When the Audi A4 is stopped, depress the brake pedal (for instance at traffic lights).
Before starting off on steep inclines, apply the parking brake to stop the Audi A4 from rolling. WARNING!.
The parking brake will be automatically disengaged as soon as you begin to accelerate normally while wearing your seatbelt, and the Audi A4 will then begin to move.
The Audi A4 may roll away if the driver’s door is opened with the selection lever not in the P position. Gearbox: selection lever in gear! will be displayed. There will also be a buzzer.

Why does the Audi d/s stand for?
Seven gears that change quickly without sacrificing traction
A new stage in the development of transmission systems is introduced by Audi. The seven-speed S tronic moves very quickly and with great efficiency. The new dual-clutch transmission is made to work with quattro all-wheel drive and an engine that is placed longitudinally. In the second part of 2008, it will go into production and is appropriate for a variety of sporty vehicles. Audi offers a wide variety of various transmission innovations, with the perfect option for every purpose, in addition to the new seven-speed S tronic.
Audi is starting a new chapter in its driveline strategy with the seven-speed S tronic. The brand-new transmission, which Audi exclusively developed, is designed for sporty mid-range cars. It is a high-tech part that Audi has created to be responsive and extremely effective.
The new seven-speed S tronic from Audi has several modes of operation. The completely automatic mode offers the D (Drive) and S (Sport) programs, in which the computer chooses the gears.
The selection lever or the optional rocker switches on the steering wheel can be used to manually swap the gears, which is an extremely quick process. The change response is incredibly accurate, fluid, and dynamicall hallmarks of an Audi transmission.
There are two part-transmissions in the seven-speed S tronic. It has two integrated multidisk clutches that can engage and disengage various gears. The 1, 3, 5, and 7 odd-numbered gearwheels receive engine torque through a solid shaft via the huge outer clutch K1. These are situated toward the middle of the vehicle, in the rear section of the aluminum enclosure.
Around the solid shaft rotates a hollow shaft. It is attached to the smaller K2 clutch, which engages and disengages the even-numbered gears 2, 4, and 6 as well as reverse, and is housed inside the bigger clutch. On the two output shafts, all the gearwheels are positioned one behind the other in the following order: 4, 6, 2, R, 1, 3, 7, 5.
Although both part-transmissions are always in use, only one is ever physically connected to the engine. For instance, if the car is accelerating in third gear, the second section of the transmission will already be in fourth gear. The clutches are engaged during the shifting operation, and as K1 opens, K2 shuts incredibly quickly. This procedure is finished without affecting traction in just a few hundredths of a second. The driver scarcely notices it because it is so smooth and comfy.
The self-locking center differential of the quattro drivetrain receives power from the drive shaft and divides it into two directions. In the typical torque distribution pattern, 40% of the torque travels via a side shaft to the front-axle differential’s bevel pinion and 60% of the torque travels by the propeller shaft to the rear-axle differential. This shaft is hollow as well, reducing weight. The center differential has the ability to send up to 85% of the power to the rear axle or up to 65% to the front axle as needed.
How do D and S work in an automatic car?
D denotes the default Drive mode. Drive mode in other automobiles is comparable to this. When driving in the S mode, which stands for Sports mode, a few extra functions will be activated. In order to drive your car in either the D or the S mode, simply shift the gearbox to the appropriate position.
What is forbidden in an automatic vehicle?
Driving a manual car is less direct and more complex than driving an automatic or a car with a CVT gearbox. However, if done incorrectly, you risk damaging your vehicle, and at that point, even mechanics won’t be able to assist you.
Here are the top 4 things to be on the lookout for when operating an automatic vehicle.
1. Never use neutral to coast down a slope
Although you do save a tiny amount of fuel when coasting down a slope in neutral, Modern automatic gearboxes cut off the gasoline flow to the engine when you are in gear, traveling up and down hills, then climbing another hill. You will therefore only use the engine and wheels, which are linked to the transmission. By using an automatic vehicle, you can save fuel in this way.
As the car can no longer accelerate to complete the length while coasting down a slope in neutral, you take control of it.
Another reason is that when you coast down a hill in neutral, you deprive the car of control because it can no longer accelerate to finish the stretch.
2. Completely stop the vehicle before shifting into reverse.
When moving from drive to reverse or from reverse to drive in an automatic transmission car, you always want to be sure that you come to a complete stop first. This is necessary since you are stopping the car using your brakes, not your transmission. While your brakes are made to stop the car, the gearbox in an automatic vehicle is made to change gears.
3. Do not accelerate your car.
Never launch your vehicle if you want it to last as long as possible. It will just subject the car to great pressure and stress.
One habit that many people who drive automatic cars have is revving the engine in neutral before putting the car in drive to move forward. This must be avoided. It won’t do anything but harm the automatic gearbox, and replacing one is pricey. The proper procedure is to engage drive mode on the gearbox and begin driving. It’s that easy.
The engine continues to operate while being idle by maintaining the gearbox in drive mode.
4. Never put the car in neutral while waiting for a signal.
There is no justification for shifting into neutral while waiting for a signal. It’s okay to leave it in drive, and against popular belief, shifting back to neutral won’t actually save fuel. It will just increase the gearbox’s stress.
The engine continues to operate while being idle by maintaining the gearbox in drive mode. While placing the car in neutral and switching to drive mode as soon as you start moving merely results in that additional fuel usage.
While most of these ideas are common knowledge, we thought it would be worthwhile to highlight them for individuals who may have been doing things incorrectly up to this point. The aforementioned pointers are some of the fundamental guidelines for operating an automatic transmission car to ensure a comfortable and hassle-free journey.
Can you drive while changing from D to M?
A query regarding using a modern automatic transmission with the manual option came from a reader. His query is as follows:
“Top Gear PH, hello! In an automatic vehicle, is it acceptable to switch from drive to manual (+/-) while I’m cruising? I’m hoping you can respond to my query. So excited! I’m grateful.”
There is nothing to worry about and you can. This is what these contemporary automatic transmissions with a manual mode are designed to do. It was designed to go from automated to manual mode, even while traveling at a high speed.
A few improvements to the automatic transmission have been made in the last ten years or so. Modern automatic transmissions now have a manual mode that allows the driver to manually shift gears, a feature that was first offered in exotic automobiles. However, unlike a true manual transmission, which uses a pedal to drive a hydraulic or cable-controlled clutch, modern manual transmissions just have switches or a shifter that needs to be tugged or pushed to change speeds.
With these gearboxes, the driver is free to choose a certain gear whenever they want. The ability to select one gear and maintain it gives the driver additional control in manual mode. The more control you have as a driver, the better.
Here are a few situations where using manual mode is beneficial:
The S on the Audi gear shifter stands for what?
S mode modifies the transmission’s shift points. It responds more sportily since it holds each gear for longer while accelerating and downshifts earlier when slowing down.
Is driving in sport mode better?
Sport mode usage isn’t always detrimental to your car, especially for brief periods of time. However, it takes more gas and will quickly wear down your engine compared to conventional driving.
Your engine will work harder in sport mode. But it shouldn’t have a significant impact on your automobile as long as you don’t use sport mode frequently for extended periods of time.
Sport mode’s primary drawback is that it reduces gas mileage. Sport mode consumes more fuel than normal driving, resulting in higher gas costs and faster gas consumption. Even though, as I said, this effect won’t necessarily harm your car, it might hurt your wallet.

When should an automatic transmission be changed?
Because changing gears involves being in the proper gear for the driver’s needs, advanced drivers will opt to change gears more frequently than rookie drivers.
Drivers of automated cars can opt to change gear only when necessary, as contrast to manual car drivers who must constantly shift gears. For regular driving, the procedure is very simple: move up a gear when the revs reach 2500-3000 rpm, and switch down a gear if they fall below 1000-1500 rpm. When changing gears, wait if you need additional acceleration, but don’t let the automobile cross the red line. People who advise changing from first to second gear when traveling at 10 km/h should not be believed because it depends entirely on the vehicle and the circumstances.
The only thing that separates a manual gearbox from an automated transmission is that with a manual gearbox, you must manually change gears in order to avoid going over the vehicle’s rev limiter. This is done automatically via automatic gearboxes. It is advantageous to be able to shift gears in an automated car since automatic gearboxes cannot predict changes in the road ahead.
When should a gear change be made?
Stick shift driving requires a lot of work and perseverance to master. Practice in an empty parking lot after becoming familiar with the various manual moves until you feel entirely comfortable using it on the road.
First, let’s get familiar with some of the parts
Clutch PedalUnlike automatics, which only have two pedals, manuals have three. The pedal that is farthest to the left is the clutch pedal. It is used when changing up or down, including into neutral, from one gear to the next. The clutch disengages when it is fully depressed. Clutch engagement and power transmission are ready to continue when the clutch pedal is removed.
Similar to an automatic, use your right foot for the gas and brake and your left foot for the clutch.
Stick, “Gear Shifter,” etc.
The shift lever is positioned in the center console of contemporary manual automobiles. Older vehicles could have a shifter positioned on the dash or the steering column. Find your stick shift and look it over.
There are up to 6 gears in manual automobiles. The head of the stick shift is often where the gear guide is positioned. The middle of the “H pattern is typically designated as neutral, which is not a gear and does not move you forward. The letter “R” stands for “reverse.”
Emergency BrakeSince stick shift vehicles lack a “park gear, the emergency brake is very crucial. When parking and stopping on hills, use the emergency brake to stop the car from rolling.
Next, practice with the engine off and emergency brake engaged
Find the clutch before starting the car. When changing gears, the clutch must be depressed! Practice putting your left foot on the clutch pedal and releasing it. You’ll start to notice when the clutch is engaged or disengaged (in your foot).
Depress the clutch all the way once you’ve gotten a feel for it, then shift into first gear. Then, while depressing the gas pedal, start releasing the clutch with your left foot (this is often referred to as “feathering”). If the car were running, you would start to move.
Release your foot from the gas and continue in the same manner to shift into higher gears:
- Activate the clutch
- Change to the next highest gear with the shifter.
- Release the clutch while applying pressure to the gas pedal.
You essentially do the same thing when you downshift. While shifting, take your foot off the gas pedal.
- Put the gearshift in the next lower position.
- Release the clutch while gradually depressing the gas pedal.
Practice in an empty lot
When the automobile is not moving, using the clutch and shifter is one thing; when the car is moving, it is quite another. Find a vacant parking lot and practice shifting while driving after you have practiced shifting with the car off.
The clutch and brake pedals should be depressed simultaneously while the automobile is in neutral and the ignition is turned on.
- Put the automobile in first gear with the clutch and brake pedals pushed.
- Put the parking brake on.
- Release your foot from the brake pedal, then gradually depress the gas pedal while releasing pressure from the clutch pedal. While the left foot releases the clutch, the right foot will be pressing down on the gas pedal. This requires practice. If you don’t do this correctly, the clutch may “pop,” sending the car lurching forward and stalling.
- Simply engage the emergency brake, depress the clutch pedal, and shift into neutral to restart the vehicle if it stalls.
- Keep your foot on the gas pedal until the tachometer reads somewhere between 250 and 3,000 RPM. Remove your foot from the gas pedal, depress the clutch pedal, and select the second gear. Before shifting, make sure the clutch is fully depressed. If not, you could “grind the gears. Next, begin releasing the clutch while giving the vehicle gas. Avoid “riding the clutch,” which is when you continue to accelerate while keeping your foot on the clutch.
- The process for changing into higher gears remains the same as your speed increases. Generally speaking, the mph ranges for the various gears are as follows:
