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 area 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.
How to Add Fluid
Refer to the Maintenance Schedule to determine what
kind of transmission fluid to use. See Recommended
Fluids and Lubricants on page 6-12.
Add fluid only after checking the transmission fluid while it
is hot. (A cold check is used only as a reference.) If the
fluid level is low, add only enough of the proper fluid to
bring the level up to the HOT area for a hot check. It
doesn’t take much fluid, generally less than one pint
(0.5 L). Don’t overfill.
Notice: We recommend you use only fluid labeled
DEXRON
® -III, because fluid with that label is
made especially for your automatic transmission.
Damage caused by fluid other than DEXRON
® -III is
not covered by your new vehicle warranty.
• After adding fluid, recheck the fluid level as
described under How to Check.
• When the correct fluid level is obtained, push the
dipstick back in all the way; then flip the handle
down to lock the dipstick in place.
