Increasing speed with a single
RESUME/
switch operation
Instrument cluster display for vehicle
speed indicated in km /h: 1 km/h (0.6 mph)
Instrument cluster display for vehicle
speed indicated in mph: 1 mph (1.6 km/h)
To increase speed using accelerator
pedal
Depress the accelerator pedal to accelerate
to the desired speed. Press the SET/
switch and release it immediately.
NOTE
Accelerate if you want to speed up
temporarily when the cruise control is on.
Greater speed will not interfere with or
change the set speed. Take your foot off
the accelerator to return to the set speed.
▼ To Decrease Cruising Speed
Press the SET/ switch and hold it. The
vehicle will gradually slow.
Release the switch at the desired speed.

Press the SET/
switch and release it
immediately to adjust the preset speed.
Multiple operations will decrease the
preset speed according to the number of
times it is operated.
Decreasing speed with a single SET/
switch operation
Instrument cluster display for vehicle
speed indicated in km /h: 1 km/h (0.6 mph)
Instrument cluster display for vehicle
speed indicated in mph: 1 mph (1.6 km/h)
▼ To Resume Cruising Speed at More
Than 25 km/h (16 mph)
If the cruise control system 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 RESUME/
switch is
pressed.
If vehicle speed is below 25 km/h (16
mph), increase the vehicle speed up to 25
km/h (16 mph) or more and press the
RESUME/
switch.
▼ To Te m p o r a 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 OFF/CANCEL switch.
If the RESUME/
switch is pressed when
the vehicle speed is 25 km/h (16 mph) or
higher, the system reverts to the previously
set speed.
NOTE
If any of the following conditions occur,
the cruise control system is temporarily
canceled.
The parking brake is applied.
The selector lever is in the P or N
position.
When the cruise control system is
temporarily canceled by even one of the
applicable cancel conditions, the speed
cannot be re-set.
The cruise control cannot be cancelled
while driving in manual mode (selector
lever shifted from D to M position).
Therefore, engine braking will not be
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.

Diesel Particulate Filter(SKYACTIV-D 2.2)
The diesel particulate filter collects and
removes most of the particulate matter
(PM) in the exhaust gas of a diesel engine.
PM collected by the diesel particulate
filter is cleared during normal driving,
however, PM may not be removed and the
diesel particulate filter indicator light may
illuminate under the following conditions:
If the vehicle is driven at 15 km/h (9
mph) or less continuously.
If the vehicle is repeatedly driven for a
short period of time (10 minute or less)
or driven while the engine is cold.
If the vehicle is idled for a long time.
When “DPF Clogged” is indicated
The particulate matter (PM) cannot be
removed automatically and the amount of
collected PM reaches a specified amount.
After the engine has sufficiently warmed
up (engine coolant temperature of 80 °C
(176 °F) or more), depress the accelerator
pedal and drive the vehicle at a speed of
20 km/h (12 mph) or more for about 15 to
20 minutes to eliminate the PM.
When “DPF malfunction” is indicated
Contact an Authorized Mazda Dealer.
CAUTION
If the vehicle continues to be driven with
“DPF Clogged” indicated in the display, the
particulate matter (PM) increases and the
indication may change to “DPF
malfunction”. If the indication changes to
“DPF malfunction”, have the vehicle
inspected immediately at an Authorized
Mazda Dealer. If the vehicle is not
inspected and continues to be driven, the
engine may malfunction.
NOTE
When “DPF malfunction” is indicated
in the display, the engine output is
restricted to protect the diesel
particulate filter.
The engine sound and exhaust gas smell
may change when PM is being removed
while driving.

Selective Catalytic Reduction (SCR) System*
The SCR system is designed to reduce nitrogen oxide (NOx) in the exhaust gas and purify
the exhaust gas by injecting it with Diesel Exhaust Fluid (DEF).
WARNING
Be careful not to allow the DEF to run out. If the DEF completely runs out, the SCR system will
not operate normally.
When the remaining DEF is low, a message is displayed on the multi-information display, and
the SCR warning light turns on/flashes.
Refer to Selective Catalytic Reduction (SCR) System Indications on page 4-261.
In this case, consult an Authorized Mazda Dealer. If DEF needs to be replenished, add DEF
following the specified procedure.
Refer to Diesel Exhaust Fluid (DEF) Replenishment on page 6-30.
NOTE
DEF needs to be replenished periodically according to the scheduled maintenance
information.
Normally, the vehicle can be driven about 12,000 km (7,500 miles) before the DEF needs
to be replenished. However, it may need to be replenished earlier depending on the
driving and environmental conditions (such as putting a high load on the engine while
driving or driving the vehicle at high altitudes).
The sound of the SCR system operating may be heard from the area under the vehicle,
however, this does not indicate a problem.
▼ Selective Catalytic Reduction
(SCR) System Indications
As the remaining amount of Diesel Exhaust Fluid (DEF) lowers, the SCR system notifies
the driver using the following indications.
The vehicle speed may be restricted for a while even if the warning light turns off after
replenishing the DEF. To cancel the vehicle speed restriction immediately, switch the
ignition OFF after the warning light turns off and then switch the ignition ON again.

Anything which generates ultrasound is near the vehicle, 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.
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.
An obstruction is too close to the sensor.
Obstructions under the bumper may not be detected. Obstructions that are lower than the
bumper or thin which may have been initially detected may no longer be detected as the
vehicle approaches more closely to the obstruction.
The following types of obstructions may not be detected:
Thin objects such as wire or rope
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.
The system may have a malfunction if the beep does not operate or the indicator light
does not illuminate when the parking sensor switch is turned on. Consult an Authorized
Mazda Dealer.
The system may have a malfunction if the beep sound which indicates a system
malfunction is heard and the i ndicator light flashes. Consult an Authorized Mazda Dealer.
The beeper which indicates a system malf unction may not be heard if the ambient
temperature is extremely cold, or mud, ice, or snow adheres to the sensor area. Remove
any foreign material from the sensor area.
When installing a trailer hitch, consult an Authorized Mazda Dealer.
