Driving
IS300h_EE(OM53C61E)
CAUTION
■When driving on slippery road surfaces
Be careful of downshifting and sudden acceleration, as this could result in the vehicle
skidding to the side or spinning.
NOTICE
■Hybrid battery (traction battery) charge
If the shift lever is in N, the hybrid battery (traction battery) will not be charged even
when the engine is running. Therefore, if the vehicle is left with the shift lever in N for a
long period of time, the hybrid battery (traction battery) will discharge, and this may
result in the vehicle not being able to start.

IS300h_EE(OM53C61E)
■Light reminder buzzer
A buzzer sounds when the power switch is turned off or turned to ACCESSORY mode
and the driver’s door is opened while the lights are turned on.
■Automatic headlight leveling system
The level of the headlights is automatically adjusted according to the number of passen-
gers and the loading condition of the vehicle to ensure that the headlights do not inter-
fere with other road users.
■Operation guide display (vehicles with rain-sensing windshield wipers only)
When the headlight switch is operated to and from the “AUTO” position, the current sta-
tus is displayed on the meters for a few seconds to show that AUTO mode is activated/
deactivated. (→P. 1 1 8 )
■Customization
Settings (e.g. light sensor sensitivity) can be changed.
(Customizable features: →P. 5 7 9 )
NOTICE
■To prevent 12-volt battery discharge
Do not leave the lights on longer than necessary when the hybrid system is off.

Driving
IS300h_EE(OM53C61E)
■When the 12-volt battery is disconnected
The steering wheel may move from its straight forward position, but this will be corrected
automatically when driving.
■Sounds and vibrations caused by the ABS, brake assist, TRC, VSC, hill-start assist con-
trol systems
●A sound may be heard from the engine compartment when the brake pedal is
depressed repeatedly, when the hybrid system is started or just after the vehicle begins
to move. This sound does not indicate that a malfunction has occurred in any of these
systems.
●Any of the following conditions may occur when the above systems are operating.
None of these indicates that a malfunction has occurred.
• Vibrations may be felt through the vehicle body and steering.
• A motor sound may be heard after the vehicle comes to a stop.
■EPS operation sound
When the steering wheel is operated, a motor sound may be heard. This does not indi-
cate a malfunction.
■Reactivation of the TRC/VSC systems
Even after the TRC/VSC systems have been turned off, turning the hybrid system off and
then on again will automatically reactivate the TRC/VSC systems.
■Reactivation of the TRC system linked to vehicle speed
When only the TRC system is turned off, the TRC system will turn on when vehicle speed
increases. However, when both TRC and VSC systems are turned off, the systems will
not turn on even when vehicle speed increases.
■Reduced effectiveness of the EPS system
The effectiveness of the EPS system is reduced to prevent the system from overheating
when there is frequent steering input over an extended period of time. The steering
wheel may feel heavy as a result. Should this occur, refrain from excessive steering input
or stop the vehicle and turn the hybrid system off. The EPS system should return to nor-
mal within 10 minutes.

the exterior lights, vehicle’s roof, chassis, around the tires or on the brakes.
