This SRS airbag system has a service
reminder indicator to inform the driver of
operating problems. If either of the
following conditions occurs, this indicates
a malfunction of the airbags. Contact your
Toyota dealer as soon as possible to
service the vehicle.
The light does not come on when the
ignition key is turned to the ”ACC” or
”ON” position, or remains on.
The light comes on or flashes while
driving.
In the following cases, contact your Toyota
dealer as soon as possible:
The SRS airbags have been inflated.
The front part of the vehicle (shaded
in the illustration) was involved in an
accident not of the extent to cause the
SRS airbags to inflate.
The pad section of the steering wheel
or front passenger airbag cover
(shaded in the illustration) is scratched,
cracked, or otherwise damaged.
NOTICE
Do not disconnect the battery cables
before contacting your Toyota dealer.
Toyota strongly urges the use of child
restraint systems for children small
enough to use them.
The laws of all fifty states in the U.S.A.
and Canada now require the use of a
child restraint system.
Your vehicle conforms to SAE J1819.
If a child is too large for a child restraint
system, the child should sit in the rear
seat and must be restrained using the
vehicle’s seat belt. See ”Seat belts” for
details.
CAUTION
For effective protection in automo-
bile accidents and sudden stops,
children must be properly re-
strained using a seat belt or child
restraint system depending on the
age and size of the child. Holding
a child in your arms is not a sub-
stitute for a child restraint system.
In an accident, the child can be
crushed against the windshield, or
between you and the vehicle’s inte-
rior.

This model sold in Canada is provided
with a bracket set in the glove box, de-
signed for use with any of the 3 anchor
locations shown in the illustrations.
If your child restraint system does not
provide any of the necessary parts, ask
your Toyota dealer. (See ”—Child restraint
system”.)
Tilt steering wheel
To change the steering wheel angle,
hold the steering wheel, pull the lock
release lever toward you, tilt the steer-
ing wheel to the desired angle and re-
lease the lever.
When the steering wheel is in a low posi-
tion, it will spring up as you release the
lock release lever.
CAUTION
Do not adjust the steering wheel
while the vehicle is moving.
After adjusting the steering wheel,
try moving it up and down to make
sure it is locked in position.
Outside rear view mirrors—
Adjust the mirror so that you can just
see the side of your vehicle in the mir-
ror.
Be careful when judging the size or dis-
tance of any object seen in the outside
rear view mirror on the passenger ’s side.
It is a convex mirror with a curved sur-
face. Any object seen in a convex mirror
will look smaller and farther away than
when seen in a flat mirror.
On some models, when you push the rear
window defogger switch, the heater panels
in the outside rear view mirrors will quick-
ly clear the mirror surface.

—After changing wheels
11. Check the air pressure of the re-
placed tire.
Adjust the air pressure to the specification
designed in Part 8. If the pressure is low-
er, drive slowly to the nearest service sta-
tion and fill to the correct pressure.
Do not forget to reinstall the tire inflation
valve cap as dirt and moisture could get
into the valve core and possibly cause air
leakage. If the cap is missing, have a new
one put on as soon as possible.
12. Restow all the tools, jack and flat
tire securely.
As soon after changing wheels as pos-
sible, tighten the wheel nuts to the torque
specified in Part 8 with a torque wrench
and have a technician repair the flat tire.

tem reset switch.
Initial adjustment of the tire pressure
warning system is necessary after you
have replaced your tires or wheels. See
”Tire pressure warning system” in Chapter
1−8.CAUTION
Before driving, make sure all the
tools, jack and flat tire are securely
in place in their storage location to
reduce the possibility of personal in-
jury during a collision or sudden
braking.

High pressure water or steam is effec-
tive for cleaning the vehicle’s underside
and wheel housings. Pay particular
attention to these areas as it is difficult
to see all the mud and dirt. It will do
more harm than good to simply wet the
mud and debris without removing them.
The lower edge of doors, rocker panels
and frame members have drain holes
which should not be allowed to clog
with dirt as trapped water in these
areas can cause corrosion.
Wash the underside of the vehicle thor-
oughly when winter is over.
See ”Washing and waxing your Toyota” for
more tips.
Check the condition of your vehicle’s
paint and trim. If you find any chips or
scratches in the paint, touch them up im-
mediately to prevent corrosion from start-
ing. If the chips or scratches have gone
through the bare metal, have a qualified
body shop make the repair.Check the interior of your vehicle. Wa-
ter and dirt can accumulate under the
floor mats and could cause corrosion. Oc-
casionally check under the mats to make
sure the area is dry. Be particularly care-
ful when transporting chemicals, cleans-
ers, fertilizers, salt,
e tc.; these should be
transported in proper containers. If a spill
or leak should occur, immediately clean
and dry the area.
Use mud shields on your wheels. If you
drive on salted or gravel roads, mud
shields help protect your vehicle. Full−size
shields, which come as near to the ground
as possible, are the best. We recommend
that the fittings and the area where the
shields are installed be treated to resist
corrosion. Your Toyota dealer will be
happy to assist in supplying and installing
the shields if they are recommended for
your area.
Keep your vehicle in a well ventilated
garage or a roofed place. Do not park
your vehicle in a damp, poorly venti-
lated garage. If you wash your vehicle in
the garage, or if you drive it in covered
with water or snow, your garage may be
so damp it will cause corrosion. Even if
your garage is heated, a wet vehicle can
corrode if the ventilation is poor.Washing your Toyota
Keep your vehicle clean by regular
washing.
The following cases may cause weakness
to the paint or corrosion to the body and
parts. Wash your vehicle as soon as pos-
sible.
When driving in a coastal area
When driving on a road sprinkled with
antifreeze
When having stuck of coal tar, tree
sap, bird droppings and carcass of an
insect
When driving in the areas where there
is a lot of smoke, soot, dust, iron dust
and chemical substance
When the vehicle becomes remarkably
dirty with dust and mud
Hand−washing your Toyota
Work in the shade and wait until the
vehicle body is not hot to the touch.
CAUTION
When cleaning under floor or chassis,
be careful not to injure your hands.

Clean all dirt from outside of the reservoir
tank and look at the fluid level. If the fluid
is cold, the level should be in the ”COLD”
range. Similarly, if it is hot, the fluid level
should be in the ”HOT” range. If the level
is at the low side of either range, add
automatic transmission fluid DEXRONII
or III to bring the level within the range.
To remove the filler cap, turn it counter-
clockwise and lift up. To reinstall it, turn
it clockwise. After replacing the filler
cap,visually check the steering box case,
vane pump and hose connections for
leaks or damage.
CAUTION
The reservoir tank may be hot so be
careful not to burn yourself.
NOTICE
Avoid overfilling, or the power steer-
ing could be damaged.
Checking tire pressure
Keep your tire pressures at the proper
level.
The recommended cold tire pressures, tire
size and the vehicle capacity weight are
given in Part 8. They are also on the tire
pressure label as shown.
You should check the tire pressures every
two weeks, or at least once a month. And
don’t forget the spare!
Incorrect tire pressure can reduce tire
life and make your vehicle less safe to
drive.Low tire pressure results in excessive
wear, poor handling, reduced fuel econo-
my, and the possibility of blowouts from
overheated tires. Also, low tire pressure
can cause poor sealing of the tire bead.
If the tire pressure is excessively low,
there is the possibility of wheel deforma-
tion and/or tire separation.
High tire pressure produces a harsh ride,
handling problems,excessive wear at the
center of the tire tread, and a greater
possibility of tire damage from road haz-
ards.
If a tire frequently needs refilling, have it
checked by your Toyota dealer.
The following instructions for checking
tire pressure should be observed:
The pressure should be checked only
when the tires are cold. If your ve-
hicle has been parked for at least 3
hours and has not been driven for
more than 1.5 km or 1 mile since, you
will get an accurate cold tire pressure
reading.
Always use a tire pressure gauge.
The appearance of a tire can be mis-
leading. Besides, tire pressures that
are even just a few pounds off can
degrade handling and ride.

CAUTION
Do not mix radial, bias belted, or
bias−ply tires on your vehicle. It
can cause dangerous handling char-
acteristics, resulting in loss of con-
trol.
Do not use tires or wheels other
than the manufacturer ’s recom-
mended size.
Toyota recommends all four tires, or at
least both of the front or rear tires be
replaced at a time as a set.
See ”If you have a flat tire” in Part 4 for
tire change procedure.
When a tire is replaced, the wheel
should always be balanced.
An unbalanced wheel may affect vehicle
handling and tire life. Wheels can get out
of balance with regular use and should
therefore be balanced occasionally.
When replacing a tubeless tire, the air
valve should also be replaced with a
new one.
Rotating tires
Steel wheels with a compact spare tire
and aluminum wheels
Steel wheels without a compact spare tire
To equalize the wear and help extend
tire life, Toyota recommends that you
rotate your tires approximately every
12000 km (7500 miles). However, the
most appropriate timing for tire rotation
may vary according to your driving hab-
its and road surface conditions.
See ”If you have a flat tire” in Part 4 for
tire change procedure.
When rotating tires, check for uneven
wear and damage. Abnormal wear is usu-
ally caused by incorrect tire pressure, im-
proper wheel alignment, out−of−balance
wheels, or severe braking.
CAUTION
Do not include a compact spare tire
when rotating the tires. It is designed
for temporary use only.

WHEN TO USE SNOW TIRES OR
CHAINS
Snow tires or chains are recommended
when driving on snow or ice.
On wet or dry roads, conventional tires
provide better traction than snow tires.
SNOW TIRE SELECTION
If you need snow tires, select the same
size, construction and load capacity as
the original tires on your Toyota.
Do not use tires other than those men-
tioned above. Do not install studded tires
without first checking local regulations for
possible restrictions.
SNOW TIRE INSTALLATION
Snow tires should be installed on all
wheels.
Installing snow tires on the front wheels
only can lead to an excessive difference
in road grip capability between the front
and rear tires which could cause loss of
vehicle control.
When storing removed tires, you should
store them in a cool dry place. Mark the
direction of rotation and be sure to install
them in the same direction when replac-
ing.CAUTION
Do not drive with the snow tires
incorrectly inflated.
Never drive over 120 km/h (75 mph)
with any type of snow tires.
TIRE CHAIN SELECTION
Use the tire chains of correct size and
type.
Use SAE Class ”S” type radial tire chains
except radial cable chains or V−bar type
chains.
Regulations regarding the use of tire
chains vary according to location or
type of road, so always check them
before installing chains.
CHAIN INSTALLATION
Install the chains on the front tires as
tightly as possible. Do not use tire
chains on the rear tires. Retighten
chains after driving 0.5—1.0 km
(1/4—1/2 mile).
When installing chains on your tires, care-
fully follow the instructions of the chain
manufacturer.If wheel covers are used, they will be
scratched by the chain band,so remove
the covers before putting on the chains.
CAUTION
Do not exceed 50 km/h (30 mph) or
the chain manufacturer ’s recom-
mended speed limit, whichever is
lower.
Drive carefully avoiding bumps,
holes, and sharp turns, which may
cause the vehicle to bounce.
Avoid sharp turns or locked−wheel
braking, as use of chains may ad-
versely affect vehicle handling.
NOTICE
Do not attempt to use a tire chain on
the compact spare tire, as it may re-
sult in damage to the vehicle as well
as the tire.
