loss in pressure.
A warning tone also sounds.
Possible causes: R
you have changed the positions of the wheels and tires or instal-
led new wheels and tires. R
the tire pressure in one or more tires is not correct.
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 189).X
Check the tires and, if necessary, follow the instructions for a
flat tire ( Y
page 387). X
