7-2. Steps to take in an emergency
elapsed, check that the inflation pres-
sure of each tire is at the specified level
and perform initialization. (P.406)
The tire pressure warning light may
■
come on due to natural causes (vehicles
with tire pressure warning system)
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, adjust-
ing 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 compact spare tire)
The compact spare tire is not equipped with
a tire pressure warning valve and transmit-
ter. If a tire goes flat, the tire pressure warn-
ing 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.
■ Conditions that the tire pressure warn-
ing system may not function properly
(vehicles with tire pressure warning sys-
tem)

WARNING
If both the ABS and the brake system
■
warning lights remain on
Stop your vehicle in a safe place immedi-
ately and contact your Lexus dealer.
The vehicle will become extremely
unstable during braking, and the ABS
system may fail, which could cause an
accident resulting in death or serious
injury.
When the electric power steering
■
system warning light comes on
When the light comes on yellow, the
assist to the power steering is restricted.
When the light comes on red, the assist
to the power steering is lost and handling
operations of the steering wheel become
extremely heavy.
When steering wheel operations are
heavier than usual, grip the steering
wheel firmly and operate it using more
force than usual.
If the tire pressure warning light
■
comes on (vehicles with tire pressure
warning system)
Be sure to observe the following precau-
tions.
Failure to do so could cause a loss of
vehicle control and result in death or
serious injury.
Stop your vehicle in a safe place as
●
soon as possible. Check and adjust the
tire inflation pressure immediately.
If the tire pressure warning light comes
●
on even after tire inflation pressure
adjustment, it is probable that you have
a flat tire. Check the tires. If a tire is flat,
change it with the spare tire and have
the flat tire repaired by the nearest
Lexus dealer.
● Avoid abrupt maneuvering and brak-
ing.
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.
