Subaru Ascent 2018-2026 Owner's Manual: Replacing bulbs

WARNING

Lighting bulbs in your Subaru Ascent can become extremely hot during operation. Always switch off the lights and allow sufficient time for the bulbs to cool before attempting replacement. Failure to do so may result in burns or injury.

CAUTION

Always replace bulbs in your Subaru Ascent with new ones of the correct specified wattage. Installing bulbs with incorrect ratings may lead to overheating, electrical issues, or even fire hazards. Refer to the "Bulb chart" for proper specifications.

Headlights

Your Subaru Ascent is equipped with LED headlights. If a malfunction occurs, the LED headlight warning light will illuminate on the instrument panel.
