Possible causes/consequences and P Solutions
Check Tire Pressure
Soon The tire pressure loss warning system has detected a significant loss
in pressure.
A warning tone also sounds.
Possible causes: R
you have changed the positions of the wheels and tires or installed
new wheels and tires. R
the tire pressure in one or more tires has dropped significantly
G WARNING
Tire pressures that are too low pose the following hazards: R
they may burst, especially as the load and vehicle speed increase. R
they may wear excessively and/or unevenly, which may greatly
impair tire traction. R
the driving characteristics, as well as steering and braking, may be
greatly impaired.
There is a risk of an accident. X
Stop the vehicle without making any sudden steering or braking
maneuvers. Pay attention to the traffic conditions as you do so. X
Secure the vehicle against rolling away ( Y
page 178).X
Check the tires and, if necessary, follow the instructions for a flat
tire ( Y
page 370). X
Check the tire pressures and, if necessary, correct the tire pressure. X
Restart the tire pressure loss warning system when the tire pres-
sure is correct ( Y
page 394).
Check Tire Pressure
Then Restart Run
Flat Indicator The tire pressure loss warning system generated a display message
and has not been restarted since. X
Set the correct tire pressure in all four tires. X
Restart the tire pressure loss warning system ( Y

Run Flat Indicator
Inoperative The tire pressure loss warning system is faulty. X
Visit a qualified specialist workshop.
Please Correct Tire
Pressure The tire pressure is too low in at least one of the tires, or the tire
pressure difference between the wheels is too great. X
Check the tire pressures at the next opportunity ( Y
page 394).X
If necessary, correct the tire pressure. X
Restart the tire pressure monitor ( Y
