Battery saver function
The purpose of this feature is to help prevent the battery from being discharged. The system automatically turns off the parking lamp when the key is removed (remote key) or when the driver turns the engine off (smart key) and opens the driver-side door.
With this feature, the parking lamps will turn off automatically if the driver parks on the side of road at night.
If necessary, to keep the lamps on when the engine is turned off, perform the following:
1) Open the driver-side door.
2) Turn the parking lamps OFF and ON again using the light switch on the steering
column.
Headlamp delay function
If the key is removed from the ignition switch or placed in the ACC position or the LOCK/OFF position with the headlamps ON, the headlamps (and/or parking lamps) remain on for about 5 minutes. However, if the driver’s door is opened and closed, the headlights are turned off after 15 seconds. Also, with the engine off if the driver's door is opened and closed, the headlamps (and/or parking lamps) are turned off after 15 seconds.
The headlamps (and/or parking lamps) can be turned off by pressing the lock button on the remote key or smart key twice or turning the light switch to the OFF or AUTO position.
You can activate or deactivate the Headlamp Delay function from the User Settings Mode (Light) on the LCD display (if equipped with supervision cluster).
For more details, refer to the "LCD Display" section in this chapter.
NOTICE
If the driver exits the vehicle through another door besides the driver door, the battery saver function does not operate and the headlamp delay function does not turn OFF automatically.
This may cause the battery to discharge. To avoid battery discharge, turn OFF the headlamps manually from the headlamp switch before exiting the vehicle.
