Selecting “Comfort pressure” in the
Tire pressure menu
Available setting options:
– “
Comfort
”
– “
Standard
”
For speeds up to 100 mph (160 km/h), the tire
pressures can be reduced to increase driving
comfort.
The Tire Pressure Monitoring system must be set
to the applicable tire pressure (comfort pressure
or standard pressure).
If you selected “
Comfort press.
”, the TPM
system automatically uses lower pressure values
when monitoring tire pressures.
The comfort tire pressures are included in the
technical data
or
under “
Fill info
” in the “
Tire
pressure
” menu, you can compare the pressure
differences (e.g. 4.4 psi / +0.3 bar / 30 kPa) with
the “Comfort pressures”.
For tires that have not yet been learned, the new
required tire pressures are displayed instead of
the actual tire pressures.

Please see the chapter “CHANGING A WHEEL
AND REPLACING TIRES” on page 125.
Prolonged driving at low tire pressure or even
short-term driving at high speeds on tires which
have too low a pressure is likely to result in a loss
of control of your vehicle, either due to a failure to
maintain directional control under side loads or
due to tire failure.
Tires are inflated to comfort pressure at the
factory, which is not suitable for driving at very
high speeds.
f
Always adjust the pressure in the tires to the
standard pressure setting when driving at
higher speeds.
f
Remember to adjust the setting in the Tire
Pressure Monitoring system accordingly.
Comfort pressure speed warning
If the maximum speed of the preset comfort
pressure is exceeded, a warning message
appears on the multi-purpose display.
Driving at excessive speeds when the comfort
pressure is active will eventually destroy the tires
and that can lead to a loss of control of the
vehicle, especially at high speeds.
f
Never exceed the speed specified on the
warning message.
f
Always set the standard tire pressure when
driving at higher speeds.
