2018 MAZDA MODEL CX-9 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 wi thout 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 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, y our vehicle will stop and be
held stopped automatically (stop hold control), and headway con trol will resume when you
resume driving the vehicle such as by pressing the RES switch.
Also refer to the following befo re using the MRCC with Stop & G o function.
•Forward Sensing Camera (FSC) (page 4-145)
•Radar sensor (front) (page 4-150)
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 weather conditions, and the road conditions.
Additionally, the system may be unable to dece lerate 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 surroundi ng 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 high ways (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.
 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).

CX-9_8GC3-EA-17G_Edition1 2017-5-29 10:13:38

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 a ccelerate 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 distance 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 electric parking brake (EPB).
CAUTION
If your vehicle is towed or you are towing something, switch the MRCC with Stop & Go
function system off to prevent a miss-operation.
NOTE
•The MRCC with Stop & Go function system do es 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.

Lane-keep Assist System (LAS) & Lane DepartureWarning System (LDWS)
*
The LAS&LDWS alerts the driver th at the vehicle may be deviating from its lane and it
provides steering assistance to help the driver stay within the vehicle lanes.
The Forward Sensing Camera (FSC) detects the white lines (yello w lines) of the vehicle
lane in which the vehicle is traveling and if the system determ ines that the vehicle may
deviate from its lane, it operates the electric power steering to assist the driver's steering
operation. The system also alerts the driver by activating a la ne departure warning sound,
vibrating the steering wheel, and indicating an alert in the di splay. Use the system when you
drive the vehicle on ro ads with white (yellow) lines such as ex pressways and highways.
Refer to Forward Sensing Camera (FSC) on page 4-145.
