Fuses
Data on the replacement fuse must match the data on the defective fuse.
There are three fuse boxes in the
vehicle:
■ in the front left of the engine compartment
■ in left-hand drive vehicles, in the interior behind the storage
compartment, or, in right-hand
drive vehicles, behind the glovebox
■ behind a cover on the left side of the
load compartment
Before replacing a fuse, turn off the
respective switch and the ignition.
A blown fuse can be recognized by its melted wire. Do not replace the fuse
until the cause of the fault has been
remedied.
Some functions are protected by
several fuses.
Fuses may also be inserted without existence of a function.
Fuse extractor
A fuse extractor may be located in the fuse box in the engine compartment.

194Vehicle careTyre pressureCheck 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 3 233.
The tyre pressure information label
on the right door frame indicates the original equipment tyres and the
correspondent tyre pressures.
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.
The ECO tyre pressure serves to
achieve the smallest amount of fuel
consumption possible.
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 3 225.
2. Identify the respective tyre.
The tyre pressure tables show all
possible tyre combinations 3 233.
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.
If the tyre pressure must be reduced
or increased on a vehicle with tyre
pressure monitoring system, switch
off ignition.
Tyre pressure monitoring system The tyre pressure monitoring system
(TPMS) checks the pressure of all
four wheels once a minute when
vehicle speed exceeds a certain limit.

196Vehicle care
If w flashes for 60-90 seconds and
then illuminates continuously, there is a fault in the system. Consult a
workshop.
After inflating, driving may be
required to update the tyre pressure
values in the DIC. 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.
Vehicle messages 3 105.
If the tyre pressure shall be reduced
or increased, switch off ignition.
Only mount wheels with pressure
sensors, otherwise the tyre pressure
will not be displayed and w
illuminates continuously.
A temporary spare wheel is not
equipped with pressure sensors. The
tyre pressure monitoring system is
not operational for these wheels.
Control indicator w illuminates. For
the further three wheels the system
remains operational.The use of commercially available
liquid tyre repair kits can impair the
function of the system. Factory-
approved repair kits can be used.
External high-power radio equipment
could disrupt the tyre pressure
monitoring system.
Each time the tyres are replaced tyre
pressure monitoring system sensors
must be dismounted and serviced. For the screwed sensor: replace
valve core and sealing ring. For
clipped sensor: replace complete
valve stem.
Vehicle loading status Adjust tyre pressure to load condition according to tyre information label or
tyre pressure chart 3 233, and select
the relevant setting in the menu Tire
Load in the Driver Information Centre,
Vehicle Information Menu 3 100.
Select:
■ Light for comfort pressure up to
3 people.
■ Eco for Eco pressure up to
3 people.
■ Max for full loading.
TPMS Sensor Matching
Process
Each TPMS sensor has a unique
identification code. The identification
code must be matched to a new tyre/
wheel position after rotating the tyres
or exchanging the complete wheel set and if one or more TPMS sensorswere replaced. The TPMS sensor
Page 199 of 247

Vehicle care197
matching process should also be
performed after replacing a spare tyre with a road tyre containing the TPMS
sensor.
The malfunction light w and the
warning message or code should go
off at the next ignition cycle. The
sensors are matched to the tyre/
wheel positions, using a TPMS
relearn tool, in the following order: left
side front tyre, right side front tyre,
right side rear tyre and left side rear
tyre. The turn light at the current
active position is illuminated until
sensor is matched.
Consult your workshop for service or
to purchase a relearn tool. There are
2 minutes to match the first tyre/wheel position, and 5 minutes overall to
match all four tyre/wheel positions. If
it takes longer, the matching process
stops and must be restarted.The TPMS sensor matching process is:
1. Apply the parking brake; on vehicles with automatic
transmission set the selector lever
to P.
2. Turn the ignition on.
3. Press MENU on the turn signal
lever to select the Vehicle
Information Menu in the Driver
Information Centre (DIC).
4. Turn the adjuster wheel to scroll to
the tyre pressure menu.
5. Press the SET/CLR button to
begin the sensor matching
process. A message requesting
acceptance of the process should
display.
6. Press the SET/CLR button again
to confirm the selection. The horn sounds twice to signal the
receiver is in relearn mode.
7. Start with the left side front tyre.
8. Place the relearn tool against the tyre sidewall, near the valve stem.Then press the button to activate
the TPMS sensor. A horn chirpconfirms that the sensor
identification code has been
matched to this tyre and wheel
position.
9. Proceed to the right side front tyre,
and repeat the procedure in Step 8.
10. Proceed to the right side rear tyre,
and repeat the procedure in
Step 8.
11. Proceed to the left side rear tyre, and repeat the procedure in
Step 8. The horn sounds twice to
indicate the sensor identification
code has been matched to the left side rear tyre, and the TPMS
sensor matching process is no
longer active.
12. Turn off the ignition.
13. Set all four tyres to the recommended air pressure level
as indicated on the tyre pressure
label.
14. Ensure the tyre loading status is set according selected pressure
3 100.

is obtained, switch off the
compressor by pressing the on/off switch again.
If the prescribed tyre pressure is
not obtained within 10 minutes,
remove the tyre repair kit. Move
the vehicle one tyre rotation.
Reattach the tyre repair kit and
continue the filling procedure for 10 minutes. If the prescribed tyre
pressure is still not obtained, the
tyre is too badly damaged. Seek
the assistance of a workshop.
Release excess tyre pressure by
pressing ].
Do not run the compressor longer
than 10 minutes.
12. Push catch on bracket to remove sealant bottle from bracket. Screwthe tyre inflation hose to the free
connection of the sealant bottle.
This prevents sealant from
escaping. Stow tyre repair kit in
load compartment.
