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.

Vehicle care177
Each time the tyres are replaced, the
tyre pressure monitoring system
sensors have to be dismounted and
serviced. For the screwed sensor
replace the valve core and sealing
ring, for the clipped sensor replace
complete rubber valve stem.
Auto learn function After changing wheels the vehicle
must be stationary for approx.
20 minutes, before the system
recalculates. The following relearn
process takes up to 10 minutes of
driving with a minimum speed of
25 km/h. ---- can be displayed in the
Info-display or pressure values can
swap.
If problems occur during the relearn
process, w will flash and then
illuminate continously.Temperature dependency
Cold tyres decrease the tyre
pressure, warm tyres increase the
tyre pressure. During driving tyre
temperature and pressure increase.
The displayed tyre pressure value
shows the actual tyre pressure.
Therefore it is important to check tyre
pressure with cold tyres.
System initialisation
After a wheel change or tyre pressure
adjustment, the system must be
initialised: inflate the cold tyres to the
prescribed pressure according to the
tyre information label or this
document 3 206. Then switch on
ignition and press and hold the DDS
button for approx. 4 seconds. w
flashes three times.
If the tyre pressure difference
between the left and the right wheel
on one axle is more than 30 kPa, tyre
pressure monitoring system
malfunction will be indicated, as the vehicle starts moving for the first time after initialisation. Adjust the tyre
pressure and repeat initialisation.
Notice
The system needs to be initialised
after tyre pressure change,
otherwise it will not be able to warn
properly.
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).
