■ One or more TPMS sensors are missing or damaged. The warning
message or code and the
malfunction light should go off
when the TPMS sensors are
installed and the sensor matching
process is performed successfully.
Consult your workshop for service.
■ Replacement tyres or wheels do not match the original equipment
tyres or wheels. Tyres and wheels other than those recommended
could prevent the TPMS from
functioning properly.
■ Operating electronic devices or being near facilities using radio
wave frequencies similar to the
TPMS could cause the TPMS
sensors to malfunction.
If the TPMS is not functioning
properly, it cannot detect or signal
a low tyre condition. Consult your
workshop for service if the TPMS
malfunction light and a warningmessage or code come on and stay
on.
TPMS Sensor Matching Process
Each TPMS sensor has a unique
identification code. The identification
code must be matched to a new tyre/ wheel position after rotating the tyres
or replacing one or more of the TPMS
sensors. The TPMS sensor matching
process should also be performed
after replacing a spare tyre with a
road tyre containing the TPMS
sensor.
The malfunction light and the warning message or code should go off at the
next ignition cycle. The sensors are
matched to the tyre/wheel positions,
using a TPMS relearn tool, in the
following order: driver side front tyre,
passenger side front tyre, passenger side rear tyre, and driver side rear.
Consult your workshop for service or
to purchase a relearn tool. There are
two minutes to match the first tyre/
wheel position, and five minutes
overall to match all four tyre/wheelpositions. If it takes longer, the
matching process stops and must be
restarted.
The TPMS sensor matching process
is:
1. Apply the parking brake.
2. Turn the ignition on.
3. Use the MENU button on the turn
signal lever to select the Vehicle
Information Menu in the Driver
Information Centre (DIC).
4. Use the thumbwheel to scroll to the tyre pressure menu.
5. Press the SET/CLR button to
begin the sensor matching
process. A message requesting
acceptance of the process should
display.
6. Press the SET/CLR button again
to confirm the selection. The horn sounds twice to signal the
receiver is in relearn mode.
7. Start with the driver side front tyre.
8. Place the relearn tool against the tyre sidewall, near the valve stem.
Then press the button to activate
the TPMS sensor. A horn chirp
Vehicle care177
confirms that the sensoridentification code has been
matched to this tyre and wheel
position.
9. Proceed to the passenger side front tyre, and repeat the
procedure in Step 8.
10. Proceed to the passenger side rear tyre, and repeat the
procedure in Step 8.
11. Proceed to the driver side rear tyre, and repeat the procedure inStep 8. The horn sounds twice to
indicate the sensor identification
code has been matched to the
driver side rear tyre, and the
TPMS sensor matching process
is no longer active.
12. Turn off the ignition.
13. Set all four tyres to the recommended air pressure level
as indicated on the tyre pressure
label.
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).
For safety reasons it is recommended
that the tread depth of the tyres on
one axle should not vary by more than 2 mm.
The legally permissible minimum
tread depth (1.6 mm) has been
reached when the tread has worn
down as far as one of the tread wear
indicators (TWI). Their position is
indicated by markings on the
sidewall.
If there is more wear at the front than
the rear, swap round front wheels and rear wheels. Ensure that the direction
of rotation of the wheels is the same
as before.
Tyres age, even if they are not used.
We recommend tyre replacement
every 6 years.
Changing tyre and wheel
size
If tyres of a different size than those
fitted at the factory are used, it may be necessary to reprogramme the
speedometer as well as the nominal tyre pressure and make other vehicle modifications.
After converting to a different tyre
size, have the label with tyre
pressures replaced.9 Warning
Use of unsuitable tyres or wheels
may lead to accidents and will
invalidate the vehicle type
approval.
