Upshifts when accelerating (recommended for best fuel economy)
Progressive Range Selection
Progressive Range Selection gives you the
ability to lockout gears from the automatic
shifting range. This may provide you with
an improved driving experience (for
example, in slippery conditions or when
experiencing a steep grade).
With the transmission in drive (D), press
the – button to active PRS. The available
and selected gears are indicated on the
instrument cluster.
All available gears display with the current
gear indicated. Press the – button again
to lock out gears beginning with the highest
gear. Only the available gears display and
the transmission automatically shifts
between the available gears. Press the +
button to unlock gears to allow the
transmission to shift to higher gears. The
transmission shifts automatically within
the gear range you select.
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.

WARNINGS
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 moving the
gearshift lever from park (P) when the
ignition is in the on position and the brake
pedal is not pressed.
If you cannot move the gearshift lever out
of park (P) position with the ignition in the
on position 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 309).
If the fuse is not blown and the brake
lamps are working properly, the following
procedure will allow you to move the
gearshift lever from park (P):
Column-shifter
1. Apply the parking brake and switch off
your vehicle.
2. Move the steering column to the full
down and full rearward position
(toward the driver's seat).
3. Remove the gearshift lever boot.
