▼Ty re s
When towing a trailer, make sure all
tyres are inflated to the recommended
cold-tyre pressure, as indicated on the
tyre pressure chart on the driver's door
frame. Trailer tyre size, load rating, and
inflation pressures should conform to
tyre manufacturer specifications.
WARNING
Never use the temporary spare tyre
when towing:
Using the temporary spare tyre on your
vehicle when towing a trailer is
dangerous as it could result in tyre
failure, loss of control, and injury to
vehicle occupants.
▼Safety Chains
Safety chains must be used as a
precautionary measure should the
trailer become unintentionally
unhitched. They should cross under the
trailer tongue and attach to the hitch.
Leave enough slack to allow full turns.
Consult literature published by your
trailer or hitch manufacturer for more
details.
WARNING
Make sure the safety chain is securely
attached to both the trailer and the
vehicle prior to departure:
Towing a trailer without using a safety
chain securely attached to both the
trailer and the vehicle is dangerous. If
damage occurs to the coupling unit or
hitch ball, the trailer could wander into
another lane and cause a collision.
▼Trailer Lights
CAUTION
Do not connect a trailer lighting system
directly to the lighting system of your
Mazda. This may damage your
vehicle's electrical system and lighting
systems. To connect the lighting
system, consult an expert repairer (we
recommend an Authorised Mazda
Repairer)
▼Trailer Brakes
Check the Maximum trailer
towing-load table in Weight Limits
(page 3-61), and if your trailer weight
exceeds the value in the TOTAL
TRAILER WEIGHT (Trailer without
brake), trailer brakes are required.
If your trailer has brakes, make sure
they meet regulations.
WARNING
Do not connect a hydraulic
trailer-brake system to your vehicle's
brake system:
Connecting a hydraulic trailer-brake
system directly to the vehicle brake
system is dangerous and will result in
inadequate braking and possible injury.
▼Trailer Towing Tips
Before driving
xVerify that your Mazda maintains a
near-normal attitude when a loaded
or unloaded trailer is connected. Do
not drive if it has an abnormal
front-up or front-down position.
Inspect for incorrect nose weight,
worn suspension parts, and trailer
overloading. Have the vehicle
inspected by an expert repairer (we

Ignition Switch
▼Push Button Start Positions
The system operates only when the key
is within operational range.
Each time the push button start is
pressed, the ignition switches in the
order of
off, ACC, and ON. Pressing
the push button start again from ON
switches the ignition
off.
1. Indicator light
2. Push button start
NOTE
xThe engine starts by pressing the
push button start while depressing
the clutch pedal (manual
transmission) or the brake pedal
(automatic transmission). To switch
the ignition position, press the push
button start without depressing the
pedal.
xDo not leave the ignition switched
ON while the engine is not running.
Doing so could result in the battery
going dead. If the ignition is left in
ACC (For automatic transmission,
the selector lever is in the P position,
and the ignition is in ACC), the
ignition switches off automatically
after about 25 minutes.
Off
The power supply to electrical devices
turns off and the indicator light
(amber) also turns off.
In this position the steering wheel is
locked.
WARNING
Before leaving the driver's seat,
always switch the ignition off, set the
parking brake, and make sure the
selector lever is in P (automatic
transmission) position or in 1st gear
or R (manual transmission):
Leaving the driver's seat without
switching the ignition off, setting the
parking brake, and shifting the selector
lever to P (automatic transmission)
position or to 1st gear or R (manual
transmission) is dangerous.
Unexpected vehicle movement could
occur which could result in an
accident.
In addition, if your intention is to leave
the vehicle for even a short period, it is
important to switch the ignition
off, as
leaving it in another position will
disable some of the vehicle's security
systems and run the battery down.
NOTE
(Locked steering wheel)
If the push button start indicator light
(green) is
flashing , a message is
displayed on the multi-information,
and the beep sound is heard, this
indicates that the steering wheel is not
unlocked. To unlock the steering
wheel, press the push button start
while moving the steering wheel left
and right.

WARNING
Radio waves from the key may affect
medical devices such as pacemakers:
Before using the key near people who
use medical devices, ask the medical
device manufacturer or your physician
if radio waves from the key will affect
the device.
NOTE
xThe key must be carried because the
key carries an immobilizer chip that
must communicate with the engine
controls at short range.
xThe engine can be started when the
push button start is pressed from off,
ACC, or ON.
xThe push button start system
functions (function which can start
the engine by only carrying the key)
can be deactivated to prevent any
possible adverse effect on a user
wearing a pacemaker or other
medical device. If the system is
deactivated, you will be unable to
start the engine by carrying the key.
Consult an expert repairer (we
recommend an Authorised Mazda
Repairer) for details. If the push

M Hybrid
▼M Hybrid
M Hybrid uses the Integrated Starter-Generator (ISG) with excellent power
generation efficiency to generate electricity from the kinetic energy generated when
the vehicle decelerates. The system uses the electrical power stored in the M Hybrid
battery, which is a large-capacity battery to improve driveability and fuel economy by
reducing engine load and providing motor assist. In addition, the ISG provides quiet
engine restarting after the engine is stopped by after the i-stop function (idling stop).

battery.
WARNING
Heed the following cautions to
prevent burns and electrical shock:
¾Never remove and disassemble the
brackets and connectors securing the
terminal part, wiring harness, and
the M Hybrid battery.
¾Never touch the M Hybrid battery
because it becomes extremely hot
under direct sunlight or after driving.
¾Because the M Hybrid battery is
especially dangerous when wet,
never touch it.
NOTE
The M Hybrid battery has a certain
battery life. Battery life
differs
depending on how the vehicle is used
and the driving conditions.

WARNING
Never touch the areas where high
current is flowing:
Never touch a M Hybrid related part.
Otherwise, it could lead to an
electrical shock or burns causing
serious injury.
Never touch electrical wiring that may
be protruding into or outside of the
cabin:
Otherwise, it could lead to an
electrical shock or burns causing
serious injury.
Never touch any area where
electrolyte is visible or electrolyte is
leaking from the area:
If any electrolyte from the M Hybrid
battery gets in the eyes or on the skin,
it could cause loss of vision or skin
reactions. In the unlikely event that
electrolyte comes into contact with the
eyes or skin, flush with large quantities
of water immediately and seek
immediate medical attention.
Do not come near the vehicle if
electrolyte is leaking from the M
Hybrid battery:
Even if the M Hybrid battery is
damaged, large quantities of
electrolyte will not flow out due to the
internal structure of the battery,
however, in the unlikely event that it
does, it will produce steam. The steam
contains properties that can irritate the
eyes and skin, and could cause acute
poisoning if absorbed.
Never approach objects that are on
fire or extremely hot:
Electrolyte in the M Hybrid battery may
cause a fire.
If the vehicle catches fire, extinguish
the fire using an ABC fire
extinguisher:
Only extinguish a fire with water when
large amounts of water is available
such as from a fire hydrant.
