Before Performing Maintenance
Inspection and Maintenance
For your safety, perform all listed inspections and maintenance to keep your vehicle in good condition. If you become aware of any abnormality (noise, smell, insufficient brake fluid, oil residue on the ground, etc.), have your vehicle inspected by a dealer. (Note, however, that service at a dealer is not mandatory to keep your warranties in effect.)
Types of Inspection and Maintenance
Routine inspections
Perform inspections before long distance trips, when washing the vehicle, or when refueling.
Periodic inspections
- Check the brake fluid level monthly.
- Check the tire pressure monthly. Examine the tread for wear and foreign objects.
- Check the operation of the exterior lights monthly.
- Check the condition of the wiper blades at least every six months.
U.S. models
Maintenance, replacement, or repair of emissions control devices and systems may be done by any automotive repair establishment or individuals using parts that are “certified” to EPA standards.
According to state and federal regulations, failure to perform maintenance on the maintenance main items marked with # will not void your emissions warranties. However, all maintenance services should be performed in accordance with the intervals indicated by the driver information interface.
If you want to perform complex maintenance tasks that require more skills and tools, you can purchase a subscription to the Service Express website at https://techinfo.honda.com.
If you want to perform maintenance yourself, make sure that you have the necessary tools and skills first. After performing maintenance, update the records in the separate maintenance booklet.
Safety When Performing Maintenance
Some of the most important safety precautions are given here. However, we cannot warn you of every conceivable hazard that can arise in performing maintenance. Only you can decide whether you should perform a given task.
Maintenance Safety
- To reduce the possibility of fire or explosion, keep cigarettes, sparks, and flames away from the battery and all fuel related parts.
- Never leave rags, towels, or other flammable objects under the hood.
- Heat from the surrounding parts can ignite them, causing a fire.
- To clean parts, use a commercially available degreaser or parts cleaner, not gasoline.
- Wear eye protection and protective clothing when working with the battery or compressed air.
- Engine exhaust contains carbon monoxide, which is poisonous and can kill you.
- Only operate the engine if there is sufficient ventilation.
WARNING
Improperly maintaining this vehicle or failing to correct a problem before driving can cause a crash in which you can be seriously hurt or killed.

- If you drive in dusty conditions, replace the air cleaner element every 15,000 miles (24,000 km).
- If you drive primarily in urban areas that have high concentrations of soot in the air from industry and from diesel-powered vehicles, replace the dust and pollen filter every 15,000 miles (24,000 km).
- Driving in mountainous areas at very low vehicle speeds results in higher transmission temperatures. This requires transmission fluid changes more frequently than recommended by the Maintenance Minder.
