How to Use the Cruising & Traffic Support (CTS)

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 Hill Descent Control is not operating.

  • 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.

  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.

The steering assist function operates if all of the following conditions are met while traveling at a constant speed or in headway control.

  • When driving near the center of the lane and the white (yellow) lane lines on both sides are detected clearly, or a vehicle ahead is detected clearly in front of your vehicle and at less than about 56 km/h (35 mph).

  • The steering wheel is not turned sharply.

  • The turn signal lever is not operated.

When the steering assist function operates, the steering assist operation display changes from white to green.

  • 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.

    • The vehicle is driven on a road with steep or up and down (wavy) slopes.

    • The vehicle is driven on a road with a large lateral gradient.

  • If you take your hands off the steering wheel, a warning (amber) is indicated on the instrument cluster and the active driving display. Then, if you continue to leave your hands off the steering wheel, a warning (red) is indicated on the instrument cluster and the active driving display and a warning sound is activated.

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).

Changing the set vehicle speed

Changing the set vehicle speed using the RES switch

Press the RES switch up (SET+) or down (SET-) to the desired speed.

  • Press and release immediately: 1 km/h (1 mph)

  • Press and hold: 10 km/h (5 mph)

Changing the set vehicle speed using the accelerator pedal

Depress the accelerator pedal until the vehicle speed reaches the desired speed, then press the RES switch up (SET+) or down (SET-).

Reading the set vehicle speed from the speed limit sign using the RES switch

Press the RES switch when the speed limit sign set indication turns on.

 

  • The function which recognizes speed limit signs has limitations. Always check the set vehicle speed that was read.

  • Set the speedometer display unit to the same unit as the speed limit sign. Differing units will capture speeds not intended by the driver.

  • The Speed Limit Assist operates only when the navigation system's SD card is inserted.

  • The Speed Limit Assist uses the Traffic Sign Recognition system (TSR).

    Refer to Traffic Sign Recognition System (TSR) (Search).

  • The Speed Limit Assist cannot read speeds of less than 30 km/h (19 mph).

  • Set vehicle speeds read from speed limit signs can be adjusted.

    Refer to the Settings section in the Mazda Connect Owner's Manual.

  • The Speed Limit Assist can be turned off.

    Refer to the Settings section in the Mazda Connect Owner's Manual.
