MAINTENANCE

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 specifi ed coolant until it reaches the MAX
mark.
3. Inspect the cooling system for leaks.
NOTICE
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.
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
fi ller 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.
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
Pour the fl uid slowly and carefully so you do not spill any. Clean up any spills
immediately; they can damage components in the engine compartment.

Transmission Fluid

Park the vehicle on level ground, and check the fl uid 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 fl uid level. It should be between the upper
and lower marks in the HOT range.
6. If the level is below the lower mark, add fl uid 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.
NOTICE
Do not mix Acura Automatic Transmission Fluid ATF DW-1 with other
transmission fl uids. Using a transmission fl uid other than Acura ATF DW-1 may
adversely affect the operation and durability of your vehicle's transmission, and
damage the transmission.
Pour the fl uid slowly and carefully so you do not spill any. Clean up any spills
immediately; they can damage components in the engine compartment.

Window Washer Fluid

Check the amount of window washer fl uid using the
1/2 mark on the reservoir. If the level is low, fi ll the
washer reservoir.
NOTICE
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.
