Injured person. Toyota recommends the
use of a seat belt. Depending on the inju-
ry, first check with your doctor for specific
recommendations.
CAUTION
Persons should ride in their seats
properly wearing their seat belts
whenever the vehicle is moving.
Otherwise, they are much more likely
to suffer serious bodily injury or
death in the event of sudden braking
or a collision.
When using the seat belts, observe
the following:
Use the belt for only one person at
a time. Do not use a single belt for
two or more people—even children.
Avoid reclining the seatbacks too
much. The seat belts provide maxi-
mum protection when the seatbacks
are in the upright position. (Refer
to the seat adjustment instructions.)
Be careful not to damage the belt
webbing or hardware. Take care that
they do not get caught or pinched
in the seat or side doors.
Inspect the belt system periodically.
Check for cuts, fraying, and loose
parts. Damaged parts should be re-
placed. Do not disassemble or
modify the system.
Keep the belts clean and dry. If
they need cleaning, use a mild soap
solution or lukewarm water. Never
use bleach, dye, or abrasive clean-
ers—they may severely weaken the
belts. (See “Cleaning the interior”
in Section 5.)
Replace the belt assembly (includ-
ing bolts) if it has been used in a
severe impact. The entire assembly
should be replaced even if damage
is not obvious.Adjust the seat as needed (front seats
only) and sit up straight and well back
in the seat. To fasten your belt, pull it
out of the retractor and insert the tab
into the buckle.
You will hear a click when the tab locks
into the buckle.
The seat belt length automatically adjusts
to your size and the seat position.
The retractor will lock the belt during a
sudden stop or on impact. It also may
lock if you lean forward too quickly. A
slow, easy motion will allow the belt to
extend, and you can move around freely.

Antilock brake system is not de-
signed to shorten the stopping dis-
tance: Always drive at a moderate
speed and maintain a safe distance
from the vehicle in front of you.
Compared with vehicles without an
antilock brake system, your vehicle
may require a longer stopping dis-
tance in the following cases:
Driving on rough, gravel or snow
covered roads.
Driving with tire chains installed.
Driving over the steps such as the
joints on the road.
Driving on roads where the road
surface is pitted or has other differ-
ences in surface height.
Install all 4 tires of specified size at
appropriate pressure: The antilock
brake system detects vehicle speeds
using the speed sensors for respec-
tive wheels’ turning speeds. The use
of tires other than specified may fail
to detect the accurate turning speed
resulting in a longer stopping dis-
tance.

“ABS” Warning light
The light comes on when the ignition key
is turned to the “ON” position. If the anti −
lock brake system works properly, the
light turns off after a few seconds. There-
after, if the system malfunctions, the light
comes on again.
When the “ABS” warning light is on (and
the brake system warning light is off), the
anti −lock brake system does not operate,
but the brake system still operates con-
ventionally.
When the “ABS” warning light is on (and
the brake system warning light is off), the
anti −lock brake system does not operate
so that the wheels could lock up during
a sudden braking or braking on slippery
road surfaces.
If either of the following conditions oc-
curs, this indicates a malfunction some-
where in the components monitored by
the warning light system. 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 “ON” posi-
tion, or remains on.
The light comes on while you are driv-
ing.

The side step is for easier stepup
loading.
CAUTION
For models equipped with a StepSide
bed:
Do not allow more than one person
to get on the side step. Do not
exceed the maximum weight limit of
136 kg (300 lb.) on the side step.
Never drive the vehicle with anyone
on the side steps.
Do not stand on the side steps
while the vehicle is moving.
Some Toyotas are equipped with a lim-
ited−slip differential. If one of the rear
wheels begins to spin, the limited −slip dif-
ferential is designed to aid traction by
automatically transmitting driving force to
the other rear wheel. If you are not sure
whether your vehicle is equipped with one,
you can ask your Toyota dealer.
CAUTION
Do not start or run the engine while
your vehicle is supported by a jack.
The vehicle could be driven off the
jack and could pose a danger or re-
sult in serious injury.
NOTICE
Use only a spare tire of the same
size, construction and load capacity
as the original tires on your Toyota
because damage to the limitedslip
differential could possibly occur with
another tire type.
The vehicle identification number (VIN)
is the legal identifier for your vehicle.
This number is on the left top of the
instrument panel, and can be seen
through the windshield from outside.
This is the primary identification number
for your Toyota. It is used in registering
the ownership of your vehicle.

7. “TUBELESS” or “TUBE
TYPE”— A tubeless tire does not
have a tube inside the tire and air
is directly filled in the tire. A tube
type tire has a tube inside the tire
and the tube maintains the air
pressure.

see “Checking and replacing tires”
in Section 7 −2.
9. Maximum cold tire inflation pressure— This means the pres-
sure to which a tire may be in-
flated. For details about recom-
mended cold tire inflation
pressure, see “Tires” in Section 8. 10.Summer tire or all season
tire— An all season tire has “M+S”
on the sidewall. The tire not
marked with “M+S” is a summer
tire. For details, see “Types of
tires” in this Section.

Vehicle load limits include total load
capacity, seating capacity, towing ca-
pacity and cargo capacity. Follow the
load limits shown below.
Total load capacity (pay load)
Total load capacity means combined
weight of occupants, cargo and lug-
gage. Tongue load is included when
trailer towing. For the total load ca-
pacity about your vehicle, see “Pay-
load” in Section 8.
Seating capacity:
Single cab modelsTot al 3
Access cab models Models with front bench seat: To-
tal 6 (Front 3, Rear 3)
Models with front separate seat:
Total 5 (Front 2, Rear 3)
Seating capacity means the maxi-
mum number of occupants whose
weight is supposed to be 68 kg (150
lb.) per person. Depending on the
weight of person, the seating ca-
pacity given may exceed the total
load capacity. NOTICE
Even if the number of occupants
are within the seating capacity,
do not exceed the total load ca-
pacity.
Towing capacity
Towing capacity means the maximum
gross trailer weight (trailer weight plus
its cargo weight) that your vehicle is
able to tow. For the towing capacity
about your vehicle, see “Towing ca-
pacity” in Section 8.
Cargo capacity
Cargo capacity may increase or de-
crease depending on the size (weight)
and the number of occupants. For de-
tails, see “Capacity and distribution”
that follows.
CAUTION
Do not apply the load more than
each load limit. That may cause
not only damage to the tires, but
also deterioration to the steering
ability and braking ability, caus-
ing an accident.
