851-2. Hybrid system

GS450h_300h_OM_OM30D53E_(EE)
For safety and security
There are air intake vents on the
both sides of the rear seatback
for the purpose of cooling the
hybrid battery (traction battery).
If the vents become blocked, the
hybrid battery may overheat,
leading to a reduction in hybrid
battery output.
When a certain level of impact is detected by the impact sensor, the
emergency shut off system blocks off the high voltage current and
stops the fuel pump to minimize the risk of electrocution and fuel
leakage. If the emergency shut off system activates, your vehicle
will not restart. To restart the hybrid system, contact any authorized
Lexus dealer or repairer, or another duly qualified and equipped
professional.
A message is automatically displayed when a malfunction occurs in
the hybrid system or an improper operation is attempted.
If a warning message is shown
on the multi-information display,
read the message and follow the
instructions.

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).
1001-3. Theft deterrent system
GS450h_300h_OM_OM30D53E_(EE)
The intrusion sensor detects intruders or movement in the vehi-
cle.
The tilt sensor detects changes in vehicle inclination, such as
when the vehicle is towed away. (if equipped)
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. 97)
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 set-
ting the alarm, as they will respond to movement inside the vehi-
cle.
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.
NOTICE
To ensure the system operates correctly
Do not modify or remove the system. If modified or removed, the proper
operation of the system cannot be guaranteed.
