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 Indication/Warning
Lights on page 4-26 .
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.

N O T E
To turn off the TCS, press the DSC OFF
switch (page 4-68 ).

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 À 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.
N O T E
 


y In addition to the indicator light
À 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 4-65 ) and TCS
(page 4-66 ).

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 Indication/Warning
Lights on page 4-26 .
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.

CAUTION
 


¾ The DSC may not operate correctly
unless the following are observed:
 


¾ Use tires of the correct size specifi ed
for your Mazda on all four wheels.
 


¾ Use tires of the same manufacturer,
brand and tread pattern on all four
wheels.
 


¾ Do not mix worn tires. 



¾ The DSC may not operate correctly when
tire chains are used or a temporary spare
tire is installed because the tire diameter
changes.

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 À 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.

When Driving
i-ACTIVSENSE
*Some models.
Lane Departure Warning System (LDWS) *
The LDWS system noti¿ es the driver that the vehicle may be deviating from its lane.
The system detects the white or yellow lines on the traf¿ c lane using the Forward Sensing
Camera (FSC) and if it determines that the vehicle may be deviating from its lane, it noti¿ es
the driver by À ashing the LDWS warning light and activating the LDWS warning beep, and
by the multi-information display (vehicles with multi-information display).
Use the LDWS when you drive the vehicle on roads with white or yellow lines.
Refer to Forward Sensing Camera on page 4-95 .


Forward Sensing Camera
(FSC)

The warning light illuminates when the system has a malfunction.
Refer to Warning Indication/Warning Lights on page 4-26 .
WARNING
Do not use the LDWS under the following conditions:
The system may not operate adequately according to the actual driving conditions,
resulting in an accident.
 


¾ Driving on roads with tight curves.



¾ Driving under bad weather conditions (rain, fog, and snow).

The functions of the LDWS have limitations:
Always stay on course using the steering wheel and drive with care. The system is not
designed to compensate for a driver’s lack of caution and if you rely too much on the
LDWS it could lead to an accident. The driver is responsible for assuring lane changes and
other maneuvers. Always pay attention to the direction in which the vehicle is traveling
and the vehicle’s surroundings.

When Driving
i-ACTIVSENSE
CAUTION
Do not modify the suspension. If the vehicle height or the damping force of the
suspensions is changed, the LDWS may not operate correctly.

N O T E
 


y If your vehicle deviates from its traf¿ c lane, the LDWS operates (warning sound and
indicator light). Steer the vehicle adequately to drive the vehicle to the center of the lane.
 


y When the turn signal lever is operated for a lane change, the LDWS warning is
automatically canceled. The LDWS warning becomes operable when the turn signal lever
is returned and the system detects the white or yellow lines.
 


y If the steering wheel, accelerator pedal, or brake pedal is operated abruptly and the
vehicle moves close to a white or yellow line, the system determines that the driver is
making a lane change and the LDWS warning is automatically canceled.
 


y The LDWS may not operate during the period immediately after the vehicle has deviated
from its lane and the LDWS has operated, or the vehicle deviates from its lane repeatedly
within a short period of time.
 


y The LDWS does not operate if it does not detect the white or yellow lines of the traf¿ c
lane.
