7. After removing the wiring harness connector from
the headlamp bulb socket, replace the bulb assembly.
Reconnect it to the wiring harness and reinstall
the headlamp bulb assembly back into the
headlamp housing.
8. After reinstalling the bulb and socket, reinstall
the rubber cover. Make sure it fully covers the
headlamp socket.
9. To replace the high
-beam bulb, turn the bulb socket
counterclockwise to unlock the socket from the lamp
housing. Follow the instructions in Step 6 through 8
to install the new bulb.Headlamp Aiming
Your vehicle has a visual optical headlamp aiming
system equipped with horizontal aim indicators. The
aim has been pre
-set 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 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 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
flat surface.
The vehicle must have all four tires on a perfectly
level surface which is level all the way to the wall or
other flat surface.
The vehicle should be placed so it is perpendicular
to the wall or other flat 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 inflated.
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.

The headlamp aiming devices are under the hood near
the headlamps.
If you believe your headlamps need horizontal
(left/right) adjustment, follow the horizontal aiming
procedure. If you believe your headlamps need only
vertical (up/down) adjustment, follow only the vertical
aiming procedure.
Adjustment screws can be turned with an E8 Torx
socket or T15 Torx screwdriver.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.

Headlamp Vertical Aiming
1. Find the aim dot on the lens of the lamps.
2. Measure the distance from the ground to the aim dot
on each lamp. Record this distance.3. At the wall or other flat surface, measure from the
floor to the recorded distance and draw a horizontal
line the width of the vehicle.

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 the beam cut
-off of
the headlamp being aimed to be seen on the flat 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 (C) until the
headlamp beam is aimed to the horizontal tape line.

6-44 Front Turn Signal Lamps
1. The turn signal lamps are located on the outboard
side of the headlamps. To access, remove the
headlamp, (see Steps 1, 2 and 3 under ªHeadlampsº).
2. Press the bulb socket tab and turn the bulb socket
counterclockwise to unlock the socket from the
lamp housing.
3. To remove the old bulb, grasp the socket firmly and
pull the bulb out. Install the new bulb and reverse the
steps to reinstall the lamp housing.
Rear Turn Signal Lamps and Taillamps
1. Open the trunk to gain access to the lamp housing.
2. Remove the rear
compartment sill plate
by removing the upper
convenience net
retainers, located at
each end, as shown.
3. Move the spare tire cover out of the way.
4. Pull the trunk trim away to access the wing nuts.

5. Remove the three wing nuts that fasten the taillamp
to the body.
6. Gently remove the taillamp from the body. The
taillamp is on the bottom of the housing and the rear
turn signal lamp is on the upper part of the housing.7. Press the bulb socket tab and turn the socket
counterclockwise to remove it. To remove the bulb,
grasp the socket firmly and pull the bulb out.
Once you have replaced the burned
-out bulb, reverse the
steps to reassemble the lamp assembly.

Windshield Wiper
Blade Replacement
Windshield wiper blades should be inspected at least
twice a year for wear or cracking. See ªWiper Blade
Checkº in your Maintenance Schedule booklet
under Part B ªOwner Checks and Servicesº for
more information.
It's a good idea to clean or replace the wiper blade
assembly on a regular basis or when worn. For proper
windshield wiper blade length and type, see ªNormal
Maintenance Replacement Partsº in the Index.
To replace the wiper blade assembly:
1. Lift the wiper up from the windshield and set into
the vertically
-locked position.2. Press the tab that holds the wiper blade to the arm.
3. Slide the blade down and off the arm.
4. Slide in the new blade and snap into place.

Tires
Your new vehicle comes with high-quality tires made by
a leading tire manufacturer. If you ever have questions
about your tire warranty and where to obtain service,
see your Cadillac Warranty booklet for details.
CAUTION:
Poorly maintained and improperly used tires
are dangerous.
Overloading your tires can cause
overheating as a result of too much friction.
You could have an air
-out and a serious
accident. See ªLoading Your Vehicleº in
the Index.
CAUTION: (Continued)
CAUTION: (Continued)
Underinflated tires pose the same danger
as overloaded tires. The resulting accident
could cause serious injury. Check all tires
frequently to maintain the recommended
pressure. Tire pressure should be checked
when your tires are cold.
Overinflated tires are more likely to be
cut, punctured or broken by a sudden
impact
-- such as when you hit a pothole.
Keep tires at the recommended pressure.
Worn, old tires can cause accidents. If your
tread is badly worn, or if your tires have
been damaged, replace them.
See ªInflation -- Tire Pressureº in this section
for inflation pressure adjustment for higher
speed driving.

6-48 Inflation -- Tire Pressure
The Tire-Loading Information label, which is located
on the rear edge of the driver's door, shows the correct
inflation pressures for your tires when they're cold.
ªColdº means your vehicle has been sitting for at least
three hours or driven no more than 1 mile (1.6 km).
If you'll be driving at high speeds (e.g., speeds of
100 mph (160 km/h) or higher), where it is legal, set
the cold inflation pressure to the maximum inflation
pressure shown on the tire sidewall, or to 38 psi
(265 kPa), whichever is lower. See the example below.
When you end this high
-speed driving, return to the
cold inflation pressure shown on the Tire
-Loading
Information label.
Example:
You'll find maximum load and inflation pressure
molded on the tire's sidewall, in small letters, near the
rim flange. It will read something like this: Maximum
load 690 kg (1521 lbs.) @ 300 kPa (44 psi) Max. Press.
For this example, you would set the inflation pressure
for high
-speed driving at 38 psi (265 kPa).
NOTICE:
Don't let anyone tell you that underinflation or
overinflation is all right. It's not. If your tires
don't have enough air (underinflation), you can
get the following:
Too much flexing
Too much heat
Tire overloading
Bad wear
Bad handling
Bad fuel economy.
If your tires have too much air (overinflation),
you can get the following:
Unusual wear
Bad handling
Rough ride
Needless damage from road hazards.
