Do not use engine antifreeze or a
vinegar/water solution in the
windshield washer reservoir. Antifreeze
can damage your vehicle's paint, while
a vinegar/water solution can damage
the windshield washer pump. Use only
commercially-available windshield
washer fluid.Automatic Transmission Fluid
The transmission should be drained
and refilled with new fluid when this
service is shown on a maintenance
message on the multi-information
display.
Check the fluid level with the engine
at normal operating temperature.
1. Park the vehicle on level ground.
Start the engine, let it run until the
radiator fan comes on, then shut
off the engine. For accurate
results, wait about 60 seconds (but
no longer than 90 seconds) before
doing step 2.
2. Remove the dipstick (yellow loop)from the transmission, and wipe it
with a clean cloth.

3. Insert the dipstick all the way intothe transmission securely as
shown in the illustration.
4. Remove the dipstick and check the fluid level. It should be between
the upper and lower marks.
5. If the level is below the lowermark, remove the fill plug, then
add the fluid into the fill hole to
bring it to the level between the
upper and lower marks on the
dipstick.
Pour the fluid slowly and carefully
so you do not spill any. Clean up
any spills immediately; it could
damage components in the engine
compartment. Always use Acura ATF-Z1 (automatic
transmission fluid).
Use only Acura ATF-Z1 (automatic
transmission fluid). Do not mix with
other transmission fluids.
Using transmission fluid other than
Acura ATF-Z1 may cause deterioration
in transmission operation and
durability, and could result in damage
to the transmission.
Damage resulting from the use of
transmission fluid other than Acura
ATF-Z1 is not covered by the Acura
new vehicle warranty.
6. Insert the dipstick all the way back
into the transmission securely as
shown in the illustration.
If you are not sure how to add fluid,
contact your dealer.
