Accessories and vehicle
modifications
We recommend using 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
The following must be done if the
vehicle should 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 engine oil.
■ Drain washer fluid reservoir.
■ Check coolant antifreeze.
■ Adjust tyre pressure to the value specified for full load.
■ Park vehicle in dry, well ventilated place. Engage first or reverse gear
or set selector lever to P. Prevent
the vehicle from rolling.
■ Do not apply parking brake.

Tyre pressure
Check the pressure of cold tyres at
least every 14 days and before any
long journey. Do not forget the spare
wheel. This also applies to vehicles
with tyre pressure monitoring.
Remove the valve cap key from the
fuel filler flap and use it to unscrew the
valve cap.
On vehicles with tyre pressure
monitoring system, screw the adapter
to the valve.
Tyre pressure 3 225 and on the label
on the inside of the fuel filler flap.
The tyre pressure data refer to cold
tyres. It applies to summer and winter tyres.
Always inflate the spare wheel to the
pressure specified for full load.
The ECO tyre pressure serves to
achieve the smallest amount of fuel
consumption possible. It must not be used with run-flat tyres.
Incorrect tyre pressures will impair
safety, vehicle handling, comfort and
fuel economy and will increase tyre
wear.
Tyre pressures differ depending on
various options. For the correct tyre
pressure value, follow the procedure
below:
1. Identify drive axle and body style.
2. Identify the engine identifier code.
Engine data 3 216.
3. Identify the respective tyre.
