Opening the Hood

1.

Park the vehicle on a level surface, and set 
the parking brake.

2.

Pull the hood release handle under the 
driver’s side lower corner of the dashboard.

u

The hood will pop up slightly.

3.

Push the hood latch lever (located under 
the front edge of the hood to the center) to 
the side and raise the hood. Once you have 
raised the hood slightly, you can release the

4.

Remove the support rod from the clamp 
using the grip. Mount the support rod in 
the hood.

When closing, remove the support rod, and

Opening the Hood

NOTICE

Do not open the hood when the wiper arms are 
raised. The hood will strike the wipers, resulting in 
possible damage to the hood and/or the wipers.

NOTICE

Do not press the engine cover forcibly. This may 
damage the engine cover and component parts.

When closing the hood, check that the hood is 
securely latched.

If the hood latch lever moves stiffly, or if you can 
open the hood without lifting the lever, the latch 
mechanism should be cleaned and lubricated.

Do not open the hood while the Auto Idle Stop 
function is activated.

WARNING

The hood support rod can become very hot 
due to heat from the engine.

To ensure against possible burns, do not 
handle the metal section of the rod: Use 
the foam grip instead.

Engine Coolant

Continued

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 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

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.

WARNING

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.

Using any non-Honda brake fluid can cause corrosion 
and decrease the longevity of the system. Have the 
brake system flushed and refilled with Honda Heavy 
Duty Brake Fluid DOT 3 as soon as possible.

If the brake fluid level is at or below the
