Vehicle care217After inflating, some driving may be
required to update the tyre pressure
values in the Driver Information
Centre. During this time w may
illuminate.
If w illuminates at lower temperatures
and extinguishes after driving, this
could be an indicator for approaching
a low tyre pressure condition. Check
tyre pressure.
Vehicle messages 3 104.
If the tyre pressure must be reduced
or increased, switch off ignition.
Only mount wheels with pressure
sensors, otherwise the tyre pressure
will not be displayed and w
illuminates continuously.
A spare wheel or temporary spare
wheel is not equipped with pressure
sensors. The tyre pressure
monitoring system is not operational
for these tyres. Control indicator w
illuminates. For the further three
tyres, the system remains
operational.The use of commercially-available
liquid tyre repair kits can impair the
function of the system. Factory-
approved repair kits can be used.
Operating electronic devices or being close to facilities using similar wave
frequencies could disrupt the tyre
pressure monitoring system.
Each time the tyres are replaced, tyre pressure monitoring system sensors
must be dismounted and serviced.
For the screwed sensor; replace
valve core and sealing ring. For the
clipped sensor; replace complete
valve stem.
Vehicle loading status Adjust tyre pressure to load condition
according to the tyre information label or tyre pressure chart 3 255, and
select the appropriate setting in the menu Tyre Load in the Driver
Information Centre, Vehicle
Information Menu 3 98 . This setting is
the reference for the tyre pressure
warnings.The menu Tyre Load only appears
when the vehicle is at a standstill and the parking brake is applied. On
vehicles with automatic transmission,
the selector lever must be in P.

Tyre pressure sensor matching
process
Each TPMS sensor has a unique
identification code. The identification
code must be matched to a new
wheel position after rotating the
wheels or exchanging the complete
wheel set and if one or more tyre
pressure sensors were replaced. The
tyre pressure sensor matching
process should also be performed
after replacing a spare wheel with a
road wheel containing a tyre pressure
sensor.
The malfunction light w and the
warning message or code should
extinguish at the next ignition cycle. The sensors are matched to the
wheel positions, using a relearn tool,
in the following order: left side front
wheel, right side front wheel, right
side rear wheel and left side rear
wheel. The turn signal light at the
current active position is illuminated
until sensor is matched.
Consult a workshop for service. There are two minutes to match the first
wheel position, and five minutes
overall to match all four wheel
positions. If it takes longer, the
matching process stops and must be
restarted.
The tyre pressure sensor matching
process is:
1. Apply the parking brake.
2. Turn the ignition on.3. On vehicles with automatic transmission: set the selector
lever to P.
On vehicles with manual
transmission automated: Keep
brake pedal depressed. Move and hold the selector lever for five
seconds to position N until P is
displayed in the Driver Information Centre. P indicates
that the tyre pressure sensor
matching process can be started.
On vehicles with manual
transmission: select neutral.
4. Use MENU on the turn signal
lever to select the Vehicle
Information Menu ? in the
Driver Information Centre.
5. Turn the adjuster wheel to scroll to
the tyre pressure menu.
