cruise control MAZDA MODEL 3 HATCHBACK 2018 (in English) User Guide

Mazda Radar Cruise Control (MRCC)*
The MRCC system is designed to maintain headway control*1 with a vehicle ahead
according to your vehicle's speed using a radar sensor (front) to detect the distance to the
vehicle ahead and a preset vehicle speed without you having to use the accelerator or brake
pedals.
*1 Headway Control: Control of the distance between your vehicle and the vehicle ahead
detected by the MRCC system.
Additionally, if your vehicle starts closing in on the vehicle ahead such as if the vehicle
ahead brakes suddenly, a warning sound and a warning indication in the display are
activated simultaneously to alert you to maintain a sufficient distance between the vehicles.
Also refer to the following before using the MRCC.
Radar sensor (front) (page 4-136)
WA R N I N G
Do not rely completely on the MRCC:
The MRCC system has detection limitations depending on the type of vehicle ahead and its
conditions, the weather conditions, and the road conditions. Additionally, the system may be
unable to decelerate sufficiently to avoid hitting the vehicle ahead if the vehicle ahead applies
the brakes suddenly or another vehicle cuts into the driving lane, which could result in an
accident.
Always drive carefully and verify the surrounding conditions and depress the brake pedal or
accelerator pedal while keeping a safer distance from vehicles ahead or on-coming vehicles.
Do not use the MRCC system in the following locations, using the MRCC system at the
following locations may result in an unexpected accident:
 General roads other than highways (Driving under these conditions using the MRCC system
is not possible.)
 Roads with sharp curves and where vehicle tr affic is heavy and there is insufficient space
between vehicles.
 Roads where frequent and repeti tive acceleration and deceleration occur (Driving under
these conditions using the MRCC system is not possible).
 When entering and exiting interchanges, servic e areas, and parking areas of highways (If
you exit a highway while headway control is in use, the vehicle ahead will no longer be
tracked and your vehicle may accelerate to the set speed).
 Slippery roads such as ice or snow-bound roads (Tires could sp in causing you to lose vehicle
control, or the stop hold control may not operate.)
 Long, descending slopes (to maintain distan ce between vehicles, the system automatically
and continuously applies the brakes which could result in the loss of brake power.)
