Tyre repair kit 3 154.
Spare wheel 3 159.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.
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 should
therefore be fitted on all wheels.
152Vehicle care
In accordance with country-specific
regulations, a notice indicating the
maximum permissible speed for the
tyres must be affixed within the
driver's field of vision.
Tyre designationsE.g. 215/65 R 16 C 109 R215=Tyre width, mm65=Cross-section ratio (tyre
height to tyre width), %R=Belt type:RadialRF=Type:RunFlat16=Wheel diameter, inchesC=Cargo or commercial use88=Load index e.g. 109 is

Speed code letter:
Q=up to 100 mphS=up to 112 mphT=up to 118 mphH=up to 130 mphV=up to 150 mphW=up to 168 mphTyre pressure
Check the pressure of cold tyres at least every 14 days and before any
long journey. Do not forget the spare
wheel.
Tyre pressures 3 189.
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.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.
Rear-wheel drive, with twin rear
wheels When inflating the outer tyre, the
inflation tube should be passed
between the two wheels.
Tread depth
Check 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.
Vehicle care153
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.
If there is more wear at the front than
the rear, swap round front wheels and rear wheels periodically. Ensure that
the direction of rotation of the wheels
is the same as before.
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.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.
Tyre chains
Tyre chains are only permitted on the
drive wheels.
On vehicles with twin rear wheels,
tyre chains are only permitted on the
outer wheels.
154Vehicle care
Always use fine mesh chains that addno more than 15 mm to the tyre tread
and the inboard sides (including chain
lock).9 Warning
Damage may lead to tyre blowout.
Wheel covers on steel wheels may
come into contact with parts of the
chains. In such cases, remove the
wheel covers.
Tyre chains may only be used at
speeds up to 30 mph and, when
travelling on roads that are free of
snow, they may only be used for brief
periods since they are subject to rapid wear on a hard road and may snap.
The use of tyre chains is not permitted on the temporary spare wheel.
Tyre repair kit
Minor damage to the tyre tread can be
repaired with the tyre repair kit.
Do not remove foreign bodies from
the tyres.
Tyre damage exceeding 4 mm or that
is at the tyre's sidewall near the rim
cannot be repaired with the tyre repair kit.9 Warning
Do not drive faster than 50 mph.
Do not use for a lengthy period.
Steering and handling may be
affected.
If the vehicle has a flat tyre:
Apply the parking brake and engage
first gear or reverse gear.
The tyre repair kit is located under the
front seat. Slide seat forwards fully
and fold backrest down to access kit.
1. Take the tyre repair kit out from under the front seat.
2. Remove the compressor.
3. Remove the power supply lead and air hose from the stowage
compartments on the underside
of the compressor.4. Screw the compressor air hose to
the connection on the sealant
bottle.
5. Fit the sealant bottle into the retainer on the compressor.
Set the compressor near the tyre
in such a way that the sealant
bottle is upright.
6. Unscrew valve cap from defective
tyre.
Vehicle care157
not be driven. Seek theassistance of a workshop.
20. Stow tyre repair kit under the front
seat.
Notice
The driving characteristics of the repaired tyre are severely affected, therefore have this tyre replaced.
If unusual noise is heard or the
compressor becomes hot, turn
compressor off for at least
30 minutes.
The built-in safety valve opens at a
pressure of 7 bar (102 psi).
Note the expiry date of the kit. After
this date its sealing capability is no
longer guaranteed. Pay attention to
storage information on sealant
bottle.
Replace the used sealant bottle. Dispose of the bottle as prescribed
by applicable laws.
The compressor and sealant can be used from approx. -30 °C.
The adapters supplied can be used
to pump up other items e.g.
footballs, air mattresses, inflatabledinghies etc. They are located on the underside of the compressor. To
remove, screw on compressor air hose and withdraw adapter.
Wheel changing Some vehicles are equipped with a
tyre repair kit instead of a spare wheel 3 154.
Make the following preparations and
observe the following information:
■ Park the vehicle on a level, firm and
non-slippery surface. The frontwheels must be in the straight-ahead position.
■ Apply the parking brake and engage first gear or reverse gear.
■ Switch off the air suspension system 3 110.
■ Remove the spare wheel 3 159.
■ Never change more than one wheel
at a time.
