CADILLAC ESCALADE EXT 2003 2.G Owners Manual

All-Wheel Drive
Lubricant checks in this section also apply to these
vehicles. However, there are two additional systems that
need lubrication.
Transfer Case
When to Check Lubricant
Refer to the Maintenance Schedule to determine how
often to check the lubricant. SeePart C: Periodic
MaintenanceInspections on page 6-15.
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.
Use care not to overtighten the plug.
What to Use
Refer to the Maintenance Schedule to determine what
kind of lubricant to use. SeePart D: Recommended
Fluids and Lubricants on page 6-17. (A) Filler Plug (B) Drain Plug

Rear Axle
When to Check Lubricant
Refer to the Maintenance Schedule to determine how
often to check the lubricant. 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.The proper level is from 5/8 inch to 1 5/8 inch
(15 mm to 40 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. SeePart D: Recommended
Fluids and Lubricants on page 6-17.

Front Axle
When to Check and Change Lubricant
Refer to the Maintenance Schedule to determine how
often to check the lubricant and when to change it. See
Part 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 may need to add some lubricant.
When the differential is cold, add enough lubricant to
raise the level to 1/2 inch (12 mm) below the ®ller
plug hole.
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. SeePart D: Recommended
Fluids and Lubricants on page 6-17.

Headlamp Aiming
Your vehicle has a visual optical headlamp aiming system
equipped with horizontal aim indicators. The aim has
been preset at the factory and should need no further
adjustment. This is true even though your horizontal aim
indicators may not fall exactly on the ª0º (zero) marks on
their scales.
If your vehicle is damaged in an accident, the headlamp
aim may be affected. Aim adjustment to the low beam
may be necessary if it is difficult to see lane markers
(for horizontal aim), or if oncoming drivers ¯ash
their high beams at you (for vertical aim).
If you believe your headlamps need to be re-aimed, we
recommend that you take your vehicle to your dealer
for service. However, it is possible for you to re-aim your
headlamps as described in the following procedure.
Notice:To make sure your headlamps are aimed
properly, read all the instructions before beginning.
Failure to follow these instructions could cause
damage to headlamp parts.
The vehicle should be properly prepared as follows:
·The vehicle should be placed so the headlamps are
25 ft. (7.6 m) from a light colored wall or other ¯at
surface.
·The vehicle must have all four tires on a perfectly
level surface which is level all the way to the wall
or other ¯at surface.
·The vehicle should be placed so it is perpendicular
to the wall or other ¯at surface.
·The vehicle should not have any snow, ice or mud
attached to it.
·The vehicle should be fully assembled and all other
work stopped while headlamp aiming is being done.
·The vehicle should be normally loaded with a
full tank of fuel and one person or 160 lbs. (75 kg)
on the driver's seat.
·Tires should be properly in¯ated.
·Start the vehicle and rock it to level the suspension.
Headlamp aiming is done with the vehicle low beam
lamps. The high beam lamps will be correctly aimed if
the low beam lamps are aimed properly.
5-53

The headlamp aiming devices are under the hood near
the headlamps.
If you believe your headlamps need horizontal (H)
(left/right) adjustment, follow the horizontal aiming
procedure. If you believe your headlamps need only
vertical (V) (up/down) adjustment, follow only the vertical
aiming procedure.
Adjustment screws can be turned with an E8 Torx
ž
socket or T15 Torxžscrewdriver.
Headlamp Horizontal Aiming
Turn the horizontal aiming screw (A) until the
indicator (B) is lined up with zero.
Once the horizontal aim is adjusted, then adjust the
vertical aim.
5-54

Headlamp Vertical Aiming
Notice:Horizontal aiming must be performed
before making any adjustments to the vertical aim.
Adjusting the vertical aim ®rst will result in an
incorrect headlamp aim.
1. Find the aim dot on the lens of the low beam
lamps.
2. Measure the distance from the ground to the aim
dot on each low beam lamp. Record this distance.3. At the wall or other ¯at surface, measure from the
ground upward the recorded distance from Step 2
and draw or tape a horizontal line the width of
the vehicle.
5-55

4. Turn on the low-beam headlamps and place a
piece of cardboard or equivalent in front of the
headlamp not being aimed. This should allow only
the beam of light from the headlamp being
aimed to be seen on the ¯at surface.
Notice:Do not cover a headlamp to improve beam
cut-off when aiming. Covering a headlamp may
cause excessive heat build-up which may cause
damage to the headlamp.5. Turn the vertical aiming screw (V) until the
headlamp beam is aimed to the horizontal tape line.
The top edge of the cut-off should be positioned
at the bottom edge of the horizontal tape line.
6. Repeat steps 4 and 5 for the opposite headlamp.

Bulb Replacement
SeeReplacement Bulbs on page 5-64for the proper
type of bulbs to use.
For any bulb changing procedure not listed in this
section, contact your dealer.
High Intensity Discharge (HID)
Lighting
{CAUTION:
The low beam high intensity discharge lighting
system operates at a very high voltage. If you
try to service any of the system components,
you could be seriously injured. Have your
dealer or a quali®ed technician service them.
After your vehicle's HID headlamp bulb has been
replaced, you may notice that the beam is a slightly
different shade than it was originally. This is normal.
Halogen Bulbs
{CAUTION:
Halogen bulbs have pressurized gas inside and
can burst if you drop or scratch the bulb. You or
others could be injured. Be sure to read and
follow the instructions on the bulb package.

4. Pull the top left or right corner of the grill out so the
clips release. This will give you the needed
clearance for removing the headlamp assembly.5. Remove the horizontal pin from the headlamp
assembly by lifting the end of the pin upward
until it unsnaps and then pulling it toward the center
of the vehicle.
