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 inflation pressure. Check the tire inflation
pressure with a tire pressure gauge regularly.
CAUTION
The warning system may not activate immediately if
bursts or sudden air leakage should occur.

"Tire pressure warning light
The tire pressure warning light comes on when the engine
switch "IG−ON" mode is selected, 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. At this time, the master warning light
comes on and the message "LOW TIRE" appears on the
multi−information display.
In this case, adjusting the tire inflation pressure will turn off the
light after a few minutes. If the light blinks, the tire pressure
warning system is not working properly. At this time, the
master warning light comes on and the message "CHECK
SYSTEM" appears on the multi−information display.
