Advice for driving on slippery roads in
“L4” (low speed position) mode
If the multi −mode control switch knob is
in the “L4” and the automatic transmission
selector lever is in the “2” when you drive
in steep off −road areas, the output of the
brake can be controlled effectively by the
active traction control system, which as-
sists the driver to control the driving pow-
er of 4 wheels.
Use the “L” position of the automatic
transmission selector lever for maximum
power and traction when your wheels get
stuck or when you drive down a steep
incline. In the following cases, the output
of the brake can be controlled by the
active traction control system if the engine
speed is under 3000 rpm (normally engine
speed is under 3000 rpm when the wheels
get unstuck).
The multi −mode control switch knob in
the “L4” position and the automatic
transmission selector lever in the “L”
position
The multi −mode control switch knob in
the “L4” position and the automatic
transmission selector lever in the “D”,
“3” or “2” with the transmission down-
shifting to first gear
The multi −mode control switch knob in
the “L4” position and the automatic
transmission selector lever in the “R”
position
(As for the automatic transmission selec-
tor lever positions, see “Automatic trans-
mission (4 −speed)” on page 154 in this
Section.) The A.D.D. can be engaged or disen-
gaged by the shifting operations de-
scribed in “(c) Shifting procedure”.
You should drive in four
−wheel drive for
at least 16 km (10 miles) each month.
This will assure that the front drive com-
ponents are lubricated.

If the vehicle is going to skid during driv-
ing, the slip indicator light blinks and an
alarm sounds intermittently. Special care
should be taken while driving.
The slip indicator light comes on for a few
seconds when the ignition key is turned
to “ON”. If the indicator light does not
come on when the ignition is turned on,
contact your Toyota dealer.Fourwheel drive models only—
Pushing the center differential lock
switch automatically turns the vehicle
stability control system off. At this
time, the “VSC OFF” indicator comes
on with the center differential lock indi-
cator light.
The “VSC OFF” indicator light comes on
for a few seconds when the ignition key
is turned to “ON”. It will come on again
when you push the center differential lock
switch to turn off the system. In the following cases, contact your Toyota
dealer:
The indicator light does not come on
when the ignition key is turned to
“ON”.
The indicator light remains on after the
ignition key is turned to “ON”.
The indicator light comes on when the
system is on while driving.
NOTICE
Make sure that the center differential
lock indicator light goes off before
normal driving.

The brake pad wear limit indicators on
your disc brakes give a warning noise
when the brake pads are worn to where
replacement is required.
If you hear a squealing or scraping noise
while driving, have the brake pads
checked and replaced by your Toyota
dealer as soon as possible. Expensive ro-
tor damage can result if the pads are not
replaced when necessary. Your Toyota is equipped with a limited
−slip
center differential (transfer). If one wheel
begins to spin, the limited −slip center dif-
ferential (transfer) is designed to aid trac-
tion by automatically transmitting driving
force to the wheels on the other drive
axle. It transmits driving force to the front
wheels if a rear wheel spins, and to the
rear wheels if a front wheel spins.
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
brand, size, construction and load ca-
pacity as the original tires on your
Toyota because damage to the limit-
edslip differential could possibly oc-
cur 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.

NOTICE
If driving through water, such as
when crossing shallow streams,
first check the depth of the water
and the bottom of the river bed for
firmness. Drive slowly and avoid
deep water.
 Take all necessary safety measures
to ensure that water damage to the
engine or other components does
not occur.
Water entering the engine air intake
will cause severe engine damage.
Water can wash the grease from
wheel bearings, causing rusting and
premature failure, and may also en-
ter the differentials, transmission
and transfer case, reducing the gear
oil’s lubricating qualities.
 Sand and mud that has accumulated
in brake drums and around brake
discs may affect braking efficiency
and may damage brake system com-
ponents.
Always perform a maintenance in-
spection after each day of offroad
driving that has taken you through
rough terrain, sand, mud, or water.
For scheduled maintenance informa-
tion, refer to the “Scheduled Main-
tenance Guide” or “Owner’s Manual
Supplement”.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 hy-
brid organic acid technology.
See “Checking the engine coolant level”
on page 362 in Section 7 −2 for details of
coolant type selection.
“Toyota Super Long Life Coolant” is pre −
mixed with 50% coolant and 50% deion-
ized water. This coolant provides protec-
tion down to about −35 C ( −31 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.

NOTICE
Only use specified towing eyelet;
otherwise your vehicle may be dam-
aged.
 Never tow a vehicle from the rear
with four wheels on the ground.
This may cause serious damage to
the transmission.
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 ve-
hicles. Avoid sudden starts or erratic
driving maneuvers which would place
excessive stress on the emergency
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 “N”. The key
must be in “ACC” (engine off) or “ON”
(engine running).
Four −wheel drive models—On multi −mode
four −wheel drive models, put the multi −
mode control switch knob in “H2”. On full −
time four −wheel drive models, unlock the
center differential.
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.
Before emergency towing, check that
the eyelet is not broken or damaged
and that the installation bolts are not
loose.
Fasten the towing cable or chain se-
curely to the eyelet.
Do not jerk the eyelet. Apply steady
and even force.
To avoid damaging the eyelet, do not
pull from the side or at a vertical
angle. Always pull straight ahead.
