2008 CADILLAC CTS headlamp

Rainsense™ windshield wipers operate in a delay
mode, as well as a continuous low or high speed as
needed. Move the wiper lever up to the delay position
and turn the band to one of ve settings.
The level one or lowest setting is at the bottom of the
band. This setting lets more rain or snow collect on the
windshield between wipes. Turn the delay band forward
to a higher setting to let less rain or snow collect on
the windshield between wipes.
The top position is the highest setting. A single wipe
occurs each time the delay band is turned to a higher
setting to indicate that the Rainsense
®level has
been increased.
Notice:Going through an automatic car wash with
the wipers on can damage them. Turn the wipers
off when going through an automatic car wash.The mist and wash cycles operate as normal and
are not affected by the Rainsense™ function.
The Rainsense™ system can be overridden at any
time by manually changing the wiper control to low or
high speed. The system will default to normal time delay
operation if the Rainsensor detects something that
would affect Rainsense™ operation.
When Rainsense™ is active, the headlamps turn
on automatically. If it is dark, they remain on.
See “Wiper-Activated Headlamps” underWiper
Activated Headlamps on page 3-17for more
information.
Notice:Do not place stickers or other items on
the exterior glass surface directly in front of
the moisture sensor. Doing this could cause the
moisture sensor to malfunction.

Headlamps
The exterior lamp control is located towards the end of
the turn signal/multifunction lever.
O(Exterior Lamp Control):Turn the band with this
symbol on it to operate the exterior lamps.
The exterior lamp control has four positions:
O(Off):This position turns off all lamps, except the
Daytime Running Lamps (DRL).
AUTO (Automatic):This position puts the headlamps
in automatic mode. AUTO mode turns the exterior
lamps on and off depending upon how much light is
available outside of the vehicle.

Wiper Activated Headlamps
This feature activates the headlamps and parking lamps
after the windshield wipers have been in use for about
six seconds. For this feature to work, the exterior lamp
control must be in AUTO.
The wiper-activated headlamps immediately turn off,
when the ignition is turned to LOCK/OFF or the
windshield wiper control is turned off.
Headlamps 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 (DRL)
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 either the reduced intensity
low-beam headlamps or dedicated DRL’s come on
when the following conditions are met:
It is still daylight and the ignition is in ON/RUN or
START.
The exterior lamp control is in off or AUTO and the
headlamps are off.
The automatic transmission is not in PARK (P).
When DRL’s are on, only the reduced intensity
low-beam headlamps or dedicated DRL’s will be on.
No other exterior lamps will be on. The instrument panel
cluster will not be lit up either.When the exterior lamp control is in AUTO and it is dark
enough outside, the DRL turns off and the low-beam
headlamps will turn on. When it is bright enough outside,
the low-beam headlamps will go off, and the DRL will
turn back on. If the vehicle is started in a dark garage,
the automatic headlamp system comes on immediately.
Once the vehicle leaves the garage, it takes about
one minute for the automatic headlamp system
to change to DRL if it is light outside. During that delay,
the instrument panel cluster may not be as bright as
usual. Make sure the instrument panel brightness lever
is in the full bright position. SeeInstrument Panel
Brightness on page 3-20.
Turning the exterior lamp control to off or to the
low-beam headlamp position will turn off the DRL.
If the parking lamps or the fog lamps were turned on
instead, the DRL will still turn off.
This will work regardless of gear position and whether
or not the parking brake is set.

Light Sensor
The light sensor for the
DRL and AUTO headlamp
feature is located on
top of the instrument panel.
If the sensor is covered, it will prevent it from sensing
light, and the exterior lamps or the Headlamps
Suggested message will appear on the DIC whenever
the ignition is on.
Adaptive Forward Lighting System
The Adaptive Forward Lighting System (AFL) swivels
the headlamps horizontally to provide greater road
illumination while turning. AFL will operate when
the vehicle speed is greater than 2 mph (3 km/h).
AFL will not operate when the transmission is in
REVERSE (R). AFL is not immediately operable afterstarting the vehicle; driving a short distance is required
to calibrate the AFL. To enable AFL, set the exterior
lamp switch on the multifunction lever to the AUTO
position. Moving the switch out of the AUTO position will
deactivate the system. SeeHeadlamps on page 3-17.
Fog Lamps
Use the fog lamps for better vision in foggy or misty
conditions.
The fog lamp control is located on the turn
signal/multifunction lever.
-(Fog Lamps):Turn the fog lamp band on the lever
up to
-and release it, to turn the fog lamps on or
off. The band will return to its original position.
The parking lamps must be on for the fog lamps to work.
If the high-beam headlamps are turned on, the fog
lamps will also turn off. They will turn back on again
when you switch back to low-beam headlamps.
Some localities have laws that require the headlamps to
be on along with the fog lamps.
3-19

Exterior Lighting Battery Saver
The exterior lamps turn off about 10 minutes after the
ignition is turned to LOCK/OFF, if the parking lamps
or headlamps have been left on. This protects against
draining the battery. The battery saver does not
work if the headlamps are turned on after the ignition
is turned to LOCK/OFF.
To keep the lamps on for more than 10 minutes, turn
the lamps back on with the exterior lamp control.
Instrument Panel Brightness
The knob with this symbol
is located on the instrument
panel to the left of the
steering column.
Turn the knob clockwise or counterclockwise to brighten
or dim the lights.
Turn the knob completely clockwise to turn on the
interior lamps.
Entry Lighting
The entry lighting system turns on the reading and
dome lamps and the backlighting to the exterior lamp
control, when a door is opened or if the transmitter
unlock button is pressed. If activated by the transmitter,
the lighting stays on for about 25 seconds. The entry
lighting system uses the light sensor on the instrument
panel; so it must be dark outside in order for the
lamps to turn on. The lamps turn off about 25 seconds
after the last door is closed. They dim then turn
off if the ignition key is turned to ON/RUN. They
immediately turn off if the power locks are used.
Parade Dimming
This feature does not let the instrument panel backlight
dim during daylight hours while the key is in the
ignition and the headlamps are on. Parade dimming
automatically works with the light sensor, located on top
of the dashboard. If it is dark enough outside and the
parking lamps are on, the backlight on the instrument
panel can be adjusted by turning the instrument panel
brightness knob clockwise or counterclockwise to
brighten or dim the lighting. SeeInstrument Panel
Brightness on page 3-20.

Reading Lamps
The reading lamps are located on the overhead console.
These lamps come on automatically when any door is
opened.
For manual operation, press the button next to each
lamp to turn it on or off.
If the reading lamps are left on, they automatically shut
off 10 minutes after the ignition has been turned off.
Electric Power Management
The vehicle has Electric Power Management (EPM) that
estimates the battery’s temperature and state of charge.
It then adjusts the voltage for best performance and
extended life of the battery.
When the battery’s state of charge is low, the voltage
is raised slightly to quickly put the charge back in.
When the state of charge is high, the voltage is lowered
slightly to prevent overcharging. If the vehicle has a
voltmeter gage or a voltage display on the Driver
Information Center (DIC), you may see the voltage
move up or down. This is normal. If there is a problem,
an alert will be displayed.The battery can be discharged at idle if the electrical
loads are very high. This is true for all vehicles.
This is because the generator (alternator) may not be
spinning fast enough at idle to produce all the power that
is needed for very high electrical loads.
A high electrical load occurs when several of the
following loads are on: headlamps, high beams, fog
lamps, rear window defogger, climate control fan at
high speed, heated seats, engine cooling fans, trailer
loads, and loads plugged into accessory power outlets.
EPM works to prevent excessive discharge of the
battery. It does this by balancing the generator’s output
and the vehicle’s electrical needs. It can increase
engine idle speed to generate more power, whenever
needed. It can temporarily reduce the power demands of
some accessories.
Normally, these actions occur in steps or levels, without
being noticeable. In rare cases at the highest levels
of corrective action, this action may be noticeable to
the driver. If so, a Driver Information Center (DIC)
message might be displayed, such as Battery Saver
Active or Service Battery Charging System. If this
message is displayed, it is recommended that the
driver reduce the electrical loads as much as possible.
SeeDIC Warnings and Messages on page 3-56.
