Engine Coolant

Main

ce

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. 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

■

Checking the Coolant

1

Engine Coolant

NOTICE

Genuine Honda engine coolant 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 a 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 antifreeze/coolant as soon as 
possible.

3

WARNING

Removing the reserve tank 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 reserve tank 
cap.

If Honda MTF is not available, you may use the API 
certificated SAE 0 W-20 or 5 W-20 viscosity motor oil 
as a temporary measure.
Replace with MTF as soon as possible. Motor oil does 
not contain the proper additives for the transmission

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 cargo area, have the aiming 
readjusted at a dealer or by a qualified technician.

When replacing a halogen 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.

Headlights are LED type. Have an authorized Honda 
dealer inspect and replace the light assembly.
