3587-2. Steps to take in an emergency
■Brake hold operated indicator (warning buzzer)
■Master warning light (warning buzzer)
■Warning buzzer
In some cases, the buzzer may not be heard
due to being in a noisy location or audio
sound.
■Front passenger detection sensor, seat
belt reminder and warning buzzer
●If luggage is placed on the front passen-
ger 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 sen-
sor may not detect a passenger, and the
warning light may not operate properly.
■SRS warning light
This warning light system monitors the air-
bag sensor assembly, front impact sensors,
side impact sensors (front door), side
impact sensors (front), side impact sensors
(rear), driver’s seat position sensor, driver’s
seat belt buckle switch, front passenger
occupant classification system (ECU and
sensors), “PASSENGER AIR BAG” indica-
tor lights, front passenger’s seat belt buckle
switch, seat belt pret ensioners, airbags,
interconnecting wiring and power sources.
(  P.28)
■Electric power steering system warning
light (warning buzzer)
When the battery charge becomes insuffi-
cient or the voltage temporarily drops, the electric power steering system warning
light may come on and the warning buzzer
may sound.
■When the tire pressure warning light
comes on
Inspect the tires to check if a tire is punc-
tured.
If a tire is punctured: P.365
If none of the tires are punctured:
Turn the engine switch off then turn it to
IGNITION ON mode. Check if the tire
pressure warning light comes on or blinks.
If the tire pressure warning light blinks for
approximately 1 minute then stays on
There may be a malfunction in the tire pres-
sure warning system. Have the vehicle
inspected by your Lexus dealer immedi-
ately.
If the tire pressure warning light comes
on
1 After the temperature of the tires has
lowered sufficiently, check the inflation
pressure of each tire and adjust them to
the specified level.
2 If the warning light does not turn off
even after several minutes have
elapsed, check that the inflation pres-
sure of each tire is at the specified level
and perform initialization. ( P.324)

3607-2. Steps to take in an emergency
WARNING
As an added safety feature, your vehicle
has been equipped with a tire pressure
monitoring system (TPMS-tire pressure
warning system) that illuminates a low
tire pressure telltale (tire pressure warn-
ing light) when one or more of your tires
is significantly under-inflated. Accord-
ingly, when the low tire pressure telltale
(tire pressure warning light) illuminates,
you should stop and check your tires as
soon as possible, and inflate them to the
proper pressure. Driving on a signifi-
cantly under-inflated tire causes the tire
to overheat and can lead to tire failure.
Under-inflation also reduces fuel effi-
ciency and tire tread life, and may affect
the vehicle’s handling and stopping abil-
ity.
Please note that the TPMS (tire pressure
warning system) is not a substitute for
proper tire maintenance, and it is the
driver’s responsibility to maintain correct
tire pressure, even if under-inflation has
not reached the level to trigger illumina-
tion of the TPMS low tire pressure telltale
(tire pressure warning light).
Your vehicle has also been equipped
with a TPMS (tire pressure warning sys-
tem) malfunction indicator to indicate
when the system is not operating prop-
erly. The TPMS (tire pressure warning
system) malfunction indicator is com-
bined with the low tire pressure telltale
(tire pressure warnin g light). When the
system detects a malfunction, the telltale
will flash for approximately one minute
and then remain continuously illumi-
nated. This sequence will continue upon
subsequent vehicle start-ups as long as
the malfunction exists. When the mal-
function indicator is illuminated, the sys-
tem may not be able to detect or signal
low tire pressure as intended.
TPMS (tire pressure warning system)
malfunctions may occur for a variety of
reasons, including th e installation of
replacement or alternate tires or wheels
on the vehicle that prevent the TPMS
(tire pressure warning system) from
functioning properly. Always check the
TPMS (tire pressure warning system)
malfunction telltale after replacing one
or more tires or wheels on your vehicle
to ensure that the replacement or alter-
nate tires and wheels allow the TPMS
(tire pressure warning system) to con-
tinue to function properly.
NOTICE
■To ensure the tire pressure warning
system operates properly
Do not install tires wi th different specifi-
cations or makers, as the tire pressure
warning system may not operate prop-
erly.

When trouble arises
WARNING
•TRAC
• Dynamic radar cruise control with full-speed range
• PCS (Pre-Collision System)
•EPS
• Adaptive Variable Suspension system (if equipped)
• LTA (Lane Tracing Assist)
• Panoramic view monitor (if equipped)
• Lexus parking assist monitor (if equipped)
• Intuitive parking assist (if equipped)
• Navigation system (if equipped)
• BSM (Blind Spot Monitor)
• AHB (Automatic High Beam)
Also, not only can the following system
not be utilized fully, but it may even nega-
tively affect the drive-train components:
• AWD system (if equipped)
■Speed limit when using the compact
spare tire
Do not drive at speeds in excess of 50
mph (80 km/h) when a compact spare
tire is installed on the vehicle.
The compact spare tire is not designed
for driving at high speeds. Failure to
observe this precaution may lead to an
accident causing death or serious injury.
■After using the tools and jack
Before driving, make sure all the tools
and jack are securely in place in their
storage location to reduce the possibility
of personal injury during a collision or
sudden braking.
NOTICE
■Be careful when driving over bumps
with the compact spare tire installed
on the vehicle
The vehicle becomes lower when driving
with the compact spare tire compared to
when driving with standard tires. Be
careful when driving over uneven road
surfaces.
■Driving with tire chains and the com-
pact spare tire
Do not fit tire chains to the compact
spare tire.
Tire chains may damage the vehicle
body and adversely affect driving perfor-
mance.
■When replacing the tires
When removing or fitting the wheels,
tires or the tire pressure warning valve
and transmitter, contact your Lexus
dealer as the tire pressure warning valve
and transmitter may be damaged if not
handled correctly.
