Driving
● If in an increase in airflow 10
⇒ fig. 113 is required for more than three
presses.
● Temperature setting HI or LO is selected.
● The engine coolant temperature is insufficient.
● The alternator is faulty, for example the V-belt has ruptured.
● If any of the conditions described in the previous section are not fulfil-
led.
WARNING
Never allow the vehicle to move with the engine off for any reason. You
could lose control of your vehicle. This could cause an accident and seri-
ous injury.
● 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.
● Disconnect the Start-Stop system when driving through water (ford-
ing streams, etc.).
Note
● For vehicles with the Start-Stop function and a manual gearbox, when
the engine is started, the clutch must be pressed.
● When the conditions for the Start-Stop function are not fulfilled, the in-
strument panel displays the Start-Stop indicator dimmed.
● If the steering wheel is turned more than 270°, it will not be possible to
start the vehicle again. To start the vehicle, straighten the steering wheel so
that it is turned less than 270°. Activating and deactivating the Start-Stop function

manual gearbox Engaging the reverse gear
–
The vehicle should be stationary with the engine idling. Press
the clutch down thoroughly.
– Place the gear lever into neutral and push the lever downwards.
– Slide the gear lever to the left, and then into the reverse posi-
tion shown on the gear lever.
The reverse gear can only be engaged when the vehicle is stationary. When
the engine is running and before engaging this gear, wait about 6 seconds
with the clutch pressed down thoroughly in order to protect the gearbox.
The reverse lights light up when the reverse gear is selected and the igni-
tion is on.
WARNING
● When the engine is running, the vehicle will start to move as soon as
a gear is engaged and the clutch released.
● Never select the reverse gear when the vehicle is in motion. Risk of
accident.
Note
● Do not rest your hand on the gear lever while driving. The pressure of
your hand could cause premature wear on the selector forks in the gearbox.
● When changing gear, you should always depress the clutch fully to
avoid unnecessary wear and damage.
● Do not hold the car “on the clutch” on hills. This causes premature wear
and damage to the clutch.
● Do not leave your foot on the clutch pedal; although the pressure may
seem insignificant, it can cause the premature wear of the clutch plate. Use
the foot rest when you do not need to change gear. 

170Driving
–Press the button on the selector lever knob (on the left)
⇒ fig. 126.
– 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 the vehicle
– 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. 

Driving
Handbrake Using the handbrake
The handbrake should be applied firmly to prevent the vehi-
cle from accidentally rolling away.
Fig. 129 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. 129.
Releasing the handbrake
– Pull the lever up slightly and press the release knob in the di-
rection of the arrow ⇒ fig. 129 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.
If you drive faster than 6 km/h with the handbrake on, the following mes-
sage* will appear on the instrument panel display: HANDBRAKE ON. You will
also hear an acoustic warning signal.
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. 

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 Hydraulic Brake Assist function (HBA) is only included in
vehicles with ESC (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.
Emergency braking warning
If the vehicle is braked suddenly and continuously at a speed of more than
80 km/h, 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 au-
tomatically when the vehicle starts to move again. 

184Intelligent technology
The ASR (TCS) is connected automatically when the engine starts. If neces-
sary, it may be turned on or off pushing the button on the centre console.
When the ASR (TCS) is disconnected, the warning lamp  OFF
lights up. The
TCS should normally be left on. Only in exceptional circumstances, when the
slipping of the wheels is required, should it be disconnected, for example
● With compact temporary spare wheel.
● When using the snow chains.
● When driving in deep snow or on soft terrain.
● When the vehicle is bogged-down, to free it by rocking.
The TCS should be switched on again as soon as possible.
WARNING
● Remember that the ASR (TCS) 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 ASR (TCS)
tempt you into taking any risks when driving.
CAUTION
● To ensure that the ASR (TCS) 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 and ASR (TCS). 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.
By using the ESC (ESP) sensors and signals, the XDS system is able to de-
tect and correct this effect.
Through the ESC (ESP), the XDS brakes the inner wheel, thereby counteract-
ing the excess drive torque in this wheel. This means that the driver's de-
sired trajectory is much more precise,
The XDS system operates in combination with the ESC (ESP) and is always
active, even when the traction control ASR (TCS) is disconnected.

Electronic Stability Control ESC (ESP) *
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 (ESP) includes the ABS, EDL, ASR (TCS)
and Steering manoeuvre recommendations. 

185
Intelligent technology
Electronic Stability Control ESC (ESP)*
The ESC (ESP) reduces the danger of skidding by braking the wheels indi-
vidually.
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 ESC
(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.
Steering manoeuvre recommendations
This is a complementary safety function included in the ESC (ESP). This
function aids the driver to better stabilize the vehicle in a critical situation.
For example, in case of sudden braking surface with varied adherence, the
vehicle will tend to destabilise its trajectory to the right or to the left. In this
case the ESC (ESP) recognises the situation and helps the driver with a
counter steering manoeuvre from the power steering.
This function simply provides the driver with a recommended manoeuvre in
critical situations.
The vehicle does not steer itself with this function, the driver has full control
of the vehicle at all times.
WARNING
● Remember that ESC (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 ESC (ESP)
tempt you into taking any risks when driving.
CAUTION
● To ensure that the ESC (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, ESC (ESP) and ASR (TCS). 
Anti-lock brake system (ABS)
The anti-lock brake system prevents the wheels locking during braking
⇒ page 183. 
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 84.
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. 

If and when
– All passengers should leave the vehicle. They should wait in a
safe area (for instance behind the roadside crash barrier).
– Switch off the engine. Switch on the hazard warning lights.
– Apply the handbrake firmly.
– Engage the first gear , or put the selector lever to position P for
those vehicles with an automatic gearbox.
– If you are towing a trailer, unhitch it from your vehicle.
– Take the vehicle tools and the spare wheel out of the luggage
compartment.
WARNING
Put the hazard warning lights on and place the warning triangle in posi-
tion. This is for your own safety and also warns other road users.
CAUTION
If you have to change the wheel on a gradient, block the wheel opposite the
wheel being changed by placing a stone or similar object under it to prevent
the vehicle from rolling away.
Note
Please observe legal requirements when doing so. 
Changing a wheel
Change the wheel as described below
– Pull off the hub cap. See ⇒ fig. 155. –
Slacken the wheel bolts.
– Raise the car with the jack at the corresponding point.
– Remove the wheel and then mount the spare wheel
– Lower the vehicle.
– Tighten the wheel bolts firmly with the box spanner.
– Replace the wheel trim. 
After changing a wheel
After changing the wheel there are still tasks to complete. – Put the tools and jack back in the luggage compartment.
– Place the wheel with the defective tyre in the luggage compart-
ment and secure it.
– Check the tyre pressure of the newly fitted tyre as soon as pos-
sible.
– Have the tightening torque of the wheel bolts checked as soon
as possible with a torque wrench. The prescribed torque must
be 120 Nm.
Note
● If you notice that the wheel bolts are corroded and difficult to turn when
changing a wheel, they must be replaced before having the wheel bolt tor-
que checked.
● For safety reasons, drive at moderate speeds until the wheel bolt tight-
ening torque has been checked. 
