WARNING!
Do not allow vehicles to touch each other as
this could establish a ground connection and
personal injury could result.
Jump-Starting Procedure
WARNING!
Failure to follow this procedure could result in
personal injury or property damage due to
battery explosion.
CAUTION!
Failure to follow these procedures could result
in damage to the charging system of the
booster vehicle or the discharged vehicle.
1. Connect the positive (+) end of the jumper
cable to the positive (+) post of the discharged
vehicle.
2. Connect the opposite end of the positive (+)
jumper cable to the positive (+) post of the
booster battery.
3. Connect the negative end (-) of the jumper
cable to the negative (-) post of the booster
battery.
4. Connect the opposite end of the negative (-)
jumper cable to a good engine ground (ex-
posed metal part of the discharged vehicle’s
engine) away from the battery and the fuel
injection system.
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 min-
utes, 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 engine ground of the vehicle with the
discharged battery.
7. Disconnect the negative end (-) of the
jumper cable from the negative (-) post of the
booster battery.
8. Disconnect the opposite end of the positive
(+) jumper cable from the positive (+) post of
the booster battery.
9. Disconnect the positive (+) end of the
jumper cable from the positive (+) post of the
discharged vehicle.
If frequent jump-starting is required to start your
vehicle you should have the battery and charg-
ing system inspected at your authorized dealer.
CAUTION!
Accessories that can be 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, the vehicle’s battery will dis-
charge sufficiently to degrade battery life
and/or prevent the engine from starting.
