Possible causes are:
R function is impaired due to heavy rain or snow
R the radar sensor system is temporarily inoperative, e.g. due to elec-
tromagnetic radiation emitted by nearby TV or radio stations or
other sources of electromagnetic radiation
R Mercedes-AMG vehicles: ESP ®

R the system is outside the operating temperature range
R the on-board voltage is too low
When the causes stated above no longer apply, the display message

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 156).
X Check the tires and, if necessary, follow the instructions for a flat
