Release the retaining clip and pull out the old bulb. Insert the new bulb, secure the clip, replace the rubber cover, and reconnect the power connector.
Squeaking noises during braking can be caused by worn brake pads, dust accumulation, or moisture. Inspect the brake pads for wear and replace them if necessary. Cleaning the brake components may also resolve the issue.
To improve fuel efficiency, ensure regular maintenance, keep tires properly inflated, use recommended engine oil, and drive smoothly avoiding rapid acceleration and heavy braking. Removing excess weight and limiting the use of air conditioning can also help.
To update the navigation system, download the latest maps from the Mazda Update Toolbox on a computer. Insert the SD card from your vehicle's navigation system into the computer and follow the instructions to update the maps. Reinsert the SD card into the vehicle once the update is complete.
If the engine overheats, pull over safely and turn off the engine. Allow the engine to cool before checking coolant levels. If the coolant is low, add more if available. Seek professional assistance if the problem persists or if you notice leaks.
To change the cabin air filter, open the glove box and remove the limiting stop arm on the right side. Push in on both sides of the glove box to release it. Remove the filter cover, take out the old filter, and insert the new one. Reassemble in reverse order.
