WARNING
Do not rely completely on the Mazda Radar Cruise Control (MRCC) system and always
drive carefully:
The Mazda Radar Cruise Control (MRCC) system is designed to reduce load on the
driver, and although it maintains a constant vehicle speed, or specifi cally, it maintains
a constant distance between your vehicle and the detected vehicle ahead according to
the vehicle speed, the 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 decelerate suffi ciently to avoid hitting the vehicle ahead
if the vehicle ahead applies the brakes suddenly or another vehicle cuts into the driving
lane, which could result in 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.

Do not use the Mazda Radar Cruise Control (MRCC) system in the following locations.
Otherwise, it could lead to an accident:
 


¾ Roads with sharp curves and where vehicle traffi c is heavy and there is insuffi cient
space between vehicles. Roads where frequent and repetitive acceleration and
deceleration occur (Driving under these conditions using the Mazda Radar Cruise
Control (MRCC) system is not possible).
 


¾ When entering and exiting interchanges, service 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).
 


¾ Slippery roads such as ice or snow-bound roads (The tires could spin causing you to
lose vehicle control).
 


¾ 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).

For the purposes of safety, switch the Mazda Radar Cruise Control (MRCC) system off
when it is not being used.
CAUTION
If the vehicle is towed or you are towing something, switch the Mazda Radar Cruise
Control (MRCC) system off to prevent an incorrect operation.

NOTE
 


y The Mazda Radar Cruise Control (MRCC) system operates when all of the following
conditions are met.
 


y The vehicle speed is about 30 km/h (19 mph) to 145 km/h (90 mph).



y The Mazda Radar Cruise Control (MRCC) system is turned on.



y The parking brake is not applied.



y The Smart Brake Support (SBS) is not malfunctioning.



y The Dynamic Stability Control (DSC) is operating normally.



y The selector lever is in the drive (D) position or manual (M) position (manual mode).




y In the following cases, the warnings may not activate even if your vehicle starts closing in
on the vehicle ahead.
 


y You are driving at the same speed as the vehicle ahead.



y Directly after the Mazda Radar Cruise Control (MRCC) system has been set.



y When the accelerator pedal is depressed or directly after the accelerator pedal is
released.
 


y Another vehicle cuts into the driving lane.




y The following are not detected as physical objects.




y Vehicles approaching in the opposite direction



y Pedestrians



y Stationary objects (stopped vehicles, obstructions)




y If a vehicle ahead is traveling at an extremely low speed, the system may not detect it
correctly.
 


y During headway control travel, do not set the system on two-wheeled vehicles such as
motorcycles and bicycles.
 


y Do not use the Mazda Radar Cruise Control (MRCC) system under conditions in which
the close proximity warnings are frequently activated.
 


y 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.
 


y While the Mazda Radar Cruise Control (MRCC) system is in use, it does not cancel
even if the selector 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.
 


y The brake lights are illuminated while the Mazda Radar Cruise Control (MRCC)
automatic braking is operating.

NOTE
 


y The Mazda Radar Cruise Control
(MRCC) system may be canceled during
rain, fog, snow or other inclement
weather conditions, or the front surface
of the radiator grille is dirty.
 


y If you have temporarily canceled the
Mazda Radar Cruise Control (MRCC),
you can return to your previously set
speed by pressing the RES switch and
after all of the operation conditions
have been met.
 


y If the OFF switch is pressed to cancel
the Mazda Radar Cruise Control
(MRCC), the system does not return to
the previously set speed even if the RES
switch is pressed.
Cruise Control Function
While this function is operating, the
headway control operation is canceled and
only the cruise control function operates.
The vehicle speed can be set more than
about 25 km/h (16 mph).
Use the cruise control function on
expressways and other highways which do
not require a lot of repeated acceleration
and deceleration.
WARNING
Do not use the cruise control function in
the following locations:
Otherwise, it could lead to an accident.
 


¾ Roads with sharp curves and where
vehicle traffi c is heavy and there is
insuffi cient space between vehicles.
(Driving under these conditions
using the cruise control function is
not possible)
 


¾ Steep down slopes (Set speed may
be exceeded because suffi cient
engine braking cannot be applied)
 


¾ Slippery roads such as ice or snow-
bound roads (Tires could spin
causing you to lose vehicle control)

Always drive carefully:
The warnings and brake control
will not operate after the headway
control function is canceled and the
system is switched to only the cruise
control function. Depress the brake
pedal to decelerate according to the
surrounding conditions while keeping
a safer distance from the vehicle ahead
and always driving carefully.

Switching to cruise control function
When the ON switch is pressed
continuously for about 2 seconds while
the Mazda Radar Cruise Control (MRCC)
system is turned on, the system is switched
to the cruise control function.
The Mazda Radar Cruise Control (MRCC)
indicator light (green) in the instrument
cluster turns off and the cruise control
indication is displayed in the active
driving display.
WARNING
Always turn off the cruise control
function when it is not in use:
Leaving the cruise control function
turned on when it is not in use
is dangerous as it could operate
unexpectedly, resulting in an accident.
How to set the speed
Adjust the system to the desired vehicle
speed using the accelerator pedal.
Cruise control function begins when the
SET
or SET switch is pressed.
NOTE
 


y The system may not be able to maintain
the set speed constantly depending on
driving conditions such as steep up or
down slopes.
 


y The speed will continue increasing
while the SET
switch is pressed and
held. The speed will continue
decreasing while the SET
switch is
pressed and held.
How to increase the set speed
The set speed can be increased using the
following operations:
To increase speed using the SET
switch
Press and hold the SET
switch and
release the switch at the desired speed.
The set speed can be adjusted
incrementally (1 km/h (1 mph)
increments) by pressing the switch and
releasing it immediately. For example, if
the switch is pressed 4 times, the set speed
increases by about 4 km/h (4 mph).
To increase speed using accelerator
pedal
Depress the accelerator pedal and press the
SET
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.
How to Decrease the Set Speed
Press the SET
switch continuously and
release the switch at the desired speed.
The set speed can be adjusted
incrementally (1 km/h (1 mph) increments)
