fully apply your regular brakes before you can shift
from PARK (P) with the ignition in RUN.
If you cannot shift out of PARK (P), ease pressure
on the shift lever and push the shift lever all the way
into PARK (P) as you maintain brake application.
Then move the shift lever into another gear. See
Shifting Out of Park (P) on page 130.
