NOTE
The Sport AT has an option that is not included in the traditional automatic transax\
le 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, confirm you have not accidentally
slipped into manual shift mode (page
4-35).

When Driving
Automatic Transaxle
Transaxle Ranges
 The shift position indicator light 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.
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
3-48).
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.
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 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.
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.

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 transaxle will shift to a lower gear,
depending on vehicle speed. However,
the gears do not kickdown while the
DSC is turned off.
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 transaxle 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.

Recommendations for Shifting
Upshifting
For normal acceleration and cruising, Mazda recommends these shift point\
s:
(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 and prolong\
s brake life.

Driving Tips
WARNING
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 grades 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.

Switches and Controls
*Some models.
Auto-light control*
When the headlight switch is in the position and the ignition is switched ON, the light
sensor senses the surrounding lightness or darkness and automatically tu\
rns the headlights
and other exterior lights on or off.
CAUTION
 Do not shade the light sensor by adhering a sticker or a label on the windshield. Otherwise
the light sensor will not operate correctly.
 The light sensor also works as a rain sensor for the auto-wiper control. Keep hands and
scrapers clear of the windshield when the wiper lever is in the position and the
ignition is switched ON as fingers could be pinched or the wipers and wiper blades could be
damaged when the wipers activate automatically. If you are going to clean the windshield,
be sure the wipers are turned off completely when it is particularly tempting to leave the
engine running. This is particularly important when clearing ice and snow.
NOTE
 The headlights and other exterior lights may not turn off immediately ev\
en if the
surrounding area becomes well-lit because the light sensor determines that it is night\

time if the surrounding area is continuously dark for several minutes such as inside long
tunnels, traffic jams inside tunnels, or in indoor parking lots.
In this case, the lights turn off if the light switch is turned to the position. The sensitivity of the auto-light control may be changed.
Refer to Personalization Features on page 9-12.
