164Vehicle careWheels 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 vehicle
stability. 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 should
therefore be fitted on all wheels.
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 designations
E.g. 195/65 R 16 C 88 Q195: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. 88 is
equivalent to 567 kgQ:Speed code letter
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 mph
Choose 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 roll in 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.

166Vehicle careTyre pressure monitoring
system
The Tyre Pressure Monitoring
System (TPMS) 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.
Notice
In countries where the tyre pressure
monitoring system is legally
required, the use of wheels without
pressure sensors will invalidate the
vehicle type approval.
The TPMS sensors monitor the air
pressure in the tyres and transmit tyre pressure readings to a receiver
located in the vehicle.
Tyre pressure chart 3 198.
Low tyre pressure condition
A detected low tyre pressure
condition is indicated by illumination
of control indicator w 3 88 and a
corresponding message appears in
the DIC.
If w illuminates, stop as soon as
possible and inflate the tyres as
recommended 3 198.
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
approaching a low tyre pressure
condition. Check tyre pressure of all
four tyres.
If the tyre pressure must be reduced
or increased, switch off ignition.
Only mount wheels with pressure
sensors, otherwise w flashes for
several seconds then illuminates
continuously together with control
indicator F 3 86 and a corresponding
message appears in the DIC.
A spare wheel or temporary spare
wheel is not equipped with pressure
sensors. TPMS is not operational for
these wheels. For the further three
wheels, TPMS remains operational.
Control indicator w and the
corresponding message appears at
each ignition cycle until the tyres are
inflated to the correct tyre pressure.

Vehicle messages 3 91.

Vehicle care167PunctureA puncture or severely under-inflated
tyre is indicated by illumination of
control indicator w together with C
3 86 and a corresponding message
appears in the DIC. Stop vehicle and
switch off engine.

3 169, Spare wheel 3 173, Wheel

Relearn function
After a puncture has been repaired
and the driver has inflated the tyres to
the correct tyre pressure, TPMS
needs to recalculate.
Tyre pressure 3 198, Tyre repair kit
3 169.
During driving, select the tyre
pressure menu in the DIC by pressing button on end of wiper lever. Press
and hold button for approx.
5 seconds to initialise recalculation. A
corresponding message appears in
the DIC.
Several minutes of driving at a speed above 25 mph may be required tocomplete the relearn process. The
system can only provide limited
information during this time.
If problems occur during the relearn
process, control indicator w remains
illuminated and a warning message is
displayed in the DIC.
Driver Information Centre (DIC) 3 90.
Vehicle messages 3 91.
General information The use of tyre chains or
commercially available liquid tyre
repair kits can impair the function of
the system. Factory-approved tyre
repair kits can be used.Tyre repair kit 3 169, Tyre chains
3 168.
External high-power radio equipment
could disrupt the tyre pressure
monitoring system.
Each time the tyres are replaced,
TPMS sensors must be dismounted
and serviced by a workshop.
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 care169For tyre size 215/60 R17, consult a
workshop.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 or
sidewall 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 tyre 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
driver's seat. Vehicle tools 3 163.
1. Remove the compressor and sealant bottle from the tyre repairkit case.
2. Remove the electrical connection cable and air hose from the
compartments on the underside
of the compressor.3. Screw the air hose to the connection on the sealant bottle.
4. 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.
5. Unscrew valve cap from defective
tyre.

Vehicle care171Drain excess tyre pressure with
the button beside the pressure
indicator.
Do not run the compressor for
longer than 15 minutes.
13. Detach the tyre repair kit.
14. Remove any excess sealant using a cloth.
15. Take the label indicating maximum permitted speed from
the tyre repair kit and affix in the driver's field of view.
16. Store the sealant bottle in the plastic bag. Return tyre repair kit
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. 6 miles, but
no more than 10 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
case and stow under the driver's
seat.9 Warning
Do not allow the sealant to contact
skin, eyes or clothing. If swallowed seek medical assistance
immediately.
Notice
The driving characteristics of the
repaired tyre is 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.
Pay attention to storage information
and expiry date on sealant bottle. Its
sealing capability is not guaranteed
after this time.
Replace the used sealant bottle.
Dispose of the sealant bottle as
prescribed by applicable laws.
Wheel changing
Some vehicles are equipped with a
tyre repair kit instead of a spare wheel
3 169.
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.
