4. Lift up the wiper bladeassembly cap.
5. Pull the wiper blade assembly down far enough to release it
from the J-hooked end of the
wiper arm. Slide the assembly
away from the arm.
Allowing the wiper blade arm to
touch the windshield when no
wiper blade is installed could
damage the windshield. Any
damage that occurs would not
be covered by your warranty. Do
not allow the wiper blade arm to
touch the windshield. 6. Replace the blade with a
new one.
7. Reinstall the wiper bladeassembly by sliding it over
the wiper arm to engage the
J-hooked end. Pull up on the
assembly to lock it into place.
8. Repeat the steps for the other wiper.

4. At a wall, measure from theground upward (A) to the
recorded distance from
Step 3 and mark it.
5. Draw or tape a horizontal line (B) the width of the vehicle at the
wall where it was marked 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 aimed. This should allow only
the beam of light from the
headlamp being aimed to be
seen on the flat surface.
Driver Side Shown
7. Locate the vertical headlamp aiming screws, which are under
the hood near each headlamp
assembly. They are covered by
rubber caps.
The adjustment screw can be
turned with a 6 mm hex driver.
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.
The top edge of the cut-off
should be positioned at the
bottom edge of the horizontal
tape line.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.

others could be injured. Be sure
to read and follow the instructions
on the bulb package.
High Intensity Discharge

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.
After an HID headlamp bulb has
been replaced, the beam might be a
slightly different shade than it was
originally. This is normal.

Electrical System
Electrical System
Overload
The vehicle has fuses and circuit
breakers to protect against an
electrical system overload.
When the current electrical load is
too heavy, the circuit breaker opens
and closes, protecting the circuit
until the current load returns to
normal or the problem is fixed. This
greatly reduces the chance of circuit
overload and fire caused by
electrical problems.
Fuses and circuit breakers protect
power devices in the vehicle.
Replace a bad fuse with a new one
of the identical size and rating.
If there is a problem on the road and
a fuse needs to be replaced, the
same amperage fuse can be
borrowed. Choose some feature of
the vehicle that is not needed to use
and replace it as soon as possible.

Black plate (40,1)Cadillac CTS/CTS-V Owner Manual (Include Mex) - 2012
10-40 Vehicle Care
Headlamp Wiring
An electrical overload may cause
the lamps to go on and off, or in
some cases to remain off. Have the
headlamp wiring checked right away
if the lamps go on and off or
remain off.
Windshield Wipers
If the wiper motor overheats due to
heavy snow or ice, the windshield
wipers will stop until the motor cools
and will then restart.
Although the circuit is protected
from electrical overload, overload
due to heavy snow or ice may
cause wiper linkage damage.
Always clear ice and heavy snow
from the windshield before using the
windshield wipers.
If the overload is caused by an
electrical problem and not snow or
ice, be sure to get it fixed.
Fuses and Circuit
Breakers
The wiring circuits in the vehicle are
protected from short circuits by a
combination of fuses and circuit
breakers. This greatly reduces the
chance of damage caused by
electrical problems.
To check a fuse, look at the
silver-colored band inside the fuse.
If the band is broken or melted,
replace the fuse. Be sure to replace
a bad fuse with a new one of the
identical size and rating.
Fuses of the same amperage can
be temporarily borrowed from
another fuse location, if a fuse goes
out. Replace the fuse as soon as
you can.

breakers, and relays, seeEngine
