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:
1. Place a suitable container underneath the fuel filter vent
screw to collect fuel.
2. Loosen the vent screw (arrowed) by one turn.
3. Manually operate the in-line supply pump slowly and steadily
until fuel discharging from the
loosened vent screw is free of air
bubbles.
4. Retighten the vent screw.
If the engine cannot be started after
several attempts to bleed the diesel
fuel system, seek the assistance of a
workshop.

148Vehicle careElectrical systemFuses
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 tank.
Before replacing a fuse, turn off the
respective switch and the ignition.
A blown fuse can be recognised by its melted wire. 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.

To help in replacing fuses, a fuse
extractor is located in the instrument
panel fuse box.
Place the fuse extractor on the
various types of fuse from the top or
side, and withdraw fuse.

7.Screw the sealant filler hose to the
tyre valve.
8. The rocker switch on the compressor must be set to
position O.9.
Connect the red < power supply
lead on the compressor to the
jump start terminal 3 160.
10. Connect the black ] power
supply lead to a vehicle grounding
point, e.g. the engine block or an
engine mounting bolt.
To avoid discharging the battery,
we recommend running the
engine.11. Set the rocker switch on the compressor to position I. The tyre
is filled with sealant.
12. The compressor pressure gauge briefly indicates up to 6 bar. Then
the pressure starts to drop.
13. All of the sealant is pumped into the tyre. Then the tyre is inflated.

not be driven. Seek theassistance of a workshop.
20. Stow tyre repair kit under the front
seat.
Notice
The driving characteristics of the repaired tyre are severely affected, therefore have this tyre replaced.
If unusual noise is heard or the
compressor becomes hot, turn
compressor off for at least
30 minutes.
The built-in safety valve opens at a
pressure of 7 bar (102 psi).
Note the expiry date of the kit. After
this date its sealing capability is no
longer guaranteed. Pay attention to
storage information on sealant
bottle.
Replace the used sealant bottle. Dispose of the bottle as prescribed
by applicable laws.
The compressor and sealant can be used from approx. -30 °C.
The adapters supplied can be used
to pump up other items e.g.
footballs, air mattresses, inflatabledinghies etc. They are located on the underside of the compressor. To
remove, screw on compressor air hose and withdraw adapter.
Wheel changing Some vehicles are equipped with a
tyre repair kit instead of a spare wheel 3 154.
Make the following preparations and
observe the following information:
■ Park the vehicle on a level, firm and
non-slippery surface. The frontwheels must be in the straight-ahead position.
■ Apply the parking brake and engage first gear or reverse gear.
■ Switch off the air suspension system 3 110.
■ Remove the spare wheel 3 159.
■ Never change more than one wheel
at a time.
■ Use the jack only to change wheels
in case of puncture, not for
seasonal winter or summer tyre
change.■ If the ground on which the vehicle is standing is soft, a solid board
(max. 1 cm thick) should be placed
under the jack.
■ No people or animals may be in the
vehicle when it is jacked-up.
■ Never crawl under a jacked-up vehicle.
■ Do not start the engine when the vehicle is raised on the jack.
■ Clean wheel bolts/nuts and their threads before mounting the wheel.9 Warning
Do not grease wheel bolt, wheel
nut and wheel nut cone.
1. Remove the wheel cover using the hook supplied. Vehicle tools
3 150.
2. Install the wheel wrench ensuring that it locates securely and loosen
each wheel bolt/nut by half a turn.

Vehicle care161Caution
The air suspension system must
be switched off prior to jump
starting.
9 Warning
Avoid contact of the battery with
eyes, skin, fabrics and painted
surfaces. The fluid contains
sulphuric acid which can cause
injuries and damage in the event
of direct contact.
■ Never expose the vehicle battery to
naked flames or sparks.
■ A discharged vehicle battery can already freeze at a temperature of
0 °C. Defrost the frozen vehicle
battery before connecting jump
leads.
■ Wear eye protection and protective
clothing when handling a vehicle
battery.
■ Use a booster battery with the same voltage (12 volts). Its capacity(Ah) must not be much less than
that of the discharged vehicle
battery.
■ Use jump leads with insulated terminals and a cross section of at
least 25 mm 2
.
■ Do not disconnect the discharged battery from the vehicle.
■ Switch off all unnecessary electrical
consumers.
■ Switch off the air suspension system.
■ Do not lean over the vehicle battery
during jump starting.
■ Do not allow the terminals of one lead to touch those of the other
lead.
■ The vehicles must not come into contact with each other during the
jump starting process.
■ Apply the parking brake, transmission in neutral.Jump start terminal
In the event of a discharged vehicle
battery, the jump start terminal
enables the vehicle to be started
without the need to access the battery inside the vehicle.
The jump start terminal is located in
the engine compartment and
identified by a " <" sign on the red
insulating cover. Lift the red insulating
cover to access the terminal
connector.
Ensure the red insulating cover is
latched back into position when not in
use.

Jump starting procedure
Lead connection order:1. Connect the red lead to the positive terminal of the booster
battery.
2. Connect the other end of the red lead to the jump start terminal of
the vehicle with the discharged
vehicle battery.
3. Connect the black lead to the negative terminal of the booster
battery.
4. Connect the other end of the black
lead to a vehicle grounding point,
such as the engine block or an
engine mounting bolt. Connect as far away from the discharged
vehicle battery as possible,
however at least 60 cm.
Route the leads so that they cannot
catch on rotating parts in the engine
compartment.
To start the engine: 1. Start the engine of the vehicle providing the jump start.
2. After 5 minutes, start the other engine. Start attempts should be
made for no longer than
15 seconds at an interval of
1 minute.
3. Allow both engines to idle for approx. 3 minutes with the leads
connected.
4. Switch on electrical consumers (e.g. headlights, heated rear
window) of the vehicle receiving
the jump start.
5. Reverse above sequence exactly when removing leads.Towing
Towing the vehicle The towing eye is stowed with thevehicle tools 3 150.
Disengage the cover using a suitable
tool and remove.
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.
Page 165 of 201

Vehicle care163Caution
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 release steering
wheel lock and to permit operation of
brake lights, horn and windscreen
wipers.
Switch off the air suspension system
3 110.
Transmission in neutral.
If neutral cannot be selected on
vehicles with MTA transmission, the vehicle must only be towed with the
drive wheels raised off the ground.
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 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.
The rear towing eye must only be
used for towing and not recovering a
vehicle.
Caution
Drive slowly. Do not drive jerkily.
Excessive tractive force can
damage the vehicle.
