When trouble arises
■If the malfunction indicator lamp comes on while driving
The malfunction indicator lamp will come on if the fuel tank becomes completely empty.
If the fuel tank is empty, refuel the vehicle immediately. The malfunction indicator lamp
will go off after several trips.
If the malfunction indicator lamp does not go off, contact any authorized Lexus dealer or
repairer, or another duly qualified and equipped professional as soon as possible.
■When the tire pressure warning light comes on (vehicles with the tire pressure warning
system)
Inspect the appearance of the tire to check that the tire is not punctured.
If the tire is punctured: →P. 539, 551
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 infla-
tion pressure is at the specified level and carry out initialization. (→P. 4 6 9 )
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 (vehicles with the
tire pressure warning system)
The tire pressure warning light may turn on du e 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 (after a few minutes).
■When a tire is replaced with a spare tire (vehicles with a compact spare tire and the tire
pressure warning system)
The compact spare tire is not equipped with a tire pressure warning valve and transmit-
ter. 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.
■Conditions that the tire pressure warning system may not function properly (vehicles
with the tire pressure warning system)
→ P. 4 7 1
■If the tire pressure warning light frequently comes on after blinking for 1 minute (vehi-
cles with the tire pressure warning system)
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 any authorized Lexus dealer or
repairer, or another duly qualified and equipped professional.
■Warning buzzer
In some cases, the buzzer may not be heard due to being in a noisy location or audio
sound.

WA R N I N G
■If both the ABS and the brake system warning lights remain on
Stop your vehicle in a safe place immediately and contact any authorized Lexus dealer
or repairer, or another duly qualified and equipped professional. 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
The steering wheel may become extremely heavy.
If the steering wheel becomes heavier than usual when operating, hold firmly and oper-
ate using more force than usual.
■If the tire pressure warning light comes on (vehicles with the tire pressure warning
system)
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.
●Stop your vehicle in a safe place as soon as possible. Adjust the tire inflation pressure
immediately.
●Vehicles with a spare tire: 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
any authorized Lexus dealer or repairer, or another duly qualified and equipped pro-
fessional.
●Vehicles with an emergency tire puncture repair kit: 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, repair the flat tire by using emergency tire punc-
ture repair kit.
●Avoid abrupt maneuvering and braking. 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 (vehicles with the tire pressure warn-
ing system)
The tire pressure warning system may not activate immediately.
NOTICE
■To ensure the tire pressure warning system operates properly (vehicles with the tire
pressure warning system)
Do not install tires with different specificatio ns or makers, as the tire pressure warning
system may not operate properly.
