Forward Alert Warning Indicator

WARNING: This page is about a different car, the 2015 Jaguar XF, 2014 Jaguar XF, and 2013 Jaguar XF. However, it is still accessible from the selected car via links, so may be relevant.

The forward alert system uses the adaptive speed control system components. Forward alert is turned on and off independently of adaptive speed control, via the instrument cluster menu. Forward alert will notify the driver by means of a chime, and warning indicator in the instrument cluster and indication in the message center, when a target vehicle comes into range. The system will NOT use throttle or brake intervention to slow the vehicle.

When forward alert is selected on or off, the instrument cluster sends the forward alert information to the adaptive speed control module on the CAN (controller area network) bus. When a forward alert sensitivity adjustment is made using the time gap increase/decrease on the right steering wheel switchpack. The switches are connected via fly leads to the clockspring and pass a signal a LIN (local interconnect network) bus signal, via the clockspring to the CJB. The CJB routes the selected sensitivity adjustment signals to the adaptive speed control radar sensor on the high speed CAN bus.

NOTE: This system is intended as a driver aid and should be used as such. The system is NOT a collision warning or avoidance device.

The system sensitivity can be adjusted in the same manner as the Adaptive Speed Control, via the right steering wheel switchpack. Each adjustment is accompanied by a message in the instrument cluster.
