Don't panic. Determine if it's smoke or steam. Pull off the road immediately. Unlock power door locks -- in case electricity quits. Turn the ignition OFF -- to shut off fuel pump and spark plugs. Pull the hood release -- so firefighters can put out fire. Get everyone out of the car. Call the fire department. Leave the sunroof, windows and doors closed. Don't open the hood -- starve the fire of oxygen. Don't fight the fire yourself. Water won't put out gasoline or electrical fires. Only TYPE B and TYPE C fire extinguisher. Dry chemical is most effective, but leaves corrosive residue. If the fire is under the car: Get out and stay away. The gas tank could explode.
