5. Switch off the engine by turning the start
knob in the tunnel console to STOP. Hold
the knob in STOP position for at least
4 seconds.
> The car is ready for the automatic car
wash.
IMPORTANT
The system will automatically switch to P
mode unless the above step is followed. The
wheels are locked in P mode, which they
should not be when putting the car through
an automatic car wash.
High-pressure washing
When using high-pressure washing, use sweep-
ing movements and make sure that the nozzle
does not come closer than 30 cm to the surface
of the car (the distance applies to all exterior
parts). Do not spray directly onto the locks.
Testing the brakes
Lightly depress the brake pedal now and then
when driving long distances in rain or slush. The
heat from the friction causes the brake linings to
warm up and dry. Do the same thing after starting
in very damp or cold weather.
WARNING
Always test the brakes after washing the car,
including the parking brake, to ensure that
moisture and corrosion do not attack the
brake linings and reduce braking perform-
ance.
Wiper blades
Asphalt, dust and salt residue on wiper blades, as
well as insects, ice etc. on the windscreen, impair
the service life of wiper blades.
When cleaning, set the wiper blades in service
position.
NOTE
Wash the wiper blades and windscreen regu-
larly with lukewarm soap solution or car
shampoo. Do not use any strong solvents.
Exterior plastic, rubber and trim
components
A special cleaning agent available from Volvo
dealers is recommended for the cleaning and
care of coloured plastic parts, rubber and trim
components, e.g. glossy trim mouldings. When
using such a cleaning agent the instructions
must be followed carefully.
MAINTENANCE AND SERVICE
IMPORTANT
Avoid waxing and polishing on plastic and
rubber.
When using degreasant on plastic and rubber,
only rub with light pressure if it is necessary.
Use a soft washing sponge.
Polishing glossy trim mouldings could wear
away or damage the glossy surface layer.
Polishing agent that contains abrasive must
not be used.
IMPORTANT
Avoid washing the car with cleaning agent
with a pH value lower than 3.5 or higher than
11.5. This may result in discolouration of ano-
dised aluminium parts such as roof rack and
around the side windows.
Never use metal polishing agent on anodised
aluminium parts, this can result in discoloura-
tion and destroy the surface treatment.
Rims
Only use rim cleaning agent recommended by
Volvo.
Strong rim cleaning agents can damage the sur-
face and cause stains on chrome-plated alumi-
nium rims.
