Steering assist function

The steering assist function operates under the following conditions.

  • Your vehicle is moving and less than about 55 km/h (34 mph).

  • White (yellow) lane lines on both sides are detected and you are driving near the centre of the lane, or your vehicle detects a vehicle ahead.

  • The direction indicator lever is not operated.

  • The headway control function is operating.

  • (Manual transmission vehicle)

    The vehicle speed is about 30 km/h (19 mph) or faster.

 

The steering assist function operates so that the vehicle remains near the centre of the driving lane, however, depending on conditions such as the road curvature, road slope and undulations, and vehicle speed, the function might not be able to keep the vehicle near the centre of the driving lane.

Setting method

  1. CANCEL switch

  2. RES switch

  3. CTS switch

 

  1. Press the CTS switch.

    The CTS standby indication (white) turns on. In addition, the CTS display indication is displayed on the multi-information display at the same time.

  2. Adjust the vehicle speed to the desired setting using the accelerator pedal and press the RES switch up (SET+) or down (SET-) to start headway control.

    The set speed is indicated on the display. At the same time, the CTS standby indication (white) changes to the CTS set indication (green).

  3. The headway control is operable when all of the conditions for it to operate are met, or the steering assist function is operable when all of the conditions for it to operate are met.

 

  • If a vehicle ahead is detected while travelling at a constant speed, the vehicle-ahead indication is displayed and headway control is performed. Additionally, when a vehicle ahead is no longer detected, the vehicle-ahead indication turns off and the system switches back to travel at constant speed.

  • The lowest possible speed which can be set on the CTS is 30 km/h (19 mph).

  • Headway control is not possible if the vehicle ahead is driving faster than your vehicle's set speed. Adjust the system to the desired vehicle speed using the accelerator pedal.

  • When the ignition is switched OFF, the system status before it was turned off is maintained. For example, if the ignition is switched OFF with the CTS operable, the CTS remains operational the next time the ignition is switched ON.

  • When the CTS switch is pressed until the system switches to the cruise standby indication (white) while the CTS is operating, the system switches to the cruise control function.

  • When the CTS is operating, the Lane-keep Assist System (LAS), Distance & Speed Alert (DSA), and Smart Brake Support (SBS) also turns on automatically.

  • When the CTS switch is pressed while the Mazda Radar Cruise Control (MRCC) or the Mazda Radar Cruise Control with Stop & Go function (MRCC with Stop & Go function) system is operating, the CTS operates. In addition, when the MRCC switch is pressed while the CTS is operating, the Mazda Radar Cruise Control (MRCC) or the Mazda Radar Cruise Control with Stop & Go function (MRCC with Stop & Go function) system operates.

Changing the set vehicle speed

(To accelerate/decelerate using the RES switch)

When the RES switch is pressed up (SET+), the vehicle accelerates and when the RES switch is pressed down (SET-), it decelerates.

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

  • Press and hold: 10 km/h (5 mph)

(To increase speed using accelerator pedal)

Depress the accelerator pedal and press the RES switch up (SET+) or down (SET-) at the desired speed. If the switch is not operated, the system returns to the set speed after you release your foot from the accelerator pedal.

 

  • The warnings and brake control do not operate while depressing the accelerator pedal.

  • (Automatic transmission vehicle)

    The vehicle speed setting can be changed by operating the RES switch during stop hold control.

Changing the distance between vehicles during headway control

The distance-between-vehicles can be set to 4 levels; Long, medium, short, and extremely short distance.

The distance-between-vehicles is set to a shorter distance by pressing the CANCEL switch down. The distance-between-vehicles is set to a longer distance by pressing the CANCEL switch up.

Distance-between-vehicles guideline
