Starting the vehicle
– Press and hold the brake pedal.
– Press and hold the interlock button (the button on the selector
lever handle), move the selector lever to the required position,
for instance D, 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). –
To prevent the vehicle from rolling away, apply the parking
brake before moving off on steep gradients ⇒
.
Parking the vehicle
– Press and hold the brake pedal ⇒
.
– Apply the parking brake.
– Press and hold the interlock button, move the selector lever to P
and release the interlock button.
The engine can only be started when the selector lever is at P or N.
On level ground it is sufficient to move the selector lever to 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 eas-
ier to move the selector lever from position P.
Vehicles with multitronic® gearbox: Your vehicle is equipped with the hill
hold assist function which makes it easier to start off on a slope. The sys-
tem is activated when you press and hold the brake pedal for a few sec-
onds. When you release the brake pedal the braking force will be main-
tained for a short moment in order to prevent the vehicle rolling back when
you drive away.
WARNING
● 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.
● Please note that some power will still be transmitted when you stop
temporarily with the selector lever in position D, S or R. Therefore, when
stopping you will need to press the brake with the force required to hold
the vehicle still. Failure to do so could result in an accident.
● Never move the selector lever to R or P when driving, as this could
cause an accident.

WARNING (Continued)
to “creep”. The throttle must on no account be opened inadvertently (for
instance by hand from the engine compartment) when a gear is engaged
with the vehicle stationary. The vehicle could otherwise start moving im-
mediately (in some cases even if the parking brake is engaged) and pos-
sibly cause an accident.
● To avoid accidents, apply the parking brake and put the selector lever
in position P before opening the bonnet and working on the vehicle with
the engine running. Please observe the important safety warnings
⇒ page 227, Work in the engine compartment.
Note
● Applies to vehicles with tiptronic gearbox:
● If the lever is moved accidentally to N when driving, release the accelera-
tor and let the engine speed drop to idling before selecting D or S again.
● For the sake of fuel economy (and the environment), the gearbox ratios
on some models are designed so that maximum speed is only obtained
when the gear lever is in position S. Selector lever lock
The selector lever lock prevents gears from being engaged
inadvertently, so that the vehicle is not set in motion unin-
tentionally.

Driving
Vehicles with multitronic® gearbox: the gearbox continuously adapts the
gear ratios to gradients. If the brake pedal is pressed on a downhill gradient
the gearbox automatically shifts to a lower gear ratio. This increases the en-
gine braking effect.
Vehicles with tiptronic gearbox: in mountainous areas, the gearbox adapts
the gears for uphill and downhill gradients. This helps to avoid constant
gear changes on uphill gradients.
Manual gear selection (tiptronic mode)
With the manual shift programme (tiptronic) the driver can
manually select pre-programmed gears.

Switching over to the manual programme
– Move the selector lever from the position D to the right-hand
side. As soon as the selector lever has entered the tiptronic rail,
the gear engaged is displayed on the screen.
Shifting up a gear
– Briefly push the selector lever forwards (in the tiptronic gate)

With the tiptronic system, the driver can manually choose between eight (in
vehicles with multitronic) or seven (in vehicles with tiptronic) different gear
programmes. The manual programme can be selected either with the vehi-
cle stationary or on the move.
When accelerating, the gearbox automatically shifts up into the next gear
shortly before the maximum engine speed is reached.

Intelligent technology
WARNING
The ESC is not able to overcome the physical limits of adhesion. Even
with ESC, you should always adjust your speed to suit the road and traffic
conditions. Please bear this in mind, especially on wet or slippery road
surfaces. Do not let the extra safety features tempt you into taking any
risks when driving. Failure to do so could result in an accident.
Anti-lock brake system (ABS)
ABS prevents the wheels from locking up under braking.
The anti-lock brake system (ABS) is an important part of the vehicle's active
safety system. However, the ABS will not necessarily guarantee shorter
stopping distances in all conditions. For instance, on loose gravel or fresh
snow on top of an icy surface (conditions which anyway require extreme
care and reduced speed), the stopping distance with ABS may even be
slightly longer.
How the ABS works
The system runs an automatic self-check when the vehicle reaches a road
speed of about 6 km/h. This may be accompanied by a noise from the ABS
pump.
When one of the wheels is turning very slowly in relation to the road speed
and is close to locking up, the system will reduce the brake pressure on that
wheel. The driver is made aware of this adjustment process by a vibration of
the brake pedal and an audible noise. This is a deliberate warning to the
driver that one or more of the wheels is tending to lock up and the ABS con-
trol function has intervened. In this situation it is important to keep the
brake pedal fully depressed so the ABS can regulate the brake application,
but do not “pump” the brake pedal.
WARNING
The grip provided by ABS is still subject to the physical limits of adhe-
sion. Always bear this in mind, especially on wet or slippery roads. If you
notice that the ABS is working (to counteract locked wheels under brak-
ing), 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. Failure to do so could result in an accident.
Note
If a malfunction should occur in the ABS, this is indicated by a warning lamp
⇒ page 68.
Brake assist system
The brake assist system helps the driver to achieve optimum
braking effect.
The brake assist system helps to increase braking power and thus to ach-
ieve a shorter stopping distance. If the driver presses the brake pedal very
quickly, the brake assist system automatically boosts the braking force to
the maximum level, up to the point where the anti-lock brake function (ABS)
intervenes to stop the wheels from locking. You should then keep the brake
pedal pressed until the vehicle has braked to the required speed. The brake
assist system switches itself off as soon as you release the brake pedal.
The brake assist system will not be operative if there is a malfunction in the
ABS or the ESC.

Intelligent technology
The traction control system (ASR) helps the car to start moving, accelerate
and climb a gradient in slippery conditions where this may otherwise be dif-
ficult or even impossible.
How it works
The ASR works automatically, i.e. without the driver's involvement. With the
aid of the ABS sensors , the ASR monitors the speed of the driven wheels
⇒ page 189. If the wheels start to spin, the engine speed is reduced auto-
matically to match the amount of grip available. The system is active across
the entire speed range.
The ASR works in conjunction with the ABS. If a failure occurs in the ABS,
the ASR will also stop working.
In general, the ASR should be left switched on at all times. It should only be
switched off manually in particular circumstances where a certain amount of
wheel slip may be desirable. Examples:
● when driving with snow chains
● when driving in deep snow or on loose surfaces
● when rocking the vehicle backwards and forwards to free it.
The ASR should be switched on again afterwards as soon as possible.
Note
To ensure that the ASR works properly, all four wheels must be fitted with
identical tyres. The difference in size of the wheels may lead to an unde-
sired reduction in engine power. Also see ⇒ page 247.

Intelligent technology
Brake servo
The brake servo assists the driver when braking
The brake servo increases the pressure you apply to the brake pedal. The
brake servo works only when the engine is running.
WARNING
Ensure the vehicle does not move while in neutral, when the engine is
stopped. Failure to do so could result in an accident.
Note
If the brake servo is not working, e.g. because the vehicle has to be towed
or because it is broken, you will have to press the brake pedal considerably
harder to make up for the lack of servo assistance.
Power steering
Power steering makes it easier to turn the steering wheel
when the engine is running. Power steering assists the driver by reducing the force needed to turn the
steering wheel.
Power steering does not work if the engine is off. In this case the steering
wheel requires much more force to turn.
If the steering is held at its turning limit when the vehicle is stationary, this
will place an excessive load on the power steering system. Turning the
steering wheel to its limit places a load on the system, which causes noise.
It will also reduce the idling speed of the engine.
CAUTION
When the engine is running, do not turn the steering wheel to its limit for
more than 15 seconds. Otherwise, there is a risk of damaging the power
steering.
Note
● If the power steering should fail at any time or the engine is switched off
(for instance when being towed), the vehicle can still be steered. However,
more effort will be required to turn the steering wheel.
● If the system is leaking or malfunctioning, please take the vehicle to a
specialised workshop as soon as possible.
● The power steering system requires a special hydraulic fluid. The fluid
reservoir is located at the front of the engine compartment on the left
⇒ page 296. The correct fluid level in the reservoir is important for the pow-
er steering to function properly. The hydraulic fluid level is checked at the
Inspection Service.
Servotronic*
The servotronic system electronically adjusts the power as-
sisted steering.
In vehicles equipped with servotronic power steering the degree of power
assistance ⇒ page 193 is adjusted
electronically according to road speed.
If a fault should occur in the servotronic system, the power steering will still
operate. The degree of power assistance will, however, no longer adapt to
different speeds. If the electronic regulating system is not working properly,
this is most noticeable when turning the steering wheel at low speeds (for
instance when parking), as more effort will be required than usual. The fault
should be corrected by a specialised workshop as soon as possible.
