Oil Check
We recommend that you check the engine  oil level every time you refuel or you 
charge the High Voltage battery.
Park the vehicle on level ground.
Turn off the power system. You can check  the oil level without the engine having 
run beforehand. If the engine has been ru nning, wait approximately three minutes 
before you check the oil. 1.Remove the dipstick (orange).
2. Wipe the dipstick with a clean cloth or 
paper towel.
3. Insert the dipstick back all the way into its 
hole.
4. Remove the dipstick again, and check the 
level. It should be between the upper and 
lower marks. Add oil if necessary.1Oil Check
If the oil level is near or below the lower mark, slowly 
add oil, being carefu l not to overfill.

uuMaintenance Under the Hood uEngine Coolant
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 coolan t level every time you refuel or you 
charge the High Voltage battery. Check the re serve tank first. If it is completely 
empty, also check the coolant level in  the radiator. Add the engine coolant 
accordingly.
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.
3. Inspect the cooling  system for leaks.
Specified coolant: Honda Long  Life Antifreeze/Coolant Type 2
■Reserve Tank
1Engine Coolant
NOTICE
Genuine Honda engine coolan t is a 50/50 mixture of 
antifreeze and water that can withstand freezing at 
temperatures as low as about −31°F (−35°C). If your 
vehicle is consistently subjected to temperatures 
below this, the concentration of antifreeze in the 
coolant should be  increased. Consult an authorized 
Honda Clarity Plug-In Hybrid dealer for details.
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  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 anti freeze/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.
