When Driving
ABS/TCS/DSC
Antilock Brake System
(ABS)
The ABS control unit continuously
monitors the speed of each wheel. If
one wheel is about to lock up, the ABS
responds by automatically releasing and
reapplying that wheel's brake.
The driver will feel a slight vibration in
the brake pedal and may hear a chattering
noise from the brake system. This is
normal ABS system operation. Continue to
depress the brake pedal without pumping
the brakes.
The warning light turns on when the
system has a malfunction.
Refer to Warning Lights on page 4-21 .
WARNING
Do not rely on ABS as a substitute for
safe driving: The ABS cannot compensate for unsafe
and reckless driving, excessive speed,
tailgating (following another vehicle
too closely), driving on ice and snow,
and hydroplaning (reduced tire friction
and road contact because of water on
the road surface). You can still have an
accident.
NOTE
 y Braking distances may be longer on
loose surfaces (snow or gravel, for
example) which usually have a hard
foundation. A vehicle with a normal
braking system may require less
distance to stop under these conditions
because the tires will build up a wedge
of surface layer when the wheels skid.
 y The sound of the ABS operating may
be heard when starting the engine
or immediately after starting the
vehicle, however, it does not indicate a
malfunction.

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.

i-ELOOP Indicator Light/Control Status Display
The driver is notifi ed of the i-ELOOP
power generating status and the vehicle
conditions by the i-ELOOP indicator light
and the control status display.
i-ELOOP Indicator Light
Illuminated (vehicle without type B
audio)
The light turns on during power
generation.
Flashing
If the engine is started after the vehicle has
not been driven for a long period of time,
the i-ELOOP indicator light may fl ash.
Leave the engine idling and wait until the
indicator light turns off.
NOTE
 y  The beep will sound if the vehicle is
driven while the i-ELOOP indicator
light is fl ashing. In addition, if you
turn the steering wheel while the light
is fl ashing, it will feel heavier than
normal, but this does not indicate an
abnormality. Stop the vehicle in a safe
location with the engine running and do
not attempt to turn the steering wheel.
The steering operation will return to
normal after the i-ELOOP indicator
light stops fl ashing.
 y(Vehicles with type B audio) A notifi cation is displayed in the center
display and the i-ELOOP indicator light
fl ashes at the same time.
 Refer to Warning Message Indicated on Display on page 7-33 .
Control status display (vehicles with
type B audio)
The i-ELOOP power generating status is
displayed in the center display.
Refer to Control Status Display on page
4-86 .

When Driving
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 enhance\
d. This provides
additional quick acceleration which may be needed to safely make maneuve\
rs 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
 y When the sport mode is selected, driving at higher engine speeds increases and it may
increase fuel consumption. Mazda recommends to cancel the sport mode on normal
driving.
 y Drive mode cannot be switched in the following conditions:
 y ABS/TCS/DSC is operating y Steering wheel is being operated abruptly

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.

When Driving
Tire Pressure Monitoring System
Tire Pressure Monitoring System Initialization
In the following cases, system
initialization must be performed so that the
system operates normally.
 y  A tire pressure is adjusted. y Tire rotation is performed. y A tire or wheel is replaced. y The battery is replaced or completely
drained.
 y  The tire pressure monitoring system
warning light is illuminated.
Initialization method
1. Park the car in a safe place and fi rmly
apply the parking brake.
2. Let the tires cool, then adjust the tire pressure of all four (4) tires to the
specifi ed pressure indicated on the tire
pressure label located on the door jamb
of the driver's door (door open).
Refer to Tires on page 9-10 .
3. Switch the ignition ON.
4. While the vehicle is parked, press and hold the tire pressure monitoring
system set switch and verify that
the tire pressure monitoring system
warning light in the instrument cluster
fl ashes twice and a beep sound is heard
once.
CAUTION
If the system initialization is performed
without adjusting the tire pressure,
the system cannot detect the normal
tire pressure and it may not illuminate
the tire pressure monitoring system
warning light even if a tire pressure is
low, or it may illuminate the light even
if the pressures are normal.
The system initialization will not be
performed if the switch is pressed while
the vehicle is being driven.
