y Power steering is only operable when
the engine is running. If the engine is
off or if the power steering system is
inoperable, you can still steer, but it
requires more physical effort.
  If the steering feels stiffer than usual
during normal driving or the steering
vibrates, consult an Authorized Mazda
Dealer.
 


y The warning light noti¿ es the driver
of system abnormalities and operation
conditions.
  In addition, the buzzer may also activate
depending on the system abnormality or
operation condition.
  Refer to Warning Lights on page
4-21 .
  Refer to Power Steering Warning Buzzer
on page 7-38 .

CAUTION
Never hold the steering wheel to the
extreme left or right for more than 5
seconds with the engine running. This
could damage the power steering
system.

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 (automatic transaxle)/shift lever (manual transaxle) 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.
 


y The Mazda Radar Cruise Control (MRCC) warning light (amber) turns on when the
system has a malfunction.
  Refer to Warning/Indicator Lights on page 4-20 .
Mazda Radar Cruise Control (MRCC) Display Indication
The setting status and operation conditions of the Mazda Radar Cruise Control (MRCC)
system are indicated in the active driving display.

Close Proximity Warning
If your vehicle rapidly closes in on the vehicle ahead because the vehicle applies the brakes
suddenly while you are traveling in headway control, the warning sound activates and
the brake warning is indicated in the display. Always verify the safety of the surrounding
area and depress the brake pedal while keeping a safer distance from the vehicle ahead.
Additionally, always keep a safer distance from the vehicles behind you.

Distance-between-
vehicles guideline

vehicle speed) Indication on display
Short (about 30 m (98
ft))


Extremely short (about
25 m (82 ft))



N O T E
 


y The distance between vehicles differs
depending on the vehicle speed, and the
slower the vehicle speed, the shorter the
distance.
 


y When the ignition is switched to ACC
or OFF and then the engine is started
again, the system automatically sets
the distance between vehicles to the
previous setting.

Changing the Set Vehicle Speed
Changing the set vehicle speed using the
SET switch
Press the SET
switch to accelerate.
Press the SET
switch to decelerate.
The set vehicle speed changes as follows
each time the SET switch is pressed.

Short press 1 km/h (1 mph)
Long press 10 km/h (5 mph)

N O T E
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 accelerate using the accelerator
pedal
Depress the accelerator pedal and press
and release the SET
or SET switch at
the desired speed. If a switch cannot be
operated, the system returns to the set
speed when you release your foot from the
accelerator pedal.
CAUTION
The warnings and brake control do not
operate while the accelerator pedal is
depressed.

N O T E
 


y 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. Check the set vehicle speed by
viewing the set vehicle speed display in
the active driving display.
 


y When depressing the accelerator pedal,
the inter-vehicle distance display in the
active driving display changes to the
white-line display.
 


y The minimum settable speed is 30 km/h
(19 mph). If the set vehicle speed
reaches 30 km/h (19 mph) using the
switch operation, constant speed travel
is maintained at about 30 km/h (19
mph) even if the SET
switch is
pressed. The Mazda Radar Cruise
Control (MRCC) system is not canceled.

CAUTION
 


¾ When driving off -road in areas where there is grass or forage, it is recommended that the
Smart City Brake Support (SCBS) system be turned off .




¾ Always use tires for all wheels that are of the specifi ed size, and the same manufacturer,
brand, and tread pattern. In addition, do not use tires with signifi cantly diff erent wear
patterns on the same vehicle as the Smart City Brake Support (SCBS) system may not
operate normally.
 


¾ The laser sensor (front) includes a function for detecting a soiled windshield and informing
the driver, however, depending on the conditions, it may not detect plastic shopping bags,
ice or snow on the windshield. In such cases, the system cannot accurately determine a
vehicle ahead and may not be able to operate normally. Always drive carefully and pay
attention to the road ahead.

N O T E
 


y The Smart City Brake Support (SCBS) system will not operate if the driver is deliberately
performing driving operations (accelerator pedal and steering wheel).
 


y The Smart City Brake Support (SCBS) system will operate under the following conditions. 



y The engine is running.



y The Smart City Brake Support (SCBS) warning light (amber) does not illuminate.



y The vehicle speed is between about 4 to 30 km/h (2 to 18 mph).



y The Smart City Brake Support (SCBS) system is not turned off.



y The DSC operation is not turned off using the DSC OFF switch.



y The DSC is not malfunctioning. 



y The Smart City Brake Support (SCBS) detects a vehicle ahead by emitting a near-infrared
laser beam and receiving the beam reÀ ected off the reÀ ector of the vehicle ahead, and
then using it for the measurement. Consequently, the Smart City Brake Support (SCBS)
may not operate under the following conditions:
 


y ReÀ ection of the laser is poor due to the shape of the vehicle ahead.



y The vehicle ahead is signi¿ cantly dirty.



y Under bad weather condition, such as rain, fog and snow.



y The window washer is being used or the windshield wipers are not used when it's
raining.
 


y The windshield is dirty.



y The steering wheel is turned completely left or right, or the vehicle is accelerated
rapidly and comes close to the vehicle ahead.
 


y Trucks with low loading platforms and vehicles with an extremely low or high pro¿ le.



y Vehicles with certain shapes such as a vehicle carrier.

To Temporarily Cancel
To temporarily cancel the system, use one
of these methods:
 


y Slightly depress the brake pedal.



y (Manual transaxle) 
 Depress the clutch pedal.



y Press the CANCEL switch.
If the RESUME switch is pressed when
the vehicle speed is 25 km/h (16 mph) or

set speed.
N O T E
 


y If any of the following conditions occur,
the cruise control system is temporarily
canceled.
 


y The parking brake is applied.



y (Automatic transaxle) 
 The selector lever is in the P or N
position.
 


y (Manual transaxle) 
 The shift lever is in the neutral
position.
 


y When the cruise control system is
temporarily canceled by even one of the
applicable cancel conditions, the speed
cannot be re-set.
 


y (Automatic transaxle) 
 The cruise control cannot be cancelled
while driving in manual mode (selector
lever shifted from D to M position).

applied even if the transaxle is shifted
down to a lower gear. If deceleration is
required, lower the set speed or depress
the brake pedal.

To Deactivate
To deactivate the system, press the OFF
switch.
