Dodge Charger: AUXILIARY DRIVING SYSTEMS / Forward Collision Warning (FCW) With Mitigation Operation

FCW with Mitigation provides the driver with audible warnings, visual warnings (within the instrument cluster display), and may apply haptic warning in the form of a a brake jerk, to warn the driver when it detects a potential frontal collision. The warnings and limited braking are intended to provide the driver with enough time to react, avoid or mitigate the potential collision.

NOTE:

FCW monitors the information from the forward looking sensors, as well as the Electronic Stability Control (ESC) system, to calculate the probability of a forward collision. When the system determines that a forward collision is probable, the driver will be provided with audible and visual warnings and may provide a brake jerk warning. If the driver does not take action based upon these progressive warnings, then the system will provide a limited level of active braking to help slow the vehicle and miti- gate the potential forward collision. If the driver reacts to the warnings by braking and the system determines that the driver intends to avoid the collision by braking but has not applied sufficient brake force, the system will compensate and provide additional brake force as required. If a Forward Collision Warning with Mitigation event begins at a speed below 20 mph (32 km/h), the system may provide the maximum or partial braking to mitigate the potential forward collision. If the Forward Colli- sion Warning with Mitigation event stops the vehicle completely, the system will hold the vehicle at standstill for two seconds and then release the brakes.

When the system determines a collision with the vehicle in front of you is no longer probable, the warning message will be deactivated.

NOTE:

• The minimum speed for FCW activation is 1 mph (2 km/h).
• The FCW alerts may be triggered on objects other than vehicles such as guard rails or sign posts based on the course prediction. This is expected and is a part of normal FCW activation and functionality.
• It is unsafe to test the FCW system. To prevent such misuse of the system, after four Active Braking events within an ignition cycle, the Active Braking portion of FCW will be deactivated until the next ignition cycle.
• The FCW system is intended for on-road use only. If the vehicle is taken off-road, the FCW system should be deactivated to prevent unnecessary warnings to the surroundings.

WARNING!

Forward Collision Warning (FCW) is not intended to avoid a collision on its own, nor can FCW detect every type of potential collision. The driver has the responsibility to avoid a collision by controlling the vehicle via braking and steering. Failure to follow this warning could lead to serious injury or death.

Turning FCW On Or Off

The FCW button is located on the Uconnect display in the control settings. Forward Collision can be checked or unchecked.

When FCW is selected off, there will be an "FCW OFF" icon that appears in the instrument cluster display.

Changing the FCW status to off prevents the system from warning you of a possible collision with the vehicle in front of you.

NOTE:

The FCW system’s default state is on. The FCW system state is kept in memory from one igni- tion cycle to the next. If the system is turned Off, it will remain off when the vehicle is restarted.

Changing FCW And Active Braking Status

The FCW Sensitivity and Active Braking settings are programmable through the Uconnect system.

The default status of FCW is the “Far” setting and the Active Braking is set to “on”; this allows the system to warn you of a possible collision with the vehicle in front of you when you are farther away and it applies limited braking. This gives you the most reaction time to avoid a possible collision.

Changing the FCW status to the “Near” setting, allows the system to warn you of a possible collision with the vehicle in front of you when you are much closer. This setting provides less reaction time than the “Far” setting, which allows for a more dynamic driving experience.

NOTE:

• The system will retain the last setting selected by the driver after ignition shut down.
• FCW may not react to irrelevant objects such as overhead objects, ground reflections, objects not in the path of the vehicle, stationary objects that are far away, oncoming traffic, or leading vehicles with the same or higher rate of speed.
• FCW disables in the same manner as ACC, and will display a screen indicating that the feature is unavailable when it has been disabled.

FCW Limited Warning

If the instrument cluster display reads “ACC/ FCW Limited Functionality” or “ACC/FCW Limited Functionality Clean Front Windshield” momentarily, there may be a condition that limits FCW functionality. Although the vehicle is still drivable under normal conditions, the active braking may not be fully available. Once the condition that limited the system performance is no longer present, the system will return to its full performance state. If the problem persists, see an authorized dealer.

Service FCW Warning

If the system turns off, and the instrument cluster display reads:

• ACC/FCW Unavailable Service Required
• Cruise/FCW Unavailable Service Required

This indicates there is an internal system fault. Although the vehicle is still drivable under normal conditions, have the system checked by an authorized dealer.
