During travel at constant speed

During travel under headway control

 

  • 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.

  • If you are driving the vehicle at a speed faster than the set speed, headway control on the vehicle ahead is not possible Adjust the system to the desired vehicle speed using the accelerator pedal.

How to Set the Distance Between Vehicles During Headway Control

The distance between vehicles is set to a shorter distance each time the switch is pressed. The distance between vehicles is set to a longer distance by pressing the switch. The distance-between-vehicles can be set to 4 levels; Long, medium, short, and extremely short distance.

Distance-between-vehicles guideline

(at 80 km/h (50 mph) vehicle speed)

Indication on display

Long (about 50 m (164 ft))

Medium (about 40 m (131 ft))

Short (about 30 m (98 ft))

Extremely short (about 25 m (82 ft))

 

  • The distance between vehicles differs depending on the vehicle speed, and the slower the vehicle speed, the shorter the distance.

  • When the ignition is switched to ACC or OFF and then the engine is started again, the system automatically sets the distance between vehicles to the previous setting.

  • When accelerating using the SET switch while in headway control, the set vehicle speed can be adjusted but acceleration is not possible. If there is no longer a vehicle ahead, acceleration continues until reaching the set vehicle speed. Check the set vehicle speed by viewing the set vehicle speed display in the display in the instrument cluster.

  • When depressing the accelerator pedal, the inter-vehicle distance display in the display in the instrument cluster changes to the white-line display.

  • The minimum settable speed is 30 km/h (19 mph). If the set vehicle speed reaches 30 km/h (19 mph) using the switch operation, constant speed travel is maintained at about 30 km/h (19 mph) even if the SET switch is pressed. The Mazda Radar Cruise Control (MRCC) system is not cancelled.
