Inserting inappropriate or badly fit-
ting plugs into the power outlet.
NOTICE
To prevent the battery from being
discharged, turn off all the vehicle’s
electronic equipment and accesso-
ries, such as the headlights, fog
lights and air conditioning, when
electrical appliances that consume
in excess of 100W are used contin-
uously for long periods of time.
 To prevent any damage caused by
heat, do not use any electrical ap-
pliances that give off intense heat
such as toasters, in any locations
including the internal or external
trim, seats and deck.
 Do not use any electrical ap-
pliances, which are easily affected
by vibration or heat, inside the ve-
hicle. Vibration while driving, or the
heat of the sun while parking, may
result in damage to those electrical
appliances.
Keep the lid closed when the power
outlet is not in use. Do not insert
any items other than appropriate
plugs, as this may cause electrical
failure or short circuits.
 After inserting a plug, gently close
the power outlet lid. Failure to do
so may cause damage to the plug.
 If any electrical appliances are to
be used while driving, securely fas-
ten both the appliances and their
cables to prevent them from falling
or getting caught any of the power-
train components.
 Do not use plug adaptors to con-
nect too many plugs to the power
outlet.
 If the power outlet is loose when an
electrical appliance plug is con-
nected, replace the outlet. Contact
a Toyota dealer for any necessary
replacements.If the power outlet gets dirty, turn
the main switch off and use a soft,
clean, drywet cloth to wipe it gent-
ly. Do not use any cleansing materi-
als, such as organic solvents, wax,
or compound cleaners, as these
may damage the power outlet or
cause it to malfunction.
 Keep the power outlet free from
dust and foreign materials and
clean it regularly.
The power outlet is not designed for
the following electric appliances even
though their power consumption is un-
der 115 VAC/100W. These appliances
may not operate properly.
Appliances with high initial peak watt-
age: cathode− ray tube type televisions,
compressor −driven refrigerators, electric
pumps, electric tools, etc.
Measuring devices which process pre-
cise data: medical equipment, measur-
ing instruments, etc.
Other appliances requiring an extremely
stable power supply: microcomputer −
controlled electric blankets, touch sen-
sor lamps, etc.

In order to maintain engine braking effi-
ciency when driving on a long steep
downgrade, do not use the transmis-
sion in “D”. Select an appropriate shift
range in “S” mode (See “Automatic
transmission” on page 211 in Section
1−7).
Because of the added load of the trail-
er, your vehicle’s engine may overheat
on hot days (at temperatures over
30 C [85 F]) when going up a long or
steep grade with a trailer. If the engine
coolant temperature gauge indicates
overheating, immediately turn off the air
conditioning (if in use), pull off the road
and stop in a safe spot. Refer to “If
your vehicle overheats” on page 502 in
Section 4.
Always place wheel blocks under both
the vehicle and trailer wheels when
parking. Apply the parking brake firmly.
Put the transmission in “P”. Avoid park-
ing on a slope with a trailer, but if it
cannot be avoided, do so only after
performing the following:
1. Apply the brakes and hold.
2. Have someone place wheel blocks un- der both the vehicle and trailer wheels.
3. When the wheel blocks are in place, release your brakes slowly until the
blocks absorb the load.
4. Apply the parking brake firmly.
5. Shift into “P” and turn off the engine.
When restarting out after parking on a
slope: 1. With the transmission in “P” position, start the engine. Be sure to keep the
brake pedal depressed.
2. Shift into gear.
3. Release the parking brake and brake pedal, and slowly pull or back away
from the wheel blo cks. Stop and apply
your brakes.
4. Have someone retrieve the blo cks.CAUTION
Do not use cruise control when you
are towing down long, steep grades
or with heavy loads.
Slow down and downshift before
descending steep or long downhill
grades. Do not make sudden down-
shifts.
Avoid holding the brake pedal down
too long or too frequently. This
could cause the brakes to overheat
and result in reduced braking effi-
ciency.

If your engine stalls while driving...
1. Reduce your speed gradually, keeping a straight line. Move cautiously off the
road to a safe place.
2. Turn on your emergency flashers.
3. Turn the engine switch to the “ACC” or “LOCK” position, and try starting the
engine again.
If the engine will not start, see “If your
vehicle will not start” on page 498 in this
Section.
CAUTION
If the engine is not running, the pow-
er assist for the brakes and steering
will not work so steering and braking
will be much harder than usual.
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 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 engine switch is turned to the “ACC”
or “LOCK” position.
CAUTION
Be especially careful to prevent erro-
neous pedal operation.
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 “P”
and apply 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.
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. Visually check to see if the engine
drive belt (fan belt) is broken or loose.
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.
4. If the engine drive belt is broken or thecoolant is leaking, stop the engine im-
mediately. Call a Toyota dealer for as-
sistance.
5. If the engine drive belt is O.K. and there are no obvious leaks, you may
help the engine cool down more quickly
by running it at about 1500 rpm for a
few minutes with the accelerator pedal
lightly depressed.
6. Check the coolant reservoir. If it is dry, add coolant to the reservoir while the
engine is running. Fill it about half full.
For the coolant type, See “Coolant type
selection” on page 551 in Section 7 −2.
CAUTION
Do not attempt to remove the radiator
cap when the engine and radiator are
hot. Serious injury could result from
scalding hot fluid and steam blown
out under pressure.
7. After the engine coolant temperature
has cooled to normal, again check the
coolant level in the reservoir. If neces-
sary, bring it up to half full again. Seri-
ous coolant loss indicates a leak in the
system. You should have it checked as
soon as possible at your Toyota dealer.
1. Reduce your speed gradually, keeping a straight line. Move cau-
tiously off the road to a safe place
well away from the traffic. Avoid
stopping on the center divider of
a highway. Park on a level spot
with firm ground.
2. Stop the engine and turn on your emergency flashers.
3. With the transmission in “P” firmly set the parking brake.
4. Have everyone get out of the ve- hicle on the side away from traffic.
5. Read the following instructions thoroughly.
If you have a flat tire—

Do not apply water—the best results are
obtained by keeping the carpet as dry as
possible. Read the shampoo instructions
and follow them closely.
Seat belts
The seat belts may be cleaned with
mild soap and water or with lukewarm
water.
Use a cloth or sponge. As you are clean-
ing, check the belts for excessive wear,
fraying, or cuts.
NOTICE
Do not use dye or bleach on the
belts—it may weaken them.
 Do not use the belts until they be-
come dry.
Windows
The windows may be cleaned with any
household window cleaner.
Air conditioning control panel, audio
panel, 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 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.
 Mildew may develop on soiled leath-
er upholstery. Be especially careful
to avoid oil spots. Try to keep your
upholstery always clean.
 Long exposure to direct sunlight
may cause the leather surface to
harden and shrink. Keep your ve-
hicle in a shaded area, especially in
the summer.

Doors and engine hood
Check that all doors including tailgate op-
erate smoothly and all latches lock se-
curely. Make sure the engine hood sec-
ondary latch secures the hood from
opening when the primary latch is re-
leased.
Tire inflation pressure
Check the pressure with a gauge ev-
ery two weeks, or at least once a
month. See page 553 in Section 7 −2
for additional information.
Tire surface and wheel nuts
Check the tires carefully for cuts,
damage or excessive wear. See page
556 in Section 7− 2 for additional in-
formation. When checking the tires,
make sure no nuts are missing, and
check the nuts for looseness. Tighten
them if necessary. Tire rotation
Rotate the tires
according to the
maintenance schedule. (For
scheduled maintenance information,
please refer to the “Scheduled
Maintenance Guide” or “Owner ’s
Manual Supplement”.) See page 558
in Section 7 −2 for additional
information.
Be on the alert for changes in perfor-
mance, sounds, and visual tip −offs 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.)
Flat −looking 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 normal
Does your vehicle need
repairing?
