erto Rico. Once engine oil flexib le maintenance is selected, the
vehicle calculates the remaining oil life based on the engine oper ‐
ating conditions. The vehicle lets you know when an oil change is
due by illuminating the wrench indicator light in the instrument
cluster. Mazda Genuine 0W-20 oil is required to achieve optimum
performance.

This procedure is intended for vehicles with
the engine oil flexible maintenance setting
selected.
After replacing the engine oil, have a repa ir shop such as an Authorized Mazda Dealer
perform the initialization (engine oil data rese tting) of the recorded value. If the value
recorded by the computer is not initialized, the wrench indicator light may not turn off or it
may turn on earlier than normal.
NOTE

the following procedure:
1. Switch the ignition OFF.
2. Switch the ignition ON with the selector pressed and continue pressing the selector for
about 5 seconds until the master warning light
flashes.

3. After the master warning light flashes for several seconds, the initialization is
completed.
▼ Inspecting Engine Oil Level

surface.
2. Warm up the engine to normal operating temperature.
3. Turn it off and wait at least 5 minutes
for the oil to return to the oil pan.

▼Battery Maintenance
To get the best service from a battery:
Keep it securely mounted.
Keep the top clean and dry.
Keep terminals and connections clean,
tight, and coated with petroleum jelly or
terminal grease.
Rinse off spilled electrolyte immediately
with a solution of water and baking
soda.
If the vehicle will not be used for an
extended time, disconnect the battery
cables and charge the battery every 6
weeks.
▼Battery Replacement
Contact an Authorized Mazda Dealer for
battery replacement.
Key Battery Replacement
If the buttons on the transmitter are
inoperable and the operation indicator
light does not flash, the battery may be
dead.
Replace with a new battery before the
transmitter becomes unusable.
CAUTION

Make sure the battery is installed
correctly. Battery leakage could occur if it
is not installed correctly.
 When replacing the battery, be careful
not to touch any of the internal circuitry
and electrical terminals, bend the
electrical terminals, or get dirt in the
transmitter as the transmitter could be
damaged.
 There is the danger of explosion if the
battery is not correctly replaced.
 Dispose of used batteries according to
the following instructions.
 Insulate the plus and minus terminals
of the battery using cellophane or
equivalent tape.
 Never disassemble.
 Never throw the battery into
fire or
water.
 Never deform or crush.
 Replace only with the same type battery
(CR2032 or equivalent).
The following conditions indicate that the
battery power is low:
The KEY indicator light (green) flashes
in the instrument cluster for about 30
seconds after the engine is switched
OFF.

Severe braking

After rotation, inflate all tire pressures to
specification (page 9-7) and inspect the
lug nuts for tightness.
CAUTION
Rotate unidirectional tires and radial tires
that have an asymmetrical tread pattern or
studs only from front to rear, not from side
to side. Tire performance will be reduced if
rotated from side to side.
▼ Replacing a Tire
WA R N I N G
Always use tires that are in good condition:
Driving with worn tires is dangerous.
Reduced braking, steering, and traction
could result in an accident.
Replace all four tires at the same time:
Replacing just one ti
re is dangerous. It
could cause poor handling and poor
braking resulting in loss of vehicle control.
Mazda strongly recommends that you
replace all four tires at the same time.
If a tire wears evenly, a wear indicator will
appear as a solid band across the tread.
Replace the tire when this happens.
New tread Tread wear indicator
Worn tread
You should replace the tire before the band
crosses the entire tread.
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.
▼Temporary Spare Tire
Inspect the temporary spare tire at least
monthly to make sure it is properly
inflated and stored.
NOTE
The temporary spare tire condition
gradually deteriorates even if it has not
been used.
The temporary spare tire is easier to
handle because of its construction which is
lighter and smaller than a conventional

tire. This tire should be used only for an
emergency and only for a short distance.

Use the temporary spare tire only until the
conventional tire is repaired, which should
be as soon as possible.
Refer to Tires on page 9-7.

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 6-38).
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
WA R N I N G
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.

WARNING
Never touch the glass portion of a halogen
bulb with your bare hands and always
wear eye protection when handling or
working around the bulbs:
When a halogen bulb breaks, it is
dangerous. These bulbs contain
pressurized gas. If one is broken, it will
explode and serious injuries could be
caused by the flying glass.
If the glass portion is touched with bare
hands, body oil could cause the bulb to
overheat and explode when lit.
Always keep halogen bulbs out of the reach
of children:
Playing with a halogen bulb is dangerous.
Serious injuries could be caused by
dropping a halogen bulb or breaking it
some other way.
CAUTION
When removing the lens or lamp unit using
a flathead screwdriver, make sure that the
flathead screwdriver does not contact the
interior terminal. If the flathead screwdriver
contacts the terminal, a short circuit may
occur.
NOTE
To replace the bulb, contact an
Authorized Mazda Dealer.
If the halogen bulb is accidentally
touched, it should be cleaned with
rubbing alcohol before being used.
Use the protective cover and carton for
the replacement bulb to dispose of the
old bulb promptly and out of the reach
of children.
