Cruise Set Indication (Green)
The indication turns on (green) when a
cruising speed has been set.
▼Activation/Deactivation
WARNING
Always turn o
ff the cruise control
system when it is not in use:
Leaving the cruise control system in an
activation-ready state while the cruise
control is not in use is dangerous as the
cruise control could unexpectedly
activate if the activation button is
accidentally pressed, and result in loss
of vehicle control and an accident.
NOTE
When the ignition is switched OFF, the
system status before it was turned o ff is
maintained. For example, if the
ignition is switched OFF with the cruise
control system operable, the system
will be operable when the ignition is
switched ON the next time.
Activation
To activate the system, press the cruise
switch. The cruise standby indication
(white) turns on.
Deactivation
To deactivate the system, press the
cruise switch again.
The cruise standby indication (white)
turns off .
▼To Set Speed
1. Activate the cruise control system
by pressing the cruise switch. The
cruise standby indication (white)
turns on.
2. Accelerate to the desired speed, which must be more than 25 km/h
(16 mph).
3. Adjust the system to the desired vehicle speed using the accelerator
pedal. Press the RES switch up (SET
+) or down (SET -) to start cruise
control. The cruise control
indication (green) in the instrument
cluster turns on at the same time.
Quickly release the switch when the
cruise control indication (green)
turns on.
NOTE
If the RES switch is operated up (SET
+) or down (SET -) while the vehicle
speed is between 25 and 30 km/h
(16 to 19 mph), the set speed is set
to 30 km/h (19 mph).
The cruise control speed setting
cannot be performed under the
following conditions:
Any of the doors is opened.The driver's seat belt is unfastened.The brake pedal is depressed.The parking brake is applied.(Automatic transmission)
The selector lever is in the P, N, or
R position.
(Manual transmission)

continuously until the set speed
displayed in the instrument cluster and
on the active driving display is reached.
If you want to stop accelerating/
decelerating , change the set speed or
cancel the system (such as by
depressing the brake pedal).
To increase speed using accelerator
pedal
Depress the accelerator pedal and
press the RES switch up (SET+) or
down (SET
-) 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.
NOTE

▼To Resume Cruisi
ng Speed at More
Than 30 km/h (19 mph)
If the cruise control system is
temporarily canceled (such as by
applying the brake pedal) and the
system is still activated, the most
recent set speed will automatically
resume when the RES switch is
pressed.
If vehicle speed is below 30 km/h (19
mph), increase the vehicle speed up to
30 km/h (19 mph) or more and press
the RES switch.
▼ To Te m p o ra r i l y C a n c e l
To temporarily cancel the system, use
one of these methods:
Slightly depress the brake pedal.Press the CANCEL switch.(Manual transmission)
Depress the clutch pedal.
If the RES switch is pressed when the
vehicle speed is 30 km/h (19 mph) or

(Manual transmission)
The shift lever is in the neutral
position.
When the cruise control system is
temporarily canceled by even one of
the applicable cancel conditions, the
speed cannot be re-set.
(Automatic transmission)
The cruise control cannot be
canceled while driving in manual
mode (selector lever shifted from D
to M position). Therefore, engine
braking will not be applied even if
the transmission is shifted down to a
lower gear. If deceleration is
required, lower the set speed or
depress the brake pedal.

CAUTION
Do not install any accessories within the detection ranges of the sensors. It may
a ff ect the system operation.
 Depending on the type of obstruction and the surrounding conditions, the
detection range of a sensor may narrow, or the sensors may not be able to detect
obstructions.
NOTE
When the ignition is switched OFF, the system status before it was turned off is
maintained. For example, if the ignition is switched OFF while the parking sensor
is activated, the system will be activate d when the ignition is switched ON the
next time.
The system may not operate normally under the following conditions:
Mud, ice, or snow is adhering to the sensor area (Returns to normal operation
when removed).
The sensor area is frozen (Returns to normal operation when the ice is thawed).The sensor is covered by a hand.The sensor is excessively shocked.The vehicle is excessively tilted.Under extremely hot or cold weather conditions.The vehicle is driven on bumps, inclines, gravel, grating, or grass covered roads.Anything which generates ultrasonic wave s such as another vehicle's horn, the
engine sound of a motorcycle, the air brake sound of a large-sized vehicle, or
another vehicle's sensors approaches the vehicle.
The vehicle is driven in heavy rain or in road conditions causing water-splash.A commercially-available fender pole or an antenna for a radio transmitter is
installed to the vehicle.
The vehicle is moving towards a tall or square curbstone, or a steep grade.An obstruction is too close to the sensor.The vehicle is moving towards an uneven wall or stairs.There are multiple obstructions.The vehicle is driven in a place with low ceilings.Obstructions under the bumper cannot be detected. Obstructions which are
lower than the sensor or thin may not be detected even though they were
detected once.
The following types of obstructions may not be detected:
Thin objects such as wire, rope or polesThings which absorb sonic waves easily such as cotton or snowAngular shaped objectsVery tall objects, and those which are wide at the topSmall, short objectsAlways have the system inspected at an Authorized Mazda Dealer if any shock is
applied to the bumpers, even in a minor accident. If the sensors are deviated, they
cannot detect obstructions.
