2003 CADILLAC ESCALADE EXT service indicator

Notice:
·Using the wrong ¯uid can badly damage brake
system parts. For example, just a few drops of
mineral-based oil, such as engine oil, in your
brake system can damage brake system
parts so badly that they'll have to be replaced.
Don't let someone put in the wrong kind of ¯uid.
·If you spill brake ¯uid on your vehicle's painted
surfaces, the paint ®nish can be damaged.
Be careful not to spill brake ¯uid on your
vehicle. If you do, wash it off immediately.
See ªAppearance Careº in the Index.
Brake Wear
Your vehicle has four-wheel disc brakes.
Disc brake pads have built-in wear indicators that make
a high-pitched warning sound when the brake pads
are worn and new pads are needed. The sound
may come and go or be heard all the time your vehicle
is moving (except when you are pushing on the
brake pedal ®rmly).
{CAUTION:
The brake wear warning sound means that soon
your brakes won't work well. That could lead to
an accident. When you hear the brake wear
warning sound, have your vehicle serviced.
Notice:Continuing to drive with worn-out brake
pads could result in costly brake repair.
Some driving conditions or climates may cause a brake
squeal when the brakes are ®rst applied or lightly
applied. This does not mean something is wrong with
your brakes.

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.

If the system is ever reset accidentally, you must
change your oil at 3,000 miles (5 000 km) since your
last oil change. Remember to reset the oil life system
whenever the oil is changed. See
Engine Oil on
page 5-14for information on resetting the system.
An Emission Control Service.
Lubricate chassis components with each engine oil
and ®lter change.
Lubricate the front suspension, ball joints, steering
linkage, transmission shift linkage and parking brake
cable guides. Ball joints should not be lubricated unless
their temperature is 10ÉF (-12ÉC) or higher, or they
could be damaged.
See the mileage intervals following for additional
services that may be performed with an engine oil
change and chassis lubrication. After the services are
performed, record the date, odometer reading and
who performed the service on the maintenance record
pages in Part E of this schedule.
