FUNCTIONS OF ENGINE OIL
Engine oil has the primary functions of
lubricating and cooling the inside of the
engine, and plays a major role in main-
taining 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 pis-
ton 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 combustion
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.
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
repeated 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
appear 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 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 trouble
due to insufficient oil.
For detailed information on oil level check,
see ªChecking the engine oil levelº on
page 220 in Section 7±2.

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 mo-
ving.

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 water
and the bottom of the river bed for
firmness. Drive slowly and avoid
deep water.
Take all necessary safety measures
to ensure that water damage to the
engine or other components does
not occur.
Water entering the engine air intake
will cause severe engine damage.
Water can wash the grease from
wheel bearings, causing rusting and
premature failure, and may also en-
ter the differentials, transmission
and transfer case, reducing the gear
oil's lubricating qualities.
Sand and mud that has accumulated
in brake drums and around brake
discs may affect braking efficiency
and may damage brake system com-
ponents.
Always perform a maintenance in-
spection after each day of off±road
driving that has taken you through
rough terrain, sand, mud, or water.
For scheduled maintenance informa-
tion, refer to the ªScheduled Main-
tenance Guideº or ªOwner's Manual
Supplementº.
Winter driving tips
Make sure you have a proper freeze
protection of engine coolant.
Your coolant must contain ethylene±glycol
type coolant for a proper corrosion
protection of aluminum components. Use
ªTOYOTA Long Life Coolantº or equivalent.
See page 221 in Section 7±2 for details
about coolant type selection.
NOTICE
Do not use alcohol type antifreeze or
plain water alone.
When it is extremely cold, we recommend
to use 60% solution for your Toyota, to
provide protection down to about ±50C
(±58F). Do not use more than 70% solu-
tion for better coolant performance.
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 start-
ing. Section 7±3 tells you how to visually
inspect the battery. Your Toyota dealer
and most service stations will be pleased
to check the level of charge.

Crosswinds and rough roads will ad-
versely affect handling of your vehicle
and trailer, causing sway. Pay attention
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 stabilize.

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
30C [85F]) when going up a long or
steep grade with a trailer. If the engine
coolant temperature gauge indicates
overheating, immediately turn off the air
conditioning (if in use), pull off the road
and stop in a safe spot. Refer to ªIf
your vehicle overheatsº on page 186 in
Section 4.

Always place wheel blocks under both
the vehicle and trailer wheels when
parking. Apply the parking brake firmly.
Put the transmission in ªPº (automatic)
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
ªPº (automatic) and turn off the engine.When restarting out after parking on a
slope:
1. With the transmission in ªPº position
(automatic) or the clutch pedal de-
pressed (manual), start the engine.
(With an automatic transmission, be
sure to keep the brake pedal de-
pressed.)
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 wheel 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.

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 corro-
sion.

Keep your vehicle tuned±up and in
top shape. A dirty air cleaner, improp-
er valve clearance, dirty plugs, dirty oil
and grease,brakes not adjusted, etc. all
lower engine performance and contrib-
ute to poor fuel economy. For longer
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 vehicle
receives more frequent maintenance.
(For scheduled maintenance informa-
tion, please refer to the ªScheduled
Maintenance Guideº or ªOwner 's Manu-
al Supplementº).
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 run-
ning.

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 ªACCº or
ªLOCKº, and try starting the engine
again.
If the engine will not start, see ªIf your
vehicle will not startº on page 182.
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.
If your vehicle overheats
If your engine coolant temperature
gauge indicates overheating, if you ex-
perience a loss of power, or if you hear
a loud knocking or pinging noise, the
engine has probably overheated. You
should follow this procedure...
1. Pull safely off the road, stop the ve-
hicle and turn on your emergency
flashers. Put the transmission in ªPº
(automatic) or neutral (manual) and ap-
ply the parking brake. Turn off the air
conditioning if it is being used.
2. If coolant or steam is boiling out of the
radiator or reservoir, stop the engine.
Wait until the steam subsides before
opening the hood. If there is no coolant
boiling over or steam, leave the engine
running and make sure the electric
cooling fan is operating. If it is not,
turn the ignition off.
CAUTION
To help avoid personal injury, keep
the hood closed until there is no
steam. Escaping steam or coolant is
a sign of very high pressure.
3. Look for obvious coolant leaks from the
radiator, hoses, and under the vehicle.
However, note that water draining from
the air conditioning is normal if it has
been used.
CAUTION
When the engine is running, keep
hands and clothing away from the
moving fan and engine drive belts.
4. If the coolant is leaking, stop the en-
gine immediately. Call a Toyota dealer
for assistance.
5. If there are no obvious leaks, check
the coolant reservoir. If it is dry, add
coolant to the reservoir while the en-
gine is running. Fill it about half full.
CAUTION
Do not attempt to remove the radiator
cap when the engine and radiator are
hot. Serious injury could result from
scalding hot fluid and steam blown
out under pressure.

Toyota, through its diligent research, de-
sign and use of the most advanced
technology available, has done its part to
help prevent corrosion and has provided
you with the finest quality vehicle
construction. Now, it is up to you. Proper
care of your Toyota can help ensure long±
term corrosion prevention.
The most common causes of corrosion
to your vehicle are:

The accumulation of road salt, dirt and
moisture in hard±to±reach areas under
the vehicle.

Chipping of paint, or undercoating
caused by minor accidents or by
stones and gravel.
Care is especially important if you live
in particular areas or operate your ve-
hicle under certain environmental condi-
tions:

Road salt or dust control chemicals will
accelerate corrosion, as will the pres-
ence of salt in the air near the sea±
coast or in areas of industrial pollution.

High humidity accelerates corrosion es-
pecially when temperatures range just
above the freezing point.

Wetness or dampness to certain parts
of your vehicle for an extended period
of time, may cause corrosion even
though other parts of the vehicle may
be dry.

High ambient temperatures can cause
corrosion to those components of the
vehicle which are prevented from
quick±drying due to lack of proper ven-
tilation.
The above signifies the necessity to keep
your vehicle, particularly the underside, as
clean as possible and to repair any dam-
age to paint or protective coatings as
soon as possible.
To help prevent corrosion on your
Toyota, follow these guidelines:
Wash your vehicle frequently. It is, of
course, necessary to keep your vehicle
clean by regular washing, but to prevent
corrosion, the following points should be
observed:

If you drive on salted roads in the
winter or if you live near the ocean,
you should hose off the undercarriage
at least once a month to minimize cor-
rosion.

High pressure water or steam is effec-
tive for cleaning the vehicle's underside
and wheel housings. Pay particular
attention to these areas as it is difficult
to see all the mud and dirt. It will do
more harm than good to simply wet the
mud and debris without removing them.
The lower edge of doors, rocker panels
and frame members have drain holes
which should not be allowed to clog
with dirt as trapped water in these
areas can cause corrosion.

Wash the underside of the vehicle thor-
oughly when winter is over.
See ªWashing and waxing your Toyotaº on
page 203 for more tips.
Check the condition of your vehicle's
paint and trim. If you find any chips or
scratches in the paint, touch them up im-
mediately to prevent corrosion from start-
ing. If the chips or scratches have gone
through the bare metal, have a qualified
body shop make the repair.

Cleaning the interior
CAUTION
Do not wash the vehicle floor with
water, or allow water to get onto the
floor when cleaning the vehicle interi-
or or exterior. Water may get into
audio components or other electrical
components above or under the floor
carpet (or mat) and cause a malfunc-
tion; and it may cause body corro-
sion.
Vinyl interior
The vinyl upholstery may be easily
cleaned with a mild soap or detergent
and water.
First vacuum over the upholstery to re-
move loose dirt. Then, using a sponge or
soft cloth, apply the soap solution to the
vinyl. After allowing it to soak in for a few
minutes to loosen the dirt, remove the dirt
and wipe off the soap with a clean damp
cloth. If all the dirt do not come off, re-
peat the procedure. Commercial foaming±
type vinyl cleaners are also available
which work well. Follow the manufacturer 's
instructions.
NOTICE
Do not use solvent, thinner, gasoline
or window cleaner on the interior.
Carpets
Use a good foam±type shampoo to
clean the carpets.
Begin by vacuuming thoroughly to remove
as much dirt as possible. Several types of
foam cleaners are available; some are in
aerosol cans and others are powders or
liquids which you mix with water to pro-
duce a foam. To shampoo the carpets,
use a sponge or brush to apply the foam.
Rub in overlapping circles.
Do not apply waterÐthe best results are
obtained by keeping the carpet as dry as
possible. Read the shampoo instructions
and follow them closely.
Seat belts
The seat belts may be cleaned with
mild soap and water or with lukewarm
water.
Use a cloth or sponge. As you are clean-
ing, check the belts for excessive wear,
fraying, or cuts.
NOTICE
Do not use dye or bleach on the
belts
Ðit may weaken them.
Do not use the belts until they be-
come dry.
Windows
The windows may be cleaned with any
household window cleaner.
NOTICE
When cleaning the inside of the rear
window, be careful not to scratch or
damage the heater wires or connec-
tors.
Air conditioning control panel, car au-
dio, instrument panel, console panel,
and switches
Use a soft damp cloth for cleaning.
Soak a clean soft cloth in water or luke-
warm water then lightly wipe off dirt.

Brake fluid level
Make sure the brake fluid level is correct.
See page 222 in Section 7±2 for addition-
al information.
Engine oil level
Check the level on the dipstick with the
engine turned off and the vehicle parked
on a level spot. See page 220 in Section
7±2 for additional information.
Power steering fluid level
Check the level through the reservoir. The
level should be in the ªHOTº or ªCOLDº
range depending on the fluid temperature.
See page 223 in Section 7±2 for addition-
al information.
Exhaust system
If you notice any change in the sound of
the exhaust or smell exhaust fumes, have
the cause located and corrected immedi-
ately. (See ªEngine exhaust cautionsº on
page 157 in Section 2.)Be on the alert for changes in perfor-
mance, sounds, and visual tip±offs that
indicate service is needed. Some impor-
tant clues are as follows:

Engine missing, stumbling, or pinging

Appreciable loss of power

Strange engine noises

A leak under the vehicle (however, wa-
ter dripping from the air conditioning
after use is normal.)

Change in exhaust sound (This may
indicate a dangerous carbon monoxide
leak. Drive with the windows open and
have the exhaust system checked im-
mediately.)

Flat±looking tire; excessive tire squeal
when cornering; uneven tire wear

Vehicle pulls to one side when driving
straight on a level road

Strange noises related to suspension
movement

Loss of brake effectiveness; spongy
feeling brake or clutch pedal; pedal al-
most touches floor; vehicle pulls to one
side when braking

Engine coolant temperature continually
higher than normalIf you notice any of these clues, take your
vehicle to your Toyota dealer as soon as
possible. It probably needs adjustment or
repair.
CAUTION
Do not continue driving with the ve-
hicle unchecked. It could result in se-
rious vehicle damage and possibly
personal injury.
