When Driving
Tyre Pressure Monitoring System
Tyre Pressure Monitoring System *
The Tyre Pressure Monitoring System (TPMS) monitors the air pressure of all four tyres. If
the air pressure of one or more tyres is too low, the system warns the driver by indicating the
tyre pressure monitoring system warning light in the instrument cluster and operating a beep
sound. The system monitors the tyre pressures indirectly using the data sent from the ABS
wheel speed sensors.
To allow the system to operate correctly, the system needs to be initialized with the specifi ed
tyre pressure (value on the tyre pressure label). Follow the procedure and perform the
initialization.
Refer to Tyre Pressure Monitoring System Initialization on page 4-164 .
The warning light fl ashes when the system has a malfunction.
Refer to Warning Lights on page 4-41 .

When Driving
Tyre Pressure Monitoring System
NOTE
Because this system detects slight changes in tyre conditions, the timing of the warning
may be faster or slower in the following cases:
 
 The size, manufacturer, or the type of tyres is different from the specifi cation. 
 The size, manufacturer, or the type of a tyre is different from the others, or the level of
tyre wear is excessively different between them.
  A run-fl at tyre, studless tyre, snow tyre, or tyre chains are used. 
 An emergency tyre is used (The tyre pressure monitoring system warning light may
fl ash and then continue illuminating).

 A tyre is repaired using the emergency fl at tyre repair kit. 
 The tyre pressure is excessively higher than the specifi ed pressure, or the tyre pressure
is suddenly lowered for some reason such as a tyre burst during driving.
  The vehicle speed is lower than about 15 km/h (9.3 mph) (including when the vehicle
is stopped), or the drive period is shorter than 5 minutes.
  The vehicle is driven on an extremely rough road or a slippery, icy road. 
 Hard steering and rapid acceleration/deceleration are repeated such as during
aggressive driving on a winding road.
  Load on the vehicle is applied to a tyre such as by loading heavy luggage to one side of
the vehicle.
  System initialization has not been implemented with the specifi ed tyre pressure.

When Driving
Tyre Pressure Monitoring System
Tyre Pressure Monitoring System
Initialization
In the following cases, system
initialization must be performed so that the
system operates normally.
 


 A tyre pressure is adjusted.



 Tyre rotation is performed.



 A tyre or wheel is replaced.



 The battery is replaced or completely
drained.
 


 The tyre pressure monitoring system
warning light is illuminated.
Initialization method
1. Park the car in a safe place and fi rmly
apply the parking brake.
2. Let the tyres cool, then adjust the tyre
pressure of all four (4) tyres to the
specifi ed pressure indicated on the tyre
pressure label located on the door jamb
of the driver's door (door open).
Refer to Tyres on page 9-13 .
3. Switch the ignition ON.
4. While the vehicle is parked, press
and hold the tyre pressure monitoring
system set switch and verify that
the tyre pressure monitoring system
warning light in the instrument cluster
fl ashes twice and a beep sound is heard
once.
CAUTION
If the system initialization is performed
without adjusting the tyre pressure, the
system cannot detect the normal tyre
pressure and it may not illuminate the
tyre pressure monitoring system warning
light even if a tyre pressure is low, or
it may illuminate the light even if the
pressures are normal.
Adjust the tyre pressure on all four
tyres and initialize the system when
the warning light is turned on. If the
warning light turns on for a reason other
than a fl at tyre, the tyre pressure of all
four tyres may have decreased naturally.
The system initialization will not be
performed if the switch is pressed while
the vehicle is being driven.

When Driving
Diesel Particulate Filter (SKYACTIV-D 2.2)
Diesel Particulate Filter
(SKYACTIV-D 2.2)
The diesel particulate fi lter collects and
removes most of the particulate matter
(PM) in the exhaust gas of a diesel engine.
PM collected by the diesel particulate
fi lter is cleared during normal driving,
however, PM may not be removed and the
diesel particulate fi lter 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.
NOTE
The engine sound and exhaust gas smell
may change when PM is being removed
while driving.
Diesel Particulate Filter Indicator Light
When illuminated
The particulate matter (PM) cannot be
removed automatically and the amount of
collected PM reaches a specifi ed amount.
After the engine has suffi ciently warmed
up (engine coolant temperature of 80 °C
or more), depress the accelerator pedal and
drive the vehicle at a speed of 20 km/h
or more for about 15 to 20 minutes to
eliminate the PM. When fl ashing
Contact an expert repairer, we recommend
an Authorised Mazda Repairer.
CAUTION
If the vehicle is continually driven as
usual with the diesel particulate fi lter
indicator light illuminated, PM increases
and the indicator light may start fl ashing.
If the diesel particulate fi lter indicator
light starts fl ashing, have the vehicle
inspected immediately at an expert
repairer, we recommend an Authorised
Mazda Repairer. If the vehicle is not
inspected and continues to be driven, the
engine may malfunction.
NOTE
When the diesel particulate fi lter
indicator light fl ashes, the engine
output is restricted to protect the diesel
particulate fi lter.
