(f) Malfunction Indicator Lamp
This lamp warns that there is a problem
somewhere in your engine electrical sys-
tem.
If it comes on while you are driving, have
your vehicle checked/repaired by any au-
thorized Toyota dealer or repairer, or
another duly qualified and equipped pro-
fessional, as soon as possible.
On some models—
This lamp comes on in the following
cases.
a. There is a problem somewhere in your
engine, automatic transmission electri-
cal system or electronic throttle control
system.
b. The fuel tank is completely empty.
(See “Fuel gauge” on page 124 in this
Section for instructions.)
If it comes on while you are driving in
case a, have your vehicle checked/re-
paired by any authorized Toyota dealer or
repairer, or another duly qualified and
equipped professional, as soon as pos-
sible.
Vehicles with multi−mode manual transmis-
sion or vehicle stability control system—
If engine speed does not increase when
the accelerator pedal is depressed, there
may be a problem somewhere in the elec-
tronic throttle control system.
At this time, vibration may occur. Howev-
er, if you depress the accelerator pedal
more firmly and slowly, you can drive your
vehicle at low speeds. Have your Toyota
checked by any authorized Toyota dealer
or repairer, or another duly qualified and
equipped professional, as soon as pos-
sible.
Even if the abnormality of the electronic
throttle control system is corrected during
low speed driving, thesystem may not be
recovered until the engine is stopped and
the engine switch is turned to “ACC” or
“LOCK” position.CAUTION
Be especially careful to prevent erro-
neous pedal operation.
(g) “STOP” Warning Light
This light will come on when the engine
switch is turned to the “ON” position. After
a few seconds, the light will blink. When
the engine is started, the light will go off.
This means thesystem of the “STOP”
warning operating properly.
This light blinks in the following cases:
DWhen the engine coolant temperature
becomes high and the engine coolant
temperature warning light blinks. If the
engine coolant temperature rises fur-
ther, the engine coolant temperature
warning light remains on and at the
same time, the “STOP” warning light
blinks. In such cases, the engine is too
hot. If your vehicle overheats, stop the
vehicle and allow the engine to cool
down.
DWhen the engine oil pressure is too
low, the low engine oil pressure warn-
ing light comes on and at the same
time, the “STOP” warning light blinks.
In this case, pull off the road to a safe
place and stop the engine immediately.
Call any authorized Toyota dealer or re-
pairer, or another duly qualified and
equipped professional, for assistance.
(h) Low Fuel Level Warning Light and
Buzzer
The warning light blinks and the warning
buzzer comes on when the fuel level in
the tank becomes nearly empty. Fill up
the tank as soon as possible.
On incline or curves, due to the move-
ment of fuel in the fuel tank, the warning
light may blinks and the warning buzzer
may come on earlier than usual.

INFORMATION BEFORE DRIVING YOUR TOYOTA199
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.
DOil 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.
DOil 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.Oil consumption:Max. 1.0 L per 1000
km (1.1 qts./600 miles, 0.9 lmp.qts./600
miles)
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 has been excessively con-
sumed while 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 “Checking the engine oil level” on
page 264 in Section 7−2.

Facts about engine oil
consumption

STARTING AND DRIVING211
Before starting the engine, be sure to
follow the instructions in “(a) Before
cranking”.
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:
Multi−mode manual transmission:With
your foot off the accelerator pedal, turn
the engine switch to the “START” posi-
tion and crank the engine while depress-
ing the brake pedal. Release the key
when the engine starts. The engine can-
not be cranked if the shift lever is in a
position except “N” or the brake pedal
is not depressed.
Manual transmission:With your foot off
the accelerator pedal, crank the engine
by turning the engine switch to the
“START” position. Release it when the
engine starts.
Engine should be warmed up by driving,
not idling. For warming up drive with a
smoothly turning engine until the engine
coolant temperature is within the normal
range.
If the engine stalls...
Simply restart it, using the correct proce-
dure given in normal starting.
If the engine will not start...
See “If your vehicle will not start” on page
220 in Section 4.
NOTICE
zDo not crank for more than 30 se-
conds at a time. This may overheat
the starter and wiring systems.
zDo not race a cold engine.
zIf the engine becomes difficult to
start or stalls frequently, have the
engine checked immediately.
Pre−trip safety check
It is a good idea to do a safety check
before starting out on a trip. A few min-
utes of checking can help ensure safe and
pleasant driving. Just a basic familiarity
with your vehicle is required and a careful
eye! Or, if you would like, any authorized
Toyota dealer or repairer, or another duly
qualified and equipped professional, will
be pleased to make this check for you at
nominal cost.
CAUTION
If you make this check in an enclosed
garage, make sure there is adequate
ventilation. Engine exhaust is poison-
ous.
BEFORE STARTING THE ENGINE
Outside the vehicle
Tires.Check the pressure with a gauge
and look carefully for cuts, damage, or
excessive wear.
Wheel bolts.Make sure no bolts are mis-
sing or loose.
Fluid leaks.After the vehicle has been
parked for a while, check underneath for
leaking fuel, oil, water, or fluid. (Water
dripping from the air conditioning after use
is normal.)
Lights.Make sure the headlights, stop
lights, tail lights, turn signals and other
lights are all working. Check the headlight
aim.
Inside the vehicle
Spare tire, jack and wheel bolt wrench.
Check the spare tire pressure and make
sure you have your jack and wheel bolt
wrench.

Winter driving tips
Make sure your coolant is properly pro-
tected against freezing.
Only use “Toyota Super Long Life Coolant”
or similar high quality ethylene glycol
based non−silicate, non−amine, non−nitrite,
and non−borate coolant with long−life hy-
brid organic acid technology. (Coolant with
long−life hybrid organic acid technology is
a combination of low phosphates and or-
ganic acids.)
See “Checking the engine coolant level”
on page 267 in Section 7−2 for details of
coolant type selection.
“Toyota Super Long Life Coolant” is a mix-
ture of 50% coolant and 50% deionized
water. This coolant provides protection
down to about−35_C(−31_F).
NOTICE
Do not use plain water alone.
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. Any authorized Toyota
dealer or repairer, or another duly quali-
fied and equipped professional, will be
pleased to check the level of charge.
Make sure the engine oil viscosity is
suitable for the cold weather.
See page 264 in Section 7−2forrecom-
mended viscosity. Leaving a heavy sum-
mer oil in your vehicle during winter
months may make starting harder. If you
are not sure about which oil to use, call
any authorized Toyota dealer or repairer,
or another duly qualified and equipped
professional, they 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.Use a washer fluid containing an anti-
freeze solution.
This product is available at any authorized
Toyota dealer or repairer and most auto
parts stores or another qualified profes-
sional. Follow the manufacturer ’s direc-
tions for how much to mix with water.
NOTICE
Do not use engine antifreeze or any
other substitute because it may dam-
age your vehicle’s paint.
Do not use your parking brake when
there is a possibility it could freeze.
When parking, put the transmission into
“M(1)”, “E(1)” or “R” (multi−mode manual
transmission), or into first or reverse
(manual transmission) and block the rear
wheels. Do not use the parking brake,
snow or water 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.
Depending on where you are driving,
we recommend you carry some emer-
gency equipment.
Some of the things you might put in the
vehicle are tire chains, a window scraper,
a bag of sand or salt, flares, a small
shovel, jumper cables, etc.

IN CASE OF AN EMERGENCY225
If engine speed does not increase when
the accelerator pedal is depressed, there
may be a problem somewhere in the elec-
tronic throttle control system.
At this time, vibration may occur. Howev-
er, if you depress the accelerator pedal
more firmly and slowly, you can drive your
vehicle at low speeds. Have your Toyota
checked by any authorized Toyota dealer
or repairer, or another duly qualified and
equipped professional, as soon as pos-
sible.
Even if the abnormality of the electronic
throttle control system is corrected during
low speed driving, thesystem may not be
recovered until the engine is stopped and
the engine switch is turned to “ACC” or
“LOCK” position.
CAUTION
Be especially careful to prevent erro-
neous pedal operation.
If your high engine coolant temperature
warning light flashes to indicates over-
heating, if you experience a loss of
power, or if you hear a loud knocking
or pinging noise, the engine has prob-
ably 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 “N”
(multi−mode manual transmission), or
neutral (manual transmission) 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 engine switch 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.

260DO−IT−YOURSELF MAINTENANCE: Introduction
If you perform maintenance by yourself,
be sure to follow the correct procedure
given in this Section.
You should be aware that improper or in-
complete servicing may result in operating
problems.
This Section gives instructions only for
those items that are relatively easy for an
owner to perform. As explained in Section
6, there are still a number of items that
must be done by a qualified technician
with special tools.
Utmost care should be taken when work-
ing on your vehicle to prevent accidental
injury. Here are a few precautions that
you should be especially careful to ob-
serve:
CAUTION
DWhen the engine is running, keep
hands, clothing, and tools away
from the moving fan and engine
drive belts. (Removing rings,
watches, and ties is advisable.)
DRight after driving, the engine
compartment—the engine, radiator,
exhaust manifold, and spark plug
boots, etc. —will be hot. So be
careful not to touch them. Oil,
fluids and spark plugs may also be
hot.
DIf the engine is hot, do not remove
the radiator cap or coolant reser-
voir cap or loosen the drain plugs,
to prevent burning yourself.
DDo not leave anything that may
burn easily, such as paper or rags,
in the engine compartment.
DDo not smoke, cause sparks or al-
low open flames around fuel or the
battery. Their fumes are flammable.
DBe extremely cautious when work-
ing on the battery. It contains poi-
sonous and corrosive sulfuric acid.
DDo not get under your vehicle with
just the body jack supporting it. Al-
ways use automotive jack stands or
other solid supports.
DBe sure that the engine is off if you
work near the electric cooling fan
or radiator grille. With the engine
on, the electric cooling fan will au-
tomatically start to run if the en-
gine coolant temperature is high
and/or the air conditioning is on.
DUse eye protection whenever you
work on or under your vehicle
where you may be exposed to flying
or falling material, fluid spray, etc.
DUsed engine oil contains potentially
harmful contaminants which may
cause skin disorders such as in-
flammation or skin cancer, so care
should be taken to avoid prolonged
and repeated contact with it. To re-
move used engine oil from your
skin, wash thoroughly with soap
and water.
DDo not leave used oil within the
reach of children.
DDispose of used oil and filter only
in a safe and acceptable manner.
Do not dispose of used oil and fil-
ter in household trash, in sewers or
onto the ground. Call your dealer or
a service station for information
concerning recycling or disposal.
DTake care when filling the brake
fluid reservoir because brake fluid
can harm your hands or eyes. If
fluid gets on your hands or in your
eyes, flush the affected area with
clean water immediately. If you still
feel uncomfortable with your hands
or eyes, go to the doctor.

DO−IT−YOURSELF MAINTENANCE: Engine and Chassis265
ENGINE OIL SELECTION
Your Toyota vehicle is filled with “Toyota
Genuine Motor Oil” at the factory. Toyota
recommends the use of approved “Toyota
Genuine Motor Oil”. Another motor oil of
matching quality can also be used.
Oil grade:
0W−20, 5W−20, 5W−30 and10W−30:
API grade SL “Energy−Conserving”,
SM “Energy−Conserving” or ILSAC
multigrade engine oil
15W−40 and 20W−50:
API grade SL or SM multigrade engine
oil
Recommended viscosity (SAE):
SOIL35
Temperature range anticipated before
next oil change.
Preferred
SAE 0W−20 is filled into your Toyota
vehicle at manufacturing, and the best
choice for good fuel economy and good
starting in cold weather.
If SAE 0W−20 oil is not available, SAE
5W−30 oil may be used. However, it
should be replaced with SAE 0W−20 at
the next oil change.
If you use SAE10W−30 or a higher
viscosity engine oil in extremely low
temperatures, the engine may become
difficult to start, so SAE 5W−30 or low-
er viscosity engine oil is recommended.
The 0W portion of the oil viscosity rating
indicates the characteristic of the oil which
allows cold startability. Oils with a lower
value before the W allow for easier
starting of the engine in cold weather.
The20in0W−20 indicates the oil
viscosity when the oil is at its operating
temperature. An oil with a higher viscosity
may be better suited if the vehicle is
operated at high speeds, or under extreme
load conditions.
