CAUTION
People suffering illness
Obtain medical advice and wear the seat belt in the proper way. (P. 3 8 )
When children are in the vehicle
Do not allow children to play with the seat belt. If the seat belt becomes
twisted around a child’s neck, it may lead to choking or other serious inju-
ries that could result in death.
If this occurs and the buckle cannot be unfastened, scissors should be used
to cut the belt.
Seat belt pretensioners
If the pretensioner has activated, the SRS warning light will come on. In
that case, the seat belt cannot be used again and must be replaced at any
authorized Lexus dealer or repairer, or another duly qualified and equipped
professional.
Adjustable shoulder anchor
Always make sure the shoulder belt is positioned across the center of your
shoulder. The belt should be kept away from your neck, but not falling off
your shoulder. Failure to do so could reduce the amount of protection in an
accident and cause death or serious injuries in the event of a sudden stop,
sudden swerve or accident. (P. 3 9 )
Seat belt damage and wear
Do not damage the seat belts by allowing the belt, plate, or buckle to be
jammed in the door.
Inspect the seat belt system periodically. Check for cuts, fraying, and
loose parts. Do not use a damaged seat belt until it is replaced. Damaged
seat belts cannot protect an occupant from death or serious injury.
Ensure that the belt and plate are locked and the belt is not twisted.
If the seat belt does not function correctly, immediately contact any autho-
rized Lexus dealer or repairer, or another duly qualified and equipped pro-
fessional.
Replace the seat assembly, including the belts, if your vehicle has been
involved in a serious accident, even if there is no obvious damage.
Do not attempt to install, remove, modify, disassemble or dispose of the
seat belts. Have any necessary repairs carried out by any authorized Lexus
dealer or repairer, or another duly qualified and equipped professional.
Inappropriate handling may lead to incorrect operation.

861-2. Hybrid system
GS450h_300h_OM_OM30D53E_(EE)
If a warning light comes on, a warning message is displayed, or the 12-volt
battery is disconnected
The hybrid system may not start. In that case, try to start the system again. If
the “READY” indicator does not come on, contact any authorized Lexus
dealer or repairer, or another duly qualified and equipped professional.
Running out of fuel
When the vehicle has run out of fuel and the hybrid system cannot be started,
refuel the vehicle with at least enough gasoline to make the low fuel level
warning light (P. 833) go off. If there is only a small amount of fuel, the
hybrid system may not be able to start. (The minimum amount of fuel to add
to make the low fuel level warning light go out is about 9.9 L [2.6 gal., 2.2
Imp.gal.], when the vehicle is on a level surface. This value may vary when
the vehicle is on a slope.)
Electromagnetic waves
High voltage parts and cables on the hybrid vehicles incorporate electro-
magnetic shielding, and therefore emit approximately the same amount of
electromagnetic waves as conventional gasoline powered vehicles or home
electronic appliances.
Your vehicle may cause sound interference in some third party-produced
radio parts.
Hybrid battery (traction battery)
The hybrid battery (traction battery) has a limited service life. The lifespan of
the hybrid battery (traction battery) can change in accordance with driving
style and driving conditions.
Declaration of conformity
This model conforms to hydrogen emissions according to regulation ECE100
(Battery electric vehicle safety).
