GMC Terrain Denali 2015 Owner's Manual page 286

Caution
If the other vehicle does not have
a 12-volt system with a negative
ground, both vehicles can be
damaged. Only use a vehicle that
has a 12-volt system with a
negative ground for jump starting.
2. The vehicles should be close
enough for the jumper cables to
reach, but the vehicles should
not be touching. Touching could
cause grounding and possible
electrical system damage.
Put both vehicles in P (Park) and
set the parking brake firmly.
3. Unplug accessories plugged into
the cigarette lighter or the
accessory power outlet. Turn off
the radio and all lamps that are
not needed. Turn off the ignition
on both vehicles.
4. Locate the positive (+) and
negative ( ) terminals on both
vehicles. Some vehicles have
remote jump starting terminals.
Warning
An electric fan can start up even
when the engine is not running
and can injure you. Keep hands,
clothing and tools away from any
underhood electric fan.
5. The remote positive (+)
terminal (1) is located on the
underhood fuse block, on the
driver side. Lift the red cap to
uncover the terminal.
The remote negative ( )
terminal (2) is a stud behind the
metal tab stamped with GND ( )
near the driver side strut tower.
6. The jumper cables should be in
good working condition with no
loose or missing insulation. The
vehicles could be damaged if
they are not.
Vehicle Care
7. Connect the red positive (+)
cable to the positive (+) terminal
on the vehicle with the dead
battery. Use a remote
positive (+) terminal if the
vehicle has one.
8. Do not let the other end touch
metal. Connect it to the
positive (+) terminal of the good
battery. Use a remote
positive (+) terminal if the
vehicle has one.
9. Connect the black negative ( )
cable to the negative ( ) terminal
of the good battery. Use a
remote negative ( ) terminal if
the vehicle has one.
Do not let the other end touch
anything until the next step. The
other end of the negative ( )
cable does not go to the dead
battery. It goes to a heavy,
unpainted metal engine part or
to a remote negative ( ) terminal
on the vehicle with the dead
battery.
