warning light MAZDA MODEL 6 2021 Owners Manual

Selective Catalytic Reduction (SCR) System(SKYACTIV-D 2.2)
The SCR system is designed to reduce nitrogen oxide (NOx) in the exhaust gas and purify
the exhaust gas by injecting it w ith Diesel Exhaust Fluid (DEF).
WARNING
Be careful not to allow the DEF to run out. If the DEF completely runs out, the SCR system will
not operate normally.
When the remaining DEF is low, a message is displayed on the multi-information display, and
the SCR warning light turns on/flashes.
Refer to Selective Catalytic Reduction (SCR) System Indications on page 4-237.
In this case, consult an Authorized Mazda De aler. If DEF needs to be replenished, add DEF
following the specified procedure.
Refer to Diesel Exhaust Fluid (DEF) Replenishment on page 6-30.
NOTE
DEF needs to be replenished periodically according to the scheduled maintenance
information.
Normally, the vehicle can be driven about 12,000 km (7,500 miles) before the DEF needs
to be replenished. However, it may need to be replenished earlier depending on the
driving and environmental conditions (such as putting a high load on the engine while
driving or driving the vehicle at high altitudes).
The sound of the SCR system operating may be heard from the area under the vehicle,
however, this does not indicate a problem.
▼ Selective Catalytic Reduction
(SCR) System Indications

▼Replacing a Wheel
WARNING
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.
