temperatures. This requires transmission fluid changes more frequently than recommended by the 
Maintenance Minder. If you regularly drive your vehicle under these conditions, have the transmission 
fluid changed at 60,000 miles (100,000 km), then every 30,000 miles (48,000 km).

Recommended Engine Oil





Recommended Engine Oil

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.

This seal indicates the oil is energy conserving 
and that it meets the American Petroleum 
Institute’s latest requirements.

Use Genuine Acura Motor Oil or another 
commercial engine oil of suitable viscosity for 
the ambient temperature as shown below.

■

Synthetic oil

You may also use synthetic motor oil if it is labeled with the API Certification Seal 
and is the specified viscosity grade.

• Genuine Acura Motor Oil
• Premium-grade 0W-20 detergent oil with an API Certification Seal on the 

container.

1

Recommended Engine Oil

Engine Oil Additives
Your vehicle does not require oil additives. In fact, 
they may adversely affect the engine performance 
and durability.





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.

1. Remove the dipstick (orange handle).

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.

1

Oil Check

If the oil level is near or below the lower mark, slowly 
add oil being careful not to overfill.

Changing the Engine Oil and Oil Filter

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.

Engine Coolant







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 . Check the amount of coolant in the 

reserve tank.

2. 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

If temperatures consistently below -22°F (-30°C) are 
expected, the coolant mixture should be changed to 
a higher concentration. Consult a dealer for more 
information.

If Honda antifreeze/coolant is not available, you may 
use another major brand 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.

Replacing Light Bulbs

Headlight Bulbs

When replacing, use the following bulbs.

1. Remove the engine coolant reservoir.

2. Remove the fasteners, using a flat-tip 

screwdriver. Remove the cover of the air 
intake duct and its upper part.

High beam headlight: 60 W (HB3 for halogen bulb type)

Low beam headlight:

35 W (D2S for high voltage discharge type)

Headlight Bulbs

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 or tow a trailer, 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.

The exterior lights’ inside lenses (headlights, brake 
lamps, etc.) may fog temporarily after a car wash or 
while driving in the rain. This does not impact the 
exterior light function.
However, if you see a large amount of water or ice 
accumulated inside the lenses, have your vehicle 
inspected by a dealer.
