GMC 2014 Terrain Owner's Manual page 286

If the jumper cables are
connected or removed in the
wrong order, electrical shorting
may occur and damage the
vehicle. The repairs would not be
covered by the vehicle warranty.
Always connect and remove the
jumper cables in the correct order,
making sure that the cables do
not touch each other or other
metal.
1. Remote Positive (+) Terminal
2. Remote Negative ( ) Terminal
1. The vehicle used to jump start
must have 12-volt battery with a
negative ground.
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.
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.
