MAZDA CX9 2023 Owners Manual

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.
