When the speed limit is intentionally ex-
ceeded by stepping on the accelerator
pedal all the way down, there is no signal.
▷
Each time the rocker switch is pressed
past the resistance point, the desired speed
changes by a maximum of 5 mph/10 km/h.
Displays in the instrument cluster

ally exceeded such as when driving downhill,
the vehicle is not actively braked.
Display in the speedometer
