Cooling System
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. 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
1Cooling System
NOTICE
Genuine Honda engine coolan t is a 50/50 mixture of 
antifreeze and water that can withstand freezing at 
temperatures as low as a bout -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 anti freeze/coolant as soon as 
possible.
Do not add rust inhibitors or other additives to your 
vehicle’s cooling system. Th ey may not be compatible 
with the coolant or with the engine components.
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.

Maintenance
1. Make sure the engine and radiator are 
cool.
2. Turn the radiator cap 1/8th turn counter-
clockwise and relieve any pressure in the 
cooling system.
3. Turn the radiator cap counter-clockwise 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.
Transmission Fluid
Have a dealer check the fluid level and replace if necessary.
Do not attempt to check or change  the transmission fluid by yourself.

NOTICE
Pour the fluid slowly and ca refully so you do not spill 
any. Clean up any spills immediately; they can 
damage components in the engine compartment.

NOTICE
Do not mix Honda HEVF-Type 1 with other 
transmission fluids.
Using a transmission fluid  other than Honda HEVF-
Type 1 may adversely affect the operation and 
durability of your vehicle’ s transmission, and damage 
the transmission.
Any damage caused by using a transmission fluid that 
is not equivalent to Honda HEVF-Type 1 is not 
covered by Honda’s new ve hicle limited warranty.

uuCleaning uExterior Care
Maintenance
A good coat of automotive body wax helps protect your vehicle’s paint from the 
elements. Wax will wear off over time  and expose your vehicle’s paint to the 
elements, so reapply as necessary.
If you get gasoline, oil, engine coolant, or  battery fluid on resin-coated parts, they 
may stain or the coating may peel. Prompt ly wipe it away using a soft cloth and 
clean water.
Wipe using a glass cleaner.
Aluminum is susceptible to deterioration caused by salt and other road 
contaminants. When necessary, as early as possible use a sponge and mild detergent 
to wipe away these contaminants. Do no t use a stiff brush or harsh chemicals 
(including some commercial wheel cleaners). These can damage the protective finish 
on aluminum alloy wheels, resulting in corrosion. Depending on the type of finish, 
the wheels also may lo se their luster or appear burn ished. To avoid water stains, 
wipe the wheels dry with a cloth while they are still wet.

Ask a dealer about the corr ect coating material when 
you want to repair the painted surface of the parts
