Driving
– With a selected gear, accelerate slowly and at the same time,
release the handbrake.
The steeper the slope, the lower the needed gear. This increases the brak-
ing effect of the engine. For example, when driving down a very steep slope
in third gear. If the engine brake effect is not enough, the vehicle will speed
up. The automatic gearbox automatically changes up to prevent the engine
over-revving. Use the foot brake to reduce speed and change into third gear
again using Tiptronic* ⇒
.
Your vehicle has an automatic interlock which prevents the selector lever
from being put into a position for driving forwards or in reverse from posi-
tions P or N if the brake pedal is not depressed.
The ignition key cannot be removed unless the selector lever is in position
P.
Warning lamp “Pressing brake pedal”
When the warning lamp next to the selector lever lights up, press the brake
pedal. This is necessary when the automatic gearbox selector lever is
moved out of positions P or N. At the same time, a text message or the in-
structions to perform necessary operations may appear on the instrument
panel.
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 parking brake and put the selector
lever in position P.
● If the engine is running and D or R are engaged, you will need to hold
vehicle stopped by depressing the brake pedal. The car would keep on
creeping forward as the power transmission is not fully interrupted even
when the engine is idling.
WARNING (Continued)
● Never accelerate when moving the selector gear or you may cause an
accident.
● Never move the selector lever to R or P when driving. Risk of accident!
● Before driving down a long, steep slope, it is advisable to reduce
speed and change into a lower gear.
● If you stop the vehicle up hill, always hold the foot brake strongly de-
pressed down to stop it from rolling back.
● Never allow the brake to rub and do not use the brake pedal too often
or for long periods. Constant braking will cause the brakes to overheat
and will considerably reduce the brake effect. This increases the braking
distance and could cause the brake system to fail.
● Never allow the car to roll down a mountain or a slope with the lever
in the N or D position, regardless of the engine is running or not.
CAUTION
● If you stop the vehicle up hills, do not attempt to stop it from rolling
back by depressing the accelerator when a gear has been selected. Other-
wise, the automatic gearbox may overheat causing damage. Pull the hand-
brake up or fully depress the brake pedal to prevent the vehicle from rolling
away.
● If you allow the car to roll when the engine is not running, or with the
selector lever in position N, a lack of lubrication in the automatic gearbox
will damage it.

The selected gear is displayed on the side of the selector lever and on the
instrument panel screen. The currently selected gear for the automatic gear-
box will also be shown on the display.
Tiptronic gear indicator
If the automatic gearbox is shifted manually, the selected gears are shown
on the screen.
P - parking lock
When the selector lever is in this position, the drive wheels are locked me-
chanically.
Position P on the lever must only be selected if the vehicle is stationary.
To move selector lever from position P, the locking button on the selector
lever handle must be pressed and the brake pedal depressed at the same
time while the ignition is switched on.
To put the selector lever in position
P, simply press the lock button down
and, if necessary, depress the brake pedal down.
R - Reverse gear
The reverse gear is engaged in this position.
Reverse gear must be engaged only when the vehicle is stationary and the
engine is idling.
To move the selector lever to position R, press the lock button down and, at
the same time, press the brake pedal down, with the ignition switched on.
With the selector lever in position R and the ignition switched on the follow-
ing occurs:
● Reverse lights light up.
● The air conditioner automatically changes the air recirculation mode.

Always apply the handbrake when you leave your vehicle and when
you park.
Applying the handbrake
–Pull the handbrake lever up firmly ⇒ fig. 119.
Releasing the handbrake
– Pull the lever up slightly and press the release knob in the di-
rection of the arrow ⇒ fig. 119 and guide the handbrake lever
down fully ⇒
.
Always apply the handbrake as far as it will go in order to prevent you from
driving with the handbrake applied by mistake ⇒
.
The handbrake warning lamp lights up when the handbrake is applied
and the ignition switched on. The warning turns off when the handbrake is
released.
WARNING
● Never use the handbrake to stop the vehicle when it is in motion. The
braking distance is considerably longer, because braking is only applied
to the rear wheels. Risk of accident!
● If it is only partially released, this will cause rear brakes overheating,
which can impair the function of the brake system and could lead to an
accident. This also causes premature wear on the rear brake pads.
CAUTION
Always apply the handbrake before you leave the vehicle. The first gear
should also be selected. Parking
The handbrake should always be firmly applied when the
vehicle is parked.
Always note the following points when parking the vehicle:
–
Use the brake pedal to stop the vehicle.
– Apply the handbrake.
– Select first gear.
– Switch the engine off and remove the key from the ignition. Turn
the steering wheel slightly to engage the steering lock.
– Always take you car keys with you when you leave the vehicle
⇒
.
Additional notes on parking the vehicle on gradients:
Turn the steering wheel so that the vehicle rolls against the kerb if it started
to roll.
● If the vehicle is parked facing downhill, turn the front wheels so that
they point towards the kerb .
● If the vehicle is parked facing uphill, turn the front wheels so that they
point away from the kerb .
● Secure the vehicle as normal by applying the handbrake firmly and se-
lecting first gear.

Driving
● External ultra-sonic sources (pneumatic drills, construction machinery,
other vehicles with PDC) may interfere with the operation of the system.
● Periodic cleaning of the sensors, take care not to damage or scratch
them. When cleaning with high pressure washers or steam cleaners, the
sensors should be sprayed for only a very short period and from a distance
of more than 10 cm.
Cruise speed* (Cruise control system)
Description
The cruise control system is able to maintain the set speed
in the range of 30 km/h to 180 km/h. Once the speed setting has been saved, you may take your foot off the ac-
celerator.
WARNING
It could be dangerous to use the cruise control system if it is not possible
to drive at constant speed.
● Do not use the cruise control system when driving in dense traffic, on
roads with lots of bends or on roads with poor conditions (with ice, slip-
pery surfaces, loose grit or gravel), as this could cause an accident.
● Always switch the cruise control system off after using it in order to
avoid an involuntary use.
● It is dangerous to use a set speed which is too high for the current
road, traffic or weather conditions. Risk of accident.
Note
The cruise control cannot maintain a constant speed when descending
downhill. The vehicle will accelerate due to its own weight. Use the foot
brake to slow the vehicle.

Brakes Brake servo
The brake servo increases the pressure you apply to the brake pedal. It
works only when the engine is running .
If the brake servo is not functioning due to a malfunction, or if the vehicle
has to be towed, you will have to press the brake pedal considerably harder
to make up for the lack of servo assistance.
WARNING
The braking distance can also be affected by external factors.
● Never let the vehicle coast with the engine switched off. Failure to do
so could result in an accident. The braking distance is increased consid-
erably when the brake servo is not active.
● If the brake servo is not working, for example when the vehicle is be-
ing towed, you will have to press the brake pedal considerably harder
than normal.
Hydraulic Brake Assist (HBA)*
The Hydraulic Brake Assist function (HBA) is only included in
vehicles with ESP.
In an emergency, most drivers brake in time, but not with maximum force.
This results in unnecessarily long braking distances.
This is when the brake assist system comes into action. When pressing the
brake pedal rapidly, the assistant interprets it as an emergency. It then very
quickly builds up the full brake pressure so that the ABS can be activated
more quickly and efficiently, thus reducing the braking distance.
Do not reduce the pressure on the brake pedal. The brake assist system
switches off automatically as soon as you release the brake.
Automatic hazard warning lights activation
The brake lights flash automatically to indicate that the vehicle is braking
suddenly or in an emergency situation. If the emergency braking continues
until the vehicle comes to a standstill, the hazard warning lights will then
come on and the brake lights will remain on permanently from that moment.
The warning lights will automatically switch off when the vehicle begins to
move again or when the "warning" light button is pressed.

Electronic Stability Programme (ESP)*
ESP reduces the danger of skidding by braking the wheels individually.
The system uses the steering wheel angle and road speed to calculate the
changes of direction desired by the driver, and constantly compares them
with the actual behaviour of the vehicle. If the desired course is not being
maintained (for instance, if the vehicle is starting to skid), then the ESP
compensates automatically by braking the appropriate wheel.
The forces acting on the braked wheel bring the vehicle back to a stable
condition. If the vehicle tends to oversteer, the system will act on the front
wheel on the outside of the turn.
WARNING
● It must be remembered that ESP cannot defy the laws of physics. This
should be kept in mind, particularly on slippery and wet roads and when
towing a trailer.
● Always adapt your driving style to suit the condition of the roads and
the traffic situation. Do not let the extra safety afforded by ESP tempt you
into taking any risks when driving, as this can cause accidents.
CAUTION
● In order to ensure that ESP functions correctly, all four wheels must be
fitted with the same tyres. Any differences in the rolling radius of the tyres
can cause the system to reduce engine power when this is not desired.
● Modifications to the vehicle (e.g. to the engine, the brake system, run-
ning gear or any components affecting the wheels and tyres) could affect
the efficiency of the ABS, EDL, ESP and TCS. Anti-lock brake system (ABS)
The anti-lock brake system prevents the wheels locking during braking
⇒ page 168.
Electronic differential lock (EDL)*
The electronic differential lock helps prevent the loss of trac-
tion caused if one of the driven wheels starts spinning.
EDL helps the vehicle to start moving, accelerate and climb a gradient in
slippery conditions where this may otherwise be difficult or even impossi-
ble.
The system will control the revolutions of the drive wheels using the ABS
sensors (in case of an EDL fault the warning lamp for ABS lights up)
⇒ page 69.
At speeds of up to approximately 80 km/h, it is able to balance out differen-
ces in the speed of the driven wheels of approximately 100 rpm caused by a
slippery road surface on one side of the vehicle. It does this by braking the
wheel which has lost traction and distributing more driving force to the oth-
er driven wheel via the differential.
To prevent the disc brake of the braking wheel from overheating, the EDL
cuts out automatically if subjected to excessive loads. The vehicle will con-
tinue to function normally without EDL. For this reason, the driver is not in-
formed that the EDL has been switched off.
The EDL will switch on again automatically when the brake has cooled
down.
