Automatic Transmission Adaptive
Learning
This feature's design is to increase
durability and provide consistent shift feel
over the life of your vehicle. A new vehicle
or transmission may have firm shifts, soft
shifts or both. This operation is normal and
does not affect function or durability of the
transmission. Over time, the adaptive
learning process fully updates transmission
operation. Additionally, whenever you
disconnect the battery or install a new
battery, the system must relearn the
strategy.
Brake-Shift Interlock
WARNINGS
Do not drive your vehicle until you
verify that the brake lamps are
working.
When doing this procedure, you need
to take the transmission out of park
(P) which means your vehicle can
roll freely. To avoid unwanted vehicle
movement, always fully apply the parking
brake prior to doing this procedure. Use
wheels chocks if appropriate. If the parking brake is fully released,
but the brake warning lamp remains
illuminated, the brakes may not be
working properly. Have your vehicle
checked as soon as possible. Your vehicle is equipped with a brake-shift
interlock feature that prevents the
gearshift lever from moving from park (P)
when the ignition is on and the brake pedal
is not pressed.
If you cannot move the gearshift lever out
of park (P) position with the ignition is on
and the brake pedal pressed, a malfunction
may have occurred. It is possible that a
fuse has blown or your vehicle
’s brake
lamps are not operating properly. See
Fuse Specification Chart (page 310). If the fuse is not blown and the brake
lamps are working properly, the following
procedure allows you to move the gearshift
lever from park (P):
1. Apply the parking brake. Switch the
ignition key to 1 (off), then remove the
key.
2. Move the steering column to the full down and full rearward position
(toward the driver ’s seat).
3. Remove the gearshift lever boot.
4. Place fingers into hole where you removed the gearshift lever boot and
pull top half of shroud up and forward
to separate it from the lower half of the
shroud. There is a hinge at the forward
edge of the top shroud. Roll the top
half of the shroud upward on the hinge
point to clear the hazard flasher button,
then pull straight rearward toward the
driver ’s seat to remove.
5. Remove the top half of the shroud.
6. Remove the three fasteners under the column that secure the lower shroud
half to the column. 7.
Pull the lock lever into the full unlocked
position and remove the lower shroud
cover by pulling the lever handle
through the slot in the cover.
8. Apply the brake. Gently lift the override
disk and move the gearshift lever into
neutral (N).
