CAUTION!
When driving off-road or in rugged
terrain, do not drive at excessive
speeds, jump the vehicle, or strike
objects, etc. This may cause loss of
control or vehicle rollover. You are
also risking expensive damage to
your vehicle's suspension and chassis. Drive gently and avoid high speeds.
Your vehicle does not need an elaborate
break-in. But following a few simple tips
for the first 1600 km (1000 miles) can add
to the future economy and long life of your vehicle:
Do not drive over 88 km/h (55 mph).
Run the engine at moderate speed be- tween 2000 and 4000 rpm.
Avoid full-throttle starts.
Try to avoid hard stops during the first
300 km (200 miles).
Do not drive slowly with the manual
transmission in a high gear.
Do not drive for a long time at any
single speed, either fast or slow.
Do not tow a trailer during the first 800
km (500 miles) FUEL TYPE
Your new vehicle must use only un-
leaded gasoline.
To help prevent gas station mixups, your
Toyota has a new smaller fuel tank opening.
The special nozzle on pumps with unleaded
fuel will fit it, but the larger standard nozzle
on pumps with leaded gas will not.
Do not use leaded gasoline. Use of
leaded gasoline will cause the
three-way catalytic converter tolose its effectiveness and the emis- sion control system to function im-properly. Also, this can increase maintenance costs.
NOTICE
OCTANE NUMBER
Select Research Octane Number 91 (Oc-
tane Rating 87) or higer.
Use of unleaded fuel with an octane num- ber or rating lower than stated above will
cause persistant heavy knocking. If se-
vere, this will lead to engine damage.
Break-in period Fuel

153
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. 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.
Do not use engine antifreeze or any
other substitute because it may
damage your vehicle's paint.
NOTICE
Do not use your parking brake when there is a possibility it could freeze. When parking, put the transmission into
Pº (automatic) or into first or reverse
(manual) and block the rear wheels. Do
not use the parking brake, or snow or wa-
ter accumulated in and around the parkingbrake mechanism may freeze, making it
hard to release. Keep ice and snow from accumulating
under the fenders.
Ice and snow built up under your fenders
can make steering difficult. During bad winter driving, stop and check under the
fenders occasionally. Depending on where you are driving,
we recommend you carry some emer- gency equipment.
Some of
the things you might put in the ve-
hicle are tire chains, window scraper, bag of sand or salt, flares, small shovel, jump- er cables, etc.

Part 4If your vehicle will not startÐ
(a) Simple checks
161
IN CASE OF AN EMERGENCY
If your vehicle will not start
If your engine stalls while driving
If your vehicle overheats
If you have a flat tire
If your vehicle needs to be towed

If you cannot shift automatic
transmission selector lever
If you lose your keys
Before making these checks, make sure
you have followed the correct starting pro-
cedure given in How to start the engineº
in Part 3 and that you have sufficient fuel.
If the engine is not turning over or is
turning over too slowlyÐ
1. Check that the battery terminals are tight and clean.
2. If the battery terminals are O.K., switch on the interior light.
3. If the light is out, dim or goes out when the starter is cranked, the battery is
discharged. You may try jump starting.
See (c) Jump startingº for further in- structions.
If the light is O.K., but the engine still will
not start, it needs adjustment or repair.
Call a Toyota dealer or qualified repair shop.
NOTICE
Do not pull- or push-start the vehicle. It may damage the vehicle
or cause a collision when the enginestarts. Also the three-way catalytic converter may overheat and be-come a fire hazard.
If the engine turns over at its normal
speed but will not startÐ
1. Check that all the push-on connectors are tight. (For example, connections at the spark plugs, ignition coil and/or dis-
tributor)
2. If the connectors are O.K., the engine may be flooded because of repeated
cranking. See (b) Starting a flooded
engineº for further instructions.

162If the engine will not start, your engine
may be flooded because of repeated cranking.
If this happens, turn the key to STARTº 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 sec-
onds of cranking, release the key, wait a few 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 you eyes, remove
any contaminated clothing and
flush the affected area with water
immediately. Then get immediate
medical attention. If possible, con-
tinue to apply water with a sponge
or cloth while en route to the medi- cal 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.)
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.
4. Make the cable connection in the ordera, b, c, d.
a. Connect the clamp of the positive (red) jumper cable to the positive (+)
terminal on the discharged battery.
b. Connect the clamp at the other
end of the positive (red) jumper cable
to the positive (+) terminal on the
booster battery.c. Connect the clamp of the negative
(black) cable to the negative (-) termi-
nal on the booster battery.
d. Connect the clamp at the other
end of the negative (black) jumper
cable to a solid, stationary,
un-painted, metallic point of the ve-
hicle with the discharged battery.
The recommended connecting points are
shown in the following illustration:

164
Connecting point for 5VZ-FE engine
Connecting point for 3RZ-FE engineDo not connect the cable to or near any
part that moves when the engine is cranked.
NOTICE
When making the connections, do not lean over the battery or
accidentally let the jumper cables or
clamps touch anything except the correct battery terminals or the ground.
5. Start your engine in the normal way. After starting, run it at about 2000 rpm
for several minutes with the accelera- tor pedal lightly depressed.
6. Carefully disconnect the cables in the exact reverse order: the negative
cable and then the positive cable.
7. Carefully dispose of the battery cover clothsÐthey may now contain sulfuricacid.
8. If removed, replace all the battery vent plugs.
If the cause of your battery discharging is
not apparent (for example, lights left on), you should have it checked. If your engine stalls while driving
0
1. Reduce your speed gradually, keeping
a straight line. Move cautiously off the
road to a safe place.
2. Turn on your emergency flashers.
3. Try starting the engine again.
If the engine will not start, see If your ve-
hicle will not startº.If the engine is not running, the
power assist for the brakes and
steering will not work so steering
and braking will be much harder
than usual. CAUTION
