180Vehicle careElectrical systemFuses
Data on the replacement fuse must
match the data on the defective fuse.
There are two fuse boxes in the
vehicle:
● in the front left of the engine compartment,
● in left-hand drive vehicles behind
the light switch, or, in right-handdrive vehicles, behind the
glovebox.
Before replacing a fuse, turn off the
respective switch and the ignition.There are different kinds of fuses in
the vehicle.
Depending on the type of fuse, 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 extractorA fuse extractor may be located in the
fuse box in the engine compartment.
Place the fuse extractor on the
various types of fuse from the top, and withdraw fuse.

The fuse box is located at the front left
of the engine compartment.
Disengage the cover and fold it
upwards until it stops. Remove the

190Vehicle careEach time the tyres are replaced, tyrepressure monitoring system sensors
must be dismounted and serviced. For the screwed sensor; replace
valve core and sealing ring. For the
clipped sensor; replace complete
valve stem.
Vehicle loading status
Adjust tyre pressure to load condition according to the tyre information labelor tyre pressure chart 3 226, and
select the appropriate setting in the menu Tyre Load in the Driver
Information Centre, Vehicle
Information Menu 3 89 . This setting is
the reference for the tyre pressure
warnings.
The Tyre Load menu only appears if
the vehicle is at a standstill and the
parking brake is applied. On vehicles
with automatic transmission the
selector lever has to be in P.
Select:
● Light for comfort pressure up to
3 people.
● Eco for Eco pressure up to
3 people.
● Max for full loading.
Tyre pressure 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 sensors
were replaced. The TPMS sensor
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 wheel
positions, using a relearn tool, in the
following order: left side front wheel,
right side front wheel, right side rear
wheel and left side rear wheel. The
turn signal light at the current active
position is illuminated until sensor is
matched.
Consult a workshop for service. There
are two minutes to match the first
wheel position, and five minutes
overall to match all four wheel
positions. If it takes longer, the
matching process stops and must be
restarted.
The tyre pressure sensor matching
process is:
1. Apply the parking brake.
2. Turn the ignition on.
3. On vehicles with manual transmission automated: Press

6.Unscrew valve cap from defective
tyre.
7. Screw the filler hose to the tyre valve.
8. The switch on the compressor must be set to J.
9. Connect the compressor plug to the power outlet or cigarette
lighter socket.
To avoid discharging the battery,
we recommend running the
engine.10. Set the rocker switch on the compressor to I. The tyre is filled
with sealant.
11. The compressor pressure gauge briefly indicates up to six bar
whilst the sealant bottle is
emptying (approx. 30 seconds).
Then the pressure starts to drop.
12. All of the sealant is pumped into the tyre. Then the tyre is inflated.
13. The prescribed tyre pressure should be obtained within ten
minutes. Tyre pressure 3 226.
When the correct pressure is
obtained, switch off the
compressor.If the prescribed tyre pressure is
not obtained within ten minutes,
remove the tyre repair kit. Move
the vehicle one tyre rotation.
Reattach the tyre repair kit and
continue the filling procedure for ten minutes. If the prescribed tyre
pressure is still not obtained, the
tyre is too badly damaged. Seek
the assistance of a workshop.
Drain excess tyre pressure with
the button over the pressure
indicator.
Do not run the compressor for
longer than ten minutes.

Vehicle care197Wheel changing
Make the following preparations and observe the following information:
● Park the vehicle on a level, firm and non-skid surface. The front
wheels must be in the straight- ahead position.
● Apply the parking brake and engage first gear or reverse gear.
● Never change more than one wheel at once.
● Use the jack only to change wheels in case of puncture, not
for 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.
● Take 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 vehicle when it is
raised on the jack.
● Before screwing in the wheel bolts, clean them and lightly coat
the taper of each wheel bolt with
commercially available grease.9 Warning
Do not grease the thread of the
wheel bolt.
1. Steel wheels:
Pull off the wheel cover.
Alloy wheels with bolt caps Disengage wheel bolt caps with a
screwdriver and remove. To
protect the wheel, place a soft
cloth between the screwdriver
and the alloy wheel.
Alloy wheels with centre cap
Two versions are available:1.1. Insert extractor in the open
slot of the centre cap and remove the cap from the wheel. Vehicle
tools 3 185.
1.2. Insert extractor in the hole of
the centre cap and withdraw the
