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.

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.

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

Check the fluid level when the engine is at normal operating temperature.1.Park on level ground, and start the engine.
2. Wait until the radiator fan starts and then
turn off the engine.
uPerform step 3 after waiting for about 60
seconds (less than 90 seconds).
3. Remove the dipstick (yellow loop) from the
transmission and wipe it with a clean cloth.
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.

Handling the Unexpected
■ Next thing to do
1.Check that the cooling fan is operating and
stop the engine once the high temperature
indicator goes off.
uIf the cooling fan is not operating,
immediately stop the engine.
2. Once the engine has cooled down, inspect
the coolant level and check the cooling
system components for leaks.
uIf the coolant level in the reserve tank is
low, add coolant until it reaches the MAX mark.
uIf there is no coolant in the reserve tank,
check that the radiator is cool. Cover the
radiator cap with a heavy cloth and open
the cap. If necessary, add coolant up to
the base of the filler neck, and put the
cap back on.
■ Last thing to do
Once the engine has cooled sufficiently, restart it and check the high temperature indicator.
If the high temperature indicator is off, resume driving. If it stays on, contact a dealer for repairs.
1How to Handle Overheating
If the coolant is leaking, contact a dealer for repairs.
Use water as an emergency/temporary measure only.
Have a dealer flush the system with proper antifreeze
as soon as possible.
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.
