When Driving
ABS/TCS/DSC
Traction Control System
(TCS)
The Traction Control System (TCS)
enhances traction and safety by controlling
engine torque and braking. When the TCS
detects driving wheel slippage, it lowers
engine torque and operates the brakes to
prevent loss of traction.
This means that on a slick surface, the
engine adjusts automatically to provide
optimum power to the drive wheels,
limiting wheel spin and loss of traction.
The warning light turns on when the
system has a malfunction.
Refer to Warning Lights on page 4-21 .
WARNING
Do not rely on the Traction Control
System (TCS) as a substitute for safe
driving: The Traction Control System ( TCS)
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.

Use snow tires or tire chains and drive at
reduced speeds when roads are covered
with ice and/or snow: Driving without proper traction devices
on snow and/or ice-covered roads
is dangerous. The Traction Control
System ( TCS) alone cannot provide
adequate traction and you could still
have an accident.
NOTE
To turn off the TCS, press the DSC OFF
switch (page 4-81 ).
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 fl ashes.
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.
NOTE
 y  In addition to the indicator light
fl ashing, a slight lugging sound will
come from the engine. This indicates
that the TCS/DSC is operating properly.
 y On slippery surfaces, such as fresh
snow, it will be impossible to achieve
high rpm when the TCS is on.

When Driving
ABS/TCS/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 4-78 ) and TCS (page
4-79 ).
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 Warning Lights on page 4-21 .
WARNING
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.

When Driving
i-ELOOP
i-ELOOP *
On conventional vehicles, the kinetic energy that is generated when the vehicle is
decelerated by applying the brakes or during engine braking ends up bein\
g discarded as
heat. By utilizing this discarded kinetic energy to generate electricity and use it to power the
vehicle's electrical devices and accessories such as the A/C and audio, fuel consumption can
be reduced. Mazda's system for generating electricity from this kinetic \
energy is called the
Regenerative Braking System (i-ELOOP).

When Driving
Power Steering
Power Steering
 y 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.
 y The warning light notifi es the driver
of system abnormalities and operation
conditions.
 In addition, the buzzer may also activate depending on the system abnormality or
operation condition.
 Refer to Warning Lights on page 4-21 . Refer to Power Steering Warning Buzzer on page 7-38 .
CAUTION
Never hold the steering wheel to the
extreme left or right for more than 5
seconds with the engine running. This
could damage the power steering
system.

When Driving
Mazda Radar Cruise Control (MRCC)
 y In the following cases, the warnings may not activate even if your vehic\
le starts closing in
on the vehicle ahead.
 y You are driving at the same speed as the vehicle ahead. y Directly after the Mazda Radar Cruise Control (MRCC) system has been set. y When the accelerator pedal is depressed or directly after the accelerator pedal is
released.
 y Another vehicle cuts into the driving lane.
 y The following are not detected as physical objects.
 y Vehicles approaching in the opposite direction y Pedestrians y Stationary objects (stopped vehicles, obstructions)
 y If a vehicle ahead is traveling at an extremely low speed, the system may not detect it
correctly.
 y During headway control travel, do not set the system on two-wheeled vehicles such as
motorcycles and bicycles.
 y Do not use the Mazda Radar Cruise Control (MRCC) system under conditions in which
the close proximity warnings are frequently activated.
 y 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.
 y While the Mazda Radar Cruise Control (MRCC) system is in use, it does not cancel even
if the selector lever (automatic transaxle)/shift lever (manual trans\
axle) is operated and
any intended engine braking will not occur. If deceleration is required, lower the vehicle
speed setting or depress the brake pedal.
 y The brake lights are illuminated while the Mazda Radar Cruise Control (MRCC)
automatic braking is operating, however, they may not be illuminated while the vehicle is
on a down slope at the set vehicle speed or traveling at a constant spee\
d and following a
vehicle ahead.
 y The Mazda Radar Cruise Control (MRCC) warning light (amber) fl ashes when the system
has a malfunction.

When Driving
Tire Pressure Monitoring System
Tire Pressure Monitoring System *
The Tire Pressure Monitoring System (TPMS) monitors the air pressure of all\
four tires. If
the air pressure of one or more tires is too low, the system warns the driver by indicating the
tire pressure monitoring system warning light in the instrument cluster \
and operating a beep
sound. The system monitors the tire pressures indirectly using the data sent fr\
om the ABS
wheel speed sensors.
To allow the system to operate correctly, the system needs to be initialized with the specifi ed
tire pressure (value on the tire pressure label). Follow the procedure\
and perform the
initialization.
Refer to Tire Pressure Monitoring System Initialization on page 4-106 .
The warning light fl ashes when the system has a malfunction.
