box
The fuse box is behind a cover. Press
the locking tabs forward and remove
the cover.
Do not store any objects behind the
cover.
Depending on the equipment, there
are two different fuse boxes.
Fuse box version A
To replace a fuse, remove the
relevant protective cap.
176Vehicle care
The tyre pressure tables show allpossible tyre combinations 3 206.
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
continually checks the pressure of all
four wheels when vehicle speed
exceeds a certain limit.
All wheels must be equipped with
pressure sensors and the tyres must
have the prescribed pressure.
When a low tyre condition is detected,
A illuminates. If A comes on, stop as
soon as possible and inflate the tyres as recommended in this manual. Tyre pressures 3 206.
After inflating the tyres to the
appropriate pressure, A may stay
illuminated. Pressure change will be
recognized as the vehicles is driven.
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 current tyre pressures may be
shown in the Info-Display 3 107.
Vehicle messages, tyre pressure 3 102.
Control indicator w 3 91.
If the tyre pressure shall be reduced
or increased, switch off ignition.
w may come on in cool weather when
the vehicle is first started and then
turn off as the vehicle is driven. Thiscould be an early indicator that the air
pressure is getting low and needs to
be inflated to the proper pressure.
A spare or temporary spare wheel is
not equipped with pressure sensors.
The tyre pressure monitoring system
is not operational for these wheels
and w illuminates.
Winter tyres or additional wheel sets
have to be fitted with sensors,
otherwise the system will not work
and w will indicate malfunction by
flashing one minute and then
illuminate continuously.
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.
Unsuited rims can impair the
transmission quality of the tyre
pressure monitoring system sensors.
Vehicle care177
Each time the tyres are replaced, the
tyre pressure monitoring system
sensors have to be dismounted and
serviced. For the screwed sensor
replace the valve core and sealing
ring, for the clipped sensor replace
complete rubber valve stem.
Auto learn function After changing wheels the vehicle
must be stationary for approx.
20 minutes, before the system
recalculates. The following relearn
process takes up to 10 minutes of
driving with a minimum speed of
25 km/h. ---- can be displayed in the
Info-display or pressure values can
swap.
If problems occur during the relearn
process, w will flash and then
illuminate continously.Temperature dependency
Cold tyres decrease the tyre
pressure, warm tyres increase the
tyre pressure. During driving tyre
temperature and pressure increase.
The displayed tyre pressure value
shows the actual tyre pressure.
Therefore it is important to check tyre
pressure with cold tyres.
System initialisation
After a wheel change or tyre pressure
adjustment, the system must be
initialised: inflate the cold tyres to the
prescribed pressure according to the
tyre information label or this
document 3 206. Then switch on
ignition and press and hold the DDS
button for approx. 4 seconds. w
flashes three times.
If the tyre pressure difference
between the left and the right wheel
on one axle is more than 30 kPa, tyre
pressure monitoring system
malfunction will be indicated, as the vehicle starts moving for the first time after initialisation. Adjust the tyre
pressure and repeat initialisation.
Notice
The system needs to be initialised
after tyre pressure change,
otherwise it will not be able to warn
properly.
Tread depth
Check 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).
Vehicle care191
Wheels and tyresDo not use high-pressure jet
cleaners.
Clean rims with a pH-neutral wheel
cleaner.
Rims are painted and can be treated
with the same agents as the body.
Paintwork damageRectify minor paintwork damage witha touch-up pen before rust forms.
Have more extensive damage or rust
areas repaired by a workshop.
Underbody Some areas of the vehicle underbody
have a PVC undercoating while other critical areas have a durable
protective wax coating.
After the underbody is washed, check
the underbody and have it waxed if
necessary.
Bitumen/rubber materials could
damage the PVC coating. Have
underbody work carried out by a
workshop.Before and after winter, wash the
underbody and have the protective
wax coating checked.
Engine compartment
Areas of the engine compartment that
are painted in the same colour as the vehicle must be looked after like any
other painted surface.
It is advisable to wash the engine
compartment before and after winter
and preserve it with wax. Protect the
alternator and brake fluid reservoir
with plastic sheets before washing
the engine.
When washing the engine with a
steam-jet cleaner, do not direct the
steam jet towards components of the
antilock brake system, air
conditioning system or the belt drive
and its components.
After an engine wash, have all engine
room components preserved
thoroughly by a workshop using
protective wax.
Do not use high-pressure jet
cleaners.Towing equipment
Do not clean the coupling ball bar with
a steam-jet or high-pressure jet
cleaner.
Interior care Interior and upholsteryOnly clean the vehicle interior,
including the instrument panel fascia
and panelling, with a dry cloth or
interior cleaner.
Clean the leather upholstery with
clear water and a soft cloth. In case of
heavy soiling, use leather care.
The instrument cluster and the
displays should only be cleaned using
a soft damp cloth. If necessary use a
weak soap solution.
Clean fabric upholstery with a
vacuum cleaner and brush. Remove
stains with an upholstery cleaner.
194Service and maintenance
Fixed service interval
When service is due, InSP appears in
the service display for approx.
10 seconds when the ignition is
switched on. Have the next service
performed by a workshop within
one week or 500 km (whichever
occurs first).
Flexible service interval
The service interval is based on
several parameters depending on
usage and is calculated using these
parameters.
If the remaining distance is less than
1500 km, InSP is displayed with a
remaining distance of 1000 km when
the ignition is switched on and off. If
less than 1000 km remain, InSP is
displayed for several seconds. Have
the next service performed by a
workshop within one week or
500 km (whichever occurs first).Display of remaining distance:
1. Switch off ignition.
2. Briefly press the trip odometer reset button. The odometer
reading is shown.
3. Press and hold the reset button for
about 2 seconds. InSP and the
remaining distance are displayed.Recommended fluids,
lubricants and parts
Recommended fluids and
lubricants Only use products that meet therecommended specifications.
Damage resulting from the use of
products not in line with these
specifiations will not be covered by
the warranty.9 Warning
Operating materials are
hazardous and could be
poisonous. Handle with care. Pay
attention to information given on
the containers.
Engine oil
Engine oil is identified by its quality
and its viscosity. Quality is more
important than viscosity when
selecting which engine oil to use. The oil quality ensures e.g. engine
cleanliness, wear protection and oil
