A detected low tyre pressure
condition is indicated by the control
indicator w 3 97.
If w illuminates, stop as soon as
possible and inflate the tyres as
recommended 3 234.
If w flashes for 60-90 seconds and
then illuminates continuously, there is
a fault in the system. Consult a
workshop.
After inflating, 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 some driving,
this could be an indicator for
approaching a low tyre pressure
condition. Check tyre pressure.
Vehicle messages 3 105.
If the tyre pressure shall 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 temporary spare wheel is not
equipped with pressure sensors. The
tyre pressure monitoring system is
not operational for these wheels.
Control indicator w illuminates. For
the further three wheels 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
clipped sensor: replace complete
valve stem.
Vehicle loading status
Adjust tyre pressure to load condition
according to tyre information label or tyre pressure chart 3 234, and select
the relevant setting in the menu Tyre
Load in the Driver Information Centre,
Vehicle Information Menu 3 100 . This
setting is the reference for the tyre
pressure warnings.
The Tyre Load menu only appears if
the vehicle is in a standstill and the
parking brake is applied. On vehicles
with automatic transmission the
selector lever has to be in P.

Select:● Light for comfort pressure up to
3 people.
● Eco for Eco pressure up to
3 people.
● Max for full loading.
Tyre pressure sensor matching
process
Each tyre pressure 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 the tyre
pressure sensor.
The malfunction light w and the
warning message or code should go
off 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 or
purchase a relearn tool. 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: select neutral.
4. Press 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.
6. Press SET/CLR to begin the
sensor matching process. A
message requesting acceptance
of the process should display.
7. Press SET/CLR again to confirm
the selection. The horn sounds
twice to signal the receiver is in
relearn mode.
8. Start with the left side front wheel.
9. Place the relearn tool against the tyre sidewall, near the valve stem.Then press the button to activate
the tyre pressure sensor. A horn
chirp and the brief activation of all turn signal lights confirm that the
