SECTION 3

Drive gently and avoid high speeds.
Your vehicle does not need an elaborate
break−in. 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 full −throttle 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
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 unleaded gasoline with an Oc-
tane Rating of 87 (Research Octane
Number 91) or higher. Use of unleaded fuel with an octane rating
lower than 87 may result in engine knock-
ing. Persistent knocking can lead to en-
gine 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.

Fuel

322
FUEL TANK CAPACITY45 L (11.9 gal., 9.9 lmp.gal.)
The given fuel tank capacity is measured
on EPA/CARB ORVR testing condition
which is approved for nominal capacity
measurement condition.
The fuel tank capacity is decreased at low
ambient temperature. (decreased by about
5 L (1.3 gal., 1.1 lmp.gal.) at −10 \bC
(14 \bF).)
Fuel pump shutoff system
The fuel pump shut −off system stops sup-
plying fuel to the engine to minimize the
risk of fuel leakage when the engine stalls
or an airbag inflates upon collision. To
restart the hybrid system after the fuel
pump shut −off system activates, press the
“POWER” switch to the “OFF” mode and
start it.
CAUTION
Inspect the ground under the vehicle
before restarting the hybrid system. If
you find that fuel has leaked onto the
ground, the fuel system has been
damaged and is in need of repair. In
this case, do not restart the hybrid
system.
If you plan to drive your Toyota in
another country...
First , comply with the vehicle registration
laws.
Second, confirm the availability of the cor-
rect fuel (unleaded and minimum octane
number).

REGENERATIVE BRAKE
When the brake is applied, the electric
motor used as a generator converts kinet-
ic energy into electric energy.
The regenerative brake works in the fol-
lowing operations.1. When the accelerator pedal is re- leased, the reduced speed equal to en-
gine braking in a gasoline −fueled ve-
hicle is obtained in accordance with the
running mode position of the shift le-
ver.
2. When the brake pedal is depressed with the shift lever in “D” or “B”, the
regenerative brake works. HYDRAULIC BRAKE
This brake system has 3 independent hy-
draulic circuits. If either circuit should fail,
the other will still work. However, the ped-
al will be harder to press, and your stop-
ping distance will increase. Also, the
brake system warning light may come on.
CAUTION
Do not drive your vehicle with only a
single brake system. Have your
brakes fixed immediately.
BRAKE ACTUATOR
The brake actuator uses brake fluid pres-
surized by the pump to power
−assist the
brakes. If the brake actuator fails during
driving, the brake system warning light
comes on and buzzer sounds continuous-
ly. In this case, the brakes may not work
properly. If they do not work well, depress
the brake pedal firmly. If the brake system
warning light comes on, immediately stop
your vehicle and contact your Toyota deal-
er. The red and yellow brake system warning
light may stay on for about 60 seconds
after the “IG
−ON” mode is enabled. It is
normal if the light turns off after a while.
Depressing the brake pedal repeatedly
may turn on the red and yellow brake
system warning light and buzzer. It is nor-
mal 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 pedal is depressed
repeatedly. This is a pump pulsating
sound of the brake system, and it is not
a malfunction.
In the following conditions, you may hear
a motor sound in the engine compartment.
The brake pedal is depressed when the
hybrid system is turned off.
The driver ’s door is opened.
For a few seconds after the hybrid
system is “OFF” and a bout 90 seconds
have passed.
The brake pedal stroke may be short
when you press the “POWER” switch with
the brake pedal depressed.

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.

Hybrid battery
The hybrid battery has a limited
service life. Call your Toyota deal-
er for information about recycling
or disposal of hybrid battery and
your vehicle.
Leak detectionpump
This pump performs fuel evapora-
tion leakage check. This check is
done approximately five hours af-
ter the hybrid system is turned
off. So you may hear a sound
coming from underneath the lug-
gage compartment for several min-
utes. It does not indicate a mal-
function.
PerchlorateMaterial
Special handling may apply,
See www.dtsc.ca.gov/hazardou-
swaste/perchlorate.
Your vehicle has components that
may contain perchlorate. These
components may include airbag,
seat belt pretensioners, and wire-
less remote control batteries.
