150Driving
Basic requirements for the Start-Stop mode
● The driver door must be closed.
● The driver must have their seat belt fastened.
● The bonnet must be closed.
● The vehicle must have travelled at more than 4 km/h (2 mph) since the
last stop.
● The vehicle cannot be towing a trailer.
WARNING
● Never switch the engine off until the vehicle is stationary. The brake
servo and power steering functions will not be completely covered under
warranty. More force may also be needed to turn the steering wheel or to
brake. As you cannot steer and brake in the normal manner, there is a
greater risk of accidents and serious injury.
● Never remove the key from the ignition if the vehicle is in motion.
Otherwise, the steering could lock making it impossible to steer the vehi-
cle.
● Always take the ignition key with you whenever you leave the vehicle,
even temporarily. This is particularly important if there are children in
the vehicle, as they might otherwise be able to start the engine or use
power-operated equipment (e.g. the electric windows), which could
cause injuries.
● To avoid injury, make sure that the Start-Stop system is switched off
when working in the engine compartment ⇒ page 152.
CAUTION
The Start-Stop system must always be switched off when driving through
flooded areas ⇒ page 152. Stop/Start the engine
Vehicles with a manual gearbox
–
When the vehicle is stopped, put it into neutral and release the
clutch pedal. The engine will switch off. The warning lamp 
will appear on the instrument panel display.
– When the clutch pedal is pressed the engine will start up again.
The warning lamp will switch off.
Vehicles with an automatic gearbox
– Use the foot brake to bring the vehicle to a stop and keep the
brake pedal pressed down with your foot. The engine will switch
off. The warning lamp  will appear in the display.
– When you take your foot off the brake pedal the engine will start
up again. The warning lamp will switch off.
Additional information related to the automatic gearbox
The engine stops when the selector lever is in the positions P, D, N and S, in
addition to when in manual mode. With the selector lever in position P, the
engine will also remain switched off when you take your foot off the brake
pedal. In order to start the engine up again the accelerator must be press-
ed, or another gear engaged or the brake released.
If the selector lever is placed in position R during the stopping phase, the
engine will start up again.
Change from position D to P to prevent the engine from accidentally starting
when changing and passing by position R. 

Driving
Note
● You can control whether the engine should switch off or not by reducing
or increasing the brake force applied. While the vehicle remains stopped,
the engine will not stop if the brake pedal is slightly pressed, in traffic jams
with frequent stopping and starting for example. As soon as strong pressure
is applied to the brake pedal, the engine will stop.
● In vehicles with manual gearbox, during the stopping phases the brake
pedal must remain depressed to prevent the vehicle from moving.
● If the engine stalls in vehicles with manual gearbox, it can be directly
started up again by immediately pressing the clutch pedal. 
General notes
The system can interrupt the Start-Stop mode frequently for
different reasons.
The engine does not switch off
Before the stopping phase, the system verifies whether certain conditions
are met. The engine does not switch off, in the following situations for ex-
ample:
● The engine has not yet reached the minimum required temperature for
the Start-Stop mode.
● The interior temperature selected for the air conditioner has not yet
been reached.
● The interior temperature is very high/low.
● Defrost function button activated ⇒ page 135.
● The parking aid* is switched on.
● The battery is very low.
● The steering wheel is overly turned or is being turned.
● If there is a danger of misting. ●
After engaging reverse gear.
● In case of a very steep gradient.
The indication  is shown on the instrument panel display, and in addition,
the driver information system* shows, .
The engine starts by itself
During a stopping phase the normal Start-Stop mode can be interrupted in
the following situations: The engine restarts by itself without involvement
from the driver.
● The interior temperature differs from the value selected on the air condi-
tioner.
● Defrost function button activated ⇒ page 135.
● The brake has been pressed several times consecutively.
● The battery is too low.
● High power consumption.
Note
In vehicles with an automatic gearbox, if the selector lever is placed in posi-
tion D, N or S after engaging reverse gear, the vehicle must be driven at a
speed faster than 10 km/h (5 mph) for the system to return to conditions in
which the engine can be stopped. 

Driving
● Press and hold the clutch pedal to the floor.
● Place the gearbox lever in the required position ⇒ 
.
● Release the clutch pedal to engage clutch.
In some countries the clutch pedal must be fully pressed down for the en-
gine to start.
Selecting reverse gear
● Engage reverse gear only when the vehicle is stopped.
● Press and hold the clutch pedal to the floor ⇒ 
.
● Move the gearbox lever into the neutral position and press it down.
● Move the gearbox lever completely to the left and then forwards to posi-
tion it in reverse gear ⇒ Fig. 89 R
.
● Release the clutch pedal to engage clutch.
Changing down gears
While driving, changing down a gear must always be done gradually, i.e. to
the gear directly below and when the engine speed is not too high ⇒ 
.
Changing down while bypassing one or various gears at high speeds or at
high engine speeds can damage the clutch and the gearbox, even if the
clutch pedal remains depressed ⇒ 
.
Kick-down
In vehicles with a speed limiter, the kick-down function enables the pro-
grammed speed to be exceeded deliberately, i.e. when overtaking.
When the accelerator is pressed to the floor, the speed limiter is temporarily
deactivated as the programmed speed is exceeded.
When the speed of the vehicle falls below the programmed value again, and
when the accelerator is not pressed to the floor, the speed limiter is reacti-
vated.
WARNING
When the engine is running, the vehicle will start to move as soon as a
gear is engaged and the clutch released. This is also the case with the
electro-mechanical parking brake switched on.
● Never engage reverse gear when the vehicle is moving.
WARNING
If the gear is changed down inappropriately by selecting a gear that is
too low, you may lose control of the vehicle, causing an accident and se-
rious injuries.
CAUTION
When travelling at high speeds or at high engine speeds, selecting a gear
that is too low can cause considerable damage to the clutch and the gear-
box. This can also occur if the clutch pedal is pressed and held and it does
not engage.
CAUTION
To prevent damage and avoid premature wear, please observe the follow-
ing:
● Do not rest your hand on the gear lever while driving. The pressure ap-
plied by your hand is transmitted to the gearbox selector forks.
● Always ensure that the vehicle is completely stopped before engaging
the reverse gear.
● Always press the clutch to the floor when changing gears.
● Never hold the vehicle “on the clutch” on hills with the engine on. 

Automatic gearbox/DSG automatic gearbox*
Introduction
Your vehicle is equipped with an electronically controlled manual gearbox.
Torque between the engine and the gearbox is transmitted via two inde-
pendent clutches. They replace the torque converter found on conventional
automatic gearboxes and allow for smooth, uninterrupted acceleration of
the vehicle.
The tiptronic system allows the driver to change gears manually if desired
⇒ page 159, Changing gears in tiptronic mode*. 
Selector lever positions
The selector lever position engaged is highlighted on the display in the in-
strument cluster. With the selector lever in the manual gearbox positions G,
D, E and S, the engaged gear is also indicated on the display.
P – Parking lock
When the selector lever is in this position, the driven wheels are locked me-
chanically. The parking lock must be engaged only when the vehicle is sta-
tionary ⇒ 
.
The interlock button (the button on the selector lever handle) must be
pressed in and simultaneously the brake pedal must be depressed before
moving the selector lever either in or out of position P.
R – Reverse gear
Reverse gear must be engaged only when the vehicle is stationary and the
engine is idling ⇒ 
.
To move the selector lever to position R, the interlock button must be press-
ed in and at the same time the brake pedal must be depressed. The reverse lights come on when the selector lever is in the R position with the ignition
on.
N – Neutral (idling)
With the selector lever in this position, the gear is in neutral.
D/S – Permanent drive (forward) position
The selector lever in the D/S position enables the gears to be controlled in
normal mode (D) or Sport (S). To select Sport mode (S), move the selector
lever backwards. Moving the lever again will select normal mode (D). The
selected driving mode is shown on the instrument panel display.
In normal mode
(D), the gearbox automatically selects the best gear ratio.
This depends on the engine load, the road speed and the dynamic gear
control programme (DCP).
Sport mode (S) must be selected for a sporty driving style. This setting
makes use of the engine's maximum power output. When accelerating the
gear shifts will be noticeable.
The brake pedal must be pressed when moving the selector lever from D/S
to N if the vehicle is stationary or at speeds below 5 km/h (3 mph) ⇒ 
.
Under certain circumstances (e.g. when driving in mountains) it can be ad-
vantageous to switch temporarily to tiptronic mode ⇒ page 159, in order to
manually select gear ratios to suit the driving conditions.
WARNING
● Take care not to accidentally press the accelerator pedal when the ve-
hicle is stopped. The vehicle could otherwise start moving immediately
(in some cases even if the parking brake is engaged) resulting in the risk
of an accident.
● Never move the selector lever to R or P when driving. Failure to do so
could result in an accident. 

155
Driving
WARNING (Continued)
● With selector lever in any position (except P) the vehicle must always
be held with the foot brake when the engine is running. This is because
an automatic gearbox still transmits power even at idling speed, and the
vehicle tends to “creep”. The accelerator pedal must on no account be
pressed inadvertently when a gear is engaged with the vehicle station-
ary. The vehicle could otherwise start moving immediately (in some ca-
ses even if the parking brake is engaged) resulting in the risk of an acci-
dent.
● While you are selecting a gear and the vehicle is stopped with the en-
gine running, do not accelerate. Failure to do so could result in an acci-
dent.
● As a driver you should never leave your vehicle if the engine is run-
ning and a gear is engaged. If you have to leave your vehicle while the
engine is running, you must apply the handbrake and engage the parking
lock P.
● To avoid accidents, apply the handbrake and put the selector lever in
position P before opening the bonnet and working on the vehicle with
the engine running. Please always observe the important safety warn-
ings ⇒ page 209, Working on components in the engine compartment.
Note
● If the selector lever is moved accidentally to N when driving, release the
accelerator and let the engine speed drop to idling before selecting gear
range D or S again.
● Should the power supply to the selector lever be interrupted in posi-
tion P, the selector lever will be locked. If this should happen the manual
release can be used ⇒ page 163. Selector lever lock
The selector lever lock prevents gears from being engaged
inadvertently, so that the vehicle is not set in motion unin-
tentionally.
Fig. 90 Selector lever
lock
The selector lever lock is released as follows:
– Switch the ignition on.
– Press the brake pedal and at the same time press in the inter-
lock button.
Automatic selector lever lock
With the ignition switched on, the selector lever is locked in the positions P
and N. The brake pedal must be pressed to release the lever while pressing
the release button if the selector lever is in the position P. As a reminder for
the driver, with the lever in positions P or N the following message will be
shown on the display: When stationary, apply footbrake while selecting a gear. 
Safety FirstOperating instructionsPractical TipsTechnical specifications

156Driving
The selector lever lock only works if the vehicle is stationary or driving at
speeds up to 5 km/h (3 mph). At higher speeds the selector lever lock in
the N position is disengaged automatically.
The selector lever lock is not engaged if the selector lever is moved quickly
through position N (e.g. when shifting from R to D). This makes it possible,
for instance, to rock the vehicle backwards and forwards if it is stuck. The
selector lever lock engages automatically if the brake pedal is not de-
pressed and the lever is in position N for more than about two seconds.
Interlock button
The interlock button on the selector lever handle prevents the driver from
inadvertently engaging certain gears. Press the button in to disengage the
selector lever lock. The selector lever positions in which the interlock button
has to be pressed are shown in the illustration, highlighted in colour
⇒  Fig. 90.
Safety interlock for ignition key
Once the ignition has been turned off, the key may be removed only if the
gear selector is in position P. While the key is not in the ignition, the selec-
tor lever is locked in position P.
Note
● If the selector lever lock does not engage, there is a fault. The transmis-
sion is interrupted to prevent the vehicle from accidentally moving. Follow
the procedure below in order for the selector lever lock to engage again:
● >With a 6-speed gearbox: press the brake pedal and release it again.
● >With a 7-speed gearbox: press the brake pedal. Move the selector lever
to position P or N and subsequently engage a gear.
● Despite a gear being engaged, the vehicle does not move forwards or
back. Proceed to the next mode: ●
When the vehicle does not move in the required direction, the system
may not have the gear range correctly engaged. Press the brake pedal and
engage the gear range again.
● If the vehicle still does not move in the required direction, there is a sys-
tem malfunction. Seek specialist assistance and have the system checked. 
Driving tips
The gearbox changes gear ratios automatically as the vehi-
cle moves.
The engine can only start with the selector lever in the position P or
N. At low temperatures, below -10 °C (50 °F), the engine can only
start with the selector lever in the position P.
Starting the vehicle
– Press and hold the brake pedal.
– Press and hold the interlock button (the button in the selector
lever handle), move the selector lever to the desired position,
for instance D ⇒  page 154, and release the interlock button.
– Wait for the gearbox to engage the gear (a slight movement can
be felt).
– Release the brake and press the accelerator ⇒ 
.
Stopping briefly
– Apply the foot brake to hold the vehicle when stationary (for in-
stance at traffic lights). Do not press the accelerator. 

Driving
Stopping/Parking
If the driver door is opened and the selector lever is not in position
P, the vehicle could move. Driver message:  Gear change: selector
lever in drive position! will be displayed. Additionally, a buzzer will sound.
– Press and hold the brake pedal ⇒ 
.
– Apply the handbrake.
– Move the selector lever to position P.
Holding the car on a hill
– Always apply the brake pedal firmly to prevent the vehicle from
“moving backwards; if necessary, apply the handbrake” ⇒ 
.
Do not try to stop the vehicle “rolling back” by increasing the
engine speed when a gear is engaged (pressing the accelera-
tor) ⇒ 
.
Moving off uphill in vehicles without Hill start assistant*
– Apply the handbrake.
– Once you have engaged a gear press the accelerator carefully
and disengage the handbrake.
Moving off uphill in vehicles without Hill start assistant*
– Once you have engaged a gear, release the footbrake and press
the accelerator ⇒ page 148, Hill hold assist*.
Driving down hills: In some situations (on mountain roads or when towing a
trailer or caravan) it can be advantageous to switch temporarily to the man-
ual gearbox programme so that the gear ratios can be selected manually to
suit the driving conditions ⇒ 
. On level ground it is sufficient to move the selector lever to position P. On
slopes, first engage the parking brake and then put the selection lever into
the P position. This avoids overloading the locking mechanism and it will be
easier to move the selector lever from position P.
WARNING
● As a driver you should never leave your vehicle if the engine is run-
ning and a gear is engaged. If you have to leave your vehicle while the
engine is running, you must apply the handbrake and engage the parking
lock P.
● If the engine is running and a gear is engaged (D/S or R) or the vehi-
cle is in tiptronic mode, you will need to hold the car with the footbrake.
Otherwise, the car will creep forwards as the power transmission is not
fully interrupted even when the engine is idling.
● Take care not to accidentally press the accelerator pedal when the ve-
hicle is stopped. The vehicle could otherwise start moving immediately
(in some cases even if the parking brake is engaged) resulting in the risk
of an accident.
● While you are selecting a gear and the vehicle is stopped with the en-
gine running, do not accelerate. Failure to do so could result in an acci-
dent.
● Never move the selector lever to R or P when driving: this could result
in an accident!
● Before you drive down a steep gradient, reduce your speed and use
tiptronic to select a low gear.
● Never allow the brake to rub and do not use the brake pedal too often
or for long periods. Constant braking causes overheating in the brakes.
This could significantly reduce braking power, increase braking distance
or even result in the total failure of the brake system.
● To avoid rolling back on gradients always hold the vehicle with the
footbrake or handbrake if you have to stop. 
