7-2. Steps to take in an emergency
● Is the fuel tank cap loose?
If it is, tighten it securely.
The light will go off after several driving
trips.
If the light does not go off even after several
trips, contact your Lexus dealer as soon as
possible.
When the tire pressure warning light
■
comes on
Inspect the appearance of the tire to check
that the tire is not punctured.
If the tire is punctured: P.399
If the tire is not punctured:
Carry out the following procedure after the
tire temperature has lowered sufficiently.
● Check the tire inflation pressure and
adjust to the appropriate level.
If the warning light does not go out even
●
after several minutes, check that the tire
inflation pressure is at the specified level
and carry out initialization. (P.361)
The warning light may come on again if the
above operations are conducted without
first allowing the tire temperature to lower
sufficiently.
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, 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
■
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
P.357
If the tire pressure warning light fre-
■
quently comes on after blinking for 1
minute
If the tire pressure warning light frequently
comes on after blinking for 1 minute when
the power switch is turned to ON mode,
have it checked by your Lexus dealer.
Warning buzzer
■
In some cases, the buzzer may not be heard
due to being in a noisy location or audio
sound.
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
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. Adjust the tire infla-
tion pressure immediately.
