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 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.
The negative (–) terminal is located under a
black tethered cap on the battery. See Engine
Compartment Overview on page 5-14 for more
information on location. Flip the caps up to access
the positive (+) and negative (–) terminals.
