■Replacing light bulbs
●Turn off the lights. Do not
attempt to replace the bulb

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. Fail-
ure to do so may result in heat
damage, fire, or water entering
the light unit. This may damage
the lights or cause condensa-
tion to build up on the lens.
■When changing the back-up
lights
●Stop the engine and wait until
the exhaust pi pes and sur-

down sufficiently. The lights are
located near the exhaust pipe

When trouble arises
■If the tire pressure warning light
frequently comes on after blink-
ing for 1 minute
If the tire pressure warning light fre-
quently comes on after blinking for 1
minute when the engine switch is
turned to ON, have it checked by
your Toyota dealer.
■Warning buzzer
In some cases, the buzzer may not
be heard due to being in a noisy
location or audio sound.
WARNING
■If both the ABS and the brake
system warning lights remain
on
Stop your vehicle in a safe place
immediately and contact your Toy-
ota dealer. The vehicle will
become extremely unstable
during braking, and the ABS sys-
tem may fail, which could cause
an accident resulting in death or
serious injury.
■When the electric power
steering system warning light
comes on
The steering wheel may become
extremely heavy.
When steering wheel operations
are heavier than usual, grip the
steering wheel firmly and operate
it using more force than usual.
■If the tire pressure warning
light comes on
Be sure to observe the following
precautions. Failure to do so
could cause a loss of vehicle con-
trol and result in death or serious
injury.
●Stop your vehicle in a safe place
as soon as possible. Adjust the
tire inflation pressure immedi-
ately.
●If the tire pressure warning light
comes on even after tire infla-
tion pressure adjustment, it is
probable that you have a flat
tire. Check the tires. If a tire is
flat, repair the flat tire by using
emergency tire puncture repair
kit.
●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
The tire pressure warning system
may not activate immediately.
■Maintenance of the tires
Each tire, includi ng the spare (if
provided), should be checked
monthly when cold and inflated to
the inflation pressure recom-
mended by the vehicle manufac-
turer 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 infor-
mation label], you should deter-
mine the proper tire inflation
pressure for those tires.)
