2021 MAZDA MODEL CX-5 maintenance schedule

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)
WARNING
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 al l windows fully open and contact an Authorized
Mazda Dealer immediately.

Break-In Period
No special break-in is necessary, but a few
precautions in the first 1,000 km (600
miles) may add to the performance,
economy, and life of the vehicle.
Do not race the engine.
Do not maintain one constant speed,
either slow or fast, for a long period of
time.
Do not drive constantly at full-throttle or
high engine rpm for extended periods of
time.
Avoid unnecessary hard stops.
Avoid full-throttle starts.
Do not tow a trailer.
Saving Fuel and Protectionof the Environment
How you operate your Mazda determines
how far it will travel on a tank of fuel. Use
these suggestions to help save fuel and
reduce CO
2.
Avoid long warm-ups. Once the engine
runs smoothly, begin driving.
Avoid fast starts.
Drive at lower speeds.
Anticipate when to apply the brakes
(avoid sudden braking).
Follow the maintenance schedule (page
6-4) and have an Authorized Mazda
Dealer perform inspections and
servicing.
Use the air conditioner only when
necessary.
Slow down on rough roads.
Keep the tires properly inflated.
Do not carry unnecessary weight.
Do not rest your foot on the brake pedal
while driving.
Keep the wheels in correct alignment.
Keep windows closed at high speeds.
Slow down when driving in crosswinds
and headwinds.
WA R N I N G
Never stop the engine when going down a
hill:
Stopping the engine when going down a
hill is dangerous. This causes the loss of
power steering and power brake control,
and may cause damage to the drivetrain.
Any loss of steering or braking control
could cause an accident.

Turbocharger Information (SKYACTIV-G 2.5T,SKYACTIV-D 2.2)
CAUTION
After driving at freeway speeds or up a long h ill, trailer towing for a long time, idle the
engine at least 30 seconds before stopping it. Otherwise, the turbocharger could be
damaged.
 Racing or over-revving the engine, particularly after it's just been started, can damage the
turbocharger.
 To protect the engine from damage, the engine is designed so that it cannot be raced just
after starting it in extremely cold weather.
The turbocharger greatly enhances engine power. Its advanced design provides improved
operation and requires minimum maintenance.

To get the most from it, observe the following.
1. Change engine oil and filter according to Scheduled Maintenance (page 6-4).
2. Use only recommended engine oil (page 6- 22). Extra additives are NOT recommended.

To restart after parking on an incline:
1. With the transaxle in P, start the engine. (Be sure to depress and hold the brake pedal.)
2. Shift into gear.
3. Release the parking brake (also the foot brake) and pull away from the wheel blocks.Stop; apply the parking brake and shift into P.
4. Have a helper retrieve the wheel blocks.
Fuel consumption
Trailer towing causes higher fuel consumption.
Maintenance
If you tow a trailer frequently, have your vehicle serviced as shown in Scheduled
Maintenance (page 6-4).

Selective Catalytic Reduction (SCR) System*
The SCR system is designed to reduce nitrogen oxide (NOx) in the exhaust gas and purify
the exhaust gas by injecting it with 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 4-261.
In this case, consult an Authorized Mazda Dealer. 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
As the remaining amount of Diesel Exhaust Fluid (DEF) lowers, the SCR system notifies
the driver using the following indications.
The vehicle speed may be restricted for a while even if the warning light turns off after
replenishing the DEF. To cancel the vehicle speed restriction immediately, switch the
ignition OFF after the warning light turns off and then switch the ignition ON again.
