GENERAL PROCEDURES
Battery Disconnect
WARNING: Batteries normally produce explosive gases which can cause personal injury.
Therefore, do not allow flames, sparks or lighted substances to come near the battery, always
shield your face and protect your eyes. Always provide ventilation. Failure to follow these
instructions may result in personal injury.
WARNING: To avoid accidental deployment and possible injury, the backup power supply
must be depleted before repairing or installing any front or side air bag supplemental restraint
system (SRS) components and before repairing, installing, adjusting or striking components
near the front or side air bag sensors, such as doors, instrument panel, console, door latches,
strikers, seats and hood latches. Failure to follow these procedures may result in personal
injury.
Refer to the appropriate vehicle shop manual to determine location of the front air bag sensors.
To deplete the backup power supply energy, disconnect the battery ground cable and wait at
least one minute. Be sure to disconnect auxiliary batteries and power supplies (if equipped).
Failure to follow these instructions may result in personal injury.
WARNING: When lifting a battery, excessive pressure on the end walls could cause acid
to spew through the vent caps, resulting in personal injury. Lift with a battery carrier or with
your hands on opposite corners. Failure to follow these instructions may result in personal
injury.
WARNING: Keep out of the reach of children. Batteries contain sulfuric acid. Avoid
contact with skin, eyes or clothing. Also, shield your eyes when working near the battery to
protect against possible splashing of the acid solution. In case of acid contact with the skin or
eyes, flush immediately with water for a minimum of 15 minutes and get prompt medical
attention. If acid is swallowed, call a physician immediately. Failure to follow these instructions
may result in personal injury.

may occur while the vehicle relearns its adaptive strategy. The vehicle may need to be driven to
relearn its strategy.
Disconnect the battery ground cable.
2. Disconnect the positive battery cable.
