Daytime running light system

●

To make your vehicle more visible to other drivers, the parking lights turn on auto-

matically (at an increased intensity) whenever the hybrid system is started and the

parking brake is released. Daytime running lights are not designed for use at night.

●

Compared to turning on the headlights, the daytime running light system offers

greater durability and consumes less electricity, so it can help improve fuel econ-

omy.

■

Automatic headlight leveling system

The level of the headlights is automatically adjusted according to the number of pas-

sengers and the loading condition of the vehicle to ensure that the headlights do not

interfere with other road users.

The sensor may not function properly if an

object is placed on the sensor, or anything

that blocks the sensor is affixed to the wind-

shield.

Doing so interferes with the sensor detecting

the level of ambient light and may cause the

automatic headlight system to malfunction.
