681-1. For safe use
IS300h_EE(OM53B95E)
CAUTION
Child restraint precautions
For effective protection in automobile accidents and sudden stops, a child
must be properly restrained, using a seat belt or child restraint system depend-
ing on the age and size of the child. Holding a child in your arms is not a sub-
stitute for a child restraint system. In an accident, the child can be crushed
against the windshield, or between you and the vehicle’s interior. This may
cause death or serious injury to the child in the event of a sudden stop, sudden
swerve or accident.
Lexus strongly urges the use of a proper child restraint system that conforms
to the size of the child, installed on the rear seat. According to accident statis-
tics, the child is safer when properly restrained in the rear seat than in the
front seat.
Never use a rear-facing child restraint system on the front passenger seat
when the airbag manual on-off switch is on. (P. 5 4 )
In the event of an accident, the force of the rapid inflation of the front passen-
ger airbag can cause death or serious injury to the child.
A forward-facing child restraint system may be installed on the front passen-
ger seat only when it is unavoidable. A child restraint system that requires a
top tether strap should not be used in the front passenger seat since there is no
top tether strap anchor for the front passenger seat. Adjust the seatback as
upright as possible and always move the seat as far back as possible because
the front passenger airbag could inflate with considerable speed and force.
Otherwise, the child may be killed or seriously injured.
Do not allow the child to lean his/her head or any part of his/her body against
the door or the area of the seat, front, center and rear pillars or roof side rails
from which the SRS side airbags or SRS curtain shield airbags deploy even if
the child is seated in the child restraint system. It is dangerous if the SRS side
airbags and curtain shield airbags inflate, and the impact could cause death or
serious injury to the child.
Make sure you have complied with all installation instructions provided by
the child restraint manufacturer and that the system is properly secured. If it is
not secured properly, it may cause death or serious injury to the child in the
event of a sudden stop, sudden swerve or accident.

801-2. Hybrid system
IS300h_EE(OM53B95E)
When stopped/during start off
The gasoline engine stops when the vehicle is stopped. During start off,
the electric motor (traction motor) drives the vehicle. At slow speeds or
when traveling down a gentle slope, the engine is stopped and the elec-
tric motor (traction motor) is used.
During normal driving
The gasoline engine is predominantly used. The electric motor (trac-
tion motor) charges the hybrid battery (traction battery) as necessary.
When accelerating sharply
When the accelerator pedal is depressed heavily, the power of the
hybrid battery (traction battery) is added to that of the gasoline engine
via the electric motor (traction motor).
When braking (regenerative braking)
The electric motor (traction motor) charges the hybrid battery (traction
battery).

This display changes to a tachometer depending on the drive mode, and can be
set to show the tachometer in any drive mode on the settings display. (P.
119)
Outside temperature
Displays the outside temperature within the range of -40°C (-40°F) to 50°C
(122°F). Low outside temperature indicator comes on when the ambient tem-
perature is 3°C (37°F) or lower.

Tachometer
Hybrid System Indicator switches to the tachometer when driving mode is in
sport mode.
The settings of the tachometer display can be changed on the multi-information
display. (P. 1 1 9 )
Engine speed
On hybrid vehicles, engine speed is precisely controlled in order to help improve
fuel efficiency and reduce exhaust emissions etc.
There are times when the engine speed that is displayed may differ even when
vehicle operation and driving conditions are the same.
Outside temperature display
In the following situations, the correct outside temperature may not be displayed,
or the display may take longer than normal to change.
When stopped, or driving at low speeds (less than 20 km/h [12 mph])
When the outside temperature has changed suddenly (at the entrance/exit of a
garage, tunnel, etc.)
Pop-up display
In some situations, such as when a switch operation is performed, a pop-up dis-
play, such as the operating methods of the headlight switch, will be temporarily
displayed on the multi-information display or the odometer/trip meter screen (F
SPORT models only).
The pop-up display function can be set on/off. (P. 119)
Liquid crystal display
Small spots or light spots may appear on the display. This phenomenon is charac-
teristic of liquid crystal displays, and there is no problem continuing to use the
display.
Customization
The meter display can be customized on the multi-information display. (P.
116)
NOTICE
To prevent damage to the engine and its components
Do not let the indicator needle of the tachometer enter the red zone, which
indicates the maximum engine speed.
The engine may be overheating if the engine coolant temperature gauge is in
the red zone (H). In this case, immediately stop the vehicle in a safe place, and
check the engine after it has cooled completely. (P. 555)
