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 ahead may not be detected

correctly.)

Two-wheeled vehicles such as

motorcycles or bicycles are ahead.

For safety purposes, switch the MRCC

system o

 when it is not being used.

Leaving the MRCC system turned on

when it is not in use is dangerous as it

could operate unexpectedly, resulting

in an accident.

CAUTION

Turn the system o

 when the vehicle

is running on a chassis roller.

If your vehicle is towed or you are

towing something, switch the MRCC

system o

 to prevent an unexpected

operation.

NOTE

The MRCC 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.

If there is a structure on the road or

an object (such as a monorail) at a

low height o

 the ground in front of

the vehicle, the system may operate.

Therefore, do not use the MRCC.

Do not use the MRCC 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 system is in use, it

does not cancel even if the shift lever

is operated and any intended engine

braking will not occur. If deceleration

is required, lower the vehicle speed

setting or depress the brake pedal.

While braking by the MRCC control

is operating, you might hear an

operation sound, however, this does

not indicate a problem.

The brake lights turn on while

braking by the MRCC control is

operating, however, they may not

turn on while the vehicle is on a

down slope at the set vehicle speed

or traveling at a constant speed and

following a vehicle ahead.

Stop the headway control function to

switch the system to the cruise

control function.

Refer to the Settings section in the

Mazda Connect Owner's Manual.
