Driving
IS300h_EE(OM53B95E)
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.

2284-3. Operating the lights and wipers
IS300h_EE(OM53B95E)
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
passengers and the loading condition of the vehicle to ensure that the headlights
do not interfere 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 cur-
rent status is displayed on the meters for a few seconds to show that AUTO mode
is activated/deactivated. (P. 1 1 9 )
Customization
Settings (e.g. light sensor sensitivity) can be changed.
(Customizable features: P. 581)
NOTICE
To prevent 12-volt battery discharge
Do not leave the lights on longer than necessary when the hybrid system is off.

2964-5. Using the driving support systems
IS300h_EE(OM53B95E)
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 control 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 operat-
ing. 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
indicate a malfunction.
Reactivation of the TRC/VSC systems
Even after the TRC/VSC systems have been turned off, turning the hybrid sys-
tem 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 over-
heating 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 normal within 10 minutes.

Use fluids that are appropriate to the prevailing outside temperatures.
•Engine oil
• Engine/power control unit coolant
•Washer fluid
Have a service technician inspect the condition of the 12-volt battery.
Have the vehicle fitted with four snow tires or purchase a set of tire
chains for the rear tires.
*
Ensure that all tires are the specified size and brand, and that chains match
the size of the tires.
*: Tire chains cannot be mounted on the 18-inch tires.
Perform the following according to the driving conditions:
Do not try to forcibly open a window or move a wiper that is frozen.
Pour warm water over the frozen area to melt the ice. Wipe away the
water immediately to prevent it from freezing.
To ensure proper operation of the climate control system fan, remove
any snow that has accumulated on the air inlet vents in front of the
windshield.
Check for and remove any excess ice or snow that may have accumu-
lated on the exterior lights, vehicle’s roof, chassis, around the tires or
on the brakes.
Remove any snow or mud from the bottom of your shoes before get-
ting in the vehicle.
Accelerate the vehicle slowly, keep a safe distance between you and the
vehicle ahead, and drive at a reduced speed suitable to road conditions.
Winter driving tips
Carry out the necessary preparations and inspections before driving the
vehicle in winter. Always drive the vehicle in a manner appropriate to the
