CAUTION Carry a live air bag with the bag and trim cover pointed away from your body. An accidental deployment will then deploy with minimal chance of injury. Place a live air bag on a bench or other surface with the trim cover up.

Install the passenger side bolt first.
CAUTION Never probe the connectors on the air bags. Doing so may result in air bag deployment, which could result in personal injury. Carry a live air bag with the bag and trim cover pointed away from your body. An accidental deployment will then deploy with a minimal chance of injury.

CAUTION Never open, service or drain the radiator or cooling system when hot; serious burns can occur from the steam and hot coolant. Also, when draining engine coolant, keep in mind that cats and dogs are attracted to ethylene glycol antifreeze and could drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantities. Always drain coolant into a sealable container. Coolant should be reused unless it is contaminated or is several years old.
