176Vehicle care
The tyre pressure tables show allpossible tyre combinations 3 206.
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.
Tyre pressure monitoring
system
The tyre pressure monitoring system
continually checks the pressure of all
four wheels when vehicle speed
exceeds a certain limit.
All wheels must be equipped with
pressure sensors and the tyres must
have the prescribed pressure.
When a low tyre condition is detected,
A illuminates. If A comes on, stop as
soon as possible and inflate the tyres as recommended in this manual. Tyre pressures 3 206.
After inflating the tyres to the
appropriate pressure, A may stay
illuminated. Pressure change will be
recognized as the vehicles is driven.
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 current tyre pressures may be
shown in the Info-Display 3 107.
Vehicle messages, tyre pressure 3 102.
Control indicator w 3 91.
If the tyre pressure shall be reduced
or increased, switch off ignition.
w may come on in cool weather when
the vehicle is first started and then
turn off as the vehicle is driven. Thiscould be an early indicator that the air
pressure is getting low and needs to
be inflated to the proper pressure.
A spare or temporary spare wheel is
not equipped with pressure sensors.
The tyre pressure monitoring system
is not operational for these wheels
and w illuminates.
Winter tyres or additional wheel sets
have to be fitted with sensors,
otherwise the system will not work
and w will indicate malfunction by
flashing one minute and then
illuminate continuously.
The use of commercially available
liquid tyre repair kits can impair the
function of the system. Factory-
approved repair kits can be used.
External high-power radio equipment
could disrupt the tyre pressure
monitoring system.
Unsuited rims can impair the
transmission quality of the tyre
pressure monitoring system sensors.
