curely. (See ºFuel tank capº in Chapter
1- 2 for instructions.)
c. There is a problem somewhere in your
engine or automatic transmission electrical
system.
If it comes on while you are driving in
case c, have your vehicle checked/re-
paired by your Toyota dealer as soon as
possible.
(g) Low Fuel Level Warning Light
This light comes on when the fuel level
in the tank becomes nearly empty. Fill up

key is turned to the ºONº position. After
a few seconds, the light will go off.
When the ºABSº warning light is on (and

pretensioner are operating properly.
The warning light system monitors the air-
bag sensor assembly, front airbag sen-
sors, seat belt pretensioner assemblies,
inflators, warning light, interconnecting wir-
ing and power sources.
If either of the following conditions occurs,
this indicates a malfunction somewhere in
the parts monitored by the warning light
system. Contact your Toyota dealer as
soon as possible to service the vehicle.

Avoid high speeds on wet roads. The
anti- lock brake system cannot elimi-
nate the risk of hydroplaning and loss
of tire friction.
Always maintain a safe distance from the
vehicle in front of you. Compared with
vehicles not fitted with an anti- lock brake
system, your vehicle may r equire a longer
stopping distance in the following cases:
Driving on rough, gravel or snow- cov-
ered roads.
Driving with tire chains installed.
Driving on roads where the road sur-
face is pitted or has other differences
in surface height.
CAUTION
Do not use tires other than the
manufacturer 's designated tires, and
do not mix tires or wheels of differ-
ent sizes. You may prevent the anti-
lock brake system from operating at
full effectiveness.
Vehicles with rear differential lock sys-
tem 'The anti- lock brake system does not
operate when the rear differential is
locked. It is normal operation for the
ºABSº warning light to be on at this time.

Off- road driving precautions
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 travel.
b. Respect private property. Get owner 's
permission before entering private proper-
ty.
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 prevent
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
the following organizations.
State and Local Parks and Recreation
Departments
State Motor Vehicle Bureau
Recreational Vehicle Clubs
U.S. Forest Service and Bureau of
Land Management
CAUTION
Always observe the following precau-
tions to minimize the risk of serious
personal injury or damage to your ve-
hicle: Drive carefully when off the road.
Do not take unnecessary risks by
driving in dangerous places.
Do not grip the steering wheel
spokes when driving off- road. A
bad bump could jerk the wheel and
injure your hands. Keep both hands
and especially your thumbs on the
outside of the rim.
Always check your brakes for effec-
tiveness immediately after driving in
sand, mud, water or snow.
After driving through tall grass,
mud, rock, sand, rivers, etc., check
that there is no grass, bush, paper,
rags, stone, sand, etc. adhering or
trapped on the underbody. Clear off
any such matter from the under-
body. If the vehicle is used with
these materials trapped or adhering
to the underbody, a breakdown or
fire could occur.
The driver and all passengers
should fasten their seat belts whe-
never the vehicle is moving.
NOTICE
If driving through water, such as
when crossing shallow streams,first check the depth of the waterand the bottom of the river bed for
firmness. Drive slowly and avoiddeep water.
Take all necessary safety measures
to ensure that water damage to theengine or other components doesnot occur.
Water entering the engine air intakewill cause severe engine damage.
Water can wash the grease fromwheel 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 brakediscs may affect braking efficiency and may damage brake system com-
ponents.
Always perform a maintenance in-spection after each day of off- road
driving that has taken you throughrough terrain, sand, mud, or water.For scheduled maintenance informa-
tion, refer to the separate ºSched-uled Maintenance Guideº or ºOwn-er 's Manual Supplementº.
Winter driving tips
Make sure you have a proper freeze
protection of engine coolant.
Your coolant must contain ethylene- glycol
type coolant for a proper corrosion
protection of aluminum components. Use
ºToyota Long Life Coolantº or equivalent.
See Chapter 7- 2 for details about coolant
type selection.
NOTICE
Do not use alcohol type antifreeze or
plain water alone.
When it is extremely cold, we recommend
to use 60% solution for your Toyota, to
provide protection down to about -50 5C
(- 58 5F). Do not use more than 70% solu-
tion for better coolant performance.
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. Chapter 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 Chapter 7- 2 for recommended viscos-
ity. Leaving a heavy summer oil in your
vehicle during winter months may cause
harder starting. If you are not sure about
which oil to use, call your Toyota dealerÐ
he 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.

(b) Starting a flooded engine
If the engine will not start, your engine
may be flooded because of repeated
cranking.
If this happens, turn the key to ºSTARTº
with the accelerator pedal held down.
Keep the key and accelerator pedal so for
15 seconds and release them. Then try
starting the engine with your foot off the
accelerator pedal.
If the engine does not start after 15 se-
conds of cranking, release the key, wait
a few minutes and try again.
If the engine still will not start, it needs
adjustment or repair. Call a Toyota dealer
or qualified repair shop for assistance.
NOTICE
Do not crank for more than 30 se-
conds at a time. This may overheatthe starter and wiring systems.
(c) Jump starting
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 youare sure that the booster battery is correct.
