Speed assist.
These are Predictive Speed Assist Indicator symbols. This pair are from Ford and are a large part of Advanced and Adaptive Cruise Control Systems. They are shown as curved arrows, either left or right. They go from gray to blue as speed is adjusted.
- Before continuing, is one of these truly your symbol?? If yes, read on below.
- Otherwise, you can return to our main Manufacturer Symbols pages and scan again!
In effect, cruise control “sees” a curve ahead and adjusts the vehicle’s speed accordingly, generally down. When the system detects a curve or highway exit, the vehicle starts to decelerate, and the indicator appears.
Cadillac, Audi
Cadillac and Audi use different symbols to account for essentially the same process. Their systems also have the added capability of adjusting the vehicle’s speed to account for an approaching curve in the road. The symbols shown are variations that may appear on the instrument panel indicating that the speed is being adjusted automatically, again most likely slowing down.
Land Rover
This pair from Land Rover also shows a curve in what they call Corner Speed Adaptation. The green version will be seen when the vehicle has detected a corner in the road and reduces the vehicle’s speed. The lamp will stay on until the temporary lower speed has been reached.
In yellow/amber/orange, the corner speed adaptation has a fault in this part of the adaptive cruise control system. The vehicle can be driven, but with more attention form the driver.
