CHEVROLET IMPALA 2007 9.G Owners Manual

{CAUTION:
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 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.6. Connect the red positive (+) cable to the
positive (+) terminal location of the vehicle
with the dead battery. Use a remote
positive (+) terminal if the vehicle has one.
7. Do not let the other end touch metal. Connect
it to the positive (+) terminal location of the
vehicle with the good battery. Use a remote
positive (+) terminal if the vehicle has one.
8. Now connect the black negative (−) cable
to the negative (−) terminal location of the
vehicle with the good battery. Use a remote
negative (−) terminal if the vehicle has one.
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 a heavy, unpainted metal engine part or to a
remote negative (−) terminal on the vehicle with
the dead battery.
341

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.
10. Now start the vehicle with the good battery
and run the engine for a while.
11. Try to start the vehicle that had the dead
battery. If it will not start after a few tries,
it probably needs service.
Notice: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 your
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.A. Heavy, Unpainted Metal Engine Part or
Remote Negative (−) Terminal

Jumper Cable Removal
342

To disconnect the jumper cables from both
vehicles, do the following:
1. Disconnect the black negative (−) cable from
the vehicle that had the dead battery.
2. Disconnect the black negative (−) cable from
the vehicle with the good battery.
3. Disconnect the red positive (+) cable from the
vehicle with the good battery.
4. Disconnect the red positive (+) cable from the
other vehicle.
5. Return the fuse block cover to its original
position.Headlamp Aiming
Headlamp aim has been preset at the factory and
should need no further adjustment.
However, if your vehicle is damaged in an accident,
the headlamp aim may be affected. Aim adjustment
to the low-beam headlamps may be necessary if it
is difficult to see the lane markers (for horizontal
aim), or if oncoming drivers ash their high-beam
headlamps at you (for vertical aim).
If you believe your headlamps need to be
re-aimed, it is recommend that you take the vehicle
to your dealer for service.

from the windshield.
2. While holding the wiper arm, pull the clip up
from the blade connecting point, and pull the
blade assembly down toward the windshield
to remove it from the wiper arm.
3. Install the new wiper blade onto the wiper arm
and snap the clip down into place.

To remove and replace the wiper blade element
do the following:
1. The wiper blade element has two notches at
one end which are engaged by the bottom
claw set of the wiper blade. At the notched
end of the wiper blade, pull the wiper
blade element from the wiper blade assembly.
2. To replace the element, start at the heel end
of the wiper blade, which is the end nearest to
the base of the wiper arm, and slide the
wiper blade element, notched end last, into
the wiper blade claw sets.
3. To engage the last claw into the notched end
of the wiper blade element, squeeze the wiper
blade element at the notched area, and
push the wiper blade element so the claw ts
into the notch.
4. Be sure the two wiper blade element notches
are engaged by the last claw set, and that all
the other claws are properly engaged in the
slots of the wiper blade element on both sides.A. Correct Installation
