Subaru Ascent 2018-2026 Owner's Manual: Battery

WARNING

• Never expose the battery in your Subaru Ascent to open flames or sparks.

  The battery emits highly flammable gases that can ignite and cause an explosion if exposed to ignition sources.

• Always wear appropriate eye protection when working near the battery of your Subaru Ascent. In the event of an explosion, eye injuries can occur. Avoid leaning directly over the battery at any time.
• Battery electrolyte is a highly corrosive acid and must never come into contact with eyes, skin, clothing, or painted surfaces.

  If contact occurs, immediately rinse the affected area with plenty of clean water.

  If the acid enters the eyes, seek medical assistance without delay.

  If swallowed accidentally, drink a large amount of water or milk and obtain emergency medical attention immediately.

• To reduce the risk of accidental short circuits, remove rings, watches, and other metal jewelry before working on the battery. Never allow metal tools to simultaneously contact the positive terminal and any other metal part of your Subaru Ascent, as this can cause dangerous sparks.
• Keep children and unauthorized persons away from the battery at all times.
• Always charge the battery of your Subaru Ascent in a well-ventilated area to prevent the buildup of explosive gases.
• Battery terminals and related components contain lead and lead compounds, which are known to cause health risks. Always wash your hands thoroughly after handling battery components.

CAUTION

Do not exceed a charging current of 10 amperes when charging the battery of your Subaru Ascent, as higher current may reduce battery lifespan and cause damage.

Under normal conditions, the battery installed in your Subaru Ascent does not require regular checking of electrolyte levels or the addition of distilled water, as it is designed for maintenance-free operation.

NOTE

To prevent battery discharge, avoid using electrical systems such as lights, wipers, climate control, or seat heaters for extended periods when the engine is not running. Even when the ignition is in the "ACC" position, prolonged use of electrical equipment may drain the battery of your Subaru Ascent.
