press the Hº button. To reset the min-
utes, depress the Mº button. To ad-
just the time to full hour, depress the
:00º button.
For example, if the :00º button is de-
pressed when the time is between
1:01Ð1:29, the time will change to 1:00.
If the time is between 1:30Ð1:59, the time
will change to 2:00.
When the instrument panel lights are
turned on, the brightness of the time indi-
cation will be reduced.
Once the electrical power source has
been disconnected from the clock, the
time is automatically set to 1:00 (one
o'clock).To operate the cigarette lighter, press
it in. When it becomes heated, it auto-
matically pops out ready for use.
If the engine is not running, the key must
be in the ºACCº position.
Do not hold the cigarette lighter pressed
in.
When finished with your cigarette, thor-
oughly extinguish it in the ashtray to pre-
vent other cigarette butts from catching
fire. After using the ashtray, press it back
in completely.
To remove the ashtray, press down on the
lock spring plate and pull it out.
Use a Toyota genuine cigarette lighter or
equivalent for replacement.

The three-way catalytic converter is
an emission control device installed in
the exhaust system.
The purpose is to reduce pollutants in the
exhaust gas.
CAUTION!

Keep people and combustible ma-
terials away from the exhaust pipe
while the engine is running. The
exhaust gas is very hot.

Do not drive, idle or park your ve-
hicle over anything that might burn
easily such as grass, leaves, paper
or rags.
A large amount of unburned gases
flowing into the three-way catalytic
converter may cause it to overheat
and create a fire hazard. To prevent
this and other damage, observe the
following precautions:
Use only unleaded gasoline.
Do not drive with an extremely low
fuel level; running out of fuel
could cause the engine to misfire,
creating an excessive load on the
three-way catalytic converter.
Do not allow the engine to run at
idle speed for more than 20 min-
utes.
Avoid racing the engine.
Do not push-start or pull-start
your vehicle.
Do not turn off the ignition while
the vehicle is moving.
Keep your engine in good running
order. Malfunctions in the engine
electrical system, electronic igni-
tion system/distributor ignition
system or fuel system could cause
an extremely high three-way cata-
lytic converter temperature.
NOTICEIf the engine becomes difficult to
start or stalls frequently, take your
vehicle in for a check-up as soon
as possible. Remember, your Toyo-
ta dealer knows your vehicle and its
three-way catalytic converter sys-
tem best.
To ensure that the three-way cata-
lytic converter and the engine
emission control system operate
properly, your vehicle must re-
ceive the periodic inspections re-
quired by the Toyota Maintenance
Schedule. For scheduled mainte-
nance information, refer to the
separate Owner's Manual Sup-
plement/Maintenance Scheduleº.

CAUTION!

Avoid inhaling the engine exhaust.
It contains carbon monoxide,
which is a colorless and odorless
gas. It can cause unconsciousness
or even death.

Make sure the exhaust system has
no holes or loose connections.
The system should be checked
from time to time. If you hit some-
thing, or notice a change in the
sound of the exhaust, have the sys-
tem checked immediately.

Do not run the engine in a garage
or enclosed area except for the
time needed to drive the vehicle in
or out. The exhaust gases cannot
escape, making this a particularly
dangerous situation.

Do not remain for a long time in a
parked vehicle with the engine run-
ning. If it is unavoidable, however,
do so only in an unconfined area
and adjust the heating or cooling
system to force outside air into the
vehicle.

Keep the trunk lid or back door
closed while driving. An open or
unsealed trunk lid or back door
may cause exhaust gases to be
drawn into the vehicle. If you must
drive with the trunk lid or back door
open to accommodate a large ob-
ject, close the windows, open all
the instrument panel vents and
have the heating or cooling system
deliver fresh air into the vehicle by
turning the fan to high speed with
the air intake control lever set at the
OUTSIDE AIR position.

To allow proper operation of your
vehicle's ventilation system, keep
the inlet grilles in front of the wind-
shield clear of snow, leaves, or oth-
er obstructions.

If you smell exhaust fumes in the ve-
hicle, drive with the windows open
and the trunk lid or back door
closed. Have the cause immediately
located and corrected.FUNCTIONS OF ENGINE OIL
Engine oil has the primary functions of lu-
bricating and cooling the inside of the en-
gine, and plays a major role in maintaining
the engine in proper working order.
ENGINE OIL CONSUMPTION
It is normal that an engine should con-
sume some engine oil during normal
engine operation. The causes of oil
consumption in a normal engine are
as follows.

Oil is used to lubricate pistons, piston
rings and cylinders. A thin film of oil is
left on the cylinder wall when a piston
moves downwards in the cylinder.
High negative pressure generated
when the vehicle is decelerating sucks
some of this oil into the combustion
chamber. This oil as well as some part
of the oil film left on the cylinder wall is
burned by the high temperature com-
bustion gases during the combustion
process.

Oil is also used to lubricate the stems
of the intake valves. Some of this oil is
sucked into the combustion chamber
together with the intake air and is
burned along with the fuel. High tem-
perature exhaust gases also burn the
oil used to lubricate the exhaust valve
stems.

Even if the power assist is com-
pletely lost, the brakes will still
work. But you will have to push the
pedal hardÐmuch harder than nor-
mal. And your braking distance will
be longer.
ANTI-LOCK BRAKE SYSTEM (vehicles
with ABSº warning light)
The anti-lock brake system is designed to
prevent lock-up of the wheels during sud-
den braking or braking on slippery road
surfaces. This assists the driver in con-
trolling the vehicle under these circum-
stances.
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).
You may hear a 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 malfunction.When the anti-lock brake system function
is in action, you may feel the brake pedal
pulsating and hear a noise. In this situa-
tion, to let the anti-lock brake system
work for you, just hold the brake pedal
down more firmly. Do not pump the brake.
The brake pedal pulsation caused by the
anti-lock brake system may indicate haz-
ardous road surface conditions. Although
the anti-lock brake system assists in pro-
viding vehicle control, it is still important to
drive with all due care, because the anti-
lock brake system cannot overcome the
laws of physics that act on your vehicle:

Braking capability is dependent on tire
friction with the road surface.

Even though the anti-lock brake sys-
tem is operating, a driver cannot main-
tain full control on certain slippery road
surfaces, when cornering at high
speeds, or in violent maneuvers.

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 ve-
hicles not fitted with an anti-lock brake
system, your vehicle may require 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.

11 6 Before starting the engine, be sure to fol-
low the instructions in (a) Before crank-
ingº.
Normal starting procedure
The multiport fuel injection system/se-
quential 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
STARTº. Release it when the engine
starts.
2. After the engine runs for about 10 sec-
onds, you are ready to drive.
If the weather is below freezing, let the en-
gine 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 startÐ
See If your vehicle will not startº in Part 4.

Do not crank for more than 15 sec-
onds at a time. This may overheat
the starter and wiring systems.
Do not race a cold engine.
If the engine becomes difficult to
start or stalls frequently, have the
engine checked immediately.
NOTICE

Always slow down in gusty cross-
winds. 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 park-
ing brake, and place the transmission
in Pº (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 parking brake pulled. If they
still do not work safely, pull to the side
of the road and call a Toyota dealer for
assistance.
CAUTION!

Before driving off, make sure 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 run-
ning.

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 ac-
celeration 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 consult a tire dealer to de-
termine 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.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 to
check 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 deal-
erÐhe 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 as washer fluid be-
cause 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 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.

Because stopping distance may be in-
creased, vehicle-to-vehicle distance
should be increased when towing a
trailer. For each 16 km/h (10 mph) of
speed, allow at least one vehicle and
trailer length between you and the ve-
hicle ahead. Avoid sudden braking as
you may skid, resulting in jackknifing
and loss of control. This is especially
true on wet or slippery surfaces.

Avoid jerky starts or sudden accelera-
tion. If your vehicle has manual trans-
mission, prevent excessive clutch slip-
page by keeping engine rpm low and
not racing the engine. Always start out
in first gear.

Avoid jerky steering and sharp turns.
The trailer could hit your vehicle in a
tight turn. Slow down before making a
turn to avoid the necessity of sudden
braking.

Remember that when making a turn,
the trailer wheels will be closer than
the vehicle wheels to the inside of the
turn. Therefore, compensate for this
by making a larger than normal turning
radius with your vehicle.
Crosswinds and rough roads will ad-
versely affect handling of your vehicle
and trailer, causing sway. Pay atten-
tion to the rear from time to time to pre-
pare yourself for being passed by large
trucks or buses, which may cause your
vehicle and trailer to sway. If swaying
happens, firmly grip the steering wheel
and reduce speed immediately but
gradually. Never increase speed.
Steer straight ahead. If you make no
extreme correction with the steering or
brakes, the vehicle and trailer will sta-
bilize.

Be careful when passing other ve-
hicles. Passing requires considerable
distance. After passing a vehicle, do
not forget the length of your trailer and
be sure you have plenty of room be-
fore changing lanes.

In order to maintain engine braking effi-
ciency, do not use fifth gear (manual
transmission or overdrive (automatic
transmission).
Because of the added load of the trail-
er, your vehicle's engine may overheat
on hot days (at temperatures over
305C [855F]) when going up a long or
steep grade with a trailer. If the engine
coolant temperatue gauge indicates
overheating, immediately turn off the
air conditioning (if in use), pull off the
road and stop in a safe spot. Refer to
If your vehicle overheatsº in Part 4 of
this manual.

Always place wheel blocks under both
the vehicle and trailer wheels when
parking. Apply the parking brake firm-
ly. Put the transmission in Pº (auto-
matic) or in first or reverse (manual).
Avoid parking on a slope with a trailer,
but if it cannot be avoided, do so only
after performing the following:
1. Apply the brakes and hold.
2. Have someone place wheel blocks un-
der both the vehicle and trailer wheels.
3. When the wheel blocks are in place,
release your brakes slowly until the blocks
absorb the load.
4. Apply the parking brake firmly.
5. Shift into first or reverse (manual) or
Pº (automatic) and turn off the engine.ProCarManuals.com

122 When restarting out after parking on a
slope:
1. With the transmission in Pº position
(automatic) or the clutch pedal depressed
(manual), start the engine. (With an auto-
matic transmission, be sure to keep the
brake pedal depressed.)
2. Shift into gear.
3. Release the parking brake (also foot
brake on automatic transmission ve-
hicles) and slowly pull or back away from
the wheels blocks. Stop and apply your
brakes.
4. Have someone retrieve the blocks.
CAUTION!

Do not exceed 72 km/h (45 mph) or
the posted towing speed limit,
whichever is lower. Because insta-
bility (swaying) of a towing vehicle-
trailer combination usually in-
creases as the speed increases, ex-
ceeding 72 km/h (45 mph) may
cause loss of control.

Slow down and downshift before
descending steep or long downhill
grades. Do not make sudden down-
shifts.

Avoid holding the brake pedal
down too long or too frequently.
This could cause the brakes to
overheat and result in reduced
braking efficiency.Getting more kilometers/mileage from a li-
ter/gallon of fuel is easyÐjust take it easy.
It will help make your vehicle last longer,
too. Here are some specific tips on how to
save money on both fuel and repairs:

Keep your tires inflated at the cor-
rect pressure. Underinflation causes
tire wear and wastes fuel. See Chapter
7-2 for instructions.

Do not carry unneeded weight in
your vehicle. Excess weight puts a
heavier load on the engine, causing
greater fuel consumption.

Avoid lengthy warm-up idling.
Once the engine is running smoothly,
begin drivingÐbut gently. Remember,
however, that on cold winter days this
may take a little longer.

Accelerate slowly and smoothly.
Avoid jackrabbit starts. Get into high
gear as quickly as possible.

Avoid long engine idling. If you have
a long wait and you are not in traffic, it
is better to turn off the engine and start
again later.

Avoid engine lug or overrevving.
Use a gear position suitable for the
road on which you are travelling.
Avoid continuous speeding up and
slowing down. Stop-and-go driving
wastes fuel.

Avoid unnecessary stopping and
braking. Maintain a steady pace. Try
to time the traffic signals so you only
need to stop as little as possible or take
advantage of through streets to avoid
traffic lights. Keep a proper distance
from other vehicles to avoid sudden
braking. This will also reduce wear on
your brakes.

Avoid heavy traffic or traffic jams
whenever possible.

Do not rest your foot on the clutch
or brake pedal. This causes needless
wear, overheating and poor fuel econ-
omy.

Maintain a moderate speed on
highways. The faster you drive, the
greater the fuel consumption. By re-
ducing your speed, you will cut down
on fuel consumption.

Keep the front wheels in proper
alignment. Avoid hitting the curb and
slow down on rough roads. Improper
alignment not only causes faster tire
wear but also puts an extra load on the
engine, which, in turn, wastes fuel.

Keep the bottom of your vehicle
free from mud, etc. This not only
lessens weight but also helps prevent
corrosion.

Keep your vehicle tuned-up and in
top shape. A dirty air cleaner, carbu-
retor out of adjustment, improper valve
clearance, dirty plugs, dirty oil and
grease, brakes not adjusted, etc. all
lower engine performance and con-
tribute to poor fuel economy. For lon-
ger life of all parts and lower operating
costs, keep all maintenance work on
schedule, and if you often drive under
severe conditions, see that your ve-
hicle receives more frequent mainte-
nance. (For scheduled maintenance
information, please refer to the sepa-
rate Owner's Manual Supplement/
Maintenance Scheduleº).
CAUTION!
Never turn off the engine to coast
down hills. Your power steering and
brake booster will not function with-
out the engine running. Also, the
emission control system operates
properly only when the engine is
running.
