Fourwheel drive models
If towing is necessary, we recommend
you have it done by your Toyota dealer
or a commercial tow truck service. In
consultation with them, have your ve-
hicle towed using either (a) or (b).
Only when you cannot receive a towing
service from a Toyota dealer or com-
mercial tow truck service, tow your ve-
hicle carefully in accordance with the
instructions given in “—Emergency tow-
ing” in this Section.
Proper equipment will help ensure that
your vehicle is not damaged while being
towed. Commercial operators are generally
aware of the state/provincial and local
laws pertaining to towing.
Your vehicle can be damaged if it is
towed incorrectly. Although most operators
know the correct procedure, it is possible
to make a mistake. To avoid damage to
your vehicle, make sure the following pre-
cautions are observed. If necessary, show
this page to the tow truck driver.
TOWING PRECAUTIONS:
Use a safety chain system for all towing,
and abide by the state/provincial and local
laws. The wheels and axle on the ground
must be in good condition. If they are
damaged, use a towing dolly. Twowheel drive models—
(a) Towing with wheel lift type truck

Manual transmission:
We recommend using a towing dolly under
the rear wheels. If you do not use a tow-
ing dolly, release the parking brake and
put the transmission in neutral.
Automatic transmission:
Use a towing dolly under the rear wheels.
NOTICE
Never tow a vehicle with an automatic
transmission from the front with the
rear wheels on the ground, as this
may cause serious damage to the
transmission.

If towing is necessary, we recommend
you to have it done by your Toyota
dealer or a commercial tow truck ser-
vice.
If towing service is not available in an
emergency, your vehicle may be tempo-
rarily towed by a cable or chain se-
cured to one of the emergency towing
eyelets under the front of the vehicle.
Use extreme caution when towing the
vehicle.
NOTICE
Only use specified towing eyelet;
otherwise your vehicle may be dam-
aged.
A driver must be in the vehicle to steer
it and operate the brakes.
Towing in this manner may be done only
on hard−surfaced roads for a short dis-
tance and at low speeds. Also, the
wheels, axles, drive train, steering and
brakes must all be in good condition.
CAUTION
Use extreme caution when towing the
vehicle. Avoid sudden starts or errat-
ic driving maneuvers which would
place excessive stress on the emer-
gency towing eyelet and towing cable
or chain. The eyelet and towing cable
or chain may break and cause serious
injury or damage.
NOTICE
Use only a cable or chain specifically
intended for use in towing vehicles.
Securely fasten the cable or chain to
the towing eyelet provided.
Before towing, release the parking brake
and put the transmission in neutral (manu-
al) or “N” (automatic). The key must be
in “ACC” (engine off) or “ON” (engine run-
ning).
CAUTION
If the engine is not running, the pow-
er assist for the brakes and steering
will not work so steering and braking
will be much harder than usual.

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 side wall of the
tire and the Certification Label.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.
 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.
For vehicles with vehicle stability
control system—
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.
Toyota recommends all four tires,
or at least both of the front or rear
tires be replaced at a time as a set.
S ee “I f you hav e a fl at tire” in Section
4 for tire change procedure.
When a tire is replaced, the wheel
should always be balanced.
An unbalanced wheel may affect ve-
hicle 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 repl aced
w i t h a new on e.

To equalize the wear and help ex-
tend tire life, Toyota recommends
that you rotate your tires accord-
ing to the maintenance schedule.
(For scheduled maintenance infor-
mation, please refer to the “Sched-
uled Maintenance Guide” or “Own-
er’s Manual Supplement”.)
However, the most appropriate tim-
ing for tire rotation may vary ac-
cording to your driving habits and
road surface conditions.
See “If you have a flat tire” in Section
4 for tire change procedure.
When rotating tires, check for uneven
wear and damage. Abnormal wear is
usually caused by incorrect tire pres-
sure, improper wheel alignment, out −
of −balance wheels, or severe braking.
Initial adjustment of the tire pres-
sure warning system is necessary
after you have rotated your tires.
See “Tire pressure warning sys-
tem” in Section 17.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 tires of
the same size, construction and load
capacity as the originally installed tires.
Also, on fourwheel drive models, all
the tires must be the same brand and
have the same tread patterns.
Do not use tires other than those men-
tioned above. Do not install studded tires
without first checking local regulations for
possible restrictions.CAUTION
Observe the following instructions.
Otherwise, an accident may occur re-
sulting in death or serious injuries.
Do not use snow tires other than
the manufacturer ’s recommended si-
ze, as this may cause dangerous
handling characteristics resulting in
loss of control.
Fourwheel drive models:
Do not use snow tires of different
brands, sizes, construction or tread
patterns, as this may cause danger-
ous handling characteristics result-
ing in loss of control.
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.

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.
When installing aluminum wheels,
check that the wheel nuts are tight
after driving your vehicle the first 1600
km (1000 miles).
If you have rotated, repaired, or
changed your tires, check that the
wheel nuts are still tight after driving
1600 km (1000 miles).
When using tire chains, be careful not
to damage the aluminum wheels.
Use only Toyota wheel nuts and
wrench designed for your aluminum
wheels.
When balancing your wheels, use only
Toyota balance weights or equivalent
and a plastic or rubber hammer.
As with any wheel, periodically check
your aluminum wheels for damage. If
damaged, replace immediately.
