possible.
Refer to Taking Action on page 7-32 .
NOTE
After refueling, it may require some time
for the indicator to stabilize. In addition,
the indicator may deviate while driving
on a slope or curve since the fuel moves
in the tank.
The display indicating a quarter or less
remaining fuel has more segments to
show the remaining fuel level in greater
detail.

on in the daytime, the dashboard
illumination does not dim.
NOTE
(With auto-light control)
When the ignition is switched ON in the
early evening or at dusk, the dashboard
illumination is dimmed for several
seconds until the light sensor detects the
brightness of the surrounding area,
however, the dimmer may cancel after
the brightness is detected.
When the position lights are turned on,
the position lights i ndicator light in the
instrument cluster turns on.
Refer to Headlights on page 4-43.
The brightness of the instrument cluster

▼Trip Computer and INFO Switch*
The following inform
ation can be selected
by pressing the INFO switch with the
ignition switched ON.
Distance-to-empty mode
Average fuel economy mode
Current fuel economy mode
Average vehicle speed
If you have any problems with your trip
computer, consult an Authorized Mazda
Dealer.
Distance-to-empty mode
This mode 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 sufficient 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 may 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 differ from
the amount indicated.
Average fuel economy mode
This mode displays the average fuel
economy by calculating the total fuel
consumption and the total traveled
distance since purchasing the vehicle,
re-connecting the battery after
disconnection, or rese tting the data. The
average fuel economy is calculated and
displayed every minute.

To clear the data being displayed, press the
INFO switch for more than 1.5 seconds.
After pressing the INFO switch, - - -
L/100 km (- - - mpg) w ill be displayed for
about 1 minute before the fuel economy is
recalculated and displayed.
Current fuel economy mode
This mode displays the current fuel
economy by calculating the amount of fuel
consumption and the distance traveled.

Current fuel economy will be calculated
and displayed every 2 seconds.

Automatic Transaxle Controls
Lock-release button
Indicates the selector lever can be shifted freely into any position.
Indicates that you must hold in the lock-release b utton to shift.
Indicates that you must depress the brake pedal and hold in the lock-release
button to shift (The ignition must be switched ON).
Various Lockouts:
NOTE
The Sport AT has an option that is not included in the traditional automatic transaxle that
gives the driver the option of selecting each gear instead of leaving it to the transaxle to
shift gears. Even if you intend to use the automatic transaxle functions as a traditional
automatic, you should also be aw are that you can inadvertently shift into manual shift mode
and an inappropriate gear may be retained as the vehicle speed increases. If you notice the
engine speed going higher or hear the engine racing, confirm you have not accidentally
slipped into manual shift mode (page 4-35).

Shift-Lock System
The shift-lock system prevents shifting out
of P unless the brake pedal is depressed.

To shift from P:
1. Depress and hold the brake pedal.
2. Start the engine.
3. Press and hold the lock-release button.
4. Move the selector lever.
NOTE
When the ignition is switched to ACC or
the ignition is switch ed off, the selector
lever cannot be shifted from P.
The ignition cannot be switched to OFF
if the selector lever is not in P.
▼ Shift-Lock Override
If the selector lever will not move from P
using the proper shift procedure, continue
to hold down the brake pedal.
1. Remove the shift-lock override cover
using a cloth-wrapped flat head
screwdriver.
2. Insert a screwdriver and push it down.
Cover
3. Press and hold the lock-release button.
4. Move the selector lever.
Take the vehicle to an Authorized Mazda
Dealer to have the system checked.
Transaxle Ranges
The shift position indication in the
instrument cluster illuminates. Refer to
Warning/Indicator Lights on page 4-23.
The selector lever must be in P or N to
operate the starter.
P (Park)
P locks the transaxle and prevents the
front wheels from rotating.
WA R N I N G
Always set the selector lever to P and set
the parking brake:
Only setting the selector lever to the P
position without using the parking brake to
hold the vehicle is dangerous. If P fails to
hold, the vehicle could move and cause an
accident.
CAUTION
 Shifting into P, N or R while the vehicle is
moving can damage your transaxle.
 Shifting into a driving gear or reverse
when the engine is running faster than
idle can damage the transaxle.
R (Reverse)
In position R, the vehicle moves only
backward. You must be at a complete stop
before shifting to or from R, except under
rare circumstances as explained in
Rocking the Vehicle (page 3-47).
When Driving
Automatic Transaxle
4-33
Mazda3_8GE4-EA-17F_Edition1 2017-4-7 11:59:21

N (Neutral)
In N, the wheels and transaxle are not
locked. The vehicle will roll freely even
on the slightest incline unless the parking
brake or brakes are on.
WA R N I N G
If the engine is running faster than idle, do
not shift from N or P into a driving gear:
It's dangerous to shift from N or P into a
driving gear when the engine is running
faster than idle. If this is done, the vehicle
could move suddenly, causing an accident
or serious injury.
Do not shift into N when driving the
vehic le:
Shifting into N while driving is dangerous.
Engine braking cannot be applied when
decelerating which could lead to an
accident or serious injury.
CAUTION
Do not shift into N when driving the
vehicle. Doing so can cause transaxle
damage.
NOTE
Apply the parking brake or depress the
brake pedal before moving the selector
lever from N to prevent the vehicle from
moving unexpectedly.
D (Drive)
D is the normal driving position. From a
stop, the transaxle will automatically shift
through a 6-gear sequence.
M (Manual)
M is the manual shift mode position.
Gears can be shifted up or down by
operating the selector lever. Refer to
Manual Shift Mode on page 4-35.
▼ Shift Position
Indication
The selector position is indicated when the
ignition is switched ON.
Gear position indication
In manual shift mode, the “M” of the shift
position indication illuminates and the
numeral for the selected gear is displayed.
▼ Active Adaptive Shift (AAS)
Active Adaptive
Shift (AAS)
automatically controls the transaxle shift
points to best suit the road conditions and
driver input. This im proves driving feel.
The transaxle may s witch to AAS mode
when driving up and down slopes,
cornering, driving at high elevations, or
depressing the accelerator pedal quickly
while the selector lever is in the D
position. Depending on the road and
driving conditions/vehicle operations, gear
shifting could be delayed or not occur,
however, this does not indicate a problem
because the AAS mode will maintain the
optimum gear position.
