Automatic Transaxle Controls
Lock-release button
Indicates the shift lever can be shifted freely into any position.
Indicates that you must hold in the lock-release button 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 ge ar 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 4-32).

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 position.
The ignition cannot be switched to OFF
if the selector lever is not in P position.
▼ 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-wr apped 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 4-21.
The selector lever must be in P or N
position 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 position
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 3-42).
N (Neutral)
In N, the wheels and transaxle are not
locked. The vehicle will roll freely even
When Driving
Automatic Transaxle

CX-3_8JL1-EA-20G_Edition1_old 2020-5-22 15:31:00

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 position to prevent the
vehicle from moving unexpectedly.
D (Drive)
D is the normal driving position. From a
stop, the transaxle wi ll 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 4-32.
▼ 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/ve hicle 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.
