Do not operate a vehicle with a
damaged seat belt:
Using a damaged seat belt is
dangerous. An accident could damage
the belt webbing of the seat belt in
use. A damaged seat belt cannot
provide adequate protection in a
collision. Have an Authorized Mazda
Dealer inspect all seat belt systems in
use during an accident before they are
used again.
Have your seat belts changed
immediately if the pretensioner or
load limiter has been expended:
Always have an Authorized Mazda
Dealer immediately inspect the seat
belt pretensioners and air bags after
any collision. Like the air bags, the seat
belt pretensioners and load limiters
will only function once and must be
replaced after any collision that caused
them to deploy. A seat belt with an
expended pretensioner or load limiter
is still better than wearing no seat belt
at all; however, if the seat belt
pretensioners and load limiters are not
replaced, the risk of injury in a collision
will increase.
Positioning the Shoulder Portion of
the Seat Belt:
Improper positioning of the shoulder
portion of the seat belt is dangerous.
Always make sure the shoulder portion
of the seat belt is positioned across
your shoulder and near your neck, but
never under your arm, on your neck, or
on your upper arm.Positioning the Lap Portion of the Seat
Belt:
The lap portion of the seat belt worn
too high is dangerous. In a collision,
this would concentrate the impact
force directly on the abdominal area,
causing serious injury. Wear the lap
portion of the belt snugly and as low as
possible.
CAUTION
Belt retraction may become difficult if
the belts and rings are soiled, so try to
keep them clean. For more details
about cleaning the seat belts, refer to
"Seat Belt Maintenance" (page
6-49).

Turbocharger Information(SKYACTIV-G 2.5T)
▼Turbocharger Information
(SKYACTIV-G
2.5T)
CAUTION

After driving at freeway speeds or up
a long hill, idle the engine at least 30
seconds before stopping it.
Otherwise, the turbocharger could
be damaged. However, when i-stop
operates, idling is unnecessary.
 Racing or over-revving the engine,
particularly after it's just been
started, can damage the
turbocharger.
 To protect the engine from damage,
the engine is designed so that it
cannot be raced just after starting it
in extremely cold weather.
The turbocharger greatly enhances
engine power. Its advanced design
provides improved operation and
requires minimum maintenance.

To get the most from it, observe the
following.
1. Change engine oil and filter according to Scheduled
Maintenance.
Refer to Scheduled Maintenance
(U.S.A. and Puerto Rico) on page
6-4.
Refer to Scheduled Maintenance
(Canada) on page 6-6.
Refer to Scheduled Maintenance
(Mexico) on page 6-8.
2. Use only recommended engine oil (page 6-16). Extra additives are
NOT recommended.

Charging the M Hybrid battery
The M Hybrid battery is charged
automatically during engine operation
and by deceleration regeneration.
Therefore, it is not necessary to charge
the battery from outside of the vehicle.
CAUTION
Drive the vehicle for about 30 minutes
once every few months because
self-discharge occurs gradually if the
vehicle is not driven for a long period
of time. If the M Hybrid battery
becomes completely discharged and
M Hybrid cannot be activated, contact
an Authorized Mazda Dealer.
▼M Hybrid Precautions
For vehicle maintenance or repairs, or
when scrapping the vehicle, consult an
Authorized Mazda Dealer.
Handling the M Hybrid battery
Technical knowledge and skill are
necessary in handling the M Hybrid
battery.
WARNING
To ensure safe and correct handling of
the M Hybrid battery, always heed the
following precautions:

Do not remove the M Hybrid battery.
 Do not resell, transfer, or modify the
M Hybrid battery.
 Do not use the battery on vehicles
other than those equipped with the
M Hybrid battery.
If the M Hybrid battery is not handled
properly, the following may occur and
cause serious injury:
 Touching an unattended or illegally
abandoned M Hybrid battery may
cause electrocution.
 If the M Hybrid battery is used on a
vehicle other than one equipped
with M Hybrid (including modified
vehicles), accidents such as
electrocution, heat generation,
smoking , combustion, and
explosions, or an electrolyte leakage
may occur.
Scrapping Your Vehicle and Disposing
of the M Hybrid battery
The M Hybrid battery must be recycled
to prevent accidents involving it. When
scrapping your vehicle, replacing the M
Hybrid battery, or disposing of the M
Hybrid battery, consult an Authorized
Mazda Dealer. Please cooperate in
ensuring that the vehicle's M Hybrid
battery is recycled.
WARNING
Dispose of the M Hybrid battery
appropriately:
If the M Hybrid battery is not recycled
appropriately, such as by leaving it
unattended or illegally abandoning it,
some other person may touch it which
could cause electrocution leading to
serious injury.
If an Accident Occurs
If the vehicle is involved in a collision,
M Hybrid may stop operating. In this
case, the charging sy stem warning light
turns on and M Hybrid cannot activate.
Park the vehicle in a safe place

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.▼ If there is a problem with the Tire
Pressure Monitoring System
(TPMS)
If the TPMS warning light flashes, there
may be a problem with the system.
Consult an Authorized Mazda Dealer
to have the system inspected.
Refer to Tire Pressure Monitoring
System (TPMS) Warning Indication/
Warning Light (Flashing) on page
7-28.
In the following cases, the system
cannot recognize the tire pressures
correctly and the TPMS warning light
may
flash.
There is equipment or a device
nearby emitting radio signals the
same as a tire pressure sensor.
A metallic object such as a
non-genuine electronic device is
installed near the center of the
dashboard (obstructs the radio
signals from the tire pressure sensors
to the receiver).
A device such as one of the following
is used in the cabin.
Electronic devices such as a
computer.
Converter devices such as a
DC-AC converter.
There is a large accumulation of
snow or ice around the vehicle tires.
The battery in a tire pressure sensor
is dead.
A wheel not equipped with a tire
pressure sensor is used.
Tires employing steel in the sidewall
of the tire are installed.
Tire chains are used.
