UNDERSTANDING THE FEATURES OF YOUR VEHICLE 133 If the headlights are left on, or turned on, when the ignition is turned OFF, the headlights will automatically turn off after approximately eight minutes. NOTE: Battery saver mode is cancelled if the ignition is ON. Headlight Delay To aid in your exit, your vehicle is equipped with a headlight delay that will leave the headlights on for approximately 90 seconds. This delay is initiated when the ignition is turned OFF while the headlight switch is on, and then the headlight switch is cycled off. Headlight delay can be cancelled by either turning the headlight switch on then off, or by turning the ignition ON. 3 Dimmer Control Battery Saver To protect the life of your vehicle's battery, load shedding is provided for both the interior and exterior lights. If the ignition is OFF and any door is left ajar, or if the dimmer control is rotated upwards for approximately 10 minutes, the interior lights will automatically turn off.
