Vehicle care213If 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 3 101.
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
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 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 the tyre information label or tyre pressure chart 3 247, and
select the appropriate setting in the Tyre load menu in the Driver
Information Centre 3 95. This setting
is the reference for the tyre pressure
warnings.
The menu Tyre Load only appears if
the vehicle is at a standstill and the
parking brake is applied. On vehicles
with automatic transmission, the
selector lever must 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.
214Vehicle careThe tyre pressure sensor matchingprocess 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 the sensor is matched.
Consult your 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 as follows:
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. 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.
6. Press SET/CLR to begin the
sensor matching process. A
message requesting acceptance
of the process should be
displayed.
7. Press SET/CLR again to confirm
the selection. The horn sounds
twice to indicate that 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 activatethe tyre pressure sensor. A horn
chirp confirms that the sensor
identification code has been
matched to this wheel position.10. Proceed to the right side front wheel, and repeat the procedure
in Step 9.
11. Proceed to the right side rear wheel, and repeat the procedure
in Step 9.
12. Proceed to the left side rear wheel, and repeat the procedure
in Step 9. The horn sounds twice
to indicate the sensor
identification code has been
matched to the left side rear tyre,
and the tyre pressure sensor
matching process is no longer
active.
13. Turn off the ignition.
14. Set all four tyres to the recommended tyre pressure as
indicated on the tyre pressure
information label.
15. Ensure the tyre loading status is set according to the selected
pressure 3 95.
228Vehicle care4. Switch on electrical consumers(e.g. headlights, heated rear
window) of the vehicle receiving
the jump start.
5. Reverse above sequence exactly when removing leads.Towing
Towing the vehicle
Insert a screwdriver in the slot at the
lower part of the cap. Release the cap
by carefully moving the screwdriver
downwards.
The towing eye is stowed with the
vehicle tools 3 210.
Screw in the towing eye anticlockwise
as far as it will go until it stops in a
horizontal position.
Attach a tow rope – or better still a tow rod – to the towing eye.
The towing eye must only be used for
towing and not for recovering the
vehicle.
Switch on ignition to release steering
wheel lock and to permit operation of
brake lights, horn and windscreen
wiper.
Transmission in neutral.
