Idling for a long period with the air
conditioning on in stop−and− go traffic.
Towing a trailer.
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 388 in
Section 4.
Normal
driving
Idling
The oil pressure gauge indicates engine
oil pressure when the ignition switch is
on. Check it while driving to make sure
that the needle is in the proper range.
If the oil pressure should stay below the
normal range, pull off the road to a safe
place and stop the engine immediately.
Call a Toyota dealer or qualified repair
shop for assistance.
Oil pressure may not build up when the
oil level is too low. The oil pressure
gauge is not designed to indicate oil level,
and the oil level must be checked using
the level dipstick.
NOTICE
Do not drive the vehicle with the oil
pressure below the normal range until
the cause is fixed—it may ruin the
engine.

(l) Low Tire Pressure Warning Light
This light warns that the tire pressure of
one or more of your tires (including the
spare tire) is low. The light comes on
when the ignition key is turned to the
“ON” position. It goes off after a few sec-
onds. This indicates that the tire pressure
warning system is functioning properly.
If the warning light comes on, stop your
vehicle in a safe place as soon as pos-
sible and check that the inflation pressure
of all tires (including the spare tire) is as
specified on the tire and loading informa-
tion label. (See “Checking tire inflation
pressure” on page 431 in Section 7−2.)
The light should go off a few minutes after
the tire pressure is adjusted.
If the warning light blinks, the tire pres-
sure warning system may be malfunction-
ing. Contact your Toyota dealer.
For details, see “Tire pressure warning
system” on page 198 in Section 1 −7.
(m) Low Windshield Washer Fluid Level Warning Light
This light warns that the windshield wash-
er fluid level is too low. Add washer fluid
at your earliest opportunity. (For instruc-
tions, see “Adding washer fluid” on page
446 in Section 7 −3.) (n) Engine Oil Replacement Reminder
Light (for vehicles sold in U.S.A.)
This light acts as a reminder to replace
the engine oil.
This light will come on when the ignition
key is turned to “ON” and will go off after
about a few seconds.
When you drive for about 7200 km (4500
miles) after the engine oil replacement,
this light illuminates for about 3 seconds
and then flashes for about 12 seconds
with the ignition key turned to the “ON”
position. If you continue driving without
replacing the engine oil, and if the dis-
tance driven exceeds 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 conditions. If the light comes on,
replace it as soon as possible. The system must be reset after the en-
gine oil replacement. Reset the system by
the following procedure:
1. Turn the ignition key to the “ACC” or “LOCK” position with the odometer
reading shown. (For details, see
“Odometer and two trip meters” on
page 160 in this Section.)
2. Turn the ignition key to the “ON” posi- tion while holding down the trip meter
reset knob.
Hold down the knob for at least 5 sec-
onds. The odometer indicates “000000”
and the light goes off.
If the system fails to reset, the light will
continue flashing.
(o) Key Reminder Buzzer
This buzzer acts as a reminder to remove
the key when you open the driver’s door
with the ignition key in the “ACC” or
“LOCK” position.

CHECKING SERVICE REMINDER
INDICATORS (except the low fuel level
warning light and low windshield
washer fluid level warning light)1. Apply the parking brake.
2. Open one of the side doors or back door.
The open door warning light should
come on.
3. Close the door. The open door warning light should go
off.
4. Turn the ignition key to “ON”, but do not start the engine.
All the service reminder indicators ex-
cept the open door warning light should
come on. The “ABS” and “VSC TRAC”
warning lights, low tire pressure warn-
ing light and engine oil replacement
reminder light go off after a few sec-
onds. The SRS warning light goes off
after about 6 seconds. (The “TRAC
OFF” (two −wheel drive models) or
“VSC OFF” (four −wheel drive models),
“RSCA OFF” indicator lights, height
control indicator light, manual control
mode indicator light and slip indicator
light also come on and go off after a
few seconds.) If any service reminder indicator or warn-
ing buzzer does not function as described
above, have it checked by your Toyota
dealer as soon as possible.

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 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 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 back door and back win-
dow closed while driving. An open
or unsealed back door and back
window, may cause exhaust 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 wind-
shield clear of snow, leaves, or oth-
er obstructions.
If you smell exhaust fumes in the
vehicle, drive with the windows
open and the back door and back
window closed. Have the cause im-
mediately 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.
