Tra n s m i s s i o n R a n ge s
▼Transmission Ranges
The shift position indication in the
instrument cluster illuminates.
Refer to Shift Position Indication on
page 4-44.
Shift the selector lever to the P or N
position to start the engine.
P (Park)
P locks the transmission and prevents
the front wheels from rotating.
WARNING
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
transmission.
 Shifting into a driving gear or reverse
when the engine is running faster
than idle can damage the
transmission.
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 transmission 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
transmission 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 transmission 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
4-44.
▼Shift Position Indication
1. 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 transmission
shift points to best suit the road
conditions and driver input. This
improves driving feel. The transmission
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
▼ Manual Shift Mode
The manual shift mode gives you the
feel of driving a manual transmission
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
transmission 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
transmission.
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.
To return to automatic shift mode, shift
the lever from M to D.

WARNING
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 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 or the Off-Road
Traction Assist is turned on.
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 (+/OFF)
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 lower gear with the
steering shift switches, pull the DOWN
switch (–) toward you once with your
fingers.

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 transmission will shift to a
lower gear, depending on vehicle
speed. However, the transmission
does not kickdown while the DSC is
turned off or the Off-Road Traction
Assist is operating.
▼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
transmission 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.

NOTE
If the vehicle comes to a stop while in the second gear fixed mode, the gear remains
in second.
▼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 ma intain safe speed and prolongs brake
life.

Driving Tips
▼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.
Pa s s i n g
For extra power when passing another
vehicle or climbing steep grades,
depress the accelerator fully. The
transmission will shift to a lower gear,
depending on vehicle speed.
NOTE
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.
The manual shift
mode does not
switch to automatic shift mode while
the DSC is turned off or the
Off-Road Traction Assist is turned on
when the selector lever is in the M
position. Shift 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.

M Hybrid*
▼M Hybrid
M Hybrid uses the Integrated Starter-Generator (ISG) with excellent power
generation efficiency to generate electricity from the kinetic energy generated when
the vehicle decelerates. The system uses the electrical power stored in the M Hybrid
battery, which is a large-capacity battery to
improve driveability and fuel economy by
reducing engine load and providing motor a ssist. In addition, the ISG provides quiet
engine restarting after the engine is stop ped by the i-stop function (idling stop).
