Road accident cautions
Observe the following precautions to reduce the risk of death or serious injury:
Stop the vehicle in a safe place to prevent subsequent accidents. While
depressing the brake pedal, apply the parking brake and shift the shift position
to P to stop the hybrid system. Then, slowly release the brake pedal.
Do not touch the high voltage parts, cables and connectors.
If electric wires are exposed inside or outside your vehicle, an electric shock
may occur. Never touch exposed electric wires.
If a fluid leak occurs, do not touch the fluid as it may be strong alkaline elec-
trolyte from the hybrid battery (traction battery). If it comes into contact with
your skin or eyes, wash it off immediately with a large amount of water or, if
possible, boric acid solution. Seek immediate medical attention.
If a fire occurs in the hybrid vehicle, leave the vehicle as soon as possible.
Never use a fire extinguisher that is not meant for electric fires. Using even a
small amount of water may be dangerous.
If your vehicle needs to be towed, do so with front wheels raised. If the
wheels connected to the electric motor (traction motor) are on the ground
when towing, the motor may continue to generate electricity. This may cause
an electricity leakage leading to a fire. (
P. 562)
Carefully inspect the ground under the vehicle. If you find that liquid has
leaked onto the ground, the fuel system may have been damaged. Leave the
vehicle as soon as possible.

Immobilizer system
The indicator light flashes after the
power switch has been turned off to
indicate that the system is operat-
ing.
The indicator light stops flashing
after the power switch has been
turned to ACCESSORY or ON
mode to indicate that the system has
been canceled.
System maintenance
The vehicle has a maintenance-free type immobilizer system.
Conditions that may cause the system to malfunction
If the grip portion of the key is in contact with a metallic object
If the key is in close proximity to or touching a key registered to the security
system (key with a built-in transponder chip) of another vehicle
The vehicle’s keys have built-in transponder chips that prevent the hybrid
system from starting if a key has not been previously registered in the
vehicle’s on-board computer.
Never leave the keys inside the vehicle when you leave the vehicle.
This system is designed to help prevent vehicle theft but does not guar-
antee absolute security against all vehicle thefts.

A locked door is unlocked or opened in any way other than using the
entry function (if equipped) or wireless remote control.
The hood is opened.
The intrusion sensor detects something moving inside the vehicle. (An
intruder gets in the vehicle.)
The tilt sensor detects a change of vehicle inclination. (if equipped)
The back door window is broken. (if equipped)
Close the doors and hood, and lock
all the doors using the entry func-
tion (if equipped) or wireless
remote control. The system will be

vehicle is towed away.
This system is designed to deter and prevent vehicle theft but does not
guarantee absolute security against all intrusions.
Setting the intrusion sensor and tilt sensor
The intrusion sensor and tilt sensor will be set automatically when the
alarm is set. (P. 9 3 )
Canceling the intrusion sensor and tilt sensor
If you are leaving pets or other moving things inside the vehicle, make
sure to disable the intrusion sensor and tilt sensor before setting the
alarm, as they will respond to movement inside the vehicle.
Turn the power switch off.
Press the intrusion sensor and
tilt sensor cancel switch.
A message will be shown on
the multi-information display
in the instrument cluster.
The intrusion sensor and tilt
sensor will revert to on each
time the power switch is

Intrusion sensor detection considerations
The sensor may trigger the alarm in the following situations:
Places with extreme vibrations or noises, or situations in which the vehicle is
subject to repeated impacts or vibrations:
• When parked in a parking garage
• When the vehicle is transported by a ferry, trailer, train, etc.
• When ice adhering to the vehicle is removed
• When the vehicle is in an automatic or high-pressure car wash
• When in a hail or lightning storm
Tilt sensor detection considerations
The sensor may trigger the alarm in the following situations:
The vehicle is transported by a ferry, trailer, train, etc.
The vehicle is parked in a parking garage.
The vehicle is inside a car wash that moves the vehicle.
Any of the tires loses air pressure.
The vehicle is jacked up.
An earthquake occurs or the road caves in.
A window or the moon roof (if equipped)
is open.
In this case, the sensor may detect the fol-
lowing:
• Wind or the movement of objects such
as leaves and insects inside the vehicle
• Ultrasonic waves emitted from devices
such as the intrusion sensors of other
vehicles
• The movement of people outside the
vehicle
Unstable items, such as dangling accesso-
ries or clothes hanging on the coat hooks,
are in the vehicle.
