CTS operation conditions

The CTS speed can be set when all of the following conditions are met.

  • The brake pedal is not depressed.

  • The vehicle speed is about 0 km/h (0 mph) to 145 km/h (90 mph).

  • The Mazda Radar Cruise Control is available.

Setting the CTS

  1. Press the CTS switch to turn the system on.

    When the system is on, the CTS standby indication (white) is displayed on the screen.

  2. Accelerate to the desired speed.

  3. Set the vehicle speed by pressing the RES switch up (SET+) or down (SET-).

    Constant speed driving starts when the vehicle speed is set. In addition, the set speed is displayed on the screen, and the CTS standby indication (white) changes to the CTS set indication (green).

If a vehicle ahead is detected while traveling at a constant speed, the system switches to headway control. The vehicle ahead indication is displayed on the screen while in headway control.

  1. Set speed

  2. Vehicle ahead indication

 

  • If there is a structure on the road or an obstruction at a low height off the ground in front of the vehicle, the system may recognize it as a vehicle ahead.

  • Acceleration and deceleration by accelerator pedal operation takes priority while traveling at a constant speed or in headway control. When the accelerator pedal is released, the vehicle returns to driving at a constant speed or headway control at the set speed.

  • The Forward Sensing Camera (FSC) may not be able to detect target objects correctly, and the CTS may not operate normally.

    Refer to Forward Sensing Camera (FSC) (Search).

  • If a vehicle ahead is traveling at an extremely low speed, the system may not detect it correctly.

  • While driving using the CTS, intended engine braking is not applied even if the selector lever is operated.

  • The brake lights turn on while the brakes are operating by the CTS control.

Steering assist within vehicle lane lines

Steering assist along the trajectory of the vehicle ahead

 

  • The steering assist function assists the steering wheel operation so that the vehicle remains near the center of the driving lane, however, the function might not be able to keep the vehicle near the center of the driving lane when any of the following conditions is met.

    • The vehicle speed is high.

    • The vehicle is making a sharp turn.

If the vehicle ahead stops during headway control, your vehicle in headway control also stops. While the vehicle is stopped, the CTS indicator light in the Instrument cluster turns on.

When the vehicle ahead accelerates from a stop and one of the following operations is performed, your vehicle starts driving.

  • Press the RES switch.

  • Depress the accelerator pedal.

If you do not start driving the vehicle after the vehicle ahead has resumed driving, the system urges the driver to resume driving.

 

  • If the vehicle ahead resumes driving within 3 seconds after the vehicle was stopped by the system, your vehicle also resumes driving automatically.

  • If the vehicle is stopped by the system continuously for 10 minutes or longer, the parking brake is applied automatically. At this time, the CTS is canceled.

  • Even if the CTS is canceled while the vehicle is stopped, the vehicle is held in its stopped position.

    Refer to AUTOHOLD (Search).

  • If the CTS is canceled while the vehicle is stopped and there is no vehicle ahead, you cannot resume driving the vehicle using the RES switch. Depress the accelerator pedal and start driving the vehicle.

  • If the i-stop operation conditions are met while the vehicle is stopped, the i-stop function operates without depressing the brake pedal. The engine restarts automatically when you start driving the vehicle.

    Refer to i-stop (Search).
