Radio remote control
synchronisation The radio remote control
synchronises itself automatically
during every starting procedure.
Fault If the central locking cannot be
operated or the engine cannot be
started, the cause may be one of the
following:
■ fault in remote control 3 20
■ electronic key out of reception range
To rectify the cause of the fault,
change the position of the electronic
key.Central locking system
Unlocks and locks doors, load
compartment and fuel filler flap.
A pull on an interior door handle
unlocks the entire vehicle and opens
the door.
Note
In the event of an accident of a
certain severity, the vehicle unlocks
automatically.
Note
A short time after unlocking with the
remote control the doors are locked
automatically if no door has been
opened.Unlocking

System settings
Press the Main button of the
Infotainment system.
Press the Settings button on the
Infotainment system. For
Infotainment system CD 30, no menu may be selected.
Setting date and time
Select menu item Time, Date from the
Settings menu.
Select the required menu items and
make settings.
Changing the time setting will also
change the time setting of the
navigation system.
Automatic time synchronisation
The RDS signal of most VHF
transmitters automatically sets the time.
Some transmitters do not send a
correct time signal. In such cases, we recommend to switch off automatic
time synchronisation.
The function is activated by ticking the
field in front of Synchron. clock
automatical. in the Time, Date menu.
Language selection
The display language for some
functions can be selected.
Select menu item Language from the
Settings menu.
Select the desired language.
Driving and operating149
Winter programme activation not
possible.
Deactivation
Briefly press the SPORT button.
Sport mode is deactivated the next
time the ignition is switched on or if
the Winter programme is activated.
Continuous damping
control Continuous damping control (CDC)
changes suspension with damping
adaptation of each shock absorber to the current driving situation and road
conditions.
When Sport mode is engaged, the
damping control is adapted to a
sportier driving style.
Control indicator IDS+ 3 100.Automatic level control
The rear level of the vehicle is
automatically adjusted to the load
conditions while driving. Suspension
and ground clearance are increased,
which improves driving conditions.
The automatic level control is
activated after the vehicle has been
driven for some distance, depending
on the vehicle loading and the road conditions.
Do not use full payload in the event of
a fault. Have the cause of the fault
remedied by a workshop.Cruise control
The cruise control can store and
maintain speeds of approx.
30 to 200 km/h. Deviations from the
stored speeds may occur when
driving uphill or downhill.
For safety reasons the cruise control
cannot be activated until the foot
brake has been operated once.
Do not use the cruise control if it is not
advisable to maintain a constant
speed.

Accessories and vehicle
modifications
We recommend using genuine parts and accessories and factory
approved parts specific for your
vehicle type. We cannot assess or guarantee reliability of other products
- even if they have a regulatory or
otherwise granted approval.
Do not make any modifications to the electrical system, e.g. changes of
electronic control units (chip tuning).Caution
When transporting the vehicle on
a train or on a recovery vehicle, the
mud flaps might be damaged.
Vehicle storage
Storage for a long period of time
The following must be done if the
vehicle should be stored for several months:
■ Wash and wax the vehicle.
■ Have the wax in the engine compartment and underbody
checked.
■ Clean and preserve rubber seals.
■ Fill up fuel tank completely.
■ Change engine oil.
■ Drain washer fluid reservoir.
■ Check coolant antifreeze.
■ Adjust tyre pressure to the value specified for full load.
■ Park vehicle in dry, well ventilated place. Engage first or reverse gear
or set selector lever to P. Prevent
the vehicle from rolling.
■ Do not apply parking brake.
Vehicle care191
The tyre pressure tables show all
possible tyre combinations 3 225.
For the tyres approved for your
vehicle, refer to the EEC Certificate of Conformity provided with your vehicle
or other national registration
documents.
The driver is responsible for correct
adjustment of tyre pressure.9 Warning
If the pressure is too low, this can
result in considerable tyre warm-
up and internal damage, leading to tread separation and even to tyre
blow-out at high speeds.
Tyre pressure monitoring
system
The tyre pressure monitoring system
continually checks the pressure of all
four wheels when vehicle speed
exceeds a certain limit.
All wheels must be equipped with
pressure sensors and the tyres must
have the prescribed pressure.
Otherwise, the tyre pressure will be monitored by the deflation detection
system 3 191.
Note
In countries where the tyre pressure
monitoring system is legally
required, the use of wheels without
pressure sensors will invalidate the
vehicle type approval.
The current tyre pressures can be
shown in the Info-Display 3 116.
Vehicle messages, tyre pressure
3 111.
Control indicator w 3 99.
If a complete set of wheels without
sensors is mounted (e.g. four winter
tyres), no error message will be
displayed. The tyre pressure
monitoring system is not operational.
Retrofitting of sensors is possible.
The use of commercially available
liquid tyre repair kits can impair the
function of the system. Factory-
approved systems can be used.
External high-power radio equipment
could disrupt the tyre pressure
monitoring system.System initialisation
After a wheel change, the system
must be initialised: inflate the tyres to
the prescribed pressure, switch on
the ignition, then press and hold the
DDS button for approx. 4 seconds;
control indicator w flashes three
times.
Tyre deflation detection
system
The tyre deflation detection system
continually checks the rotation speed
of all four tyres.
192Vehicle care
If a tyre loses pressure the control
indicator w illuminates red. Stop
immediately and check tyre pressure.
Control indicator w 3 99.
System initialisation
After tyre pressure correction or
wheel change, the system must be
initialised: Switch on the ignition,
press and hold the DDS button for
approx. 4 seconds, control indicator
w flashes three times.
Tread depth
Check tread depth at regular
intervals.
Tyres should be replaced for safety
reasons at a tread depth of 2-3 mm
(4 mm for winter tyres).
The legally permissible minimum
tread depth (1.6 mm) has been
reached when the tread has worn
down as far as one of the tread wear
indicators (TWI). Their position is
indicated by markings on the
sidewall.
If there is more wear at the front than
the rear, swap round front wheels and rear wheels periodically.
Tyres age, even if they are not used.
We recommend tyre replacement
every 6 years.
Changing tyre and wheel
size If tyres of a different size than those
fitted at the factory are used, it may be necessary to reprogram the
speedometer and make other vehicle
modifications.
After converting to a different tyre
size, have the label with tyre
pressures replaced.9 Warning
Use of unsuitable tyres or wheels
may lead to accidents and will
invalidate the vehicle type
approval.
