2003 CADILLAC SEVILLE low beam

Turn Signal/Multifunction Lever
The lever located on the left side of the steering column
includes the following:
·Turn and Lane Change Signals
·Headlamp High/Low-Beam Changer
·Flash-To-Pass
For information on the exterior lamps, see
Exterior
Lamps on page 3-16.
Turn and Lane-Change Signals
To signal a turn, move the lever on the left side of the
steering wheel all the way up or down. The lever returns
automatically when the turn is complete.
An arrow located on the
instrument panel cluster
will ¯ash in the direction of
the turn or lane change.
Raise or lower the lever until the arrow starts to ¯ash to
signal a lane change. Hold it there until the lane change is
complete. The lever returns when it is released.
If the turn signal is left on, a warning chime will sound
and the Driver Information Center (DIC) will display
TURN SIGNAL ON after driving about a mile to remind
you to turn it off.
Arrows that ¯ash rapidly when signaling for a turn or
lane change may be caused by a burned-out signal bulb.
Other drivers won't see the turn signal.
Replace burned-out bulbs to help avoid possible
accidents. Check the fuse and for burned-out bulbs if
the arrow fails to work when signaling a turn. See
Fuses
and Circuit Breakers on page 5-93.

Headlamp High/Low-Beam Changer
When the low-beam headlamps are on, push the turn
signal lever away from you to change the headlamps to
high beam.
This light on the instrument
panel cluster will be on,
indicating high-beam
usage.
Pull the turn signal lever toward you to return to
low-beam headlamps.
Flash-To-Pass
This feature lets you use the high-beam headlamps to
signal the driver in front of you that you want to pass.
Pull the turn signal lever toward you brie¯y to
¯ash-to-pass. When you do, the following will occur:
·If the headlamps are either off or in the Daytime
Running Lamps (DRL) mode, the high-beam
headlamps will turn on. They'll stay on as long as
you hold the lever there. Release the lever to
turn them off.
·If the headlamps are on low beam, they will remain
active and the high beam will also illuminate until
you release the lever.
Windshield Wipers
You can control the windshield wipers by moving the
lever with the wiper symbol on it. This lever is located on
the right side of your steering column. For information
on wiper-activated headlamp operation, refer to
Exterior
Lamps on page 3-16.
The following is a list of the available settings:
LO or HI:Move the lever up to LO for steady wiping at
a slow speed. Move the lever higher to HI for steady
wiping at a high speed.

Wiper-Activated Headlamps
This feature activates the headlamps and parking lamps
after the windshield wipers have been in use for
about six seconds. To operate, the Twilight Sentinel
ž
feature must be turned on.
When the exterior lamp control is in the off or parking
lamp position and the wiper control is on INT, LO or HI,
the HEADLAMPS SUGGESTED message will appear
on the Driver Information Center (DIC).
When the ignition is turned to OFF, the wiper-activated
headlamps will immediately turn off. The wiper-activated
headlamps will also turn off if the Twilight Sentinel
ž
or the windshield wipers are turned off.
Lamps On Reminder
A warning chime will sound if the exterior lamp control
is left on in either the headlamp or parking lamp position
and the driver's door is opened with the ignition off.
Daytime Running Lamps
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the
day. DRL can be helpful in many different driving
conditions, but they can be especially helpful in the short
periods after dawn and before sunset. Fully functional
daytime running lamps are required on all vehicles
®rst sold in Canada.
The DRL system will make the high-beam headlamps
come on at reduced brightness when the following
conditions are met:
·It is still daylight and the ignition is on,
·the exterior lamp control is in the off position and
·the transaxle is not in PARK (P).
When DRL are on, only your high-beam headlamps (at
reduced brightness) will be on. No other exterior
lamps such as the parking lamps, taillamps, etc. will be
on when the DRL are being used. Your instrument
panel won't be lit up either.
When the Twilight Sentinel
žlever is on and it's dark
enough outside, the high-beam headlamps (at reduced
intensity) will turn off and normal low-beam headlamp
operation will occur.
3-17

When the Twilight Sentinelžlever is on and it's bright
enough outside, the regular lamps will go off, and
the high-beam headlamps at reduced brightness will
take over. If you start your vehicle in a dark garage, the
automatic headlamp system will come on immediately.
Once you leave the garage, it will take approximately
one minute for the automatic headlamp system to
change to DRL if it is light outside. During that delay,
your instrument panel cluster may not be as bright
as usual. Make sure your instrument panel brightness
knob is in the full bright position. See ªInstrument Panel
Brightnessº under
Interior Lamps on page 3-21.
If it's dark enough outside and the Twilight Sentinel
ž
lever is off, a HEADLAMPS SUGGESTED message will
display on the Driver's Information Center (DIC). This
message informs the driver that turning on the exterior
lamps is recommended even though the DRL are
still illuminated. Turning on the Twilight Sentinel
žor the
headlamps will deactivate the DRL and remove the
HEADLAMPS SUGGESTED message. If the parking
lamps or the fog lamps were turned on instead, the DRL
will still deactivate and the HEADLAMPS SUGGESTED
message will continue to be displayed.
To idle your vehicle with the DRL off at night, turn off
the Twilight Sentinel
žand shift the transaxle into
PARK (P). Placing your vehicle in PARK (P) disables
the DRL. The DRL will stay off until you shift out
of PARK (P).To drive your vehicle with the DRL off, turn off the
Twilight Sentinel
žand manually turn on the parking
lamps or fog lamps.
As with any vehicle, you should turn on the regular
headlamp system when you need it.
Fog Lamps
Use the fog lamps for better vision in foggy or misty
conditions.
-(Fog Lamps):Press the button with this symbol on
it, located next to the exterior lamp control, to turn the
fog lamps on.
When the ignition is on and you press the fog lamp
button, a small indicator light in the fog lamp button, the
LIGHTS ON and fog lamp indicator lights on the
instrument panel cluster will come on to indicate that the
fog and the parking lamps are on.
Press the fog lamp button again to turn off the
fog lamps.
If you turn on the high-beam headlamps, the fog lamps
will turn off. They'll turn back on again when you
switch to low-beam headlamps.
When the Twilight Sentinel
žis on and the fog lamps are
turned on, the fog lamps, headlamps and parking
lamps will remain on.
The ignition must be on for the fog lamps to operate.

Battery Load Management
The battery load management feature is designed to
monitor the vehicle's electrical load and determine when
the battery is in a heavy discharge condition. During
times of high electrical loading, the engine may idle at a
higher revolutions per minute (rpm) setting than
normal to make sure the battery charges. High electrical
loads may occur when several of the following are
on: headlamps, high beams, fog lamps, rear window
defogger, the climate control fan at high speeds, heated
seats and engine cooling fans.
If the battery continues to discharge, even with the
engine idling at a higher rpm setting, some electrical
loads will automatically be reduced. When this occurs,
the rear window defogger may take slightly longer
to clear the glass, the heated seats may not get as warm
as they usually do and the fan may cut back to a
lower speed. For more battery saving information, see
ªBattery Saver Active Messageº under
DIC Warnings
and Messages on page 3-56.
Inadvertent Power Battery Saver
This feature is designed to protect your vehicle's battery
against drainage from the interior lamps, trunk lamp,
glove box lamp, cigarette lighters or the garage
door opener. When the ignition is turned off, the power
to these features will automatically turn off after
10 minutes (three minutes if a new car has 15 miles
(24 km) or less). Power will be restored for an additional
10 minutes if any door is opened, the trunk is opened
or the courtesy lamp switch is turned on.

You can be temporarily blinded by approaching
headlamps. It can take a second or two, or even several
seconds, for your eyes to readjust to the dark. When
you are faced with severe glare (as from a driver
who doesn't lower the high beams, or a vehicle with
misaimed headlamps), slow down a little. Avoid staring
directly into the approaching headlamps.
Keep your windshield and all the glass on your vehicle
clean Ð inside and out. Glare at night is made much
worse by dirt on the glass. Even the inside of the glass
can build up a ®lm caused by dust. Dirty glass makes
lights dazzle and ¯ash more than clean glass would,
making the pupils of your eyes contract repeatedly.
Remember that your headlamps light up far less of a
roadway when you are in a turn or curve. Keep
your eyes moving; that way, it's easier to pick out dimly
lighted objects. Just as your headlamps should be
checked regularly for proper aim, so should your eyes
be examined regularly. Some drivers suffer from
night blindness Ð the inability to see in dim light Ð and
aren't even aware of it.Driving in Rain and on Wet Roads
Rain and wet roads can mean driving trouble. On a wet
road, you can't stop, accelerate or turn as well
because your tire-to-road traction isn't as good as on
dry roads. And, if your tires don't have much tread left,
you'll get even less traction. It's always wise to go
slower and be cautious if rain starts to fall while you are
driving. The surface may get wet suddenly when your
re¯exes are tuned for driving on dry pavement.

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.
5-51

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.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
ž
socket or T15 Torx screwdriver.
