Then, without shutting off the engine, follow these steps: 1. Flip the handle up and then remove the dipstick and wipe it with a clean rag or paper towel. The automatic transmission dipstick handle with this symbol on it is located in the engine compartment on the passenger's side of the vehicle. See Engine Compartment Overview on page 366 for more information on location. 2. Reinstall it back in all the way, wait three seconds and then pull it back out again. If the dipstick does not go down the tube easily, turn the blade and try again until it is fully inserted in the tube. 3. Check both sides of the dipstick, and read the lower level. The fluid level must be in the COLD area, below the cross-hatched area, for a cold check or in the HOT or cross-hatched area for a hot check. Be sure to keep the dipstick pointed down to get an accurate reading. 4. If the fluid level is in the acceptable range, reinstall the dipstick back in all the way; then flip the handle down to lock the dipstick in place. 377
