■To prevent injury
Before performin g any light bulb
replacement procedure, be sure
to turn the power switch off. Fail-
ure to do so may result in burns
from hot components or a part of
your body may get caught on an
operating component, possibly
causing serious injury.
■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. 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.

●Make sure bulbs are fully
seated and locked.
●Check the wattage of the bulb
before installing to prevent heat
damage.

4107-2. Steps to take in an emergency
perature. In this case, adjusting the
tire inflation pressure will turn off the
warning light (after a few minutes).
■Conditions that the tire pres-
sure warning system may not
function properly
 P. 3 6 2
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 brak-
ing, and the ABS system may fail,
which could cause an accident
resulting in death or serious injury.
■When the electric power
steering system warning light
comes on
When the light comes on yellow,
the assist to the power steering is
restricted. When the light comes
on red, the assist to the power
steering is lost and handling oper-
ations of the steering wheel
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 control 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 deteriorate,
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.)
