When Driving
Brake
Brake System
Foot Brake
This vehicle has power-assisted brakes
that adjust automatically through normal
use.
Should power-assist fail, you can stop by
applying greater force than normal to the
brake pedal. But the distance required to
stop will be greater than usual.
WARNING
Do not coast with the engine stalled or
turned off, find a safe place to stop:
Coasting with the engine stalled or
turned off is dangerous. Braking will
require more effort, and the brake's
power-assist could be depleted if
you pump the brake. This will cause
longer stopping distances or even an
accident.
Shift to a lower gear when going down
steep hills:
Driving with your foot continuously on
the brake pedal or steadily applying
the brakes for long distances is
dangerous. This causes overheated
brakes, resulting in longer stopping
distances or even total brake failure.
This could cause loss of vehicle
control and a serious accident. Avoid
continuous application of the brakes.
Dry off brakes that have become
wet by driving slowly, releasing the
accelerator pedal and lightly applying
the brakes several times until the brake
performance returns to normal:
Driving with wet brakes is dangerous.
Increased stopping distance or the
vehicle pulling to one side when
braking could result in a serious
accident. Light braking will indicate
whether the brakes have been affected.
CAUTION
 Do not drive with your foot held on the
clutch pedal or brake pedal, or hold
the clutch pedal depressed halfway
unnecessarily. Doing so could result in
the following:
 The clutch and brake parts will wear
out more quickly. The brakes can overheat and
adversely affect brake performance.
 Always depress the brake pedal with
the right foot. Applying the brakes with
the unaccustomed left foot could slow
your reaction time to an emergency
situation resulting in insufficient braking
operation.

 Wear shoes appropriate for driving in
order to avoid your shoe contacting
the brake pedal when depressing the
accelerator pedal.

4–55
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 4-16.
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
 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. 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.

4–56
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 4-16.
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 4-58).
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.

4–57
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 4-55) and TCS
(page 4-56).
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 4-16.
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
 The DSC may not operate correctly
unless the following are observed:
 Use tires of the correct size specified
for your Mazda on all four wheels. Use tires of the same manufacturer,
brand and tread pattern on all four
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
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.

When Driving
ABS/TCS/DSC
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 4-58.
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 will illuminate.
Press the switch again 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 turns off while the DSC
system is operative.

When Driving
Drive Selection
*Some models.
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
 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. Steering wheel is being operated abruptly

When Driving
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 feels stiffer than usual
during normal driving or the steering
vibrates, consult an Authorized Mazda
Dealer. The warning light notifies the driver
of system abnormalities and operation
conditions.
Refer to Warning Lights on page
4-16.
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
Cruise Control
To Decrease Cruising Speed
Press the SET/ switch and hold it. The
vehicle will gradually slow.
Release the switch at the desired speed.
Press the SET/ switch and release it
immediately to adjust the preset speed.
Multiple operations will decrease the
preset speed according to the number of
times it is operated.
Decreasing speed with a single SET/
switch operation
Meter display for vehicle speed indicated
in km/h: 1 km/h (0.6 mph)
Meter display for vehicle speed indicated
in mph: 1 mph (1.6 km/h)
To Resume Cruising Speed at
More Than 25 km/h (16 mph)
If some other method besides the OFF/
CANCEL switch was used to cancel
cruising speed (such as applying the brake
pedal) and the system is still activated, the
most recent set speed will automatically
resume when the RESUME/ switch is
pressed.
If vehicle speed is below 25 km/h (16
mph), increase the vehicle speed up to 25
km/h (16 mph) or more and press the
RESUME/ switch.
To Temporarily Cancel
To temporarily cancel the system, use one
of these methods:
 Slightly depress the brake pedal. (Manual transmission)
Depress the clutch pedal. Press the OFF/CANCEL switch.
If the RESUME/ switch is pressed when
the vehicle speed is 25 km/h (16 mph) or
higher, the system reverts to the previously
set speed.
NOTE
 If any of the following conditions occur,
the cruise control system is temporarily
canceled.
 The parking brake is applied. (Automatic transmission)
The selector lever is in the P or N
position. (Manual transmission)
The shift lever is in the neutral
position.
 When the cruise control system is
temporarily canceled by even one of the
applicable cancel conditions, the speed
cannot be re-set. (Automatic transmission)
The cruise control cannot be cancelled
while driving in manual mode (selector
lever shifted from D to M position).
Therefore, engine braking will not be
applied even if the transaxle is shifted
down to a lower gear. If deceleration is
required, lower the set speed or depress
the brake pedal.
To Deactivate
When a cruising speed has been set
(cruise set indicator light (green) turns
on)
Long-press the OFF/CANCEL switch or
press the OFF/CANCEL switch 2 times.
When a cruising speed has not been set
(cruise main indicator light (amber)
turns on)
Press the OFF/CANCEL switch.

Climate Control System
Operating Tips
 Operate the climate control system with
the engine running. To prevent the battery from being
discharged, do not leave the fan control
dial on for a long period of time with the
ignition switched ON when the engine is
not running. Clear all obstructions such as leaves,
snow and ice from the hood and the air
inlet in the cowl grille to improve the
system efficiency. Use the climate control system to defog
the windows and dehumidify the air. The recirculate mode should be used
when driving through tunnels or while in
a traffic jam, or when you would like to
shut off outside air for quick cooling of
the interior. Use the outside air position for
ventilation or windshield defrosting. If the vehicle has been parked in direct
sunlight during hot weather, open the
windows to let warm air escape, then
run the climate control system.
 Run the air conditioner about 10 minutes
at least once a month to keep internal
parts lubricated.
 Have the air conditioner checked before
the weather gets hot. Lack of refrigerant
may make the air conditioner less
efficient.
The refrigerant specifications are
indicated on a label attached to the
inside of the engine compartment. Check
the label before refilling the refrigerant.
If the wrong type of refrigerant is used,
it could result in a serious malfunction
of the air conditioner.
For details, consult an Authorized
Mazda Dealer.
