SERVICE PROCEDURE
WARNING: Park vehicle on hard flat surface, turn the engine off, set the parking brake, and
install wheel chocks to prevent the vehicle from moving in both directions. Failure to comply 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 comply may result in personal injury and / or death.

WARNING: Keep flames or sparks away from vehicle and do not smoke while servicing the
vehicle’s batteries. Batteries expel explosive gases. Failure to comply may result in property
damage, personal injury, and / or death.

WARNING: Remove the ground cable from the negative terminal of the battery box before
disconnecting any electrical components. Always connect the ground cable last. Failure to comply
may result in property damage, personal injury, and / or death.

NOTE: It is recommended the technician read these instructions thoroughly prior to performing this
procedure.
