Notice
In countries where the tyre pressure
monitoring system is legally
required, the use of wheels without
pressure sensors will invalidate the
vehicle type approval.
The TPMS sensors monitor the air
pressure in the tyres and transmit tyre pressure readings to a receiver
located in the vehicle.
Each tyre, including the spare, should be checked monthly when cold and
inflated to the recommended inflation
pressure 3 210.
Low tyre pressure conditionA detected low tyre pressure
condition is indicated by control
indicator w 3 89.
If w illuminates, stop as soon as
possible and inflate the tyres as
recommended 3 210.
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 pressures in Info-Display
The current tyre pressures can be
shown in the menu item Tyres in the
Board Computer menu. Press the
BC button on the Infotainment system
and select the menu item.
The tyre pressure monitoring system
automatically detects the vehicle
load. A corresponding message may appear on the Info-Display if
inconsistent tyre pressures are
detected. In some versions, the
message is displayed in abbreviated
form.

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 a TPMS sensor. The
control indicator w and the warning
message should extinguish at the
next ignition cycle.
The sensors are matched to the tyre/
wheel positions, using a TPMS
relearn tool, in the following order:
■ left front tyre
■ right front tyre
■ right rear tyre
■ left rear tyre
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 fourtyre/wheel positions. If it takes longer,
the matching process stops and must be restarted.
The TPMS sensor matching process
is as follows:
1. Apply the electrical parking brake 3 137 ; on vehicles with automatic
transmission move the selector
lever to position P.
2. Turn the ignition on 3 124.
3. Initiate the TPMS Learn Mode by simultaneously pressing buttons
p and q on the radio remote
control,
- or -
Press the INFO button on the
Infotainment system until a tyre
learn message appears on the
Info-display. Press and hold the
OK button.
The horn sounds twice and the left front turn signal also illuminates
as confirmation that Learn Mode
has been enabled.
4. Start with the left front tyre.5. Place the relearn tool against the tyre sidewall, near the valve stem.Then press the button to activatethe TPMS sensor. A horn chirp
confirms that the sensor
identification code has been
matched to this tyre and wheel
position. The next relevant turn
signal illuminates.
6. Proceed to the right front tyre, and
repeat the procedure in Step 5.
7. Proceed to the right rear tyre, and
repeat the procedure in Step 5.
8. Proceed to the left rear tyre, and repeat the procedure in Step 5.
The horn sounds twice to indicate
the sensor identification code has been matched, and the TPMS
sensor matching process is no
longer active.
9. Turn off the ignition.
10. Set all four tyres to the recommended inflation pressure
3 210.

Do not allow objects to protrude
above the top of the rear floor
storage compartment, to avoid
damage to the storage area and
the load compartment floor.
1. Release the sealant filler hose 1
and the power plug 2.
2. Unscrew valve cap from defective
tyre.
Screw the sealant filler hose onto
the tyre valve.
3. Connect the power plug to the power outlet. Unplug all items
from other power outlets.
4. Switch on ignition. To avoid discharging the battery, werecommend running the engine.
5. Turn the selector switch anticlockwise to the sealant +
air position.
6. Press the on/off button to turn the
tyre repair kit on. The tyre is filled
with sealant.
The pressure gauge briefly shows a high pressure while the sealant
canister is emptying. Then the
pressure starts to drop.
All of the sealant is pumped into
the tyre. Then the tyre is inflated.
7. Inflate the tyre to the recommended inflation pressure
using the pressure gauge. The
prescribed tyre pressure should
be obtained within 10 minutes
