to case and stow under the driver's seat.17. Continue driving immediately so that the sealant is evenlydistributed throughout the tyre.
After driving approx. ten km, but
no more than ten minutes, stop
and check tyre pressure using the
compressor. Screw air hose from
compressor directly onto tyre
valve when doing this.
18. If the tyre pressure is more than 2.2 bar (220 kPa/31 psi), set it to
the correct value. Repeat the
procedure until there is no more
loss of pressure.
If the tyre pressure has fallen
below 2.2 bar (220 kPa/31 psi),
the vehicle must not be driven.
Seek the assistance of a
workshop.
19. Detach the tyre repair kit, return to

Wheel changing
Some vehicles are equipped with a
tyre repair kit instead of a spare wheel
3 189.
Make the following preparations and
observe the following information:
● Park the vehicle on a level, firm and non-slippery surface. The
front wheels must be in the
straight-ahead position.
● Apply the parking brake and engage first gear or reverse gear.● Remove the spare wheel 3 193.
● Never change more than one wheel at a time.
● Use the jack only to change wheels in case of puncture, not
for a 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.
● Remove 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 engine when the vehicle is raised on the jack.
● Clean wheel bolts/nuts and thread with a clean cloth before
mounting the wheel.9 Warning

Page 196 of 233

194Vehicle careCaution
The use of a spare wheel that issmaller than the other wheels or in combination with winter tyres
could affect driveability. Have the defective tyre replaced as soon as
possible.
It may be necessary to jack the
vehicle up to gain access to the spare
wheel on a fully loaded vehicle with a
flat rear tyre.
Wheel changing 3 192.
The spare wheel is mounted under
the rear underbody and may be
secured using a security bolt that can
only be removed using the wheel bolt sleeve supplied. Vehicle tools 3 183.9 Warning
Due to the weight of the tyre
assembly, exercise caution when
releasing the spare wheel carrier.

wheel may still be fitted with a
summer tyre.
If you use the spare wheel when it is
fitted with a summer tyre the vehicle's driveability may be affected,
especially on slippery road surfaces.
Directional tyres
Fit directional tyres such that they roll in the direction of travel. The rolling
direction is indicated by a symbol
(e.g. an arrow) on the sidewall.
The following applies to tyres fitted
opposing the rolling direction:
● Driveability may be affected. Have the defective tyre renewed
or repaired as soon as possible
and fit it instead of the spare
wheel.
● Do not drive faster than 80 km/h.
● Drive particularly carefully on wet
and snow-covered road
surfaces.

Appearance care
Exterior 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 adegreasing effect and impairs lockfunction. After using a de-icing agent,
have the locks regreased by a
workshop.
Washing
The paintwork of your vehicle is
exposed to environmental influences, therefore wash your vehicle regularly.
When using automatic vehicle
washes, we recommend one with
textile brushes and a programme
without wax additives. Restrictions for
filmed or matt painted body parts or
decor tapes, see "Polishing and
waxing".
Never use a steam-jet or high-
pressure jet cleaner for the engine
compartment.Wax painted parts of the vehicle
regularly.
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 wipers
and rear window wiper must be
switched off and the exterior mirrors
must be folded in. 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 damage.
