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 6-50).

Break-In Period
▼Break-In Period

economy, and life of the vehicle.
Do not race the engine.
Do not maintain one constant speed,
either slow or fast, for a long period of
time.
Do not drive constantly at full-throttle or
high engine rpm for e xtended periods of
time.
Avoid unnecessary hard stops.
Avoid full-throttle starts.
Saving Fuel and Protection of the Environment
▼Saving Fuel and Protection of the
Environment
How you operate your Mazda determines
how far it will travel
on a tank of fuel. Use
these suggestions to help save fuel and
reduce CO
2.
Avoid long warm-ups. Once the engine
runs smoothly, begin driving.
Avoid fast starts.
Drive at lower speeds.
Anticipate when to apply the brakes
(avoid sudden braking).
Follow the maintenance schedule and
have an Authorized Mazda Dealer
perform inspections and servicing.
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.

▼Wrench Indication/Indicator Light
The wrench indication/indicator light is
displayed/turns on under the following
conditions.
When the preset maintenance period has
arrived.
Refer to the Information section in the
Mazda Connect Owner's Manual.
CAUTION

When the maintenance period arrives,
have your vehicle inspected by an
Authorized Mazda Dealer as soon as
possible. If maintenance is neglected, a
decrease in vehicle performance may
occur which could cause damage.
Have your vehicle inspected before the
maintenance period arrives.
 If the vehicle continues to be driven
after the engine oil replacement period
has passed, it could cause damage to
the engine. Replace the engine oil
before the maintenance period arrives.
NOTE
The wrench indication/indicator light
may display/turn on earlier than the
preset period depending on vehicle
usage conditions.
Whenever the engine oil is replaced, a
reset of the vehicle engine control unit is
necessary.
Refer to the Informat ion section in the
Mazda Connect Owner's Manual.

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 Pressu
re Monitoring System
(TPMS) Warning Indication/Warning
Light (Flashing) on page 7-33.
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 tir e 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.

Operating Tips
▼Operating Tips
Operate the climate control system with
the engine running.
To prevent the battery from being
discharged, do not leave the fan control
switch 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.
(With A/C switch)
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. If the
wrong type of refrigerant is used, it
could result in a ser ious malfunction of
the air conditioner. Consult a
professional, government certified
repairer for the inspection or repair
because a special device is required for
the air conditi oner maintenance.
For details, consult an Authorized
Mazda Dealer.
