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 the skin; ﬂush

immediately and thoroughly any con-

tacted areas with water, and get medical

help.

Unless directed otherwise, the ignition

and start switch must be in the OFF or

LOCK position, and all electrical loads

must be OFF before servicing any electri-

cal component. Disconnect the battery

ground cable to prevent an electrical

spark should a tool or equipment come in

contact with an exposed electrical termi-

nal. Failure to follow these precautions

may result in personal injury and/or dam-

age 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 lim-

ited OnStar® functionality in the event of a

main vehicle battery power disruption to

the VCIM (OnStar® module). Do not dis-

connect the main vehicle battery 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 disabled (sim-

ply opening the driver door should disable

RAP) before disconnecting power. Dis-

connecting 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 dam-

age the BUB. Once the BUB is activated,

it will stay on until it has completely dis-

charged. The BUB is not rechargeable

and, once activated, the BUB must be

replaced.
