6. Connect the red
positive (+) cable to the
positive (+) terminal of
the dead battery. Use
a remote positive (+)
terminal if the vehicle
has one.
7. Don’t let the other end
touch metal. Connect
it to the positive (+)
terminal of the good
battery. Use a remote
positive (+) terminal if
the vehicle has one.8. Now connect the black
negative (−) cable to
the negative (−)
terminal of the good
battery. Use a remote
negative (−) terminal
if the vehicle has one.
Don’t let the other end touch anything until the next
step. The other end of the negative (−) cabledoesn’t
go to the dead battery. It goes to a heavy, unpainted
metal engine part, or to a remote negative (−)
terminal on the vehicle with the dead battery.
9. Connect the other end of the negative (−) cable at
least 18 inches (45 cm) away from the dead battery,
but not near engine parts that move. The electrical
connection is just as good there, and the chance of
sparks getting back to the battery is much less.

wrong order, electrical shorting may occur and
damage the vehicle. The repairs would not be
covered by your warranty. Remove the jumper
cables in the correct order, making sure that the
cables do not touch each other or other metal.

Rear Axle
When to Check and Change Lubricant
It is not necessary to regularly check rear axle uid
unless you suspect there is a leak or you hear an
unusual noise. A uid loss could indicate a problem.
Have it inspected and repaired.
Refer to the Maintenance Schedule to determine
how often to check the lubricant and when to change
it. SeePart A: Scheduled Maintenance Services
on page 6-4.
How to Check Lubricant
To get an accurate reading, the vehicle should be on
a level surface.
If the level is below the bottom of the ller plug hole,
you’ll need to add some lubricant. Add enough lubricant
to raise the level to the bottom of the ller plug hole.
What to Use
Refer to the Maintenance Schedule to determine what
kind of lubricant to use. SeePart D: Recommended
Fluids and Lubricants on page 6-33.
