To replace the cabin air filter, open the glove box and remove the limiting arm by pushing in on the sides to drop it down. Remove the screws or clips holding the access panel behind the glove box, and take out the old filter. Insert the new filter, ensuring the airflow direction arrow points correctly, and reassemble.
Begin by checking the A/C system fuses and relays. Inspect the refrigerant level and look for any leaks. Ensure the A/C compressor engages when the system is turned on. If problems persist, it may be necessary to seek professional diagnostics for electrical or mechanical issues.
To jump-start the vehicle, connect the positive cable to the positive terminal on the dead battery and the other positive end to the live battery. Connect the negative cable to the negative terminal on the live battery and attach the other negative end to an unpainted metal surface on the dead vehicle. Start the live vehicle, let it run for a few minutes, and then start the dead vehicle.
To check the transmission fluid level, ensure the vehicle is on a level surface and the engine is warm. With the engine running and in park, remove the transmission dipstick, wipe it clean, reinsert it fully, and then remove it again to check the fluid level. Add fluid if necessary, ensuring it meets the vehicle's specifications.
