Improper or incomplete service may result in problems. This section gives instructions only for items that are easy to perform.
As explained in the Introduction (Search), several procedures can be done only by a qualified service technician with special tools.
Improper owner maintenance during the warranty period may affect warranty coverage. Refer to Introduction (Search) for owner's responsibility in protecting your investment. For details, read the separate Mazda Warranty statement provided with the vehicle. If you are unsure about any servicing or maintenance procedure, have it done by an Authorized Mazda Dealer.
There are strict environmental laws regarding the disposal of waste fluids. Please dispose of your waste properly and with due regard to the environment.
We recommend that you entrust the fluid changes of your vehicle to an Authorized Mazda Dealer.
Do not perform maintenance work if you lack sufficient knowledge and experience or the proper tools and equipment to do the work. Have maintenance work done by a qualified technician:
Performing maintenance work on a vehicle is dangerous if not done properly. You can be seriously injured while performing some maintenance procedures.
If you must run the EV system while working under the hood, make certain that you remove all jewelry (especially rings, bracelets, watches, and necklaces) and all neckties, scarves, and similar loose clothing before getting near the cooling fan which may turn on unexpectedly:
Working under the hood with the EV system operating is dangerous. It becomes even more dangerous when you wear jewelry, loose clothing or have long hair or a long beard.
Either can become entangled in moving parts and result in injury.
Pull over to a safe location, then switch the power switch 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 EV system has stopped and the motor compartment temperature is high. You could be hit by the fan and seriously injured.
Do not leave items in the motor compartment:
After you have finished checking or doing servicing in the motor compartment, do not forget and leave items such as tools or rags in the motor compartment.
Tools or other items left in the motor compartment could cause EV system damage or a fire leading to an unexpected accident.
Opening the Hood
-
With the vehicle parked, pull the release handle to unlock the hood.
-
Insert your hand into the hood opening, slide the latch lever in the direction of the arrow as shown in the illustration, and lift up the hood.
-
Grasp the support rod in the padded area and secure it in the support rod hole indicated by the arrow to hold the hood open.

Motor Compartment Overview
Inspecting Coolant Level
Do not use a match or live flame in the motor compartment. DO NOT ADD COOLANT WHEN THE EV SYSTEM IS HOT:
A hot EV system is dangerous. If the EV system has been running, parts of the motor compartment can become very hot. You could be burned. Carefully inspect the coolant in the coolant reservoir, but do not open it.
Pull over to a safe location, then switch the power switch 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 EV system has stopped and the motor compartment temperature is high. You could be hit by the fan and seriously injured.
Do not remove either cooling system cap when the EV system and radiator are hot:
When the EV system and radiator are hot, scalding coolant and steam may shoot out under pressure and cause serious injury.
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 the cooling system.
Replace any that are swollen or deteriorated.
The coolant should be between the FULL and LOW marks on the coolant reservoir when the EV system is cool.

If it is at or near LOW, add enough coolant to the coolant reservoir to provide freezing and corrosion protection and to bring the level to FULL.
Securely tighten the coolant reservoir tank cap after adding coolant.
-
Radiator coolant will damage paint.
Rinse it off quickly if spilled.
-
If the “FL22” mark is shown on or near the cooling system cap, use of FL-22 is recommended when replacing coolant. Using coolant other than FL-22 may cause serious damage to the cooling system.

If the coolant reservoir is empty or new coolant is required frequently, consult an Authorized Mazda Dealer.
Replacing Windshield Wiper Blades
When the wipers no longer clean well, the blades are probably worn or cracked.
Replace them.
-
To prevent damaging a windshield wiper blade, wiper arm, or the hood, perform the following procedure.
-
Before lifting the windshield wiper blades off the windshield, always move them to the service position.
-
When putting the windshield wiper blades back on the windshield, make sure that they are in the service position before switching the power switch ON and operating the windshield wipers.
-
-
Replace with Mazda genuine wiper blades. If they are replaced with wiper blades other than a Mazda genuine product, they may not wipe with the same efficiency as the genuine product.
-
To prevent damage to the wiper arms and other components, do not try to sweep the wiper arm by hand.
-
Do not bend the blade rubber unnecessarily when replacing it. Otherwise, the metal stiffener in the blade may deform and the windshield wiper operation may be adversely affected.
-
Do not hold a wiper blade by its end when raising the wiper arm. Otherwise, the part may deform and the wiping performance may lower.
-
Forcefully lowering the wiper arms could damage the wiper arm and blade, and may scratch or crack the windshield.
You can replace the wiper blades yourself, however you cannot replace the wiper arms.
If you want to replace the wiper arms, consult an Authorized Mazda Dealer.
Replace the wiper blades using the following procedure.
-
Move the wipers to the service positions using the following procedure.
-
Switch the power switch ON.
-
Switch the power switch OFF.
-
Press up the wiper switch to the MIST position 2 times within 30 seconds after switching the power switch OFF.
When the procedure is completed, the wipers operate and they stop at the service positions.
-
-
Raise the wiper arms.
-
Slide the blade component in the direction of the arrow while pressing the wiper arm tab to remove the blade component from the wiper arm.
-
Pull the blade rubber in the direction of the arrow and slide it to a position where the blade holder groove can be checked.
-
Pull the end of the blade rubber from the blade holder groove in the direction of the arrow and remove the blade rubber from the blade holder.
-
Insert the end of the new blade rubber into the groove of the blade holder until it contacts the end of the blade holder.
-
After pulling the blade rubber in the direction of the arrow and sliding the blade rubber to a position to check the blade holder groove, slide the blade rubber end in the opposite direction.
-
Make sure that the blade rubber is correctly installed to the blade holder.
-

-
Slowly lower the wiper arms onto the windshield.
To prevent damage to the windshield let the wiper arm down easily, do not let it slap down on the windshield.
-
Move the wipers to their initial positions using the following procedure.
-
Make sure that the wipers are set on the windshield.
-
Switch the power switch ON.
-
Press up the wiper switch to the MIST position 1 time.
When the procedure is completed, the wipers operate and they stop at the initial positions.
-

Replacing a Tire
Always use tires that are in good condition:
Driving with worn tires is dangerous. Reduced braking, steering, and traction could result in an accident.
Replace all four tires at the same time:
Replacing just one tire is dangerous. It could cause poor handling and poor braking resulting in loss of vehicle control. Mazda strongly recommends that you replace all four tires at the same time.
If a tire wears evenly, a wear indicator will appear as a solid band across the tread.
Replace the tire when this happens.

-
New tread
-
Worn tread
-
Tread wear indicator
You should replace the tire before the band crosses the entire tread.
Tires degrade over time, even when they are not being used on the road. It is recommended that tires generally be replaced when they are 6 years or older. Heat caused by hot climates or frequent high loading conditions can accelerate the aging process. The period in which the tire was manufactured (both week and year) is indicated by a 4-digit number.
Refer to Tire Labeling (Search).
