134 INSTRUMENTS AND CONTROLS
If the light comes on and stays on, it
means that oil is not flowing through
the engine properly. The vehicle could
be low on oil and might have some
other system problem. See your dealer.
Low Fuel Warning Light
This light is near the fuel gauge and
comes on briefly when the ignition is
turned on as a check to show it is
working. For vehicles with a
reconfigurable cluster, this light is in
the display area and may not come on
when the ignition is turned on.
It also comes on when the fuel tank is
low on fuel. The light turns off when
fuel is added. If it does not, have the
vehicle serviced.
Auto Stop Mode (Uplevel
Cluster)
This light comes on when the engine
is in an Auto Stop.
SeeStarting the Engine 0196.
Security Light
On some vehicles the immobilizer
light should come on briefly as the
engine is started. If it does not come
on, have the vehicle serviced by your
dealer. If the system is working
normally, the indicator light turns off. For vehicles with the reconfigurable
cluster, this light may not come on
when the engine is started.
If the light stays on and the engine
does not start, there could be a
problem with the theft-deterrent
system. See
Immobilizer
Operation 044.
High-Beam On Light
This light comes on when the
high-beam headlamps are in use.
See Headlamp High/Low-Beam
Changer 0164.

Turning On and Enabling IntelliBeam
Cadillac CT6 Owner Manual (GMNA-Localizing-MidEast-10293390) - 2017 -
CRC - 6/21/16
164 LIGHTING
To enable the IntelliBeam system,
press the button on the end of the
turn signal lever when the exterior
lamp control is in the AUTO or
2
position. The blue high-beam on light
appears on the instrument cluster
when the high beams are on.
Driving with IntelliBeam
The system only activates the high
beams when driving over 40 km/h
(25 mph).
There is a sensor near the top center
of the windshield that automatically
controls the system. Keep this area of
the windshield clear of debris to allow
for best system performance.
The high-beam headlamps remain on,
under the automatic control, until one
of the following situations occurs:
.The system detects an
approaching vehicle's headlamps.
. The system detects a preceding
vehicle's taillamps.
. The outside light is bright enough
that high-beam headlamps are not
required. .
The vehicle's speed drops below
20 km/h (12 mph).
. The IntelliBeam system is disabled
by the high/low-beam changer or
the flash-to pass feature. If this
happens, press the button on the
end of the turn signal lever to
reactivate the IntelliBeam system.
The instrument cluster light will
come on to indicate the
IntelliBeam is reactivated. See
Headlamp High/Low-Beam Changer
0164 and Flash-to-Pass 0165.
The high beams may not turn off
automatically if the system cannot
detect another vehicle's lamps because
of any of the following:
. The other vehicle's lamps are
missing, damaged, obstructed from
view, or otherwise undetected.
. The other vehicle's lamps are
covered with dirt, snow, and/or
road spray.
. The other vehicle's lamps cannot
be detected due to dense exhaust,
smoke, fog, snow, road spray, mist,
or other airborne obstructions. .
The vehicle's windshield is dirty,
cracked, or obstructed by
something that blocks the view of
the light sensor.
. The vehicle is loaded such that the
front end points upward, causing
the light sensor to aim high and
not detect headlamps and
taillamps.
. Driving on winding or hilly roads.
The automatic high-beam headlamps
may need to be disabled if any of the
above conditions exist.
Exterior Lamps Off

This indicator light turns on in the
instrument cluster when the
high-beam headlamps are on.
Flash-to-Pass
To flash the high beams, pull the turn
signal lever toward you, and release.
Daytime Running
Lamps (DRL)
DRL can make it easier for others to
see the front of your vehicle during
the day.
If equipped with Light-Emitting Diode
(LED) headlamps, the dedicated DRL
will come on when all of the following
conditions are met:
.The ignition is on.
. The exterior lamp control is
in AUTO. .
The light sensor determines it is
daytime.
When the DRL are on, the taillamps
and other lamps will not be on.
The DRL turn off when the headlamps
are turned to
Oor the ignition is off.
Automatic Headlamp
System
When the exterior lamp control is set
to AUTO and it is dark enough
outside, the headlamps come on
automatically.
There is a light sensor on top of the
instrument panel. Do not cover the
sensor.
The system may also turn on the
headlamps when driving through a
parking garage or tunnel.
If the vehicle is started in a dark
garage, the automatic headlamp
system comes on immediately. If it is
light outside when the vehicle leaves
the garage, there is a slight delay
before the automatic headlamp
system changes to the DRL. During
that delay, the instrument cluster may
not be as bright as usual. Make sure
the instrument panel brightness
control is in the full bright position.
See Instrument Panel Illumination
Control 0167.
When it is bright enough outside, the
headlamps will turn off or may change
to Daytime Running Lamps (DRL).
The automatic headlamp system turns
off when the exterior lamp control is
turned to
Oor the ignition is off.

234 DRIVING AND OPERATING
Cleaning the System
If FPB does not seem to operate
properly, cleaning the outside of the
windshield in front of the rearview
mirror may correct the issue.
Night Vision System
If equipped, this system can help the
driver see and alert the driver to
pedestrians or large animals ahead of
the vehicle beyond the area lit by the
headlamps. A thermal heat image of
the view ahead is displayed when it is
dark enough outside. If a pedestrian
or large animal is detected more than
25 m (82 ft) away, an amber
pedestrian or animal icon displays and
a box appears around the pedestrian
or animal. When the system detects
that the vehicle is approaching a
pedestrian ahead much too quickly,
the box changes to red.
With the Front Pedestrian Braking
system turned on, Night Vision
provides a red Head-Up Display (HUD)
alert when the system detects that the
vehicle is approaching a pedestrian
ahead much too quickly. In addition,
an alert beeps or the Safety Alert Seat
pulses, if equipped. SeeFront
Pedestrian Braking (FPB) System 0232.
{Warning
The system does not detect all
objects or the vehicle distance from
objects. The system may not
provide a warning with enough time
to help avoid a crash.
1. Low-Beam Headlamps
2. High-Beam Headlamps
3. Night Vision System
By selecting a view on the instrument
cluster, the Night Vision image can be
displayed. See Instrument Cluster (Base
Level) 0115 orInstrument Cluster
(Uplevel) 0118. The Night Vision
system can operate only if:
. The ignition is on.
. The vehicle is in P (Park) or a
forward gear.
. It is dark enough outside.
. The headlamps are on.
