IMPORTANCE OF ENGINE OIL LEVEL
CHECK
One of the most important points in prop-
er vehicle maintenance is to keep the en-
gine oil at the optimum level so that oil
function will not be impaired. Therefore, it
is essential that the oil level be checked
regularly. Toyota recommends that the oil
level be checked every time you refuel
the vehicle.
NOTICE
Failure to check the oil level regularly
could lead to serious engine troubledue to insufficient oil.
For detailed information on oil level check,
see ªChecking the engine oil levelº in Sec-
tion 7±2.
Your engine is fitted with twin ground
electrode spark plugs.
NOTICE
Use only twin ground electrode spark
plugs for your engine performance.
Brake system
The tandem master cylinder brake system
is a hydraulic system with two separate
sub±systems. If either s ub±system should
fail, the other will still work. However, the
pedal will be harder to press, and your
stopping distance will be longer. Also, the
brake system warning light may come on.
CAUTION
Do not drive your vehicle with only a
single brake system. Have your
brakes fixed immediately.
BRAKE BOOSTER
The brake booster uses engine vacuum to
power±assist the brakes. If the engine
should quit while you are driving, you can
bring the vehicle to a stop with normal
pedal pressure. There is enough reserved
vacuum for one or two stopsÐbut no
more!

CAUTION

Do not pump the brake pedal if the
engine stalls. Each push on the
pedal uses up your reserved vacu-
um.

Even if the power assist is com-
pletely lost, the brakes will still
work. But you will have to push the
pedal hard, much harder than nor-
mal. And your braking distance will
be longer.
ANTI±LOCK BRAKE SYSTEM
(with ªABSº warning light)
The anti±lock brake system is designed
to help prevent lock±up of the wheels
during a sudden braking or braking on
slippery road surfaces. This assists in
providing directional stability and steer-
ing performance of the vehicle under
these circumstances.
Effective way to press the ABS brake
pedal: When the anti±lock brake system
function is in action, you may feel the
brake pedal pulsating and hear a noise.
In this situation, to let the anti±lock
brake system work for you, just hold the
brake pedal down more firmly. Do not
pump the brake in a panic stop. This
will result in reduced braking performan-
ce.
The anti±lock brake system becomes op-
erative after the vehicle has accelerated
to a speed in excess of approximately 10
km/h (6 mph). It stops operating when the
vehicle decelerates to a speed below
approximately 5 km/h (3 mph).
Depressing the brake pedal on slippery
road surfaces such as on the manhole
cover, the steel plate under the construc-
tion, joints in the bridge, etc. on a rainy
day tends to activate the anti±lock brake
system.
You may hear a click or motor sound in
the engine compartment for a few seconds
when the engine is started or just after
the vehicle is started. This means that the
anti±lock brake system is in the self±
check mode, and does not indicate a mal-
function. When the anti±lock brake system is ac-
tivated, the following conditions may
occur. They do not indicate a malfunc-
tion of the system:

You may hear the anti±lock brake sys-
tem operating and feel the brake pedal
pulsating and the vibrations of the ve-
hicle body and steering wheel. You
may also hear the motor sound in the
engine compartment even after the ve-
hicle is stopped.

At the end of the anti±lock brake sys-
tem activation, the brake pedal may
move a little forward.

ÐEngine number
5VZ±FE engine
2UZ±FE engine
The engine number is stamped on the
engine block as shown. Your new vehicle carries theft preven-
tion labels which are approximately 56
mm (2.20 in.) by 16 mm (0.63 in.).
The purpose of these labels is to reduce
the incidence of vehicle thefts by fac
ilitat-
ing the tracing and recovery of parts from
stolen vehicles. The label is designed so
that once it is applied to a surface, any
attempt to remove it will result in destroy-
ing the integrity of the label. Transferring
these labels intact from one part to anoth-
er, will be impossible.
NOTICE
You should not attempt to remove the
theft prevention labels as it may vio-late certain state or federal laws.

De-
press the brake pedal and hold it to
the floor until driving off.
(b) Starting the engine
Before starting the engine, be sure to fol-
low the instructions in ª(a) Before crank-
ingº.
Normal starting procedure
The multiport fuel injection system/sequen-
tial multiport fuel injection system in your
engine automatically controls the proper
air±fuel mixture for starting. You can start
a cold or hot engine as follows:
1. With your foot off the accelerator ped- al, crank the engine by turning the key
to ªSTARTº. Release it when the en-
gine starts.
2. After the engine runs for about 10 se- conds, you are ready to drive.
If the weather is below freezing, let the
engine warm up for a few minutes before
driving.
If the engine stalls...
Simply restart it, using the correct proce-
dure given in normal starting.
If the engine will not start...
See ªIf your vehicle will not startº in Sec-
tion 4.

NOTICE
Do not crank for more than 30 se-
conds at a time. This may overheatthe starter and wiring systems.
Do not race a cold engine.
If the engine becomes difficult tostart or stalls frequently, have the
engine checked immediately.

Always slow down in gusty crosswinds.
This will allow you much better control.

Drive slowly onto curbs and, if pos-
sible, at a right angle. Avoid driving
onto high, sharp±edged objects and
other road hazards. Failure to do so
can lead to severe tire damage result-
ing in tire bursts.

When parking on a hill, turn the front
wheels until they touch the curb so
that the vehicle will not roll. Apply the
parking brake, and place the transmis-
sion in ªPº (automatic) or in first or
reverse (manual). If necessary, block
the wheels.

Washing your vehicle or driving through
deep water may get the brakes wet. To
see whether they are wet, check that
there is no traffic near you, and then
press the pedal lightly. If you do not
feel a normal braking force, the brakes
are probably wet. To dry them, drive
the vehicle cautiously while lightly
pressing the brake pedal with the park-
ing brake applied. If they still do not
work safely, pull to the side of the road
and call a Toyota dealer for assistance.

Four±wheel drive modelsÐToyota rec-
ommends not using four±wheel drive on
dry hard±surfaced roads, because four±
wheel driving will cause unnecessary
noise and wear, and poor fuel econo-
my.

Four±wheel drive modelsÐIn cold tem-
peratures, noise may occur when driv-
ing in two±wheel drive before the trans-
fer is warmed up. Therefore, first drive
in four±wheel drive until the transfer is
warmed up.

CAUTION

Before driving off, make sure that
the parking brake is fully released
and the parking brake reminder
light is off.

Do not leave your vehicle unat-
tended while the engine is running.

Do not rest your foot on the brake
pedal while driving. It can cause
dangerous overheating, needless
wear, and poor fuel economy.

To drive down a long or steep hill,
reduce your speed and downshift.
Remember, if you ride the brakes
excessively, they may overheat and
not work properly.

Be careful when accelerating, up-
shifting, downshifting or braking on
a slippery surface. Sudden accelera-
tion or engine braking could cause
the vehicle to spin or skid.

Do not drive in excess of the speed
limit. Even if the legal speed limit
permits it, do not drive over 140
km/h (85 mph) unless your vehicle
has high±speed capability tires.
Driving over 140 km/h (85 mph) may
result in tire failure, loss of control
and possible injury. Be sure to con-
sult a tire dealer to determine
whether the tires on your vehicle
are high±speed capability tires or
not before driving at such speeds.

Do not continue normal driving
when the brakes are wet. If they are
wet, your vehicle will require a
longer stopping distance, and it
may pull to one side when the
brakes are applied. Also, the park-
ing brake will not hold the vehicle
securely.
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 trav-
el.
b. Respect private property. Get owner 's permission before entering private prop-
erty.
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 pre-
vent 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.

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.

In a rollover crash, an unbelted per-
son is significantly more likely to
die than a person wearing a seat
belt. Therefore, the driver and all
passengers should fasten their seat
belts whenever the vehicle is mov-
ing.

When driving off±road 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.
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, transmissionand transfer case, reducing the gear
oil's lubricating qualities.
Sand and mud that has accumulatedin brake drums and around brake
discs may affect braking efficiencyand may damage brake system com-ponents.
