Dynamic Stability Control(DSC)
▼Dynamic Stability Control (DSC)
The Dynamic Stability Control (DSC)
automatically controls braking and engine
torque in conjunction with systems such as
ABS and TCS to help control side slip
when driving on slippery surfaces, or
during sudden or evasive maneuvering,
enhancing vehicle safety.

Refer to ABS (page 4
-75) and TCS (page
4-76).

DSC operation is possible at speeds
greater than 20 km/h (12 mph).

The warning light turns on when the
system has a malfunction.
Refer to TCS/DSC Indication/Indicator
Light (Turns on) on page 7-32.
WA R N I N G
Do not rely on the Dynamic Stability
Control as a substitute for safe driving:
The Dynamic Stability Control (DSC)
cannot compensate for unsafe and reckless
driving, excessive speed, tailgating
(following another vehicle too closely), and
hydroplaning (reduced tire friction and
road contact because of water on the road
surface). You can still have an accident.
CAUTION
 The DSC may not operate correctly
unless the following are observed:
 Use tires of the correct size
specified for
your Mazda on all 4 wheels.
 Use tires of the same manufacturer,
brand and tread pattern on all 4
wheels.
 Do not mix worn tires.
 The DSC may not operate correctly when
tire chains are used or a temporary spare
tire is installed because the tire diameter
changes.
NOTE
If there is a problem with the DSC, the Hill
Launch Assist (HLA) may not operate.
Refer to Hill Launch Assist (HLA) on page
4-73.
▼ TCS/DSC Indicator Light
This indicator light stays on for a few
seconds when the ignition is switched ON.
If the TCS or DSC
is operating, the
indicator light flashes.

If the light stays on, the TCS, DSC or the
brake assist system may have a
malfunction and they may not operate
correctly. Take your vehicle to an
Authorized Mazda Dealer.

▼DSC OFF Indicator Light
This indicator light
stays on for a few
seconds when the ignition is switched ON.
It also illuminates when the DSC OFF
switch is pressed and TCS/DSC is
switched off.
Refer to DSC OFF Switch on page 4-78.

If the light remains illuminated and the
TCS/DSC is not switched off, take your
vehicle to an Authorized Mazda Dealer.
The DSC may have a malfunction.
▼ DSC OFF Switch
Press the DSC OFF switch to turn off the
TCS/DSC. The DSC OFF indicator light
in the instrument cluster and the DSC OFF
switch indicator lig
ht will illuminate.
1. DSC OFF switch indicator light

Press the switch again to turn the
TCS/DSC back on. The DSC OFF
indicator light and the DSC OFF switch
indicator light will turn off.
NOTE
When DSC is on and you attempt to free
the vehicle when it is stuck, or drive it
out of freshly fallen snow, the TCS (part
of the DSC system) will activate.
Depressing the accelerator will not
increase engine power and freeing the
vehicle may be difficult. When this
happens, turn off the TCS/DSC.
If the TCS/DSC is off when the engine is
turned off, it aut omatically activates
when the ignition is switched ON.
Leaving the TCS/DSC on will provide
the best traction.
If the DSC OFF switch is pressed and
held for 10 seconds or more, the DSC
OFF switch malfunction detection
function operates and the DSC system
activates automatically. The DSC OFF
indicator light turns off while the DSC
system is operative.
(Vehicles with Smart Brake Support
(SBS))
If the Smart Brake Support (SBS)
operates with the TCS/DSC turned off,
the TCS/DSC becomes operational
automatically.

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.
Traffic Jam Assist (TJA)* is operating.
Steering wheel is being operated
abruptly
▼Drive Selection Switch
Press the drive sele
ction switch forward
(SPORT) to select the sport mode.
Pull the drive selecti on 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.
Traffic Jam Assist (TJA) is set.
Depending on the driving conditions
when sport mode is selected, the vehicle
may perform shift-down or slightly
accelerate.

i-ACTIV AWD Operation*
▼i-ACTIV AWD Operation
AWD provides excellent drivability on
snow-covered and ice-packed roads, sand
and mud, as well as on steep slopes and
other slippery surfaces.
A system malfunction or operation
conditions are indicated by a warning.
Refer to Contact a
n Authorized Mazda
Dealer and AWD Warning Indication/
Warning Light on page 7-31.
WA R N I N G
Never spin a wheel that is off the ground:
Spinning a wheel that is off the ground as a
result of the vehicle being stuck or in a
ditch is dangerous. The drive assembly
could be seriously damaged which could
lead to an accident or could even lead to
overheating, oil leakage, and a fire.
▼ AWD Driving
This vehicle has not been designed for the
purpose of off-road driving or rallies. Do
not attempt to drive over uneven or rocky
surfaces, or across rivers.
Although this vehicle is equipped with
AWD, acceleration, steering and braking
operations should be conducted in the
same manner as with a non-AWD vehicle,
with the emphasis placed on safe driving.
▼Tires and Tire Chains
The condition of the tires plays a large role
in the performance of the vehicle.
Moreover, to prevent adverse effects to the
drive assembly, please note the following:
Tires
When replacing tires, always replace all
front and rear tires at the same time.
All tires must be of the same size,
manufacture, brand and tread pattern.
Pay particular attention when equipping
snow or other types of winter tires.
Do not mix tread-worn tires with normal
tires.
Inspect tire inflation pressures at the
specified periods adjust to the specified
pressures.
NOTE
Check the tire inflation pressure label
attached to driver's door frame for the
correct tire inflation pressure.
Make sure to equip the vehicle with
genuine wheels of the specified size, on
all wheels. With AWD, the system is
calibrated for all 4 wheels being of the
same dimensions.
Tire chains
Install tire chains to the front tires.
Do not use tire chains on the rear
wheels.
Do not drive the vehicle faster than 30
km/h (19 mph) with the tire chains
installed.
Do not drive the vehicle with tire chains
on road conditions other than snow or
ice.
▼ To w i n g
If the vehicle requires towing, have it
towed with all 4 wheels completely off the
ground.
Refer to Towing Description on page
7-23.

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 feel
s stiffer than usual
during normal driving or the steering
vibrates, consult an Authorized Mazda
Dealer.
The warning indication notifies the
driver of system abnormalities and
operation conditions.

i-ACTIVSENSE*
▼i-ACTIVSENSE
i-ACTIVSENSE is a collective term
covering a series of advanced safety and
driver support systems which make use of
cameras and sensors. T
he systems consist
of active safety and pre-crash safety
systems.
These systems are designed to assist the
driver in safer driving by reducing the load
on the driver and helping to avert
collisions or reduce their severity.
However, because each system has its
limitations, always dri ve carefully and do
not rely solely on the systems.
