Maintenance and care
■Replacing the following bulbs
If any of the lights listed below has burnt out, have it replaced by your
Lexus dealer.
●Headlight low beams (discharge bulbs)
●Parking lights/daytime running lights
●Side turn signal lights
●LED fog lights (if equipped)
●Stop/tail lights
●Tail lights
●Rear side marker lights
●High mounted stoplight
●License plate lights
●Outer foot lights
■Discharge headlights (if equipped)
If voltage to the discharge bulbs is insufficient, the bulbs may not come on, or may go
out temporarily. The discharge bulbs will come on when normal power is restored.
■LED lights
The parking lights/daytime running lights, side turn signal lights, LED fog lights (if
equipped), stop/tail lights, tail lights, rear side marker lights, high mounted stoplight,
license plate lights and outer foot lights consist of a number of LEDs. If any of the
LEDs burn out, take your vehicle to your Lexus dealer to have the light replaced.
■Condensation build-up on the inside of the lens
Temporary condensation build-up on the inside of the headlight lens does not indi-
cate a malfunction. Contact your Lexus dealer for more information in the following
situations:
●Large drops of water have built up on the inside of the lens.
●Water has built up inside the headlight.

CAUTION
■Replacing light bulbs
●Turn off the lights. Do not attempt to replace the bulb immediately after turning
off the lights.
The bulbs become very hot and may cause burns.
●Do not touch the glass portion of the light bulb with bare hands. When it is
unavoidable to hold the glass portion, use and hold with a clean dry cloth to avoid
getting moisture and oils on the bulb.
Also, if the bulb is scratched or dropped, it may blow out or crack.
●Fully install light bulbs and any parts used to secure them. Failure to do so may
result in heat damage, fire, or water entering the headlight unit. This may damage
the headlights or cause condensation to build up on the lens.
■Discharge headlights (if equipped)
●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 25000 V will 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.

When trouble arises
CAUTION
■Maintenance of the tires
Each tire, including the spare (if provided), should be checked monthly when cold
and inflated to the inflation pressure recommended by the vehicle manufacturer on
the vehicle placard or tire inflation pressure 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 [tire 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 warning 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 reached 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 the 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.
