To reset the maintenance required light, turn the ignition switch to the ON position without starting the engine. Press the trip reset button on the dashboard, then turn the ignition off while holding the button. Turn the ignition back to ON while still holding the button, and the light will reset.
For optimal performance, use 5W-20 viscosity oil that meets API Service SL or higher standards. Check your owner’s manual for specific recommendations.
Improve fuel efficiency by maintaining proper tire pressure, performing regular engine tune-ups, using recommended oil, and avoiding aggressive driving behaviors.
The recommended tire pressure is typically 30 psi for both front and rear tires, but you should verify this with the label on the driver’s side door jamb or the owner’s manual.
To replace the cabin air filter, open the glove box and disconnect the dampener arm. Squeeze the sides of the glove box to drop it down, then remove the filter cover and replace the old filter with a new one.
If the engine overheats, turn off the air conditioning and turn on the heater to maximum. Pull over safely, turn off the engine, and let it cool. Check coolant levels and inspect for leaks once the engine is cool.
Check the fuse associated with the power windows, inspect the window switch for damage, and ensure the window motor is operational. If these steps do not work, consider consulting a professional.
Common causes of rough idle include dirty fuel injectors, a clogged air filter, faulty spark plugs, or vacuum leaks. Regular maintenance can help prevent these issues.
To change the spark plugs, disconnect the battery, remove the engine cover, and unplug the ignition coil connectors. Remove the old spark plugs using a spark plug socket, then install new ones and reassemble.
Honda recommends replacing the timing belt every 60,000 to 100,000 miles. Refer to your owner’s manual for model-specific recommendations.
