GMC 2010 Canyon Crew Cab Owner's Manual page 320

Notice: If you leave the radio or other accessories
on during the jump starting procedure, they could
be damaged. The repairs would not be covered by
the warranty. Always turn off the radio and other
accessories when jump starting the 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 lamps that are not needed. This will
avoid sparks and help save both batteries. And it
could save the radio!
4. Open the hoods and locate the positive (+) and
negative (−) terminal locations on the other vehicle.
Your vehicle has a remote positive (+) and a remote
negative (−) jump starting terminal. See Engine
Compartment Overview on page 6-12 for more
information on the terminal locations.

WARNING:
{
Using a match near a battery can cause battery
gas to explode. People have been hurt doing this,
and some have been blinded. Use a flashlight if
you need more light.
Be sure the batteries have enough water. You do
not need to add water to the ACDelco
(or batteries) installed in your new vehicle. But if a
battery has filler caps, be sure the right amount of
fluid is there. If it is low, add water to take care of
that first. If you do not, explosive gas could be
present.
Battery fluid contains acid that can burn you.
Do not get it on you. If you accidentally get it in
your eyes or on your skin, flush the place with
water and get medical help immediately.
