Continued
Maintenance
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.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 Coolant
NOTICE
You will need a more concentrated coolant if you are
driving in extremely cold temperature below −31°F
(−35°C). Consult your Honda dealer for details about
a suitable coolant mixture.
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 coolant system. They may not be compatible
with the coolant or with the engine components.

NOTICE
Pour the fluid slowly and carefully so you do not spill
any. Clean up any spills immediately; they can
damage components in the engine compartment.
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.Radiator Cap

4. Insert the dipstick all the way back into the
transmission securely, as shown in the image.
5. Remove the dipstick and check the fluid level.
uIt should be between the upper and
lower marks in the HOT range.
6. If the level is below the lower mark, add
fluid into the dipstick hole to bring it to the
level between the upper and lower marks,
and have your vehicle checked by a dealer immediately.

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.

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 for leaks or worn brake pads as
soon as possible.

■High Beam Headlight
1Headlight Bulbs
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
heavy items in the trunk or tow a trailer, have the
aiming readjusted at a dealer or by a qualified
technician.
The HB3 and HB4 types are halogen bulbs.
When replacing a 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
denatured alcohol and a clean cloth.
The exterior lights' inside lenses (headlights, brake
lamps, etc.) may fog temporarily after a vehicle wash
or while driving in the rain. This does not impact the
exterior light function.
However, if you see a large amount of water or ice
accumulated inside the lenses, have your vehicle
inspected by a dealer.
