Additionally, the tyre pressure table may also
state tyre pressures for different load condi-
tions. These are defined in the table as different
numbers of passengers and amounts of lug-
gage. The actual number of seats may vary; for
more information, please refer to the vehicle's
registration documents.
If tyre sizes are not specified, the tyre pressures
stated on the tyre pressure table apply for all
tyres approved for this vehicle.
If a tyre size precedes a tyre pressure, the fol-
lowing tyre pressure information is only valid for
that tyre size.
Use a suitable pressure gauge to check the tyre
pressure. The outer appearance of a tyre does
not permit any reliable conclusion about the tyre
pressure. You can also check the tyre pressure
using the on-board computer.
If possible, only correct tyre pressures when the
tyres are cold.
The tyres are cold:
if the vehicle has been parked with the tyres
R
out of direct sunlight for at least three hours
and
if the vehicle has not been driven further than
R
1.6 km
Depending on the ambient temperature, the
vehicle speed and the load on the tyres, the tyre
temperature and thus the tyre pressure changes
by approximately 10 kPa (0.1 bar/1.5 psi) per
10 †. Take this into account when checking the
pressure of warm tyres. Only correct the tyre
pressure if it is too low for the current operating
conditions.
Driving with tyre pressure that is too high or too
low can:
shorten the service life of the tyres
R
cause increased tyre damage
R
have a negative effect on handling character-
R
istics and thus driving safety (e.g. aquaplan-
ing)
The tyre pressure values given for low loads are
minimum values which offer you good ride com-
fort characteristics.
However, you can also use the values given for
higher loads. These are permissible and will not
adversely affect the running of the vehicle.
This improves the ride comfort of your vehicle;
however, fuel consumption may increase
slightly.
Tyre pressure monitor
General notes
If a tyre pressure monitor system is fitted, the
vehicle's wheels have sensors fitted that moni-
tor the tyre pressures in all four tyres. The tyre
pressure monitor warns you if the pressure
drops in one or more of the tyres. The tyre pres-
sure monitor only functions if the corresponding
sensors are fitted to all wheels.
Information on tyre pressures is shown in the
multifunction display. After a few minutes of
driving, the current tyre pressure of each tyre is
shown in the
Service
Service
menu of the multifunction
display; see illustration (example).
For further information on displaying this mes-
sage, refer to the "Checking the tyre pressure
electronically" section (
Tyre pressure
