Engine Coolant

Park the vehicle on level ground. Check the reserve tank and the coolant level in the
radiator. We recommend Acura Long Life Antifreeze/Coolant Type 2.

Checking the Reserve Tank

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.

Adding Coolant

1. Make sure the engine and radiator are cool.
2. Turn the radiator cap counterclockwise and

relieve any pressure in the coolant system. Do
not push the cap down when turning.

3. Push down and turn the radiator cap

counterclockwise 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.
6. Pour coolant into the reserve tank until it

reaches the MAX mark. Put the cap back on the
reserve tank.

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.

WARNING

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

Transmission Fluid

Park the vehicle on level ground, and check the fluid level when the engine is at 
normal operating temperature. We recommend Acura Automatic Transmission
Fluid ATF DW-1.

Checking and Refilling the Fluid

1. Start the engine.
2. Wait until the radiator fan starts, and then turn

off the engine. Wait for about one minute.

3. Remove the dipstick (yellow loop) from the

transmission and wipe it with a clean cloth.

4. Insert the dipstick all the way back into the

transmission securely, as shown in the image.

5. Remove the dipstick and check the fluid level. It should be between the upper 

and lower marks in the HOT range.

6. If the level is below the lower mark, add fluid into the dipstick hole to bring 

it to the level between the upper and lower marks, and have your vehicle
checked by a dealer immediately.

Do not mix Acura Automatic Transmission Fluid ATF DW-1 with other
transmission fluids.
 Using a transmission fluid other than Acura ATF DW-1 may 
adversely affect the operation and durability of your vehicle’s transmission, and
damage the transmission.
Pour the fluid slowly and carefully so you do not spill any. Clean up any spills 
immediately; they can damage components in the engine compartment.

NOTICE

Window Washer Fluid

Check the amount of window washer fluid using the 
1/2 mark on the reservoir. If the level is low, fill the
washer reservoir.

Do not use engine antifreeze or a vinegar/water solution in the windshield washer
reservoir. Antifreeze can damage your vehicle’s paint. A vinegar/water solution can
damage the windshield washer pump.
