Recommended Engine Oil

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.

This seal indicates the oil is energy conserving
and that it meets the American Petroleum
Institute’s latest requirements.

Use Honda Genuine Motor Oil or another
commercial engine oil of suitable viscosity for
the ambient temperature as shown.

Engine Coolant

Main

tenan

Engine Coolant

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.

Remove the engine compartment cover.

Engine Compartment Cover

P. 498

Check the amount of coolant in the reserve
tank.

If the coolant level is below the

MIN

mark, add the specified coolant until it
reaches the

MAX

mark.

Inspect the cooling system for leaks.

Specified coolant: Honda Long Life Antifreeze/Coolant Type 2

■

Reserve Tank

Engine Coolant

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.

WARNING

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.
