Maintenance
Recommended Engine Oil
Use a genuine engine oil or another commercial engine oil of suitable type and
viscosity (for the ambient temperature) as shown in the image that follows.
Oil is a major contributor to your engine’s performance and longevity. If you drive
the vehicle with insufficient or deteriorated oil, the engine may fail or be damaged.
*1:Formulated to improve fuel economy.
■Synthetic oil
You may also use synthetic motor oil if it is labeled with the API Certification Seal
and is the specified viscosity grade.

• Honda Genuine Motor Oil•API service SN or higher grade fuel-
efficient oil
• API Certification Mark "Starburst"

Engine Oil Additives
Your vehicle does not require oil additives. In fact,
they may adversely affect the engine performance
and durability.
The following seal indicates the oil is energy
conserving and that it meets the American Petroleum
Institute’s late st requirements.

uuMaintenance Under the Hood uCooling System
Maintenance
Cooling System
This coolant is premixed with 50% antifreeze and 50% water. Do not add any
straight antifreeze or water.
We recommend you check the engine coolant level every time you refuel. Check the
reserve tank first. If it is completely empty, also check the coolant level in the
radiator. Add the engine coolant accordingly.
1. Make sure the engine and radiator are cool.
2. Check the amount of coolant in the reserve tank.
u If the coolant level is below the MIN
mark, add the specified coolant until it
reaches the MAX mark.
3. Inspect the cooling system for leaks.
Specified coolant: Honda Long Life Antifreeze/Coolant Type 2
■Reserve Tank
1Cooling System
NOTICE
Genuine Honda engine coolant is a 50/50 mixture of
antifreeze and water that can withstand freezing at
temperatures as low as about -31°F (-35°C). If your
vehicle is consistently subjected to temperatures below
this, the concentration of antifreeze in the coolant
should be increased. Consult a dealer for details.
If Honda antifreeze/coolant is not available, you may use
another major brand of non-silicate coolant as a
temporary replacement. Check that it is a high quality
coolant recommended for aluminum engines.
Continued use of any non-Honda coolant can result in
corrosion, causing the cooling system to malfunction or
fail. Have the cooling system flushed and refilled with
Honda antifreeze/coolant as soon as possible.
Do not add rust inhibitors or other additives to your
vehicle's cooling system. They may not be compatible
with the coolant or with the engine components.
3WARNING
Removing the radiator cap while the
engine is hot can cause the coolant to spray
out, seriously scalding you.
Always let the engine and radiator cool
down before removing the radiator cap.
