▼ Mazda Radar Cruise Control with
Stop & Go function (MRCC with
Stop & Go function)
The MRCC with Stop & Go function is
a system designed to enable
constant-speed driving at a set speed
and headway control to maintain a
constant distance with a vehicle ahead
according to your vehicle speed. The
system automatically accelerates,
decelerates, and stops your vehicle
without you having to depress the
accelerator or brake pedal.
Also refer to the following information
before using the MRCC with Stop &
Go function.
Refer to Forward Sensing Camera
(FSC) on page 4-189.
Refer to Front Radar Sensor on page
4-193.
WARNING
Do not rely completely on the MRCC
with Stop & Go function and always
drive carefully:
The MRCC with Stop & Go function
may not be able to detect a vehicle
ahead depending on the type of
vehicle and its conditions, the weather
conditions, and the road conditions.
Additionally, the system might be
unable to decelerate sufficiently if the
vehicle ahead applies the brakes
suddenly or another vehicle cuts into
your lane, which could result in an
accident.
Always check the surrounding
conditions and depress the brake
pedal or accelerator pedal while
keeping a safe distance from a vehicle
ahead or a vehicle following behind
you.
Do not use the system under the
following conditions. Otherwise, it
may result in an accident:
The vehicle is driven on roads other
than highways.
The vehicle is driven on roads with
sharp curves or with heavy traffic
where sufficient distances between
vehicles cannot be kept.
The vehicle is driven on roads where
acceleration and deceleration are
frequently repeated.
The vehicle is exiting the main lane
on an expressway to enter an
interchange, a rest area, or a parking
area.
The vehicle is driven on slippery
roads such as icy roads,
snow-covered roads, and unpaved
roads.
The vehicle is driven on a long
downslope.
The vehicle is driven on a steep
slope.
A two-wheeled vehicle such as a
motorcycle or bicycle is traveling
ahead.
The vehicle is being towed or towing
another vehicle.
Proximity warnings activate
frequently.
Switch the MRCC with Stop & Go
function off when it is not being used.
Leaving the MRCC with Stop & Go
function on when it is not in use is
dangerous as it could operate
unexpectedly, resulting in an accident.
