CAUTION
 Do not use sharp instruments or window
cleaners with abrasives to clean the
inside of the rear window surface. They
may damage the defogger grid inside the
window.
 Before opening the convertible top, make
sure the rear window defogger switch is
turned off. Otherwise the heat generated
from the defogger could damage the
convertible top and the internal material.
NOTE
This defogger is not designed for
melting snow. If there is an
accumulation of snow on the rear
window, remove it before using the
defogger.

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 Contact Authorized Mazda
Dealer and Have Vehicle Inspected on
page 7-36.
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 co uld still have an
accident.
NOTE
To turn off the TCS, press the DSC OFF
switch (page 4-69).
▼ 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.
NOTE
In addition to the indicator light
flashing, a slight lugging sound will
come from the engine. This indicates
that the TCS/DSC is operating properly.
On slippery surfaces, such as fresh
snow, it will be impossible to achieve
high rpm when the TCS is on.

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 4-66) and TCS (page
4-67).

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 Contact Authorized Mazda
Dealer and Have Vehicle Inspected on
page 7-36.

Do not rely on the Dynamic Stability

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.
▼ TCS/DSC Indicator Light
This indicator light stays on for a few

▼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 4-69.

If the light remains i lluminated 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 sw
itch to turn off the
TCS/DSC. The DSC OFF indicator light
in the instrument cluster will illuminate.
Press the switch a gain to turn the
TCS/DSC back on. The DSC OFF
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 automatically 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 turn s off while the DSC
system is operative.

Drive Selection*
Drive selection is a system to switch the vehicle's drive mode. When the sport mode is
selected, the vehicle's response against accelerator operation is enhanced. This provides
additional quick acceleration which may be needed to safely mak e maneuvers such as lane
changes, merging onto freeways, or passing other vehicles.
CAUTION
Do not use the sport mode when driving on slip pery roads such as wet or snow-covered roads.
It may cause tire slipping.
NOTE
When sport mode is selected, driving at higher engine speeds may increase fuel
consumption. Mazda recommends that you cancel sport mode for normal driving.
Drive mode cannot be switched in the following conditions:
ABS/TCS/DSC is operating
Cruise control is operating.
Steering wheel is being operated abruptly

automatically and the LDWS warning
light in the instrument cluster turns on.
The temperature inside the camera is
high or low.
The windshield around the camera is
foggy.
The windshield around the camera is
blocked by an obstruction, causing poor
forward visibility.
The LDWS is enabled automatically when
the operation conditions are met, and the
LDWS warning light turns off.
Auto cancel warning
When the following operations are
performed, the LDWS determines that the
driver intends to make a lane change and
the LDWS warning is canceled
automatically. The LDWS is enabled
automatically after the driver performs the
operation.
The steering wheel is operated abruptly.
The brake pedal is depressed abruptly.
The accelerator pedal is depressed
abruptly.
The turn signal lever is operated (after
the turn signal lever is returned, the
LDWS may not operate for about 3
seconds which is the period of time
required to make a lane correction).
NOTE
After about 30 seconds have elapsed with
the turn signal lever left operating, the
LDWS warning may operate if the vehicle
is close to a white or yellow line.
▼ Canceling the System
Press the LDWS OFF sw
itch to cancel the
LDWS. The LDWS OFF indicator light
turns on.
Vehicle lane display (vehicles with
multi-information display)
The vehicle lane lines are no longer
indicated in the multi -information display

The temperature near the radar sensors (rear) becomes extremely hot due to driving for
long periods on slopes during the summer.
The battery voltage has decreased.
Under the following conditions, the radar sensors (rear) cannot detect target objects or it
may be difficult to detect them.
A vehicle is in the detection area at the rear in an adjacent driving lane but it does not

Warning Beep
The BSM or Rear Cross Traffic Al ert (RCTA) system notifies the driver of the presence of
vehicles in adjacent lanes to the rear of your vehicle using th e BSM warning lights and the
warning beep while the s ystems are operational.
BSM warning lights
The BSM warning lights are equi pped on the left and right door mirrors. The warning lights
turn on when a vehicle approaching from the rear in an adjacent lane is detected.
When the ignition is switched ON, the malfunction warning light turns on momentarily and
then turns off after a few seconds.
Forward driving (BSM system operation)
The BSM system detects vehicles approaching from the rear and t urns on the BSM warning
lights equipped on the door mirrors according to the conditions . Additionally, while a BSM
warning light is illuminated, if the turn signal lever is operated to signal a turn in the
direction in which the BSM warni ng light is illuminated, the BSM warning light flashes.
Reverse driving (Rear Cross Traf fic Alert (RCTA) system operation)
The Rear Cross Traffic Alert (RCTA) system detects vehicles app roaching from the left and
right of your vehicle and flashes the BSM warning lights.
Function for cancelling illumination dimmer
If the BSM warning lights turn on when the parking lights are turned on, the brightness of
the BSM warning lights is dimmed.
If the BSM warning lights are d ifficult to see due to glare from surrounding brightness when
traveling on snow-covered roads or under foggy conditions, pres s the dimmer cancellation
button to cancel the dimmer and increase the brightness of BSM warning lights when they
turn on.
