When driving offroad or in rugged
terrain, do not drive at excessive
speeds, jump, make sharp turns,
strike objects, etc. This may cause
loss of control or vehicle rollover
causing death or serious injury. You
are also risking expensive damage
to your vehicle’s suspension and
chassis.
Do not drive horizontally across
steep slopes. Driving straight up or
straight down is preferred. Your ve-
hicle (or any similar offroad ve-
hicle) can tip over sideways much
more easily than forward or back-
ward.
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:
Avoid full throttle acceleration when
starting and driving.
Avoid racing the engine.
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 mix
−ups, your
Toyota has a smaller fuel tank opening.
The special nozzle on pumps with un-
leaded fuel will fit it, but the larger stan-
dard nozzle on pumps with leaded gas will
not.
At a minimum, the gasoline you use
should meet specifications of ASTM
D4814 in the U.S.A. and CGSB 3.5 −M93
in Canada.
NOTICE
Do not use leaded gasoline. Use of
leaded gasoline will cause the three
way catalytic converter to lose its ef-
fectiveness and the emission control
system to function improperly. Also,
this can increase maintenance costs.

Make sure the engine oil viscosity is
suitable for the cold weather.
See Section 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 deal-
er—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
inserting 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.
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” (automatic) or into first or reverse
(manual) 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.
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
vehicle are tire chains, window scraper,
bag of sand or salt, flares, small shovel,
jumper cables, etc.
Your vehicle is not designed to be
dinghy towed (with four wheels on the
ground) behind a motorhome.
NOTICE
Do not tow your vehicle with four
wheels on the ground. This may
cause serious damage to your vehicle.

Before making these checks, make sure
you have followed the correct starting pro-
cedure given in “How to start the engine”
in Section 3 and that you have sufficient
fuel.
If the engine is not turning over or is
turning over too slowly—
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 start-
ing. See “(c) Jump starting” for further
instructions.
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 pushstart the ve-
hicle. Your vehicle may suddenly
move when the engine starts, and
may damage itself or cause a colli-
sion. Also the threeway catalytic
converter may overheat and become a
fire hazard.
If the engine turns over at its normal
speed but will not start— 1. Turn the ignition key to “ACC” or “LOCK” and try starting the engine
again.
2. If the engine will not start, the engine may be flooded because of repeated
cranking. See “(b) Starting a flooded
engine” for further instructions.
3. If the engine still will not start, it needs adjustment or repair. Call a Toyota
dealer or qualified repair shop. If the engine will not start, your engine
may be flooded because of repeated
cranking.
If this happens, turn the key to “START”
with the accelerator pedal fully depressed.
Keep the key and accelerator pedal in
these positions for 15 seconds and re-
lease 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 overheat
the starter and wiring systems.

If the engine will not start, your engine
may be flooded because of repeated
cranking.
If this happens, turn the ignition key to
“START” with the accelerator pedal held
down, and hold the key at this position for
about 30 seconds. Then the cranking hold
function stops cranking automatically, and
you can try starting the engine with your
foot off the accelerator pedal.
If the engine does not start, 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. 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.
Warning: Battery posts, terminals
and related accessories contain lead
and lead compounds, chemicals
known to the State of California to
cause cancer and reproductive
harm. Wash hands after handling.
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 PROCEDURE
1. If the booster battery is installed in another vehicle, make sure the vehicles
are not touching. Turn off all unneces-
sary lights and accessories.
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.

terminal on the booster battery.
d. Connect the clamp at the other end
of the negative (black) jumper cable to
a solid, stationary, unpainted, metallic
point of the vehicle with the discharged
battery.
The recommended connecting points
are shown in the following illustrations:

Connecting point for 2UZFE engine
Do not connect the cable to or near
any part that moves when the engine
is cranked.
CAUTION
When making the connections, to
avoid serious injury, do not lean over
the battery or accidentally let the
jumper cables or clamps touch any-
thing except the correct battery termi-
nals or the ground.
5. Start your engine in the normal way.
After starting, run it at about 2000 rpm
for several minutes with the accelerator
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 cloths—they may now contain sulfuric
acid.
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 at your Toyota
dealer. If your engine stalls while driving...
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. Turn the ignition key to “ACC” or “LOCK”, and try starting the engine
again.
If the engine will not start, see “If your
vehicle will not start”.
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.
