Follow Mode
A set speed is selected and this speed is maintained until a slower vehicle is encountered in the lane ahead. When the vehicle ahead comes within the effective range of the Adaptive Speed Control Module (ASCM) radar, the system identifies it as a target vehicle. When the distance between the 2 vehicles closes to the set time gap, the ASCM reduces engine speed. The ASCM applies the brakes to maintain the set time gap when it is necessary.
To indicate that the system is in 'Follow Mode':
- The 'Follow Mode' warning indicator illuminates in the Instrument Cluster (IC).
- The current time gap setting is displayed in the message center.

Automatic braking is limited to approximately 30% of full pressure (0.3G deceleration). Automatic braking is intended to provide a smooth, gradual deceleration in 'Follow Mode' conditions.
'Follow Mode' is effectively a closed loop system. If several vehicles are ahead, the closest vehicle is chosen as the target to follow.
The system exits 'Follow Mode' and extinguishes the 'Follow Mode' warning indicator:
- If the target vehicle moves out of the Adaptive Speed Control Module (ASCM) radar range.
- If either vehicle changes lane.
The adaptive speed control system then increases vehicle speed back to the original set speed.
