Accessories and vehicle
modifications
We recommend the use of 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).
Vehicle storage Storage for a long period of time
If the vehicle is to 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 the engine oil.
■ Drain the washer fluid reservoir.
■ Check the coolant antifreeze and corrosion protection.
■ Adjust tyre pressure to the value specified for full load.
■ Park vehicle in a dry, well ventilated
place. Engage first or reverse gear. Prevent the vehicle from rolling.
■ Do not apply the parking brake.
■ Open the bonnet, close all doors and lock the vehicle.
■ Disconnect the clamp from the negative terminal of the vehicle
battery. Beware that all systems are
not functional, e.g. anti-theft alarm
system.
Putting back into operation When the vehicle is to be put back into
operation:
■ Connect the clamp to the negative terminal of the vehicle battery.
Activate the electronics of the
power windows.
■ Check tyre pressure.
Vehicle care123
Place a container underneath the
filter housing. Loosen the knurled
screws on the filter cover and on the
lower part of the filter by approx. one
turn, to drain off the water.
The filter is drained as soon as diesel fuel emerges from the knurled screw
at the bottom. Retighten the two
screws.
Check diesel fuel filter at shorter
intervals if the vehicle is subjected to
extreme operating conditions.
Diesel fuel system
bleedingIf 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. Remove the protective cover from
the in-line supply pump.
2. Place a suitable container underneath the fuel filter vent
screw to collect fuel.
3. Loosen the vent screw (arrowed) by one turn.
4. Manually operate the in-line supply pump slowly and steadily
until fuel discharging from the
loosened vent screw is free of air
bubbles.
5. Retighten the vent screw.
6. Refit the protective cover to the in-
line supply pump.Wiper blade replacement

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 the
vehicle tools 3 131.
Screw the towing eye fully into the
front towing point.
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 23.
Switch on ignition to release steering
wheel lock and to permit operation of
brake lights, horn and windscreen
wipers.
Transmission in neutral.
If neutral cannot be selected on
vehicles with manual transmission automated, the vehicle must only betowed with the drive wheels raised off the ground.
142Vehicle careCaution
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.
Towing another vehicle
The fixed towing eye is located under the rear bumper.
Vehicles with a towing hitch have a
socket for the detachable towing eye.
Screw the towing eye, supplied with
the vehicle tools, fully into the socket.
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.
Vehicle care143Appearance care
Exterior care
Locks The locks are lubricated at the factoryusing a high quality lock cylinder
grease. Use de-icing agent only when
absolutely necessary, as this has a
degreasing effect and impairs lock function. After using de-icing agent,
have the locks regreased by a
workshop.
Washing The paintwork of your vehicle is
exposed to environmental influences.
Wash and wax your vehicle regularly.
When using automatic vehicle
washes, select a programme that
includes waxing.
Bird droppings, dead insects, resin,
pollen and the like should be cleaned off immediately, as they contain
aggressive constituents which can
cause paint damage.If using a vehicle wash, comply with
the vehicle wash manufacturer's
instructions. The windscreen wipers
and rear window wiper must be
switched off. Remove antenna and
external accessories such as roof
racks etc.
If you wash your vehicle by hand,
make sure that the insides of the
wheel housings are also thoroughly
rinsed out.
Clean edges and folds on opened
doors and the bonnet as well as the
areas they cover.Caution
Always use a cleaning agent with
a pH value of 4 to 9.
Do not use cleaning agents on hot surfaces.
Have the door hinges of all doors
greased by a workshop.
Do not clean the engine compartment with a steam-jet or high-pressure jet
cleaner.
Thoroughly rinse and leather-off the vehicle. Rinse leather frequently. Use
separate leathers for painted and
glass surfaces: remnants of wax on
the windows will impair vision.
Exterior lights
Headlight and other light covers are
made of plastic. Do not use any
abrasive or caustic agents, do not use an ice scraper, and do not clean them
dry.
Polishing and waxing Wax the vehicle regularly (at the
latest when water no longer beads).
Otherwise, the paintwork will dry out.
Polishing is necessary only if the paint
has become dull or if solid deposits
have become attached to it.
Paintwork polish with silicone forms a
protective film, making waxing
unnecessary.
Plastic body parts must not be treated with wax or polishing agents.
144Vehicle care
Windows and windscreen wiperblades
Use a soft lint-free cloth or chamois leather together with window cleanerand insect remover.
When cleaning the rear window from
inside, always wipe in parallel to the
heating element to prevent damage.
For mechanical removal of ice, use a
sharp-edged ice scraper. Press the
scraper firmly against the glass so
that no dirt can get under it and
scratch the glass.
Clean smearing wiper blades with a
soft cloth and window cleaner.
Wheels and tyres
Do not use high-pressure jet
cleaners.
Clean rims with a pH-neutral wheel
cleaner.
Rims are painted and can be treated
with the same agents as the body.Paintwork damage
Rectify minor paintwork damage with
a touch-up pen before rust forms.
Have more extensive damage or rust
areas repaired by a workshop.
Underbody
Some areas of the vehicle underbody
have a PVC undercoating while other critical areas have a durable
protective wax coating.
After the underbody is washed, check
the underbody and have it waxed if
necessary.
Bitumen/rubber materials could
damage the PVC coating. Have
underbody work carried out by a
workshop.
Before and after winter, wash the
underbody and have the protective
wax coating checked.
Engine compartment
It is advisable to wash the engine compartment before and after winter
and preserve it with wax. Protect thealternator and brake fluid reservoir
with plastic sheets before washing
the engine.
When washing the engine with a
steam-jet cleaner, do not direct the
steam jet towards components of the
antilock brake system, air
conditioning system or the belt drive and its components.
After an engine wash, have all engine
compartment components preserved
thoroughly by a workshop using
protective wax.
Do not use high-pressure jet
cleaners.
Towing equipment
Do not clean the coupling ball bar with a steam-jet or high-pressure jet
cleaner.
Interior care Interior and upholstery
Only clean the vehicle interior,
including the instrument panel fascia
and panelling, with a dry cloth or
interior cleaner.
