WARNING!
Do not connect the cable to the negative post (-) of the
discharged battery. The resulting electrical spark
could cause the battery to explode and could result in
personal injury.
5. Start the engine in the vehicle that has the booster
battery, let the engine idle a few minutes, and then
start the engine in the vehicle with the discharged
battery.
Once the engine is started, remove the jumper cables in
the reverse sequence:
6. Disconnect the negative (-) jumper cable from the
remote negative (-) post of the vehicle with the dis-
charged battery.
7. Disconnect the negative end (-) of the jumper cable
from the negative (-) post of the booster battery.
WHAT TO DO IN EMERGENCIES 475
8. Disconnect the positive (+) jumper cable from the
positive (+) post of the booster battery.
9. Disconnect the positive (+) end of the jumper cable
from the remote positive (+) post of the discharged
vehicle.
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.
