2008 GMC ENVOY hood open

Notice:If you leave your radio or other accessories
on during the jump starting procedure, they could
be damaged. The repairs would not be covered by
your warranty. Always turn off your radio and other
accessories when jump starting your vehicle.
3. Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the cigarette
lighter or the accessory power outlets, if equipped.
Turn off the radio and all lamps that are not
needed. This will avoid sparks and help to save
both batteries. And it could save the radio!
4. Open both hoods and locate the batteries. Find the
positive (+) and negative (−) terminals on each
battery. Your vehicle has a remote negative (−) jump
starting terminal. You should always use this
remote terminal instead of the terminal on the

on the front engine lift bracket on vehicles with the
4.2L L6 engine or the engine accessory drive bracket
for vehicles with the 5.3L V8 engine, and is marked
GND (Ground). SeeEngine Compartment Overview
on page 5-12for more information on location.
