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).Caution
When transporting the vehicle on
a train or on a recovery vehicle, the
mud flaps might be damaged.
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.
■ Change engine oil.
■ Drain washer fluid reservoir.
■ Check 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 parking brake.

138Vehicle care
Pull out the dipstick, wipe it clean,insert it to the stop on the handle, pull
out and read the engine oil level.Caution
It is the owner's responsibility to
maintain the proper level of an
appropriate quality oil in the
engine.
When the engine oil level has
dropped to the MIN mark, top up
engine oil.
Caution
Do not allow the engine oil level to drop below the minimum level!
We recommend the use of the same
type of engine oil that was used at the
last change.
The engine oil level must not exceed the maximum mark MAX on the
dipstick.
Caution
Overfilled engine oil must be
drained or suctioned out.
A stabilization of the engine oil
consumption will not take place until
the vehicle has been driven several
thousand miles. Only then can the
actual degree of consumption be
established.
If consumption exceeds more than
0.5 litres every 600 miles after this
running-in period, consult a
workshop.
Capacities 3 197, Engine oil level
monitor 3 75.
Fit the cap on straight and tighten it.
Engine coolant The coolant provides freeze
protection down to approx. -28 °C.
Caution
Only use approved antifreeze.

Vehicle care143Diesel fuel filter
Drain diesel fuel filter of residual
water at every engine oil change.
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
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.

3. Vehicles with Front-wheel drive:Raise vehicle by placing lifting
pad spigot of the jack under the
jacking hole located nearest the
wheel concerned.
Ensure the jack is positioned
correctly. The jack base must be
on the ground directly below the
jacking hole in a manner that
prevents it from slipping.
Attach wheel wrench onto the jack
and raise the vehicle by turning
the wrench until the wheel is clear of the ground.
Vehicles with Rear-wheel drive:
Pay attention to the operating
instructions supplied with the
hydraulic jack and assemble the
parts required as specified.
Position the adapter at the jacking
hole located nearest the wheel
concerned.
Ensure the jack is positioned
correctly. The jack head must be
level with the jacking hole. Pump
the jack by pressing the wheel
wrench, to position the base plate
correctly.
Raise the vehicle by pressing the wheel wrench until the wheel is
clear of the ground.
4. Unscrew wheel bolts/nuts completely and wipe clean with a
cloth.
Put wheel bolts/nuts somewhere
where the threads will not be
soiled.
5. Change the wheel.
6. Screw in the wheel bolts/nuts.
7. Lower vehicle.
8. Install the wheel wrench ensuring that it locates securely and tighten
each wheel bolt/nut in a crosswise sequence. Tightening torque is:
172 Nm (Front-wheel drive),
235 Nm (Rear-wheel drive with
