The spark ignition system in your
Toyota meets all requirements of
the Canadian Interference −Causing
Equipment Standard.
Installation of a mobile twoway radio system
As the installation of a mobile
two −way radio system in your ve-
hicle could affect electronic sys-
tems such as multiport fuel injec-
tion system / sequential multiport
fuel injection system, cruise con-
trol system, anti −lock brake sys-
tem, SRS airbag system, seat belt
pretensioner system and Toyota
hybrid system, be sure to check
with your Toyota dealer for pre-
cautionary measures or special
instructions regarding installation.
Scrapping of your Toyota
The SRS airbag and seat belt pre-
tensioner 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
pretensioner removed and disposed
of by the qualified service shop or
by your Toyota dealer before you
dispose of your vehicle.

recycling or disposal of hybrid ve-
hicle battery and your vehicle.

Precautions for useof hybrid vehicle
The vehicle has both high voltage
DC and AC systems as well as a
12volt system. DC and AC high
voltage are both very dangerous
and can cause death or serious inju-
ry, severe burns and electric shock.
In order to avoid personal in-
juries, do not touch the high
voltage cables (orange col-
ored) and their connectors.
Follow the caution labels at-
tached to the high voltage
parts.
Do not remove or replace the
high voltage parts such as
the inverter unit (located in
the engine compartment), hy-
brid vehicle battery (located
between rear seat and trunk),
etc.
Do not touch the service plug
located in the left side trim
of the trunk without hybrid
system technical training.
(See “Precautions for use” on
page 12 in Section 12.) This
component is provided to dis-
able the high voltage system
in case of servicing at a To-
yota dealer.

Do not touch the service plug.
The service plug is installed in the left
side trim of the trunk. It is provided to
shut out high voltage current of the hybrid
vehicle battery when the vehicle is in
need of repairs at a Toyota dealer.
CAUTION
The shaded parts in the illustration
are subjected to a high voltage.
Inappropriate handling may cause
an electric shock resulting in seri-
ous injury or death. Never touch
any item in shaded area.
Keep your hybrid vehicle’s driving char-
acteristics in mind.
As the vehicle runs with both the gaso-
line engine and electric motor, you may
hear a motor sound coming from the
engine compartment.
When the ignition switch is turned to
on or off, you may hear a sound com-
ing from the hybrid vehicle battery in
the trunk. However, this does not indi-
cate any trouble.
If the “READY” light is on, you can
start even with the gasoline engine
stopped.
When the hybrid vehicle battery tem-
perature is low or high, or the hybrid
vehicle battery capacity is decreased
with the selector lever at “R” during
driving, the output control warning light
comes on and the output might be lim-
ited for longer battery charge life.
If the output control warning light is on,
drive your vehicle without hard accel-
eration. The output power will be limit-
ed particularly when backing up.

This indicator comes on when the igni-
tion key is turned to the “ACC” or
“ON” position. It goes off after about
6 seconds. This means the front seat
belt pretensioners are operating proper-
ly.
The warning light system monitors the air-
bag sensor assembly, front airbag sen-
sors, side airbag sensors, front seat belt
pretensioner assemblies, warning light, in-
terconnecting wiring and power sources.
(For details, see “Service reminder indica-
tors and warning buzzers” on page 91 in
Section 2−4.)
22p011
The front seat belt pretensioner system
mainly consists of the following compo-
nents and their locations are shown in the
illustration.
1. Front airbag sensors
2. SRS warning light
3. Front seat belt pretensioner assemblies
4. Airbag sensor assembly
The front seat belt pretensioners are con-
trolled by the airbag sensor assembly. The
airbag sensor assembly consists of a saf-
ing sensor and airbag sensor. When the front seat belt pretensioners are
activated, an operating noise may be
heard and a small amount of smoke
−like
gas may be released. This gas is harm-
less and does not indicate that a fire is
occurring.
Once the front seat belt pretensioners
have been activated, the seat belt retrac-
tors remain locked.
CAUTION
Do not modify, remove, strike or open
the front seat belt pretensioner as-
semblies, airbag sensor or surround-
ing area or wiring. Doing any of
these may cause sudden operation of
the front seat belt pretensioners or
disable the system, which could re-
sult in death or serious injury.
Failure to follow these instructions
can result in death or serious inju-
ries.
