Mazda CX-5 Owners Manual: Engine Coolant
Inspecting Coolant Level
WARNING
Do not use a match or live flame in the engine compartment. DO NOT ADD COOLANT WHEN THE ENGINE IS HOT:
A hot engine is dangerous. If the engine has been running, parts of the engine compartment can become very hot. You could be burned.
Carefully inspect the engine coolant in the coolant reservoir, but do not open it.
Switch the ignition to 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.
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.
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.
● Use only soft (demineralized) water in the coolant mixture.
Water that contains minerals will cut down on the coolant's effectiveness.
● Do not add only water. Always add a proper coolant mixture.
● The engine has aluminum parts and must be protected by an ethylene-glycol-based coolant to prevent corrosion and freezing.
● DO NOT USE coolants Containing Alcohol, methanol, Borate or Silicate.
These coolants could damage the cooling system.
● DO NOT MIX alcohol or methanol with the coolant. This could damage the cooling system.
● Do not use a solution that contains more than 60% antifreeze.
This would reduce effectiveness.
NOTE
If the “FL22” mark is shown on or near the cooling system cap, it is recommended to use Mazda Genuine FL22 engine coolant .
If the coolant reservoir is empty or new coolant is required frequently, consult an Authorized Mazda Dealer.
Engine Oil
NOTE
Changing the engine oil should be performed by an Authorized Mazda Dealer.

Push-Starting
Do not push-start your Mazda.
WARNING
Never tow a vehicle to start it:
Towing a vehicle to start it is dangerous. The vehicle being towed could surge
forward when its engine starts, causing the two vehicles to collide. The occupants
could be injured.

Do not push-start a vehicle that ...
Refrigerant System Service Cautions
Handling Insufficient Refrigerant Level
If an insufficient refrigerant level is detected at troubleshooting, do
not charge (add) the refrigerant. Because an accurate amount of refrigerant
cannot be determined from the pressure indicated on the manifold gauge, never
charge the refrige ...
Mass Air Flow (MAF) Sensor/Intake Air Temperature (Iat) Sensor No.1 Removal/Installation
NOTE:
Because the IAT sensor No.1 is integrated in the MAF sensor, replacing the
IAT sensor No.1 includes replacement of the MAF sensor/IAT sensor No.1.
1. Disconnect the negative battery cable..
2. Disconnect the MAF sensor/IAT sensor No.1 connector.
3. Remove the MAF sensor/IA ...
