Mazda Radar Cruise
Control (MRCC) (Manual
Transmission)
*
▼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
front radar sensor 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.
Front radar sensor (page 4-204)
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 safe 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 traffic is heavy with insufficient
space between vehicles, or roads where
frequent and repetitive acceleration and
deceleration occur (Driving under these
conditions using the MRCC is not
possible).
 When entering and exiting interchanges,
service 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).
