Maintenance and care
■
Lights other than the above
If any of the lights listed below has burnt out, have it replaced by
your Toyota dealer.
● Headlight low beams (discharge bulbs)
● High mounted stoplight
● Front fog lights (if equipped)
● Outer foot lights (if equipped)
■Condensation build-up on th e inside of the lens
Contact your Toyota dealer for more information in the following situations.
Temporary condensation build-up on the inside of the headlight lens does
not indicate a malfunction.
● Large drops of water are built up on the inside of the lens.
● Water has built up inside the headlight.
■ Discharge headlights
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 high mounted stoplight
The high mounted stoplight consists of a number of LEDs. If any of the LEDs
burn out, take your vehicle to your Toyota dealer to have the light replaced.

494 4-3. Do-it-yourself maintenance
CAUTION
■Replacing light bulbs
●Turn off the headlights. Do not attempt to replace the bulb immediately
after turning off the headlights.
The bulbs become very hot and may cause burns.
● Do not touch the glass portion of the light bulb with bare hands. Hold the
bulb by the plastic or metal portion.
If the bulb is scratched or dropped it may blow out or crack.
● Fully install light bulbs and any parts used to secure them. Failing 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.
● Do not attempt to take apart or repair the low beam headlight bulbs, con-
nectors, power supply circuits, or related components.
Doing so could result in electric shock and serious injury or death.
■ Discharge headlights
●Contact your Toyota dealer before replacing discharge headlights (includ-
ing light bulbs).
● Do not touch the high-intensity discharge headlight’s high voltage socket
when the headlights are turned on.
An extremely high voltage of 20000 V will be discharged and could result
in serious injury or death by electric shock.
■ To prevent damage or fire
Make sure bulbs are fully seated and locked.
NOTICE
■When installing the back door trim
To prevent damage, be careful not to pinch any of the wire harnesses or
connectors with the back door trim.

5-2. Steps to take in an emergency
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 differ-
ent 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 pr essure for those tires.)
As an added safety feature, your vehicle has been equipped with a tire
pressure monitoring system (TPMS-ti re pressure warning system) that
illuminates a low tire pressure telltal e (tire pressure warning light) when
one or more of your tires is significantly under-inflated. Accordingly,
when the low tire pressure telltale (tire pre ssure warning light) illumi-
nates, 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 effi ciency and tire tread life, and may
affect the vehicle's hand ling and stopping ability.
Please note that the TPMS (tire pressure warning system) is not a sub-
stitute for proper ti re maintenance, an d it is the driver's responsibility to
maintain correct tire pressure, even if under-inflation has not reached the
level to trigger illu mination of the TPMS low ti re pressure telltale (tire
pressure warning light).
