Tire pressure warning system

The tire pressure warning system warns
you that the tire inflation pressure is
low.
The tire pressure warning system is not
a substitute for checking normal tire infla-
tion pressure. Check the tire inflation
pressure with a tire pressure gauge regu-
larly.
CAUTION
The warning system may not activate
immediately if bursts or sudden air
leakage should occur.

The tire pressure warning light comes on
when the "POWER" switch is selected in
"IG−ON" mode and goes off after a few
seconds. This means the tire pressure
warning light is operating properly. If the
tire inflation pressure becomes low, the
light comes on again. In this case, adjust-
ing the tire inflation pressure will turn off
the light after a few minutes. If the light
comes on after blinking for 1 minute, the
tire pressure warning system is not work-
ing properly.

the spare tire and have the flat tire
