154Vehicle careElectrical systemFuses
Data on the replacement fuse must
match the data on the defective fuse.
There are two fuse boxes in the
vehicle:
● on the right of the engine compartment, next to the vehicle
battery
● in left-hand drive vehicles; on the
left-hand side of the instrument
panel or, in right-hand drive
vehicles; on the right-hand side
of the instrument panel, behind a
cover
Before replacing a fuse, turn off the
respective switch and the ignition.
There are different types of fuses in
the vehicle.
Depending on the type of fuse, 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.
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
Use a fuse extractor to remove fuses.

could reduce the maximum speed of
the vehicle.
Performance 3 185.
Directional tyres
Directional tyres must be mounted so
that they rotate in the correct
direction. The proper rotation
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.
Unscrew the valve cap.
Tyre pressure 3 190.
The tyre pressure information label
on the door frame (if fitted) indicates the original equipment tyres and the
correspondent tyre pressures.
Always inflate tyres to the pressures
shown on the label.
The tyre pressure data refers to cold
tyres. It applies to summer and winter
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 the engine identifier code.
Engine data 3 182.
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 pressures.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.
160Vehicle care9Warning
For specific tyres the
recommended tyre pressure as
shown in the tyre pressure table may exceed the maximum tyre
pressure as indicated on the tyre.
Never exceed the maximum tyre
pressure as indicated on the tyre.
If the tyre pressure must be reduced
or increased on a vehicle with tyre
pressure monitoring system, switch
off ignition.
Temperature dependency
The tyre pressure depends on the
temperature of the tyre. During
driving, tyre temperature and
pressure increase. Tyre pressure
values provided on the tyre
information label and tyre pressure
chart are valid for cold tyres, which means at 20 °C.
The pressure increases by nearly
1.5 psi for a 10 °C temperature
increase. This must be considered
when warm tyres are checked.
Tyre pressure monitoring
system
The tyre pressure monitoring system
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.
The tyre pressure monitoring system sensors monitor the air pressure in
the tyres and transmit tyre pressure
readings to a receiver located in the
vehicle.
All wheels must be equipped with
pressure sensors and the tyres must
have the prescribed pressure.
Tyre pressure chart 3 190.
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.
Low tyre pressure condition
A detected low tyre pressure
condition is indicated by illumination
of control indicator w 3 86 together
with a warning chime. In vehicles with Multifunction version of the Driver
Information Centre, a corresponding message is also displayed.
Vehicle care161If w illuminates, stop as soon as
possible and inflate the tyres as
recommended 3 190.
After inflating, driving may be
required to update the tyre pressure
values in the system. During this time
w may illuminate.
If w illuminates at lower temperatures
and extinguishes after some driving,
this could be an indicator for
approaching a low tyre pressure
condition. Check tyre pressure of all
four tyres.
If the tyre pressure must be reduced
or increased, switch off ignition.
Only mount wheels with pressure
sensors, otherwise the tyre pressure
value cannot be recognised by the
system and w flashes for several
seconds then illuminates
continuously. In vehicles with
Multifunction version of the Driver
Information Centre, a corresponding message is also displayed.
A spare wheel or temporary spare
wheel is not equipped with pressure
sensors. The tyre pressure
monitoring system is not operationalfor these wheels. For the further three
wheels, tyre pressure monitoring
system remains operational.
Spare wheel 3 167, Wheel changing
3 165.
Control indicator w and (depending
on version) a corresponding message appears at each ignition cycle until
the tyres are inflated to the correct
tyre pressure.
Driver Information Centre 3 89.
Relearn function
After changing wheels, the tyre
pressure monitoring system needs to recalculate. The relearn process
takes up to 20 minutes of driving with
a minimum speed of 12 mph.
If problems occur during the relearn
process, control indicator w flashes
for several seconds then illuminates
continuously and (depending on
version) a warning message is
displayed in the Driver Information
Centre.
Driver Information Centre 3 89.General information
The use of tyre chains or
commercially available liquid tyre
repair kits can impair the function of
the system. Factory-approved tyre
repair kits can be used.
Tyre repair kit 3 163, Tyre chains
3 162.
Operating electronic devices or being close to facilities using similar wave
frequencies could disrupt the tyre
pressure monitoring system.
Each time the tyres are replaced, tyre
pressure monitoring system sensors
must be dismounted and serviced by
a workshop.
Tread depthCheck tread depth at regular
intervals.
Tyres should be replaced for safety
reasons at a tread depth of 2-3 mm (4 mm for winter tyres).
For safety reasons, it is
recommended that the tread depth of
the tyres on one axle should not vary
by more than 2 mm.
162Vehicle care
The legally permissible minimum
tread depth (1.6 mm) has been
reached when the tread has worn
down as far as one of the tread wear
indicators (TWI). Their position is
indicated by markings on the
sidewall.
If there is more wear at the front than
the rear, swap round front wheels and rear wheels periodically. Ensure that
the direction of rotation of the wheels
is the same as before.
Tyres age, even if they are not used.
We recommend tyre replacement
every six years.
Changing tyre and wheel
size
If tyres of a different size than those
fitted at the factory are used, it may be necessary to reprogramme the
speedometer as well as the nominal
tyre pressure and make other vehicle
modifications.
After converting to a different tyre
size, have the label with tyre
pressures replaced.9 Warning
Use of unsuitable tyres or wheels
may lead to accidents and will
invalidate the vehicle type
approval.
Wheel covers
Wheel covers and tyres that are
factory approved for the respective
vehicle and comply with all of the
relevant wheel and tyre combination requirements must be used.
If the wheel covers and tyres used are
not factory approved, the tyres must
not have a rim protection ridge.
Wheel covers must not impair brake
cooling.9 Warning
Use of unsuitable tyres or wheel
covers could lead to sudden
pressure loss and thereby
accidents.
Tyre chains
Tyre chains are only permitted on the
front wheels.
Vehicle care16710. Align the valve hole in the wheelcover with the tyre valve before
installing.
Install wheel nut caps.
11. Stow the replaced wheel 3 167
and the vehicle tools 3 158.
12. Check the tyre pressure of the installed tyre and the wheel nut
torque as soon as possible.
Have the defective tyre renewed or repaired as soon as possible.
Spare wheel Some vehicles are equipped with a
tyre repair kit 3 163 instead of a spare
wheel.
If mounting a spare wheel which is
different from the other wheels, this
wheel might be classified as a
temporary spare wheel and the
corresponding speed limits apply,
even though no label indicates this.
Seek the assistance of a workshop to
check the applicable speed limit.Caution
The use of a spare wheel that is smaller than the other wheels or in combination with winter tyres
could affect driveability. Have the defective tyre replaced as soon as
possible.
Depending on model variant, the
spare wheel is stored beneath the
floor or in the load compartment.
1. Attach the extension bar 2 to the
wheel wrench 1. Vehicle tools
