■Replacing the following bulbs
If any of the lights listed below has burnt out, have it replaced by
your Toyota dealer.
● Headlights low beam (LED type)
● Headlights high beam (LED type)
● Front turn signal lights (LED type)
● Front side marker lights (LED type)
● Fog lights (LED type)
● Parking lights (LED type)
● Daytime running lights (LED type)
● High mounted stoplight (vehicles with cargo lamp)
● Side turn signal lights (if equipped)
■LED Lights
The side turn signal lights (if equipped), parking lights (LED type), daytime
running light (LED type) and, high mounted stoplight (vehicles with cargo
lamp) consist of a number of LEDs. If any of the LEDs burn out, take your
vehicle to your Toyota dealer to have the light replaced.
■ Condensation build-up on the inside of the lens
Toyota lamps are vented to all surrounding environmental conditions and may
experience temporary condensation build-up that is visible from outside of the
lamp. Condensation and fogging does not indicate a malfunction of the lamp
assembly. It is normal for condensation to improve and disappea r after time
and normal driving use. Visible pools of water or large droplets are a sign of a
lamp in which the seal has malfunctioned. If this is the case o r condensation
and fogging remain after long periods of time, contact your Toyota dealer for
more information.

Maintenance and care
WARNING
■Replacing light bulbs
● Turn off the lights. Do not attempt to replace the bulb immedia tely 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 hand s. When it is
unavoidable to hold the glass portion, use and hold with a clea n 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 headligh t unit. This
may damage the lights or cause condensation to build up on the lens.
● Do not attempt to repair or disassemble the bulb, bulb base, el ectrical wir-
ing, or subcomponents.
Doing so could result in electric shock and 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
WARNING
■If both the ABS and the brake system warning lights remain on
Stop your vehicle in a safe place immediately and contact your Toyota
dealer. The vehicle will become extremely unstable during braki ng, and the
ABS system may fail, which could cause an accident resulting in death or
serious injury.
■ If the tire pressure warning light comes on (if equipped)
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 infla-
tion pressure immediately.
● If the tire pressure warning light comes on even after tire inf lation 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 Toyota dealer.
● Avoid abrupt maneuvering and braking. If the vehicle tires dete riorate, 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.
■
Maintenance of the tires (vehicles with the tire pressure warning
system)
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 p ressure
label (tire and load information label). (If your vehicle has t ires of a dif-
ferent size than the size indicated on the vehicle placard or t ire inflation
pressure label [tire and load information label], you should de termine
the proper tire inflation p ressure 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 significantly under-inflated. Accord-
ingly, when the low tire pressure telltale (tire pressure warni ng light)
illuminates, you should stop and check your tires as soon as po ssible,
and inflate them to the proper pressure. Driving on a significa ntly
under-inflated tire causes the tire to overheat and can lead to tire fail-
ure. Under-inflation also reduces fuel efficiency and tire tread life, and
may affect the vehicle’s handling and stopping ability.

4887-2. Steps to take in an emergency
WARNING
Please note that the TPMS (tire pressure warning system) is not a sub-
stitute for proper tire maintenance, and it is the driver’s res ponsibility 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 warn-
ing system) malfunction indicato r to indicate when the system is not
operating properly. The TPMS (tire pressure warning system) mal func-
tion indicator is combined with the low tire pressure telltale (tire pressure
warning light). When the system detects a malfunction, the tell tale will
flash for approximately one minute and then remain continuously illumi-
nated. This sequence will continue upon subsequent vehicle star t-ups
as long as the malfunction exists . When the malfunction indicator is illu-
minated, the system may not be able to detect or signal low tir e pres-
sure as intended.
TPMS (tire pressure warning system) malfunctions may occur for a vari-
ety of reasons, including the installation of replacement or alternate tires
or wheels on the vehicle that prevent the TPMS (tire pressure w arning
system) from functioning properly. Always check the TPMS (tire pres-
sure 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
continue to function properly.
NOTICE
■To ensure the tire pressure warning system operates properly (i f
equipped)
Do not install tires with differ ent specifications or makers, a s the tire
pressure warning system may not operate properly.
