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. Remove the right-side engine
compartment cover.

NOTICE
If 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.
