WARNING:To reduce risk of electrical shock, always replace
the cover to the Power Distribution Box before reconnecting the
battery or refilling fluid reservoirs.
If your vehicle is equipped with an auxiliary battery,
disconnecting the primary under-hood battery DOES NOT remove
power from all circuits.
If the battery has been disconnected and reconnected, refer to the
Batterysection of theMaintenance and Specificationschapter.

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. When working near the
battery, always shield your face and protect your eyes. Always provide
proper ventilation.
WARNING:When lifting a plastic-cased battery, excessive
pressure on the end walls could cause acid to flow through the
vent caps, resulting in personal injury and/or damage to the vehicle or
battery. Lift the battery with a battery carrier or with your hands on
opposite corners.
WARNING:Keep batteries out of reach of children. Batteries
contain sulfuric acid. Avoid contact with skin, eyes or clothing.
Shield your eyes when working near the battery to protect against
possible splashing of acid solution. In case of acid contact with 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.
WARNING:Battery posts, terminals and related accessories
contain lead and lead compounds.Wash hands after handling.
For information on transmission operation after the battery has been
disconnected, refer toAutomatic transmission operationin the
Drivingchapter.
Auxiliary battery (if equipped)
Your vehicle may be equipped with a frame-mounted auxiliary battery
located on the passenger side frame rail, behind the front passenger
door. This auxiliary battery is connected to the auxiliary battery relay, so
it is not used to start the vehicle.
