GMC 15919282 Automobile User Manual


 
Notice: Ignoring these steps
could result in costly damage to
the vehicle that would not be
covered by the warranty.
Trying to start the vehicle by
pushing or pulling it will not work,
and it could damage the vehicle.
1. Check the other vehicle.
It must have a 12-volt battery
with a negative ground system.
Notice: If the other vehicle’s
system is not a 12-volt system
with a negative ground, both
vehicles can be damaged. Only
use vehicles with 12-volt systems
with negative grounds to jump
start your vehicle.
2. Get the vehicles close enough
so the jumper cables can reach,
but be sure the vehicles are not
touching each other. If they are, it
could cause a ground connection
you do not want. You would not
be able to start your vehicle, and
the bad grounding could damage
the electrical systems.
To avoid the possibility of the
vehicles rolling, set the parking
brake firmly on both vehicles
involved in the jump start
procedure. Put an automatic
transmission in P (Park) or
a manual transmission in Neutral
before setting the parking brake.
If one of the vehicles is a
four-wheel-drive vehicle, be sure
the transfer case is not in Neutral.
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!
