By setting the transmission to D3, you are instructing it to stay in third gear. If you put it in D, you’ll let it shift into the fourth and fifth gears as needed. If you leave it in D3 when driving normally and without towing anything, it won’t use the higher gears, resulting in greater engine RPMs and worse fuel economy.
I’m unsure of the gear ratios in the Pilot’s gearbox, but typically, fourth gear has a ratio of one to one and fifth gear has a ratio of about eight to one. In order to travel the same distance in typical driving, you would at the very least be wearing out the engine much more quickly and burning up much more fuel. In everyday driving, using D instead of D3 would result in significantly higher fuel efficiency and reduced engine wear.
When using D3 while traveling downhill, you partially replace the conventional brakes with the engine and transmission. When that happens, I briefly utilize D3 and try to slow the car down to make up for it.
There are no photographs of the convex mirrors, which I have in the lower inner corner of each mirror. Keep the spherical part on the glass, but be sure to leave enough space for the electric mirror to move through its complete range of motion.

Why is D3 on my Honda Pilot?
You’re in error.
When pressed, the “D3” button at the end of the gear selector lever will put the transmission into “D3.” This is intended to aid the brakes in slowing the vehicle down when it is towing or pulling a big load and traveling down a steep incline.
What does the D3 warning light signify?
The service code D3 is not one. When you press the button on the end of the shift level, an indication to the right of the “D” (Drive) indicator on the dashboard illuminates. Only the bottom three gears will be selected when the transmission is lighted. When towing heavily laden trailers or up or over big hills or mountains.
Can I always operate a vehicle in D3?
No. Because D3 is typically used to enable braking when traveling down a steep hill, it is not recommended for highway driving. Additionally, D3 offers the fastest speed possible in stop-and-go traffic, particularly in crowded cities. It is most effective when traveling at speeds of 30 mph or less.
#1: Saves maintenance cost
You won’t need to apply the brakes to slow down on downhill routes since D3 will cause your car to engine brake. You will save money by occasionally replacing your brake pads, especially if the route is extremely steep and forceful braking is necessary.
Even if new brake pads are not particularly expensive, you still need to take them to your neighborhood auto shop, which could take some time. You can save some money on maintenance, some time, and you’ll be safer when you’re driving downhill if you just switch to the D3 mode.
#2: Better throttle response
As previously stated, the D3 setting is best for city driving. This is due to the fact that when you step on the gas in third gear, your RPMs increase at lower speeds. Additionally, you can use the D3 if you intend to accelerate quickly because third gear allows for high RPMs before changing to the next.
Return to D mode if you are about to slow down so that it can choose the appropriate gear based on your speed and RPM.
#3: Safer drive
Your automatic transmission’s D3 setting tends to give you better control of your vehicle. As a result, when your vehicle is in D3, you can prevent slipping to other lanes, especially in rainy weather. When your car is moving at a high speed in a high gear, the wheel will spin too quickly and you could lose traction.
If you suddenly step on the accelerator, the engine braking system will also assist you in maintaining a specific speed.
What uses does D3 have?
A fat-soluble vitamin called vitamin D (also known as ergocalciferol-D2, cholecalciferol-D3, and alfacalcidol) aids in the body’s absorption of calcium and phosphorus. For the purpose of creating and maintaining strong bones, the proper amounts of calcium, phosphorus, and vitamin D must be consumed. Bone problems can be treated and prevented using vitamin D. (such as rickets, osteomalacia). The body produces vitamin D when skin is exposed to sunshine. You might not get enough vitamin D from the sun if you use sunscreen, wear protective gear, spend little time in the sun, have dark skin, or are older. Calcium and vitamin D are combined to treat or prevent bone loss (osteoporosis). Additionally, vitamin D is used with other drugs to treat low calcium or phosphate levels brought on by specific illnesses (such as hypoparathyroidism, pseudohypoparathyroidism, familial hypophosphatemia). It can be used to maintain normal calcium levels and support healthy bone formation in patients with renal disease. Infants who are breastfed typically receive vitamin D drops or other supplements since vitamin D levels in breast milk are typically low.
What does the automatic transmission symbol D3 mean?
D3 (or 3) As suggested by the name, the D3 (or occasionally just 3) mode restricts your car to its first three gear ratios, or in some cases locks it in third gear only. If the maximum RPM is reached, it will change into a higher gear, just as the 2 and L.
Traveling Downhill
Truck drivers are skilled at navigating high hills. They frequently use engine braking to reduce speed, and you can use the D3 gear to do the same.
D3 lessens the load on the braking system, preventing the brake pads from overheating. The engine will control the speed by using this lower gear. Long-term use of high RPMs, however, can potentially wear down the engine.
Driving Uphill
D3 could be helpful if you need to pick up speed when going uphill. You see greater RPMs that transfer into speed because D3 prevents the transmission from moving into overdrive.
You don’t want to put too much strain on the transmission, as with all other driving circumstances. It will be better to shift back into overdrive if you reach a reasonable speed but the RPMs continue to be excessive.
Navigating Slippery Surfaces
Getting stuck is simple when driving on slick surfaces. However, D3 prevents gear slippage, which helps your car maintain control.
You have less of a risk of becoming stuck in inclement weather if the transmission can only shift into third gear. The wheels continue to gain the traction necessary to escape challenging circumstances by locking it in place.
Accelerating Quickly
It is challenging to get the acceleration required to move out into congested traffic if the transmission shifts too soon. Even if you depress the throttle pedal, the automobile hardly seems to be moving forward.
The car cannot shift into higher gears when it is in D3. As a result, the RPMs increase more quickly, enabling greater acceleration.
Carrying Heavy Loads
When towing a trailer or hauling freight, it’s crucial to keep an eye on the speed of the vehicle. Nevertheless, you shouldn’t ride the brakes because doing so makes them overheat and fade.
Speed is restricted to that which is possible in the third range while using D3 gear. Usually, this is sufficient speed for daily driving and gives you greater control when you are carrying a lot of weight.
D3 on my dashboard—what is it?
You can push the button to rapidly gain greater strength when you need it to climb a hill. Simply press the little button once more to disengage. When this D3 button is depressed, your car can be held back when descending a hill without using the brakes.
Why is my Honda Pilot drive light blinking?
A transmission problem is indicated by a flashing D light. This could be electrical, like your transmission speed sensor, or mechanical, like your shift solenoid. This may also indicate that there is not enough transmission fluid in your vehicle.
How to inspect the transmission fluid in Honda Pilot?
Pull the dipstick on the transmission body’s right side to check the automatic transmission fluid (ATF) level (car on level ground while the engine is off). Clean your dipstick by removing it. Re-insert your dipstick, then take it out to check the level of your fluid. Your fluid level needs to fall between the marks.
The D light is blinking, but can I still drive?
You have a bad transmission if your Honda’s dashboard’s D light is blinking or flashing. A qualified mechanic should evaluate the vehicle right away and conduct a thorough diagnosis to rule out any potential causes of the issue.
The following are some typical causes of the Honda D light blinking:
- faulty or unsuccessful shift solenoid
- low level of transmission fluid
- incorrect pressure switch
- Your transmission has a mechanical problem.
Driving on while your D light is flashing can seriously harm your transmission. As soon as the light turns on, you should get the problem investigated.

What does the Honda Pilot’s D4 stand for?
Drive (D4)
Put yourself in this position and drive as usual. The transmission automatically chooses the best gear based on your acceleration and speed. When the engine is cold, you could find that the transmission shifts up at greater speeds. The engine warms up more quickly as a result. Driving.
Can you shift gears in an automatic vehicle?
A spinning coupling mechanism in the transmission that can prematurely fail if it becomes worn from a quick gear change can be severely damaged by shifting too quickly while your automobile is still moving. Before changing into a different gear, always come to a complete stop.
