INFORMATION
■
If the tire pressure warning light comes on
Inspect the tires to check if a tire is punctured.
If a tire is punctured:
●
If none of the tires are punctured: Turn the engine switch off then turn it to ON. Check
●
if the tire pressure warning light comes on or blinks.
•
If the tire pressure warning light blinks for approximately 1 minute then stays on
There may be a malfunction in the tire pressure warning system. Have the vehicle
inspected by your Lexus dealer immediately.
•
If the tire pressure warning light comes on
After the temperature of the tires has lowered sufficiently, check the inflation
pressure of each tire and adjust them to the specified level.
If the warning light does not turn off even after several minutes have elapsed, check
that the inflation pressure of each tire is at the specified level and perform the tire
inflation pressure setting procedure.
If the warning light does not turn off even after several minutes have elapsed since
performing the tire inflation pressure setting procedure, have the vehicle inspected
by your Lexus dealer immediately.
■
The tire pressure warning light may come on due to natural causes
The tire pressure warning light may come on due to natural causes such as natural air
leaks and tire inflation pressure changes caused by temperature. In this case, adjusting
the tire inflation pressure will turn off the warning light (after a few minutes).
■
When a tire is replaced with a spare tire (vehicles with a compact spare tire)
The spare tire is not equipped with a tire pressure warning valve and transmitter. If a tire
goes flat, the tire pressure warning light will not turn off even though the flat tire has been
replaced with the spare tire. Replace the spare tire with the repaired tire and adjust the
tire inflation pressure. The tire pressure warning light will go off after a few minutes.
WARNING
■
If the tire pressure warning light comes on
Be sure to observe the following precautions. Failure to do so could cause a loss of
vehicle control and result in death or serious injury.
●
Vehicles with run-flat tires:
Decelerate to the lowest appropriate speed as soon as possible. Do not drive over 50
mph (80 km/h).
Stop your vehicle in a safe place as soon as possible. Adjust the tire inflation pressure
●
immediately.
