The required pressure and the pressure deviation
F from the required pressure at the relevant wheel as
well as the setting for load, tyre type and size are
G
displayed.
H Example: If –0.1 bar (–1.5 psi) is displayed for the
rear right wheel, 0.1 bar (1.5 psi) must be added to
I
this tyre. The displayed pressures take into account
the tyre temperature.
J
e Always use the pressure deviation from the dis-

play or from the corresponding tyre pressure
warning to correct the tyre pressure.
L
If the tyres are not yet taught, the new required
M
pressures are displayed instead of the actual pres-
sure deviations.

The options available depend on the model and tyre

shown here may not be available.
e Before fitting tyres and wheels with dimensions

that are not available for selection in the TPM

Information
If the option Full load is not displayed, the specified
tyre pressures are valid for all types of vehicle load.
Selecting comfort or standard pressure
The tyre pressures can be reduced to increase driv-
ing comfort.
If comfort pressure is selected, Tyre Pressure Mon-
itoring automatically uses lower nominal pressure
values when monitoring tyre pressure.

Teaching in Tyre Pressure Monitoring
Tyre Pressure Monitoring begins to learn the tyres
after a wheel change, wheel transmitter replacement
or update of the tyre settings. During this process,
Tyre Pressure Monitoring recognises the wheels and
their locations. Position and pressure information is
displayed as soon as Tyre Pressure Monitoring has
assigned the wheels recognised as belonging to the
vehicle to the correct wheel positions.
During this process, the required pressures for cold
tyres (20 °C) are displayed in the PCM and a mes-
sage appears on the instrument cluster.
The tyre pressure warning light
ment cluster remains lit until all the wheels have
been taught in.
Inflating tyres
Hot filling hose
CAUTION
The compressor's filling hose can get hot during the
inflation process and can cause burns.
e Wear gloves.
The compressor is located under the cover in the
luggage compartment.
> Please refer to chapter "Luggage compartment"
on page 146.
> Read and follow the operating instructions on the
compressor.
1. Screw the compressor's filler hose onto the tyre
valve.
2. Connect the compressor to a plug socket in the
vehicle and switch on the compressor.
The tyre is inflated.
3. Check inflation pressure using the pressure
