Maintenance and care
CAUTION
■Discharge headlights
●Contact your Lexus dealer before replacing the discharge headlights (including
light bulbs).
●Do not touch the discharge headlight’s high voltage socket when the headlights
are turned on.
An extremely high voltage of 30000 V wi ll be discharged and could result in
death or serious injury by electric shock.
●Do not attempt to take apart or repair the headlight bulbs, connectors, power
supply circuits, or related components.
Doing so could result in electric shock and death or serious injury.
■To prevent damage or fire
●Make sure bulbs are fully seated and locked.
●Check the wattage of the bulb before installing to prevent heat damage.

CAUTION
■Maintenance of the tires
Each tire, including the spare (if provided), should be checked monthly when cold
and inflated to the inflation pressure re commended by the vehicle manufacturer on
the vehicle placard or tire inflation pressu re label (tire and load information label).
(If your vehicle has tires of a different size than the size indicated on the vehicle
placard or tire inflation pressure label [t ire and load information label], you should
determine the proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle has been equipped with a tire pressure
monitoring system (TPMS-tire pressure wa rning system) that illuminates a low tire
pressure telltale (tire pressure warning light ) when one or more of your tires is sig-
nificantly under-inflated. Accordingly, when the low tire pressure telltale (tire pres-
sure warning light) illuminates, you should stop and check your tires as soon as
possible, and inflate them to the proper pressure. Driving on a significantly under-
inflated tire causes the tire to overheat and can lead to tire failure. Under-inflation
also reduces fuel efficiency and tire tread life, and may affect the vehicle’s handling
and stopping ability.
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 re ached the level to trigger illumination of
the TPMS low tire pressure telltale (tire pressure warning light).
Your vehicle has also been equipped with a TPMS (tire pressure warning system)
malfunction indicator to indicate when th e system is not operating properly. The
TPMS (tire pressure warning system) malfunction indicator is combined with the
low tire pressure telltale (tire pressure warning light). When the system detects a
malfunction, the telltale will flash for approximately one minute and then remain
continuously illuminated. This sequence will continue upon subsequent vehicle
start-ups as long as the malfunction exists . When the malfunction indicator is illumi-
nated, the system may not be able to detect or signal low tire pressure as intended.

*: Refer to the separate “Scheduled Maintenance” or “Owner’s Manual Supple-ment” for the maintenance interval applicable to your vehicle.
Wa r n i n g m e s s a g eDetailsCorrection procedure
Indicates that the tire
position information can-
not be recognized
Drive for a short while
and check if the display
updates. If the radio wave condi-
tions improve, the dis-
play may return to
normal. If the tire pres-
sure is still not dis-
played after driving for
several minutes, stop
the vehicle in a safe
place, turn the engine
switch off then on
again, and start driving.
If the tire pressure is still
not displayed even
after repeating this sev-
eral times, have the
vehicle inspected at
your Lexus dealer.
Indicates that the pre-col-
lision system is not cur-
rently functional because
the grille cover or the
sensor is dirtyThis message also
appears when the pre-
collision system is not
functional due to over-
heating.
Check the grille cover
and the sensor and clean
them if they are dirty. In case of overheating,
the system will become
functional once the sys-
tem cools down.
