Forward and reverse sensing systems

Forward and reverse sensing systems  - Driving - Lincoln MKS Owners Manual - Lincoln MKS

The forward and reverse sensing system will warn the driver of obstacles within a certain range of the front and rear bumpers.

The front sensors will be active when the gearshift is in any position other than P (Park) or N (Neutral) and the vehicle speed is below 8 mph (13 km/h). The rear sensors will only be active when the gearshift is in R (Reverse).

The front sensors cover an area up

The front sensors cover an area up to 27.6 inches (70 cm) from the front of the vehicle and about 69 in. (1523 cm) to the side of the front end of the vehicle. See the illustration for approximate sensor area coverage.

The reverse sensing portion of the

The reverse sensing portion of the system detects obstacles up to 6 ft (2 m) from the rear bumper with a decreased coverage area at the outer corners of the bumper, (refer to the illustration for approximate zone coverage areas). As you move closer to the obstacle, the rate of the tone increases. When the obstacle is less than 10 inches (25.0 cm) away, the tone will sound continuously. If the system detects a stationary or receding object further than 10 inches (25.0 cm) from the side of the vehicle, the tone will sound for only three seconds. Once the system detects an object approaching, the tone will sound again.

While receiving a rear detection warning, the radio volume will be

While receiving a rear detection warning, the radio volume will be reduced to a predetermined level. After the warning goes away, the radio will return to the previous value.

WARNING: To help avoid personal injury, please read and understand the limitations of the forward and reverse sensing system as contained in this section. Sensing is only an aid for some (generally large and fixed) objects when moving in reverse on a flat surface at parking speeds. Traffic control systems, inclement weather, air brakes, and external motors and fans may also affect the function of the sensing system; this may include reduced performance or a false activation.

WARNING: To help avoid personal injury, always use caution when in R (Reverse) and when using the sensing system.

WARNING: This system is not designed to prevent contact with small or moving objects. The system is designed to provide a warning to assist the driver in detecting large stationary objects to avoid damaging the vehicle. The system may not detect smaller objects, particularly those close to the ground.

WARNING: Certain add-on devices such as large trailer hitches, bike or surfboard racks and any device that may block the normal detection zone of the forward and reverse sensing system may create false beeps.

The system will sound a tone to warn the driver of obstacles near either bumper in the following manner:

The front sensors will sound a high pitched tone which will appear to come from the dashboard
The rear sensors will sound a lower pitched tone which will appear to come from the rear interior of the vehicle
The sensing system will report the obstacle which is closest to the front or rear of the vehicle. For example, if an obstacle is 12 inches (30 cm) from the front of the vehicle and, at the same time, an obstacle is only six inches (15 cm) from the rear of the vehicle, the lower pitched tone will sound.

The reverse sensing portion of the system will assist the driver in detecting certain objects while:

the vehicle is in R (Reverse) and moving toward a stationary object at a speed of 3 mph (5 km/h) or less.
the vehicle is in R (Reverse) but not moving, and a moving object is approaching the front or rear of the vehicle at a speed of 3 mph (5 km/h) or less.
the vehicle is in R (Reverse) and moving at a speed of less than 3 mph (5 km/h) and a moving object is approaching the rear of the vehicle at a speed of less than 3 mph (5 km/h).

The system is automatically enabled when the gearshift lever is placed in D (Drive) or R (Reverse) and the ignition is on. A control in the message center allows the driver to disable the forward (if equipped) and/or reverse system. Refer to Message center in the Instrument Cluster chapter for more information. The message center will indicate a failure in the forward or reverse system and will not allow the driver to switch the faulted system on.

Note: If the system cannot be turned off, refer to MyKey in the Locks and Security chapter for more information.

The system defaults to enabled every time the ignition is switched on.

Press the control to disable or enable the system

free from snow, ice and large accumulations of dirt (do not clean the sensors with sharp objects). If the sensors are covered, it will affect the accuracy of the sensing system.

If your vehicle sustains damage to the front or rear bumper/fascia, leaving it misaligned or bent, the sensing zone may be altered causing inaccurate measurement of obstacles or false alarms.
