561-1. For safe use
IS300h_EE(OM53B95E)
When the sensors located at the back of the front bumper detect an impact
with a body, such as a pedestrian, which meets or exceeds the threshold
level while the vehicle is being driven within the operational speed range,
the system becomes operational and raises the rear portion of the hood.
Sensors

Lifters
Pop Up Hood
In the event of a frontal collision with a body, such as a pedestrian, the
Pop Up Hood system raises the rear portion of the hood to reduce the
possibility of a serious impact to the pedestrian’s head area by adding
clearance to the engine compartment.

Hybrid system features
Your vehicle is a hybrid vehicle. It has characteristics different from con-
ventional vehicles. Be sure you are closely familiar with the characteris-
tics of your vehicle, and operate it with care.
The hybrid system combines the use of a gasoline engine and an electric
motor (traction motor) according to driving conditions, improving fuel
efficiency and reducing exhaust emissions.

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).

Regenerative braking
In the following situations, kinetic energy is converted to electric energy and
deceleration force can be obtained in conjunction with the recharging of the
hybrid battery (traction battery).
The accelerator pedal is released while driving with the shift lever in D or S.
The brake pedal is depressed while driving with the shift lever in D or S.
EV indicator
Conditions in which the gasoline engine may not stop
The gasoline engine starts and stops automatically. However, it may not stop
automatically in the following conditions:
During gasoline engine warm-up
During hybrid battery (traction battery) charging
When the temperature of the hybrid battery (traction battery) is high or low
When the heater is switched on
Charging the hybrid battery (traction battery)
As the gasoline engine charges the hybrid battery (traction battery), the battery
does not need to be charged from an outside source. However, if the vehicle is
left parked for a long time the hybrid battery will slowly discharge. For this rea-
son, be sure to drive the vehicle at least once every few months for at least 30
minutes or 16 km (10 miles). If the hybrid battery becomes fully discharged and
you are unable to jump-start the vehicle with a 12-volt battery, contact any
authorized Lexus dealer or repairer, or another duly qualified and equipped pro-
fessional.
If the shift lever is in N, the hybrid battery (traction battery) will not be charged.
Always shift the shift lever to P when the vehicle is stopped. When driving in
heavy traffic, operate the vehicle with the shift lever in D or S to avoid dis-
charging the battery.
Charging the 12-volt battery
P. 552 The EV indicator comes on when the vehi-
cle is driven using only the electric motor
(traction motor) or the gasoline engine is
stopped.

821-2. Hybrid system
IS300h_EE(OM53B95E)
After the 12-volt battery has discharged or has been changed or removed
The gasoline engine may not stop even if the vehicle is being driven by the
hybrid battery (traction battery). If this continues for a few days, contact any
authorized Lexus dealer or repairer, or another duly qualified and equipped pro-
fessional.
Sounds and vibrations specific to a hybrid vehicle
There may be no engine sound or vibration even though the vehicle is able to
move. For safety, apply the parking brake and make sure to shift the shift lever to
P when parked.
The following sounds or vibrations may occur when the hybrid system is operat-
ing and are not a malfunction:
Motor sounds may be heard from under the vehicle.
Sounds may be heard from the hybrid battery (traction battery) behind the rear
seats when the hybrid system starts or stops.
Sounds from the hybrid system may be heard when the trunk lid is open.
Sounds may be heard from the hybrid transmission when the hybrid system
starts or stops.
Engine sounds may be heard when accelerating sharply.
Sounds may be heard due to regenerative braking when the brake pedal is
depressed.
Vibration may be felt when the gasoline engine starts or stops.
Cooling fan sounds may be heard from the air intake vents on the both sides of
the rear seatback.
Maintenance, repair, recycling, and disposal
Contact any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional regarding maintenance, repair, recycling and disposal. Do
not dispose of the vehicle yourself.
Customization
Settings (e.g. on/off operation of the EV indicator) can be changed.
