Driving
– Select a gear for driving ( R, D or S).
– Release the button and wait a few seconds for the gear to en-
gage, a light jerk will be felt.
– Release the brake and accelerate.
Short stop
– Hold the vehicle stationary with the brake pressed down (for ex-
ample at traffic lights). The selector lever does not need to be
put into the positions P or N for this.
– Do not press the accelerator.
Parking
– Press the brake pedal and hold to bring the vehicle to a stop.
– Apply the handbrake firmly.
– Press in the button on the selector lever knob, move the lever to
the position P and release the button.
Driving slowly
– Move the selector lever to position D and press to the right to
put the lever into tiptronic mode.
– Press the gear lever towards (-) to select a lower gear.
Hill stop
– Hold the vehicle, in all cases, using the brake pedal to prevent
rolling back.
– Do not try to slow the vehicle using another forward gear (en-
gine braking). Descending gradients
–
With the gear engaged, release the brake and accelerate.
The steeper the gradient the lower the gear must be for effective engine
braking. For example, if 3rd gear is used on a very steep gradient, the en-
gine braking is insufficient and vehicle accelerates. So that the engine
speed does not become excessive, the gearbox changes to the next highest
gear. Depress the brake pedal and move the selector lever to the tiptronic
gate to return to 3rd gear.
WARNING
● The driver should never leave the vehicle while the engine is running
or with any gear selected. If for any reason you must leave the vehicle
with the engine running, apply the handbrake and move the selector lev-
er to position P.
● When the engine is running and the positions D, S or R are selected,
it is necessary to hold the vehicle with the brake pedal because the vehi-
cle will creep at a low speed.
● Never accelerate while changing the position of the gear lever (risk of
an accident).
● The gear lever must never be moved into the positions R or P while
moving (risk of an accident).
● Before descending a steep gradient, reduce speed and use the tip-
tronic programme to select a lower gear.
● If you must stop on a hill, always hold the vehicle using the footbrake
to avoid rolling back.

WARNING (Continued)
● The footbrake must not be held for a long period of time, not even
lightly; continuous braking will cause overheating of the brakes and a re-
duction or even a loss of braking power and a significant increase in
braking distances.
● Never allow the vehicle to coast down a gradient with the selector lev-
er in positions N or D, even when the engine is not running. For descents,
the use of the tiptronic programme is recommended to keep the speed
reduced.
CAUTION
● Never use the automatic gearbox to hold the vehicle stationary on a hill,
even for short periods, as this may overheat the gearbox and cause dam-
age. Apply the handbrake or depress the foot brake to hold the vehicle in
position.
● If the vehicle is allowed to roll with the engine stopped but the selector
in position N then the gearbox may be damaged because it will not be lubri-
cated. Changing gear in tiptronic mode*

Handbrake
Using the handbrake
The handbrake should be applied firmly to prevent the vehi-
cle from accidentally rolling away.
Fig. 152 Handbrake be-
tween the front seats
Always apply the handbrake when you leave your vehicle and when
you park.
Applying the handbrake
– Pull the handbrake lever up firmly ⇒ Fig. 152.
Releasing the handbrake
– Pull the lever up slightly and press the release knob in the di-
rection of the arrow ⇒ Fig. 152 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.
If you drive faster than 6 km/h (4 mph) with the handbrake on, the following
message* will appear on the instrument panel display: HANDBRAKE ON. You
will also hear an audible warning.
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.
189
Driving
– 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.

Cruise speed* (Cruise control system)
Description
The CCS is able to maintain the set speed in the range from
approx. 30 km/h (19 mph) to 180 km/h (112 mph). 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 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. Switching the cruise control system on and off

– Press the lower part SET/- of the rocker switch ⇒ Fig. 155 A
once briefly when you have reached the speed you wish to set.
When you release the rocker switch, the current speed is set and held con-
stant.
Adjusting set speed*
The speed can be altered without touching the accelerator or
the brake. Setting a higher speed
– Press the upper part RES/+ of the rocker switch ⇒ Fig. 155 A
to
increase the speed. The vehicle will continue to accelerate as
long as you keep the rocker switch pressed. When you release
the switch, the new speed is stored. Setting a lower speed
–
Press the lower part SET/– ⇒ Fig. 155 A
of the rocker switch to
reduce the speed. The vehicle will automatically reduce its
speed for as long as you keep the switch pressed. When you re-
lease the switch, the new speed is stored.
When you increase speed with the accelerator and then release the pedal,
the system will automatically restore the set speed. This will not be the
case, however, if the vehicle speed is more than 10 km/h (6 mph) higher
than the stored speed for longer than 5 minutes. The speed will have to be
stored again.
Cruise control is switched off if you reduce speed by depressing the brake
pedal. You can reactivate the control by pressing once on the upper part of
the rocker switch RES/+ ⇒ Fig. 155 A

Practical Tips
Intelligent technology
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 function (Hydraulic Brake Assist HBA) is only included in
vehicles with ESC.
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.
Emergency braking warning
If the vehicle is braked suddenly and continuously at a speed of more than
80 km/h (50 mph), the brake light flashes several times per second to warn
vehicles driving behind. If you continue braking, the hazard warning lights
will come on automatically when the vehicle comes to a standstill. They
switch off automatically when the vehicle starts to move again.
198Intelligent technology
The ASR automatically switches on when the engine is started. If necessary,
it may be turned on or off by briefly pushing the button on the centre con-
sole.
When the ASR is switched off, the OFF
warning lamp will light up. The ASR
should normally be left on. Only in exceptional circumstances, when the
slipping of the wheels is required, it will be necessary to have it disconnec-
ted, for example.
● With compact temporary spare wheel.
● When using the snow chains.
● When driving in deep snow or on loose surfaces
● When the vehicle is bogged-down, to free it by rocking.
The ASR should be switched on again as soon as possible.
WARNING
● Remember that not even the ASR 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 ASR should not
encourage you to run any risks.
CAUTION
● To ensure that the ASR works correctly, identical tyres should be fitted
on all four wheels. 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 and ASR. XDS*
Driveshaft differential
When taking a bend, the driveshaft differential mechanism allows the outer
wheel to turn at a higher speed than the inner wheel. In this way, the wheel
that is turning faster (outer wheel) receives less drive torque than the inner
wheel. This may mean that in certain situations the torque delivered to the
inner wheel is too high, causing the wheels to spin. On the other hand, the
outer wheel is receiving a lower drive torque than it could transmit. This
causes an overall loss of lateral grip on the front axle, resulting in under-
steer or “lengthening” of the trajectory.
The XDS system can detect and correct this effect via the sensors and sig-
nals of the ESC.
Via the ESC, the XDS will brake the inside wheel and counter the excess
driving torque of that wheel. This means that the driver's desired trajectory
is much more precise,
The XDS system works in combination with the ESC and is always active,
even when the ASR traction control is disconnected.
Electronic Stability Control (ESC)*
General notes
The Electronic Stability Control increases the vehicle's stabil-
ity on the road. The Electronic Stability Control helps reduce the danger of skidding.
The Electronic Stability Control (ESC) includes the ABS, EDL, ASR and Steer-
ing manoeuvre recommendation systems.
