PRECAUTIONS
Warning: Batteries produce explo-
sive gases, contain corrosive acid, and
supply levels of electrical current high
enough to cause burns. Therefore, to re-
duce the risk of personal injury when
working near a battery: Always shield
your eyes and avoid leaning over the
battery whenever possible; do not ex-
pose the battery to open flames or
sparks; do not allow the battery electro-
lyte to contact the eyes or skin; flush im-
mediately and thoroughly any
contacted areas with water, and get
medical help.
Warning: Unless directed otherwise,
the ignition and start switch must be in
the OFF or LOCK position, and all elec-
trical loads must be OFF before servic-
ing any electrical component. Discon-
nect the battery ground cable to
prevent an electrical spark should a
tool or equipment come in contact with
an exposed electrical terminal. Failure
to follow these precautions may result
in personal injury and/or damage to the
vehicle or its components.
For vehicles equipped with OnStar®
(UE1) with Back Up Battery, the back up
battery is a redundant power supply to
allow limited OnStar® functionality in the
event of a main vehicle battery power dis-
ruption to the VCIM (OnStar® module).
Do not disconnect the main vehicle bat-
tery or remove the OnStar® fuse with the
ignition key in any position other than
OFF. Retained Accessory Power (RAP)
should be allowed to time out or be dis-
abled (simply opening the driver door
should disable RAP) before disconnecting
power. Disconnecting power to the
OnStar® module in any way while the
ignition is ON or with RAP activated may
cause activation of the OnStar® Back Up
Battery (BUB) system and will discharge
and permanently damage the BUB. Once
the BUB is activated, it will stay on until it
has completely discharged. The BUB is
not rechargeable and, once activated, the
BUB must be replaced.
