Spare wheel 3 190.Wheels and tyres
Tyre condition, wheel condition Drive over edges slowly and at right
angles if possible. Driving over sharp
edges can cause tyre and wheel
damage. Do not trap tyres on the kerb
when parking.
Regularly check the wheels for
damage. Seek the assistance of a
workshop in the event of damage or
unusual wear.
We recommend not swapping the
front wheels with the rear wheels and vice versa, as this can affect vehiclestability. Always use less worn tyres
on the rear axle.
Tyres
Factory-fitted tyres are matched to the chassis and offer optimum driving comfort and safety.Winter tyres
Winter tyres improve driving safety at temperatures below 7 °C and shouldtherefore be fitted on all wheels.
In accordance with country-specific
regulations, affix the maximum speed
sticker in the driver's field of view.

Vehicle care181Choose a tyre appropriate for the
maximum speed of your vehicle.
The maximum speed is achievable at
kerb weight with driver (75 kg) plus
125 kg payload. Optional equipment
could reduce the maximum speed of
the vehicle.
Directional tyres Fit directional tyres such that they rollin the direction of travel. The rolling
direction is indicated by a symbol
(e.g. an arrow) on the sidewall.
Tyre pressure
Check the pressure of cold tyres at
least every 14 days and before any
long journey. Do not forget the spare
wheel. This also applies to vehicles
with tyre pressure monitoring system.
The tyre pressure information label
on the driver's door frame indicates
the original equipment tyres and the
correspondent tyre pressures.
Always inflate tyres to the pressures
shown on the label.
Tyre pressures 3 225.The tyre pressure data refers to cold
tyres. It applies to summer and winter tyres.
Always inflate the spare tyre to the
pressure specified for full load.
Incorrect tyre pressures will impair
safety, vehicle handling, comfort and
fuel economy and will increase tyre
wear.
Tyre pressures differ depending on
various options. For the correct tyre
pressure value, follow the procedure
below:
1. Identify the engine identifier code.
Engine data 3 206.
2. Identify the respective tyre.
The tyre pressure tables show all
possible tyre combinations 3 225.
For the tyres approved for your
vehicle, refer to the EEC Certificate of Conformity provided with your vehicle
or other national registration
documents.
The driver is responsible for correct
adjustment of tyre pressure.9 Warning
If the pressure is too low, this can
result in considerable tyre warm-
up and internal damage, leading to tread separation and even to tyre
blow-out at high speeds.
9 Warning
For specific tyres the
recommended tyre pressure as
shown in the tyre pressure table may exceed the maximum tyre
pressure as indicated on the tyre.
Never exceed the maximum tyre
pressure as indicated on the tyre.
Temperature dependency
Tyre pressure depends on the
temperature of the tyre. During
driving, tyre temperature and
pressure increase.
Tyre pressure values provided on the
tyre information label and tyre
pressure chart are valid for cold tyres, which means at 20 °C. The pressure
increases by nearly 1.5 psi for a
184Vehicle careTread depthCheck tread depth at regular
intervals.
Tyres should be replaced for safety
reasons at a tread depth of 2-3 mm
(4 mm for winter tyres).
For safety reasons it is recommended
that the tread depth of the tyres on
one axle should not vary by more than 2 mm.
The legally permissible minimum
tread depth (1.6 mm) has been
reached when the tread has worn
down as far as one of the tread wear
indicators (TWI). Their position is
indicated by markings on the
sidewall.
Tyres age, even if they are not used.
We recommend tyre replacement
every 6 years.
Changing tyre and wheel size
If tyres of a different size than those fitted at the factory are used, it may be necessary to reprogramme the
speedometer as well as the nominal
tyre pressure and make other vehicle modifications.
After converting to a different tyre
size, have the label with tyre
pressures replaced.9 Warning
Use of unsuitable tyres or wheels
may lead to accidents and will
invalidate the vehicle type
approval.
Wheel covers
Wheel covers and tyres that are
factory approved for the respective
vehicle and comply with all of the
relevant wheel and tyre combination requirements must be used.
If the wheel covers and tyres used are
not factory approved, the tyres must
not have a rim protection ridge.
Wheel covers must not impair brake
cooling.9 Warning
Use of unsuitable tyres or wheel
covers could lead to sudden
pressure loss and thereby
accidents.
190Vehicle careEnsure the jack is positioned
correctly. The jack head must be
level with the jacking hole. Pump
the jack by pressing the wheel
wrench, to position the base plate
correctly.
Raise the vehicle by pressing the
wheel wrench until the wheel is
clear of the ground.
4. Unscrew wheel bolts/nuts completely and wipe clean with a
cloth.
Put wheel bolts/nuts somewhere
where the threads will not be
soiled.
5. Change the wheel.
6. Screw in the wheel bolts/nuts.
7. Lower vehicle.
8. Install the wheel wrench ensuring that it locates securely and tighten
each wheel bolt/nut in a crosswise sequence. Tightening torque is:
172 Nm (Front-wheel drive),
235 Nm (Rear-wheel drive with
twin rear wheels), 264 Nm (Rear-
wheel drive with single rear
wheels).9. Refit wheel cover.
Notice
If applicable, fit anti-theft bolts
nearest the tyre valve (otherwise it
may not be possible to refit the wheel cover).
10. Stow the replaced wheel 3 190
and the vehicle tools 3 179.
11. Have the new wheel balanced on the vehicle. Check the tyre
pressure of the installed tyre
3 225 and also the wheel bolt/nut
torque as soon as possible.
Have the defective tyre renewed or
repaired.
Spare wheel Some vehicles are equipped with a
tyre repair kit instead of a spare wheel
3 185.
If mounting a spare wheel which is
different from the other wheels, this
wheel might be classified as a
temporary spare wheel and the
corresponding speed limits apply,
even though no label indicates this.
Seek the assistance of a workshop to
check the applicable speed limit.Caution
The use of a spare wheel that is smaller than the other wheels or in combination with winter tyres
could affect driveability. Have the defective tyre replaced as soon as
possible.
The spare wheel is held under the
vehicle frame using a winch and
secured by tightening a cable using
the wheel wrench and adapters
(depending on vehicle).
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.
192Vehicle care
Place wheel below the vehicle frame,
directly beneath the winch
mechanism.
Then tighten cable using the wheel
wrench and adapters by connecting
to the slot position illustrated above
and turning wrench anticlockwise
until the wheel is secured in the fully
raised position.9 Warning
Ensure the front of the wheel (side
with tyre valve) is facing upwards
when the spare wheel is
reinstalled below the vehicle
frame.
Temporary spare wheel
Caution
The use of a spare wheel that is smaller than the other wheels or in combination with winter tyres
could affect driveability. Have the defective tyre replaced as soon as
possible.
Only mount one temporary spare
wheel. Do not drive faster than
50 mph. Take curves slowly. Do not
use for a long period of time.
If 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 3 185.
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 rollin 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.
198Vehicle careUnpainted plastic body parts must notbe treated with wax or polishing
agents.
Matt filmed body parts or decor tapes must not be polished, to avoid
gleaming. Do not use hot wax
programmes in automatic car washes if the vehicle is equipped with theseparts.
Matt painted decor parts, e.g. mirror
housing cover, must not be polished.
Otherwise these parts would become
agleam or the colour would be
dissolved.
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.
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.
