Do not allow the engine to run atidle speed for more than 20 min-
utes.
Avoid racing the engine.
Do not push-start or pull-startyour vehicle.
Do not turn off the ignition whilethe vehicle is moving.
Keep your engine in good running
order. Malfunctions in the engine electrical system, electronic igni-
tion system/distributor ignitionsystem or fuel system engine ex-haust cautions could cause an ex-
tremely high three-way catalytic converter temperature.
If the engine becomes difficult tostart or stalls frequently, take your
vehicle in for a check-up as soon as possible. Remember, your To-
yota dealer knows your vehicleand its three-way catalytic con-verter system best.
To ensure that the three-way cata-lytic converter and the engine
emission control system operateproperly, your vehicle must re-ceive the periodic inspections re-
quired by the T oyota Maintenance
Schedule. For scheduled mainte- nance information, refer to the
separate Owner's Manual Sup-plement/Maintenance Scheduleº.CAUTION!

Avoid inhaling the engine ex-
haust. It contains carbon monox-
ide, which is a colorless and odor-
less gas. It can cause uncon-
sciousness or even death.

Make sure the exhaust system
has no holes or loose connec-
tions. The system should be
checked from time to time. If you
hit something, or notice a change
in the sound of the exhaust, have
the system 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 paticularly
dangerous situation.

Do not remain for a long time in a
parked vehicle with the engine
running. If it is unavoidable, how-
ever, 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 closed while
driving. An open or unsealed
trunk lid may cause exhaust
gases to be drawn into the ve-
hicle. If you must drive with the
trunk lid open to accommodate a
large object, 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 button set at the outside
air mode.

To allow proper operation of your
vehicle's ventilation system, keep
the inlet grilles in front of the
windshield clear of snow, leaves,
or other obstructions.

If you smell exhaust fumes in the
vehicle, drive with the windows
open and the trunk lid closed.
Have the cause immediately lo-
cated 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 cham-
ber 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.
The amount of engine oil consumed de-
pends on the viscosity of the oil, the
quality of the oil and the conditions the
vehicle is driven under.
More oil is consumed by high-speed driv-
ing and frequent acceleration and decel-
eration.
A new engine consumes more oil, since
its pistons, piston rings and cylinder walls
have not become conditioned.
When judging the amount of oil con-
sumption, note that the oil may become
diluted and make it difficult to judge the
true level accurately.
As an example, if a vehicle is used for re-
peated short trips, and consumes a nor-
mal amount of oil, the dipstick may not
show any drop in the oil level at all, even
after 1000 km (600 miles) or more. This
is because the oil is gradually becoming
diluted with the fuel or moisture, making it
appear that the oil level has not changed.
Facts about engine oil
consumption
ProCarManuals.com

134The diluting ingredients evaporate out
when the vehicle is then driven at high
speeds, as on an expressway, making it
appear that oil is excessively consumed
after driving as high speeds.
IMPORTANCE OF ENGINE OIL LEVEL
CHECK
One of the most important points in proper
vehicle maintenance is to keep the engine
oil at the optimum level so that oil function
will
not be impaired. Therefore, it is essen-
tial that the oil level be checked regularly.
Toyota recommends that the oil level be
checked every time you refuel the vehicle.
Failure to check the oil level
regularly could lead to serious
engine trouble due to insufficientoil.
NOTICE
For detailed information on the oil level
check, see Checking the engine oil levelº
in Chapter 7-2.
Your engine is fitted with twin ground elec-
trode spark plugs.
Use only twin ground electrode
spark plugs for your engine
performance.
NOTICE
TANDEM MASTER CYLINDER BRAKE
SYSTEM
The tandem master cylinder brake sys-
tem is a hydraulic system with two sepa-
rate sub-systems. If either sub-system
should fail, the other w ill still work. Howev-
er, 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 reserve
vacuum for one or two stopsÐbut no
more!

The brake pad wear limit indicators on
your disc brakes give a warning noise
when the brake pads are worn to
where replacement is required.
If you hear a squealing or scraping noise
while driving, have the brake pads
checked and replaced by your Toyota
dealer as soon as possible. Expensive ro-
tor damage can result if the pads are not
replaced when necessary.When stowing luggage or cargo in the ve-
hicle, observe the following:


Put luggage or cargo in the trunk when
at all possible. Be sure all items are se-
cured in place.

Be careful to keep the vehicle
balanced. Locating the weight as far
forward as possible helps maintain
balance.

For better fuel economy, do not carry
unneeded weight.
CAUTION!

Do not place anything on the filler
panel behind the rear seatback.
Such items may be thrown about
and possibly injure people in the
vehicle during sudden braking or
an accident.

Do not drive with objects left on
top of the instrument panel. They
may interfere with the driver's
field of veiw. Or they may move
during sharp vehicle acceleration
or turning, and impair the driver's
control of the vehicle. In an acci-
dent they may injure the vehicle
occupants.
Do not load the vehicle beyond the
vehicle capacity weight specified in
Part 8.

How to save fuel and make your
vehicle last longer, too
1. Check the area around the vehicle be-
fore entering it.
2. Adjust seat position, seatback angle, head restraint height and steering
wheel angle.
3. Adjust inside and outside rear view mirrors.
4. Lock all doors.
5. Fasten seat belts. 1. Apply the parking brake firmly.
2. Turn off unnecessary lights and acces-
sories.
3. Put the selector lever in Pº. If you need to restart the engine while the ve-
hicle is moving, put the selector lever
in Nº. A starter safety device will pre-
vent the starter from operating if the
selector lever is in any drive position.
4. Depress the brake pedal and hold it to the floor until driving off.

142Before 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 en-
gine 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 30 sec-
onds at a time. This may overheat
the starter and wiring systems.
Do not race a cold engine.
If the engine becomes difficult tostart or stalls frequently, have theengine 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. 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 depressed. If
they still do not work safely, pull to the
side of the road and call a T oyota deal-
er for assistance.

CAUTION

Before driving off, make sure that
the parking brake if 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 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 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 lon-
ger stopping distance, and it may
pull to one side when the brakes are
applied. Also, the parking 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 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
ProCarManuals.com

144Use 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 and block the rear wheels. Do not use
the parking brake, or snow or water accu-
mulated 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 ve-
hicle are tire chains, window scraper, bag
of sand or salt, flares, small shovel, jump-
er cables, etc.
Your vehicle is designed primarily as a
passenger-carrying vehicle. Towing a
trailer will have an adverse effect on han-
dling, performance, braking, durability
and driving economy (fuel consumption,
etc.). Your safety and satisfaction
depend
on the proper use of correct equipment
and cautious driving habits. For your safe-
ty and the safety of others, you must not
overload your vehicle or trailer. Toyota
warranties do not apply to damage or mal-
function caused by towing a tailer for com-
merical purposes. Ask your local Toyota
dealer for further details before towing.
WEIGHT LIMITS
Before towing, make sure the total trailer
weight, gross vehicle weight, gross axle
weight and trailer tongue load are all with-
in the limits.
The total trailer weight and tongue load
can be measured with platform scales
found at a highway weighing station,
building supply company, trucking com-
pany, junk yard, etc.
