CVT fluid : Refer to TM-288, "General Specification".

Fluid capacity : Refer to TM-288, "General Specification".

CAUTION:

  1. Select “Data Monitor” in “TRANSMISSION” using CONSULT.
  2. Select “FLUID TEMP” and confirm that the CVT fluid temperature is 40°C (104°F) or less.
  3. Check that the selector lever is in the “P” position, then completely engage the parking brake.
  4. Lift up the vehicle.
  5. Remove the drain plug and overflow tube and drain the CVT fluid from the oil pan. TM-266, "Exploded View".
  6. Install the charging pipe set (KV311039S0) (A) into the drain hole.

CAUTION:


CAUTION:

Tighten the charging pipe by hand.

  1. Install the ATF changer hose (B) to the charging pipe.

CAUTION:

Press the ATF changer hose all the way onto the charging pipe until it stops.

  1. Fill approximately 3 liter (3-1/8 US qt, 2-5/8 lmp qt) of the CVT fluid.
  2. Remove the ATF changer hose and charging pipe, then install the drain plug.

NOTE:

Perform this work quickly because CVT fluid leaks.

  1. Lift down the vehicle.
  2. Start the engine.
  3. While depressing the brake pedal, shift the selector lever to the entire position from “P” to “L”, and shift it to the “P” position.

NOTE:

Hold the lever at each position for 5 seconds.

  1. Check that the CONSULT “Data monitor” in “FLUID TEMP” is 35°C (95°F) to 45°C (113°F).
  2. Stop the engine.
  3. Lift up the vehicle.
  4. Remove the drain plug, and then drain CVT fluid from oil pan.
  5. Repeat steps 6 to 16 (one time).
  6. Install the overflow tube. Refer to TM-266, "Exploded View".

CAUTION:

Be sure to tighten to the specified torque. If it is not tightened to the specified torque, the tube may be damaged.


  1. Install the charging pipe set (KV311039S0) (A) into the drain hole.

CAUTION:

Tighten the charging pipe by hand.

  1. Install the ATF changer hose (B) to the charging pipe.

  2. Start the engine.
  3. While depressing the brake pedal, shift the selector lever to the entire position from “P” to “L”, and shift it to the “P” position.

NOTE:

Hold the lever at each position for 5 seconds.

  1. Check that the CONSULT “Data monitor” in “FLUID TEMP” is 35°C (95°F) to 45°C (113°F).
  2. Lift up the vehicle.
  3. Remove the drain plug and confirm that the CVT fluid is drained from the overflow tube.

CAUTION:

Perform this work with the vehicle idling.

NOTE:

If the CVT fluid is not drained, refer to “Adjustment” and refill with the CVT fluid.

  1. When the flow of CVT fluid slows to a drip, tighten the drain plug to the specified torque. TM-266, "Exploded View".

CAUTION:

Never reuse drain plug gasket.

  1. Lift down the vehicle.
  2. Select “Work Support” in “TRANSMISSION” using CONSULT.
  3. Select “CONFORM CVTF DETERIORTN”.
  4. Touch “Erase”.
  5. Stop the engine.

Adjustment

CVT fluid : Refer to TM-288, "General Specification".

Fluid capacity : Refer to TM-288, "General Specification".

CAUTION:

  1. Check that the selector lever is in the “P” position, then completely engage the parking brake.
  2. Start the engine.
  3. Adjust the CVT fluid temperature to be approximately 40В°C (104В°F).

NOTE:

The CVT fluid is largely affected by temperature. Therefore be sure to use CONSULT and check the “FLUID TEMP” under “TRANSMISSION” in “Data Monitor” while adjusting.

  1. While depressing the brake pedal, shift the selector lever to the entire position from “P” to “L”, and shift it to the “P” position.

NOTE:

Hold the lever at each position for 5 seconds.

  1. Lift up the vehicle.
  2. Check that there is no CVT fluid leakage.
  3. Remove the drain plug. Refer to TM-266, "Exploded View".
  4. Install the charging pipe set (KV311039S0) (A) into the drain plug hole.

CAUTION:

Tighten the charging pipe by hand.

  1. Install the ATF changer hose (B) to the charging pipe.

CAUTION:


CAUTION:

Press the ATF changer hose all the way onto the charging pipe until it stops.

  1. Fill approximately 0.5 liter (1/2 US qt, 1/2 lmp qt) of the CVT fluid.
  2. Remove the ATF changer hose from the charging pipe, and check that the CVT fluid drains out from the charging pipe. If it does not drain out, perform charging again.

CAUTION:

Perform this work with the vehicle idling.

  1. When the flow of CVT fluid slows to a drip, remove the charging pipe from the oil pan.
  2. Tighten the drain plug to the specified torque. Refer to TM-266, "Exploded View".

CAUTION:

Never reuse drain plug gasket.

  1. Lift down the vehicle.
  2. Stop the engine.
