Leak detection pump
This pump performs fuel evaporation leakage check. This
check is done approximately five hours after the hybrid
system is turned off. So you may hear s ound coming from
underneath the luggage compartment for several minutes.
It does not indicate a malfunction.
Traction battery
The traction battery has a limited service life. Call your
Toyota dealer or a qualified service shop for information
about re cycling or disposal of the battery.
Scrapping of your Toyota
CAUTION
In the event that your vehicle must be disposed of,
make sure to contact your Toyota dealer or a quali-
fied service shop. If your vehicle is disposed of
without the traction battery having been removed,
there is a danger of serious electric shock if high
voltage parts, cables and their connectors are tou-
ched. The traction batteries must be disposed of by
your Toyota dealer or a qualified service shop. If the
traction batteries are not disposed of properly, they
may cause electric shock that can result a death or
serious injury.
The SRS airbag and seat belt pretensioner devices in your
Toyota contain explosive chemicals. If the vehicle is
scrapped with the airbags and pretensioners left as they
are, this may cause an accident such as fire. Be sure to
have the systems of the SRS airbag and seat belt preten-
sioner removed and disposed of by the qualified service
shop or by your Toyota dealer before you dispose of your
vehicle.

CAUTION
Pull your vehicle off the road, put
the transmission in the “P” posi-
tion, apply the parking brake, turn
the hybrid system off and remove
the key.
In order to avoid personal injuries,
do not touch high voltage wiring,
connectors or high voltage parts
(inverter unit, traction battery and
etc.).
If exposed electric wires are pro-
truding inside or outside of your
vehicle, an electric shock may oc-
cur. Never touch the electric wires.
If fluid leaks or gets into some
parts of the vehicle, never touch it
because it may be strong alkaline
electrolyte from the traction battery.
If it contacts your skin or eyes,
wash it off immediately with a large
amount of water or if possible, bo-
ric acid solution. Get immediate
medical attention in order to help
avoid serious injury.
If a fire occurs in the hybrid ve-
hicle, leave the vehicle as soon as
possible. Never use a fire extin-
guisher that is not meant for elec-
tric fires. Using a small amount of
water may be also dangerous.
If your vehicle needs to be towed,
do it with the front wheels raised
(front wheel drive models) or all
four wheels raised (all models). If
the wheels with the traction motor
are on the ground when towing, the
motor may continue to generate
electricity. This may cause the elec-
tricity leakage. Depending on the
severity of the damage, electricity
leakage may cause fire. See “If your
vehicle needs to be towed” on page
354 in Section 4.
The emergency shut off system blocks
off the high voltage current and stops
the fuel pump to minimize the risk of
the electric leakage and the fuel leak-
age when a certain level of impact is
detected by the impact sensor. If the
system activates, your vehicle will not
restart. To restart the hybrid system,
contact a Toyota dealer.
CAUTION
Check to see if there are exposed
high voltage parts and cables. Nev-
er touch the parts and cables. See
“—High voltage components” on
page 6 in this Section for the loca-
tions of the high voltage parts and
cables.
Inspect the ground under the ve-
hicle. If you find that liquid has
leaked onto the ground, the fuel
system may have been damaged.
Leave the vehicle as soon as pos-
sible.

Always slow down in gusty cross-
winds. Because of its profile and
higher center of gravity, your ve-
hicle is more sensitive to side
winds than an ordinary passenger
car. Slowing down will allow you to
have better control.
When offroad driving cannot be
avoided, do not drive at excessive
speeds, jump, make sharp turns, or
strike objects, etc. These maneu-
vers may result in loss of control
or vehicle rollover causing death or
serious injury. You also risk expen-
sive damage to your vehicle’s sus-
pension and chassis.
Do not drive horizontally across
steep slopes. Driving straight up or
straight down is preferred. Your ve-
hicle (or any similar offroad ve-
hicle) can tip over sideways much
more easily than forward or back-
ward.
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 hybrid system.
Try to avoid hard stops during the first
300 km (200 miles).
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.

REGENERATIVE BRAKE
When the brake is applied, the motor gen-
erator converts kinetic energy into electric
energy.
The regenerative brake works in the fol-
lowing operations.
1. When the accelerator pedal is released, the reduced speed equal to engine
braking in a gasoline −fueled vehicle is
obtained in accordance with the running
mode position of the selector lever.
2. When the brake pedal is depressed with the selector lever in “D” or “B”,
the regenerative brake works.
HYDRAULIC BRAKE
This brake system has 3 independent hy-
draulic circuits. If any 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 the buzzer sounds continu-
ously. 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, im-
mediately stop your vehicle and contact
your Toyota dealer.
The red and yellow brake system warning
lights may stay on for about 60 seconds
after the ignition is turned on. It is normal
if the light turns off after a while.
Depressing the brake pedal repeatedly
may turn on the red warning light. It is
normal if the light turns off after a few
seconds.
You may hear a 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 sys-
tem is off and about 90 seconds have
passed.
The brake pedal stroke may be short
when you turn the ignition on with the
brake pedal depressed.
CAUTION
Do not pump the brake pedal if the
hybrid system is not operating.
Each push on the pedal uses up
your reserved brake fluid pressure.
Even if the power assist is com-
pletely lost, the brakes will still
work. But you will have to push the
pedal hard, much harder than nor-
mal. And your braking distance will
increase.

Tire pressure gauge
INSPECTION AND ADJUSTMENT
PROCEDURE 1. Remove the tire valve cap.
2. Press the tip of the tire 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 ad-
justment, 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 infl ation pressure may
waste fuel, reduce the comfort of driv-
ing, reduce tire life and make your ve-
hicle less safe to drive.
If a tire frequently needs refilling,
have it checked by your Toyota deal-
er.
CAUTION
Keep your tires properly inflated.
Otherwise, the following condi-
tions may occur and cause an ac-
cident resulting in death or seri-
ous injuries.
Low tire pressure ( underinfla-
tion)—
 Excessive wear
 Uneven wear
 Poor handling
 Possibility of blowouts from an
overheated tire
 Poor sealing of the tire bead
 Wheel deformation and/or tire
separation
 A greater possibility of tire
damage from road hazards
