5-2. Steps to take in an emergency
Vehicles with standard tires
● If the warning light is on, the tire inflation pressure is lower than specified
Stop your vehicle at a safe place as soon as possible.
Check and adjust the tire inflation pressure as specified on the tire and
loading information label. (P.219) If the warning light comes on or
blinks even after tire inflation pressure adjustment, it is probable that you
have a flat tire.
If the tire goes flat, change to the spare tire. (P. 27 0)
The warning light remains on even if the spare tire is mounted.
● If the low tire pressure warning light blinks and chimes sound every few minutes,
the tire inflation pressure is very low
Stop your vehicle at a safe place as soon as possible.
Check the tire inflation pressure and locate the deflated tire. (P.21 9 )
Change to the spare tire. (P.27 2 )
The warning light remains on even if the spare tire is mounted.
■ The low tire pressure warning light may turn on due to natural causes
The warning light may turn on due to natural causes such as natural air leaks or tire
inflation pressure changes caused by temperature. In this case, adjusting the tire
inflation pressure will turn off the warning light.
■ If the low tire pressure warning light does not go off more than 15 minutes after
air is put in the deflated tire
If there is no flat tire, the system might be malfunctioning. Consult your Lexus
dealer.
■ If you drive at high speed with the tires not inflated at the designated pressure for
high speed driving
The low tire pressure warning light may turn on. In this case, decreasing the speed
will turn off the warning light.
