*4: If you drive regularly in very high temperatures (over 110°F, 43°C), in very low temperatures (under
-20°F, -29°C), or towing a trailer, replace every 60,000 miles (U.S.) / 100,000 km (Canada).
*5: Driving in mountainous areas at very low vehicle speeds or trailer towing results in higher level of mechanical (Shear) stress to fluid. This requires differential fluid changes more frequently than
recommended by the Maintenance Minder. If you regularly drive your vehicle under these conditions,
have the differential fluid changed at 7,500 miles (12,000 km), then every 15,000 miles (24,000 km).

Maintenance
Recommended Engine Oil
Oil is a major contribu tor to your engine’s
performance and longevity. If you drive the
vehicle with insufficient or deteriorated oil,
the engine may fail or be damaged.
This seal indicates the oil is energy conserving
and that it meets the American Petroleum
Institute’s latest requirements.
Use a Genuine Honda Motor Oil or another
commercial engine oil of suitable viscosity for
the ambient temperature as shown.
■Synthetic oil
You may also use synthetic motor oil if it is labeled with the API Certification Seal
and is the specified viscosity grade.
• Genuine Honda Motor Oil
• Premium-grade 0W-20 detergent oil with an API Certification Seal on the
container.1 Recommended Engine Oil
Engine Oil Additives
Your vehicle does not require oil additives. In fact,
they may adversely affect the engine performance
and durability.

Wait approximately three minutes after turn ing the engine off before you check the
oil. 1.Remove the dipstick (orange).
2. Wipe the dipstick with a clean cloth or
paper towel.
3. Insert the dipstick back all the way into its
hole.
4. Remove the dipstick again, and check the
level. It should be between the upper and

If the oil level is near or below the lower mark, slowly
add oil, being careful not to overfill.
