Drive gently and avoid high speeds.
Your vehicle does not need an elaborate
break−in. But following a few simple tips
for the first 1600 km (1000 miles) can add
to the future economy and long life of
your vehicle:
Avoid full throttle acceleration when
starting and driving.
Avoid racing the engine.
Try to avoid hard stops during the first
300 km (200 miles).
Do not drive for a long time at any
single speed, either fast or slow.
Do not tow a trailer during the first 800
km (500 miles). FUEL TYPE
Your new vehicle must use only un-
leaded gasoline.
To help prevent gas station mix
−ups, your
Toyota has a smaller fuel tank opening.
The special nozzle on pumps with un-
leaded fuel will fit it, but the larger stan-
dard nozzle on pumps with leaded gas will
not.
At a minimum, the gasoline you use
should meet the specifications of ASTM
D4814 in the U.S.A. and CGSB 3.5 −M93
in Canada.NOTICE
Do not use leaded gasoline. Use of
leaded gasoline will cause the three
way catalytic converter to lose its ef-
fectiveness and the emission control
system to function improperly. Also,
this can increase maintenance costs.
OCTANE RATING
Select Octane Rating 87 (Research
Octane Number 91) or higher. For
improved vehicle performance, use
premium unleaded gasoline with an
Octane Rating of 91 (Research Octane
Number 96) or higher.
Use of unleaded gasoline with an octane
rating or research octane number lower
than stated above will cause persistent
heavy knocking. If it is severe, this will
lead to engine damage.
If your engine knocks...
If you detect heavy knocking even when
using the recommended fuel, or if you
hear steady knocking while holding a
steady speed on level roads, consult your
Toyota dealer.
However, occasionally, you may notice
light knocking for a short time while accel-
erating or driving up hills. This is normal
and there is no need for concern.

GASOLINE CONTAINING DETERGENT
ADDITIVES
Toyota recommends the use of gasoline
that contains detergent additives to
avoid buildup of engine deposits.
However, all gasoline sold in the U.S.
contains detergent additives to keep clean
and/or clean intake systems.
QUALITY GASOLINE
Automotive manufacturers in the U.S.,
Europe and Japan have developed a
specification for quality fuel named
WorldWide Fuel Charter (WWFC) that
is expected to be applied world wide.
The WWFC consists of four categories
that depend on required emission lev-
els. In the U.S., category 4 has been
adopted. The WWFC improves air quali-
ty by providing for better emissions in
vehicle fleets, and customer satisfaction
through better vehicle performance.CLEANER BURNING GASOLINE
Cleaner burning gasoline, including re-
formulated gasoline that contains oxy-
genates such as ethanol or MTBE is
available in many areas.
Toyota recommends the use of cleaner
burning gasoline and appropriately blended
reformulated gasoline. These types of gas-
oline provide excellent vehicle perfor-
mance, reduce vehicle emissions, and im-
prove air quality.
OXYGENATES IN GASOLINE
Toyota allows the use of oxygenate
blended gasoline where the oxygenate
content is up to 10% ethanol or 15%
MTBE. If you use gasohol in your
Toyota, be sure that it has an octane
rating no lower than 87.
Toyota does not recommend the use of
gasoline containing methanol.
GASOLINE CONTAINING MMT
Some gasoline contain an octane en-
hancing additive called MMT (Methylcy-
clopentadienyl Manganese Tricarbonyl).
Toyota does not recommend the use of
gasoline that contains MMT. If fuel con-
taining MMT is used, your emission con-
trol system may be adversely affected.
The Malfunction Indicator Lamp on the in-
strument cluster may come on. If this hap-
pens, contact your Toyota dealer for ser-
vice.

Aluminum wheels: Use only a mild soap
or neutral detergent.
Plastic bumpers: Wash carefully. Do not
scrub with abrasive cleaners. The bumper
faces are soft.
Exterior lights: Wash carefully. Do not use
organic substances or scrub them with a
hard brush. This may damage the sur-
faces of the lights.
Road tar: Remove with turpentine or
cleaners that are marked safe for painted
surfaces.3. Rinse thoroughly—dried soap can cause streaking. In hot weather you
may need to rinse each section right
after you wash it.
4. To prevent water spots, dry the vehicle using a clean soft cotton towel. Do not
rub or press hard—you might scratch
the paint.NOTICE
Do not use organic substances
(gasoline, kerosene, benzine or
strong solvents), which may be tox-
ic or cause damage.
 Do not scrub any part of the ve-
hicle with a hard brush, which may
cause damage.
Automatic car wash
Your vehicle may be washed in an auto-
matic car wash, but remember that the
paint can be scratched by some types of
brushes, unfiltered washing water, or the
washing process itself. Scratching reduces
paint durability and gloss, especially on
darker colors. The manager of the car
wash should be able to advise you wheth-
er the process is safe for the paint on
your vehicle.
NOTICE
With mast type antenna:
To prevent damage to the antenna,
make sure it is removed before
driving your Toyota through an au-
tomatic car wash.
 When your vehicle goes through an
automatic car wash, make sure the
power sliding door and power back
door system are off.
Waxing your Toyota
Polishing and waxing is recommended
to maintain the original beauty of your
Toyota’s finish.
Apply wax once a month or if the vehicle
surface does not repel water well.
1. Always wash and dry the vehicle be- fore you begin waxing, even if you are
using a combined cleaner and wax.
2. Use a good quality polish and wax. If the finish has become extremely weath-
ered, use a car −cleaning polish, fol-
lowed by a separate wax. Carefully fol-
low the manufacturer ’s instructions and
precautions. Be sure to polish and wax
the chrome trim as well as the paint.

Windshield washer nozzles: Make sure
that the nozzles do not become blocked
when waxing. If a nozzle becomes
blocked, contact your Toyota dealer to
have the vehicle serviced.
NOTICE
If a nozzle becomes blocked, do not
try to clear it with a pin or other
object. The nozzle will be damaged.
Exterior lights: Do not apply wax on the
surfaces of the lights. Wax may cause
damage to the lenses. If you accidentally
put wax on the light surfaces, wipe or
wash it off.3. Wax the vehicle again when water does not bead but remains on the sur-
face in large patches.
CAUTION
Vehicles with side airbags and cur-
tain shield airbags:
Be careful not to splash water or
spill liquid on the floor. This may
prevent the side airbag and curtain
shield airbag from activating cor-
rectly, resulting in serious injury.
Do not wash the vehicle floor with
water, or allow water to get onto
the floor when cleaning the vehicle
interior or exterior. Water may get
into audio components or other
electrical components above or un-
der the floor carpet (or mat) and
cause a malfunction; and it may
cause body corrosion.
Vinyl interior
The vinyl upholstery may be easily
cleaned with a mild soap or detergent
and water.
First vacuum over the upholstery to re-
move loose dirt. Then, using a sponge or
soft cloth, apply the soap solution to the
vinyl. After allowing it to soak in for a few
minutes to loosen the dirt, remove the dirt
and wipe off the soap with a clean damp
cloth. If all the dirt do not come off, re-
peat the procedure. Commercial foaming −
type vinyl cleaners are also available
which work well. Follow the manufacturer ’s
instructions.
NOTICE
Do not use solvent, thinner, gasoline
or window cleaner on the interior.

Carpets
Use a good foamtype shampoo to
clean the carpets.
Begin by vacuuming thoroughly to remove
as much dirt as possible. Several types of
foam cleaners are available; some are in
aerosol can sand others are powders or
liquids which you mix with water to pro-
duce a foam. To shampoo the carpets,
use a sponge or brush to apply the foam.
Rub in overlapping circles.
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.

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.
NOTICE
When cleaning the inside of the
rear window, be careful not to
scratch or damage the heater wires
or connectors.
 With onglass antenna: When clean-
ing the inside of the rear window,
be careful not to scratch or damage
the printed antenna.
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.

The following illustrations show how to
gain access to the bulbs. When replacing
a bulb, make sure the ignition switch and
light switch are off. Use bulbs with the
wattage ratings given in the table.
The high mounted stoplight consists of a
number of LEDs. If any of the LEDs burn
out, take your vehicle to your Toyota deal-
er to have the light replaced.
CAUTION
To prevent burning yourself, do not
replace the light bulbs while they
are hot.
Halogen bulbs have pressurized gas
inside and require special handling.
They can burst or shatter if
scratched or dropped. Hold a bulb
only by its plastic or metal case.
Do not touch the glass part of a
bulb with bare hands.
When replacing the rear light bulbs,
turn off the power back door sys-
tem to prevent an unexpected seri-
ous injury.
Vehicles with discharge headlights—
Do not touch the highintensity dis-
charge headlight’s high voltage
socket when the headlights are
turned on. An extremely high volt-
age of 20000 V will be discharged
and could result in serious injury or
death by electric shock.
Do not attempt to take apart or re-
pair the low beam headlight bulbs,
connectors, power supply circuits,
or related components. Doing so
could result in electric shock and
serious injury or death. Call your
Toyota dealer for headlight repair or
servicing, including replacement of
bulbs and bulb disposal.
NOTICE
Only use a bulb of the listed type.
The inside of the lens of exterior lights
such as headlights may temporarily fog up
when the lens becomes wet in the rain or
in a car wash. This is not a problem
because the fogging is caused by the
temperature difference between the outside
and inside of the lens, just like the
windshield fogs up in the rain. However, if
there is a large drop of water on the
inside of the lens, or if there is water
pooled inside the light, contact your
Toyota dealer.
