WARNING
■Replacing light bulb
●Turn off the light. Do not attempt
to replace the bulb immediately
after turning off the light.
The bulb 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 bulb and any
parts used to secure it. Failure
to do so may result in heat dam-
age, fire, or water entering the
light unit. This may damage the
light or cause condensation to
build up on the lens.
●Do not attempt t o repair or dis-
assemble light bulbs, connec-
tors, electric circuits or
component parts.
Doing so may result in death or
serious injury due to electric
shock.
■To prevent damage or fire
●Make sure bulb is fully seated
and locked.
●Check the wattage of the bulb
before installing to prevent heat
damage.

4587-2. Steps to take in an emergency
WARNING
■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.
If the steering wheel becomes
heavier than usual when operat-
ing, hold firmly and operate using
more force than usual.
■If the tire pressure warning
light comes on (vehicles with
tire pressure warning system)
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
immediately.
●If the tire pressure warning light
comes on even after tire infla-
tion pressure adjustment, it is
probable that y ou 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 (vehi-
cles with tire pressure warn-
ing system)
The tire pressure warning system
may not activate immediately.
■Maintenance of the tires
(vehicles with tire pressure
warning system)
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.)
As an added safety feature, your
vehicle has been equipped with a
tire pressure monitoring system
(TPMS-tire pressure warning sys-
tem) that illuminates a low tire
pressure telltale (tire pressure
warning light) w hen one or more
of your tires is s ignificantly under-
inflated. Accord ingly, when the
low tire pressure te lltale (tire pres-
sure warning light) illuminates,
you should stop and check your
tires as soon as possible, and
inflate them to the proper pres-
sure. 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 vehi-
cle’s handling and stopping abil-
ity.
Please note that the TPMS (tire
pressure warning system) is not a
substitute for proper tire mainte-
nance, and it is the driver’s
responsibility to m aintain correct
tire pressure, even if under-infla-
tion has not reached the level to
trigger illumination of the TPMS
low tire pressure te lltale (tire pres-
sure warning light).
