: If equipped
The system sounds the alarm and flashes lights when forced entry is
detected.
Triggering of the alarm
The alarm is triggered in the following situations when the alarm
is set.
A locked door or back door is unlocked or opened in any way
other than using the entry function or wireless remote control.
The hood is opened.
If equipped, the intrusion sensor detects something moving
inside the vehicle. (An intruder gets in the vehicle.)
If equipped, the quarter windows or back door window are
tapped or broken.
Setting the alarm system
Close the doors and hood,
and lock all doors using the
entry function or wireless
remote control. The system

Intrusion sensor (if equipped)
The intrusion sensor detects intruders or movement in the vehicle.
When an intruder or movement is detected, the alarm will be trig-
gered.
The intrusion sensor can be canceled using the cancel switch.
This system is designed to deter and prevent vehicle theft but does
not guarantee absolute security against all intrusions.
Canceling the intrusion sensor
Turn the “POWER” switch off
and press the intrusion sensor
cancel switch.
Pressing the switch again will re-
enable the intrusion sensor.
The intrusion sensor will revert to
on each time the “POWER”
switch is turned to ON mode.
Deactivating or stopping the alarm
Do one of the following to deactivate or stop the alarm:
Unlock the doors using the entry function or wireless remote
control.
Start the hybrid system. (The alarm will be deactivated or
stopped after a few seconds.)

Alarm-operated door lock
When the alarm is operating, the doors are locked automatically to pre-
vent intruders.
Do not leave the key inside the vehicle when the alarm is operating, and
make sure the key is not inside the vehicle when recharging or replacing
the 12-volt battery.
Canceling and automatic re-enabling of the intrusion sensor
The alarm will still be set even when the intrusion sensor is canceled.
After the intrusion sensor is canceled, pressing the “POWER” switch or
unlocking the doors using the entry function or wireless remote control
will re-enable the intrusion sensor.
When the alarm system is set again, the intrusion sensor will be set.
Intrusion sensor considerations
The sensor may trigger the alarm in the following situations:
Persons or pets are in the vehicle.
A window is open.
In this case, the sensor may detect the
following:
• Wind or the movement of objects
such as leaves and insects inside
the vehicle
• Ultrasonic waves emitted from
devices such as the intrusion sen-
sors of other vehicles
• The movement of people outside
the vehicle

Before driving
PRIUS +_OM_OM47821E_(EE)The main SRS airbag system components are shown above. The
SRS airbag system is controlled by the airbag sensor assembly. As
the airbags deploy, a chemical reaction in the inflators quickly fills the
airbags with non-toxic gas to help restrain the motion of the occu-
pants.
If the SRS airbags deploy (inflate)
Bruising and slight abrasions may result from contact with a deploying
(inflating) SRS airbag.
A loud noise and white powder will be emitted.
Parts of the airbag module (steering wheel hub, airbag cover and inflator)
as well as the front seats, parts of the front and rear pillars, and roof side
rails, may be hot for several minutes. The airbag itself may also be hot.
The windshield may crack.
SRS airbag deployment conditions (SRS front airbags)
The SRS front airbags will deploy in the event of an impact that exceeds
the set threshold level (the level of force corresponding to an approxi-
mately 20 - 30 km/h [12 - 18 mph] frontal collision with a fixed wall that
does not move or deform).
However, this threshold velocity will be considerably higher if the vehicle
strikes an object, such as a parked vehicle and sign pole, which can move
or deform on impact, or if the vehicle is involved in an underride collision
(e.g. a collision in which the front of the vehicle “underrides”, or goes
under, the bed of a truck, etc.).
Depending on the type of collision, it is possible that only the seat belt
pretensioners will activate.

Headlight control sensor (if equipped)
Automatic light off system
When the light switch is in the
, , or position: The
headlights turn off automatically if the “POWER” switch is turned to
ACCESSORY mode or OFF.
When the light switch is in the AUTO position: The headlights and all
lights turn off automatically if the “POWER” switch is turned to ACCES-
SORY mode or OFF and the driver’s door is opened.
To turn the lights on again, turn the “POWER” switch to ON mode, or turn the
light switch off once and then back to the
, , or posi-
tion.
The sensor may not function properly if
an object is placed on the sensor, or any-
thing that blocks the sensor is affixed to
the windshield.
Doing so interferes with the sensor
detecting the level of ambient light and
may cause the automatic headlight sys-
tem to malfunction.
Air conditioning operation may also be
interrupted.

Automatic headlight leveling system (if equipped)
The level of the headlights is automatically adjusted according to the number
of passengers and the loading condition of the vehicle to ensure that the
headlights do not interfere with other road users.
Customization
Settings (e.g. light sensor sensitivity) can be changed.
(Customizable features P. 554)
NOTICE
To prevent 12-volt battery discharge
Do not leave the lights on longer than necessary when the hybrid system is
off.

Windshield wipers and washer
The wiper operation is selected by moving the lever as follows.
When “AUTO” is selected, the wipers will operate automatically
when the sensor detects falling rain. The system automatically
adjusts wiper timing in accordance with rain volume and vehicle
speed.
When “AUTO” is selected, the sensor sensitivity can be adjusted
as follows by turning the switch ring:
Rain-sensing wiper opera-
tion
Low speed wiper operation
High speed wiper operation
Temporary operation
