headlamp CADILLAC DTS 2007 1.G Owner's Guide

Bulb Replacement
It is recommended that all bulbs be replaced by
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
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.
Windshield Wiper Blade
Replacement
Windshield wiper blades should be inspected for
wear or cracking. SeeScheduled Maintenance
on page 465for more information on wiper blade
inspection.
Replacement blades come in different types and
are removed in different ways. Here’s how to
remove the wiper blade:
1. Turn the engine off.
2. Lift the windshield wiper arm and blade away
from the windshield.
3. Pull the clip up from the blade connecting point,
and pull the blade assembly down toward the
windshield to remove it from the wiper arm.

{CAUTION:
Using the wrong replacement wheels,
wheel bolts, or wheel nuts on your vehicle
can be dangerous. It could affect the
braking and handling of your vehicle,
make your tires lose air and make you
lose control. You could have a collision in
which you or others could be injured.
Always use the correct wheel, wheel bolts,
and wheel nuts for replacement.
Notice:The wrong wheel can also cause
problems with bearing life, brake cooling,
speedometer or odometer calibration,
headlamp aim, bumper height, vehicle ground
clearance, and tire or tire chain clearance
to the body and chassis.If your vehicle is a professional model, the wheels
have a unique offset and bolt hole diameter.
Each of the wheels on the professional vehicle
have eight wheels nuts. The wheels on the
non-professional vehicle have ve wheel nuts. See
Changing a Flat Tire on page 428for more
information.
Used Replacement Wheels
{CAUTION:
Putting a used wheel on your vehicle is
dangerous. You cannot know how it has
been used or how far it has been driven. It
could fail suddenly and cause a crash. If
you have to replace a wheel, use a new
GM original equipment wheel.

Electrical System
Add-On Electrical Equipment
Notice:Do not add anything electrical to your
vehicle unless you check with your dealer
rst. Some electrical equipment can damage
your vehicle and the damage would not
be covered by your warranty. Some add-on
electrical equipment can keep other
components from working as they should.
Add-on equipment can drain your vehicle’s battery,
even if your vehicle is not operating.
Your vehicle has an airbag system. Before
attempting to add anything electrical to your
vehicle, seeServicing Your Airbag-Equipped
Vehicle on page 86.
Headlamp Wiring
The headlamp wiring system has four individual
fuses. An electrical overload will cause the
lamps to go on and off, or in some cases to remain
off. If this happens, have the headlamp wiring
checked right away.
Windshield Wiper Fuses
The windshield wiper motor is protected by an
internal circuit breaker. If the wiper motor overheats
due to heavy snow, the wipers will stop until the
motor cools and will then restart.
A fuse powers the wiper motor. If the fuse blows,
there is an electrical problem. Be sure to have
it xed.
