2009 LINCOLN MKS sensor

Troubleshooting
If the automatic high beam camera becomes blocked, the high beams will
not come on automatically. They will only activate when they are
manually turned on with the multi-function lever.
Typical road dust, dirt and water spots will not affect the automatic high
beam system’s performance.
For significant blockages (e.g. bird dropping, bug splatter, snow, or ice),
the automatic high beam system uses a blocked sensor computer
program. If it detects a blockage, it will be monitored for two minutes. If
no changes are observed, the system will go into low beam mode until
the blockage is cleared.
If it appears that automatic control of the high beams is not functioning,
check the windshield in front of the camera for blockage.
Flash to pass
Pull toward you to activate and
release to deactivate.
Daytime running lamps (DRL) (if equipped)
To activate:
•the ignition must be in the on position,
•the headlamp control must be in the off, autolamps or parking lamp
position and
•the transmission must be out of the P (Park) position.
WARNING:Always remember to turn on your headlamps at
dusk or during inclement weather. The Daytime Running Lamp
(DRL) system does not activate the tail lamps and generally may not
provide adequate lighting during these conditions. Failure to activate
your headlamps under these conditions may result in a collision.

day/night mirrors will change from the normal (high reflective) state to
the non-glare (darkened) state when bright lights (glare) reach the
interior mirror. When the interior mirror detects bright light from behind
the vehicle, the interior rear view mirror and the driver’s side exterior
mirror will automatically adjust (darken) to minimize glare.
With microphone
The mirrors will automatically return to the normal state whenever the
vehicle is placed in R (Reverse) to ensure a bright clear view when
backing up.
Do not block the sensors on the front and back of the interior
rear view mirror since this may impair proper mirror
performance.
Do not clean the housing or glass of any mirror with harsh
abrasives, fuel or other petroleum-based cleaning products.
EXTERIOR MIRRORS
Power side view mirrors
WARNING:Do not adjust the mirror while the vehicle is in
motion.
To adjust your mirrors:
1. Rotate the control clockwise to
adjust the right mirror and rotate
the control counterclockwise to
adjust the left mirror.
2. Move the control in the direction
you wish to tilt the mirror.
3. Return to the center position to lock mirrors in place.
Automatic dimming feature
The driver’s side view mirror has an auto-dimming function. For more
information, refer toAutomatic dimming interior rear view mirrorin
this chapter.

Note:If the ACC system predicts that its maximum braking level will not
be sufficient, then an audible warning will sound while the ACC
continues to brake. This is accompanied by DRIVER INTERVENE
displayed in the message center. The driver should takeimmediate
action.
Note:The brakes may emit a sound when they are being modulated by
the adaptive cruise control system.
WARNING:Adaptive cruise control only warns of vehicles
detected by the radar sensor. In some cases there may be no
warning or the warning may be delayed. The driver should always
apply the brakes when necessary. Failing to do so may result in a
collision, serious injury or death.
Setting the gap distance
The distance between your vehicle
and the vehicle in front of you can
be decreased or increased by
pressing<--->control. GAP <--->
will be displayed in the message
center. Three gap distance settings
are available:

Turning off cruise control
To turn off the cruise control:
•Press the OFF control.
Note:When you turn off the cruise
control or the ignition, your cruise
control set speed memory is erased.
Detection issues
The radar sensor has a limited field of vision. In some situations it may
not detect vehicles at all or detect a vehicle later than expected.
Detection issues can occur:
•When driving on a different line than the vehicle in front.
•With vehicles that edge into your lane. (these vehicles can only be
detected once they have moved fully into your lane.)

•There may be issues with the detection of vehicles in front when
driving into and coming out of a bend or curve in the road.
In these cases ACC may brake late or unexpectedly. The driver should
stay alert and intervene when necessary.
ACC Not Available
Several conditions exist which can cause ACC to deactivate or prevent
ACC from activating when requested. These conditions include:
•The sensor is blocked, refer toBlocked sensorin this section.
•Brake temperature is high, refer toHilly condition usagein this
section.
•A failure has occurred in the ACC system or related system.
Blocked sensor
If the message CRUISE RADAR
BLOCKED is displayed, the radar
signals from the sensor have been
obstructed, a vehicle ahead cannot
be detected and the ACC will not
function. The following table lists
possible causes and actions for this
message being displayed.

In the event of a multiple warning situation, the message center will
cycle the display to show all warnings by displaying each one for several
seconds.
The message center will display the last selected feature if there are no
more warning messages. This allows you to use the full functionality of
the message center after you acknowledge the warning by pressing the
RESET control and clearing the warning message.
Warning messages that have been reset are divided into three categories:
•They will not disappear until a condition is changed.
•They will reappear on the display ten minutes from the reset.
•They will not reappear until an ignition off-on cycle has been
completed.
This acts as a reminder that these warning conditions still exist within
the vehicle.
