On the Control Display
The current tire inflation pres-
sure values and the intended
tire inflation pressure values for
the mounted tires can be dis-
played on the Control Display.
To ensure that they are dis-
played correctly, the tire sizes
must be stored in the system
and must have been set, refer to
page 278, for the mounted tires.
The current tire inflation pres-
sure value is located on each
tire.
The intended tire inflation pres-
sure value is located in the
lower area of the Control Dis-
play.
Checking the tire inflation
pressure
General information
Tires heat up while driving. The
tire inflation pressure increases
with the tire temperature.
Tires have a natural, consistent
loss of tire inflation pressure.
The displays of inflation devices
may under-read by up to 0.1
bar/2 psi.

Checking using tire inflation
pressure specifications in
the tire inflation pressure
table
The tire inflation pressure speci-
fications in the tire inflation pres-
sure table only relate to cold
tires or tires at the same tem-
perature as the ambient tem-
perature.
Only check the tire inflation
pressure levels when the tires
are cold, i.e.:
• Driving range of max. 1.25
miles/2 km has not been
exceeded.
• If the vehicle has not moved
again for at least 2 hours after
a trip.
Check the tire inflation pressure
of the emergency wheel in the
cargo area regularly, and correct
it as needed.
1
Determine, refer to page 262,
the intended tire inflation
pressure levels for the
mounted tires.
2
Check the tire inflation pres-
sure in all four tires, using a
pressure gauge, for example.
3
Correct the tire inflation pres-
sure if the current tire infla-
tion pressure value deviates
from the specified value.
4
Check whether all valve caps
are screwed onto the tire
valves.
