Coolant temperature display
Coolant temperature display For physical reasons, the engine
temperature gauge shows the coolant
temperature only if the coolant level is
adequate.
During operation the system is pressurised.
The temperature may therefore rise briefly
to over 100 C.

Fuel gauge
Fuel tank level display.
If the fuel level is too low, a warning lamp
lights up

soon as possible.
Never run the tank dry!
Because of the fuel remaining in the tank,
the amount of fuel required to fill the
tank may be less than the specified tank
capacity.

beam/parking lamps are on.
Operated with the r button.
The fog tail lamps on the vehicle are
deactivated when towing a caravan/
trailer.
Reversing lamps The reversing lamps come on when the
ignition is on and reverse gear is engaged.

Manoeuvring the vehicle
For accurate manoeuvring when parking,
at garage entrances etc., the creeping
movement can be utilised by releasing the
foot brake with a gear selected.
Never actuate accelerator and brake
pedals simultaneously.
To prevent damage, the manual
transmission automated deactivates the
"creep function" when the temperature of
the automatic clutch is extremely high. Vehicle storage
Apply the handbrake and remove the key
from the ignition. The most recently
engaged gear (indicator in transmission
display) remains engaged. With
N, no gear
is engaged.
When the ignition is switched off the
manual transmission automated no longer
responds to movement of the selector
lever.
If the ignition key is not removed, the
battery may be discharg ed if the vehicle is
then left to stand for a lengthy period of
time.
If the hand brake has not been applied, the
control indicator R flashes for a few
seconds after the ignition is switched off.
Picture no: 17890s.tif
Fault
To prevent damage to the automated
manual transmission, the clutch is closed
automatically at high clutch temperatures.
Warning light A lights up if there is a fault.
It is possible to continue driving but manual
mode can no longer be used for changing
gear.
If "F" also appears in the transmission
display, it is not possible to continue
driving.
Have cause of fault remedied by a
workshop. The system’s integrated self
diagnostics allow faults to be quickly
remedied.

Driving and operation
Control indicator
v
The warning light lights up for a few
seconds when ignition is switched on. Once
it goes out, the system is ready for
operation.
Flashing during driving:
This shows the system has come into
action. The engine output may be reduced
(the sound of the engine changes) and the
vehicle may be braked automatically to a
small degree.
Picture no: 17892s.tif
Illuminates while driving:
Fault in the system. Driving can be
continued. Poor road surface conditions
may however still cause vehicle stability to
be impaired.
Have the cause of the fault eliminated.
Self-diagnosis integrated into the system
allows rapid fault identification. Illuminates after interruption of power
supply e.g. after disconnecting battery.
After a power supply interruption the
steering angle sensor must be calibrated to
make the system operational:
z
Automatic calibration driving in straight
line at constant slow (20 to 40 km/h)
speed on level, dry road.
z Manual calibration by turning steering
wheel from limit position to limit position.
If the indicator lamp does not go off after
successful calibration , observe notes in
middle column.

148 Driving and operationCruise control 3
Cruise control can store and maintain
speeds of approx. 30 to 200 km/h.
Deviation from the stored speed is possible
on uphill or downhill inclines.
For safety reasons the cruise control
cannot be activated until the foot brake
has been operated once.
The cruise control is operated with the
buttons I, R and O on the turn signal lever.
Do not use the cruise control if it is not
advisable to maintain a constant speed
(e.g. in situations presenting a danger to
yourself and other road users, in heavy
traffic or on winding, slippery or greasy
roads). For manual transmission automated
3,
engage cruise control in automatic mode
only.

Control indicator
m 3
The warning lamp lights up for a few
seconds 3 when the ignition is switched on.
The system is now ready for operation.
When driving, th e warning lamp m lights
up as soon as the sy stem is switched on.
9 Warning
When the cruise control is active,
reaction times may be increased due to
the different position of the feet.

Hand brake Always apply hand brake firmly without
pressing the release button, and apply as
firmly as possible on steep slopes.
To release the hand brake pull lever up
slightly, press release button, and lower
lever all the way down.
To reduce the operating forces of the hand
brake, depress the foot brake at the same
time.
Brake assist If the brake pedal is operated quickly with
a powerful push, the vehicle is
automatically braked at full braking power
in order to achieve the shortest possible
braking distance when full-on braking
occurs (brake assist).
Maintain steady pressure on the brake
pedal for as long as full-on braking is to
continue. When the brake pedal is
released, the maximum brake force
amplification is taken away. Hill Start Assist
3 (HSA)
The system helps pull away on inclines.
After releasing the footbrake, if the hand
brake is not applied the brakes are only
released after 2 seconds. As soon as the
acceleration is sufficient to prevent rolling
back, the brake is released.
Wheels, tyresSuitable tyres and restrictions 3 228.
Tyres fitted in the factory are adapted to
the chassis and provide optimum driving
comfort and safety.
Changing tyre/wheel type
If tyres of a different size than those fitted
at the factory are used, it may be
necessary to reprogram the electronic
speedometer and make other vehicle
modifications.
After converting to a different tyre size,
have the adhesive label with tyre pressures
replaced.
9 Warning
Use of unsuitable tyres or wheels may
lead to accidents and render the vehicle
unroadworthy.

174 Self-help, vehicle careChanging wheels There may be a tyre repair kit instead of a
spare wheel 3178.
Make the following preparations and
observe the following information:
z Park the vehicle on a level, firm and non-
skid surface. The front wheels must be in
the straight-ahead position.
z Switch on the hazard warning flashers,
apply the hand brake, engage first gear
or reverse.
z Erect warning triangle as specified.
Warning triangle 3171.
z Remove the spare wheel 3 172.
z Never change more than one wheel at
once.
z Use the jack 3 only to change wheels. z
If the ground on which the vehicle is
standing is soft, a solid board (max. 1 cm
thick) should be placed under the jack 3.
z Block the wheel diagonally opposite the
wheel to be changed by placing wedge
blocks or equivalent in front and behind
the wheel. z
No people or animals may be in the
vehicle when it is jacked up.
z Never crawl under a jacked-up vehicle.
z Do not start the vehicle when it is raised
on the jack.
z Before screwing in the wheel bolts, clean
them and lightly coat the taper of each
wheel bolt with comm ercially available
grease.
