Tyre pressure control system

Important safety notes
The tyre pressure control system serves to
enhance off-road capability and traction on
soft surfaces.
The pressures of the tyres on the front and
R
rear axles are shown in the on-board com-
puter display.
You can adjust the tyre pressure to suit the
R
terrain while driving.
A safety device limits the upper and lower
R
tyre pressures that can be set.
Pay attention to the tyre pressure table

WARNING
Underinflated or overinflated tyres pose the
following risks:
the tyres may burst, especially as the load
R
and vehicle speed increase.
the tyres may wear excessively and/or
R
unevenly, which may greatly impair tyre
traction.
the driving characteristics, as well as steer-
R
ing and braking, may be greatly impaired.
There is a risk of an accident.
Observe the recommended tyre pressure and
check the tyre pressure of all the tyres includ-
ing the spare wheel:
at least every two weeks
R
when the load changes
R
before embarking on a longer journey
R
for changed operating conditions, e.g. off-
R
road driving
If necessary, correct the tyre pressure.
Preparing for a journey
Every day, before starting a journey, check
the tyres for external damage and check the
tyre pressure in the on-board computer. The
tyre pressures are displayed in the on-board
computer display as soon as the key is turned
to position 2 in the ignition lock.
