Mazda Radar Cruise Control (MRCC) (Manual Transaxleand Taiwan)
*
The MRCC system is designed to maintain headway control*1 with a vehicle ahead
according to your vehic le'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 s tarts 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 4-201)
WA R N I N G
Do not rely completely on the MRCC:
The MRCC system has detection limitations depe nding 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 hittin g 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 repetitive accelerati on 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 a ccelerate to the set speed).
Slippery roads such as ice or snow-bound roads (Tyres could spin causing you to lose
vehicle control, or the stop hold control may not operate.)

If there is a problem with the MRCC system, a message is displayed on the
multi-information disp lay. Check the centre display to verify the problem and then have
your vehicle inspected by an expert repairer, we recommend an A uthorised Mazda Repairer.
Refer to Message Indicated on Display on page 7-61.
▼ Close Proximity Warning
If your vehicle rapidly closes in
on the vehicle ahead because the vehicle ahead applies the
brakes suddenly while you are travelling in headway control, th e warning sound activates
and the brake warning is indicated in the display. Always verif y the safety of the
surrounding area and depress the brake pedal while keeping a sa fer distance from the
vehicle ahead. Additionally, keep a safer distance from the veh icles behind you.

Roads with sharp curves and where vehicle
traffic is heavy and there is
insufficient space
between vehicles.
Roads where frequent and repetitive accelerati on and deceleration occur (Driving under
these conditions using the MRCC with Stop & Go function 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 (Tyres could spin causing you to lose
vehicle control, or the stop hold control may not operate.)
Long, descending slopes (to maintain distance between vehicles, the system automatically
and continuously applies the brakes which could result in the loss of brake power.)
Slopes with a steep gradient (The vehicle ahea d may not be detected correctly, your vehicle
may slide while stopped by the stop hold control, and it may accelerate suddenly after it
starts moving.)
