411-1. For safe use
GS450h_U (OM30D01U)

For safety and security
Your vehicle is equipped with ADVANCED AIRBAGS designed based
on the US motor vehicle safety standards (FMVSS208). The airbag sen-
sor assembly (ECU) controls airbag deployment based on information
obtained from the sensors etc. show n in the system components diagram
above. This information includes crash severity and occupant information.
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 occupants.
CAUTION
■SRS airbag precautions
Observe the following precautions regarding the SRS airbags.
Failure to do so may caus e death or serious injury.
●The driver and all passengers in the vehi cle 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
serious injury especially if the driver is very close to the airbag. The National
Highway Traffic Safety Admi nistration (NHTSA) advises:
Since the risk zone for the driver’s airbag is the first 2 - 3 in. (50 - 75 mm) of
inflation, placing yourself 10 in. (250 mm) 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 10 in. (250 mm) 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 comfortably.
• Slightly recline the back of the seat. Although vehicle designs vary, many drivers can achieve the 10 in. (250 mm)
distance, even with the driver seat all the way 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 fi rm, non-slippery cushion, or raise the
seat if your vehicle has that feature.
• If your steering wheel is adjustable, ti lt it downward. This points the airbag
toward your chest instead of your head and neck.
The seat should be adjusted as reco mmended by NHTSA above, while still
maintaining control of the foot pedals, steering wheel, and your view of the
instrument panel controls.

For safety and security
CAUTION
■SRS airbag precautions
●Do not allow a child to stand in front of the
SRS front passenger airbag unit or sit on
the knees of a front passenger.
●Do not allow the front seat occupants to
hold items on their knees.
●Do not lean against the door, the roof side
rail or the front, side and rear pillars.
●Do not allow anyone to kneel on the pas-
senger seats 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, steer-
ing wheel pad, lower portion of the instru-
ment panel and door of the glove box.
These items can become projectiles when
the SRS driver, front passenger and knee
airbags deploy.

GS450h_U (OM30D01U)

For safety and security
CAUTION
■High voltage precautions
The vehicle has high voltage DC and AC systems as well as a 12-volt system. DC
and AC high voltage is very dangerous and can cause severe burns and electric
shock that may result in death or serious injury.
●Never touch, disassemble, remove or re place the high voltage parts, cables or
their connectors.
●The hybrid system will become hot after starting as the system uses high voltage.
Be careful of both the high voltage and the high temperature, and always obey
the caution labels attached to the vehicle.
■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 flui d 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 imme diate 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
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. 7 0 4 )
●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.
●Never try to open the service plug access
hole located behind the rear seats. The ser-
vice plug is used only when the vehicle is
serviced and is subject to high voltage.

3-2. Opening, closing and locking the doors and trunk
■Conditions affecting operation
The smart access system with push-button start uses weak radio waves. In the follow-
ing situations, the communication between the electronic key and the vehicle may be
affected, preventing the smar t access system with push-button start, wireless remote
control and immobilizer system from operating properly. (Ways of coping: P. 76 7 )
●When the electronic ke y battery is depleted
●Near a TV tower, electric power plant, gas station, radio station, large display, air-
port or other facility that generates strong radio waves or electrical noise
●When carrying a portable radio, cellular phone, cordless phone or other wireless
communication device
●When the electronic key is in contact with, or is covered by the following metallic
objects
• Cards to which aluminum foil is attached
• Cigarette boxes that have aluminum foil inside
• Metallic wallets or bags
•Coins
• Hand warmers made of metal
• Media such as CDs and DVDs
●When other wireless keys (that emit radio waves) are being used nearby
●When carrying the electronic key togeth er with the following devices that emit
radio waves
• Another vehicle’s electronic key or a wireless key that emits radio waves
• Personal computers or person al digital assistants (PDAs)
• Digital audio players
• Portable game systems
●If window tint with a metallic content or metallic objects are attached to the rear
window

3-3. Adjusting the seats
■Auto return function when entering the vehicle (driver’s seat only)
When either of the following actions has been performed, the steering
wheel will move toward the driver and seat will move forward:• The power switch has been turned to ACCESSORY mode.
• The driver’s seat belt has been fastened.
■When driving position memory is linked with door unlock operation
If the driver’s door is opened, the driver’s seat will move toward the memorized posi-
tion but stop slightly beforehand to allow easy access to the vehicle.
Turning the power switch to ACCESSORY or ON mode, or fastening the driver’s
seat belt moves the seat full y into the memorized position.
■Operating the driving position memory after turning the power switch off
Driver’s seat:
Memorized seat positions can be activated up to 180 seconds after the driver’s door
is opened and another 60 seconds after it is closed again. Memorized steering
wheel position can be activated by pressing the power switch.
Front passenger’s seat:
Memorized positions can be activated up to 180 seconds after the front passenger’s
door is opened by pressing button “1”, “2” or “3”.
■Correct seat position
When the seat is in the most forward or most backward position, and the seat is
being moved in those directions, the system may not correctly recognize the current
position and the memorized position will not be correctly recalled.
■The auto away function for exiting the driver’s seat
If the seat is already close to the rearmost position, the auto away function may not
operate when the driver exits the vehicle.
■Customization
The distance that the driver’s seat moves backward during the auto away function
can be changed. (Customizable features: P. 8 0 7 )
CAUTION
■Seat adjustment caution
Take care during seat adjustment so that the seat does not strike the rear passen-
ger or squeeze your body against the steering wheel.
