Daytime running light system

●

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

matically (at a reduced intensity) whenever the engine 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

economy.

Automatic light off system

●

When the headlights are on: The headlights and tail lights turn off 30 seconds

after a door is opened and closed if the °ENGINE START STOP± switch has

been switched to ACCESSORY or OFF mode.

●

When only the tail lights are on: The tail lights turn off automatically if the

°ENGINE START STOP± switch is switched to ACCESSORY or OFF mode

and driver²s door is opened.

To turn the lights on again, turn the °ENGINE START STOP± switch to IGNITION

ON mode, or turn the light switch off once and then back to the

or

position.

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.
