182Vehicle care10 °C temperature increase. This
must be considered when warm tyres are checked.
Rear-wheel drive, with twin rear
wheels
When inflating the outer tyre, the
inflation tube should be passed
between the two wheels.
Tyre 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 3 225.
Low tyre pressure conditionA detected low tyre pressure
condition is indicated by illumination
of control indicator w 3 89 and a
corresponding message appears in
the DIC.
If w illuminates, stop as soon as
possible and inflate the tyres as
recommended 3 225.
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 A 3 87 and a
corresponding message appears in
the DIC.

Vehicle care183A 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.

Puncture A puncture or severely under-inflated
tyre is indicated by illumination of
control indicator w together with C
3 88 and a corresponding message
appears in the DIC. Stop vehicle and
switch off engine.

3 185, Spare wheel 3 190, Wheel
changing 3 188.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 3 225, Tyre repair kit
3 185.
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 92.
Vehicle messages 3 92.
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 3 185, Tyre chains
3 185.
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.
