When the vehicle speed is at or below the posted speed or advisory speed, the speedometer remains green. The HUD speedometer will turn yellow when the vehicle speed exceeds the speed alert limit. When the vehicle speed is at or below the alert limit, the speedometer remains green.PEDAL APPLIED ACC OVERRIDE When the PEDAL APPLIED ACC OVERRIDE message displays, the accelerator pedal is being pressed and the Adaptive Cruise Control is overridden and cannot automatically apply the brakes.

To clean the HUD, spray household glass cleaner on a soft, clean cloth. Wipe the HUD lens gently, then dry. Notice: When cleaning, be careful not to scratch the HUD or camera lenses. Do not sprayglass cleaner directly on the HUD lens because the cleaner could leak inside the unitand cause damage. . 4-41
