124When driving your vehicle off-road,
please observe the following precautions
to ensure 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
property.
c. Do not enter areas that are closed.
Honor gates, barriers and signs that
restrict travel.
d. Stay on established roads. When con-
ditions 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
precautions to minimize the risk of
serious personal injury or damage
to your vehicle: 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 ef-
fectiveness immediately after driv-
ing 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 un-
derbody. If the vehicle is used with
these materials trapped or adher-
ing to the underbody, a breakdown
or fire could occur.! The driver and all passengers
should fasten their seat belts
whenever the vehicle is moving.
Off-road driving precautions (four-wheel drive models only)

125

If driving through water, such as
when crossing shallow streams,
first check the depth of the waterand the bottom of the river bed forfirmness. Drive slowly and avoid
deep water.
Take all necessary safety measuresto ensure that damage to the en-
gine or o ther components does not
occur.
Water entering the engine air intake
will cause severe engine damage.
Water can wash the grease fromwheel bearings, causing rustingand premature failure, and mayalso enter the differential,
transmission and transfer case, reducing the gear oil's lubricatingqualities.
Sand and mud that has accumu-lated in brake drums and around
brake discs may affect braking effi-
ciency and may damage brake sys-tem components.
NOTICEAlways perform a maintenance in-spection after each day of off-
road driving that has taken you through rough terrain, sand, mud,
or water. For scheduled mainte-
nance information, refer to theseparate Owner's Manual Sup-plement/Maintenance Scheduleº.Make sure you have ethylene-glycol
antifreeze in the radiator.
Do not use alcohol type antifreeze.
NOTICE
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 starting.Chapter 7-3 tells you how to visually in-
spect the battery. Your Toyota dealer and
most service stations will be pleased tocheck the level of charge.
Make sure the engine oil viscosity is
suitable for the cold weather.
See Chapter 7-2 for recommended vis-
cosity. 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 dealer- 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. To open
a frozen lock, try heating the key before in-serting it.
Winter driving tips

134If the engine will not start, your engine
may be flooded because of repeated cranking.
Turn the key to STARTº with the acceler-
ator 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 sec-
onds of cranking, release the key, wait afew minutes and try again.
If the engine still will not start, it needs ad-
justment or repair. Call a Toyota dealer or
qualified repair shop for assistance.
NOTICE
Do not crank for more than 30 sec- onds at a time. This may overheat
the starter and wiring systems.
To avoid serious personal injury and
damage to your vehicle which might
result from battery explosion, acid
burns, electrical burns, or damaged
electronic components, these instruc-
tions 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.
Batteries contain sulfuric acid
which is poisonous and corrosive.
Wear protective safety glasses
when jump starting, and avoid
spilling acid on your skin, cloth-
ing, or vehicle.
If you should accidentally get acid
on yourself or in your eyes, re- move any contaminated clothing
and flush the affected area with water for at least 15 minutes. Then
get immediate medical attention. If
possible, continue to apply water
with a sponge or cloth while en
route to the medical office. CAUTION
!

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 batteryis correct.
JUMP STARTING PROCEDURE
1. If the booster battery is installed in another vehicle, make sure the ve-
hicles are not touching. T urn off all un-
necessary lights and accessories.
2. If required, remove all the vent plugs from the booster and discharged bat-
teries. Lay a cloth over the open vents
on the batteries. (This helps reduce
the explosion hazard, personal injuries
and burns.)
(b) Starting a flooded engine (c) Jump starting

11. Check the air pressure of the
replaced tire.
Adjust the air pressure to the specification
designated in Part 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 inflation valve cap as dirt and moisture could get into the 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.
Xtra-cab models-After fixing the jack, put
the tool bag over the jack and fasten the tool bag with rubber bands shown in the il-
lustration.
As soon as possible after changing
wheels, tighten the wheel nuts to the torque specified in Part 8 with a torque
wrench and have a technician repair the
flat tire.
Before driving, make sure all the
tools, jack and flat tire are securely in place in their storage location to
reduce the possibility of personal
injury during a collision or suddenbraking. CAUTION

If towing is necessary, we recommend
you to have it done by your Toyota
dealer or a commercial tow truck ser-
vice. In consultation with them, have
your vehicle towed using either (a) or (b).
Only when you cannot receive a tow-
ing service from a Toyota dealer or
commercial tow truck service, tow
your vehicle carefully in accordance
with the instructions given in
ÐEmergency towingº in this part. Proper equipment will help ensure that your vehicle is not damaged while being
towed. Commercial operators are gener-
ally 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 few
precautions 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.
If your vehicle needs to be towedÐ

148From

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
vehicles. 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.

maintenance, as well as day-to-day
care, is more important than ever before
to ensure smooth, trouble-free, safe, and
economical drivings.
It is the owner's responsibility to make sure
the specified maintenance, including
general maintenance service, is per-
formed. Note that both the new vehicle
and emission control system warranties
specify that proper maintenance and care
must be performed. See Owner's Guide,
Owner 's Manual Supplement or W arranty

day-to-day care practices that are impor-
tant to your vehicle for proper operation.
It is the owner's responsibility to insure that the general maintenance items are
performed regularly.
These checks or inspections can be done
either by yourself or a qualified technician,
or if you prefer, your Toyota dealer will be
pleased to do them at a nominal cost. Scheduled maintenance
The scheduled maintenance items listed
in the Owner's Manual Supplement/
