CheckTirePressureSoonCanada only:
The tire pressure loss warning system has detected a significant loss
in pressure.
A warning tone also sounds.
Possible causes:
Ryou have changed the positions of the wheels and tires or installed
new wheels and tires.
Rthe tire pressure in one or more tires has dropped
GWARNING
Tire pressures that are too low pose the following hazards:
Rthey may burst, especially as the load and vehicle speed increase.
Rthey may wear excessively and/or unevenly, which may greatly
impair tire traction.
Rthe driving characteristics, as well as steering and braking, may be
greatly impaired.
There is a risk of an accident.
XStop the vehicle without making any sudden steering or braking
maneuvers. Pay attention to the traffic conditions as you do so.
XSecure the vehicle against rolling away (Ypage 189).
XCheck the tires and, if necessary, follow the instructions for a flat
tire (Ypage 367).
XCheck the tire pressures and, if necessary, correct the tire pressure.
XRestart the tire pressure loss warning system when the tire pres-
sure is correct (Ypage 394).
CheckTirePressureThen Restart RunFlat Indicator
Canada only:
The tire pressure loss warning system generated a display message
and has not been restarted since.
XSet the correct tire pressure in all four tires.
XRestart the tire pressure loss warning system (Ypage 394).
Run Flat IndicatorInoperativeCanada only:
The tire pressure loss warning system is faulty.
XVisit a qualified specialist workshop.
PleaseCorrectTirePressureThe tire pressure is too low in at least one of the tires, or the tire
pressure difference between the wheels is too great.
XCheck the tire pressures at the next opportunity (Ypage 390).
XIf necessary, correct the tire pressure.
XRestart the tire pressure monitor (Ypage 392).
