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.

Look at the seethrough coolant reser-
voir when the hybrid system is cold.
The coolant level is satisfactory if it is
between the “FULL” and “LOW” lines
on the reservoir. If the level is low, add
coolant. (For coolant types, see “Cool-
ant type selection” described below.)
The coolant level in the reservoir will vary
with hybrid system temperature. However,
if the level is on or below the “LOW” line,
add coolant. Bring the level up to the
“FULL” line.
If the coolant level drops within a short
time after replenishing, there may be a
leak in the system. Visually check the
radiator, hoses, radiator cap and drain
cock and water pump.
If you can find no leak, have your Toyota
dealer test the cap pressure and check
for leaks in the cooling system.
CAUTION
To prevent burning yourself, do not
remove the radiator cap when the
coolant may be hot.
Coolant type selection
Use of improper coolants may damage
your cooling system.
Only use “Toyota Super Long Life Coolant”
or similar high quality ethylene glycol
based non−silicate, non −amine, non −nitrite,
and non− borate coolant with long −life
hybrid organic acid technology. (Coolant
with long −life hybrid organic acid
technology is a combination of low
phosphates and organic acids.)
For the U.S.A.—“Toyota Super Long Life
Coolant” is a mixture of 50% coolant and
50% deionized water. This coolant pro-
vides protection down to about −35 C
( − 31 F).
For Canada—“Toyota Super Long Life
Coolant” is a mixture of 55% coolant and
45% deionized water. This coolant pro-
vides protection down to about −42 C
( − 44 F).
NOTICE
Do not use plain water alone.
Toyota recommends “Toyota Super Long
Life Coolant”, which has been tested to
ensure that it will not cause corrosion nor
result in malfunction of your coolant
system with pr oper usage. “Toyota Super
Long Life Coolant” is formulated with
long −life hybrid organic acid technology
and has been specifically designed to
avoid cooling system malfunction on
Toyota vehicles.
Please contact your Toyota dealer for
further details.

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
