NOTE
If the engine is stopped with the i-stop
function stopped, the i-stop function
becomes operational again when the
engine is started the next time.
▼Vehicle Roll Prevention Function
Vehicles with the i-
stop function are
equipped with a vehicle roll prevention
function. This function prevents the
vehicle from rolling, such as when
releasing the brake pedal while on a
slope under the following conditions:
While engine idling is stopped
(prevents the vehicle from rolling
back)
When the engine restarts after
releasing the brake pedal (prevents
the vehicle's sudden movement due
to vehicle creep), sudden movement
of the vehicle is prevented by
controlling the brakes.
1. Release foot from brake pedal
2. Vehicle brake force maintained
3. Engine restarted

WARNING
Do not rely completely on the vehicle
roll prevention function.
The vehicle roll prevention function
is a supplementary function which
operates for a maximum of 2
seconds after releasing the brake
pedal and accelerating the vehicle
from an engine idling stop condition.
Over reliance on the system may
result in an unexpected accident if
the vehicle were to suddenly
accelerate. Before starting to drive
the vehicle, always confirm the safety
of the surroundings and operate the
selector lever, brake pedal, and
accelerator pedal appropriately.
Note that the vehicle may move
suddenly depending on the vehicle's
load or if it is towing something.
 Note that the vehicle may move
suddenly after the vehicle roll
prevention function is released while
the vehicle is under the following
conditions:
 The selector lever is in the N
position.
 If the selector lever is shifted to the
N position and the brake pedal is
released while the i-stop function
is operating, the brake force is
gradually released. To accelerate
the vehicle, release the brake pedal
after the engine restarts and shift
the selector lever to a position
other than the N position.
NOTE
When the vehicle is stopped on a
steep grade, the vehicle roll
prevention function does not
operate because engine idling is not
stopped.
The brake pedal response may
change, sound may occur from the
brakes, or the brake pedal could
vibrate from the operation of the
vehicle roll prevention function.
However, this does not indicate a
malfunction.
▼ i-stop Warning Light (Amber)/

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 4-40.
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
3-53).
NOTE
(With parking sensor system)
When the selector lever is shifted to
the R position with the ignition
switched ON, the parking sensor
system is activated and a beep sound is
heard.
Refer to Parking Sensor System on page
4-231.
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.

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 give s better acceleration when you need more
speed.

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

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 th
e 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 assist. In addition, the ISG provides quiet
engine restarting after the engine is st opped by the i-stop function (idling stop).
