106If your engine knocks...
If you detect heavy knocking even when
using the recommended fuel, or if you
hear steady knocking while holding a
steady speed on level roads, consult your
Toyota dealer.
However, now and then, you may notice
light knocking for a short time while accel-
erating or driving up hills. This is no cause
for concern.
GASOLINES CONTAINING DETER-
GENT ADDITIVES
Toyota recommends use of gasolines
that contain detergent additives to
avoid build-up of engine deposits.
For further details, ask your Toyota dealer
or a local gasoline retailer.
GASOLINES CONTAINING MTBE
Gasolines that contain MTBE (Methyl
Tertiary-Butyl Ether) are available in
the market. If you use a gasoline mixed
with MTBE, make certain that it does
not contain more than 15% of MTBE.
If the use of gasolines containing MTBE
causes poor driveability and/or poor fuel
economy, you should discontinue the use
of fuels containing MTBE.GASOLINES CONTAINING ALCOHOL
If you use gasohol in your Toyota, be
sure that it is unleaded, has an octane
rating no lower than 87 and does not
contain more than 10% ethanol.
Gasohol is a mixture of gasoline and etha-
nol.
Toyota does not recommend the use of
gasolines containing methanol. If you use
gasoline containing methanol, use only
gasoline meeting the requirements above
and also containing less than 5% metha-
nol with cosolvents and corrosion inhibi-
tors for methanol.

Do not use gasohol other than
stated above. It will cause fuel
system damage or vehicle perfor-
mance problems.
If driveability problems are en-
countered (poor hot starting, va-
porizing, engine knock, etc), dis-
continue the use.
Take care not to spill gasohol dur-
ing refueling. Gasohol may cause
paint damage.

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.
Facts about engine oil
consumption Engine exhaust cautions
ProCarManuals.com

109 The amount of engine oil consumed
depends 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 be-
come 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 fuel or moisture, making it ap-
pear that the oil level has not changed.
The 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 at 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.
NOTICE
Failure to check the oil level
regularly could lead to serious
engine trouble due to insufficient
oil.
For detailed information on oil level check,
see Checking the engine oil levelº in
Chapter 7-2.TANDEM MASTER CYLINDER BRAKE
SYSTEM
The tandem master cylinder brake system
is a hydraulic system with two separate
sub-systems. If either sub-system should
fail, the other will still work. However, the
pedal will be harder to press, and your stop-
ping 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!
CAUTION!

Do not pump the brake pedal if the
engine stalls. Each push on the
pedal uses up your vacuum re-
serve.

11 2When stowing luggage or cargo in the ve-
hicle, observe the following:

Put luggage or cargo in the trunk or
luggage compartment when at all pos-
sible. Be sure all items are secured in
place.

Be careful to keep the vehicle bal-
anced. Locating the weight as far for-
ward as possible helps maintain bal-
ance.

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

To prevent luggage or packages
from sliding forward during brak-
ing, do not stack anything in the
enlarged trunk room or the lug-
gage compartment higher than the
seatbacks. Keep luggage or pack-
ages low, as close to the floor as
possible.

Never allow anyone to ride in the
enlarged trunk room or the luggage
compartment. It is not designed for
passengers. They should ride in
their seats with their seat belts
properly fastened. Otherwise, they
are much more likely to suffer seri-
ous bodily injury, in the event of
sudden braking or a collision.

Do not place anything on the filler
panel behind the rear seatback or
luggage cover. Such items may be
thrown about and possibly injure
people in the vehicle during sud-
den 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 view. Or they may move during
sharp vehicle acceleration or turn-
ing, and impair the driver's control
of the vehicle. In an accident they
may injure the vehicle occupants.
Do not load the vehicle beyond the
vehicle capacity weight specified in
Part 8.
NOTICE
The vehicle identification number (VIN)
is the legal identifier for your vehicle.
Its location is shown in the illustration.
The vehicle indentification number (VIN)

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.Manual transmission: Press the
clutch pedal to the floor and shift the
transmission into neutral. Hold the clutch
pedal to the floor until the engine is
started. A starter safety device will pre-
vent the starter from operating if the
clutch pedal is not fully depressed.
Automatic transmission: Put the selec-
tor lever in Pº. If you need to restart the
engine while the vehicle is moving, put the
selector lever in Nº. A starter safety de-
vice will prevent the starter from operating
if the selector lever is in any drive position.
4.Automatic transmission only: De-
press the brake pedal and hold it to the
floor until driving off.

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.

11 8 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 pas-
senger-carrying vehicle. Towing a trailer
will have an adverse effect on handling,
performance, braking, durability and driv-
ing economy (fuel consumption, etc.). Your
safety and satisfaction depend on the
proper use of correct equipment and cau-
tious driving habits. For your safety and the
safety of others, you must not overload
your vehicle or trailer. Toyota warranties do
not apply to damage or malfunction caused
by towing a trailer for commercial pur-
poses. Ask your local Toyota dealer for fur-
ther 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.
CAUTION!

The total trailer weight (trailer
weight plus its cargo load) must
not exceed 680 kg (1500 lb.). Ex-
ceeding this weight is dangerous.
CAUTION!

The gross vehicle weight must not
exceed the Gross Vehicle Weight
Rating (GVWR) indicated on the
Certification Label. The gross ve-
hicle weight is the sum of weights
of the unloaded vehicle, driver,
passengers, luggage, hitch and
trailer tongue load. It also includes
the weight of any special equip-
ment installed on your vehicle.

The load on either the front or rear
axle resulting from distribution of
the gross vehicle weight on both
axles must not exceed the Gross
Axle Weight Rating (GAWR) listed
on the Certification Label.
Trailer towing
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.

123
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.
