Tyre pressure sensor matching
process
Each tyre pressure sensor has a
unique identification code. The
identification code must be matched
to a new wheel position after rotating the wheels or exchanging the
complete wheel set and if one or more tyre pressure sensors were replaced.
The tyre pressure sensor matching
process should also be performed
after replacing a spare wheel with a
road wheel containing the tyre
pressure 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
Vehicle care2673. Allow both engines to idle forapprox. three minutes with the
leads connected.
4. Switch on electrical consumers (e.g. headlights, heated rear
window) of the vehicle receiving
the jump start.
5. Reverse above sequence exactly when removing leads.Towing
Towing the vehicle
Insert a screwdriver in the slot at the
lower part of the cap. Release the cap
by carefully moving the screwdriver
downwards.
The towing eye is stowed with the
vehicle tools 3 249.
Screw in the towing eye as far as it will
go until it stops in a horizontal
position.
Attach a tow rope – or better still a tow
rod – to the towing eye.
The towing eye must only be used for
towing and not for recovering the
vehicle.
Switch on ignition to release steering wheel lock and to permit operation of
brake lights, horn and windscreen
wiper.
Transmission in neutral.
270Vehicle careThoroughly rinse and leather-off the
vehicle. Rinse leather frequently. Use
separate leathers for painted and
glass surfaces: remnants of wax on
the windows will impair vision.
Have the door hinges of all doors
greased by a workshop.
Do not use hard objects to remove
spots of tar. Use tar removal spray on painted surfaces.
Exterior lights
Headlight and other light covers are made of plastic. Do not use any
abrasive or caustic agents, do not use an ice scraper, and do not clean them
dry.
Polishing and waxing
Wax the vehicle regularly (at the
latest when water no longer beads).
Otherwise, the paintwork will dry out.
Polishing is necessary only if the paint
has become dull or if solid deposits
have become attached to it.
Paintwork polish with silicone forms a
protective film, making waxing
unnecessary.Plastic body parts must not be treated with wax or polishing agents.
Windows and windscreen wiper
blades
Use a soft lint-free cloth or chamois
leather together with window cleaner and insect remover.
When cleaning the rear window from
inside, always wipe in parallel to the
heating element to prevent damage.
For mechanical removal of ice, use a
sharp-edged ice scraper. Press the
scraper firmly against the glass so
that no dirt can get under it and
scratch the glass.
Remove dirt residues from smearing wiper blades by using a soft cloth and window cleaner. Also make sure to
remove any residues such as wax,
insect residues and similar from the
window.
Ice residues, pollution and continuous
wiping on dry windows will damage or
even destroy the wiper blades.Sunroof
Never clean with solvents or abrasive
agents, fuels, aggressive media
(e.g. paint cleaner, acetone-
containing solutions etc.), acidic or
highly alkaline media or abrasive
pads. Do not apply wax or polishing
agents to the sunroof.
Wheels and tyres
Do 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 with
a 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.
