148 1-7. Theft deterrent system
PRIUS +_OM_OM47841E_(EE)
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

CAUTION
Limitations of the pre-crash safety system
Do not overly rely on the pre-crash safety system. Always drive safely, taking
care to observe your surroundings and checking for any obstacles or other
road hazards.
Failure to do so may cause an accident resulting in death or serious injury.
Cautions regarding the assist contents of the system
By means of alarms and brake control, the pre-crash safety system is
intended to assist the driver in avoiding collisions through the process of
LOOK-JUDGE-ACT. There are limits to the degree of assistance the system
can provide, so please keep in mind the following important points.
Assisting the driver in watching the road
The pre-crash safety system is only able to detect obstacles directly in
front of the vehicle, and only within a limited range. It is not a mechanism
that allows careless or inattentive driving, and it is not a system that can
assist the driver in low-visibility conditions. It is still necessary for the driver
to pay close attention to the vehicle’s surroundings.
Assisting the driver in making correct judgement
When attempting to estimate the possibility of a collision, the only data
available to the pre-crash safety system is that from obstacles it has
detected directly in front of the vehicle. Therefore, it is absolutely neces-
sary for the driver to remain vigilant and to determine whether or not there
is a possibility of collision in any given situation.
Assisting the driver in taking action
The pre-crash safety system’s braking assist feature is designed to help
reduce the severity of a collision, and so only acts when the system has
judged that a collision is unavoidable. This system by itself is not capable
of automatically avoiding a collision or bringing the vehicle to a stop safely.
For this reason, when encountering a dangerous situation the driver must
take direct and immediate action in order to ensure the safety of all
involved.

CAUTION
Chemicals in the 12-volt battery
The 12-volt battery contains poisonous and corrosive sulfuric acid and may
produce hydrogen gas which is flammable and explosive. To reduce the risk
of death or serious injury, take the following precautions while working on or
near the 12-volt battery:
Do not cause sparks by touching the 12-volt battery terminals with tools.
Do not smoke or light a match near the 12-volt battery.
Avoid contact with eyes, skin and clothes.
Never inhale or swallow electrolyte.
Wear protective safety glasses when working near the 12-volt battery.
Keep children away from the 12-volt battery.
Where to safely charge the 12-volt battery
Always charge the 12-volt battery in an open area. Do not charge the 12-volt
battery in a garage or closed room where there is insufficient ventilation.
How to recharge the 12-volt battery
Only perform a slow charge
*. The 12-volt battery may explode if charged at
a quicker rate.
*: 4 A or less on vehicles without alarm and a navigation system.
5 A or less on vehicles with alarm or a navigation system.
