The hybrid system automatically con-
trols the level of electrical power re-
maining in the hybrid vehicle battery.
With the selector lever in a position
other than “N”, electricity is generated
and charging occurs when the level of
electrical power in the hybrid vehicle
battery decreases. It is unnecessary to
charge the hybrid vehicle battery from
outside.
INFORMATION:
The gasoline engine starts and stops
automatically. (It stops during a low
load driving, deceleration or when the
vehicle stopped.)
If the “READY” light remains on, you
can start your vehicle using the electric
motor even with the gasoline engine
stopped.
The gasoline engine may not stop auto-
matically in the following conditions:
 During under gasoline engine warm
up
 During hybrid vehicle battery charg-
ing
 When the air conditioning is used in
the “MAX” mode, the gasoline engine
is frequently used. If the output control warning light ()
comes on in the instrument cluster, the
hybrid vehicle battery temperature is
low or high, or the hybrid vehicle bat-
tery capacity is decreased with the se-
lector lever at “R” during driving. As it
does not indicate the failure of the sys-
tem, you can continue driving but avoid
hard acceleration because the power is
insufficient (which is caused by the bat-
tery power deterioration).
The vehicle runs in combination with
the gasoline and electric power. Pay
special attention to the following items.
Be careful of a high voltage and high
temperature.
Your vehicle is equipped with the orange
colored cables connected to the hybrid
vehicle battery which contain a high volt-
age (about 300 V) and to other high volt-
age parts.
CAUTION
Do not touch or come in contact with
orange cables or battery terminals.
Electric shock may cause serious in-
jury or death. Read all caution labels.
A electric motor, coolant radiator and
some other parts reach high temperature
when you are driving. Caution labels are
applied to these parts. Carefully observe
the instructions on these caution labels.
10.Precautions for use

168
Do not drive in excess of the speed
limit. Even if the legal speed limit
permits it, do not drive over 140
km/h (85 mph) unless your vehicle
has highspeed capability tires.
Driving over 140 km/h (85 mph)
may result in tire failure, loss of
control and possible injury. Be sure
to consult a tire dealer to determine
whether the tires on your vehicle
are highspeed capability tires or
not before driving at such speeds.
Do not continue normal driving
when the brakes are wet. If they are
wet, your vehicle will require a lon-
ger stopping distance, and it may
pull to one side when the brakes
are applied. Also, the parking brake
will not hold the vehicle securely.
Make sure you have a proper freeze
protection of coolant.
Your coolant must contain ethyleneglycol
type coolant for a proper corrosion
protection of aluminum components. Use
“Toyota Genuine Long Life Coolant” or
equivalent.
See 217 page in Section 82 for details
about coolant type selection.
NOTICE
Do not use alcohol type antifreeze or
plain water alone.
When it is extremely cold, we recommend
to use 60% solution for your Toyota, to
provide protection down to about 50°C
(58 °F). Do not use more than 70% solu-
tion for better coolant performance.
Check the condition of the auxiliary
battery and cables.
Cold temperatures reduce the capacity of
any auxiliary battery, so it must be in top
shape to provide enough power for winter
starting. Section 83 tells you how to
visually inspect the auxiliary battery. Your
Toyota dealer will be pleased to check the
level of charge. Make sure the engine oil viscosity is
suitable for the cold weather.
See 215 page in Section 82 for recom-
mended viscosity. Leaving a heavy sum-
mer oil in your vehicle during winter
months may cause harder starting. If you
are not sure about which oil to use, call
your Toyota dealer—he will be pleased to
help.
Keep the door locks from freezing.
Squirt lock deicer or glycerine into the
locks to keep them from freezing.
Use a washer fluid containing an anti
freeze solution.
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 as washer fluid be-
cause it may damage your vehicle’s
paint.

CAUTION
To prevent burning yourself, do not
remove the radiator cap when the en-
gine is hot.
158.Coolant type selection
Use of improper coolants may damage
your cooling system. Your coolant must
contain ethyleneglycol type coolant for a
proper corrosion protection of your hybrid
system that contains aluminum compo-
nents. We have used “Toyota Genuine
Long Life Coolant” in your Toyota vehicle.
In order to avoid technical problems, we
strongly recommend using “Toyota Genu-
ine Long Life Coolant” or equivalent.
In addition to preventing freezing and sub-
sequent damage to the hybrid system, this
type of coolant will also prevent corrosion.
Further supplemental inhibitors or additives
are neither needed nor recommended.
Read the coolant container for information
on freeze protection. Follow the manufac-
turer’s directions for how much to mix
with plain water (preferably demineralized
water of distilled water). The total capacity
of the cooling system is given on page
242 in Section 9. We recommend to use 50% solution for
your Toyota, to provide protection down to
about 35
°C (31 °F). When it is extremely
cold, to provide protection down to about
50° C (58 °F), 60% solution is recom-
mended. Do not use more than 70% solu-
tion for better coolant performance.NOTICE
Do not use alcohol type antifreeze or
plain water alone.
The engine cooling system is integral to
maximizing performance of your Toyota
vehicle. In line with this, it is strongly
recommended that you use “Toyota Genu-
ine Long Life Coolant” for protecting the
system, as it is an ethyleneglycol based
premium antifreeze coolant with excellent
corrosion protection properties that has
been specifically formulated for use in
Toyota vehicles.
Please contact your Toyota dealer for fur-
ther details of the “Toyota Genuine Long
Life Coolant” range.
