Scrapping of your Toyota
The SRS airbag and seat belt pretensioner devices in your
Toyota contain explosive chemicals. If the vehicle is
scrapped with the airbags and pretensioners left as they
are, this may cause an accident such as fire. Be sure to
have the systems of the SRS airbag and seat belt preten-
sioner removed and disposed of by a qualified service
shop or by your Toyota dealer before you dispose of your
vehicle.
Onpavement and offroad
driving tips
This vehicle will handle and maneuver differently from an
ordinary passenger car because it is also designed for
off−road use. It has a significantly higher rollover rate than
other types of vehicles. In addition, this vehicle has a
higher ground clearance and center of gravity than that of
an ordinary passenger car. This vehicle design feature
causes this type of vehicle to be more likely to rollover.
Failure to operate this vehicle correctly may result in loss
of control, accidents or vehicle rollover causing death or
serious injury. Be sure to read “Off −road vehicle
precautions” on page 442 in Section 2 and “Off −road
driving precautions” on page 478 in Section 3.

This vehicle has higher ground clear-
ance and narrower tread in relation to
the height of its center of gravity to
make it capable of performing in a wide
variety of offroad applications. Specific
design characteristics give it a higher
center of gravity than ordinary passen-
ger cars. This vehicle design feature
causes this type of vehicle to be more
likely to rollover. And, it has a signifi-
cantly higher rollover rate than other
types of vehicles. An advantage of the
higher ground clearance is a better
view of the road allowing you to antici-
pate problems. It is not designed for
cornering at the same speeds as ordi-
nary passenger cars any more than
lowslung sports cars are designed to
perform satisfactorily under offroad
conditions. Therefore, sharp turns at
excessive speeds may cause rollover.CAUTION
Always observe the following precau-
tions to minimize the risk of serious
personal injury or damage to your ve-
hicle:
In a rollover crash, an unbelted per-
son is significantly more likely to
die than a person wearing a seat
belt. Therefore, the driver and all
passengers should fasten their seat
belts whenever the vehicle is mov-
ing.
Avoid sharp turns or abrupt maneu-
vers, if at all possible. Failure to
operate this vehicle correctly may
result in loss of control or vehicle
rollover causing death or serious
injury.
Avoid loading any items on the roof
that will raise the vehicle’s center
of gravity.
Always slow down in gusty cross-
winds. Because of its profile and
higher center of gravity, your ve-
hicle is more sensitive to side
winds than an ordinary passenger
car. Slowing down will allow you to
have much better control.

5. After making sure that no one is in the vehicle, as the jack
touches the vehicle and begins
to lift, doublecheck that it is
properly positioned.
Rear side only—
When positioning the jack under the
rear axle housing, make sure the
groove on the top of the jack fits with
the rear axle housing.

6. After making sure that no one is in the vehicle, raise it high
enough so that the temporary
spare tire can be installed.
Remember you will need more ground
clearance when putting on the tempo-
rary spare tire than when removing
the flat tire.

Twowheel drive models—
(a) Towing with wheel lift type truck
From front—
Use a towing dolly under the rear wheels.
NOTICE
Never tow a vehicle from the front
with the rear wheels on the ground,
as this may cause serious damage to
the transmission.
From rear—Place the engine switch in the
“ACC” position.
NOTICE
 When lifting wheels, take care to
ensure adequate ground clearance
for towing at the opposite end of
the raised vehicle. Otherwise, the
bumper and/or underbody of the
towed vehicle will be damaged dur-
ing towing.
 Do not tow with the key removed or
in the “LOCK” position, as the
steering lock mechanism is not
strong enough to hold the front
wheels straight while towing.
(b) Using flat bed truck Fourwheel drive models—
(a) Towing with wheel lift type truck
From front—
Use a towing dolly under the rear wheels.
NOTICE
Never tow a vehicle from the front
with the rear wheels on the ground,
as this may cause serious damage to
the transmission.

REPLACING YOUR TIRES
When replacing a tire, use a tire of
the same size and construction,
and the same or greater maximum
load as the originally installed
tires. Also, on fourwheel drive
models, all the tires must be the
same brand and have the same
tread patterns.
Using any other size or type of tire
may seriously affect handling, ride,
speedometer/odometer calibration,
ground clearance, and clearance be-
tween the body and tires or snow
chains.
Check that the maximum load of the
replaced tire is greater than 1/2 of the
Gross Axle Weight Ratings (GAWR)
of either the front axle or the rear
axle, whichever is greater. As for the
maximum load of the tire, see the load
limit at maximum cold tire inflation
pressure mentioned on the sidewall
of the tire, and as for the Gross Axle
Weight Ratings (GAWR), see the Cer-
tification Label. For details about the sidewall of the
tire and the Certification Label, see
“Tire information” on page 457 in
S ec t ion 2 and “Your Toy ot a’s
identification” on page 455 in Section
2.
CAUTION
Observe the following instruc-
tions. Otherwise, an accident
may occur resulting in death or
serious injuries.

Do not mix radial, bias belted,
or biasply tires on your ve-
hicle, as this may cause dan-
gerous handling characteris-
tics resulting in loss of control.
 Do not use tires other than the
manufacturer’s recommended
size, as this may cause danger-
ous handling characteristics
resulting in loss of control.
Do not use tires of different
brands, sizes and construc-
tions. This may damage the
drive system and prevent the
vehicle stability control system
from functioning correctly.
 Fourwheel drive models:
Do not use tires of different
brands, sizes, construction or
tread patterns, as this may
cause dangerous handling
characteristics resulting in
loss of control.
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” on page
503 in Section 4 for tire change proce-
dure.
When a tire is replaced, the wheel
should always be balanced.

As you might have difficulty in
identifying a flat or deflated tire, a tire
pressure warning system is provided on
this vehicle.
When replacing the wheels, be sure to
install tire pressure warning valves and
transmitters on the wheels. Consult your
Toyota dealer about how to set up the tire
pressure warning valves and transmitters.
CAUTION
Have the tires, wheels or tire pres-
sure warning valves and transmit-
ters replaced and ID codes regis-
tered by Toyota dealer. If you need
tire pressure warning valves and
transmitters, purchase from Toyota
dealer.
The tire pressure warning valve and
transmitter nuts should always be
tightened to a torque of 4 N·m (0.4
kgf·m, 2.9 ft·lbf).
The use of nongenuine wheels may
result in the tire pressure warning
system failure or airleak.
WHEN TO REPLACE YOUR WHEELS
If you have wheel damage such as
bending, cracks or heavy corrosion, the
wheel should be replaced.
If you fail to replace a damaged wheel,
the tire may slip off the wheel or cause
loss of handling control.
WHEEL SELECTION
When replacing wheels, care should be
taken to ensure that the wheels are re-
placed by ones with the same load ca-
pacity, diameter, rim width, and offset.
Correct replacement wheels are available
at your Toyota dealer.
A wheel of a different size or type may
adversely affect handling, wheel and bear-
ing life, brake cooling, speedometer/odom-
eter calibration, stopping ability, headlight
aim, bumper height, vehicle ground clear-
ance, and tire or snow chain clearance to
the body and chassis. Replacement with used wheels is not rec-
ommended as they may have been sub-
jected to rough treatment or high mileage
and could fail without warning. Also, bent
wheels which have been straightened may
have structural damage and therefore
should not be used. Never use an inner
tube in a leaking wheel which is designed
for a tubeless tire.
CAUTION
Observe the following instructions.
Otherwise, an accident may occur re-
sulting in death or serious injuries.
Do not use wheels other than the
manufacturer ’s recommended size,
as this may cause dangerous han-
dling characteristics resulting in
loss of control.
Fourwheel drive models:
Do not use wheels of different
brands, sizes and types, as this
may cause dangerous handling
characteristics resulting in loss of
control.
