Air flow selector settingsOperating tips
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 seats clear to
allow air to circulate throughout the ve-
hicle.
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”.

If following another vehicle on a dusty
road, or driving in windy and dusty
conditions, it is recommended that the
air intake selector be temporarily set to
RECIRCULATE, which will close off the
outside passage and prevent outside
air and dust from entering the vehicle
interior.Heating
For best results, set controls to:
Fan speed— Any setting except “OFF”
Temperature— To w a r d s WARM
(red zone)
Air intake—FRESH (outside air)

If the engine speed does not increase with
the accelerator pedal depressed down to
about the middle position, there may be
a problem somewhere in your electronic
throttle control system.
At this time, if you depress the accelera-
tor pedal more firmly and slowly, you can
drive you vehicle at low speeds. Have
your vehicle checked by your Toyota deal-
er 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.
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 “N”
(sequential manual transmission) or in
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 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 theradiator, 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 coolant
reservoir cap or air release valve
when the engine and radiator are hot.
Serious injury could result from
scalding hot fluid and steam blown
out under pressure.

household window cleaner.
NOTICE
When cleaning the inside of the win-
dow, 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 any dirt.
NOTICE
Do not use organic substances (sol-
vents, kerosene, alcohol, gasoline,
etc.) or alkaline or acidic solutions.
These chemicals can cause discol-
oring, staining or peeling of the
surface.
 If you use cleaners or polishing
agents, make sure their ingredients
do not include the substances men-
tioned above.
 If you use a liquid car freshener, do
not spill the liquid onto the ve-
hicle’s interior surfaces. It may con-
tain the ingredients mentioned
above. Immediately clean any spill
using the method mentioned above.
Leather Interior
The leather upholstery may be cleaned
with neutral detergent for wool.
Remove dirt using a soft cloth dampened
with 5% solution of neutral detergent for
wool. Then thoroughly wipe off all traces
of detergent with a clean damp cloth.
After cleaning or whenever any part of the
leather gets wet, dry with a soft clean
cloth. Allow the leather to dry in a venti-
lated shaded area.
NOTICE
If a stain should fail to come out
with a neutral detergent, apply a
cleaner that does not contain an
organic solvent.
 Never use organic substances such
as benzine, alcohol or gasoline, or
alkaline or acid solutions for clean-
ing the leather as these could
cause discoloring.
 Use of a nylon brush or synthetic
fiber cloth, etc. may scratch the
fine grained surface of the leather.

Be on the alert for changes in perfor-
mance, sounds, and visual tipoffs 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.)
Flatlooking 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.
Some states have vehicle emission in-
spection programs which include OBD
(OnBoard Diagnostics) che
cks.
The OBD system monitors the operation
of the emission control system. When the
OBD system determines that a problem
exists somewhere in the emission control
system, the malfunction indicator lamp
comes on. In this case, your vehicle may
not pass the I/M test and need to be
repaired. Contact your Toyota dealer to
service the vehicle.
Even if the malfunction indicator lamp
does not come on, your vehicle may not
pass the I/M test as readiness codes
have not been set in the OBD system.
Readiness codes are automatically set
during ordinary driving. However, when the
battery is disconnected or run down, the
codes are erased. Also, depending on
your driving habits, the codes may not be
completely set.
Also, if the malfunction indicator lamp had
come on recently due to temporary mal-
function such as a loose fuel tank cap,
your vehicle may not pass the I/M test.

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.
Performing doityourself maintenance
during the warranty period may affect your
warranty coverage. Read the separate
Toyota Warranty statement for details and
suggestions.
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.
For information on tools and parts for do
ityourself maintenance, see “Parts and
tools” on page 203.
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
When 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.)
Right after driving, the engine
compartment and trunk room—the
engine, radiator, exhaust manifold,
power steering fluid reservoir and
spark plug boots, etc.—will be hot.
So be careful not to touch them.
Oil, fluids and spark plugs may also
be hot.
If the engine is hot, do not remove
the coolant reservoir cap or air re-
lease valve or loosen the drain
plugs to prevent burning yourself.
Do not smoke, cause sparks or al-
low open flames around fuel or the
battery. Their fumes are flammable.
Do not get under your vehicle with
just the body jack supporting it. Al-
ways use automotive jack stands or
other solid supports.
Be sure that the ignition is off if
you work near the electric cooling
fans or radiator grille. With the
ignition on, the electric cooling fans
will automatically start to run if the
engine coolant temperature is high
and/or the air conditioning is on.
Use eye protection whenever you
work on or under your vehicle
where you may be exposed to flying
or falling material, fluid spray, etc.
Be extremely cautious when work-
ing on the battery. It contains poi-
sonous and corrosive sulfuric acid.
Warning: Battery posts, terminals
and related accessories contain lead
and lead compounds, chemicals
known to the State of California to
cause cancer and reproductive
harm. Wash hands after handling
Used 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.
