Theft-Deterrent System*
▼Theft-Deterrent System
If the theft-deterrent system detects an
inappropriate entry into the vehicle,
which could result in the vehicle or its
contents being stolen, the alarm alerts
the surrounding area of an abnormality
by sounding the horn and
flashing the
hazard warning lights.

The system will not function unless it's
properly armed. So when you leave the
vehicle, follow the arming procedure
correctly.
▼ Operation
System triggering conditions
The horn sounds intermittently and the
hazard warning lights

door-lock knob.
Forcing open a door, the hood or the
liftgate/trunk lid.
Opening the hood by operating the
hood release handle.
Switching the ignition ON without
using the push button start.
If the system is triggered again, the
lights and horn will activate until the
driver's door or the liftgate/trunk lid is
unlocked with the transmitter.
(With the advanced keyless function)
The lights and horn can also be
deactivated by touching the sensing
area of the door release touch sensor.
NOTE
If the battery goes dead while the
theft-deterrent system is armed, the
horn will activate and the hazard
warning lights will flash when the
battery is charged or replaced.
▼ How to Arm the System

▼Distance-to-empty
This displays the approximate distance
you can travel on the remaining fuel
based on the fuel economy.
The distance-to-empty will be
calculated and displayed every second.

NOTE
Even though the distance-to-empty
display may indicate a su
fficient
amount of remaining driving distance
before refueling is required, refuel as
soon as possible if the fuel level is
very low or the low fuel warning light
illuminates.
The display will not change unless
you add more than approximately 9
L (2.3 US gal, 1.9 Imp gal) of fuel.
The distance-to-empty is the
approximate remaining distance the
vehicle can be driven until all the
graduation marks in the fuel gauge
indicating the remaining fuel supply
disappear.
If there is no past fuel economy
information such as after first
purchasing your vehicle or the
information is deleted when the
battery cables are disconnected, the
actual distance-to empty/range may di ffer from the amount indicated.
▼ Average Fuel Economy
The average fuel economy is calculated
every 30 seconds from the total
traveled distance on the trip meter and
the total fuel consumption, and the
average fuel economy for either drive
information display is displayed.
The average fuel economy is also
displayed by a red arrow in the
instantaneous fuel economy display.

The average fuel economy and trip
meters can be reset by pressing the
INFO switch for 1.5 seconds or more
while in each mode. After the data is
cleared, the fuel consumption is
recalculated and the - - - L/100 km
(- - - mpg) for the 30 seconds prior to
it being displayed is indicated.
▼Current Fuel Economy
This displays the current fuel economy
by calculating the amount of fuel
consumption and the distance
traveled.

▼Indications
1. Manual shift mode indication
2. Gear position indication
Manual shift mode indication
In manual shift mode, the “M” of the
shift position indication in the
instrument panel illuminates.
Gear position indication
The numeral for the selected gear
illuminates.

NOTE
If the gears cannot be shifted down
when driving at higher speeds, the
gear position indication will
flash
twice to signal that the gears cannot
be shifted down (to protect the
transmission).
If the automatic transmission fluid
(ATF) temperature becomes too
high, there is the possibility that the
transmission will switch to automatic
shift mode, canceling manual shift
mode and turning o ff the gear
position indication illumination. This
is a normal function to protect the
AT. After the ATF temperature has
decreased, the gear position
indication illumination turns back on
and driving in manual shift mode is
restored.
▼ Manually Shifting Up
You can shift gears up by operating the
selector lever or the steering shift
switches
*.
M1 → M2 → M3 → M4 → M5 → M6
Using selector lever
To shift up to a higher gear, tap the
selector lever back + once.

Using steering shift switch*
To shift up to a higher gear with the
steering shift switches, pull the UP
switch (+/OFF) toward you once with
your fingers.

Mazda3_8JM2-EA -20H_Edition1_new 2020-7-10 17:21:34

WARNING
Do not use engine braking on slippery
road surfaces or at high speeds:
Shifting down while driving on wet,
snowy, or frozen roads, or while
driving at high speeds causes sudden
engine braking, which is dangerous.
The sudden change in tire speed could
cause the tires to skid. This could lead
to loss of vehicle control and an
accident.
Keep your hands on the steering
wheel rim when using fingers on the
steering shift switches:
Putting your hands inside the rim of
the steering wheel when using the
steering shift switches is dangerous. If
the driver's air bag were to deploy in a
collision, your hands could be
impacted causing injury.
NOTE
When driving at high speeds, the
gear may not shift down.
During deceleration, the gear may
automatically shift down depending
on vehicle speed.
When depressing the accelerator
fully, the transmission will shift to a
lower gear, depending on vehicle
speed. However, the gears do not
kickdown while the DSC is turned
o ff.
▼ Second Gear Fixed Mode
When the selector lever is moved back
+ while the vehicle speed is about 10
km/h (6.2 mph) or less, the
transmission is set in the second gear
fixed mode. The gear is
fixed in second
while in this mode for easier
acceleration from a stop and driving on
slippery roads such as snow-covered
roads.
If the selector lever is moved back + or
forward – while in the second gear
fixed mode, the mode will be
canceled.

Shift up
The gear does not shift up while the vehi cle speed is lower than the speed limit.
Shift down
The gear does not shift down while th e vehicle speed exceeds the speed limit.
If the vehicle speed exceeds the speed limi t and the gear does not shift down, the
gear position indication flashes 2 times to notify the driver that the gear cannot be
shifted.
Kickdown
When the accelerator pedal is depressed fu lly while driving, the gear shifts down.
However, the gears do not kickdown while the DSC is turned o ff.
NOTE
The gear also shifts down using kickdown while in the second gear fixed mode.
Auto-shift down
The gear shifts down automatically depending on the vehicle speed during
deceleration.
NOTE
If the vehicle comes to a stop while in the second gear fixed mode, the gear remains
in second.
