GMC 2007 Automobile User Manual


 
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 transaxle in PARK (P) or
a manual transaxle in NEUTRAL before setting
the parking brake.
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
outlet. 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 batteries. Find
the positive (+) and negative () terminal
locations on each vehicle. Your vehicle’s
positive (+) terminal is located under a
red tethered cap on the battery. See Engine
Compartment Overview on page 276 for more
information on location.
Flip the cap up to access the positive (+)
terminal.
{CAUTION:
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.
