Fuses
Data on the replacement fuse must match the data on the defective fuse.
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. Provision is made in the fuse
box for the storing of spare fuses.
Some functions are protected by
several fuses.
Fuses may also be inserted without
existence of a function.

Vehicle care149Wheels and tyresTyre condition, wheel condition
Drive over edges slowly and at right
angles if possible. Driving over sharp
edges can cause tyre and wheel
damage. Do not trap tyres on the kerb
when parking.
Regularly check the wheels for
damage. Seek the assistance of a
workshop in the event of damage or
unusual wear.
Tyres Factory-fitted tyres are matched tothe chassis and offer optimum driving comfort and safety.
Winter tyres Winter tyres improve driving safety at
temperatures below 7 °C and should
therefore be fitted on all wheels.In accordance with country-specific
regulations, a notice indicating the
maximum permissible speed for the
tyres must be affixed within the
driver's field of vision.
Tyre designationsE.g. 195/65 R 16 C 88 Q195=Tyre width, mm65=Cross-section ratio (tyre
height to tyre width), %R=Belt type: RadialRF=Type: RunFlat16=Wheel diameter, inchesC=Cargo or commercial use88=Load index e.g. 88 is
equivalent to 567 kgQ=Speed code letter
Speed code letter:
Q=up to 100 mphS=up to 112 mphT=up to 118 mphH=up to 130 mphV=up to 150 mphW=up to 168 mphTyre 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 system.
Tyre pressures 3 178. Always inflate
tyres to the pressures shown on the
label on the driver's door frame.
The tyre pressure data refers to cold
tyres. It applies to summer and winter tyres.
Always inflate the spare tyre to the
pressure specified for full load.

150Vehicle care
Incorrect tyre pressures will impair
safety, vehicle handling, comfort and
fuel economy and will increase tyre
wear.
The tyre pressure tables show all
possible tyre combinations 3 178.
For the tyres approved for your
vehicle, refer to the EEC Certificate of Conformity provided with your vehicle
or other national registration
documents.
The driver is responsible for correct
adjustment of tyre pressure.9 Warning
If the pressure is too low, this can
result in considerable tyre warm-
up and internal damage, leading to tread separation and even to tyre
blow-out at high speeds.
Tyre pressure monitoring
system
The tyre pressure monitoring system
checks the pressure of all four wheels once a minute when vehicle speed
exceeds a certain limit.Caution
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.
Notice
In countries where the tyre pressure
monitoring system is legally
required, the use of wheels without
pressure sensors will invalidate the
vehicle type approval.
Tyre pressures in display
The current tyre pressures can be
shown in the Driver Information
Centre 3 86.
With the vehicle stationary, press
button on end of wiper lever
repeatedly until the tyre pressure
menu is displayed.
