2006 CHEVROLET AVALANCHE Owners Manual

{CAUTION:
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
ashlight if you need more light.
Be sure the battery has enough water. You do
not need to add water to the battery installed
in your new vehicle. But if a battery has ller
caps, be sure the right amount of uid is there.
If it is low, add water to take care of that rst.
If you do not, explosive gas could be present.
Battery uid contains acid that can burn you.
Do not get it on you. If you accidentally get it
in your eyes or on your skin, ush the place
with water and get medical help immediately.
{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 (−)oryou
will get a short that would damage the battery
and maybe other parts too.
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. Do not 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.
5-49

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.
Your vehicle’s remote negative (−) terminal is
marked GND.
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.
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 awhile.
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.

5-50

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 remote positive (+) terminal cover, if
equipped, to its original position.Rear Axle
When to Check 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.
All axle assemblies are lled by volume of uid during
production. They are not lled to reach a certain
level. When checking the uid level on any axle,
variations in the readings can be caused by factory ll
differences between the minimum and the maximum
uid volume. Also, if a vehicle has just been driven
before checking the uid level, it may appear lower than
normal because uid has traveled out along the axle
tubes and has not drained back to the sump area.
Therefore, a reading taken ve minutes after the vehicle
has been driven will appear to have a lower uid
level than a vehicle that has been stationary for an
hour or two. Remember that the rear axle assembly
must be supported to get a true reading.
5-51

How to Check Lubricant
To get an accurate reading, the vehicle should be on a
level surface.
The proper level for the 1500 Series is from 5/8 inch
to 1 5/8 inch (15 mm to 40 mm) below the bottom of
the ller plug hole, located on the rear axle. The
proper level for the 2500 Series is from 0 to 1/2 inch
(0 to 13 mm) below the bottom of the ller plug
hole. Add only enough uid to reach the proper level.
What to Use
Refer to the Maintenance Schedule to determine what
kind of lubricant to use. SeeRecommended Fluids
and Lubricants on page 6-12.
Four-Wheel Drive
Transfer Case
It is not necessary to regularly check transfer case 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 change the lubricant. SeeScheduled
Maintenance on page 6-4.
1500 Series shown, 2500 Series similar
5-52

How to Check Lubricant
1. Remove the ller plug.
2. Add new uid until the level is below the bottom of
the ller plug hole, located on the transfer case. To
get an accurate reading, the vehicle should be
on a level surface.
Refer to the Maintenance Schedule to determine
what kind of lubricant to use. SeeRecommended
Fluids and Lubricants on page 6-12.
3. Reinstall the ller plug. Use care not to overtighten
the ller plug.
Front Axle
When to Check and Change Lubricant
It is not necessary to regularly check front 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.
How to Check Lubricant
To get an accurate reading, the vehicle should be on a
level surface.
5-53

If the level is below the bottom of the ller plug hole,
located on the front axle, you may need to add
some lubricant:
When the differential is cold, add enough lubricant
to raise the level from 1/2 inch (12 mm) to about
5/8 inch (18 mm) below the ller plug hole for
the 1500 series, and from 1/4 inch (6 mm) to about
3/8 inch (10 mm) below the ller plug hole for
2500 series.
When the differential is at operating temperature
(warm), 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. SeeRecommended Fluids
and Lubricants on page 6-12.
Bulb Replacement
For the proper type of replacement bulbs, see
Replacement Bulbs on page 5-63.
