AUTOMATIC TRANSMISSION
The pointer on the selector indicates the transmis-
sion gear range (selector is illuminated for night
driving). Start the engine with the selector lever in
N (Neutral) or P (Park) position.
NOTE:
When the ignition is in the ON position, the
brake pedal must be pressed to move the
gearshift lever out of P (Park).
Brake Transmission Shift Interlock
System (BTSI)
This system prevents you from moving the gear
shift out of P (Park) and into any gear unless the
brake pedal is pressed. This system is active only
while the ignition switch is in the ON positions.
Always depress the brake pedal first, before
moving the gear selector out of P (Park).

Electronically Controlled Five Speed
Automatic Transmission (4.7L Engine
Only)
This electronically controlled transmission pro-
vides a precise shift schedule. The transmission
electronics are self calibrating; therefore, the first
few shifts on a new vehicle may be somewhat
abrupt. This is a normal condition, and precision
shifts will develop within a couple hundred miles.
Protect Mode - Electronically
Controlled Transmission (4.7L Engine
Only)
This transmission is monitored electronically for
abnormal conditions. If an abnormal condition is
detected, the transmission's electronic controller
will automatically select direct gear (in the Drive
position) or 2nd gear (in the 2 or 1 position). This
feature will allow the vehicle to be driven to the
dealer for service minimizing any damage to the
transmission. Some conditions that will cause the
transmission to use this alternate gear selection
are momentary and the transmission can be reset
to the normal shift program by performing the
following:
• Stop the vehicle and shift into P (Park).
• Turn the ignition key to the OFF position and
then restart the engine.
• Shift into the desire shift range and resume
driving.
NOTE:
Even if the transmission can be reset, it is
recommend that you see your dealer at your
earliest possible convenience. Your dealer has
the proper diagnostic equipment to determine
if the problem could recur. If the transmission
is cannot be reset, dealer service is required.
Gear Ranges
DO NOT race the engine when shifting from P
(Park) or N (Neutral) position into another gear
range.
P (Park)
Supplements the parking brake by locking the
transmission. The engine can be started in this
range. Never use P (Park) while the vehicle is in
motion. Apply the parking brake when leaving the
vehicle in this range. Always apply the parking
brake first, then place the selector in P (Park)
position.
