Then, without shutting off the engine, follow these steps:
1. Flip the handle up and then pull out 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 5-12
for more information on location.
2. Push it back in all the way, wait three seconds
and then pull it back out again.
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, push the
dipstick back in all the way; then flip the handle
down to lock the dipstick in place.
Consistency of Readings
Always check the fluid level at least twice using the
procedure described previously. Consistency (repeatable
readings) is important to maintaining proper fluid level.
If inconsistent readings persist, contact your dealer.
