Drive Selection*
▼Drive Selection
Drive selection is a system to switch
the vehicle's drive mode. When the
sport mode is selected, vehicle's
response against accelerator operation
is enhanced. This provides additional
quick acceleration which may be
needed to safely make maneuvers such
as lane changes, merging onto
freeways, or passing other vehicles.
CAUTION
Do not use the sport mode when
driving on slippery roads such as wet
or snow-covered roads. It may cause
tire slipping.
NOTE
When the sport mode is selected,
driving at higher engine speeds
increases and it may increase fuel
consumption. Mazda recommends
that you cancel the sport mode on
normal driving.
Drive mode cannot be switched in
the following conditions:
ABS/TCS/DSC is operatingCruise control* is operating.The Mazda Radar Cruise Control
with Stop & Go function (MRCC
with Stop & Go function) System
*
is operating.Tra ffi c
Jam Assist (TJA)* is
operating.
Steering wheel is being operated
abruptly
▼ Drive Selection Switch
Press the drive selection switch forward
(SPORT) to select the sport mode.
Pull the drive selection switch back
(OFF) to cancel the sport mode.

NOTE
In the following cases, the drive
selection is canceled.
The ignition is switched OFF.Cruise Control is set.Mazda Radar Cruise Control with
Stop & Go function (MRCC with
Stop & Go function) is set.
Tra ffi c
Jam Assist (TJA) is set.Depending on the driving conditions
when sport mode is selected, the
vehicle may perform shift-down or
slightly accelerate.

Power Steering
▼Power Steering
Power steering is only operable when
the engine is running. If the engine is
off
or if the power steering system is
inoperable, you can still steer, but it
requires more physical effort.
If the steering feels stiffer than usual
during normal driving or the steering
vibrates, consult an Authorized
Mazda Dealer.
The malfunction indication/indicator
light notifies the driver of system
abnormalities and operation
conditions.

If there is a structure on the road or
an object (such as a monorail) at a
low height off the ground in front of
the vehicle, the system may operate.
Therefore, do not use the MRCC.
Do not use the MRCC system under
conditions in which close proximity
warnings are frequently activated.
During headway control travel, the
system accelerates and decelerates
your vehicle in conjunction with the
speed of the vehicle ahead.
However, if it is necessary to
accelerate for a lane change or if the
vehicle ahead brakes suddenly
causing you to close in on the vehicle
rapidly, accelerate using the
accelerator pedal or decelerate using
the brake pedal depending on the
conditions.
While the MRCC system is in use, it
does not cancel even if the shift lever
is operated and any intended engine
braking will not occur. If deceleration
is required, lower the vehicle speed
setting or depress the brake pedal.
While braking by the MRCC control
is operating, you might hear an
operation sound, however, this does
not indicate a problem.
The brake lights turn on while
braking by the MRCC control is
operating, however, they may not
turn on while the vehicle is on a
down slope at the set vehicle speed
or traveling at a constant speed and
following a vehicle ahead.
Stop the headway control function to
switch the system to the cruise
control function.
Refer to the Settings section in the
Mazda Connect Owner's Manual.

Control with Stop & Go function (MRCC with
Stop & Go function) (Automatic
Transmission)
*
▼ Mazda Radar Cruise Control with
Stop & Go function (MRCC with
Stop & Go function)
The MRCC with Stop & Go function
system is designed to maintain
headway control
*1 with a vehicle
ahead according to your vehicle's
speed using a front radar sensor to
detect the distance to the vehicle
ahead and a preset vehicle speed
without you having to use the
accelerator or brake pedals.
*1 Headway Control: Control of the distance between your vehicle and
the vehicle ahead detected by the
Mazda Radar Cruise Control
(MRCC) system.
Additionally, if your vehicle starts
closing in on the vehicle ahead such as
if the vehicle ahead brakes suddenly, a
warning sound and a warning
indication in the display are activated
simultaneously to alert you to maintain
a sufficient distance between the
vehicles.
If the vehicle ahead stops while you are
following behind it, your vehicle will
stop and be held stopped
automatically (stop hold control), and
headway control will resume when you
resume driving the vehicle such as by
pressing the RES switch.
Also refer to the following before using
the MRCC with Stop & Go function.

Do not get out of the vehicle while
the stop hold control is operating:
Getting out of the vehicle while the
stop hold control is operating is
dangerous as the vehicle may move
unexpectedly and result in an accident.
Before getting out of the vehicle,
switch the MRCC with Stop & Go
function system off, shift the selector
lever to the P position, and apply the
parking brake.
CAUTION
If your vehicle is towed or you are
towing something, switch the MRCC
with Stop & Go function system off
to prevent an unexpected operation.
 Turn the system off when the vehicle
is running on a chassis roller.
NOTE
The MRCC with Stop & Go function
system does not detect the following
as physical objects.
Vehicles approaching in the
opposite direction
Pe de st ri a nsStationary objects (stopped
vehicles, obstructions)
If a vehicle ahead is traveling at an
extremely low speed, the system may
not detect it correctly.
If there is a structure on the road or
an object (such as a monorail) at a
low height off the ground in front of
the vehicle, the system may operate.
Therefore, do not use the MRCC
with Stop & Go function.
Do not use the MRCC with Stop &
Go function system under conditions
in which close proximity warnings
are frequently activated.
During headway control travel, the
system accelerates and decelerates
your vehicle in conjunction with the
speed of the vehicle ahead.
However, if it is necessary to
accelerate for a lane change or if the
vehicle ahead brakes suddenly
causing you to close in on the vehicle
rapidly, accelerate using the
accelerator pedal or decelerate using
the brake pedal depending on the
conditions.
While the MRCC with Stop & Go
function system is in use, it does not
cancel even if the selector lever is
operated and any intended engine
braking does not occur. If
deceleration is required, lower the
set speed or depress the brake
pedal.
While braking by the MRCC with
Stop & Go function control is
operating , you might hear an
operation sound, however, this does
not indicate a problem.
The brake lights turn on while
braking by the MRCC with Stop &
Go function control is operating,
however, they may not turn on while
the vehicle is on a down slope at the
set vehicle speed or traveling at a
constant speed and following a
vehicle ahead.
Stop the headway control function to
switch the system to the cruise
control function.
