2018 Acura RDX Owners Manual - Adaptive Cruise

1. Press the MAIN button.
    
2. Accelerate to the desired speed above 25 mph (40 km/h). Press the DECEL/SET button and take your foot off the pedal to set the speed.

Press the RES/ACCEL button to increase speed or the DECEL/SET button to decrease speed.

Each time you press the button, the vehicle speed is increased or decreased by about 1 mph (1 km/h). If you keep the button pressed, the vehicle speed increases or decreases by 5 mph (5 km/h) until you release it.

Press the Interval button to change the following interval. Each time you press the button, the interval setting cycles through short, middle, long, and extra long.

Press and hold the Distance button. Cruise Mode appears in the multi-information display. Press and hold the button again to switch back to ACC.

If a vehicle is detected ahead of you when ACC is turned on and your vehicle is traveling at or below the set speed, the system maintains, accelerates, or decelerates your vehicle's set speed to keep your vehicle's set following interval from the vehicle ahead.

If a vehicle detected ahead of you slows down abruptly, or if another vehicle cuts in front of you, a beep sounds and BRAKE appears on the multi-information display to alert you.

You can press CANCEL or MAIN, or press the brake pedal. The ACC indicator goes off.

Certain conditions may cause ACC to cancel automatically. When this happens, the amber ACC indicator appears on the multi-information display (see "Malfunction Indicators" section).

After cruise control has been canceled, you can still resume the prior set speed by pressing RES/ACCEL when your vehicle speed is over 25 mph (40 km/h).
