Caution (Continued)
warranty. Whenever possible, turn off or
unplug all accessories on either vehicle
when jump starting.
4. Turn the ignition off on both vehicles. Unplug unnecessary accessories plugged
into the accessory power outlets. Turn
off the radio and all the lamps that are
not needed. This will avoid sparks and
help save both batteries. And it could
save the radio!
5. Open the hood on the other vehicle and locate the positive (+) and negative (−)
terminal locations on that vehicle.
{Warning
An electric fan can start up even when
the engine is not running and can injure
you. Keep hands, clothing, and tools
away from any underhood electric fan.
{Warning
Using a match near a battery can cause
battery gas to explode. People have been
hurt doing this, and some have been
blinded. Use a flashlight if you need
more light.
Battery fluid contains acid that can burn
you. Do not get it on you. If you
accidentally get it in your eyes or on
your skin, flush the place with water and
get medical help immediately.
{Warning
Fans or other moving engine parts can
injure you badly. Keep your hands away
from moving parts once the engine is
running.
6. Check that the jumper cables do not have loose or missing insulation. If they
do, you could get a shock. The vehicles
could be damaged too.
Before you connect the cables, here are
some basic things you should know.
Positive (+) will go to positive (+) or to a
remote positive (+) terminal if the vehicle has one. Negative (–) will go to a
heavy, unpainted metal engine part or to
a remote negative (–) terminal if the
vehicle has one.
Do not connect positive (+) to negative
(–) or you will get a short that would
damage the battery and maybe other
parts too. And do not connect the
negative (–) cable to the negative (–)
terminal on the dead battery because
this can cause sparks.
7. Connect one end of the red positive (+) cable to the discharged battery
positive (+) terminal.
8. Do not let the other end touch metal. Connect it to the good battery
positive (+) terminal. Use a remote
positive (+) terminal if the vehicle
has one.
9. Connect one end of the black negative (–) cable to the good battery negative
(–) terminal. Use a remote negative (–)
terminal if the vehicle has one.
Do not let the other end touch anything
until the next step.
10. Connect the other end of the negative (–) cable to the discharged battery
negative (–) grounding point.
