The tyre pressure values given for low
loads are minimum values which offer you
good ride comfor tcharacteristics.
However, you can also use the values given
for higher loads. These are permissible and
will not adversely affect the running of the
vehicle. Checking the tyre pressures
Important safety notes Observe the notes on tyre pressure:
(Y
page 325).
Information on air pressure for the tyres on
your vehicle can be found:
R on the vehicle's tyre and loading informa-
tion table on the B-pillar (Y page 326)
R on the tyre pressure label on the fuel filler
flap (Y page 326)
R in the "Tyre pressure information" section
R in the "Tyre pressure information" section
(Y page 325)
Checking the tyre pressure manually To determine and set the correct tyre pres-
sure, proceed as follows:
X Remove the valve cap of the tyre that is to
be checked.
X Press the tyre pressure gauge securely
onto the valve.
X Read the tyre pressure and compare it with
the recommended value on the tyre and
loading information table on the B-pillar on
the driver's side of your vehicle
(Y page 326).
X The tyre pressure is too low: increase the
tyre pressure to the recommended value.
X The tyre pressure is too high: press down
the metal pin in the valve using the tip of a
pen, for example.
Air is released from the tyre.
X Check the tyre pressure again with the tyre
pressure gauge. X
Screw the valve cap onto the valve.
X Repeatt hese steps for the other tyres. Tyre pressure monitor
Important safety notes It is the driver's responsibility to set the tyre
pressure to the recommended cold tyre pres-
sure suitable for the operating situation
(Y
page 325). Note that the correct tyre pres-
sure for the current operating situation must
first be taught-in to the tyre pressure monitor.
if there is a substantial loss of pressure, the
warning threshold for the warning message is
aligned to the reference values taught-in.
Restart the tyre pressure monitor after
adjusting to the cold tyre pressure
(Y page 328). The current pressures are
saved as new reference values. This will
ensure that a warning message will only
appearift he tyre pressure drops significantly.
The tyre pressure monitor does not warn you
of an incorrectly set tyre pressure. Observe
the notes on the recommended tyre pressure
(Y page 325).
The tyre pressure monitor is not able to warn
you of a sudden loss of pressure, e.g. if the
tyre is penetrated by a foreign object. In the
event of a sudden loss of pressure, bring the
vehicle to a halt by braking carefully. Avoid
abrupt steering manoeuvres.
If a tyre pressure monitor system is fitted, the
vehicle's wheels have sensors fitted that
monitor the tyre pressures in all four tyres.
The tyre pressure monitor warns you when
the pressure drops in one or more of the
tyres. The tyre pressure monitor only func-
tions if the correct sensors are fitted to all
wheels.
Information on tyre pressures is displayed in
the multifunction display. After a few minutes
of driving, the current tyre pressure of each
tyre is shown in the multifunction display.
The tyre pressure values indicated by the on-
board computer may differ from those meas- Tyre pressure
