from the remote negative (-) post of the vehicle with
the discharged battery.
2. Disconnect the opposite end of the negative (-) jumper
cable from the negative (-) post of the booster battery.
3. Disconnect the positive end (+) of the jumper cable
from the positive (+) post of the booster battery.

cable from the remote positive (+) post of the dis-

If frequent jump-starting is required to start your vehicle
you should have the battery and charging system in-
spected at your authorized dealer.
CAUTION!
Accessories plugged into the vehicle power outlets
draw power from the vehicle’s battery, even when not
in use (i.e., cellular phones, etc.). Eventually, if
plugged in long enough without engine operation,
the vehicle’s battery will discharge sufficiently to
degrade battery life and/or prevent the engine from
starting.
