WARNING
The engine compartment contains
many mechanisms and fluids that
may move suddenly, become hot,
or become electrically energized.
To avoid death or serious injury,
observe the following precautions.
■When working on the engine
compartment
●Keep hands, clothing and tools
away from the moving fan and
engine drive belt.
ItemsParts and tools●Be careful not to touch the
engine, radiator, exhaust mani-
fold, etc. right a fter driving as
they may be hot. Oil and other
fluids may also be hot.
●Do not leave anything that may
burn easily, such as paper and
rags, in the engine compart-
ment.
●Do not smoke, cause sparks or
expose an open flame to fuel or
the battery. Fuel and battery
fumes are flammable.
●Be extremely cautious when
working on the battery. It con-
tains poisonous and corrosive
sulfuric acid.
■When working near the elec-
tric cooling fan or radiator
grille
Be sure the engine switch is off.
With the engine switch in ON, the
electric cooling fa n may automati-
cally start to run if the air condi-
tioning is on and/or the coolant
temperature is high. ( P.414)
■Safety glasses
Wear safety glasses to prevent
flying or falling material, fluid
spray, etc. from getting in your
eyes.
NOTICE
■If you remove the air cleaner
filter
Driving with the air cleaner filter
removed may cause excessive
engine wear due to dirt in the air.

Maintenance and care
The recommended cold tire
inflation pressure and tire size
are displayed on the tire and
loading information label.
(P.505)
Tire valve
Tire pressure gauge
1 Remove the tire valve cap. 2
Press the tip of the tire pres-
sure gauge onto the tire
valve.
3 Read the pressure using the
gauge gradations.
4 If the tire inflation pressure is
not at the recommended
level, adjust the pressure.
If you add too much air, press
the center of the valve to
deflate.
5 After completing the tire infla-
tion pressure measurement
and adjustment, apply soapy
water to the valve and check
for leakage.
6 Put the tire valve cap back
on.
■Tire inflation pressure check
interval
You should check ti re inflation pres-
sure every two week s, or at least
once a month. Do not forget to
check the spare.
■Effects of incorrect tire inflation
pressure
Driving with incorrec t tire inflation
pressure may resul t in the following:
●Reduced fuel economy
●Reduced driving comfort and poor
handling
●Reduced tire life due to wear
●Reduced safety
●Damage to the drive train
If a tire needs frequent inflating,
have it checked by your Toyota
dealer.

When trouble arises
■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.
●Vehicles with a compact spare
tire: If the tire pr essure warning
light comes on ev en after tire
inflation 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 Toy ota dealer.
●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.)
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 significantly
under-inflated. Accordingly, when
the low tire pressure telltale (tire
pressure 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 signifi-
cantly under-inflated tire causes
the tire to overhea t 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 ability.
WARNING
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).

4867-2. Steps to take in an emergency
If the fuel filler door opener
switch cannot be operated,
remove the cover inside the
luggage compartment and
pull the lever to open the fuel
filler door.
 Using the lever to open the
fuel filler door may not allow
for an adequate reduction in
fuel tank pressure before refu-
eling. To prevent fuel from spilling out, turn the cap
slowly when removing it.
During refueling, fuel may spill
out from the filler opening due
to air being discharged from
inside the fuel tank. There-
fore, fill the fuel tank carefully
and slowly.
If the fuel filler door
cannot be opened
If the fuel filler door opener
switch cannot be operated,
contact your Toyota dealer
to service the vehicle. In
case where refueling is
urgently necessary, the fol-
lowing procedure can be
used to open the fuel filler
door.

door

5158-1. Specifications
8
Vehicle specifications
Grade C corresponds to a level of
performance which all passenger
car tires must meet under the Fed-
eral Motor Vehicle Safety Standard
No. 109.
Grades B and A represent higher
levels of performance on the labo-
ratory test wheel than the minimum
required by law. Warning: The temperature grades
of a tire assume tha
t it is properly
inflated and not overloaded.
Excessive speed, underinflation, or
excessive loading, either sepa-
rately or in combination, can cause
heat buildup and possible tire fail-
ure.
