Distance Recognition Support System (DRSS)*
The DRSS measures the distance between your vehicle and a vehicle ahead using a radar
sensor (front) while the vehicle speed is about 30 km/h (19 mph ) or faster, and if your
vehicle approaches a vehicle ahead more closely than what is ap propriate for maintaining
distance between the vehicles according to the vehicle speed, a notification in the active
driving display is indicated to advise you to keep a safe dista nce from the vehicle ahead.
WA R N I N G
Do not rely completely on the DRSS and always drive carefully:
The ability to detect a vehicle ahead is limite d depending on the type of vehicle ahead, the
weather conditions, and the traffic conditions. Therefore, if the accelerator and brake pedals
are not operated correctly it could lead to an accident. Always verify the safety of the
surrounding area and depress the brake pedal or accelerator pedal while keeping a safer
distance from vehicles ahead or on-coming vehicles.
NOTE
•The DRSS operates when all of the following conditions are met:
•The ignition is switched ON.
•The DRSS is on.
•The selector lever is in a position other than reverse (R).
•The vehicle speed is 30 km/h or faster (19 mph or faster).
•The objects which activate the system are 4-wheeled vehicles.
•The DRSS may also operate in the presence of motorcycles and bicycles.
•The DRSS may not operate normally under the following conditions:
•The Dynamic Stability Control (DSC) has a malfunction.
•The vehicle ahead is traveling at an extremely slow speed.
•The system does not operate with the following objects:
•Vehicles approaching in the opposite direction.
•Stationary objects (stopped vehicles, obstructions)

Mazda Radar Cruise Control with Stop & Go function(MRCC with Stop & Go function)
*
The MRCC with Stop & Go function 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 Mazda Radar Cr uise Control (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.
If the vehicle ahead stops while you are following behind it, your vehicle will stop and be
held stopped automatically (stop hold control), and headway con trol will resume when you
resume driving the vehicle such a s by pressing the RES switch.
Also refer to the following before using the MRCC with Stop & G o function.
•AUTOHOLD (page 4-61)
•Forward Sensing Camera (FSC) (page 4-130)
•Radar sensor (front) (page 4-135)
WA R N I N G
Do not rely completely on the MRCC with Stop & Go function:
The MRCC with Stop & Go function system has detection limitations depending on the type of
vehicle ahead and its conditions, the weat her 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 sudd enly 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 with Stop & Go function system in the following locations, using the
MRCC with Stop & Go function system at the following locations may result in an unexpected
accident:
 General roads other than highways (Driving under these conditions using the MRCC with
Stop & Go function system is not possible.)
 Roads with sharp curves and where vehicle
traffic is heavy and there is
insufficient space
between vehicles.

*Some models.4-107
CX-3_8GR7-EA-18B_Edition1 2017-12-20 16:18:14

•During headway control travel, the system accelerates and decelerates your vehicle in
conjunction with the speed of the vehicle ahead. However, if it is necessary to accelerate
for a lane change or if the vehicle ahead brakes suddenly causing you to close in on the
vehicle rapidly, accelerate using the accelerator pedal or decelerate using the brake
pedal depending on the conditions.
•While the MRCC with Stop & Go function system is in use, it does not cancel even if the
selector lever is operated and any intended engine braking does not occur. If deceleration
is required, lower the set speed or depress the brake pedal.
•The sound of the automatic brakes operating may be heard, however, it does not indicate
a problem.
•The brake lights turn on while the MRCC with Stop & Go function automatic braking is
operating, however, they may not turn on while the vehicle is on a downslope at the set
vehicle speed or traveling at a constant speed and following a vehicle ahead.
