2001 CADILLAC CATERA low beam

(If Equipped)
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
qualified technician service them.

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.
Headlamps
1. With a screwdriver, unscrew the fastener on the
headlamp cover and then remove the cover to gain
access to the headlamps. Note that the inner bulb is
for the high
-beam headlamp and the outer bulb is for
the low
-beam headlamp.

Headlamp Aiming
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 flash 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 the dealer for service. However, it is
possible for you to re
-aim your headlamps by following
the procedure in the service manual for your vehicle.
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.
Front Turn Signal Lamp
1. With a screwdriver, unscrew the fastener on the
headlamp cover and then remove it to access the
turn signal lamps.

assembly counterclockwise to remove it.3. Pull the bulb out, replace it and then reassemble.

2. Depending on which outer bulb needs replacing,
open either the spare tire cover on the driver's side or
the storage compartment on the passenger's side to
