Engine Coolant

Main

tenan

ce

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. 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

■

Checking the Coolant

1

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.

WARNING

Removing the reserve tank 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 reserve tank
cap.

Continuously Variable Transmission (CVT) Fluid

NOTICE

Do not mix Honda HCF-2 transmission fluid with
other transmission fluids.
Using a transmission fluid other than Honda HCF-2
transmission fluid may adversely affect the operation
and durability of your vehicle’s transmission, and
damage the transmission.
Any damage caused by using a transmission fluid that
is not equivalent to Honda HCF-2 transmission fluid is
not covered by Honda’s new vehicle limited warranty.

Manual Transmission Fluid

If Honda MTF is not available, you may use the API
certificated SAE 0 W-20 or 5 W-20 viscosity motor oil
as a temporary measure.
Replace with MTF as soon as possible. Motor oil does
not contain the proper additives for the transmission
and continued use can cause decreased shifting
performance and lead to transmission damage.

NOTICE

Halogen bulbs get very hot when lit.
Oil, perspiration, or a scratch on the glass can cause
the bulb to overheat and shatter.

The headlight aim is set by the factory, and does not
need to be adjusted. However, if you regularly carry

and protect the glass from contact with your skin or
hard objects. If you touch the glass, clean it with
denatured alcohol and a clean cloth.
