In the following cases, contact your Toyota
dealer as soon as possible: The SRS airbag has been inflated.
The front part of the vehicle (shaded
in the illustration) was involved in an
accident that did not cause the SRS
airbag to inflate.
The pad section of the steering wheel
(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 seat
and must be restrained using the vehicle’s
seat belt. See ”Seat belts” for details.
CAUTION
For effective protection in automobile
accidents and sudden stops, children
must be properly restrained using a
seat belt or child restraint system de-
pending on the age and size of the
child. Holding a child in your arms is
not a substitute for a child restraint
system. In an accident, the child can
be crushed against the windshield, or
between you and the vehicle’s interi-
or.
Toyota strongly urges use of a
proper child restraint system which
conforms to the size of the child.
As to XTRA −cab models, the child
restraint system should be put on
the rear seat. According to accident
statistics, the child is safer when
properly restrained in the rear seat
than in the front seat.
Make sure that you have complied
with all installation instructions pro-
vided by the child restraint
manufacturer and that the system is
properly secured.

2. To remove the child restraint system,press the buckle −release button and al-
low the belt to retract. Tilt steering wheelTo change the steering wheel angle,
hold the steering wheel, pull up the
lock release lever, tilt the steering
wheel to the desired angle and release
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 you can just see
the side of your vehicle in the mirror.
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.

T100(U)123

Even though the anti-lock brake system
is operating, a driver cannot maintain
full control on certain slippery road sur-
faces, when cornering at high speeds,
or in violent maneuvers.
Avoid high speeds on wet roads. The
anti-lock brake system cannot eliminate
the risk of hydroplaning and loss of tire
friction.
Always maintain a safe distance from the
vehicle in front of you. Compared with
vehicles not fitted with an anti-lock brake
system, your vehicle may r equire a longer
stopping distance in the following cases:
Driving on rough, gravel or snow-cov-
ered roads.
Driving with tire chains installed.
Driving on roads where the road sur-
face is pitted or has other differences
in surface height.
CAUTION
Do not use tires other than the
manufacturer ’s designated tires, and
do not mix tires or wheels of differ-
ent sizes. You may prevent the anti-
lock brake system from operating at
full effectiveness.
”ABS” warning light
This light comes on when the ignition key
is turned to the ”ON” position. After about
3 seconds, the light will go off.
If either of the following conditions occurs,
this indicates a malfunction somewhere in
the parts monitored by the warning light
system. Contact your Toyota dealer as
soon as possible to service the vehicle.
The light does not come on as de-
scribed above, or remains on.
The light comes on while driving. Even if the anti-lock brake system should
fail, the brake system will still operate
conventionally. However, when the ”ABS”
warning light is on (and the brake system
warning light is off), the anti
−lock brake
system is not assisting brake performance
so that the wheels can lock −up during
sudden braking or braking on slippery
road surfaces. Have your vehicle checked
by your Toyota dealer as soon as pos-
sible.

Types of tires
Determine what kind of tires your ve-
hicle is originally equipped with.
1. Summer tires
Summer tires are high-speed capability
tires best suited to highway driving under
dry conditions.
Since summer tires do not have the same
traction performance as snow tires, sum-
mer tires are inadequate for driving on
snow-covered or icy roads. For driving on
snow-covered or icy roads, we recommend
using snow tires. If installing snow tires,
be sure to replace all four tires. 2. All season tires
All season tires are designed to provide
better traction in snow and to be adequate
for driving in most winter conditions, as
well as for use all year round.
All season tires, however, do not have
adequate traction performance compared
with snow tires in heavy or loose snow.
Also, all season tires fall short in accel-
eration and handling performance
compared with summer tires in highway
driving.
CAUTION
Do not mix summer and all season
tires on your vehicle as this can
cause dangerous handling charac-
teristics, resulting in loss of con-
trol.
Do not use tire other than the
manufacture’s designated tires, and
never mix tires or wheels of the
sizes different from the originals.

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, etc.; 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
are 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.

c. Reinstall the filler cap.
d. Remove the filler cap again and look
at the fluid level. If the fluid is cold,
the level should be in the ”COLD”
range on the dipstick. 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 DEXRON
-II or -III
to bring the level within the range.
e. 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 cargo weight rating are given
in Part 8.
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.
Do not bleed or reduce tire pressure
after driving. It is normal for the tire
pressure to be higher after driving.
Never exceed the cargo weight rat-
ing. The luggage weight should be dis-
tributed evenly.
Be sure to reinstall the tire inflation
valve caps. Without the valve caps,
dirt or moisture could get into the valve
core and cause air leakage. If the caps
have been lost, have new ones put on
as soon as possible.

Checking and replacing tires
CHECKING YOUR TIRES
Check the tire tread for the tread wear
indicators. If the indicators show, re-
place the tires.
The tires on your Toyota have built-in
tread wear indicators to help you know
when the tires need replacement. When
the tread depth wears to 1.6 mm (0.06
in.) or less, the indicators will appear. If
you can see the indicators in two or more
adjacent grooves, the tire should be re-
placed. The lower the tread, the higher
the risk of skidding.
The effectiveness of snow tires is lost
if the tread wears down below 4 mm
(0.16 in.).
Check the tires regularly for damage
such as cuts, splits and cracks. If any
damage is found, consult with a techni-
cian and have the tire repaired or re-
placed.
Even if the damage does not appear seri-
ous, a qualified technician should examine
the damage. Objects which have pene-
trated the tire may have caused internal
damage.
Any tires which are over six years old
must be checked by a qualified techni-
cian even if damage is not obvious.
Tires deteriorate with age even if they
have never or seldom been used.
This also applies to the spare tire and
tires stored for future use.
REPLACING YOUR TIRES
When replacing a tire, use only the
same size and construction as original-
ly installed and with the same or great-
er load capacity.
Using any other size or type of tire may
seriously affect handling, ride, speedome-
ter/odometer calibration, ground clearance,
and clearance between the body and tires
or snow chains.
CAUTION

Do not mix radial, bias belted, or
bias-ply tires on your vehicle. It can
cause dangerous handling charac-
teristics, 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.

T100(U)185
Rotating tires
To equalize tire 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.
Installing snow tires and chains
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 rear 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
replacing.
