Starting-off and Driving
112
For the sake of the environment
Never warm up the engine when the vehicle is standing. Drive off right
away. When driving the engine reaches its operating temperature more
rapidly and the pollutant emissions are lower.
Petrol engines
These engines are fitted with a starter system which selects the correct
fuel/air mixture for every external air temperature.
•Do not operate accelerator before and when starting engine.
•Interrupt the attempt at starting after 10 seconds if the engine does not
start right awayand wait for about 30 seconds before repeating the
attempt.
•It is possible that the fuse on the electrical fuel pump is defect if the
engine still does not start. Check the fuse and replace it if necessary
⇒ page 249.
•If the engine does not start, contact the nearest specialist garage to
obtain professional assistance.
It may be necessary, if the engine is very hot, to slightly depress the
accelerator after the engine has started.
Diesel engines
Glow plug system
Diesel engines are equipped with a glow plug system, the preglow period
being controlled automatically in line with the coolant temperature and
outside temperature. The preglow indicator light
comes on after the ignition has been
switched on.
You should not switch on any major electrical components during
the heating period otherwise the vehicle battery will be drained
unnecessarily.
•You should start the engine immediately after the glow plug warning
light has gone out.
•The glow plug warning light will come on for about one second if the
engine is at a normal operating temperature or if the outside temperature
is above +5°C. This means that you can start the engine right away.
•Interrupt the attempt at starting after 10 seconds if the engine does not
start right awayand wait for about 30 seconds before repeating the
attempt.
•It is possible that the fuse on the diesel preglow system is defect if the
engine still does not start. Check the fuse and replace it if necessary
⇒ page 249.
•Contact the nearest specialist garage to obtain professional assist-
ance.
Starting the engine after fuel tank has run dry
It may take longer than normal to start the engine after refuelling if the fuel
tank has run completely dry - up to one minute. This is because the fuel
system must first of all be filled while the attempting to start the engine.
Switching off the engine
– The engine can be switched off by turning the ignition key from position ⇒page 110, fig. 100 into position .

WARNING
•Never switch off the engine before the vehicle is stationary - risk
of accident!
•The brake booster only operates when the engine is running.
Greater physical effort for brakin g is required when engine is
switched off. Because if you do not stop as normal, this can cause
an accident and severe injuries.
Caution
you should not switch the engine off right away at the end of your journey
after the engine has been operated for a lengthy period at high loads but
should be allowed it to run at idling speed for about 2 minutes. This
prevents any accumulation of heat when the engine is switched off.
Note
•The radiator fan may continue running for a further 10 minutes or so
after the engine and the ignition have been switched off. The coolant fan
may, however, also switch on again after some time if the coolant temper-
ature rises because of an accumulation of heat in the engine or if the
engine is warm and the engine compartment is additionally heated by
strong sunlight.
•This is why particular care is required when carrying out any work in
the engine compartment ⇒page 210, “Working in the engine
compartment”.
Shifting (manual gearbox)
Shift into reverse only when the car is stationary. Depress the clutch pedal
and hold it fully depressed. Wait a moment before engaging reverse gear
in order to avoid any shift noises.
The reversing lights will come on once reverse gear is engaged, provided
the ignition is on.
WARNING
Never engage the reverse gear when driving - risk of accident!
Note
•One should not lay the hand on the shift lever while driving the vehicle.
The pressure of the hand will be transferred to the gearshift forks in the
gearbox. This can, over a period of time, lead to early wear of the gearshift
forks.

•Depress the clutch pedal fully when changing gears, in order to avoid
unnecessary wear and damage.
Handbrake
Applying the handbrake
– Pull the handbrake lever up fully.
Releasing the handbrake
– Pull the handbrake lever up slightly and at the same time
press in the locking button ⇒fig. 102 .
– Hold the button pressed and push the handbrake lever down fully ⇒ .
The handbrake warning light lights up when the handbrake is applied,
provided the ignition is on.
A warning signal sounds and the following text appears in the display* if
you have inadvertently driven off with the handbrake applied:
HANDBRAKE ON
The handbrake warning is activated if you drive at a speed of more than 6
km/h for more than 3 seconds.
WARNING
•Please note that the handbrake must be fully released. A hand-
brake which is only partially released can result in the rear brakes
overheating which will have a negative effect on the operation of
the brake system - risk of accident! In addition this can result in
premature wear of the rear brake pads.
•Never leave children unattended in the vehicle. The children
might, for example, release the handbrake or take the vehicle out of
gear. The vehicle might then move off - risk of accident!
Caution
After the car has come to a stop, always first of all apply the handbrake
firmly before then additionally engaging a gear (manual gearbox) or
moving the selector lever into position P (automatic gearbox).

Parking aid*
The parking aid provides a warning of obstacles behind
the vehicle.
The audible parking aid determines the distance between the rear bumper
and an obstacle located behind the vehicle with the aid of ultrasound
sensors. The sensors are integrated in the rear bumper.
Range of sensors
The clearance warning begins at a distance of about 160 cm from the
obstacle (area ⇒fig. 103 ). The interval between the warning signals
becomes shorter as the clearance is reduced.
A continuous tone sounds from a clearance of just 30 cm (Bereich ) -
danger area. You should not reverse any further after this signal
sounds! Activating
The parking aid is activated automatically when
reverse gear is engaged
and the ignition is turned on. This is confirmed by a brief acknowledge-
ment signal.
Deactivating
The parking aid is deactivated by removing the reverse gear.
WARNING
•The parking aid is not a substitute for the driver paying proper
attention and it is always the driver's responsibility to take care
when parking the vehicle or carrying out similar manoeuvres.
•You should therefore satisfy yourself, before reversing, that
there is no small obstacle, such as a rock, thin post, trailer drawbar
etc., behind your vehicle. Such an obstacle might not be within the
range detected by the sensors.
Note
•The parking aid does not operate if you are towing a trailer (applies to
models which feature a factory-fitted towing device*).
•A system fault is indicated if a warning signal sounds for about 5
seconds after switching the ignition on and engaging reverse gear and
there is no obstacle close to your vehicle. Have the fault rectified by a
specialist workshop.
•The sensors must be kept clean and free of ice to enable the parking
aid to operate properly.
•If the parking aid is activated and the selector lever of the automatic
gearbox is in the position , warning signal indicates interruption (vehicle
can no longer move).

Cruise control system (CCS)*
Introduction
The cruise control system (CCS) maintains a constant speed, more than
30 km/h, once it has been set, without you having to depress the acceler-
ator pedal. This is only possible within the range which is permitted by the
power output and braking power of the engine. The cruise control system
makes it possible - particularly on long journeys - for you to rest your
“accelerator foot”.
WARNING
•The cruise control system must not, for safety reasons, be used
in dense traffic or on unfavourable road surfaces (such as icy
roads, slippery roads or loose chippings) - risk of accident!
•In order to prevent unintentional use of the cruise control
system, always switch off the system after use.
Note
•Models fitted with a manual gearbox: Always depress the clutch pedal
if you switch on the cruise control system when the gearbox is in Neutral.
Otherwise the engine can rev up unintentionally.
•The cruise control system is not able to maintain a constant speed
when driving on steep downhill sections. The weight of the vehicle
increases the speed at which it travels. One should shift down in good time
to a lower gear or slow the vehicle down by applying the foot brake.
•It is not possible on vehicles fitted with an automatic gearbox to switch
on the cruise control system if the selector lever is in the position P, N or
R .
Storing a speed
The cruise control system is operated by means of the slide
switch and rocker button in the left lever of the multi-func-
tional switch.
– Press the switch ⇒fig. 104 into the position ON.
– After the desired speed has been reached, press the rocker button into the SET position - the current speed is stored.
After you have released the rocker button out of the position SET, the
speed you have just stored is maintained at a constant speed without
having to depress the accelerator.
Yo u c a n increase the speed by depressing the accelerator. Releasing the
accelerator will cause the speed to drop again to the set speed.
This does not apply, however, if you drive at a speed which is more than
10 km/h higher than the set speed for a period of longer than 5 minutes.

The stored speed will be cancelled in the memory. You then have to re-
store the desired speed.
One can
reduce the speed in the usual manner. The system is switched
off temporarily by actuating the brake or clutch pedal ⇒page 117.
WARNING
First ensure that it is not too high for the traffic conditions which
exist at that moment before resuming the stored speed.
Changing a stored speed
You can also change the speed of the vehicle without
depressing the accelerator.
Faster
– You can increase the stored speed without depressing the
accelerator, by pressing the rocker button ⇒page 116,
fig. 104 into the RES position.
– The speed of the car will increase continuously if you hold the rocker button pressed in the RES position. Once the car has
reached the desired speed, release the rocker button. The set
speed is then stored in the memory.
Slower
– You can reduce the stored speed by pressing the rocker
button in the SET position. – Holding down the rocker button pressed in the
SET position
will cause the speed of the vehicle to reduce continuously.
Once the car has reached the desired speed, release the
rocker button. The set speed is then stored in the memory.
– If you release the rocker button when the car is travelling at a speed of less than 30 km/h, the speed is not stored, the
memory is erased. It is then necessary to again store the
speed with the rocker button in the position SET after an
increase in speed of the vehicle to more than 30 km/hour.
Switching off the cruise co ntrol system temporarily
– You can switch off temporarily the cruise control system, if
you depress the brake or clutch pedal.
– You can switch off temporarily t he cruise control system, if you
press the switch in the middle position.
The set speed remains stored in the memory.
Press the rocker button in the position RES for the resumption of the
stored speed after releasing the clutch or brake pedal.
WARNING
First ensure that it is not too high for the traffic conditions which
exist at that moment before resuming the stored speed.

Automatic gearbox
6-speed automatic gearbox*
Introduction
Your car is equipped with an electronically controlled 6-speed automatic
gearbox. Shifting up and also down through the gears is performed auto-
matically.
At the same time this is a conventional automatic gearbox. The maximum
speed is reached in the 5th gear. The 6th gear serves as an economic
driving programme, which is intended to reduce the fuel consumption.
Information for driving wi th an automatic gearbox
Shifting up and down through the gears is performed auto-
matically.
You can also, however, switch the gearbox over into the
Tiptronic mode . This mode makes it possible for you to also shift
gears manually ⇒page 123.
Starting-off and Driving
– Depress the brake pedal and hold it depressed.
– Press the Shiftlock button (button in handle of the selector lever), move the selector lever into the desired position, e.g. D
⇒ page 120, and then release the Shiftlock button. – Wait a moment until the gearbox has shifted (a slight engage-
ment nudge can be felt).
– Release the brake pedal and depress the accelerator ⇒.
Stopping for a short time
– The selector lever position N does not have to be selected
when stopping just for a short time, such as at a cross roads.
It is sufficient to hold the vehicle stationary using the foot
brake. The engine can, however, be allowed just to idle.
Parking
– Depress the brake pedal and hold it depressed.
– Apply the handbrake firmly.
– Press and Shiftlock button in the selector lever, move the selector lever to P and then release the Shiftlock button.The engine can only be started when the selector lever is in position P or
N ⇒ p a g e 111 .
It is sufficient to engage selector lever position P when parking on a flat
surface. When parking on a slope you should first apply the handbrake
firmly and then move the selector lever into position P. This is to ensure
that there is no excessive pressure acting on the lock mechanism and that
it is easier to subsequently move the selector lever out of position P.
If the selector lever position N is selected by accident while driving it is first
necessary to release pressure on the accelerator pedal and wait for idling
speed of the engine to be reached before engaging a drive position in the
selector lever.
