Starting-off and Driving 102•
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 216.
•
Contact the nearest specialist garage to obtain professional assistance.
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 posi-
tion into ⇒page 100, fig. 124.
WARNING
•
Never switch off the engine before the vehicle is stationary - risk of acci-
dent!
•
The brake booster only operates when the engine is running. Greater
physical effort for braking 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 temperature 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 185, “Working in the engine compartment”.
Shifting (manual gearbox)Shift into reverse only when the vehicle 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 light will come on once reverse gear is engaged, provided the ignition
is on.
WARNING
Never engage the reverse gear when driving - risk of accident!

Starting-off and Driving 104Parking 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. 127). The interval between the warning signals becomes shorter as the
clearance is reduced.
A continuous tone sounds from a distance of approx. 30 cm (area ) - 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 acknowledgement 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
•
When operating with a trailer, the parking aid is without function.
•
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. It is possible that the audible warning does not function correctly
(an obstacle behind the vehicle may not be detected - take extra care). 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)*IntroductionThe cruise control system (CCS) maintains a constant speed, more than 30 km/h,
once it has been set, without you having to depress the accelerator 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 switch and
rocker button in the left lever of the multi-functional switch.
– Press the switch ⇒fig. 128 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.
You can increase the speed by depressing the accelerator. Releasing the acceler-
ator 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 tempo-
rarily by actuating the brake or clutch pedal ⇒page 106.
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.Fa s t er
–You can increase the stored speed without depressing the acceler-
ator, by pressing the rocker button ⇒fig. 128 into the RES+ posi-

Automatic gearbox6-speed automatic gearbox*IntroductionYour car is equipped with an electronically controlled 6-speed automatic gearbox.
Shifting up and also down through the gears is performed automatically.
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 with an automatic gearbox
Shifting up and down through the gears is performed automatically.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 110.
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 108,
and then release the Shiftlock button.
– Wait a moment until the gearbox has shifted (a slight engagement
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 stop-
ping 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
⇒page 100.
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 neces-
sary 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.
WARNING
•
Do not depress the accelerator when changing the position of the
selector lever if the car is stationary and the engine is running - risk of acci-
dent!
•
Never move the selector lever into position R or P when driving - risk of
an accident!

When the engine is running and the vehicle is stationary, it is necessary
to hold the car with the brake pedal in all the positions of the selector lever
(except P and N) since the power transmission is never completely inter-
rupted, also not when the engine is idling - the vehicle creeps.
Selector lever positionsThe selector lever position you have engaged is shown in the information display
of the instrument cluster with the corresponding gear symbol highlighted ⇒fig. 130. In the positions D and S the gear you have already engaged will be addi-
tionally displayed on the display.

Technical Data In certain circumstances (e.g. when driving in mountainous regions or when towing
a trailer) it may be beneficial to select the manual shift programme ⇒page 110 for
a short time in order to adapt the gearbox ratios manually to the driving situations.
S - Position for sporty style of driving
Shifting up later into a higher gear makes it possible to fully exploit the power
potential of the engine. The gearbox also then shifts down at higher engine speeds
as in the position D.
The gearbox does not shift into the 6th gear in the position S, because the
maximum speed is achieved with the 5th gear.
The Shiftlock on the selector lever grip must be pressed when moving the selector
lever out of the position D into the position S.
WARNING
•
Never move the selector lever into position R or P when driving - risk of
an accident!
•
When the engine is running and the vehicle is stationary, it is necessary
to hold the car with the brake pedal in all the positions of the selector lever
(except P and N) since the power transmission is never completely inter-
rupted, also not when the engine is idling - the vehicle creeps.
•
You must on no account unintentionally operate the throttle (e.g. by
hand from the engine compartment) if a drive position is engaged when the
car is stationary. The vehicle would otherwise immediately start off - also
when the handbrake is firmly applied - risk of an accident!
•
You must move the selector lever into position P and firmly apply the
handbrake first before you or any other person opens the bonnet and starts
working on the engine when it is running - risk of accident! It is also essential
to observe all warnings ⇒page 185, “Working in the engine
compartment”.
Selector lever lockAutomatic selector lever lock
With the ignition on, the selector lever is locked when it is in the positions P and N.
You must first of all depress the brake pedal in order to move the selector lever out
of this position. The warning light
⇒page 32 lights up in the instrument cluster
as a reminder for the driver when the selector lever is in position P and N.
A time delay element ensures that the selector lever is not blocked when rapidly
switching over the position N (e.g. from R to D). This does, for example, allow one
to seesaw out a stuck vehicle. The selector lever lock will click into place if the lever
is in the N position for more than 2 seconds without the brake pedal being pressed.
The selector lever lock is only active if the vehicle is stationary or moving at speed
of less than 5 km/hour. The lock is switched off automatically into position N when
the car is travelling at a higher speed.
Shiftlock button
The Shiftlock button in the handle of selector lever prevents certain selector lever
positions being engaged inadvertently. The selector lever lock is cancelled when
you press the Shiftlock button.

You can only withdraw the ignition key after switching off the ignition if the selector
lever is in position P. If the ignition key is withdrawn, the selector lever is blocked in
position P.
Kickdown function
The kickdown function provides you with maximum acceleration
power.Fully depressing the accelerator pedal allows the kickdown function to be activated
in the desired driving program. This function has precedence over the driving
programme and serves for maximum acceleration of the vehicle when exploiting
the maximum power potential of the engine without taking into account the 5)This function is only valid for some countries.

Automatic gearbox 110current selector lever position (D, S or Tiptronic). The gearbox shifts down to one
or several gears in line with the driving state and the vehicle accelerates. The
gearbox does not shift up into the highest gear until the engine has reached its
maximum revolutions for this gear range.
WARNING
Please note that using the kickdown function can result in the driven wheels
spinning on a smooth or slippery road surface - risk of skidding!Dynamic shift programmeThe automatic gearbox of your vehicle is controlled electronically. Shifting up and
down through the gears is performed automatically on the basis of pre-defined
driving programmes.
Adopting a moderate style of driving will cause the gearbox to select the most
economical driving programme. Shifting up into a higher gear as soon as possible
and shifting down as late as possible will have a favourable effect on your fuel
consumption.
Adopting a sporty style of driving with rapid movements of the accelerator pedal
combined with sharp acceleration and frequent changes in speed, exploiting the
top speed of the car or depressing the accelerator pedal (kickdown function), will
cause the gearbox to switch over to this style of driving and shift down earlier with
frequent changes in gears in comparison to the moderate style of driving.
Selecting the most appropriate driving programme for the particular style of driving
is a continuous process. Irrespective of this it is, however, possible to switch or shift
down into a dynamic shift programme by depressing the accelerator rapidly. The
gearbox shifts down into a lower gear matching the speed of the car and this allows
you to accelerate rapidly (e.g. when overtaking) without having to depress the
accelerator pedal fully into the kickdown range. The original programme will be
reactivated to match your particular style of driving once the gearbox has shifted up
again.
When driving in hilly regions, the gears are selected to match uphill and downhill
sections. This avoids the gearbox frequently shifting up and down when negotiating an uphill stretch. When driving downhill, it is possible to shift down into the
Tiptronic position, in order to exploit the engine brake torque.
Tiptronic
The Tiptronic allows the driver to also shift gears manually.Switching over to manual shifting
– Push the selector lever to the right out of position D. After switching
over, 6 5 4 3 2 1 appears in the display with the currently engaged gear
being highlighted.

Shifting down gears
– One-touch back of the selector lever (in the Tiptronic position) .It is possible to switch over to manual both when the car is stationary and also when
driving.
When you accelerate, the gearbox shifts up automatically in gears 1, 2, 3, 4 and 5
into the next higher gear just before the maximum permissible engine speed is
reached.
If you select a lower gear, the automatic gearbox does not shift down until there is
no risk of the engine overrevving.
If you operate the kickdown function, the gearbox shifts into a lower gear in line
with the vehicle speed and engine speed.Emergency programme
An emergency programme exists in the event of a fault in the system.The gearbox operates in a corresponding emergency programme if there are func-
tional faults in the gearbox electronics. This is indicated by all of the segments in the
display lighting up or going out.
It is possible to continue to move the selector lever into all the positions. In the
positions D and S the gearbox remains engaged in the 3rd gear. It is also possible to
continue to engage reverse gear in the position R.
The manual shift programme (Tiptronic) is switched off in the emergency mode.
If the gearbox has switched over to emergency mode, drive to the nearest
specialist garage in order to have the fault rectified.
