It is not a malfunction even if the needle
of the engine coolant temperature gauge
returns to “C” when the ignition switch is
turned to the “START” position.
NOTICE
Do not remove the thermostat in
the engine cooling system as this
may cause the engine to overheat.
The thermostat is designed to con-
trol the flow of coolant to keep the
temperature of the engine within
the specified operating range.
 Do not continue driving with an
overheated engine. See “If your ve-
hicle overheats” on page 255.
Engine oil pressure gauge
Idling
Normal
driving
The engine oil pressure gauge indicates
engine oil pressure when the ignition
switch is on. Check it while driving to
make sure the needle is in the proper
range.
If the engine oil pressure should stay be-
low the normal range, pull off the road to
a safe place and stop the engine immedi-
ately. Call a Toyota dealer or qualified
repair shop for assistance.
Engine oil pressure may not build up
when the engine oil level is too low. The
engine oil pressure gauge is not designed
to indicate oil level, and the engine oil
level must be checked using the level
dipstick. It is not a malfunction even if the needle
of the engine oil pressure gauge returns
to “L” when the ignition switch is turned
to the “START” position.
NOTICE
Do not drive the vehicle with the en-
gine oil pressure below the normal
range until the cause is fixed—it may
ruin the engine.

(b) Driver’s Seat Belt Reminder Lightand Buzzer
This light and buzzer remind you to
buckle up the driver’s seat belt.
Once the ignition key is turned to “ON” or
“START”, the reminder light flashes and
the buzzer sounds if the driver ’s seat belt
is not fastened. Unless the driver fastens
the belt, the light keeps on flashing and
the buzzer sounds 4 to 8 seconds.
(c) Front Passenger ’s Seat Belt Re- minder Light
This light reminds you to buckle up the
front passenger ’s seat belt.
Once the ignition key is turned to “ON” or
“START”, the reminder light flashes if a
passenger sits in the front passenger seat
and does not fasten the seat belt. Unless
the front passenger fastens the belt, the
light stays flashing.
If luggage or other load is placed on the
front passenger seat, depending on its
weight and how it is placed on the seat,
built −in sensors in the seat cushion may
detect the pressure, causing the reminder
light to come on. (d) Discharge Warning Light
This light warns that the battery is being
discharged.
If it comes on while you are driving, there
is a problem somewhere in the charging
system.
The engine ignition will continue to oper-
ate, however, until the battery is dis-
charged. Turn off the air conditioning,
blower, radio, etc., and drive directly to
the nearest Toyota dealer or repair shop.
NOTICE
Do not continue driving if the engine
drive belt is broken or loose.
(e) Engine Oil Replacement Reminder
Light
This light reminds you when to replace
the engine oil.
This light will come on when the ignition
switch is turned to “ON”, and will go off
after about a few seconds. When you drive for about 7200 km (4500
miles) after engine oil replacement, this
light illuminates for about 3 seconds and
then flashes for about 12 seconds with
the ignition key is turned to “ON” position.
If you continue driving without engine oil
replacement, and if the driving range ex-
ceeds 8000 km (5000 miles), the light will
come on after the ignition key is turned
to “ON” position. The light will remain on
thereafter.
If the light is flashing, we recommend that
you replace the engine oil at an early
opportunity depending on the driving and
road condition. If the light comes on, re-
place it as soon as possible.
You need to reset the light after the en-
gine oil replacement. Reset the light by
following the procedure below:
1. Turn the ignition key to the “OFF” posi- tion
with the odometer reading shown.
(For details, see “Odometer and trip me-
ter” on page 125).
2. Turn the ignition key to the “ON” posi- tion while holding down the “ODO/
TRIP” knob.
Hold down the knob until the light goes
off. Before the light goes off, it illuminates
for 3 seconds, flashes for 2 seconds, illu-
minates for 1 second.

“START”—Starter motor on. The key
will return to the “ON” position when
released.
For starting tips, see page 235.
It is not a malfunction even if the needle
of the tachometer, fuel gauge, engine
coolant temperature gauge, engine oil
pressure gauge or voltmeter returns to
bottom position when the ignition switch is
turned to the “START” position.
“ON”—Engine on and all accessories
on.
This is the normal driving position.“ACC”—Accessories such as the radio
operate, but the engine is off.
If you leave the key in the “ACC” or
“LOCK” position and open the driver’s
door, a buzzer will remind you to remove
the key.
“LOCK”—Engine is off and the steering
wheel is locked. The key can be re-
moved only at this position.
To turn the key from “ACC” to the “LOCK”
position, you must put the selector lever
in the “P” position.
Once you remove the key, the engine im-
mobilizer system is automatically set. (See
“Engine immobilizer system” on page 12.)
When starting the engine, the key may
seem stuck at the “LOCK” position. To
free it, first be sure the key is pushed all
the way in, and then rock the steering
wheel slightly while turning the key gently.
NOTICE
Do not leave the key in the “ON”
position if the engine is not running.
The battery will discharge and the
electronic ignition system could be
damaged.

Keep the back door and quarter
windows closed while driving. An
open or unsealed back door and
quarter windows may cause ex-
haust gases to be drawn into the
vehicle.
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 win-
dows open and the back door
closed. Have the cause immedi-
ately located and corrected.
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.
Oil consumption: Max. 1.0 L per 1000
km (1.1 qt./600 miles, 0.9 Imp.qt/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.

Improving fuel economy is easy–just 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 page on
299.
Do not carry unneeded weight in
your vehicle. Excess weight puts a
heavier load on the engine, causing
greater fuel consumption.
Avoid lengthy warmup idling. Once
the engine is running smoothly, begin
driving—but gently. Remember, howev-
er, that on cold winter days this may
take a little longer.
Accelerate slowly and smoothly.
Avoid jackrabbit starts.
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 over-revving. 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 dis-
tance from other vehicles to avoid sud-
den braking. This will also reduce wear
on your brakes.
Avoid heavy traffic or traffic jams
whenever possible.
Do not rest your foot on the brake
pedal. This causes premature wear,
overheating and poor fuel economy.
Maintain a moderate speed on high-
ways. The faster you drive, the greater
the fuel consumption. By reducing your
speed, you will cut down on fuel con-
sumption.
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 tunedup 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 con-
tribute 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 “Scheduled
Maintenance Guide” or “Owner ’s Manu-
al Supplement”.)
