After having changed defective fuses,
close the fuse box cover and press
until it engages.
If the fuse box cover is not closed
correctly, malfunction may occur.
Instrument panel fuse box
In left-hand drive vehicles, the fuse
box is behind the storage
compartment in the instrument panel.
Open the compartment and push it to the left to unlock. Fold the
compartment down and remove it.
280Vehicle careTowingTowing 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 3 259.
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.
Caution
Drive slowly. Do not drive jerkily.
Excessive tractive force can
damage the vehicle.
When the engine is not running,
considerably more force is needed to
brake and steer.
To prevent the entry of exhaust gases from the towing vehicle, switch on the
air recirculation and close the
windows.
Vehicles with automatic transmission: The vehicle must be towed facing
forwards, not faster than 50 mph nor further than 60 miles. In all other
cases and when the transmission is
defective, the front axle must be
raised off the ground.
Seek the assistance of a workshop. After towing, unscrew the towing eye.
Insert cap at the top and engage
downwards.
282Vehicle careAppearance careExterior care
Locks The locks are lubricated at the factoryusing a high quality lock cylinder
grease. Use de-icing agent only when
absolutely necessary, as this has a
degreasing effect and impairs lock function. After using a de-icing agent, have the locks regreased by a
workshop.
Washing The paintwork of your vehicle is
exposed to environmental influences. Wash and wax your vehicle regularly.
When using automatic vehicle
washes, select a programme that
includes waxing.
Bird droppings, dead insects, resin,
pollen and the like should be cleaned
off immediately, as they contain
aggressive constituents which can
cause paint damage.If using a vehicle wash, comply with
the vehicle wash manufacturer's
instructions. The windscreen wiper and rear window wiper must be
switched off. Remove antenna and
external accessories such as roof
racks etc.
If you wash your vehicle by hand,
make sure that the insides of the
wheel housings are also thoroughly
rinsed out.
Clean edges and folds on opened
doors and the bonnet as well as the
areas they cover.
Clean bright metal mouldings with a
cleaning solution approved for
aluminium to avoid damages.Caution
Always use a cleaning agent with
a pH value of four to nine.
Do not use cleaning agents on hot surfaces.
Have the door hinges of all doors
greased by a workshop.
Do not clean the engine compartment with a steam-jet or high-pressure jet
cleaner.
On vehicles with emblem touchpad:
when cleaning with a high-pressure
jet cleaner ensure a minimum
distance of 30 cm when working
around the tailgate to prevent
unintended unlocking.
Thoroughly 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.
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.
Vehicle care283Polishing 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 cleanerand 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.
Glass panel 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 glass panel.
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 damage Rectify 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.
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.
