battery or before jump starting the vehicle.
The terminals are designed for
additional electrical consumers up to a maximum of 50 A.
Jump starting 3 196.
Diesel fuel filter The diesel fuel filter is accessible from
the underside of the vehicle.
Drain filter of residual water at every
engine oil change.
Place a container underneath the
filter housing. Loosen the knurled
screw on the lower part of the filter by approx. one turn, to drain off the
water.
The filter is drained as soon as water-
free diesel fuel emerges. Retighten
the screw.
Check diesel fuel filter at shorter
intervals if the vehicle is subjected to
extreme operating conditions.
Diesel fuel system bleeding
If the fuel tank has been run dry, it will be necessary to air vent or bleed the
diesel fuel system.
Refuel then proceed as follows:With ignition key
● Switch on the ignition (key to position 2) for 5 seconds at a
time.
● Switch off ignition (key to position
1 ) for 3 seconds.
● Repeat this process multiple times.
● Start the engine (key to position 3) then switch off (key to position
0 ).
Ignition switch positions 3 131.
174Vehicle careBulb replacement
Switch off the ignition and turn off the relevant switch or close the doors.
Only hold a new bulb at the base. Do
not touch the bulb glass with bare
hands.
Use only the same bulb type for
replacement.
Bulb check After a bulb replacement, switch on
the ignition, operate and check the
lights.
Headlights
Low beam and high beam Replace headlight bulbs from within
the engine compartment.
1. Remove protective cover by rotating it anticlockwise.
2. Detach wiring connector.
3. Release retaining clip (see illustration) and remove bulb.
4. Renew bulb and install retaining clip ensuring that bulb is in correct
orientation.
5. Reattach wiring connector and protective cover.
Sidelights / Daytime running lights
1. Remove protective cover byrotating it anticlockwise.
2. Release retaining clips and remove bulb holder from reflector
housing.
3. Renew bulb.
4. Install bulb holder in reflector housing and engage retaining
clips.
5. Install protective cover.

Fuses
Data on the replacement fuse must
match the data on the defective fuse.
There are two fuse boxes in the
vehicle:
● on the left-hand side of the instrument panel, behind the trim
panel
● in the engine compartment located next to the battery
Notice
The engine compartment fuse box
should only be accessed by a
workshop.
Before replacing a fuse, turn off the
respective switch and the ignition.
There are different types of fuses inthe vehicle.
Depending on the type of fuse, a
blown fuse can be recognised by its
melted wire. Do not replace the fuse
until the cause of the fault has been
remedied.
Vehicle care187Trailer towingWhen towing a trailer with a fully
laden vehicle, the tyre pressure must
be increased by 20 kPa/0.2 bar
(3.0 psi) and the maximum speed
limited to 60 mph.
Trailer towing 3 161.
Tyre pressure monitoring
system
The tyre pressure monitoring system
uses radio and sensor technology to
check tyre pressure levels.Caution
Tyre pressure monitoring system
warns only about low tyre pressure condition and does not replace
regular tyre maintenance by the
driver.
All wheels must be equipped with pressure sensors and the tyres must
have the prescribed pressure.
Notice
In countries where the tyre pressure
monitoring system is legally
required, the use of wheels without
pressure sensors will invalidate the
vehicle operating permit.
The tyre pressure monitoring system
sensors monitor the air pressure in
the tyres and transmit tyre pressure
readings to a receiver located in the
vehicle.
Tyre pressure chart 3 220.
Low tyre pressure conditionA detected low tyre pressure
condition is indicated by illumination
of control indicator w 3 99 and a
corresponding message appears in
the Driver Information Centre.
If w illuminates, stop as soon as
possible and inflate the tyres as
recommended 3 220.
After inflating, some driving may be
required to update the tyre pressure
values in the system. During this time
w may illuminate.
If w illuminates at lower temperatures
and extinguishes after some driving,
this could be an indicator for
approaching a low tyre pressure
condition. Check tyre pressure of all
four tyres.
If the tyre pressure must be reduced
or increased, switch off ignition.
Only mount wheels with pressure
sensors, otherwise w flashes for
several seconds then illuminates
continuously together with control
indicator j 3 97 and a corresponding
message appears in the Driver
Information Centre.
188Vehicle careA spare wheel or temporary spare
wheel is not equipped with pressure
sensors. The tyre pressure
monitoring system is not operational
for these wheels. For the further three wheels, the tyre pressure monitoring
system remains operational.
Control indicator w and the
corresponding message appears at
each ignition cycle until the tyres are
inflated to the correct tyre pressure.
Driver Information Centre 3 101.
Vehicle messages 3 102.
Puncture A puncture or severely under-inflated
tyre is indicated by illumination of
control indicator w together with C
3 97 and a corresponding message
appears in the Driver Information
Centre. Stop vehicle and switch off
engine.

Tyre repair kit 3 190.
Spare wheel 3 195.
Wheel changing 3 193.Relearn 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 3 220.
Tyre repair kit 3 190.
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. 5 seconds to
initialise recalculation. A
corresponding message appears in
the Driver Information Centre.
Several minutes of driving at a speed above 25 mph 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 3 101.
Vehicle messages 3 102.
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 3 190.
Tyre chains 3 190.
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.
198Vehicle careTowingTowing the vehicle
The towing eye is stowed with the
vehicle tools 3 184.
Release cap using a suitable tool.
Screw the towing eye clockwise into
the front towing point and tighten fully
using the wheel wrench.
Attach a tow rope - or better still a tow rod - to the towing eye, never to the
bumper or front suspension units.
Caution
Do not tow the vehicle from the
rear. The front towing eye must
only be used for towing and not
recovering a vehicle.
Caution
Activate the child locks in the rear
doors if the rear seats are
occupied.
Child locks 3 30.
Switch on ignition to permit operation
of brake lights, horn and windscreen
wipers, and move the steering wheel
slightly to release the steering wheel
lock.
Notice
Depending on version, it may be
necessary to switch on the engine to
permit operation of brake lights.
Move the selector lever to neutral.
Release the parking brake.
Caution
Drive slowly. Do not drive jerkily.
Excessive tractive force can
damage the vehicle.
When the engine is not running,
considerably more force is needed to
brake and steer.
Switch on hazard warning flashers
3 111.
To prevent the entry of exhaust fumes
from the towing vehicle, switch on the air recirculation system 3 117 and
close the windows.
Seek the assistance of a workshop.
After towing, unscrew the towing eye
and replace cap.
