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 332 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.

(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) Malfunction Indicator Lamp
This lamp comes on when the ignition
key is turned to the “ON” position and
goes off after the engine starts. This
means that the warning light system is
operating properly.
If the lamp remains on or the lamp
comes on while driving, first check the
followings.
Empty fuel tank
If the fuel tank is empty, refuel immedi-
ately.
Loose fuel tank cap
If the fuel tank cap is loose, securely
tighten it.
These cases are temporary malfunctions.
The malfunction indicator lamp will go off
after taking several driving trips.
If the lamp will not go off even after the
several trips, contact your Toyota dealer
as soon as possible.
If the fuel tank is not empty or the fuel
tank cap is not loose...
There is a problem somewhere in the
engine, emission control system, elec-
tronic throttle control system, automatic
transmission electrical system or warn-
ing light system itself.
Contact your Toyota dealer as soon as
possible to service the vehicle.
If the engine speed does not increase with
the accelerator pedal depressed down,
there may be a problem somewhere in
your electronic 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 vehicle
checked by your Toyota dealer as soon as
possible. Even if the abnormality of the electronic
throttle control system is corrected during
low speed driving, the system may not be
recovered until the engine is stopped and
the ignition key is turned to “ACC” or
“LOCK” position.
CAUTION
Be especially careful to prevent erro-
neous pedal operation.
Emissions inspection and maintenance
(I/M) programs
We recommend you to contact your
Toyota dealer to check your vehicle’s
emission control system and OBD
(On
−Board Diagnostics) system before
taking your vehicle for a state emission
inspection.
For details, see “Emissions Inspection and
Maintenance (I/M) programs” on page 362
in Section 6.

Avoid using cassettes with a total play-
ing time longer than 100 minutes (50
minutes per side). The tape used in
these cassettes is thin and could get
stuck or tangled in the cassette player.
CARING FOR YOUR COMPACT DISC
PLAYER, DVD PLAYER AND DISCS
Your compact disc player and DVD
player are intended for use with 12 cm
(4.7 in.) discs only.
Extremely high temperatures can keep
your compact disc player and DVD
player from working. On hot days, use
the air conditioning to cool the vehicle
interior before you use the players.
Bumpy roads or other vibrations may
make your compact disc player and
DVD player skip.
If moisture gets into your compact disc
player and DVD player, the players
may not play even though they appear
to be working. Remove the disc from
the player and wait until it dries.
CAUTION
Compact disc players and DVD play-
ers use an invisible laser beam which
could cause hazardous radiation ex-
posure if directed outside the unit. Be
sure to operate the players correctly.

“AUTO” button
For automatic operation of the air condi-
tioning, press the “AUTO” button. An indi-
cator light will illuminate to show that the
automatic operation mode has been se-
lected.
In the automatic operation mode, the air
conditioning selects the most suitable fan
speed and air flow, on−off of the air condi-
tioning and air intake according to the
temperature.
When you press the “AUTO” button with
the air intake mode at FRESH, internal
circulation may be applied for maximum
cooling.
When you adjust the temperature selector
to maximum cooling, a “MAX COLD” mes-
sage will appear on the display and the
air intake mode will be automatically
changed to RECIRCULATE.
You may use manual controls if you want
to select your own settings. Fan speed selector
Turn the knob to adjust the fan speed—to
the right to increase, to the left to de-
crease.
In automatic operation, the fan speed is
adjusted automatically unless you desire
another fan speed mode.
Temperature selector
Turn the knob to adjust the temperatu-
re—to the right to warm, to the left to
cool.
The temperature display changes between
“
 C” and “ F” when the unit of the outside
temperature display is changed. (For de-
tails, see “Multi −information display” on
page 256 in Section 1 −10.)
“OFF” button
Push the button to turn off the air condi-
tioning system.
“MODE” button (air flow selector)
Press the button to select the vents used
for air flow.
In automatic operation, the air flow mode
is selected automatically among Panel, Bi −
level and Floor unless you desire another
air flow mode.
1. Panel— Air flows mainly from the
instrument panel vents.

Air intake selector
Press the button to select the air source.1. RECIRCULATE— Recirculates the air in-
side the vehicle.
2. FRESH— Draws outside air into the
system.
To prevent fogging up of the windshield,
the air intake mode may change automati-
cally to FRESH depending on the condi-
tion of the air conditioning system.
For example, when the ambient tempera-
ture is low, the air intake mode may
change automatically to FRESH. This is
not a malfunction. “A/C” button
To turn on the air conditioning, press the
“A/C” button. The “A/C” button indicator
will come on. To turn the air conditioning
off, press the button again.
If the “A/C” button indicator flashes, there
is a problem in the air conditioning system
and the air conditioning automatically
shuts off. If this happens, take your ve-
hicle to a Toyota dealer for service.

To cool off your Toyota after it has
been parked in the hot sun, drive with
the windows open for a few minutes.
This vents the hot air, allowing the air
conditioning to cool the interior more
quickly.
Make sure the air intake grilles in front
of the windshield are not blocked (by
leaves or snow, for example).
On humid days, do not blow cold air
on the windshield. The windshield could
fog up because of the difference in air
temperature on the inside and outside
of the windshield.
Keep the area under the front seats
clear to allow air to circulate through-
out the vehicle.
On cold days, set the fan speed to
high for a minute to help clear the
intake ducts of snow or moisture. This
can reduce the amount of fogging on
the windows.
When driving on dusty roads, close all
windows. If dust thrown up by the ve-
hicle is still drawn into the vehicle after
closing the windows, it is recommended
that the air intake selector be set to
FRESH and the fan speed selector to
any setting except “OFF”.
