uuMaintenance Under the Hood uEngine Coolant
Continued
Maintenance
Engine CoolantThis 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.Check the amount of coolant in the reserve
tank.
2. 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
1Engine CoolantNOTICEIf temperatures consistently below −22°F (−30°C) are
expected, the coolant mixture should be changed to
a higher concentration. Consult a dealer for more
information.
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 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.

1. Make sure the engine and radiator are
cool.
2. Turn the radiator cap counterclockwise to
relieve any pressure in the cooling system.
Do not push the cap down when turning.
3. Push down and turn the radiator cap
counterclockwise to remove it.
4. The coolant level should be up to the base
of the filler neck. Add coolant if it is low.
5. Put the radiator cap back on, and tighten it
fully.
6. Pour coolant into the reserve tank until it
reaches the MAX mark. Put the cap back
on the reserve tank.

any. Clean up any spills immediately; they can
damage components in the engine compartment.

Continuously Variable Transmission FluidSpecified fluid: HCF-2■
Manual Transmission FluidSpecified fluid: Honda Manual T ransmission Fluid (MTF)Models with continuously variable transmission
1Continuously Variable Transmission FluidNOTICEDo not mix HCF-2 with other transmission fluids.
Using a transmission fluid other than HCF-2 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 HCF-2 is not covered by Honda's
new vehicle warranty.
Models with manual transmission
1 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.

Brake/Clutch FluidUse the same fluid for both the brakes and clutch.
The fluid level should be between the MIN
and MAX marks on the side of the reservoir.
The fluid level should be between the MIN
and MAX marks on the side of the reservoir.Specified fluid: Honda Heavy Duty Brake Fluid DOT 3■
Checking the Brake Fluid
1Brake/Clutch FluidNOTICEBrake fluid marked DOT 5 is not compatible with your
vehicle's braking system and can cause extensive
damage.
If the specified brake fluid is not available, you should
use only DOT 3 or DOT 4 fluid from a sealed
container as a temporary replacement.
Using any non-Honda brake fluid can cause corrosion
and decrease the longevity of the system. Have the
brake system flushed and refilled with Honda Heavy
Duty Brake Fluid DOT 3 as soon as possible.
If the brake fluid level is at or below the MIN mark,
have a dealer inspect the vehicle for leaks or worn
brake pads as soon as possible.

High Beam Headlight
1Headlight BulbsNOTICEHalogen 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
heavy items in the trunk, have the aiming readjusted
at a dealer or by a qualified technician.
When replacing a halogen bulb, handle it by its base,
and protect the glass from contact with your skin or
hard objects. If you touch the glass, clean it with
