2. Park both vehicles close enough
so that the jumper cables can
reach both vehicles' positive (+)
and negative (−) terminals. The
vehicles must not touch each
other. It could cause an unwanted
ground connection that could
damage both vehicles' electrical
systems.
Put both vehicles in P for an
automatic transmission or electric
drive unit. For a manual
transmission, place the vehicle in
neutral and apply the parking
brake.
3. Turn off both vehicles. Turn off the
radio, all lamps, and accessories
that are not needed in both
vehicles. Unplug accessories
from the accessory power outlets.
This avoids sparks and helps
save both batteries and
accessories.
4. Locate the positive (+) and
negative (−) terminals on the
vehicle with the run‐down battery.
5. Locate the positive (+) and
negative (−) battery terminals on
the vehicle. The access cover is
under the load floor access cover
in the rear cargo area. Open the
access cover for the positive (+)
terminal cover (A) and the
negative (−) terminal cover (B).
6. Check that the jumper cables do
not have loose or missing
insulation or a shock could result
and the vehicles could be
damaged.
Before connecting the jumper
cables, here are some basic
things to know. Positive (+)
Vehicle care
jumper cable goes to positive (+)
battery terminal or a remote
positive (+) terminal if available.
Negative (−) jumper cable goes to
remote negative (−) terminal if
available, or a heavy, unpainted
metal engine part or a solid engine
ground on the vehicle with the run‐
down battery.
Do not connect positive (+) to
negative (−) or there will be a short
that may damage the battery or
other parts of the vehicle. Do not
connect the negative (−) cable to
the negative (−) terminal on the
rundown battery because this can
cause sparks.
Connecting the jumper cables
1. Connect the red positive (+)
jumper cable to the positive (+)
terminal of the other vehicle with
the run‐down battery. Use
a remote positive (+) terminal if
available. Do not let the other end
touch metal.
