When the system detects a
malfunction, w will flash for approx.
one minute and then remain
continuously illuminated. This
sequence will continue upon
subsequent vehicle start-ups as long
as the malfunction exists.
When w is illuminated, the system
may not be able to detect or signal low tyre pressure as intended.
Tyre Pressure Monitoring Operation
The TPMS is designed to warn the
driver when a low tyre pressure
condition exists. TPMS sensors are
mounted onto each tyre and wheel
assembly, excluding the spare tyre
and wheel assembly. The TPMS
sensors monitor the air pressure in
the tyres and transmit the tyre
pressure readings to a receiver
located in the vehicle.
When a low tyre pressure condition is
detected, w illuminates. Stop as soon
as possible and inflate the tyres to the
recommended tyre pressure 3 173.
Additionally a warning message or a
warning code is displayed in the
Driver Information Centre 3 94.
The low tyre pressure control indicator and a warning message or
code come on at each ignition cycle
until the tyres are inflated to the
correct tyre pressure.
TPMS Malfunction Indicator and
Message Code The TPMS will not function properly if
one or more of the TPMS sensors are
missing or inoperable. When the
system detects a malfunction, w
flashes for approx. one minute and then illuminates. Additionally a
warning message or code is
displayed.
The indication by the TPMS
malfunction indicator and a warning
message or code will come on at each ignition cycle until the problem iscorrected. Some of the conditions
that can cause these to come on are:
■ One of the tyres has been replaced
with the spare tyre which does not
have a TPMS sensor.
■ The TPMS sensor matching process was not done or not
completed successfully after
rotating the tyres. The malfunction
light and the warning message or
code should go off after
successfully completing the sensor

matching process. See "TPMSSensor Matching Process" later in
this section.
■ 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

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.
Page 180 of 217

178Vehicle careWheel coversWheel covers and tyres that are
factory-approved for the respective
vehicle and comply with all of the
relevant wheel and tyre combination
requirements must be used.
If the wheel covers and tyres used are
not factory-approved, the tyres must
not have a rim protection ridge.
Wheel covers must not impair brake
cooling.9 Warning
Use of unsuitable tyres or wheel
covers could lead to sudden
pressure loss and thereby
accidents.
Vehicles with alloy wheels: When
mounting steel wheels with alloy
wheel nuts, e.g. when changing to
winter tyres, the wheel covers cannot
be attached to the steel wheels.
Tyre chains
Use tyre chains only on front wheels.
9 Warning
Damage may lead to tyre blowout.
Tyre chains are permitted on tyres of
size 195/70 R16.
Always use fine mesh chains suitable
for sport utility vehicles that add no
more than 12 mm to the tyre tread and the inboard sides (including chain
lock).
On tyres of size 215/55 R18, special
snow chains are only permitted when
they are designed with a rotating
chain belt on the tyre tread, no chain
links on the wheel inboard sides and
the chains add no more than 12 mm
to the tyre tread. For further
information of right snow chain usage
for this tyre size, contact a specialized vehicle parts dealer or snow chain
manufacturer.
Tyre chains are not permitted on tyres of size 205/70 R16, 215/65 R16 and
215/60 R17.
The use of tyre chains is not permitted on the temporary spare wheel.
Tyre repair kit Minor damage to the tyre tread can be
repaired with the tyre repair kit.
Do not remove foreign bodies from
the tyres.
Tyre damage exceeding 4 mm or that
is at tyre's sidewall cannot be repaired with the tyre repair kit.

tyre.
7. Screw the filler hose to the tyre valve.
8. The switch on the compressor must be set to J.
9. Connect the compressor plug to the power outlet or cigarette
lighter socket.
To avoid discharging the battery,
we recommend running the
engine.10. Set the rocker switch on the compressor to I. The tyre is filled
with sealant.
11. The compressor pressure gauge briefly indicates up to 6 bar whilstthe sealant bottle is emptying
(approx. 30 seconds). Then the
pressure starts to drop.
12. All of the sealant is pumped into the tyre. Then the tyre is inflated.
13. The prescribed tyre pressure should be obtained within
10 minutes. Tyre pressure
3 206 . When the correct pressure
is obtained, switch off the compressor.If the prescribed tyre pressure is
not obtained within 10 minutes,
remove the tyre repair kit. Move
the vehicle one tyre rotation.
Reattach the tyre repair kit and
continue the filling procedure for
10 minutes. If the prescribed tyre pressure is still not obtained, the
tyre is too badly damaged. Seek
the assistance of a workshop.
Drain excess tyre pressure with
the button over the pressure
indicator.
Do not run the compressor longer than 10 minutes.

14. Detach the tyre repair kit. Pushcatch on bracket to remove
sealant bottle from bracket. Screw
the tyre inflation hose to the free
connection of the sealant bottle.
This prevents sealant from
escaping. Stow tyre repair kit in
load compartment.
15. Remove any excess sealant using a cloth.
16. Take the label indicating maximum permitted speed from
the sealant bottle and affix in the
driver's field of view.
17. Continue driving immediately so that sealant is evenly distributedin the tyre. After driving approx.
10 km (but no more than 10 minutes), stop and check tyre
pressure. Screw compressor air
hose directly onto tyre valve and
compressor when doing this.
If tyre pressure is more than
1.3 bar , set it to the correct value.
Repeat the procedure until there
is no more loss of pressure.
If the tyre pressure has fallen
below 1.3 bar, the vehicle must
not be used. Seek the assistance
of a workshop.
18. Stow away tyre repair kit in load compartment.
Note
The driving characteristics of the
repaired tyre are severely affected,
therefore have this tyre replaced.
If unusual noise is heard or the
compressor becomes hot, turn
compressor off for at least
30 minutes.
The built-in safety valve opens at a
pressure of 7 bar.
Note the expiry date of the kit. After
this date its sealing capability is no
longer guaranteed. Pay attention to
storage information on sealant
bottle.
Replace the used sealant bottle. Dispose of the bottle as prescribed
by applicable laws.
The compressor and sealant can be
used from approx. -30 °C.
The adapters supplied can be used
to pump up other items e.g.
footballs, air mattresses, inflatable
dinghies etc. They are located on the underside of the compressor. To
remove, screw on compressor air hose and withdraw adapter.
