MOBILITY
Icon Possible cause
There is a tire pressure loss.
No reset was performed for the sys-
tem. The system issues a warning
based on the tire inflation pressures
stored during the last reset.
Measure
1. Reduce the vehicle speed. Do not exceed a
speed of 80 mph/130 km/h.
2. At the next opportunity, for instance at a fill-
ing station, check the tire inflation pressure
in all four tires and correct if necessary.
3. Perform a system reset.
If there is a significant tire pressure
loss
Message
A yellow warning light is illuminated in
the instrument cluster.
In addition, an icon with the affected tire ap-
pears in a Check Control message on the con-
trol display.
Icon Possible cause
There is a flat tire or a major tire
pressure loss.
No reset was performed for the sys-
tem. The system issues a warning
based on the tire inflation pressures
stored during the last reset.
Measure
1. Reduce your speed and stop cautiously.
Avoid sudden braking and steering maneu-
vers.
2. Read the description on what to do in case
of a flat tire.
Actions in the event of a flat tire, refer to
page 332.

Actions in the event of a flat tire
1. Identify the damaged tire.
Check the tire pressure in all four tires,
for instance using the tire pressure display
from a tire repair set.
For tires with special approval: when the
tire pressure in all four tires is correct, the
Tire Pressure Monitor may not have been
reset. In this case, perform the reset.
If no tire damage can be identified, con-
tact an authorized service center or another
qualified service center or repair shop.
2. Repair the flat tire, for instance with a tire
repair set or by changing the wheel.
Using a sealing compound, for instance
from the tire repair set, may damage the
wheel electronics. Have the electronics re-
placed at the next opportunity.
System limits
Temperature
The tire inflation pressure depends on the
tire's temperature.
Driving or exposure to the sun will increase the
tire temperature, thus increasing the tire infla-
tion pressure.
The tire inflation pressure is reduced when the
tire temperature falls again.
These circumstances may cause a warning
when temperatures fall very sharply.
Following a temperature-related warning, the
target pressures are displayed on the Control
Display again after a short distance.
Sudden tire pressure loss
The system cannot indicate sudden and se-
rious tire damage caused by external circum-
stances.
