A blown fuse can be recognised by itsmelted 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.
Notice
Not all fuse box descriptions in this
Owner's Manual may apply to your
vehicle. Refer to the fuse box label,
where fitted.
Fuse extractor
To help in replacing fuses, a fuse
extractor may be used.

152Vehicle care
Place the fuse extractor on the
various types of fuse from the top or
side, and withdraw fuse.
Instrument panel fuse box
The fuse box is located on the left-
hand side of the instrument panel, behind a trim panel.
Pull upper part of trim panel and
remove to access the fuse box.
Do not store any objects behind this
panel.
Some circuits may be protected by
several fuses.

156Vehicle careWheels and tyres
Tyre 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.
We recommend not swapping the
front wheels with the rear wheels and vice versa, as this can affect vehicle
stability. Always use less worn tyres on the rear axle.
Tyres Factory-fitted tyres are matched to
the chassis and offer optimum driving
comfort and safety.Winter tyres
Winter tyres improve driving safety attemperatures 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 designations
E.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 mph
Directional tyres
Fit directional tyres such that they rollin the direction of travel. The rolling
direction is indicated by a symbol
(e.g. an arrow) on the sidewall.
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 system.
Page 159 of 203

Vehicle care157
Tyre pressures 3 190. 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.
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 the engine identifier code.
Engine data 3 180.
2. Identify the respective tyre.
The tyre pressure tables show all
possible tyre combinations 3 190.
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 (TPMS) uses radio and
sensor technology to check tyre
pressure levels.
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.
The TPMS sensors monitor the air
pressure in the tyres and transmit tyre pressure readings to a receiver
located in the vehicle.
Tyre pressures in display The current tyre pressures can be
shown in the Driver Information
Centre 3 88.

158Vehicle care
With the vehicle stationary, press
button on end of wiper lever
repeatedly until the tyre pressure
menu is displayed.
Low tyre pressure condition
A detected low tyre pressure
condition is indicated by illumination
of control indicator w 3 86 and a
corresponding message appears in
the Driver Information Centre.
If w illuminates, stop as soon as
possible and inflate the tyres as
recommended 3 190.
After inflating, some driving may be
required to update the tyre pressure
values in the Driver Information
Centre. During this time w may
illuminate.
If w illuminates at lower temperatures
and extinguishes after some driving,
this could be an indicator for getting low pressure. Check tyre pressure.
If the tyre pressure must be reduced
or increased, switch off ignition.
Only mount wheels with pressure
sensors, otherwise the tyre pressure
will not be displayed and w flashes for
several seconds then illuminates continuously together with control
indicator A 3 84 and a
corresponding message appears in
the Driver Information Centre.
A spare wheel or temporary spare
wheel is not equipped with pressure
sensors. TPMS is not operational for these wheels. For the further three
wheels, TPMS remains operational.
Control indicator w and the
corresponding message appears at
each ignition cycle until the tyres are
inflated to the correct tyre pressure.
