178Vehicle 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 left-hand side of the instrument panel, behind the trimpanel
● in the engine compartment located next to the battery
Notice
The engine compartment fuse box
should only be accessed by a
workshop.
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. 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.

The tyre pressure information label
on the driver's door frame indicates
the original equipment tyres and the
correspondent tyre pressures.
Always inflate tyres to the pressures
shown on the label.
Tyre pressures 3 216.
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 3 206.
2. Identify the respective tyre.
The tyre pressure tables show all
possible tyre combinations 3 216.
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.
9 Warning
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.
Temperature dependency
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.
186Vehicle careA spare wheel or temporary spare
wheel is not equipped with pressure
sensors. The tyre pressure
monitoring system is not operational
for these wheels. For the further three wheels, the tyre pressure monitoring
system remains operational.

After a puncture has been repaired
and the driver has inflated the tyres to
the correct tyre pressure, the tyre
pressure monitoring system needs to recalculate.
Tyre pressure 3 216.
Tyre repair kit 3 188.
During driving, select the tyre
pressure menu in the Driver
Information Centre by pressing button
on end of wiper lever. Press and hold button for approx. five seconds to
initialise recalculation. A
corresponding message appears in
the Driver Information Centre.
Several minutes of driving at a speed above 25 mph may be required to
complete the relearn process. The system can only provide limited
information during this time.
If problems occur during the relearn
process, control indicator w remains
illuminated and a warning message is displayed in the Driver Information
Centre.
Driver Information Centre 3 100.

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 3 188, Tyre chains
3 188.
External high-power radio equipment
could disrupt the tyre pressure
monitoring system.
Each time the tyres are replaced, the

with sealant.
10. The compressor pressure gauge briefly indicates up to six bar
(600 kPa/87 psi). Then the
pressure starts to drop.
11. All of the sealant is pumped into the tyre. Then the tyre is inflated.
Vehicle care191Notice
The driving characteristics of the
repaired tyre is severely affected, therefore have this tyre replaced.
If unusual noise is heard or the
compressor becomes hot, turn
compressor off for at least
30 minutes.
Pay attention to storage information
and expiry date on sealant bottle. Its
sealing capability is not guaranteed
after this time.

prescribed by applicable laws.
Wheel changing
Some vehicles are equipped with a
tyre repair kit instead of a spare wheel 3 188.
Make the following preparations and
observe the following information:
● Park the vehicle on a level, firm and non-slippery surface. The
front wheels must be in the
straight-ahead position.
● Apply the parking brake and engage first gear or reverse gear.● Remove the spare wheel 3 192.
● Never change more than one wheel at a time.
● Use the jack only to change wheels in case of puncture, not
for a seasonal winter or summer
tyre change.
● The jack is maintenance-free. ● If the ground on which the vehicle
is standing is soft, a solid board
(max. 1 cm thick) should be
placed under the jack.
● Remove heavy objects out of the
vehicle before jacking up.
● No people or animals may be in the vehicle when it is jacked-up.
● Never crawl under a jacked-up vehicle.
● Do not start the engine when the vehicle is raised on the jack.
● Clean wheel bolts/nuts and thread with a clean cloth before
mounting the wheel.9 Warning
