2022 MAZDA MODEL CX-5 warning

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 starts closing in on the vehicle ahead such as if the vehicle
ahead brakes suddenly, a warning sound an d 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 follo wing behind it, your vehicle will stop and be
held stopped automatically (stop hold control), and headway control will resume when you
resume driving the vehicle such as by pressing the RES switch.
Also refer to the following before usin g the MRCC with Stop & Go function.
AUTOHOLD (page 4-99)
Forward Sensing Camera (FSC) (page 4-256)
Radar sensor (front) (page 4-261)
WARNING
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.

CX-5_8KN5-EA-21K_Edition1_old 2021-9-9 8:35:12

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.

How to change the set vehicle speed
To accelerate/decelerate using the SET
switch
When you press the SET
switch, the
vehicle accelerates and when you press the
SET
switch, it decelerates.
Short press 1 km/h (1 mph)
Long press 10 km/h (5 mph)
NOTE
For example, the set vehicle speed is
changed by pressing the SET switch four
times as follows:
The vehicle speed accelerates or
decelerates by 4 km/h (4 mph).
To increase speed using accelerator
pedal
Depress the accelerator pedal and press
and release the SET
switch or SET
switch at the desired speed. If the switch is
not operated, the system returns to the set
speed after you release your foot from the
accelerator pedal.
CAUTION

operate while the accelerator pedal is
depressed.
NOTE
The setting speed can be changed by
operating the SET
switch or SET
switch during stop hold control.
When accelerating using the SET
switch while in headway control, the set
vehicle speed can be adjusted but
acceleration is not possible. If there is
no longer a vehicle ahead, acceleration
continues until reaching the set vehicle
speed. For the set vehicle speed, check
the set vehicle speed indication in the
display.
