Engine Coolant
This coolant is premixed with 50% an tifreeze 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.Remove the engine compartment cover.
2 Engine Compartment Cover P. 513
2.Check the amount of coolant in the reserve
tank.
3. If the coolant level is below the MIN mark,
add the specified coolant until it reaches
the MAX mark.
4. Inspect the cooling system for leaks.
Specified coolant: Honda Long Li fe Antifreeze/Coolant Type 2
■Reserve Tank
1Engine Coolant
NOTICE
Genuine Honda engine coolan t is a 50/50 mixture of
antifreeze and water that can withstand freezing at
temperatures as low as a bout -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 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 anti freeze/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.

uuCleaning uExterior Care
Maintenance
If you get gasoline, oil, engine coolant, or battery fluid on resin coated parts, they
may be stained or the coating may peel. Prom ptly wipe it away using a soft cloth and
clean water.
Wipe using a glass cleaner.
Aluminum is susceptible to deterioration caused by salt and other road
contaminants. Use a sponge and mild detergent to wipe away promptly.
Be careful not to use harsh chemicals (inc luding some commercial wheel cleaners) or
a stiff brush. They can damage the clear coat of the aluminum alloy wheels that help
keep the aluminum from corroding and tarnishing.
