If a preset button is activated while in the PTY (Program 
Type) mode, the PTY mode will be exited and the radio
will tune to the preset station. 
NOTE: If you have selected a PTY with the tune knob, 
simply pressing the tune button in will go directly to a
“PTY seek”.
Button s1-6 (Radio Mode)
These buttons tune the Radio to the stations that you 
commit to push-button memory {12 AM, 12 FM, and 12
Satellite (if equipped) stations}.
Operating Instructions — Tape Player
Insert the cassette with the exposed tape side toward the
left and the mechanical action of the player will gently
pull the cassette into the play position. 
NOTE: When subjected to extremely cold temperatures, 
the tape mechanism may require a few minutes to warm
up for proper operation. Sometimes poor playback may  be experienced due to a defective cassette tape. Clean and 
demagnetize the tape heads at least twice a year.
Seek Button
Press the SEEK button up for the next selection on the
tape and down to return to the beginning of the current
selection. 
Press the SEEK button up or down to move the track 
number to skip forward or backward 1 to 6 selections.
Press the SEEK button once to move 1 selection, twice to
move 2 selections, etc.
Fast Forward (FF)
Press the FF button up momentarily to advance the tape
in the direction that it is playing. The tape will advance
until the button is pressed again or the end of the tape is
reached. At the end of the tape, the tape will play in the
opposite direction.

Summer Operation
Air conditioned vehicles must be protected with a high 
quality antifreeze coolant during summer to provide
proper corrosion protection and to raise the boiling point
of the coolant for protection against overheating. A 50 %
concentration is recommended. Refer to Recommended
Fluids and Genuine Parts for the proper coolant type. 
When using the air conditioner in extremely heavy traffic 
in hot weather especially when towing a trailer, addi-
tional engine cooling may be required. If this situation is
encountered, operate the transmission in a lower gear to
increase engine RPM, coolant flow and fan speed. When
stopped in heavy traffic, it may be necessary to shift into
NEUTRAL and depress the accelerator slightly for fast
idle operation to increase coolant flow and fan speed. 
NOTE: On models equipped with Diesel engines, the 
idle speed will automatically increase to 1000 rpm at
elevated coolant temperatures to improve engine cooling.  Your air conditioning system is also equipped with an 
automatic recirculation system. When the system senses
a heavy load or high heat conditions, it may use partial
Recirculation A/C mode to provide additional comfort.
Winter Operation
When operating the system during the winter months,
make sure the air intake, located directly in front of the
windshield, is free of ice, slush, snow, or other obstruc-
tions.

TRANSMISSION SHIFTING 
Automatic Transmission with Overdrive
The gear shift selector display, located in the instrument 
panel cluster, indicates the transmission gear range (the
selector is illuminated for night driving). The selector
lever is mounted on the right side of the steering column.
You must depress the brake pedal, to pull the selector
lever out of park (P) position (Brake Interlock System). To
drive, move the selector lever from Park or Neutral to the
desired drive position. Pull the selector lever toward you
when shifting into Reverse, Second, First or Park, or
when shifting out of Park.
Gear Ranges
DO NOT race the engine when shifting from Park or
Neutral position into another gear range. “P” Park 
This gear position supplements the parking brake by
locking the transmission. The engine can be started in
this range. Never use Park while the vehicle is in motion.
Apply the parking brake when leaving the vehicle in this
range. Always apply parking brake first, then place the
selector in Park position. On 4-wheel-drive vehicles be
sure that the transfer case is in a drive position!
WARNING!
Never use Park position on an automatic transmis-
sion as a substitute for the parking brake. Always
apply parking brake fully when parked to guard
against vehicle movement and possible injury or
damage.

WARNING!
Your vehicle could move and injure you and others if 
it is not completely in P (Park). Check by trying to
move the gearshift lever back and forth without first
pulling it toward you after you have set it in P. Make
sure it is in Park before leaving the vehicle.
WARNING!
It is dangerous to shift the selector lever out of “P” or
“N” 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.
“R” Reverse
Use this range only after the vehicle has come to a
complete stop.

        Page 301 of 536

“N” Neutral 
Shift to Neutral when the vehicle is standing for pro-
longed periods with the engine running. The engine may
be started in this range. Set the parking brake if you must
leave the vehicle. 
NOTE: Towing the vehicle, coasting, or driving, with 
the transmission in neutral (N) position, can cause severe
damage to the transmission. 
“D” Drive 
This position provides all forward gears, including 3rd
gear direct and 4th and 5th (if equipped) gear overdrive
(see Overdrive Operation). Use this range for most city
and highway driving. 
“2” Second 
Use this position for driving slowly in heavy city traffic
or on mountain roads where more precise speed control  is desirable. Use it also when climbing long grades, and 
for engine braking when descending moderately steep
grades. 
NOTE: 
Do not exceed maximum engine speed. 
“1” First 
Use this position for driving up very steep hills and for
engine braking at low speeds (20 mph [32 km/h] or less)
when going downhill. 
NOTE:  Do not exceed maximum engine speed.
Overdrive Operation
The overdrive automatic transmission contains an elec- 
tronically controlled fourth and fifth (if equipped) speed
(Overdrive). The transmission will automatically shift
from Drive to Overdrive if the following conditions are
present:
•the transmission selector is in Drive;

        Page 302 of 536

•the engine coolant has reached normal operating tem- 
perature;
•vehicle speed is above approximately 30 mph (48
km/h);
•the “TOW HAUL O/D OFF” switch has not been
activated;
•transmission has reached normal operating tempera-
ture. 
NOTE:  If the vehicle is started in extremely cold tem- 
peratures, the transmission may not shift into Overdrive
and will automatically select the most desirable gear for
operation at this temperature. Normal operation will
resume when the transmission fluid temperature has
risen to a suitable level. Refer also to the Note under
torque converter clutch, later in this section.  If the transmission temperature gets extremely hot, the 
transmission will automatically select the most desirable
gear for operation at this temperature. If the transmission
temperature becomes hot enough the TRANS TEMP light
may illuminate and the transmission may downshift out
of Overdrive until the transmission cools down. After
cooldown, the transmission will resume normal opera-
tion. 
The transmission will downshift from Overdrive to Drive 
if the accelerator pedal is fully depressed at vehicle
speeds above approximately 35 mph (56 km/h).
