coolant temperature MAZDA MODEL CX-5 SKYACTIV-D 2019 Owner's Manual

NOTE
Changing the coolant should be done by
an Authorized Mazda Dealer.
Inspect the antifreeze protection and
coolant level in the coolant reservoir at
least once a year―at the beginning of the
winter season ―and before traveling where
temperatures may drop below freezing.
Inspect the condition and connections of
all cooling system and heater hoses.
Replace any that are swollen or
deteriorated.
The coolant should be at full in the
radiator and between the F and L marks on
the coolant reservoir when the engine is
cool.
SKYACTIV-G 2.0 and SKYACTIV-G
2.5
SKYACTIV-G 2.5T
SKYACTIV-D 2.2
If it is at or near L, add enough coolant to
the coolant reservoir to provide freezing
and corrosion protection and to bring the
level to F.
Securely tighten the coolant reservoir tank
cap after adding coolant.
CAUTION
 Radiator coolant will damage paint.
Rinse it off quickly if spilled.

▼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.
Rinse the wheels thoroughly with
lukewarm or cold water. Also, be sure to
clean the wheels after driving on dusty
or salted roads to help prevent
corrosion.
Avoid washing your vehicle in an
automatic car wash th
at uses high-speed
or hard brushes.
(19-inch wheel vehicle)
If your aluminum wheels lose luster,
apply wax which contains no polishing
powder.
▼ Plastic Part Maintenance
When cleaning the plastic lenses of the
lights, do not use gasoline, kerosene,
rectified spirit, paint, thinner, highly
acidic detergents, or strongly alkaline
detergents. Otherwise, these chemical
agents can discolor or damage the
surfaces resulting in a significant loss in
functionality. If plastic parts become
inadvertently exposed to any of these
chemical agents, flush with water
immediately.
If plastic parts such as the bumpers
become inadvertently exposed to
chemical agents or fluids such as
gasoline, oil, engine coolant, or battery
fluid, it could cause discoloration,
staining, or paint peeling. Wipe off any
such chemical agents or fluids using a
soft cloth immediately.
High water temperature and high water
pressure car washers are available
depending on the type of high pressure
car washer device. If the car washer
nozzle is put too close to the vehicle or
aimed at one area for an extended period
of time, it could deform plastic parts or
damage the paint.
Do not use wax containing compounds
(polish). Otherwise, it could result in
paint damage.
In addition, do not use an electrical or
air tool to apply wax. Otherwise, the
frictional heat generated could result in
deformation of plastic parts or paint
damage.

Overheating
If the temperature gauge indicates
overheating or the high engine coolant
temperature warning light turns on, the
vehicle loses power, or you hear a loud
knocking or pinging noise, the engine is
probably too hot.
WA R N I N G
Pull over to a safe location, then switch
the ignition off and make sure the fan is
not running before attempting to work
near the cooling fan:
Working near the cooling fan when it is
running is dangerous. The fan could
continue running indefinitely even if the
engine has stopped and the engine
compartment temperature is high. You
could be hit by the fan and seriously
injured.
Do not remove either cooling
system cap when the engine and radiator
are hot:
When the engine and radiator are hot,
scalding coolant and steam may shoot out
under pressure and cause serious injury.
Open the hood ONLY after steam is no
longer escaping from the engine:
Steam from an overheated engine is
dangerous. The escaping steam could
seriously burn you.
If the temperature gauge indicates
overheating or the high engine coolant
temperature warning light turns on:

1. Drive safely to the side of the road and park off the right-of-way.
2. Put a vehicle with an automatic transaxle in park (P), a manual
transaxle in neutral.
3. Apply the parking brake.
4. Turn off the air conditioner.
5. Check whether coolant or steam is escaping from the engine
compartment.

If steam is coming from the engine
compartment:
Do not go near the front of the vehicle.
Stop the engine.
Wait until the steam dissipates, then
open the hood and start the engine.

If neither coolant nor steam is
escaping:
Open the hood and idle the engine
until it cools.
CAUTION
If the cooling fan does not operate
while the engine is running, the engine
temperature will increase. Stop the
engine and call an Authorized Mazda
Dealer.
6. Make sure the cooling fan is operating, then turn off the engine after the
temperature has decreased.

SignalWarning
Charging System Warn-
ing Indication/Warning
Light If the warning light illuminates while driving, it indicates a malfunction of the alter-
nator or of the charging system.
Drive to the side of the ro
ad and park off the right-of -way. Consult an Authorized
Mazda Dealer.
CAUTION
Do not continue driving when the charging system warning light is illuminated be‐
cause the engine could stop unexpectedly.
Engine Oil Warning Light This warning light indicates low engine oil pressure.
CAUTION
Do not run the engine if the oil pressure is
low. Otherwise, it could result in extensive
engine damage.
If the light illuminates or the warning indication is displayed while driving:
1. Drive to the side of the road and pa rk off the right-of-way on level ground.
2. Turn off the engine and wait 5 minutes fo r the oil to drain back into the oil pan.
3. Inspect the engine oil level (page 6-28). If it's low, add the appropriate amount of
engine oil while being careful not to overfill.
CAUTION
Do not run the engine if the oil level is low. Otherwise, it could result in extensive
engine damage.
4. Start the engine and check the warning light.

If the light remains illuminated even though th e oil level is normal or after adding oil,
stop the engine immediately and have your vehicle towed to an Authorized Mazda
Dealer.
(Red)
High Engine Coolant
Temperature Warning Indication/Warning Light The light flashes when the engine coolant
temperature is extremely high, and illumi-
nates when the engine coolant temperature increases further.
Handling Procedure
Flashing light
Drive slowly to reduce engine load until you can find a safe place to stop the vehicle
and wait for the engine to cool down.
Illuminated light
This indicates the possibility of overheati ng. Park the vehicle in a safe place immedi-
ately and stop the engine.
Refer to Overheating on page 7-19.
CAUTION
Do not drive the vehicle with the high engine coolant temperature warning light illumi‐
nated. Otherwise, it could resu lt in damage to the engine.
