Opening the Hood
- Park the vehicle on a level surface, and set the parking brake.
- Pull the hood release handle under the driver’s side lower corner of the dashboard.
- The hood will pop up slightly.
- 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 lever.
- Remove the support rod from the clamp using the grip. Mount the support rod in the hood.

When closing, remove the support rod and stow it in the clamp, then gently lower the hood. Remove your hand at a height of approximately 12 inches (30 cm) and let the hood close.
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.
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.
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.
Engine Compartment Cover
The component parts in the engine compartment are protected by a cover.
You may need to remove the cover when you perform certain maintenance work. Pull up on the engine compartment cover, remove it from the pin holders.

Recommended Engine Oil
Use a genuine engine oil or another commercial engine oil of suitable type and viscosity (for the ambient temperature) as shown in the image that follows.
Oil is a major contributor to your engine’s performance and longevity. If you drive the vehicle with insufficient or deteriorated oil, the engine may fail or be damaged.![2024 Honda Passport Maintenance (4)](https://www.autouserguide.com/wp-content/uploads/2023/12/2024-Honda-Passport-Maintenance-4-300x101.png)
- Formulated to improve fuel economy.
Synthetic oil
You may also use synthetic motor oil if it is labeled with the API Certification Seal and is the specified viscosity grade.
Engine Oil Additives
Your vehicle does not require oil additives. In fact, they may adversely affect the engine performance and durability.
The following seal indicates the oil is energy conserving and that it meets the American Petroleum Institute’s latest requirements.

Oil Check
We recommend that you check the engine oil level every time you refuel.
Park the vehicle on level ground.
Wait approximately three minutes after turning the engine off before you check the oil.

-
Remove the dipstick (orange).
-
Wipe the dipstick with a clean cloth or paper towel.
-
Insert the dipstick back all the way into its hole.
-
Remove the dipstick again, and check the level. It should be between the upper and lower marks. Add oil if necessary.
If the oil level is near or below the lower mark, slowly add oil, being careful not to overfill.
Under certain driving conditions, it is normal for the engine oil level to rise above the upper mark. If you have a concern, consult a dealer for details.
Adding Engine Oil

-
Unscrew and remove the engine oil fill cap.
-
Add oil slowly.
-
Reinstall the engine oil fill cap, and tighten it securely.
- Wait for three minutes and recheck the engine oil dipstick.
Do not fill the engine oil above the upper mark. Overfilling the engine oil may result in leaks and engine damage.
If any oil spills, wipe it away immediately. Spilled oil may damage the engine compartment components.
Changing the Engine Oil and Oil Filter
You must change the engine oil and oil filter regularly in order to maintain the engine’s lubrication. The engine may be damaged if they are not changed regularly.
Change the oil and filter in accordance with the maintenance message on the driver information interface.

-
Remove the drain bolt and washer from the bottom of the engine, and drain the oil into a suitable container.
NOTICE
You may damage the environment if you do not dispose of the oil in a suitable way. If you are changing the oil by yourself, appropriately dispose of the used oil. Put the oil in a sealed container and take it to a recycling center. Do not throw the oil away into a garbage can or onto the ground.
-
Remove the oil filter and dispose of the remaining oil.

You will need a special wrench to replace the oil filter. You can buy this wrench from a dealer.
When installing the new oil filter, follow the instructions supplied with the oil filter.
Reinstall the engine oil fill cap. Start the engine. If the low oil pressure warning appears, turn off the engine, and check your work.
Engine Coolant
Specified coolant: Honda Long Life Antifreeze/Coolant Type 2
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.
Reserve Tank
-
Make sure the engine and radiator are cool.
-
Check the amount of coolant in the reserve tank.
-
If the coolant level is below the MIN mark, add the specified coolant until it reaches the MAX mark.
-
Inspect the cooling system for leaks.

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.
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.
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.
Radiator
![2024 Honda Passport Maintenance 11](https://www.autouserguide.com/wp-content/uploads/2023/12/2024-Honda-Passport-Maintenance-11-300x220.png)
- Make sure the engine and radiator are cool.
- Remove the engine compartment cover. Turn the radiator cap 1/8th turn counter-clockwise and relieve any pressure in the cooling system. Do not push the cap down when turning.
- Push down and turn the radiator cap counter-clockwise to remove it.
- The coolant level should be up to the base of the filler neck. Add coolant if it is low.
- Put the radiator cap back on, and tighten it fully.
