2003 TOYOTA PRIUS gas type

150
Drive gently and avoid high speeds.
Your vehicle does not need an elaborate
breakin. But following a few simple tips
for the first 1000 km (600 miles) can add
to the future economy and long life of
your vehicle:
Avoid fullthrottle acceleration when
starting and driving.
Avoid racing the hybrid engine.
Try to avoid hard stops during the first
300 km (200 miles).FUEL TYPE
Your vehicle must use only unleaded
gasoline.
To help prevent gas station mixups, your To-
yota has a smaller fuel tank opening.
The
special nozzle on pumps with unleaded fuel
will fit it, but the larger standard 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 3.5M93
in Canada.
NOTICE
Do not use leaded gasoline. Use of
leaded gasoline will cause the three
way catalytic converter to lose its
effectiveness and the emission con-
trol system to function improperly.
Also, this can increase maintenance
costs.
OCTANE RATING
Select unleaded gasoline with an Oc-
tane Rating of 87 (Research Octane
Number 91) or higher. Use of unleaded fuel with an octane num-
ber or rating lower than stated above will
cause persistent heavy knocking. If se-
vere, 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 build
up of engine deposits.
However, all gasoline sold in the U.S. con-
tains detergent additives
to keep clean and/or
clean intake systems.

QUALITY GASOLINE
Automotive manufacturers in the U.S., Eu-
rope and Japan have developed a specifica-
tion for quality fuel named WorldWide
Fuel Charter (WWFC) that is expected to
be applied world wide. The WWFC consists
of three categories that depend on required
emission levels. In the U.S., category 3 has
been adopted. The WWFC improves air
quality by providing for better emissions in
vehicle fleets, and customer satisfaction
through better vehicle performance.
CLEANER BURNING GASOLINE
Cleaner burning gasoline, including refor-
mulated gasoline that contains oxygenates
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. GASOLINE QUALITY
In a very few cases, you may experience
driveability problems caused by the partic-
ular gasoline that you are using. If you
continue to have unacceptable driveability,
try changing gasoline brands. If this does
not rectify your problem, then consult your
Toyota dealer.
NOTICE

Do not use gasohol other than
stated above. It will cause fuel sys-
tem damage or vehicle performance
problems.
 If drivability problems are encoun-
tered (poor hot starting, vaporizing,
engine knock, etc.), discontinue its
use.
 Take care not to spill gasohol dur-
ing refueling. Gasohol may cause
paint damage.

When driving in a coastal area
When driving on a road sprinkled with
antifreeze
When having coal tar, tree sap, bird
droppings and carcass of an insect
When driving in the areas where there
are a lot of smoke, soot, dust, iron
dust and chemical substance
When the vehicle becomes remarkably
dirty with dust and mud
Handwashing your Toyota
Work in the shade and wait until the
vehicle body is not hot to the touch.
CAUTION
When cleaning under floor or chassis,
be careful not to injure your hands.
1. Rinse off loose dirt with a hose. Re- move any mud or road salt from the
underside of the vehicle or in the
wheel wells. 2. Wash with a mild carwash soap,
mixed according to the manufacturer ’s
instructions. Use a soft cotton mitt and
keep it wet by dipping it frequently into
the wash water. Do not rub hard—let
the soap and water remove the dirt.
Plastic wheel ornaments: The plastic
wheel ornaments are damaged easily by
organic substances. If any organic sub-
stances splashes an ornament, be sure to
wash it off with water and check if the
ornament is damaged.
CAUTION
Do not attach the heavily damaged
plastic wheel ornament. It may fly off
the wheel and cause accidents while
the vehicle is moving.
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.
Road tar: Remove with turpentine or
cleaners that are marked safe for painted
surfaces.
NOTICE
Do not use organic substances (gaso-
line kerosene, benzine or strong sol-
vents) which may be toxic or cause
damage.
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.
Automatic car wash
Your vehicle may be washed in an auto-
matic car wash, but remember that the
paint can be scratched by some type 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.

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 does not come off,
repeat the procedure. Commercial foam-
ingtype 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 cans and 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.
NOTICE

Do not use dye or bleach on the
beltsit 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 win-
dows, be careful not to scratch or
damage the heater wires on the rear
window.
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 dirt.

NOTICE
Be sure the hybrid system and all
accessories are off before perform-
ing maintenance.
 When checking the battery, remove
the ground cable from the negative
terminal (“—” mark) first and rein-
stall it last.
 Be careful not to cause a short cir-
cuit with tools.
 Take care no solution gets into the
battery when washing it.
During recharging, the battery is pro-
ducing hydrogen gas.
Therefore, before recharging:
1. If recharging with the battery installed on the vehicle, be sure to disconnect
the ground cable.
2. Make sure the power switch on the recharger is off when connecting the
charger cables to the battery and when
disconnecting them.
CAUTION
Always charge the battery in an un-
confined area. Do not charge the
battery in a garage or closed room
where there is not sufficient ventila-
tion.
Only do a slow charge (3.5A or
less). Charging at a quicker rate is
dangerous. The battery may ex-
plode, causing personal injuries.
NOTICE
Never recharge the battery with the
hybrid system on. Also, be sure all
accessories are turned off.

If any washer does not work, the wash-
er tank may be empty. Check the wash-
er fluid level on the level gauge. If the
washer fluid level is below “LOW”, add
washer fluid.
“
FULL” on the side of the washer tank
indicates the full level of washer fluid. Do
not refill washer fluid over this level.
You may use plain water as washer fluid.
However, in cold areas where tempera-
tures range below freezing point, use
washer fluid containing antifreeze. This
product is available at your Toyota dealer
and most auto parts stores. Follow the
manufacturer ’s directions for how much to
mix with water.
NOTICE
Do not use engine antifreeze or any
other substitute because it may dam-
age your vehicle’s paint.
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
