Auto high beams

Auto high beams  - Headlamp control - Lights - Lincoln MKS Owners Manual - Lincoln MKS

During nighttime driving, the automatic high beam system automatically turns on your high beams if it is dark enough and no other traffic is present. When it detects an approaching vehicles headlights or a preceding vehicles tail lamps, the system turns off the high beams (low beams remain on) before they distract other drivers.

If the vehicle is equipped with automatic high beams, the high beam switch will operate differently depending on the status of the automatic high beam system. Each of the possible operating scenarios are detailed below:

Scenario 1:

Conditions - The automatic high beam system is set to ON in the message center. The headlamp switch is in automatic high beam system has turned the high beams on. (auto lamps). The automatic high beam system has turned the high beams on.

Operation - The high beam switch will not perform any function.

Scenario 2:

Conditions - The automatic high beam system is set to ON in the message center. The headlamp switch is in automatic high beam system has not turned the high beams on. (auto lamps). The automatic high beam system has not turned the high beams on.

Operation - The high beam switch can be used to turn the high beams on. They will then remain on until the switch has been returned to the neutral position and the auto high beam system has turned the high beams off.

Scenario 3:

Conditions - The automatic high beam system is set to ON in the message center. The headlamp switch is in (parking lamps), (off), or (on). (parking lamps), or (on).

Operation - The high beam switch can be used to turn the high beams on and off.

Scenario 4:

Conditions - The automatic high beam system is set to OFF in the message center. The headlamp switch is in lamps),  (off), (auto lamps), (parking lamps), or (off), (on). (parking lamps), or Operation - The high beam switch can be used to turn the high beams (on).

Operation - The high beam switch can be used to turn the high beams on and off.

Enabling/disabling auto high beams

Enabling/disabling and/or checking the status of the automatic high beam system can be performed using the message center. See Message center in the Instrument Cluster chapter.

Activating high beams

If there is no traffic in front of the vehicle, the high beams will come on automatically and the display in the instrument panel if light will display in the instrument panel if the following are true:

The headlamp control is in auto lamp  Fog lamps are turned off. mode.
Fog lamps are turned off.
The ambient light level is low enough that high beams are needed.
Vehicle speed must be greater than 32 mph (51 km/h).
Severe weather is not detected.

Deactivating high beams

The automatic high beams will deactivate if any of the following events occur:

An approaching vehicles headlights or a preceding vehicles tail lamps are detected.
The headlamp control is moved out of the autolamps position.
The vehicle speed falls below 27 mph (43 km/h).
The ambient light level is high enough that high beams are not needed.
Severe rain, snow or fog is detected.
The camera is blocked.

Note: Activating the multi-function lever will put the headlamps in manual high beam mode (constant or flash-to-pass) until the lever is returned to the neutral position. To manually override the auto high beam and go to low beam, the headlamp control must be taken out of the fog on freeways, or severe fog (autolamp) position. For severe fog on freeways, or severe fog in low traffic situations, use of fog lamps is recommended.

Setting auto high beam sensitivity

The automatic high beam system has two sensitivity settings. The default setting is near. If you would like the high beams to turn off when traffic is further away, the sensitivity setting can be changed to far. The procedure is as follows:

Preconditions:

Vehicle is at a stop.
Ignition is in the on position.
The headlamp control is in the position. position.
High-beams are off.

Programming Sequence:

1. Turn the headlamp control from (on) to  (autolamp) three (on) to times within two seconds, ending in (autolamp) three times within two seconds, ending in (on). (on).
2. Cycle flash-to-pass three times using the multi-function lever.
3. The high beams will flash momentarily to confirm that the sensitivity setting has been changed.

Note: The programming sequence will end if either of the following occur:

The vehicle speed is not zero.
The battery voltage is out of normal range.

Troubleshooting

If the automatic high beam camera becomes blocked, the high beams may 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 systems performance. However, in cold or inclement weather conditions, the automatic high beam systems availability may be decreased. In such conditions, the manual override may be used to turn the high beams on or off.

For significant blockages (e.g. bird dropping, bug splatter, snow, or ice), the automatic high beam system uses a blocked sensor computer program. If a blockage is detected and no changes are observed, the system will go into low beam mode until the blockage is cleared. If blockages are repeatedly detected, the system will stay in low beam mode for the remainder of the ignition cycle unless the system is able to begin detecting other vehicles again.

If it appears that automatic control of the high beams is not functioning properly, check the windshield in front of the camera for blockage.
