Fluid Level
l.Checking/Changing
CAUTION: while chscking and changing, be sure not to
allow dust and other toreign particles to ent€l inlo the
transmission.
Checking
NOTE: Check the fluid level with the engine at normal
operating temperature (the radiator fan comes on).
'1. Park the vehicle on the level ground. Turn oft the
engrne.
2. Remove the dipstick (yellow loop) from the trans-
mission, and wipe lt with a clean cloth.
NOTE: Check the transmission fluid 50 to 90 sec-
onds after shutting off the engine.
3. Insert the diDstick into the transmission.
DIPSTICK (YELLOW LOOPI
Remove the dipstick and check the fluid level.
should be between the uDDer and lower mark.DIPSTICK
5. lf the level is below the lower mark, add fluid into
the filler hole to bring it to the upper mark. Use
Genuine Honda CW Fluid only.
6. Insert the dipstick into the transmission.

Changing
1. Bring the transmission up to normal operating tem-
perature (the radiator fan comes on) by driving the
vehicle. Park the vehicle on the level ground, and
turn off the engine.
2. Bemove the drain plug, and drain the CVT fluid.
NOTE| lf a cooler flusher is to be used, see page 14-
352 and 14-353.
Reinstall the drain plug with a new sealing washer,
then refill the transmission with Genuine Honda
CVT Fluid to the upper mark on the dipstick.

Pressure Testing
. While testing, be careful of the rot8ling front wheels.
. M8k6 suro lifts, iacks, and satety stands are placed properly lsee section 11.
CAUTION:
. Before testing, be sur. the transmb3ion fluid is fillod to the propor lcvel.. Warm up the engin€ to nolmal operating tsmperature bofore testing. While t€sting, be 3ure not to allow dust and other loreign particles to onler into the transmi$ion.
1. Raise the front of the vehicle, and support it with safety stands (see section 1).
2. Set the parking brake. and block both rear wheels securely.
3. Allow the front wheels to rotate freely.
4. Warm up the engine (the radiator fan comes on), then stop arid connect a tachometer.
5. Connect the special tool to each inspection hole.
TOROUE: 18 N.m (1.8 kgt'm, 13 tbtfr)
GAUTION:
. Connect the oil pressuro gauge !!€curoly, bs sur6 not to allow dust and other foroign particlG3 to ontar the inspsc-tion hole.
. Whon troubleshooting by tho E indicltor light indic.t6 a problam. you mu3t u3e an oil p.essure gluge that moa,sures 4,9(X) kPa (a.90 MPa,50.0 kS cr*,771psi) or more when molsuring driv. pulley pressure and driven pullcypre33ure.
NOTE:
. D.ive pulley pressure may be above 3,430 kPa (3.i8 MPa,35.0 kgf/cmr, 498 psi) wh€n there is a transmission prob-
lem that causes the TCM or PCM to go into the fail-safe mode,. Use a commercially available oil pressure gauge that measures 4,900 kPa {4.90 MPa, 5O.O kgf/cmr, 711 psi) ormore, and the Ay'T Oil Pressure Hose, 2210 mm (07MAJ - PY4011A).
