■SRS airbag precautions
Observe the following precautions regarding the SRS airbags.
Failure to do so may cause death or serious injury.
●The driver and all passengers in the vehicle must wear their seat belts properly.
The SRS airbags are supplemental devices to be used with the seat belts.
●The SRS driver airbag deploys with considerable force, and can cause death or seri-
ous injury especially if the driver is very close to the airbag.
Since the risk zone for the driver’s airbag is the first 50 - 75 mm (2 - 3 in.) of inflation,
placing yourself 250 mm (10 in.) from your driver airbag provides you with a clear
margin of safety. This distance is measured from the center of the steering wheel to
your breastbone. If you sit less than 250 mm (10 in.) away now, you can change your
driving position in several ways:
• Move your seat to the rear as far as you can while still reaching the pedals com-
fortably.
• Slightly recline the back of the seat.
Although vehicle designs vary, many drivers can achieve the 250 mm (10 in.) dis-
tance, even with the driver seat all the wa y forward, simply by reclining the back of
the seat somewhat. If reclining the back of your seat makes it hard to see the road,
raise yourself by using a firm, non-slippery cushion, or raise the seat if your vehicle
has that feature.
• If your steering wheel is adjustable, tilt it downward. This points the airbag toward
your chest instead of your head and neck.
The seat should be adjusted as recommend ed above, while still maintaining control
of the foot pedals, steering wheel, and yo ur view of the instrument panel controls.

■SRS airbag precautions
●Do not hang coat hangers or other hard objects on the coat hooks. All of these items
could become projectiles and may cause death 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 the 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. 5 3 4 )

■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. 4 7 0 )
●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.

931-3. Theft deterrent system
1
GS450h_300h_OM_OM30F00E_(EE)
For safety and security
●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. 9 0 )
■Canceling the intrusion sensor and tilt sensor
If you are leaving pets or other moving things inside the vehicle, make sure to
stop 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.
Press the switch again to re-enable
the intrusion sensor and tilt sensor.

■Electronic Key Battery-Saving Function
When battery-saving mode is set, battery depletion is minimized by stopping the elec-
tronic key from receiving radio waves.
■Conditions affecting operation
The smart entry & start system uses weak radio waves. In the following situations, the
communication between the electronic key and the vehicle may be affected, preventing
the smart entry & start system, wireless remote control and immobilizer system from
operating properly. (Ways of coping: →P. 5 4 8 )
●When the electronic key battery is depleted
●Near a TV tower, electric power plant, gas station, radio station, large display, airport or
other facility that generates strong radio waves or electrical noise
●When the electronic key is in contact wi th, or is covered by the following metallic
objects
