToyotaCare as standard equipment, which provides 24-hour roadside assistance and routine factory-scheduled maintenance for two years or 25,000 miles, whichever comes first.
