After Starting
The idle speed will automatically decrease as the engine
warms up.
CAUTION!
Long periods of engine idling, especially at high
engine speeds can cause excessive exhaust tempera-
tures which can damage your vehicle. Do not leave
your vehicle unattended with the engine running.
ENGINE BLOCK HEATER Ð IF EQUIPPED
The engine block heater warms engine coolant and
permits quicker starts in cold weather. Connect the cord
to a standard 110-115 volt AC electrical outlet with
grounded, three wire extension cord.
Use the heater when temperatures below 0ÉF (-18ÉC) are
expected to last for several days.The engine block heater cord is located:
²6-cylinder engine Ð bundled and fastened to the
injector rail between injectors 1 and 2.
²V-8 engine Ð coiled and strapped to the transmission
filler tube.
WARNING!
Remember to disconnect the cord before driving.
Damage to the 110-115 volt AC electrical cord could
cause electrocution.
178 STARTING AND OPERATING

AUTOMATIC TRANSMISSION
The pointer on the selector indicates the transmission
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).
WARNING!
It is dangerous to shift the selector lever out of ªPº or
ªNº if the engine speed is higher than idle speed. If
your foot is not firmly on the brake pedal, the
vehicle could accelerate quickly forward or in re-
verse. You could lose control of the vehicle and hit
someone or something. Only shift into gear when
the engine is idling normally and when your right
foot is firmly on the brake pedal.

Brake Transmission Shift Interlock System (BTSI)
This vehicle is equipped with a brake transmission shift
interlock system (BTSI) that holds the gearshift lever in
the P (Park) position when the ignition switch is in an
unlocked position. To move the gear selector lever out of
the P (Park) position, the ignition switch must be turned
to the OFF, ON, or START position, the brake pedal and
the button on the front side of the shifter handle must be
depressed.
Electronically Controlled Five Speed Automatic
Transmission (4.7L Engine Only)
This electronically controlled transmission provides 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 (kilometers).
Protect Mode - Electronically Controlled
Transmission (4.7L Engine Only)
This transmission is monitored electronically for abnor-
mal 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:
²Stop the vehicle and shift into P (Park).
²Turn the ignition key to the OFF position and then
restart the engine.
²Shift into the desire shift range and resume driving.
180 STARTING AND OPERATING

²When shifting into P (Park), depress the button on the
shift lever and firmly move the lever all the way
forward until it stops.
²Look at the shift indicator window on the console to
ensure it is in the P (Park) position.
²When engaged in P (Park), you will not be able to
move the shifter rearward without depressing the shift
lever button.
CAUTION!
Before moving the shift lever out of P (Park), you
must turn the ignition from LOCK to ON so steering
wheel and shift lever are released. Otherwise, dam-
age to steering column or shifter could result.
RÐReverse
Use this range only after the vehicle has come to a
complete stop.
NÐNeutral
Shift to N (Neutral) when the vehicle is standing for
prolonged periods with the engine running. The engine
may be started in this range. Set the parking brake if you
must leave the vehicle.
Overdrive
For most city and highway driving. The transmis-
sion contains electronically controlled 4th and 5th
gears (Overdrives) and will automatically shift from D
(Drive) to 4th and 5th gears if the following conditions
are present:
²The transmission selector is in D (Drive).
²The O/D OFF switch has not been activated.
182 STARTING AND OPERATING

Over Temperature Mode
The transmission electronics constantly monitor the
transmission oil temperature. If the transmission gets too
hot, the transmission will change the way it shifts to help
control the condition. This may result in a slightly
different feeling or response during normal operation in
D (Drive) position. If the transmission becomes hot
enough the O/D OFF indicator light and TRANS OVER
TEMP warning light in the instrument cluster may come
on. After the transmission cools down, it will return to
normal operation.
Torque Converter Clutch
A feature designed to improve fuel economy has been
added to the automatic transmission of this vehicle. A
clutch within the torque converter engages automatically
at calibrated speeds. This may result in a slightly differ-
ent feeling or response during normal operation in high
gear. When the vehicle speed drops or during accelera-
tion, the clutch automatically and smoothly disengages.NOTE:
²The torque converter clutch will not engage until the
transmission fluid and engine coolant are warm (usu-
ally after 1±3 miles (1.6±4.8 km) of driving). Because
engine speed is higher when the torque converter
clutch is not engaged, it may seem as if the transmis-
sion is not shifting into ªOverdriveº when cold. This is
considered a normal condition. Pressing the ªO/D
OFFº switch will show that the transmission is able to
shift into and out of ªOverdrive.º
²If the vehicle has not been driven for several days, the
first few seconds of operation after shifting the trans-
mission into gear may seem sluggish. This is due to the
transmission fluid partially draining from the torque
converter into the transmission. This is considered a
normal condition and will not cause damage to the
transmission. The torque converter will refill within 5
seconds of shifting from P (Park) into any other gear
position.

induce a torque interrupt and allow full engagement of
the newly selected position. With the vehicle stationary, it
may be necessary to shift from D (Drive) to R (Reverse)
and back to D (Drive) after shifting. This will allow full
engagement of the newly selected position. Apply a
constant force when shifting the transfer case lever.
4 PART TIME to 4 FULL TIME or 4 FULL TIME to
4 PART TIME
Shifting between 4 PART TIME and 4 FULL TIME can be
made with the vehicle stopped or in motion. If the vehicle
is in motion, shifts can be made up to 55 mph (88 km/h).
With the vehicle in motion, two momentary releases of the
accelerator pedal may be required after shifting. This will
induce a torque interrupt and allow full engagement of
the newly selected position. With the vehicle stationary, it
may be necessary to shift from D (Drive) to R (Reverse)
and back to D (Drive) after shifting. This will allow full
engagement of the newly selected position. Apply a
constant force when shifting the transfer case lever.
4 FULL TIME to 4 LO or 4 LO to 4 FULL TIME
With the vehicle rolling at 2 to 3 mph (3 to 5 km/h), shift
the transmission into N (Neutral). While the vehicle is
coasting at 2 to 3 mph (3 to 5 km/h), shift the transfer
case lever firmly to the desired position. Do not pause in
transfer case N (Neutral).
NOTE:Pausing in transfer case N (Neutral) in vehicles
equipped with an automatic transmission may require
shutting the engine OFF to avoid gear clash while
completing the shift. If difficulty occurs, shift the trans-
mission to N (Neutral), hold foot on brake, and turn the
engine OFF. Make shift to desired mode.
NOTE:Shifting into or out of 4LO is possible with the
vehicle completely stopped, however difficulty may oc-
cur due to the mating clutch teeth not being properly
aligned. Several attempts may be required for clutch
teeth alignment and shift completion to occur. The pre-
ferred method is with the vehicle rolling 2 to 3 mph (3 to
