2021 MAZDA MODEL 6 fuel pump

Fuel and Engine Exhaust Precautions
▼Fuel Requirements (SKYACTIV-G 2.5, SKYACTIV-G 2.5T)
Vehicles with catalytic converters or oxygen sensors must use O
NLY UNLEADED FUEL,
which will reduce exhaust emissions and keep spark plug fouling to a minimum.

To achieve maximum engine performance, use the specified fuel.
Fuel Octane Rating*1 (Anti-knock index)
Regular unleaded fuel 87 [(R+M)/2 method] or above (91 RON or ab ove)
*1 U.S. federal law requires that octane ratings be posted on gas station pumps.
Fuel with a rating lower than 87 octane (91 RON) will negativel y affect the emission control
system performance and could also cause engine knocking and ser ious engine damage.
CAUTION
USE ONLY UNLEADED FUEL.
Leaded fuel is harmful to the catalytic co nverter and oxygen sensors and will lead to
deterioration of the emission control system and or failures.
 This vehicle can only use oxygenated fuels containing no more than 10 % ethanol by
volume. Damage to the vehicle may occur when ethanol exceeds this recommendation, or
if the gasoline contains any methanol. Stop us ing gasohol of any kind if your vehicle engine
is performing poorly.
 Never add fuel system additives other than a Mazda genuine product, otherwise the
emission control system could be damaged. Consult an Authorized Mazda Dealer for
details.
Gasoline blended with oxygenates such as alcohol or ether compo unds are generally
referred to as oxygenated fuels. The common gasoline blend that can be used with your
vehicle is ethanol blended at no more than 10 %. Gasoline conta ining alcohol, such as
ethanol or methanol, may be marketed under the name "Gasohol".

Vehicle damage and drivability problems resulting from the use of the following may not be
covered by the warranty.
Gasohol containing mo re than 10 % ethanol.
Gasoline or gasohol containing methanol.
Leaded fuel or leaded gasohol.

▼Fuel Requirements
(SKYACTIV-D 2.2)
The vehicle will operate efficiently on diesel fuel with specif ication Ultra-Low Sulfur Diesel
(ULSD, 15 ppm sulfur or less) f uel that meets the ASTM D975 standard or the equivalent.
Fuel grade labels are visible on fuel-filler lid, therefore, ve rify the fuel grade before
refueling. If the fuel grade cannot be verified, ask the gas st ation attendant.
CAUTION
Never use fuel other than specification Ultra-Low Sulfur Diesel (ULSD, 15 ppm sulfur or less)
fuel that meets the ASTM D975 standard or the equivalent for your vehicle. Use of gasoline
or kerosene in diesel engines will resu lt in fuel system and engine damage.
 Never use diesel fuel with concentrations of methyl ester bio-diesel higher than 5 % (B5),
such as B20 or B100.
 Never add fuel system additives other than a Mazda genuine product, otherwise the
emission control system could be damaged. Consult an Authorized Mazda Dealer for
details.
 If any type of incorrect fuel is accidently pu mped into the fuel tank, do not turn on the
engine and drive the vehicle. Consult an Authorized Mazda Dealer for assistance.
Turning on the engine or driving the vehicle with the incorrect fuel could cause damage to
the fuel pump and fuel injectors.
NOTE
Fuel for winter driving is available. Ask the gas station attendant for details.
When refueling, always add at least 10 L (2.6 US gal, 2.2 Imp gal) of fuel.
Low outside temperatures
When the outside temperature is low, diesel fuel (light oil) ma y freeze and clog the fuel
pipe, leading to probl ems such as the engine not starting. When driving to a cold region, add
winter grade diesel fuel as soon as possible.
WA R N I N G
Never use engine starting assist additives:
Using engine starting assist additives is dangerous because they may cause a vehicle
explosion or a vehicle runaway condition, leading to serious injury or death.

Fuel-Filler Lid and Cap
WARNING
When removing the fuel-filler cap, loosen
the cap slightly and wait for any hissing to
stop, then remove it:
Fuel spray is dangerous. Fuel can burn skin
and eyes and cause illness if ingested. Fuel
spray is released when there is pressure in
the fuel tank and the fuel-filler cap is
removed too quickly.
Before refueling, stop the engine, and
always keep sparks and flames away from
the filler neck:
Fuel vapor is dangerous. It could be ignited
by sparks or flames causing serious burns
and injuries.
Additionally, use of the incorrect fuel-filler
cap or not using a fuel-filler cap may result
in a fuel leak, which could result in serious
burns or death in an accident.
Do not continue refueling after the fuel
pump nozzle shuts off automatically:
Continuing to add fuel after the fuel pump
nozzle has shut off automatically is
dangerous because overfilling the fuel tank
may cause fuel overflow or leakage. Fuel
overflow and leakage could damage the
vehicle and if the fuel ignites it could cause
a fire and explosion resulting in serious
injury or death.
CAUTION
Always use only a genuine Mazda fuel-filler
cap or an approved equivalent, available
at an Authorized Mazda Dealer. The wrong
cap can result in a serious malfunction of
the fuel and emission control systems.
(SKYACTIV-G 2.5 and SKYACTIV-G 2.5T for
U.S.A. and Canada)
It may also cause the check engine light in
the instrument cluster to illuminate.
▼ Refueling
Before refueling, close all the doors,
windows, and the trunk lid, and switch the
ignition OFF.
1. To open the fuel-filler lid, pull the
remote fuel-filler lid release.

This does not indicate an abnormality.Starting the Engine
WA R N I N G
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

short range.
The engine can be started when the push
button start is pressed from off, ACC, or
ON.
The push button start system functions
(function which can start the engine by
only carrying the key) can be

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 Authorized Mazda
Dealer for details. If the push button
start system functions have been
deactivated, you can start the engine by
following the procedure indicated when
the key battery goes dead.
Refer to Engine Start Function When
Key Battery is Dead on page 4-9.
After starting a cold engine, the engine
speed increases and a whining sound
from the engine compartment can be
heard.

NOTE
After starting the engine, the push
button start indicator light (amber)
turns off and the ignition switches to
the ON position.
(SKYACTIV-G 2.5, SKYACTIV-G
2.5T)
After pressing the push button start
and before the engine starts, the
operation sound of the fuel pump
motor from near the fuel tank can be
heard, however, this does not
indicate a malfunction.
(SKYACTIV-D 2.2)
The starter does not rotate until
the glow indicator light turns off.
If the ignition is left switched ON
for a long period of time without
the engine running after the glow
plugs are warmed up, the glow
plugs may warm up again which
will illuminate the glow indicator
light.
When starting the engine, do not
release the brake pedal until the
glow indicator light in the
instrument cluster turns off and
the engine starts, after pressing
the push button start.
If the brake pedal is released
before the engine starts, depress
the brake pedal again and press
the push button start to start the
engine.
8. After starting the e ngine, let it idle for
about 10 seconds.
NOTE
Do not use high engine speeds until
reaching the operating temperature.
(SKYACTIV-G 2.5, SKYACTIV-G
2.5T)
Whether the engine is cold or
warm, it should be started without
the use of the accelerator.
If the engine does not start the first
time, refer to Starting a Flooded
Engine under Emergency Starting.
If the engine still does not start,
have your vehicle inspected by an
Authorized Mazda Dealer (page
7-18).
(SKYACTIV-D 2.2)
If the ambient temperature is lower
than about
－ 10 °C (14 °F), the
maximum engine speed may not be
attained for about 3 minutes after
the engine starts to protect the
engine.
