CAUTION : Disconnect the negative battery cable before removing or installing any electrical unit o r w hen a
tool or equipment could easily come in contact with exposed electrical terminals. Disconnecting this cable will
help prevent personal injury and damage to the vehicle. The ignition must also be in LOCK unless otherwise
noted.
