SERVICE PROCEDURE
WARNING: Park vehicle on hard flat surface, turn the engine off, set the parking brake, and
block the wheels to prevent the vehicle from moving in both directions. Failure to do so may result
in property damage, personal injury, and / or death.

WARNING: If the vehicle must be raised, do not work under the vehicle supported only by
jacks. Jacks can slip or fall over, potentially resulting in property damage, personal injury, and / or
death.

WARNING: Always wear safe eye protection when performing vehicle maintenance. Failure
to do so may result in personal injury and / or death.

WARNING: Keep flames or sparks away from vehicle and do not smoke while servicing

disconnecting any electrical components. Always connect the ground cable last. Failure to do so
may result in property damage, personal injury, and / or death.
