any time by pressing and holding the
button on the end of the wiper lever.
Average consumption
The value is displayed after driving a
distance of 400 metres.
Average consumption is displayed, taking into consideration the distance
travelled and the fuel used since the
last reset.
The measurement can be restarted at
any time.Instantaneous consumption
The value is displayed after reaching a speed of 30 km/h.
Range The value is displayed after driving adistance of 400 metres.
The range is calculated from the
current contents of the fuel tank and
the average consumption since the
last reset.
The range will not display if control
indicator Y is illuminated in the
instrument cluster 3 96.
The measurement can be restarted at
any time.
Distance travelled
Displays the distance driven since the
last reset.
The measurement can be restarted at
any time.
Average speed
The value is displayed after driving a
distance of 400 metres.The average speed since the last reset is displayed.
The measurement can be restarted at
any time.
Interruptions in the journey with the
ignition off are not included in the
calculations.

To reset the trip computer, select one of its functions then press and hold
button on end of wiper lever.
The following trip computer
information will be reset:

Adjustable air vents may be located inthe roof frame above the seats. Turn
adjuster to increase/decrease airflow
to the appropriate seat.
Fixed air vents Additional air vents are located
beneath the windscreen and door
windows and in the foot wells.
Glovebox cooler
The air conditioning system can also
keep the contents of the glovebox
cool.
Maintenance
Air intake
The air intake in front of the
windscreen in the engine
compartment must be kept clear to
allow air intake. Remove any leaves,
dirt or snow.
Pollen filter The pollen filter cleans dust, soot,
pollen and spores from the air
entering the vehicle through the air
intake.
Air conditioning regular
operation
In order to ensure continuously
efficient performance, cooling must
be operated for a few minutes once a
month, irrespective of the weather
and time of year. Operation with
cooling is not possible when outside
temperature is too low.
ServiceFor optimal cooling performance, it is
recommended to annually check the
climate control system, starting
three years after initial vehicle
registration, including:
● functionality and pressure test
● heating functionality
● leakage check
● check of drive belts
● cleaning of condenser and evaporator drainage
● performance check
Driving and operating135● Close the windows.
● Turn the ignition key to position
0 and remove it. Turn the
steering wheel until the
steering wheel lock is felt to
engage.
Lock the vehicle 3 23 and activate the
anti-theft locking system 3 33 and
anti-theft alarm system 3 33.
Air suspension
Operates automatically when the
vehicle is driven. The air suspension
system constantly adjusts the ride
height according to the vehicle load.
Caution
To ensure safe operation of the air
suspension system, do not exceed the maximum permissible gross
vehicle weight rating. Refer to
identification plate 3 218 or the
vehicle documents.
For further information on the air
suspension system, refer to the
operating instructions supplied.
Master switchCaution
The air suspension system must
be switched off when the vehicle is being towed, jump‐started, raised
off the ground or transported.
Do not switch off the air
suspension system when driving.
Jump starting 3 206, Towing the
vehicle 3 208.
The master switch is located on the
door pillar.
Switch on to enable operation and
adjustment of the air suspension
system.
Switch off to put the vehicle into
service mode.
Remote control
When increased ground clearance or improved vehicle access is required,the suspension can be raised or
lowered using the remote control.
136Driving and operatingCaution
Ensure there is adequate
clearance and that there are no
obstructions when adjusting the
suspension height.
The remote control unit is magnetic
and may be fixed to any metal part of the vehicle or stored in its holder.
With the engine running, press the appropriate button for two seconds to
adjust the suspension height.
Indicator light will flash intermittently
while height adjustment is in progress
and illuminates when complete.
If the ignition is switched on with
engine not running, the suspension
height can only be lowered.
Note
Handle with care, protect from
moisture and high temperatures and
avoid unnecessary operation.
Pre-programmed settings
Adjusts the suspension height to one
of three pre-programmed positions.
l:lowered positionk:normal positionj:raised positionCaution
If an obstacle is detected while
raising or lowering, the
suspension height is returned to the normal position after a delay.
This does not guarantee damage- free operation. Ensuring sufficient
clearance and freedom from
obstacles is the responsibility of the driver.
Manual settings
Manual adjustment can only be
performed when the vehicle is
stationary.
Select by pressing h for
two seconds , then R to raise, or S to
lower.
To exit, press any of the pre-
programmed buttons.
Note
Obstacle detection is not available
during manual adjustment.
When a certain low speed is
exceeded or when the ignition is
switched off, height adjustment is deactivated automatically and the
suspension height is returned to the
normal position.
Service modeWhen the vehicle is stationary, press
i for five seconds to put the vehicle
into service mode. The indicator light
will illuminate.
When service mode has been
activated, the air suspension master
switch must be turned off.
To exit service mode, press i again
for five seconds.
Fault
If a fault is detected, i will flash
intermittently. If service mode has been activated and there is a fault, h,
S and R will flash simultaneously.
Have the cause of the fault remedied
by a workshop.
196Vehicle careRelearn function
After a puncture has been repaired
and the driver has inflated the tyres to
the correct tyre pressure, the tyre
pressure monitoring system needs to recalculate.
Tyre pressure 3 239, Tyre repair kit
3 198.
During driving, select the tyre
pressure menu in the Driver
Information Centre by pressing button
on end of wiper lever. Press and hold button for approx. five seconds to
initialise recalculation. A
corresponding message appears in
the Driver Information Centre.
Several minutes of driving at a speed above 40 km/h may be required to
complete the relearn process. The system can only provide limited
information during this time.
If problems occur during the relearn
process, control indicator w remains
illuminated and a warning message is displayed in the Driver Information
Centre.
Driver Information Centre 3 98.
Vehicle messages 3 99.
General information
The use of tyre chains or
commercially available liquid tyre
repair kits can impair the function of
the system. Factory-approved tyre
repair kits can be used.
Tyre repair kit 3 198, Tyre chains
3 197.
External high-power radio equipment
could disrupt the tyre pressure
monitoring system.
Each time the tyres are replaced, the
tyre pressure monitoring system
sensors must be dismounted and
serviced by a workshop.Tread depth
Check tread depth at regular
intervals.
Tyres should be replaced for safety
reasons at a tread depth of two-
three mm (four mm for winter tyres).
For safety reasons it is recommended
that the tread depth of the tyres on
one axle should not vary by more than two mm.
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
