  • Keep gasoline away from rubber or leather parts.


  1. DISCHARGE FUEL SYSTEM PRESSURE

    CAUTION:


    • Do not disconnect any part of the fuel system until you have discharged the fuel system pressure.

    • Even after discharging the fuel pressure, place a cloth or equivalent over fittings as you separate them to reduce the risk of fuel spray on yourself or in the engine compartment.


    1. Disconnect the cable from the negative (-) battery terminal.

      CAUTION:

      Wait at least 90 seconds after disconnecting the cable from the negative (-) battery terminal to prevent airbag and seat belt pretensioner activation.
