(g) Vehicle driving characteristics
Creeping
In order to hold the vehicle properly on an
incline and for better accelerator pedal
operation at starting, your vehicle is de-
signed like a typical automatic transmis-
sion vehicle which tends to move without
depressing the accelerator pedal with the
transaxle in a position other than “P” or
“N”.
With the transaxle in a position other than
“P” or “N”, depress the brake pedal firmly
even when stopped and apply the parking
brake as required.
When moving in a compact area or during
a traffic jam, it is an effective way to
control the speed using only the brake
pedal operation without depressing the ac-
celerator pedal.
Regenerative brake
When the accelerator pedal is released or
the brake pedal is depressed, the electric
motor acts as a generator and converts
kinetic energy to electric energy to provide
deceleration and recover electric energy to
charge the hybrid vehicle battery.
At this time, the electric motor running
noise may increase.The operation is the same as a typical
gasoline powered vehicle.
You may experience the following condi-
tion while braking. As they do not indicate
a malfunction, perform braking as usual:
In the “OFF” mode, pressing the
“POWER” switch once or twice will se-
lect “ACC” or “IG
−ON” only if the brake
pedal is not depressed. In this condi-
tion, the brake pedal may move a little.
Hybrid driving
This vehicle runs in combination with the
gasoline engine and electric motor.
If the “READY” light is on, you can start
your vehicle even with the gasoline engine
stopped. (h) If the system malfunctions
In the following conditions, there is some
problem in the system.
The indicator on the “P” position switch
flashes. However, this does not indi-
cate a malfunction unless a warning
message appears in the multi
−informa-
tion display.
All frames of shift position indicators in
the instrument cluster flash.
The parking system error message ap-
pears on the multi −information display.
The instrument cluster and multi −infor-
mation display does not come on when
the “IG −ON” mode is enabled.
In these cases, stop your vehicle in a
safe and level place, apply the parking
brake securely and contact your Toyota
dealer immediately.
(i) When the auxiliary battery is dis- connected
Before you disconnect the aux iliary bat-
tery, confirm the shift position is “P” and
apply the parking brake completely.
After you reconnect the auxiliary battery,
shift the shift lever to “N” and confirm the
shift position is in “N” when the “IG −ON”
mode is enabled.

Never allow anyone to ride in
the luggage compartment. It is
not designed for passengers.
They should ride in their seats
with their seat belts properly
fastened. Otherwise, they are
much more likely to suffer seri-
ous bodily injury, in the event
of sudden braking or a colli-
sion.
 Do not place anything on the
luggage cover. Such items may
be thrown about and possibly
injure people in the vehicle
during sudden braking or an
accident. Secure all items in a
safe place.
 Do not drive with objects left
on top of the instrument panel.
They may interfere with the
driver’s field of view. Or they
may move during sharp vehicle
acceleration or turning, and im-
pair the driver’s control of the
vehicle. In an accident they
may injure the vehicle occu-
pants.NOTICE
Do not load the vehicle beyond
the vehicle capacity weight giv-
en in Section 9.
Cargo capacity depends on the to-
tal weight of the occupants.
(Cargo capacity) = (Total load capac-
ity) – (Total weight of occupants)
STEPS FOR DETERMINING COR-
RECT LOAD LIMIT
1. Locate the statement “The com- bined weight of occupants and car-
go should never exceed XXX
pounds” on your vehicle’s placard.
2. Determine the combined weight of the driver and passengers that will
be riding in your vehicle.
3. Subtract the combined weight of the driver and passengers from
XXX kilograms or XXX pounds.

CAUTION
Before driving off, make sure the
parking brake is fully released and
the parking brake reminder light is
off.
Do not leave your vehicle unat-
tended with the “READY” light on.
Do not rest your foot on the brake
pedal while driving. It can cause
dangerous overheating, needless
wear, and poor fuel economy.
To drive down a long or steep hill,
reduce your speed and downshift.
Remember, if you ride the brakes
excessively, they may overheat and
not work properly.
Be careful when accelerating or
braking on a slippery surface. Sud-
den acceleration or engine braking,
could cause the vehicle to skid or
spin.
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 for engine coolant.
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.)
See “Checking the coolant level” on page
284 for details of coolant type selection.
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.
