When trouble arises
339 5−2. Steps to take in an emergency
CAUTION
TPMS (tire pressure warning system ) malfunction may occur for a vari−
ety of reasons, including the installati
on of replacement or alternate tires
or wheels on the vehicle that prevent the TPMS (tire pressure warning
system) from functioning properly. Always check the TPMS (tire pres−
sure warning system) malfunction te
lltale after replacing one or more
tires or wheels on your vehicle to ensure that the replacement or alter−
nate tires and wheels allow the TPMS (tire pressure warning system) to
continue to function properly.
If the tire pressure warning light comes on
Be sure to observe the following precautions. Failure to do so could
cause loss of vehicle control and result in death or serious injury.
Stop your vehicle in a safe place as
soon as possible. Adjust the tire
inflation pressure immediately.
If the tire pressure warning light comes on even after tire inflation pres−
sure adjustment, it is probable that you have a flat tire. Check the tires.
If the tire is flat, change to the spare tire and have the flat tire repaired
by the nearest Toyota dealer.
Avoid abrupt maneuvering and braking. If the vehicle tires deteriorate,
you could lose control of the steering wheel or the brakes.
If a blowout or sudden air leakage should occur
The tire pressure warning system may not activate immediately.
NOTICE
Precaution when installing a different tire
When a tire of a different specification or maker is installed, the tire pres−
sure warning system may
not operate properly.
