Caution
If any accessories are left on or
plugged in during the jump
starting procedure, they could be
damaged. The repairs would not
be covered by the vehicle
warranty. Whenever possible, turn
off or unplug all accessories on
either vehicle when jump starting.
3. Turn off the ignition on both vehicles. Unplug unnecessary
accessories from the cigarette
lighter or the accessory power
outlet. Turn off the radio and all
lamps that are not needed.
This will avoid sparks and help
save both batteries. And it
could save the radio!
4. Open the hoods and locate the positive (+) and negative (−)
terminal locations of the other
vehicle.
{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. 5. 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
equipped. Negative (−) will go
to an unpainted metal part or to
a remote negative (−) terminal
if equipped.
Do not connect positive (+) to
negative (−) or you will get a
short that would damage the
battery and possibly other parts
too. Do not connect the
negative (−) cable to the
negative (−) terminal on the
dead battery because this can
cause sparks.
6. Connect the red positive (+) cable to the positive (+)
terminal (1) of the dead battery.
Use a remote positive (+)
terminal if equipped. Do not let
the other end touch metal.

Connect it to the positive (+)
terminal (4) of the good battery.
Use a remote positive (+)
terminal if equipped.
7. Connect the black negative (−) cable to the negative (−)
terminal (3) of the good battery.
Use a remote negative (−)
terminal if equipped.
Do not let the other end touch
anything until the next step.
The other end of the
negative (−) cable does not go
to the dead battery. It goes to
the shock tower, or to a remote
negative (−) terminal on the
vehicle with the dead battery.
8. Connect the other end of the negative (−) cable to the
negative (−) grounding point (2)
on the shock tower of the
vehicle with the dead battery.Caution
Make sure the jumper cables do
not touch moving parts in the
engine compartment and that the
cable clamps do not contact any
other metal.
9. Start the vehicle with the good battery and run the engine for a
few minutes.
10. Keep the engine speed of the booster vehicle at about 2,000
rpm, and start the engine of the
vehicle being jump started.
Caution
Do not keep the starter motor
engaged for more than
10 seconds. If the engine does
not start right away, turn the key
off and wait three to four seconds
before trying again. 11. After starting the engine,
disconnect jumper cables as
directed below.
12. If it will not start after a few tries, it probably needs service.
Caution
If the jumper cables are
connected or removed in the
wrong order, electrical shorting
may occur and damage the
vehicle. The repairs would not be
covered by the vehicle warranty.
Always connect and remove the
jumper cables in the correct order,
making sure that the cables do
not touch each other or other
metal.
Jumper Cable Removal
Reverse the sequence exactly when
removing the jumper cables.
After starting the disabled vehicle
and removing the jumper cables,
allow it to idle for several minutes.
