FORD 2003 Mustang v.4 - Manual (Page 107)

Always set the parking brake fully and make
sure the gearshift is latched in P (Park).
Turn the ignition to the LOCK position and remove
the key whenever you leave your vehicle.
If the parking brake is fully released, but the
brake warning lamp remains illuminated, the
brakes may not be working properly. See your
dealer or a qualified service technician.
Driving with an automatic overdrive
transmission with console gearshift and O/D off
switch
Your transmission is equipped with an adaptive
learning strategy found in the vehicle computer. This
feature is designed to increase durability and
provide consistent shift feel over the life of the
vehicle. A new vehicle or transmission may have firm
and/or soft shifts. This operation is considered
normal and will not affect function or durability of
the transmission. Over time, the adaptive learning
process will fully update transmission operation.
Additionally, whenever the battery is disconnected
or a new battery installed, the strategy must be
relearned.
Your automatic
overdrive transmission
provides fully
automatic operation in
either D (Overdrive) or
with the O/D OFF
switch depressed.
Driving with the
gearshift lever in D
(Overdrive) gives the
best fuel economy for
normal driving
conditions. For manual control, start in 1 (First) and
then shift manually.
