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).

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).

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.

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.
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.
▼Indicators

NOTE
When driving slowly, the gears may not
shift up.
Do not drive the vehicle with the
tachometer needle in the RED ZONE
while in manual shift mode. In addition,
manual shift mode switches to automatic
shift mode while the accelerator pedal is
completely depressed.
This function is canceled while the DSC
is turned off. However, if the vehicle is
continuously driven at a high rpm, the
gears may automatically shift up to
protect the engine.
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 sufficient amount
of time.
▼ Manually Shifting Down
You can shift gears down by operating the
selector lever or the steering shift
switches
*.
M6 → M5 → M4 → M3 → M2→ M1
Using selector lever
To shift down to a lower gear, tap the
selector lever forward
once.

Using steering shift switch*
To shift down to a l ower gear with the
steering shift switches, pull the DOWN
switch
toward you once with your
fingers.

DOWN switch
WA R N I N G
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.

▼Recommendations for Shifting
Upshifting
For normal acceleration and cruising, Mazda recommends these shift points:
(U.S.A. and Canada)
Gear
Vehicle speed*1
M1 to M224 km/h (15 mph)
M2 to M3 40 km/h (25 mph)
M3 to M4 65 km/h (40 mph)
M4 to M5 73 km/h (45 mph)
M5 to M6 81 km/h (50 mph)
*1 Always observe local speed limit regulations.
Downshifting
When you must slow down in heavy traffic or on a steep upgrade, downshift before the
engine starts to overwork. This gives better acceleration when you need more speed.

On a steep downgrade, downshifting helps maintain safe speed an d prolongs brake life.

Driving Tips
WA R N I N G
Do not let the vehicle move in a direction
opposite to the direction selected by the
selector lever:
Do not let the vehicle move backward with
the selector lever in a forward position, or
do not let the vehicle move forward with
the selector lever in the reverse position.
Otherwise, the engine may stop, causing
the loss of the power brake and power
steering functions, and make it difficult to
control the vehicle which could result in an
accident.
Passing
For extra power when passing another
vehicle or climbing steep grades, depress
the accelerator fully. The transaxle will
shift to a lower gear, depending on vehicle
speed.
NOTE
(Some models)
The accelerator pedal may initially feel
heavy as it is being depressed, then feel
lighter as it is depressed further. This
change in pedal force aids the engine
control system in determining how much
the accelerator pedal has been
depressed for performing kickdown, and
functions to control whether or not
kickdown should be performed.
While the selector lever is in the M
position and the DSC is turned off,
manual shift mode does not switch to
automatic shift mode even if the
accelerator pedal is completely
depressed. Operate the selector lever.
Climbing steep gra des from a stop
To climb a steep grade from a stopped
position:
1. Depress the brake pedal.
2. Shift to D or M1, depending on the load weight and grade steepness.
3. Release the brake pedal while gradually accelerating.
Descending steep grades
When descending a steep grade, shift to
lower gears, depending on load weight and
grade steepness. Descend slowly, using the
brakes only occasionally to prevent them
from overheating.
