Replenishment of DEF by an Authorized
Mazda Dealer is recommended. If you
want to replenish the DEF yourself,
follow the replenishment procedure
below.

Replenishment Procedure
1. Check the remaining amount of Diesel Exhaust Fluid (DEF) on the
multi-information display.

Fluid (DEF) and Maximum Driving
Distance Display (SKYACTIV-D 2.2)
on page 4-38.
3.8 L (1.0 US gal, 0.84 Imp gal) of
DEF or more needs to be added.
NOTE
The replenishment amount (reference)
according to the DEF level (%)
indication is as follows:

Tires
For reasons of proper performance, safety,
and better fuel economy, always maintain
recommended tire inflation pressures and
stay within the recommended load limits
and weight distribution.
WARNING
Using Different Tire Types:
Driving your vehicle with different types of
tires is dangerous. It could cause poor
handling and poor braking; leading to loss
of control.
Except for the limited use of the temporary
spare tire, use only the same type tires
(radial, bias-belted, bias-type) on all four
wheels.
Using Wrong-Sized Tires:
Using any other tire size than what is
specified for the vehicle (page 9-8) is
dangerous. It could seriously affect ride,
handling, ground clearance, tire clearance,
and speedometer calibration. This could
cause you to have an accident. Use only
tires that are the correct size specified for
the vehicle.
▼ Tire Inflation Pressure
WARNING
Always inflate the tires to the correct
pressure:
Overinflation or underinflation of tires is
dangerous. Adverse handling or
unexpected tire failure could result in a
serious accident.
Refer to Tires on page 9-8.
Use only a Mazda-genuine tire valve cap:
Use of a non-genuine part is dangerous as
the correct tire air pressure cannot be
maintained if the tire valve becomes
damaged. If the vehicle is driven under this
condition, the tire air pressure will decrease
which could result in
a serious accident. Do
not use any part for the tire valve cap that
is not a Mazda-genuine part.
Inspect all tire pressures monthly
(including the spare) when the tires are
cold. Maintain recommended pressures for
the best ride, handling, and minimum tire
wear.
Refer to the specification charts (page
9-8).
NOTE
Always check tire pressure when tires
are cold.
Warm tires normally exceed
recommended pressures. Do not release
air from warm tires to adjust the
pressure.
Underinflation can cause reduced fuel
economy, uneven and accelerated tire
wear, and poor sealing of the tire bead,
which will deform the wheel and cause
separation of tire from rim.
Overinflation can produce a harsh ride,
uneven and accelerated tire wear, and a
greater possibility of damage from road
hazards.
Keep your tire pressure at the correct
levels. If one frequently needs inflating,
have it inspected.

During cold weather or in coastal areas,
cover bright-metal parts with a coating
of wax or preservative heavier than
usual. It would also help to coat them
with noncorrosive petroleum jelly or
some other protective compound.
CAUTION
Do not use steel wool, abrasive cleaners, or
strong detergents containing highly
alkaline or caustic agents on
chrome-plated or anodized aluminum
parts. This may result in damage to the
protective coating and cause discoloration
or paint deterioration.
▼Underbody Maintenance
Road chemicals and salt used for ice and
snow removal and solv
ents used for dust
control may collect on the underbody. If
not removed, they will speed up rusting
and deterioration of such underbody parts
as fuel lines, frame, floor pan, and exhaust
system, even though these parts may be
coated with anti-corrosive material.

Thoroughly flush the underbody and
wheel housings with lukewarm or cold
water at the end of each winter. Try also to
do this every month.

Pay special attention to these areas
because they easily hide mud and dirt. It
will do more harm than good to wet
down the road grime without removing
it.

The lower edges of doors, rocker panels,
and frame members have drain holes that
should not be clogged. Water trapped there
will cause rusting.
WA R N I N G
Dry off brakes that have become wet by
driving slowly, releasing the accelerator
pedal and lightly applying the brakes
several times until the brake performance
returns to normal:
Driving with wet brakes is dangerous.
Increased stopping distance or the vehicle
pulling to one side when braking could
result in a serious accident. Light braking
will indicate whether the brakes have been
affected.
▼ Aluminum Wheel Maintenance
A protective coating is provided over the
aluminum wheels. Special care is needed
to protect this coating.
CAUTION
Do not use any detergent other than mild
detergent. Before using any detergent,
verify the ingredients. Otherwise, the
product could discolor or stain the
aluminum wheels.
NOTE
Do not use a wire brush or any abrasive
cleaner, polishing compound, or solvent
on aluminum wheels. They may damage
the coating.
Always use a sponge or soft cloth to
clean the wheels.

Starting a Flooded Engine(SKYACTIV-G 2.5 andSKYACTIV-G 2.5T)
If the engine fails to start, it may be
flooded (excessive fuel in the engine).

Follow this procedure:

1. If the engine does not start within 5
seconds on the first try, wait 10
seconds and try again.
2. Make sure the parking brake is on.
3. Depress the accelerator all the way and hold it there.
4. Depress the brake pedal, then press the push button start. If the engine starts,
release the accelerator immediately
because the engine will suddenly rev
up.
5. If the engine fails to start, crank it without depressing the accelerator.

If the engine still does not start using the
previous procedure, have your vehicle
inspected by an Authorized Mazda Dealer.
Push-Starting
Do not push-start your Mazda.
WA R N I N G
Never tow a vehicle to start it:
Towing a vehicle to start it is dangerous.
The vehicle being towed could surge
forward when its engine starts, causing the
2 vehicles to collide. The occupants could
be injured.
NOTE
You cannot start a vehicle with an
automatic transaxle by pushing it.
