Driving
Stopping briefly
– If stopping for a short time, keep the vehicle stationary by
pressing the foot brake hard to prevent the vehicle moving
backwards on a slope or “creeping” forwards, e.g. at traffic
lights. The selector lever does not need to be put into the posi-
tions P or N.
– Do not press the accelerator.
Parking
– Press and hold the brake pedal until the vehicle comes to a
standstill ⇒
.
– Apply the handbrake.
– By pressing the lock button down, move the selector lever to P
and release the lock button.
Driving up and down hills
– Press the selector lever from position “D” to the right into the
tiptronic selector gate.
– Lightly press the selector lever back to change down.
Holding the car on a hill
– The brake must be always pressed down to prevent the vehicle
from “rolling backwards” ⇒
. Do not try to prevent the vehicle
from rolling backwards by increasing the engine speed while a
range of gears is selected.
Starting the vehicle up hills
– Apply the handbrake. –
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 3rd gear
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.
Control 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. A text message or instructions 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 range is engaged. If you have to leave your vehicle while
the engine is running, you must apply the parking brake and put the se-
lector 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 vehicle would keep
on creeping forward as the power transmission is not fully interrupted
even when the engine is idling.

Selector lever positions
The selected gear is displayed on the side of the selector lever and on the
instrument panel display. The currently selected gear for the automatic
gearbox 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 driven 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. ●
The wiper starts if the windscreen washer is on.
● The parking distance warning system* switches on.
N - Neutral (idling)
If this position is selected, the gearbox is in neutral. Power is not transmit-
ted to the wheels and the engine does not have a braking function.
Never use the N position to drive down a long hill. There is no engine brak-
ing and the brakes are subjected to excessive stain.
You could damage the automatic gearbox if you drive down hills with the
gearbox lever in position N and the engine switched off.
D - Drive (forward)
In this position the gearbox automatically changes to a lower or higher gear,
according to the engine's requirements, the driving style and speed. The
braking effect of the engine when driving downhill is very limited when the
selector is in this position. The instrument panel display shows the selected
gear as well as the selector lever in position D.
If position N has been selected and you wish to select D, you must press the
foot brake if the vehicle is stationary, or travelling at under 5 km/h (3 mph).
S - Standard driving position (Sport programme)
When the selector lever is in position S, it will automatically change up into
a higher gear later, and change down into a low gear, if compared with posi-
tion D. This way, it is possible to take full advantage of the engine reserve
power, depending on the engine demand, driving style and speed. The
braking effect of the engine when driving downhill is very limited. On the
instrument panel display the selected gear is shown as well as the selector
lever to position S.
To select gear range S, press the lock button on the selector lever.

Driving
WARNING
If the vehicle moves with no control, an accident and serious injury may
occur.
● As a driver, you should never leave your vehicle if the engine is run-
ning and a gear range is engaged. If you have to leave your vehicle while
the engine is running, you must always apply the handbrake and engage
the parking lock position P.
● With the engine running and D or R engaged, you must hold the vehi-
cle stopped by pressing the brake pedal. Even while idling, the power
transmission is not fully interrupted and the vehicle could keep moving
forward.
● Never accelerate when moving the selector lever or you may cause an
accident.
● Never move the selector lever to “R” or “P” when driving. Risk of acci-
dent.
● Before driving down a very steep slope, reduce your speed and shift
to first gear.
● Always hold the vehicle on the foot brake if you stop on hills. Other-
wise, the vehicle could roll 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.
WARNING
Never switch the engine off until the vehicle is stationary. You could lose
control of your vehicle. This could cause an accident and serious injury.
● The airbags and belt tensioners do not work when the ignition is
switched off.
WARNING (Continued)
● The brake servo does not work with the engine off. You need more
force to stop the vehicle.
● Power steering does not work when the engine is not running. That is
why it is much more difficult to turn the steering wheel.
● Never remove the key from the ignition if the vehicle is in motion. The
steering lock could suddenly engage, and you would not be able to steer
the vehicle.
● Never allow the vehicle to roll downhill with the selector lever in “N”,
regardless of whether the engine is running or not.
CAUTION
If you allow the vehicle to move when the engine is switched off or with the
selector lever in position “N”, take your foot off the accelerator and wait un-
til the engine starts idling before returning to position “D”.
Gear-change indicator
The recommended gear for saving fuel is indicated on the dash screen of
certain vehicles during driving.

The optimal gear is selected.
Changing to a higher gear is recommended.
Changing to a lower gear is recommended.

Driving
Always apply the handbrake when you leave your vehicle and when
you park.
Applying the handbrake
– Pull the handbrake lever up firmly ⇒ Fig. 122.
Releasing the handbrake
– Pull the lever up slightly and press the release knob in the di-
rection of the arrow ⇒ Fig. 122 and guide the handbrake lever
down fully ⇒
.
Always apply the handbrake as far as it will go in order to prevent yourself
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 lamp turns off when the hand-
brake 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 the handbrake is only partially released, this will cause the rear
brakes to overheat, 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 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.

WARNING
● Take measures to reduce the risk of injury when you leave your vehi-
cle unattended.
● Never park where the hot exhaust system could ignite inflammable
materials, such as dry grass, low bushes, spilt fuel etc.
● Never allow vehicle occupants to remain in the vehicle when it is
locked. They would be unable to open the vehicle from the inside, and
could become trapped in the vehicle in an emergency. In the event of an
emergency, locked doors will delay assistance to vehicle occupants.
● Never leave children alone in the vehicle. They could set the vehicle
in motion, for example, by releasing the handbrake or the gearbox lever.
● Depending on weather conditions, it may become extremely hot or
cold inside the vehicle. This can be fatal.
Hill driving assistant*
This function is only included in vehicles with ESC. The hill driving assistant helps the driver to move off and upwards on a hill
when the vehicle is stationary.
The system maintains brake pressure for approximately two seconds after
the driver takes his foot off the brake pedal to prevent the vehicle from
lurching backwards when it is started. During these two seconds, the driver
has enough time to release the clutch pedal and accelerate without the ve-
hicle moving and without having to use the handbrake, making start-up
easier, more comfortable and safer.
These are the basic operation conditions:
● being on a ramp or hill/slope,
● closed doors,
● vehicle completely stationary, ●
engine running and foot on the brake,
● besides having a gear engaged or being in neutral for manual gear
change and with the selector lever at positions S, D or R in vehicles with au-
tomatic gearbox.
This system is also active in reversing uphill.
WARNING
● If you do not start the vehicle immediately after taking your foot off
the brake pedal, the vehicle may start to roll back under certain condi-
tions. Depress the brake pedal or use the hand brake immediately.
● If the engine stalls, depress the brake pedal or use the hand brake
immediately.
● When following a line of traffic uphill, if you want to prevent the vehi-
cle from rolling back accidentally when starting off, hold the brake pedal
down for a few seconds before starting off.
Note
The Official Service or a specialist workshop can tell you if your vehicle is
equipped with this system.
Parking aid* General information
Various aid systems are in place to help in parking and manoeuvring de-
pending on the vehicle’s equipment:
The rear parking aid is an audible aid that warns against obstacles behind
the vehicle ⇒ page 167.

WARNING
● The risk of accident is higher if you drive too fast, if you do not keep
your distance to the vehicle in front, and when the road surface is slip-
pery or wet. The increased accident risk cannot be reduced by the brake
assist system.
● The brake assist system cannot defy the laws of physics. Slippery
and wet roads are dangerous even with the brake assist system! There-
fore, it is essential that you adjust your speed to suit the road and traffic
conditions. Do not let the extra safety features tempt you into taking any
risks when driving.
Anti-lock brake system and traction control
ABS Anti-lock brake system (ABS)
The anti-lock brake system prevents the wheels locking dur-
ing braking.
The anti-lock brake system (ABS) is an important part of the vehicle's active
safety system.
How the ABS works
If one of the wheels is turns too slowly in relation to the road speed, and is
close to locking, the system will reduce the braking pressure for this wheel.
The driver is made aware of this control process by a pulsating of the brake
pedal and audible noise. This is a deliberate warning to the driver that one
or more of the wheels is tending to lock and the ABS control function has
intervened. In this situation it is important to keep the brake pedal fully de-
pressed so the ABS can regulate the brake application. Do not “pump”. If you brake hard on a slippery road surface, the best possible control is re-
tained as the wheels do not lock.
However, ABS will not necessarily guarantee shorter braking distances in
all
conditions. The braking distance could even be longer if you brake on gravel
or on fresh snow covering a slippery surface.
WARNING
● The anti-lock brake system cannot defy the laws of physics. Slippery
and wet roads are dangerous even with ABS! If you notice that the ABS is
working (to counteract locked wheels under braking), you should reduce
speed immediately to suit the road and traffic conditions. Do not let the
extra safety features tempt you into taking any risks when driving.
● The effectiveness of ABS is also determined by the tyres fitted
⇒ page 222.
● If the running gear or brake system is modified, the effectiveness of
the ABS could be severely limited.
Traction control system (ASR)*
The traction control system prevents the driven wheels from
spinning when the vehicle is accelerating. The system al-
ways includes ABS
Description and operation of the traction control system during
acceleration (ASR
On front-wheel drive vehicles, the ASR system intervenes, reducing engine
power and preventing the driven wheels from slipping during acceleration.
The system works in the entire speed range in conjunction with ABS. If a
failure occurs in the ABS, the ASR will also stop working.
Safety FirstOperating instructionsPractical TipsTechnical Specifications

Intelligent technology
Electronic Stability Control (ESC)*
The ESC reduces the risk 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. When irregularities occur, for exam-
ple, if the vehicle begins to skid, the ESC brakes the appropriate wheel au-
tomatically.
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
● Remember that not even the ESC can 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. The greater safety provided by the ESC should not
encourage you to run any risks.
CAUTION
● To ensure that the ESC works 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.
● Any modifications made to the vehicle (for example, to the engine,
brake system, running gear or to the combination of wheels and tyres) may
affect the operation of the ABS, EDL, ESC and ASR. Anti-lock brake system (ABS)
The anti-lock brake system prevents the wheels locking during braking
⇒ page 175
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 driven wheels using the ABS
sensors (in case of an EDL fault the warning lamp for ABS lights up)
⇒ page 71.
At speeds of up to approximately 80 km/h (50 mph), it is able to balance
out differences 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 other 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.

186Driving and the environment
WARNING
The towing bracket ball coupling must be stored securely in the luggage
compartment to prevent them being flung through the vehicle and caus-
ing injury.
Note
● By law, the ball coupling must be removed if a trailer is not being towed
if it obscures the number plate.
Driving tips
Driving with a trailer always requires extra care. Weight distribution
The weight distribution of a loaded trailer with an unladen vehicle is very
unfavourable. However, if this cannot be avoided, drive extra slowly to allow
for the unbalanced weight distribution.
Speed
The stability of the vehicle and trailer is reduced with increasing speed. For
this reason, it is advisable not to drive at the maximum permissible speed
in an unfavourable road, weather or wind conditions. This applies especially
when driving downhill.
You should always reduce speed immediately if the trailer shows the slight-
est sign of snaking. Never try to stop the “snaking” by increasing speed.
Always brake in due course. If the trailer has an overrun brake, apply the
brakes gently at first and then, firmly. This will prevent the jerking that can
be caused by locking of trailer wheels. Select a low gear in due course be-
fore going down a steep downhill. This enables you to use the engine brak-
ing to slow down the vehicle. Reheating
At very high temperatures and during prolonged slopes, driving in a low
gear and high engine speed, always monitor if the excessive coolant tem-
perature gauge is activated
⇒ page 75.
Electronic Stability Control*
The ESC* system helps to stabilise the trailer in case of skidding or rocking.
