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 143).
XCheck the tires and, if necessary, follow the instructions for a flat
tire (Ypage 284).
XCheck the tire pressures and, if necessary, correct the tire pressure.
XRestart the tire pressure loss warning system when the tire pres-
