Vehicles with rear height control air
suspension: If you drive through
water, set the vehicle height to “HI”
with the height control switch and
then change to manual control
mode by pushing the height control
mode select switch. Do not exceed
30 km/h (18 mph) or “HI” mode will
automatically change to “N” mode.
Do not drive through water deeper
than about 700 mm (28 in.) even if
the vehicle height is in “HI” mode.When driving your vehicle off−road, please
observe the following precautions to en-
sure your driving enjoyment and to help
prevent the closure of areas to off −road
vehicles.
a. Drive your vehicle only in areas where off−road vehicles are permitted to trav-
el.
b. Respect private property. Get owner ’s permission before entering private prop-
erty.
c. Do not enter areas that are closed. Honor gates, barriers and signs that re-
strict travel.
d. Stay on established roads. When condi- tions are wet, driving techniques should
be changed or travel delayed to pre-
vent damage to roads.
For owners in U.S. mainland, Hawaii and
Puerto Rico:
To obtain additional information pertaining
to driving your vehicle off −road, consult

Make sure your coolant is properly pro-
tected against freezing.
Only use “Toyota Super Long Life Coolant”
or similar high quality ethylene glycol
based non−silicate, non −amine, non− nitrite,
and non− borate coolant with long −life
hybrid organic acid technology. (Coolant
with long −life hybrid organic acid
technology is a combination of low
phosphates and organic acids.)
See “Checking the engine coolant level”
on page 428 in Section 7 −2 for details of
coolant type selection.
For the U.S.A.—“Toyota Super Long Life
Coolant” is a mixture of 50% coolant and
50% deionized water. This coolant pro-
vides protection down to about −35 C
( − 31 F).
For Canada—“Toyota Super Long Life
Coolant” is a mixture of 55% coolant and
45% deionized water. This coolant pro-
vides protection down to about −42 C
( − 44 F).
NOTICE
Do not use plain water alone.
Check the condition of the battery and
cables.
Cold temperatures reduce the capacity of
any battery, so it must be in top shape
to provide enough power for winter start-
ing. Section 7 −3 tells you how to visually
inspect the battery. Your Toyota dealer
and most service stations will be pleased
to check the level of charge.
Make sure the engine oil viscosity is
suitable for the cold weather.
See page 426 in Sec t i on 7 −2 for recom-
mended viscosity. Leaving a heavy sum-
mer oil in your vehicle during winter
months may cause harder starting. If you
are not sure about which oil to use, call
your Toyota dealer—they will be pleased
to help.
Keep the door locks from freezing.
Squirt lock de −icer or glycerine into the
locks to keep them from freezing. Use a washer fluid containing an anti-
freeze solution.
This product is available at your Toyota
dealer and most auto parts stores. Follow
the manufacturer ’s directions for how
much to mix with water.
NOTICE
Do not use engine antifreeze or any
other substitute because it may dam-
age your vehicle’s paint.
Do not use your parking brake when
there is a possibility it could freeze.
When parking, put the transmission into
“P” and block the front wheels. Do not
use the parking brake, or snow or water
accumulated in and around the parking
brake mechanism may freeze, making it
hard to release.

CAUTION
If the total trailer weight exceeds
453 kg (1000 lb.), trailer brakes are
required.
Never tap into your vehicle’s hy-
draulic system as it would lower its
braking effectiveness.
Never tow a trailer without using a
safety chain securely attached to
both the trailer and the vehicle. If
damage occurs to the coupling unit
or hitch ball, there is danger of the
trailer wandering over into another
lane.
SERVICE CONNECTOR FOR TOWING
BRAKE CONTROLLER (with towing
package)
Your vehicle is equipped with a service
connector for the towing brake controller
as shown. Link the connector to the tow-
ing brake controller via the sub wire har-
ness stored in the glove box. The detailed
explanation of the sub wire harness circuit
is packed together with the sub wire har-
ness.
Be sure to position the towing brake con-
troller where it does not prevent the driver
from operating the pedal.
Toyota recommends that the sub wire har-
ness be stored in the glove box when it
is not in use.TIRES
Ensure that your vehicle’s tires are
properly inflated. See page 431 in Sec-
tion 7
−2 and page 460 in Section 8 for
instructions.
The trailer tires should be inflated to
the pressure recommended by the trail-
er manufacturer in respect to the total
trailer weight.

To avoid serious personal injury and
damage to your vehicle which might re-
sult from battery explosion, acid burns,
electrical burns, or damaged electronic
components, these instructions must be
followed precisely.
If you are unsure about how to follow this
procedure, we strongly recommend that
you seek the help of a competent me-
chanic or towing service.
CAUTION
Batteries contain sulfuric acid
which is poisonous and corrosive.
Wear protective safety glasses when
jump starting, and avoid spilling
acid on your skin, clothing, or ve-
hicle.
If you should accidentally get acid
on yourself or in your eyes, remove
any contaminated clothing and flush
the affected area with water imme-
diately. Then get immediate medical
attention. If possible, continue to
apply water with a sponge or cloth
while en route to the medical office.
The gas normally produced by a
battery will explode if a flame or
spark is brought near. Use only
standardized jumper cables and do
not smoke or light a match while
jump starting.
NOTICE
The battery used for boosting must
be 12 V. Do not jump start unless you
are sure that the booster battery is
correct.
JUMP STARTING PROCEDURE1. If the booster battery is installed in another vehicle, make sure the vehicles
are not touching. Turn off all unneces-
sary lights and accessories.
When boosting, use the battery of
matching or higher quality. Any other
battery may be difficult to jump start
with.
If jump starting is difficult, charge the
battery for several minutes.
2. If required, remove all the vent plugs from the booster and discharged batter-
ies. Lay a cloth over the open vents
on the batteries. (This helps reduce the
explosion hazard, personal injuries and
burns.)
3. If the engine in the vehicle with the booster battery is not running, start it
and let it run for a few minutes. During
jump starting run the engine at about
2000 rpm with the accelerator pedal
lightly depressed.

Adjust the air pressu re to the specifi-
cation designated on page 460 in
Section 8. If the pressure is lower,
drive slowly to the nearest service
station and fill to the correct pressure.
Do not forget to reinstall the tire infla-
tion valve cap as dirt and moisture
could get into th e 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.
With a spare tire of the same wheel
type as the installed tires—
As soon after changing wheels as
possible, tighten the wheel nuts to the
torque specified on page 460 in Sec-
tion 8 with a torque wrench. Have a
technician repair the flat tire. With a spare tire of different wheel
type from the installed tires—
As soon after changing wheels as
possible, tighten the wheel nuts to the
torque specified on page 460 in Sec-
tion 8 with a torque wrench. Have a
technician repair the flat tire and re-
place the spare tire with it.
Initial adjustment of the tire pres-
sure warning system is necessary
after you have replaced your tires
or wheels. See “Tire pressure
warning system” on page 198 in
Section 17.
CAUTION
Before driving, make sure all the
tools, jack and flat tire are se-
curely in place in their storage
location to reduce the possibility
of personal injury during a colli-
sion or sudden braking.
If your vehicle becomes stuck in snow,
mud, sand, etc., then you may attempt
to rock the vehicle free by moving it
forward and backward.
Twowheel drive models—Turn off the
traction control system to become un-
stuck to allow the tires to spin enough
to remove the vehicle from the obstruc-
tion. For details, see “Traction control
system” on page 182 in Section 17.
Fourwheel drive models—Lock the cen-
ter differential to become unstuck. For
details, see “Fourwheel drive system”
on page 177 in Section 17.
CAUTION
Do not attempt to rock the vehicle
free by moving it forward and back-
ward if people or objects are any-
where near the vehicle. During the
rocking operation the vehicle may
suddenly move forward or backward
as it becomes unstuck, causing injury
or damage to nearby people or ob-
jects.

If towing is necessary, we recom-
mended you have it done by your
Toyota dealer or a commercial tow
truck service. In consultation with them,
have your vehicle 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” on page 401 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.
CAUTION
Vehicles with rear height control air
suspension system: When your ve-
hicle is towed, set the vehicle height
to “N” in automatic control mode,
then select manual control mode by
pushing the height control mode se-
lect switch. Otherwise, the vehicle
height may change because of the
automatic leveling function, resulting
in an accident. For details, see “Rear
height control air suspension” on
page 189 in Section 17.
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 ignition key in the “ACC” posi-
tion.
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.
From rear—
We recommend using a towing dolly under
the front wheels. If you do not use a
towing dolly, place the ignition key in the
“ACC” position, put the transmission in
neutral and the transfer in “2WD” mode.
NOTICE
Do not tow with the key removed or
in the “LOCK” position when towing
from the rear without a towing dolly.
The steering lock mechanism is not
strong enough to hold the front
wheels straight.
(b) Using flat bed truck
(c) Towing with sling type truck
All models—
(c) Towing with sling type truck
NOTICE
Do not tow with sling type truck, ei-
ther from the front or rear. This may
cause body damage.
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 the emergency towing hook
under the front of the vehicle. Use ex-
treme caution when towing the vehicle.
NOTICE
Only use specified towing hook;
otherwise your vehicle may be dam-
aged.

403
CAUTION
If the emergency towing hook is used
to get out when your vehicle becomes
stuck in mud, sand or other condition
from which the vehicle cannot be
driven out under its own power, make
sure to observe the precautions men-
tioned below. Otherwise, excessive
stress will be put on the hook and
the towing cable or chain may break,
causing serious injury or damage.
If the towing vehicle can hardly
move, do not forcibly continue the
towing. Contact your Toyota dealer
or a commercial tow truck service
for assistance.
Tow the vehicle as straight ahead
as possible.
Keep away from the vehicle during
towing.
The following methods are effective to
get out when your vehicle is stuck in
mud, sand or other condition from
which the vehicle cannot be driven out
under its own power. Use extreme cau-
tion when towing vehicles. In addition,
keep away from the vehicles and towing
cable or chain when towing.
Remove the soil and sand in the front
and the back of the tires.
Place a stone or wood under the tires.You can purchase a new key at your
Toyota dealer if you can give them the
key number and master key.
Even if you lose only one key, contact
your Toyota dealer to make a new key. If
you lose all your master keys, you cannot
make new keys; the whole engine immobi-
lizer system must be replaced.
See the suggestion given in “Keys” on
page 14 in Section 1
−2.
If your keys are locked in the vehicle and
you cannot get a duplicate, many Toyota
dealers can still open the door for you,
using their special tools. If you must
break a window to get in, we suggest
breaking the smallest side window be-
cause it is the least expensive to replace.
Be extremely cautious to avoid cuts from
the glass.
