Vehicle Care
1. Check the other vehicle. It must
have a 12
‐
volt battery with a
negative ground system.
Notice:
Only use a vehicle that
has a 12-volt system with a
negative ground for jump
starting. If the other vehicle does
not have a 12-volt system with a
negative ground, both vehicles
can be damaged.
2. Get the vehicles close enough
so the jumper cables can reach,
but be sure the vehicles are not
touching each other. 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 the automatic
transmission in P (Park) or a
manual transmission in
N (Neutral) before setting the
parking brake. If you have a
four-wheel-drive vehicle, be sure
the transfer case is in a drive
gear, not in N (Neutral).
Notice:
If any accessories are left
on or plugged in during the jump
starting procedure, they could be
damaged. The repairs would not
be covered by the vehicle
warranty. Whenever possible,
turn off or unplug all accessories
on either vehicle 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 the lamps that are not
needed.
This avoids sparks and helps
save both batteries. It could
save the radio!
4. Open the hood on the other
vehicle and locate the
positive (+) and negative (
−
)
terminal locations on that
vehicle.
Your vehicle has a remote
positive (+) and a remote
negative (
−
) jump starting
terminal. You should always use
these remote terminals instead
of the terminals on the battery.
