Vehicles with spare wheel
The jack, wheel wrench, adapters (for
spare wheel removal), hub cap hook
and towing eye are contained in a
unit, stowed under the front seat.
Note
Depending on vehicle, there may be
multiple adapters for spare wheel
removal.
Vehicles with Rear-wheel drive: A hydraulic jack and a set of extension
pieces for use with the jack are also
included.

202Vehicle carefor a 10 °C temperature increase.
This must be considered when warm
tyres are checked.
Trailer towing When towing a trailer with a fullyladen vehicle, the tyre pressure must
be increased by 20 kPa/0.2 bar
(3.0 psi) and the maximum speed
limited to 100 km/h.
Trailer towing 3 172.
Rear-wheel drive, with twin rear
wheels
When inflating the outer tyre, the
inflation tube should be passed
between the two wheels.
Tyre pressure monitoringsystem
The tyre pressure monitoring system
uses radio and sensor technology to
check tyre pressure levels.Caution
Tyre pressure monitoring system
warns only about low tyre pressure condition and does not replace
regular tyre maintenance by the
driver.
All wheels must be equipped with pressure sensors and the tyres must
have the prescribed pressure.
Note
In countries where the tyre pressure
monitoring system is legally
required, the use of wheels without
pressure sensors will invalidate the
vehicle operating permit.
The tyre pressure monitoring system
sensors monitor the air pressure in
the tyres and transmit tyre pressure
readings to a receiver located in the
vehicle.
Tyre pressure chart 3 247.
Low tyre pressure condition
A detected low tyre pressure
condition is indicated by illumination
of control indicator w 3 100 and a
corresponding message appears in
the Driver Information Centre.
If w illuminates, stop as soon as
possible and inflate the tyres as
recommended 3 247.
After inflating, some driving may be
required to update the tyre pressure
values in the system. During this time
w may illuminate.
If w illuminates at lower temperatures
and extinguishes after some driving,
this could be an indicator for

Vehicle care213If your vehicle gets a flat tyre on the
rear while towing another vehicle,
mount the temporary spare wheel in
the front and the full tyre in the rear.
Tyre chains 3 205.
Summer and winter tyres If you use winter tyres, the spare
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.Jump starting
The jump start terminal is located in
the engine compartment.
A vehicle with a discharged vehicle
battery can be started using jump
leads and the vehicle battery of
another vehicle.
Do not start with a quick charger.9 Warning
Be extremely careful when starting
with jump leads. Any deviation
from the following instructions can
lead to injuries or damage caused
by battery explosion or damage to the electrical systems of both
vehicles.
9 Warning
Avoid contact of the battery with
eyes, skin, fabrics and painted
surfaces. The fluid contains
sulphuric acid which can cause
injuries and damage in the event
of direct contact.

216Vehicle careTowingTowing the vehicle
The towing eye and wheel wrench are stowed with the vehicle tools 3 199.
Disengage the cover using a suitable
tool and remove.
Screw the towing eye clockwise into
the front towing point and tighten fully using the wheel wrench.
Attach a tow rope - or better still a tow
rod - to the towing eye, never to the
bumper or front suspension units.
Caution
Do not tow the vehicle from the
rear. The front towing eye must
only be used for towing and not
recovering a vehicle.
Switch on ignition to permit operation
of brake lights, horn and windscreen
wipers, and move the steering wheel
slightly to release the steering wheel
lock.
Switch off the air suspension system 3 141.
Move the selector lever to neutral.
Release the parking brake.
Caution
Vehicles with manual
transmission automated: If neutral cannot be selected, the vehiclemust only be towed with the drive
wheels raised off the ground.
The vehicle should always be
towed with the ignition switched
off.
Manual transmission automated
3 151.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 fumes
from the towing vehicle, switch on the air recirculation system 3 118 and
close the windows.
Seek the assistance of a workshop.
After towing, unscrew the towing eye
and refit the cover.

Vehicle care217Towing another vehicle
Attach a tow rope - or better still a tow
rod - to the rear towing eye, never to
the rear axle and suspension units.
Caution
The rear towing eye must only be
used for towing and not recovering a vehicle.
Caution
Drive slowly. Do not drive jerkily.
Excessive tractive force can
damage the vehicle.
Appearance care
Exterior care Locks
The locks are lubricated at the factory using 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.
WashingThe 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. Restrictions for
filmed or matt painted body parts or
decor tapes, see "Polishing and
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.

Vehicle care219For 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.
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.
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.
Towing equipment Do not clean the coupling ball bar with
a steam-jet or high-pressure jet
cleaner.Interior care
Interior and upholstery Only clean the vehicle interior,
including the instrument panel fascia
and panelling, with a dry cloth or
interior cleaner.
Clean 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.
Clothing fabrics may not be
colourfast. This could cause visible
discolourations, especially on light- coloured upholstery. Removable
stains and discolourations should be
cleaned as soon as possible.
Clean seat belts with lukewarm water or interior cleaner.
