Caution: Batteries produce explosive gases. Batteries contain corrosive acid. Batteries supply levels of electrical current high enough to cause burns. Therefore, in order to reduce the risk of personal injury while working near a battery, observe the following guidelines:

   • Always shield your eyes.
   • Avoid leaning over the battery whenever possible.
   • Do not expose the battery to open flames or sparks.
   • Do not allow battery acid to contact the eyes or the skin.
      - Flush any contacted areas with water immediately and thoroughly.
      - Get medical help.

The battery tray and the retainer should be clean and free of corrosion before the battery is installed.

The tray should be in good condition so the tray can hold the heavy battery securely and level. Be certain that there are no parts in the tray before installing the battery.

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

Prevent the battery from shaking in the tray by tightening the retainer to specifications.

Tighten
Tighten the battery hold down retainer nut to 17 N·m (13 lb ft).
