Front passenger detection sensor, seat belt reminder and warning buzzer
If luggage is placed on the front passenger seat, the front passenger detection
sensor may cause the warning light to flash and the warning buzzer to sound
even if a passenger is not sitting in the seat.
If a cushion is placed on the seat, the sensor may not detect a passenger, and the
warning light may not operate properly.
Electric power steering system warning light (warning buzzer)
When the 12-volt battery charge becomes insufficient or the voltage temporarily
drops, the electric power steering system warning light may come on and the
warning buzzer may sound.
If the malfunction indicator lamp comes on while driving
The malfunction indicator lamp will come on if the fuel tank becomes com-
pletely empty. If the fuel tank is empty, refuel the vehicle immediately. The mal-
function 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. 591, 605
If the tire is not punctured:
Carry out the following procedure after the tire temperature has lowered suffi-
ciently.
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.
512)
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 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 (after a few
minutes).

When trouble arises
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
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.
Conditions that the tire pressure warning system may not function properly (vehi-
cles with the tire pressure warning system)
P. 514
If the tire pressure warning light frequently comes on after blinking for 1 minute
(vehicles with the tire pressure warning system)

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.

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 operate using more force than usual.

If the tire pressure warning light comes on (vehicles with the tire pressure warn-
ing 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 professional.
Vehicles with an emergency tire puncture repair kit: If the tire pressure warn-
ing 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 puncture 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
warning 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 specifications or makers, as the tire pressure
warning system may not operate properly.

Improper use of the tire jack may cause the vehicle to suddenly fall off the jack,
leading to death or serious injury.
Do not use the tire jack for any purpose other than replacing tires or installing
and removing tire chains.
Only use the tire jack that comes with this vehicle for replacing a flat tire.

jack.
Do not start the hybrid system or drive the vehicle while the vehicle is sup-
ported by the jack.

Replacing a flat tire
Do not touch the disc wheels or the area around the brakes immediately after
the vehicle has been driven.
After the vehicle has been driven the disc wheels and the area around the
brakes will be extremely hot. Touching these areas with hands, feet or other
body parts while changing a tire, etc. may result in burns.
Failure to follow these precautions could cause the wheel nuts to loosen and
the tire to fall off, resulting in death or serious injury.
• Never use oil or grease on the wheel bolts or wheel nuts.
Oil and grease may cause the wheel nuts to be excessively tightened, lead-
ing to bolt or disc wheel damage. In addition, the oil or grease can cause
the wheel nuts to loosen and the wheel may fall off, causing a serious acci-
dent.
Remove any oil or grease from the wheel bolts or wheel nuts.
• Have the wheel nuts tightened with a torque wrench to 103 N•m
(10.5 kgf•m, 76 ft•lbf) as soon as possible after changing wheels.
• When installing a tire, only use wheel nuts that have been specifically
designed for that wheel.
• If there are any cracks or deformations in the bolt screws, nut threads or
bolt holes of the wheel, have the vehicle inspected by any authorized Lexus
dealer or repairer, or another duly qualified and equipped professional.
