Essential Safety Equipment
SRS Air Bags
WARNING
Seat belts must be worn in air bag equipped vehicles:
Depending only on the air bags for protection during an accident is dangerous. Alone,
air bags may not prevent serious injuries. The appropriate air bags can be expected to
inÀ ate only in the ¿ rst accident, such as frontal, near frontal or side collisions that are
at least moderate. Vehicle occupants should always wear seat belts.

Children should not ride in the front passenger seat:
Placing a child, 12 years or under, in the front seat is dangerous. The child could be hit
by a deploying air bag and be seriously injured or even killed. A sleeping child is more
likely to lean against the door and be hit by the side air bag in moderate collision to the
front-passenger side of the vehicle. Whenever possible, always secure a child 12 years
and under on the rear seats with an appropriate child-restraint system for the child's
age and size.

Extreme Hazard! Never use a rear-facing child-restraint system on the front passenger
seat with an air bag that could deploy:
NEVER use a rearward facing child restraint on a seat protected by an ACTIVE
AIRBAG in front of it, DEATH or SERIOUS INJURY to the CHILD can occur.
Even in a moderate collision, the child-restraint system can be hit by a deploying air
bag and moved violently backward resulting in serious injury or death to the child. If
your vehicle is equipped with a front passenger air bag deactivation switch, always set
the switch to the OFF position when installing a rear-facing child-restraint system on
the front passenger seat.


Do not sit too close to the driver and front passenger air bags:
Sitting too close to the driver and front passenger air bag modules or placing hands or
feet on them is extremely dangerous. The driver and front passenger air bags inÀ ate
with great force and speed. Serious injuries could occur if someone is too close. The
driver should always hold onto only the rim of the steering wheel. The front seat
passenger should keep both feet on the À oor. Front seat occupants should adjust their
seats as far back as possible and always sit upright against the seatbacks with seat belts
worn properly.

Driving Tips
Snow Tyres
WARNING
Use only the same size and type tyres
(snow, radial, or non-radial) on all four
wheels:
Using tyres 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 tyres.
Use snow tyres on all four wheels
Do not exceed the maximum permissible
speed for your snow tyres or legal speed
limits.
E u r o p e
When snow tyres are used, select the
speci¿ ed size and pressure (page 9-9 ).
Tyre Chains
Check local regulations before using tyre
chains.
CAUTION
  Chains may affect 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 tyre; it may result in damage to
the vehicle and to the tyre. In some
models, the vehicle is not equipped
with a factory installed temporary
spare tyre.
  Do not use chains on roads that are
free of snow or ice. The tyres and
chains could be damaged.
  Chains may scratch or chip
aluminium wheels.
NOTE
If your vehicle is equipped with the tyre
pressure monitoring system, the system
may not function correctly when using
tyre chains.
Install the chains on the front tyres only.
Do not use chains on the rear tyres.

Driving Tips
Tyre chain selection (Europe)
Mazda recommends hexagon type
steel ring chains. Select the proper type
according to your tyre size.



Tyre size Tyre chain
215/60R16 Hexagon type
215/50R18 Hexagon type

NOTE
Although Mazda recommends hexagon
type steel ring chains, all chains within
the installation speci¿ cations may be
used.
Installation speci¿ cation (Europe)
When installing tyre chains, the distance
between the tyre tread and the chain must
be within the prescribed limits in the
following table.

Distance [Unit: mm (in)]
A B
MAX 9 (0.35) MAX 9 (0.35)

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 tyres 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 manoeuvring,
enhancing vehicle safety.

Refer to ABS (page 4-84 ) and TCS
(page 4-85 ).

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 4-36 .
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
tyre 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 tyres of the correct size
speci¿ ed for your Mazda on all
four wheels.
 


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


 Do not mix worn tyres. 

 The DSC may not operate correctly
when tyre chains are used or a
temporary spare tyre is installed
because the tyre 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 expert
repairer, we recommend an Authorised
Mazda Repairer.

When Driving
i-ACTIV AWD
*Some models.
i-ACTIV AWD Operation *
4WD provides excellent drivability on
snow-covered and ice-packed roads, sand
and mud, as well as on steep slopes and
other slippery surfaces.
A system malfunction or operation
conditions are indicated by a warning.
Refer to Warning Indication/Warning
Lights on page 4-36 .
WARNING
Never spin a wheel that is off the
ground:
Spinning a wheel that is off the ground
as a result of the vehicle being stuck
or in a ditch is dangerous. The drive
assembly could be seriously damaged
which could lead to an accident or
could even lead to overheating, oil
leakage, and a ¿ re.
4WD Driving
This vehicle has not been designed for the
purpose of off-road driving or rallies. Do
not attempt to drive over uneven or rocky
surfaces, or across rivers.
Although this vehicle is equipped with
4WD, acceleration, steering and braking
operations should be conducted in the
same manner as with a non-4WD vehicle,
with the emphasis placed on safe driving.
Tyres and Tyre Chains
The condition of the tyres plays a large
role in the performance of the vehicle.
Moreover, to prevent adverse effects to the
drive assembly, please note the following:
T y r e s
 




 When replacing tyres, always replace all
front and rear tyres at the same time.
 


 All tyres must be of the same size,
manufacture, brand and tread pattern.
Pay particular attention when equipping
snow or other types of winter tyres.
 


 Do not mix tread-worn tyres with
normal tyres.
 


 Inspect tyre inÀ ation pressures at the
speci¿ ed periods adjust to the speci¿ ed
pressures, and initialize the tyre pressure
monitoring system.
  Refer to Tyre Pressure Monitoring
System Initialization on page 4-201 .

NOTE
Check the tyre inÀ ation pressure label
attached to driver's door frame for the
correct tyre inÀ ation pressure.




 Make sure to equip the vehicle with
genuine wheels of the speci¿ ed size,
on all wheels. With 4WD, the system is
calibrated for all four wheels being of
the same dimensions.

When Driving
i-ACTIVSENSE
CAUTION
  When driving off-road in areas where there is grass or foliage, it is recommended that
the Smart City Brake Support [Reverse] (SCBS R) system be turned off.
  Always use tyres of the speci¿ ed size and the same manufacturer, brand, and tread
pattern on all 4 wheels. In addition, do not use tyres with signi¿ cantly different wear
patterns on the same vehicle. Do not use tyres with signi¿ cantly different wear patterns
on the same vehicle. Otherwise, the Smart City Brake Support [Reverse] (SCBS R)
system may not operate normally.
  If ice or snow is stuck on the ultrasonic sensors (rear) they may not be able to detect
obstructions correctly depending on the conditions. In such cases, the system may not
be able to perform controls correctly. Always drive carefully and pay attention to the
rear of the vehicle.

4–182
When Driving
i-ACTIVSENSE
CAUTION
  Always use tyres for all wheels that are of the speci¿ ed size, and the same
manufacturer, brand, and tread pattern. In addition, do not use tyres with signi¿ cantly
different wear patterns on the same vehicle as the system may not operate normally.
  The Forward Sensing Camera (FSC) includes a function for detecting a soiled
windscreen and informing the driver, however, depending on the conditions, it may not
detect plastic shopping bags, ice or snow on the windscreen. In such cases, the system
cannot accurately determine a vehicle ahead and may not be able to operate normally.
Always drive carefully and pay attention to the road ahead.
NOTE
  In the following cases, the Forward Sensing Camera (FSC) cannot detect target objects
correctly, and each system may be unable to operate normally.
 


 The height of the vehicle ahead is low.



 You drive your vehicle at the same speed as the vehicle ahead.



 Headlights are not turned on during the night or when going through a tunnel.

4–18 8
When Driving
i-ACTIVSENSE
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 reÀ ect 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 reÀ ecting radio waves.



 Visibility is reduced due to a vehicle ahead casting off water, snow, or sand from its
tyres and onto your windscreen.
 


 The luggage compartment is loaded with heavy objects or the rear 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 strong radio waves. 

 Under the following conditions, the radar sensor (front) 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 damage.



 Roads with repeated up and down slopes



 Driving on poor roads or unpaved roads.



 The distance between your vehicle and the vehicle ahead is extremely short.



 A vehicle suddenly comes close such as by cutting into the lane. 

 To prevent incorrect operation of the system, use tyres of the same speci¿ ed size,
manufacturer, brand, and tread pattern on all four wheels. In addition, do not use
tyres with signi¿ cantly different wear patterns or tyre pressures on the same vehicle
(Including the temporary spare tyre).
  If the battery power is weak, the system may not operate correctly. 
 If the vehicle is driven on a road with little traf¿ c 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.
