2008 CADILLAC ESCALADE ESV Owners Manual

All-Wheel Drive Transfer Case If your vehicle is equipped with All-Wheel Drive, be sure
to perform the lubricant checks described in this section.
There are two additional systems that need lubrication.
When to Check Lubricant Refer to the Maintenance Schedule to determine
how often to check the lubricant. See Scheduled
Maintenance 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,
located on the transfer case, 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. See Recommended Fluids
and Lubricants on page 6-13 .

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. How to Check Lubricant
To get an accurate reading, the vehicle should be on a
level surface.
For Two-Wheel-Drive vehicles, the proper level is
from 0.6 inch to 1.6 inches (15 mm to 40 mm)
below the bottom of the ller plug hole, located on
the rear axle. Add only enough uid to reach
the proper level.
For All-Wheel-Drive vehicles, the proper level is
from 0.04 inch to 0.75 inch (1.0 mm to 19.0 mm)
below the bottom of the ller plug hole, located on
the rear axle. 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. See Recommended Fluids
and Lubricants on page 6-13 .
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. A: Fill Plug
B: Drain Plug
When the differential is cold, add enough lubricant to
raise the level from 0 (0 mm) to 1/8 inch (3.2 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. See Recommended Fluids
and Lubricants on page 6-13 .1500 Series

Headlamp Aiming The vehicle has a visual optical headlamp aiming
system. The aim of the headlamps have been preset at
the factory and should need no further adjustment.
However, if the vehicle is damaged in a crash, the aim
of the headlamps may be affected and adjustment
may be necessary.
If oncoming vehicles ash their high beams at you,
this may mean the vertical aim of your headlamps
needs to be adjusted.
It is recommended that the vehicle is taken to your
dealer/retailer for service if the headlamps need
to be adjusted. It is possible however, to re-aim the
headlamps as described. The vehicle should:
Be placed so the headlamps are 25 ft. (7.6 m) from
a light colored wall or other at surface.
Have all four tires on a level surface which is level
all the way to the wall or other at surface.
Be placed so it is perpendicular to the wall or other
at surface.
Not have any snow, ice, or mud on it.
Be fully assembled and all other work stopped while
headlamp aiming is being performed.
Be normally loaded with a full tank of fuel and one
person or 160 lbs (75 kg) sitting on the driver seat.
Have the tires properly inated.
Have the spare tire is in its proper location in the
vehicle.

Headlamp aiming is done with the vehicle’s low-beam
headlamps. The high-beam headlamps will be correctly
aimed if the low-beam headlamps are aimed properly.
To adjust the vertical aim:
1. Open the hood. See Hood Release on page 5-11
for more information.
2. Locate the center of
the projector lens
of the low-beam
headlamp.
3. Record the distance from the ground to the center
of the projector lens of the low-beam headlamp. 4. At a wall, measure from the ground upward (A) to
the recorded distance from Step 3 and mark it.
5. Draw or tape a horizontal line (B) on the wall the
width of the vehicle at the height of the mark
in Step 4.
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.
6. Turn on the low-beam headlamps and place a
piece of cardboard or equivalent in front of the
headlamp not being adjusted. This allows only the
beam of light from the headlamp being adjusted
to be seen on the at surface.
5-49

7. Locate the vertical headlamp aiming screws, which
are under the hood near each headlamp assembly.
The adjustment screw can be turned with a
E8 Torx ®
socket.
8. Turn the vertical aiming screw until the headlamp
beam is aimed to the horizontal tape line. Turn it
clockwise or counterclockwise to raise or lower the
angle of the beam. 9. Make sure that the light from the headlamp is
positioned at the bottom edge of the horizontal tape
line. The lamp on the left (A) shows the correct
headlamp aim. The lamp on the right (B) shows the
incorrect headlamp aim.
10. Repeat Steps 7 through 9 for the opposite headlamp.

Bulb Replacement For the proper type of replacement bulbs, see
Replacement Bulbs on page 5-53 .
For any bulb changing procedure not listed in this
section, contact your dealer/retailer.
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/retailer or a qualied technician
service them.
Your vehicle has HID headlamps. 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. Back-Up Lamps To replace this bulb:
1. Open the liftgate.
See Power Liftgate
on page 2-14 for more
information.

2. Remove the two screws
from the taillamp
assembly.
3. Pull the taillamp assembly rearward until you
disengage the inner pins on the taillamp assembly
from the vehicle. 4. Press the release tab, if the bulb socket has one,
and turn the socket counterclockwise to remove it
from the taillamp assembly.
5. Pull the old bulb straight out from the socket.
6. Press a new bulb into the socket, insert the socket
into the taillamp assembly and turn the socket
clockwise into the taillamp assembly until it clicks.
7. Reinstall the taillamp assembly. When reinstalling,
make sure to line up the pins on the taillamp
assembly with the vehicle. If you do not line up the
pins correctly, you will not be able install the
taillamp assembly properly.
If you need to replace the taillamp, stoplamp, or
turn signal, you will need to see your dealer/retailer
for service.
