- Start the engine and operate the vehicle for 15 minutes or until the transmission fluid reaches an operating temperature of 82-93°C (180-200°F).
- Park the vehicle on a level surface.
- With your foot on the brake, move the shift lever through each gear range. Pause for about three seconds in each range, ending in Park.

- Remove the transmission fluid level indicator, wipe the indicator clean, and reinsert the indicator. Give the indicator a full twist to close.
- Wait three seconds and remove the indicator.
- Read both sides of the indicator. The fluid must be within the hot cross-hatched area using the lowest level reading.
Notice: Applying the brake pedal during this procedure will affect the fluid level reading.
