1. To open the fuel filler door, pull thelever up.
When refueling, turn off the hybrid
system.
CAUTION
Do not smoke, cause spark or allow
open flames when refueling. The
fumes are flammable.
When opening the cap, do not re-
move the cap quickly. In hot weath-
er, fuel under pressure could cause
injury by spraying out the filler
neck if the cap is suddenly re-
moved.
Insert the fuel nozzle fully, or fuel
may splash out.

2. To remove the fuel tank cap, turnthe cap counterclockwise by 90 de-
grees (to the pressure point 1), and
then turn it a additional 30 degrees
(to point 2). Pause slightly before
removing it.
It is not unusual to hear a slight swoosh
when the cap is opened.
21p115
3. The removed cap can be stored on the back side of the fuel filler door.
Position the cap so that the hooks point
to the left and right, and set it in the
receptacle on the back side of the door.
When installing the cap, turn the cap
clockwise until you hear a click. When
you hear the click, the cap is fully
closed.
If the cap is not tightened securely, the
malfunction indicator lamp comes on.
Make sure the cap is tightened securely.
The indicator lamp goes off after driving
several times. If the indicator lamp does
not go off, contact your Toyota dealer as
soon as possible.
CAUTION
Make sure the cap is installed se-
curely to prevent fuel sp illage in
the event of an accident.
Use only a genuine Toyota fuel tank
cap for replacement. It is designed
to regulate fuel tank pressure.
NOTICE
To prevent damage to the cap, apply
force only in the turning direction to
the cap. Do not pull or pry it.

Any of the following conditions may oc-
cur, but do not indicate the malfunc-
tion:
The yellow warning light may stay on
for about 60 seconds after “IG−ON”
mode is enabled. It is normal if it turns
off after a while.
Depressing the brake pedal repeatedly
may turn on the red warning light and
buzzer. It is normal if the light turns off
and the buzzer stops sounding after a
few seconds.
You may hear a small sound in the
engine compartment after the hybrid
system is started or the brake p edal is
depressed repeatedly. This is a pump
pulsating sound of the brake system,
and it is not a malfunction.
You may hear a motor sound in the
engine compartment when the brake
pedal is depressed with the hybrid sys-
tem off.
The brake pedal stroke may be short
when you press the “POWER” switch
with the brake pedal depressed. (b) Driver’s Seat Belt Reminder Light
and Buzzer
This light and buzzer remind you to
buckle up the driver’s seat belt.
Once the “IG −ON” mode is enabled, the
reminder light flashes and the buzzer
sounds if the driver ’s seat belt is not fas-
tened. Unless the driver fastens the belt,
the light keeps on flashing and the buzzer
sounds 4 to 8 seconds.
(c) Front Passenger ’s Seat Belt Reminder Light
This light reminds you to buckle up the
front passenger ’s seat belt.
Once the “IG −ON” mode is enabled, the
reminder light flashes if a passenger sits
in the front passenger seat and does not
fasten the seat belt. Unless the front pas-
senger fastens the belt, the light stays
flashing.
If luggage or other load is placed on the
front passenger seat, depending on its
weight and how it is placed on the seat,
built −in sensors in the seat cushion may
detect the pressure, causing the reminder
light to come on. (d) Malfunction Indicator Lamp
This lamp comes on when the “IGON”
mode is enabled and goes off after the
hybrid system 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
following:
Empty fuel tank
If the fuel tank is empty, refuel immedi-
ately.
This case is a temporary malfunction. The
malfunction indicator lamp will go off after
taking several driving trips.
If the lamp does not go off even after
several trips, contact your Toyota deal-
er as soon as possible.
There is a problem somewhere in the
hybrid system or warning light system
itself.
Contact your Toyota dealer as soon as
possible to service the vehicle.

Toyota does not recommend towing a
trailer with your Toyota. It is not de-
signed for trailer towing.Improving fuel economy is easy
−just take
it easy. It will help make your vehicle last
longer, too. Here are some specific tips
on how to save money on both fuel and
repairs:
Keep your tires inflated at the cor-
rect pressure. Underinflation causes
tire wear and wastes fuel. See page
289 for instructions.
Do not carry unneeded weight in
your vehicle. Excess weight puts a
heavier load on the engine, causing
greater fuel consumption.
Accelerate slowly and smoothly.
Avoid jackrabbit starts.
Avoid continuous speeding up and
slowing down. Stop−and− go driving
wastes power.
Avoid unnecessary stopping and
braking. Maintain a steady pace. Try
to time the traffic signals so you only
need to stop as little as possible or
take advantage of through streets to
avoid traffic lights. Keep a proper dis-
tance from other vehicles to avoid sud-
den braking. This will also reduce wear
on your brakes.
Avoid heavy traffic or traffic jams
whenever possible.
Do not rest your foot on brake ped-
al. This causes premature wear, over-
heating and poor fuel economy.
Maintain a moderate speed on high-
ways. The faster you drive, the greater
the fuel consumption. By reducing your
speed, you will cut down on fuel con-
sumption.
Keep the front wheels in proper
alignment. Avoid hitting the curb and
slow down on rough roads. Improper
alignment not only causes faster tire
wear but also puts an extra load on
the engine, which, in turn, wastes fuel.
Keep the bottom of your vehicle free
from mud, etc. This not only lessens
weight but also helps prevent corro-
sion.
Keep your vehicle tunedup and in
top shape . A dirty air cleaner, improp-
er valve clearance, dirty plugs, dirty oil
and grease, brakes not adjusted, etc.
all lower engine performance and con-
tribute to poor fuel economy. For longer
life of all parts and lower operating
costs, keep all maintenance work on
schedule, and if you often drive under
severe conditions, see that your ve-
hicle receives more frequent mainte-
nance.

INSIDE THE VEHICLE
Items listed below should be checked
regularly, e.g. while performing periodic
services, cleaning the vehicle, etc.
Lights
Make sure the headlights, stop lights, tail
lights, turn signal lights, and other lights
are all working. Check headlight aim.
Service reminder indicators and warning
buzzers
Check that all service reminder indicators
and warning buzzers function properly.
Steering wheel
Be alert for changes in steering condition,
such as hard steering or strange noise.
Seats
Check that all front seat controls such as
seat adjusters, seatback recliner, etc. op-
erate smoothly and that all latches lock
securely in any position. Check that the
head restraint move up and down smooth-
ly and that the locks hold securely in any
latched position.Seat belts
Check that the seat belt system such as
buckles, retractors and anchors operate
properly and smoothly. Make sure the belt
webbing is not cut, frayed, worn or dam-
aged.
Accelerator pedal
Check the pedal for smooth operation and
uneven pedal effort or catching.
Brake pedal
Check the pedal for smooth operation and
that the pedal has the proper clearance.
Check the brake booster function.
Brakes
In a safe place, check that the brakes do
not pull to one side when applied.
Parking brake
Check that the pedal has the proper travel
and that, on a safe incline, your vehicle
is held securely with only the parking
brake applied.
OUTSIDE THE VEHICLE
Items listed below should be performed
from time to time, unless otherwise
specified.
Fluid leaks
Check underneath for leaking fuel, oil, wa-
ter or other fluid after the vehicle has
been parked for a while. If you smell fuel
fumes or notice any leak, have the cause
found and corrected immediately.
Doors and engine hood
Check that all doors and trunk operate
smoothly and all latches lock securely.
Make sure the engine hood secondary
latch secures the hood from opening when
the primary latch is released.
Tire inflation pressure
Check the pressure with a gauge ev-
ery two weeks, or at least once a
month. See page 289 for additional
information.

290
Always use a tire inflation pres-
sure gauge. The appearance of
a tire can be misleading. Besides,
tire inflation pressures that are
even just a few pounds off can de-
grade ride and handling.
 Take special care when adding
air to the compact spare tire.
The smaller tire size can gain
pressure very qu ickly. Add com-
pressed air in small quantities and
check the pressure often until it
reaches the specified pressure.
 Do not bleed or reduce tire
inflation pressure after driving.
It is normal for the tire inflation
pressure to be higher after driving.
 Never exceed the vehicle capac-
ity weight. Passenger and lug-
gage weight should be located so
that the vehicle is balanced.
Ti r e inf lat ion
pressure gauge
INSPECTION AND ADJUSTMENT
PROCEDURE 1. Remove the tire valve cap.
2. Press the tip of the tire inflation pressure gauge to the tire valve.
3. Read the pressure using the grad- uations of the gauge.
4. In case the tire inflation pressure
is not within the prescribed range,
insert the compressed air from the
valve. In case of applying too much
air, press the center of the valve
and release the air to adjust. 5. After completing the tire inflation
pressure measurement and adjust-
ment, apply soapy water to the
valve and check for leakage.
6. Install the tire valve cap.
If a gauge and air pump are not avail-
able, have your vehicle checked by
your Toyota dealer.
CAUTION
Be sure to reinstall the tire valve
caps. Without the valve caps, dirt
or moisture could get into the
valve core and cause air leakage.
If the caps have been lost, have
new ones put on as soon as pos-
sible.
Incorrect tire inflation pressure
may waste fuel, reduce the comfort
of driving, reduce tire life and
make your vehicle less safe to
drive.
If a tire frequently needs refilling,
have it checked by your Toyota deal-
er.

Spark ignition system ofyour Toyota
The spark ignition system in your
Toyota meets all requirements of
the Canadian Interference −Causing
Equipment Standard.
Installation of a mobile twoway radio system
As the installation of a mobile
two −way radio system in your ve-
hicle could affect electronic sys-
tems such as multiport fuel injec-
tion system / sequential multiport
fuel injection system, cruise con-
trol system, anti −lock brake sys-
tem, vehicle stability control sys-
tem, SRS airbag system, seat belt
pretensioner system and Toyota
hybrid system, be sure to check
with your Toyota dealer for pre-
cautionary measures or special
instructions regarding installation.
Tires and loading on your Toyota
Underinflated or overinflated
tire inflation pr essure and the
excess load may result in the
deterioration of steering ability
and braking ability, leading to
an accident. Check the tire
inflation pressure periodically
and be sure to keep the load
limits given in this Owner ’s
Manual. For details about tire
inflation pressure and load lim-
its, see page 289 and pages
