CHILD RESTRAINT SYSTEM INSTALLA-
TION1. Widen the gap between the seat cushion and seatback slightly and
confirm the position of the lower an-
chorages below the symbol in the
seatback.
2. Type A—Latch the hooks of lower straps onto the anchorages and
tighten the lower straps.
Type B—Latch the buckles onto the
anchorages.
For owners in Canada
The symbol on a child restraint system
indicates the presence of a lower connec-
tor system.
If your child restraint system has a top
strap, it should be anchored. (For the
installation of the top strap, see “—Using
a top strap” on page 98.) For installation details, refer to the instruc-
tion manual equipped with each product.
CAUTION
When using the lower anchorages
for the child restraint system, be
sure that there are no irregular ob-
jects around the anchorages or that
the seat belt is not caught.
Push and pull the child restraint
system in different directions to be
sure it is secure. Follow all the
installation instructions provided by
its manufacturer.
Do not install a child restraint sys-
tem on the rear seat if it interferes
with the lock mechanism of the
front seats. Otherwise, the child or
front seat occupant(s) may be killed
or seriously injured in case of sud-
den braking or a collision.

(d) Using engine braking
To use engine braking, shift the shift lever
to “B” position.
During high speed driving, you may feel
that deceleration by engine braking is less
than that of a typical vehicle.
Do not continue normal driving with the
transaxle in “B” for a long time. This may
cause decreased fuel economy. To prevent
this, use “D” for normal driving.
When you shift the transaxle to “B” from
a position other than “D”, an alarm sounds
and the transaxle is automatically shifted
to “N”.
CAUTION
Be careful when downshifting on a
slippery surface. Abrupt shifting
could cause the vehicle to skid or
spin.
(e) Backing up1. Bring the vehicle to a complete stop.
2. With the brake pedal held down with your foot, shift the shift lever to the
“R” position. You will hear beeps while
the transaxle is in “R”.
When you shift the transaxle to “R” while
driving, an alarm sounds and the transaxle
is shifted to “N”.
(f) Parking 1. Bring the vehicle to a complete stop.
2. With the brake pedal pressed down, fully depress the parking brake pedal
to apply the parking brake securely.
3. With the brake pedal pressed down, push the “P” position switch.
If you press the “POWER” switch while
stopping, the transaxle is automatically
shifted to the “P” and the hybrid system
is turned off. If the driver ’s door is opened when the
transaxle is in “N”, “D” or “B”, beep
sounds and a warning message appears
on the multi
−information display to warn
you to shift the transaxle to “P”.
If you push the “P” position switch while
driving, an alarm sounds and the transaxle
is automatically shifted to “N”.NOTICE
Be sure to put the hybrid transaxle in
“P” when parking. In “N”, the hybrid
battery will not be charged even if the
gasoline engine is running. You can-
not start your vehicle if the transaxle
is left in “N” for a long time because
the hybrid battery will discharge.
When shifting the transaxle from “P” on
the slope, a large parking lock releasing
noise will be generated. However, this
does not indicate a malfunction.

(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 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 12 volt battery is discon- nected
Before you disconnect the 12 volt battery,
confirm the shift position is “P” and apply
the parking brake completely.
After you reconnect the 12 volt battery,
shift the shift lever to “N” and confirm the
shift position is in “N” when the “IG −ON”
mode is enabled.

NOTICE:
This equipment has been tested and
found to comply with the limits for a
Class B digital device, pursuant to Part
15 of the FCC Rules. These limits are
designed to provide reasonable protec-
tion against harmful interference in a

ence to radio or television reception,
which can be determined by turning the
equipment off and on, the user is en-
couraged to try to correct the interfer-
ence by one or more of the following
measures:
Reorient or relocate the receiving an-
tenna.
Increase the separation between the
equipment and receiver.
Connect the equipment into an outlet
on a circuit different from that to
which the receiver is connected.
Consult the dealer or an experienced
radio/TV technician for help.
FCC WARNING:
Changes or modifications not ex-
pressly approved by the party respon-
sible for compliance could void the

ment.
For vehicles sold in Canada
Operation is subject to the following two
conditions:
(1) this device may not cause interfer-
ence, and (2) this device must accept
any interference, including interference
that may cause undesired operation of
the device.
REPLACING TIRES AND WHEELS
When replacing the tires and wheels, be
sure to install tire pressure warning valves
and transmitters. ID codes on the tire
pressure warning valves and transmitters
are registered on the tire pressure warning
ECU. When replacing a tire pressure
warning valve and transmitter, it is neces-
sary to register the ID code of tire pres-
sure warning valve and transmitter. Have
the ID code registered by your Toyota
dealer.
NOTICE
When the tires or tire pressure warn-
ing valves and transmitters must be
replaced, have them replaced by your
Toyota dealer. The tire pressure warn-
ing valves and transmitters will be
affected by the installation or removal
of tires.
