Notes:
• The service alignment process measures the path of stationary targets such as streetlamps,
railings, road signs parked vehicles etc., and uses this data to correct for radar misalignment.
• Alignment will complete more quickly if more suitable targets are seen.
• The speed must be above 30mph (48kph).
• Choose a road with plenty of obstacles.
• Choose an inside or outside lane.
• Following vehicles too closely will obscure the stationary targets from the radar, a time gap of
2 seconds is recommended.
• A straighter road will produce a quicker and better result, although the process will still operate
on a curved road.
• The time the module takes to align will vary, depending on the route, speed, number of targets,
and individual module.
• Whentheashing‘followicon’lampextinguishes,thesystemiscorrectlyaligned.
• To be fully functional the following process needs to be carried out:
• Stop the vehicle at the next available opportunity.
• Turntheignitiono󰀨andwait15seconds.
• Start the engine, once 15 seconds have elapsed.
• The adaptive speed system should now be fully functional and the user can now set a desired
speed, allowing the adaptive speed control to operate as normal.
