1Engine Coolant
Specified coolant: Honda All Season Antifreeze/Coolant Type 2
3WARNING
Removing the reserve tank cap while the
engine is hot can cause the coolant to spray
out, seriously scalding you.
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.
Always let the engine and radiator cool
down before removing the reserve tank
cap.
Checking the Coolant
β
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.

NOTICE
If temperatures consistently below -30Β°C are
expected, the coolant mixture should be changed to
a higher concentration. Consult your Honda dealer
for details about a suitable coolant mixture.
MAX
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 aluminium 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.
3. Inspect the cooling system for leaks.
MIN
Do not add rust inhibitors or other additives to your
vehicleβs cooling system. They may not be compatible
with the coolant or with the engine components.
