(e) Using a 10 mm hexagon socket wrench, remove the drain plug and gasket from the transaxle oil (CVT) pan sub-assembly. [*3]

(f) Measure the amount of fluid drained. [*4] HINT: Add the same amount of fluid in step [*6].

(g) Using a 10 mm hexagon socket wrench, temporarily install the gasket and drain plug to the transaxle oil (CVT) pan sub-assembly. [*5] HINT: Reuse the old gasket as the drain plug will be removed again when flushing the CVT fluid.

(h) Add fluid to the refill hole using the same amount of fluid drained in step [*4]. [*6] NOTICE: Use Toyota Genuine CVT fluid FE.

(i) Temporarily install the gasket and refill plug to the continuously variable transaxle assembly. [*7] HINT: Reuse the old gasket as the refill plug will be removed again when flushing the CVT fluid.

(j) Lower the vehicle. [*8]

(k) Start the engine. [*9]

(l) Slowly move the shift lever from P to D, and then back to P (keep the shift lever in each position for approximately 3 seconds). [*10]
