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.
Fill the tank with fuel and proceed as
follows:Caution
Do not turn ignition key to position 3 before beginning the bleeding
procedure.
Ignition switch positions 3 226.
1. Turn ignition key to position 2 and
wait for a few minutes.
2. Turn key back to position 1 and
wait for 3 seconds.
3. Turn key to position 3.
Vehicle care277If the engine cannot be started after
several attempts to bleed the diesel
fuel system, seek the assistance of a
workshop.
Wiper blade replacement Wiper blades on the windscreen
If required, use the step located below
the headlights to reach the
windscreen wiper.
Lift wiper arm, press retaining clip
towards wiper arm and detach wiper
blade.
Attach the wiper blade slightly angled
to the wiper arm and push until it
engages.
Lower wiper arm carefully.Bulb replacement
Ensure the ignition is switched off
completely (the vehicle must not be in
an Autostop 3 228) 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.
Have additional lighting bulbs of the
body conversions replaced by a
workshop.
Bulb check
After a bulb replacement, switch on
the ignition, operate and check the
lights.
Performing work 3 270.
Vehicle care285Instrument panel
illumination
Have bulbs replaced by a workshop.Electrical system
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 below the coolant
expansion tankCombi
An additional fuse box is located
behind a trim panel on the right-hand
side of the load compartment, beside the rear door.Bus
An additional fuse box is located on
the lower right-hand side of the load
compartment, below the step trim
panel.
Before replacing a fuse, turn off the
respective switch and the ignition.
A blown fuse can be recognised by its melted wire.
Caution
Do not replace the fuse until the
cause of the fault has been
remedied.
It is advisable to carry a full set of
fuses. Consult a workshop.
Some functions are protected by
several fuses.
Fuses may also be inserted without
existence of a function.
Note
Not all fuse box descriptions in this
manual may apply to your vehicle.
When inspecting the fuse box, refer
to the fuse box label.
Fuse extractor
A fuse extractor may be located in the
instrument panel fuse box. The
extractor has two sides, each side is
designed for a different type of fuses.
Vehicle care293Caution
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.
Note
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 tyre pressure
and transmit tyre pressure readings
to a receiver located in the vehicle.
Tyre pressure chart 3 317.
Low tyre pressure condition
A detected low tyre pressure
condition is indicated by illumination
of control indicator w 3 102 and a
corresponding message appears in
the Driver Information Centre.
If w illuminates, stop as soon as
possible and inflate the tyres as
recommended 3 317.
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
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 99 and a
corresponding message appears in
the Driver Information Centre.
A 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 other
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 3 105.
Vehicle messages 3 106.
Vehicle care307Caution
Do not tow the vehicle from the
rear. The front towing eye must
only be used for towing and not
recovering a vehicle.
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.
Switch off the air suspension system 3 231.
Caution
Deactivate the driver assistance
systems like active emergency
braking 3 253, otherwise the
vehicle may automatically brake during towing.
Move the selector lever to neutral.
Release the parking brake.
Caution
Vehicles with manual
transmission automated: If neutral cannot be selected, the vehiclemust only be towed with the drive
wheels raised off the ground.
The vehicle should always be
towed with the ignition switched
off.
Manual transmission automated
3 241.
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.
To prevent the entry of exhaust fumes
from the towing vehicle, switch on the air recirculation system 3 209 and
close the windows.
Seek the assistance of a workshop.
After towing, unscrew the towing eye
and refit the cover.
Towing another vehicle
Attach a tow rope – or better still a tow
rod – to the rear towing eye, never to
the rear axle and suspension units.
Caution
The rear towing eye must only be
used for towing and not recovering a vehicle.
