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
multi-information display is indicated to advise you to keep a safe distance 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 limited depending on th e 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 po sition 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 Cruise 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 4-98)
Forward Sensing Camera (FSC) (page 4-239)
Radar sensor (front) (page 4-244)
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 tr affic is heavy and there is insufficient space
between vehicles.
When Driving
i-ACTIVSENSE
*Some models.4-145
CX-9_8LJ2-EA-22H_Edition1_old 2022-6-9 13:33:08

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 (Tires could spin 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.)
 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.)
For safety purposes, switch the MRCC with Stop & Go function system off when it is not being
used.
Do not get out of the vehicle while the stop hold control is operating:
Getting out of the vehicle while the stop hold co ntrol is operating is dangerous as the vehicle
may move unexpectedly and result in an accident. Before getting out of the vehicle, switch the
MRCC with Stop & Go function system off, shift the selector lever to the P position, and apply
the parking brake.
CAUTION
If your vehicle is towed or you are towing something, switch the MRCC with Stop & Go
function system off to prevent a mis-operation.
NOTE
The MRCC with Stop & Go function system does not detect the following as physical
objects.
Vehicles approaching in the opposite direction
Pedestrians
Stationary objects (stopped vehicles, obstructions)
If a vehicle ahead is traveling at an extremely low speed, the system may not detect it
correctly.
During headway control travel, do not set the system for detection of two-wheeled
vehicles such as motorcycles and bicycles.
Do not use the MRCC with Stop & Go function system under conditions in which close
proximity warnings are frequently activated.

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.
