GMC 2008 Yukon XL Denali, Owner'S Manual

Page: 379 / 502

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. Turn off the
radio and all the lamps that are not needed. This
avoids sparks and helps save both batteries. And it
could save the radio!
4. Open the hood on the other vehicle and locate the
positive (+) and negative (
−
) terminal locations on
that vehicle.
Your vehicle has a remote positive (+) jump starting
terminal and a remote negative (
−
) jump starting
terminal. You should always use these remote
terminals instead of the terminals on the battery.
If the vehicle has a remote positive (+) terminal, it is
located under a red plastic cover at the positive
battery post. To uncover the remote positive (+)
terminal, open the red plastic cover.
The remote negative (
−
) terminal is a stud located
on the right front of the engine, where the
negative battery cable attaches.
See Engine Compartment Overview on page 5-12
for more information on the location of the remote
positive (+) and remote negative (
−
) terminals.
