Be sure the vehicle is on a level surface.
Warm up the engine to normal operating temperature.
Turn it off and wait at least 5 minutes for the oil to return to the oil pan.
Pull out the dipstick, wipe it clean, and reinsert it fully.
Pull it out again and examine the level.
The level is normal if it is between the MIN and MAX marks.
If it is near or below MIN, add enough oil to bring the level to MAX.
Do not overfill the engine oil. This may cause engine damage.
Make sure the O-ring on the dipstick is positioned properly before reinserting the dipstick.
Reinsert the dipstick fully.
Contact an Authorized Mazda Dealer for a battery replacement purchase.
If the buttons on the transmitter are inoperable and the operation indicator light does not flash, the battery may be dead.
Replace with a new battery before the transmitter becomes unusable.
Make sure the battery is installed correctly. Battery leakage could occur if it is not installed correctly.
When replacing the battery, be careful not to touch any of the internal circuitry and electrical terminals, bend the electrical terminals, or get dirt in the transmitter as the transmitter could be damaged.
There is the danger of explosion if the battery is not correctly replaced.
Dispose of used batteries according to the following instructions.
Insulate the plus and minus terminals of the battery using cellophane or equivalent tape.
Never disassemble.
Never throw the battery into fire or water.
Never deform or crush.
Replace only with the same type battery (CR2025 or equivalent).
The following conditions indicate that the battery power is low:
The KEY indicator light (green) flashes in the instrument cluster for about 30 seconds after the engine is turned off (for vehicles with a type A instrument cluster (Search), messages are displayed in the instrument cluster).
The system does not operate and the operation indicator light on the transmitter does not flash when the buttons are pressed.
The system's operational range is reduced.
Replacing the battery at an Authorized Mazda Dealer is recommended to prevent damage to the key. If replacing the battery by yourself, follow the instruction.
Replacing the key battery
Press the knob and pull out the auxiliary key.
Twist a tape-wrapped flathead screwdriver in the direction of the arrow and open the cover slightly.
Insert the tape-wrapped flathead screwdriver into the gap and slide it in the direction of the arrow.
Twist the flathead screwdriver in the direction of the arrow and remove the cover.
Remove the battery cap, then remove the battery.
Insert a new battery with the positive pole facing up, and then cover the battery with the battery cap.
Close the cover.
Reinsert the auxiliary key.
Be careful not to allow the rubber ring shown in the figure to be scratched or damaged.
If the rubber ring detaches, reattach it before inserting a new battery.
Replacing the fuses on the vehicle's left side
If the electrical system does not work, first inspect the fuses on the vehicle's left side.
Make sure the ignition is switched off, and other switches are off.
Open the fuse panel cover.
Pull the fuse straight out with the fuse puller provided on the fuse block located in the engine compartment.
Inspect the fuse and replace it if it is blown.
Insert a new fuse of the same amperage rating, and make sure it fits tightly. If it does not fit tightly, have an expert install it. We recommend an Authorized Mazda Dealer.
If you have no spare fuses, borrow one of the same rating from a circuit not essential to vehicle operation, such as the AUDIO or OUTLET circuit.
Always replace a fuse with a genuine Mazda fuse or equivalent of the same rating. Otherwise you may damage the electric system.
Reinstall the cover and make sure that it is securely installed.
Replacing the fuses under the hood
If the headlights or other electrical components do not work and the fuses in the cabin are normal, inspect the fuse block under the hood. If a fuse is blown, it must be replaced. Follow these steps:
Make sure the ignition is switched off, and other switches are off.
Remove the fuse block cover.
If any fuse but the MAIN fuse is blown, replace it with a new one of the same amperage rating.
Do not replace the main fuse and multiplex slow blow fuse by yourself. Have an Authorized Mazda Dealer perform the replacement:
Replacing these fuses by yourself is dangerous because they are high current fuses. Incorrect replacement could cause an electrical shock or a short circuit resulting in a fire.
Reinstall the cover and make sure that it is securely installed.
