2006 CADILLAC CTS V headlamp

When the exterior lamp control is in AUTO and it is dark
enough outside, the DRL will turn 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 you start your vehicle in a dark
garage, the automatic headlamp system will come on
immediately. Once you leave the garage, it will take
about 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
lever is in the full bright position. SeeInstrument
Panel Brightness on page 3-20.
If it is dark enough outside and the exterior lamp control is
off, a Headlamps Suggested message will appear on the
Driver’s Information Center (DIC) display. This message
informs the driver that turning on the exterior lamps is
recommended even though the DRL are still on.Turning the exterior lamp control to AUTO or to the
low-beam headlamp position will turn off the DRL and
cancel the Headlamps Suggested message.
If the parking lamps or the fog lamps were turned on
instead, the DRL will still turn off and the Headlamps
Suggested message will be displayed. You can turn it off
by pressing the OK button if you have the Navigation
audio system or the CLR (Clear) button if you have the
base audio system.
To drive your vehicle with the DRL off, turn the exterior
lamp control off. Then turn on the fog lamps or
parking lamps, and the DRL will turn off. The Headlamps
Suggested message will appear on the DIC display.
This will work regardless of gear position and whether or
not the parking brake is set.
As with any vehicle, you should turn on the regular
headlamp system when you need it.

Light Sensor
The light sensor for the DRL and AUTO headlamp feature
is located on top of the instrument panel. If you cover the
sensor, 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.
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):The band with/or next to this symbol
is used to turn the fog lamps on and off.
The parking lamps must be on for the fog lamps
to work.
To operate the fog lamps:
To turn the fog lamps on, turn the fog lamp band on
the lever up to the dot and release it. The band will
return to its original position.
To turn the fog lamps off, turn the for lamp band up to
the dot and release it. The band will return to its
original position, and the fog lamps will turn off. 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.

Exterior Lighting Battery Saver
If the parking lamps or headlamps have been left on,
the exterior lamps will turn off about 10 minutes after
the ignition is turned to OFF. This protects against
draining the battery in case the headlamps or parking
lamps have been left on. The battery saver does
not work if the headlamps are turned on after the
ignition is turned to OFF.
If you need to leave the lamps on for more than
10 minutes, use the exterior lamp control to turn
the lamps back on.
Instrument Panel Brightness
The lever for this
feature is located on the
overhead console.
Slide the lever toward the symbol to brighten the lights
or away from it to dim them.
If you slide the lever all the way toward the symbol past
the resistance point, the interior lamps will come on.
To turn them off, slide the lever back toward the
minimum brightness setting.

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 Remote Keyless Entry
(RKE) transmitter unlock button is pressed. If activated by
the (RKE), the lighting will remain active 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
will dim to off if the ignition key is turned to ON, or
immediately turn off if the power locks are used.
Parade Dimming
This feature prohibits dimming of the instrument panel
displays and backlighting during daylight hours when
the key is in the ignition and the headlamps are on.
This feature operates with the light sensor and is fully
automatic. When the light sensor reads darkness outside
and the parking lamps are active, the instrument
panel displays can be adjusted by sliding the instrument
panel brightness lever toward the symbol to brighten
or away from the symbol to dim the lighting.
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.
Accessory Power Outlet(s)
With accessory power outlets, you can plug in auxiliary
electrical equipment such as a cellular telephone or
CB radio.
The front accessory power outlet is located in the
ashtray on the instrument panel below the climate
control system. The outlet will have a cigarette lighter if
your vehicle has this option. Remove the cigarette
lighter to access the outlet.
The rear accessory power outlet is located on the back
of the center console.
Your vehicle may have a small cap that must be
removed to access the accessory power outlet. If it
does, when not using the outlet be sure to cover it with
the protective cap.

Fuel Gage
The fuel gage shows
approximately how much
fuel is in the fuel tank.
It works only when
the ignition is in the
ON position.
If the fuel supply gets low, the Fuel Level Low message
will appear on the Driver Information Center (DIC)
and a single chime will sound. SeeDIC Warnings and
Messages on page 3-61for more information.
Here are a few concerns some owners have had about
the fuel gage. All of these situations are normal and
do not indicate that anything is wrong with the fuel gage:
At the gas station the gas pump shuts off before
the gage reads full.
The gage may change when you turn, stop quickly
or accelerate quickly.
It takes a little more or less fuel to ll the tank than
the gage indicated. For example, the gage may
have indicated that the tank was half full, but
it actually took a little more or less than half the
tank’s capacity to ll the tank.
