Driving Tips
Except Mexico (18–inch wheel vehicle)
The vehicle is originally equipped with
all season radials designed to be used all
year around. In some extreme climates you
may find it necessary to replace them with
snow tires during the winter months to
further improve traction on snow and ice
covered roads.
Mexico (18–inch wheel vehicle)
The vehicle is originally equipped with
summer tires designed for optimum
traction on wet and dry roads. If your
vehicle is to be used on snow and ice
covered roads, Mazda recommends that
you replace the tires originally equipped
on your vehicle with snow tires during the
winter months.
WARNING
Use only the same size and type tires
(snow, radial, or non-radial) on all four
wheels:Using tires different in size or type is
dangerous. Your vehicle's handling
could be greatly affected and result in
an accident.
CAUTION
Check local regulations before using
studded tires.
Tire Chains
Check local regulations before using tire
chains.
CAUTION
 Chains may a ffect handling. Do not go faster than 50 km/h (30 mph)
or the chain manufacturer's
recommended limit, whichever is lower.
 Drive carefully and avoid bumps, holes,
and sharp turns. Avoid locked-wheel braking. Do not use chains on a temporary spare
tire; it may result in damage to the
vehicle and to the tire.
 Do not use chains on roads that are free
of snow or ice. The tires and chains could
be damaged.
 Chains may scr atch or chip aluminum
wheels.
NOTE
The tire pressure monitoring system may
not function correctly when using tire
chains.
Install the chains on the front tires only.
Do not use chains on the rear tires.
Please consult an Authorized Mazda
Dealer.
Installing the chains
1. If your vehicle is equipped with wheel
covers remove them, otherwise the
chain bands will scratch them.
2. Secure the chains on the front tires as
tightly as possible.
Always follow the chain manufacturer's
instructions.
3. Retighten the chains after driving
1/2—1 km (1/4—1/2 mile).

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
4-68) and TCS
(page
4-69).
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
4-24.
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.

WARNING
Do not rely completely on the Lane-keep Assist System (LAS) & Lane Departure
Warning System (LDWS):
 The Lane-keep Assist System (LAS) & Lane Departure Warning System (LDWS) is not an
automatic driving system. In addition, the system is not designed to compensate for a
driver's lack of caution, and over-reliance on the system could lead to an accident.
 The detection ability of the Lane-keep Assist System (LAS) & Lane Departure Warning
System (LDWS) is limited. Always stay on course using the steering wheel and drive
with care.
Do not use the Lane-keep Assist System (LAS) & Lane Departure Warning System
(LDWS) in the following cases: The system may not operate adequately according to the actual driving conditions,
resulting in an accident.
 Driving on roads with tight curves. Driving under bad weather conditions (rain, fog, and snow). Slippery roads such as ice or snow-bound roads. Roads with heav y traffic and insufficient distance between vehicles. Roads with no whit e (yellow) lane lines. Narrow roads resulting from road construction or lane closures. The vehicle is driven on a temporary lane or section with a closed lane resulting from
road construction where there may be multiple white (yellow) lane lines or they are
interrupted.
 The tire pressures are not adjusted to the specified pressure. Tires of a different specified size are used, such as an emergency spare tire.
CAUTION
Heed the following cautions so that the Lane-keep Assist System (LAS) & Lane Departure
Warning System (LDWS) can operate normally.
 Do not modify the suspensions. Always use wheels of the specified type and size for the front and rear wheels. Consult
an Authorized Mazda Dealer for tire replacement.
NOTE
 When the turn signal lever is operated for a lane change, the Lane-keep \
Assist System
(LAS) & Lane Departure Warning System (LDWS) is automatically disabled. The
Lane-keep Assist System (LAS) & Lane Departure Warning System (LDWS) becomes
operational again when the turn signal lever is returned and the system detects white
(yellow) lane lines while the vehicle is being driven normally within \
its vehicle lane.

NOTE
 Under the following conditions, the radar sensor (front) may not be able to detect
vehicles ahead or obstructions correctly and each system may not operate normally.
 The rear surface of a vehicle ahead does not reflect radio waves effectively, such as
an unloaded trailer or an automobile with a loading platform covered by a soft top,
vehicles with a hard plastic tailgate, and round-shaped vehicles.
 Vehicles ahead with low vehicle height and thus less area for reflecting radio waves. Visibility is reduced due to a vehicle ahead casting off water, snow, or sand from its
tires and onto your windshield. The trunk/luggage compartment is loaded with heavy objects or the r ear passenger
seats are occupied. Ice, snow, or soiling is on the front surface of the front emblem. During inclement weather such as rain, snow, or sand storms. When driving near facilities or objects emitting str ong radio waves.
 Under the following conditions, the radar sensor (fr ont) may not be able to detect
vehicles ahead or obstructions.
 The beginning and end of a curve. Roads with continuous curves. Narrow lane roads due to road construction or lane closures. The vehicle ahead enters the radar sensor's blind spot. The vehicle ahead is running abnormally due to accident or vehicle damag\
e. Roads with repeated up and down slopes Driving on poor r oads or unpaved roads. The distance between your vehicle and the vehicle ahead is extr emely short. A vehicle suddenly comes close such as by cutting into the lane.
 To prevent incorrect operation of the system, use tires of the same specified size,
manufacturer, brand, and tread pattern on all four wheels. In addition, do not use tires
with significantly different wear patterns or tire pressures on the same vehicle (Including
the temporary spare tire).
 If the battery power is weak, the system may not operate correctly. If the vehicle is driven on a road with little traffic and few vehicles ahead or obstructions
for the radar sensor (front) to detect, the sensor detects that the radar sensor (front) is
dirty and the Smart Brake Support/Smart City Brake Support (SBS/SCBS) \
Warning Light
(amber) may be temporarily turned on. However, it does not indicate a malfunction.

When Driving
Tire Pressure Monitoring System
CAUTION
 Each tire, including the spare (if provided), should be checked monthly when cold and
inflated to the inflation pressure recommended by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. (If your vehicle has tires of a different size than the
size indicated on the vehicle placard or tire inflation pressure label, you should determine
the proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle has been equipped with a tire pressure monitoring
system (TPMS) that illuminates a low tire pressure telltale when one or more of your tires
is significantly under-inflated. Accordingly, when the low tire pressure telltale illuminates,
you should stop and check your tires as soon as possible, and inflate them to the proper
pressure. Driving on a significantly under-inflated tire causes the tire to overheat and can
lead to tire failure. Under-inflation also reduces fuel efficiency and tire tread life, and may
affect the vehicle's handling and stopping ability.
Please note that the TPMS is not a substitute for proper tire maintenance, and it is the
driver's responsibility to maintain correct tire pressure, even if under-inflation has not
reached the level to trigger illumination of the TPMS low tire pressure telltale.
Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when
the system is not operating properly.
The TPMS malfunction indicator is combined with the low tire pressure telltale. When the
system detects a malfunction, the telltale will flash for approximately one minute and then
remain continuously illuminated. This sequence will continue upon subsequent vehicle
start-ups as long as the malfunction exists. When the malfunction indicator is illuminated,
the system may not be able to detect or signal low tire pressure as intended. TPMS
malfunctions may occur for a variety of reasons, including the installation of replacement
or alternate tires or wheels on the vehicle that prevent the TPMS from functioning properly.
Always check the TPMS malfunction telltale after replacing one or more tires or wheels on
your vehicle to ensure that the replacement or alternate tires and wheels allow the TPMS to
continue to function properly.
 To avoid false readings, the system samples for a little while before indicating a problem. As
a result it will not instantaneously register a rapid tire deflation or blow out.

Maintenance and Care
Owner Maintenance
Tires
For reasons of proper performance, safety,
and better fuel economy, always maintain
recommended tire inflation pressures and
stay within the recommended load limits
and weight distribution.
WARNING
Using Different Tire Types:
Driving your vehicle with different
types of tires is dangerous. It could
cause poor handling and poor braking;
leading to loss of control.
Except for the limited use of the
temporary spare tire, use only the
same type tires (radial, bias-belted,
bias-type) on all four wheels.
Using Wrong-Sized Tires: Using any other tire size than what is
specified for the vehicle (page
9-10)
is dangerous. It could seriously affect
ride, handling, ground clearance,
tire clearance, and speedometer
calibration. This could cause you to
have an accident. Use only tires that
are the correct size specified for the
vehicle.
Tire Inflation Pressure
WARNING
Always inflate the tires to the correct
pressure: Overinflation or underinflation of tires
is dangerous. Adverse handling or
unexpected tire failure could result in a
serious accident.
Refer to Tires on page
9-10.
Use only a Mazda-genuine tire valve
cap: Use of a non-genuine part is
dangerous as the correct tire air
pressure cannot be maintained if the
tire valve becomes damaged. If the
vehicle is driven under this condition,
the tire air pressure will decrease which
could result in a serious accident. Do
not use any part for the tire valve cap
that is not a Mazda-genuine part.
Inspect all tire pressures monthly
(including the spare) when the tires are
cold. Maintain recommended pressures for
the best ride, handling, and minimum tire
wear.
Refer to the specification charts (page
9-10).
(With tire pressure monitoring system)
After adjusting the tire pressure,
initialization of the tire pressure
monitoring system is necessary to make
the system operate normally.
Refer to Tire Pressure Monitoring System
Initialization on page
4-154.

Maintenance and Care
Owner Maintenance
*Some models.
CAUTION
 Do not use your temporary spare tire
rim with a snow tire or a conventional
tire. Neither will properly fit and could
damage both tire and rim.
 The temporary spare tire has a tread life
of less than 5,000 km (3,000 miles). The
tread life may be shorter depending on
driving conditions.
 The temporary spare tire is for limited
use, however, if the tread wear solid-
band indicator appears, replace the tire
with the same type of temporary spare
(page
6-43).
NOTE
Tires degrade over time, even when
they are not being used on the road. It
is recommended that tires generally be
replaced when they are 6 years or older.
Heat caused by hot climates or frequent
high loading conditions can accelerate
the aging process. You should replace the
spare tire when you replace the other road
tires due to the aging of the spare tire. The
period in which the tire was manufactured
(both week and year) is indicated by a
4-digit number.
Refer to Tire Labeling on page
8-25.
Replacing a Wheel
WARNING
Always use wheels of the correct size on
your vehicle:Using a wrong-sized wheel is
dangerous. Braking and handling
could be affected, leading to loss of
control and an accident.
CAUTION
A wrong-sized wheel may adversely
affect:
 Tire fit Wheel and bearing life Ground clearance Snow-chain clearance Speedometer calibration Headlight aim Bumper height Tire Pressure Monitoring System*
NOTE
 When replacing a wheel, make sure
the new one is the same as the original
factory wheel in diameter, rim width,
and offset (inset/outset).
 For details, contact an Authorized
Mazda Dealer.
Proper tire balancing provides the best
riding comfort and helps reduce tread
wear. Out-of-balance tires can cause
vibration and uneven wear, such as
cupping and flat spots.
