Engine Air Cleaner/Filter - GMC Yukon Denali 2013 Owner's Manual

6. 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 procedures
described. Consistency (repeatable
readings) is important to maintaining
proper fluid level. If fluid is added, it
may take 15 minutes or longer to
obtain an accurate reading because
of residual fluid draining down the
dipstick tube. If inconsistent
readings persist, check the
transmission breather to be sure it is
clean and not clogged. If readings
are still inconsistent, contact your
dealer.
