WARNING
■SRS airbag precautions
●Do not hang coat hangers or other hard obje cts on the coat hooks. All of these items
could become projectiles and may cause deat h or serious injury, should the SRS cur-
tain shield airbags deploy.
●If a vinyl cover is put on the area where the SRS knee airbag will deploy, be sure to
remove it.
●Do not use seat accessories which cover the parts where the SRS side airbags inflate
as they may interfere with inflation of th e airbags. Such accessories may prevent the
side airbags from activating correctly, disable the system or cause the side airbags to
inflate accidentally, resulting in death or serious injury.
●Do not allow anyone to kneel on the passen-
ger seat toward the door or put their head or
hands outside the vehicle.
●Do not attach anything to or lean anything
against areas such as the dashboard, steering
wheel pad, lower portion of the instrument
panel and door of the glove box.
These items can become projectiles when the
SRS driver, front passenger and knee airbags deploy.
●Do not attach anything to areas such as a door,
windshield glass, side door glass, front or rear
pillar, roof side rail and assist grip. (Except for
the speed limit sticker P. 516)

For safety and security
WARNING
■Road accident cautions
Observe the following precautions to reduce the risk of death or serious injury:
●Pull your vehicle off the road, apply the parking brake, shift the shift lever to P, and
turn the hybrid system off.
●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 electrolyte
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 rear wheels raised. If the wheels con-
nected to the electric motor (traction motor) are on the ground when towing, the
motor may continue to generate electricity. This may cause a fire. ( P. 454)
●Carefully inspect the ground under the vehicl e. If you find that liquid has leaked onto
the ground, the fuel system may have been damaged. Leave the vehicle as soon as possible.

941-3. Theft deterrent system
GS450h_300h_OM_OM30F92E_(EE) ●
The intrusion sensor detects intruders or movement in the vehicle.
● The tilt sensor detects changes in vehicle inclination, such as when the vehicle
is towed away.
This system is designed to deter and pr event 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. 91)
■Canceling the intrusion sensor and tilt sensor
If you are leaving pets or other moving things inside the vehi cle, make sure to
stop the intrusion sensor and tilt sensor before setting the alarm, as th ey 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.
Press the switch again to re-enable
the intrusion sensor and tilt sensor.

Operation of each component
GS450h_300h_OM_OM30F92E_(EE)
■Electronic Key Battery-Saving Function
When battery-saving mode is set, battery de pletion is minimized by stopping the elec-
tronic key from receiving radio waves.
■Conditions affecting operation
The smart entry & start system uses weak ra dio waves. In the following situations, the
communication between the electronic key and the vehicle may be affected, preventing
the smart entry & start system, wireless re mote control and immobilizer system from
operating properly. (Ways of coping: P. 527)
●When the electronic key battery is depleted
●Near a TV tower, electric power plant, gas st ation, radio station, large display, airport or
other facility that gene rates strong radio waves or electrical noise
●When the electronic key is in contact wi th, or is covered by the following metallic
objects

●Do not place any objects in the front passenger footwell that could prevent the oper-
ation of the ottoman.
