Messages
General information
A low tire inflation pressure may cause the DSC
Dynamic Stability Control to be switched on.
Safety information
WARNING
A damaged regular tire with low or missing tire
inflation pressure impacts handling, such as
steering and braking response. There is a risk
of an accident. Do not continue driving. Repair
the flat tire or replace the wheel.
If a tire inflation pressure check is
required
Message
A symbol with a Check Control message ap‐
pears on the Control Display.
Symbol Possible cause
The system has detected a wheel
change, but no reset was done.
Inflation was not carried out according
to specifications.
The tire inflation pressure has fallen
below the level of the last confirma‐
tion.
Measure
1. Check the tire pressure and correct as
needed.
2. Carry out a reset of the system after a tire
change.
At low tire inflation pressure
Message
A yellow warning light is illuminated in
the instrument cluster.
In addition, a symbol with a Check Control mes‐
sage appears on the Control Display.
Symbol Possible cause
There is a flat tire or a major loss in
tire inflation pressure.
No reset was performed for the sys‐
tem. The system therefore issues a
warning based on the tire inflation
pressures before the last reset.
Measure
Reduce your speed and stop cautiously. Avoid
sudden braking and steering maneuvers. Do not
keep driving and contact a dealer’s service cen‐
ter or another qualified service center or repair
shop.
If no tire repair kit is available, contact a dealer’s
service center or another qualified service center
or repair shop.
System limits
Temperature
The tire inflation pressure depends on the tire's
temperature.
Driving or exposure to the sun will increase the
tire's 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.
Sudden tire pressure loss
The system cannot indicate sudden serious tire
damage caused by external circumstances.
