MAZDA MODEL 6 2021 Owners Manual

About the SCR system
WARNING
Be careful not to allow the DEF to run out. If the DEF completely runs out, the SCR system will
not operate normally:
If the vehicle runs out of DEF, the vehicle speed is restricted in steps to prevent contaminants
from being exhausted. When the remaining dist ance-to-empty reaches 0 km (0 miles) in the
final stage, the engine is forced
to idle. For replenishment of the DEF supply, consult an
Authorized Mazda Dealer.
CAUTION
Use a Mazda genuine product or a product conforming to ISO22241-1 for DEF. If
incompatible DEF is used, the SCR system may not operate normally. For the recommended
DEF, consult the nearest Authorized Mazda Dealer.
NOTE
When the remaining distance-to-empty is 640 km (400 miles) or shorter while the DEF
warning indication is displayed, the SCR warning light turns on and the vehicle speed is
restricted. In addition, if there is a problem with the SCR system/DEF and the remaining
distance-to-empty is 200 km (125 miles) or sh orter, the SCR warning light flashes and the
vehicle speed is restricted.
DEF needs to be replenished periodically according to the scheduled maintenance
information. If a warning message is displa yed in the multi-information display or the
SCR warning light flashes, consult an Authorized Mazda Dealer.
Normally, the vehicle can be driven about 12,000 km (7,500 miles) before the DEF needs
to be replenished.

▼Engine Exhaust (Carbon monoxide)
WA R N I N G
Do not drive your vehicle if you smell exhaust gas inside the vehicle:
Engine exhaust gas is dangerous. This gas contai
ns carbon monoxide (CO), which is colorless,
odorless, and poisonous. When inhaled, it can cause loss of consciousness and death. If you
smell exhaust gas inside the vehicle, keep a ll windows fully open and contact an Authorized
Mazda Dealer immediately.
Do not run the engine when inside an enclosed area:
Running the engine inside an enclosed area, such as a garage, is dangerous. Exhaust gas,
which contains poisonous carbon monoxide , could easily enter the cabin. Loss of
consciousness or even death could occur.
Open the windows or adjust the heating or cooling system to draw fresh air when idling the
engine:
Exhaust gas is dangerous. When the vehicle is stopped with the windows closed and the
engine running for a long time even in an op en area, exhaust gas, which contains poisonous
carbon monoxide, could enter the cabin. Loss of consciousness or even death could occur.
Clear snow from underneath and around your vehicle, particularly the tail pipe, before
starting the engine:
Running the engine when a vehi cle is stopped in deep snow is dangerous. The exhaust pipe
could be blocked by the snow, allowing exhaust gas to enter the cabin. Because exhaust gas
contains poisonous carbon monoxide, it could cause loss of consciousness or even death to
occupants in the cabin.

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.

CAUTION
(SKYACTIV-G 2.5 and SKYACTIV-G 2.5T for
U.S.A. and Canada)
If the check fuel cap warning light
illuminates, the fuel-filler cap may not be
properly installed. If the warning light
illuminates, park your vehicle safely off the
right-of-way, remove the fuel-filler cap and
reinstall it correctly. After the cap has been
correctly installed, the fuel cap warning
light may continue to illuminate until a
number of driving cycles have been
completed. A drive cycle consists of starting
the engine (after four or more hours with
the engine off) and driving the vehicle on
city and highway roads.
Continuing to drive with the check fuel cap
warning light illuminated could cause the
check engine light to illuminate as well.

Power Windows
The windows can be opened/closed by operating the power window switches.
WA R N I N G
Make sure the opening is clear before closing a window:
Closing a power window is dangerous. A person's hands, head, or even neck could be caught
by the window and result in serious injury or even death. This warning applies especially to
children.
Never allow children to play with power window switches:
Power window switches that are not locked wi th the power window lock switch would allow
children to operate power windows unintentionally, which could result in serious injury if a
child's hands, head or neck becomes caught by the window.
Make sure nothing blocks the window just before it reaches the fully closed position or while
fully holding up the power window switch:
Blocking the power window just before it reac hes the fully closed position or while fully
holding up the power window switch is dangerous.
In this case, the jam-safe function cannot prevent the window from closing all the way. If
fingers are caught, seriou s injuries could occur.
NOTE
When driving with only 1 of the rear windows open, your ears might experience a
resonating sound. However, this does not indicate a problem. The sound can be reduced by
slightly opening a front window or by ch anging the size of the rear window opening.
