Manual Transaxle Shift Pattern
5-speed transaxle
6-speed transaxleNeutral position
Neutral position
The vehicle is equipped with either a
5-speed or 6-speed manual transaxle. The
shift pattern for each is shown above.
Depress the clutch pedal all the way down
while shifting; then release it slowly.(5-speed transaxle)
A safety feature prevents accidental
shifting from 5 to R (reverse). The shift
lever must be put in neutral before being
shifted to R.
(6-speed transaxle)
Vehicles with 6-speed transaxle are
equipped with a device to prevent shifting
to R (reverse) by mistake. Push the shift
lever downward and shift to R.
WARNING
Do not use sudden 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 tyre speed could
cause the tyres to skid. This could
lead to loss of vehicle control and an
accident.
Be sure to leave the shift lever in 1 or
R position and set the parking brake
when leaving the vehicle unattended:
Otherwise the vehicle could move and
cause an accident.

*Some models.4–48
When Driving
Transaxle
CAUTION

 Keep your foot off the clutch pedal
except when shifting gears. Also, do
not use the clutch to hold the vehicle
on an upgrade. Riding the clutch
will cause needless clutch wear and
damage.
  Do not apply any excessive lateral
force to the shift lever when
changing from 5th to 4th gear. This
could lead to the accidental selection
of 2nd gear, which can result in
damage to the transaxle.
  Make sure the vehicle comes to a
complete stop before shifting to R.
Shifting to R while the vehicle is still
moving may damage the transaxle.
NOTE
  For vehicles with type C instrument
cluster*1
 If the engine speed is about to exceed
the permissible engine speed, the
buzzer sounds.
 Refer to Over Rev. Buzzer on page
7-53 .
 To determine which instrument
cluster is equipped on your Mazda,
Refer to Meters and Gauges on page
4-24 .
  If shifting to R is diffi cult, shift back
into neutral, release the clutch pedal,
and try again.
NOTE
  (With i-stop function)  If the engine has stopped due to
stalling, it can be restarted by
depressing the clutch pedal within 3
seconds of the engine stopping.
 The engine cannot be restarted even
if the clutch pedal is depressed under
the following conditions:

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 aware 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, confi rm you have not
accidentally slipped into manual shift mode (page 4-53 ).

 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.
WARNING
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 3-56 ).
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.
WARNING
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
vehicle:
Shifting into N while driving is
dangerous. Engine braking cannot be
applied when decelerating which could
lead to an accident or serious injury.

*Some models.4–52
When Driving
Transaxle
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 4-gear (4-speed transaxle
model)/6-gear (6-speed transaxle model)
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 4-53 .
Active Adaptive Shift (AAS) *
Active Adaptive Shift (AAS)
automatically controls the transaxle shift
points to best suit the road conditions
and driver input. This improves driving
feel. The transaxle may switch 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.
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 switched off,
the selector lever cannot be shifted
from P.
  The ignition cannot be switched to
OFF if the selector lever is not in P.

3. Press and hold the lock-release button.
4. Move the selector lever.
5. Take the vehicle to an expert repairer,
we recommend an Authorised Mazda
Repairer to have the system checked.
Manual Shift Mode
The manual shift mode gives you the feel
of driving a manual transaxle vehicle by
allowing you to operate the selector lever
manually. This allows you to control
engine rpm and torque to the drive wheels
much like a manual transaxle when more
control is desired.
To change to manual shift mode, shift the
lever from D to M.
NOTE
Changing to manual shift mode while
driving will not damage the transaxle.
To return to automatic shift mode, shift the
lever from M to D.
NOTE
  If you change to manual shift mode
when the vehicle is stopped, the gear
will shift to M1.
  (6-speed transaxle model)  If you change to manual shift mode
without depressing the accelerator
pedal when driving in D range, 5th
gear/6th gear, the gear will shift to
M4/M5.

the driver's air bag were to deploy in a
collision, your hands could be impacted
causing injury.
NOTE
  When driving slowly, the gears may
not shift up.
  In manual shift mode, do not run the
engine with the tachometer needle
in the RED ZONE. When the engine
rpm is high, a gear may shift up
automatically to protect the engine.
NOTE
  When depressing the accelerator
fully, the transaxle will shift to a
lower gear, depending on vehicle
speed.
  The steering shift switch can be used
temporarily even if the selector lever
is in the D position while driving. In
addition, it returns to automatic shift
mode when the UP switch (
)
is pulled rearward for a suffi cient
amount of time.

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 transaxle will shift to a
lower gear, depending on vehicle
speed.
Second gear fi xed mode
When the selector lever is moved back
while the vehicle speed is about 10 km/h
(6.2 mph) or less, the transaxle is set in the
second gear fi xed mode. The gear is fi xed
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 fi xed
mode, the mode will be cancelled.
