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matching process is no longer
active.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.
