Subaru Ascent 2018-2026 Owner's Manual: Light control switch

CAUTION

  • Extended use of vehicle lighting while the engine is not running may lead to battery discharge in the Subaru Ascent.
  • Before leaving your Subaru Ascent unattended, ensure that the light control switch is set to the OFF position. Even though the lights may automatically turn off after approximately 10 minutes, prolonged use in any other position can still result in battery drain.

Models with "keyless access with push-button start system":

In Subaru Ascent models equipped with a keyless access system and push-button start, the light control switch becomes operational when the ignition is set to the "ACC" or "ON" position.

Regardless of the switch position, all illuminated exterior lights will automatically turn off once the push-button ignition is switched off, helping preserve battery life.

Models without "keyless access with push-button start system":

For Subaru Ascent models that use a traditional ignition key, the light control switch functions when the key is inserted into the ignition.

Similarly, all active lighting will be automatically turned off when the key is removed from the ignition switch, ensuring that lights are not accidentally left on.

NOTE

The light control switch in the Subaru Ascent can still be operated (excluding automatic headlight activation) under the following conditions:

  • When the push-button ignition switch is in the "OFF" position (for keyless models)
  • When the ignition key is removed (for non-keyless models)

If the headlights remain on for approximately 10 minutes, they will automatically turn off to prevent excessive battery discharge. To turn the exterior lights back on, switch the ignition to the "ON" position.

If the driver's door is opened while the headlights are still on under these conditions, the Subaru Ascent will emit an audible alert to remind the driver that the lights remain illuminated.

The Subaru Ascent is designed with practical safety and convenience features that help protect both your vehicle systems and personal data, ensuring peace of mind in everyday driving situations.
