Automatic Transmission
The gear selector must be in the NEUTRAL or PARK
position before you can start the engine. Depress the
brake pedal before shifting into any driving gear.
Normal Starting (Above 32°F / 0°C)
1. Do not depress the accelerator.
2. Turn and hold the ignition key in the START position
and release when engine starts.
3. If engine does not start after 3 seconds, depress the
accelerator lightly (while still cranking the engine).
4. If engine does not start after 15 seconds, turn the
ignition key off.
5. Wait 10 to 15 seconds, and repeat step s1—5.
NOTE: This vehicle is equipped with a transmission
shift interlocking system. The brake pedal must be
depressed to shift out of Park (P). Extremely Cold Weather Starting (Below
20°F /
–29°C)
Follow the same instructions in the “Normal Starting”
procedure.
To insure reliable starting at these temperatures, use of an
externally powered electric engine block heater (available
from your dealer) is recommended.
High Altitude Starting (Above 4,000 ft. / 1 219 m)
Follow the same instructions in the “Normal Starting”
procedure.
To insure reliable starting at these temperatures, use of an
externally powered electric engine block heater (available
from your dealer) is recommended.312 STARTING AND OPERATING

If Engine Fails To Start
If the engine fails to start after you have followed the
“Normal Starting” procedure, it may be flooded. Push
the accelerator pedal all the way to the floor and hold it
there while cranking the engine. This should clear any
excess fuel in case the engine is flooded.
CAUTION!To prevent damage to the starter, do not crank the
engine for more than 15 seconds at a time. Wait 10 to
15 seconds before trying again. WARNING!Never pour fuel or other flammable liquid into the
throttle body air inlet opening in an attempt to start
the vehicle. This could result in flash fire causing
serious personal injury. STARTING AND OPERATING 313

WARNING!Do not attempt to push or tow your vehicle to get it
started. Vehicles equipped with an automatic trans-
mission cannot be started this way. Unburned fuel
could enter the catalytic converter and once the
engine has started, ignite and damage the converter
and vehicle. If the vehicle has a discharged battery,
booster cables may be used to obtain a start from a
booster battery or the battery in another vehicle. This
type of start can be dangerous if done improperly.
See section 6 of this manual for the proper jump
starting procedures and follow them carefully. If the engine has been flooded, it may start to run, but not
have enough power to continue running when the key is
released. If this occurs, continue cranking with the accel-
erator pedal pushed all the way to the floor. Release the
accelerator pedal and the key once the engine is running
smoothly.
If the engine shows no sign of starting after two 15
second periods of cranking with the accelerator pedal
held to the floor, the “Normal Starting” procedure should
be repeated.
After Starting
The idle speed will automatically decrease as the engine
warms up.314 STARTING AND OPERATING

ENGINE BLOCK HEATER — 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 a
grounded, three-wire extension cord.
The engine block heater cord is routed under the hood on
the driver side of the vehicle. It has a removable cap that
is located on the driver side of the Integrated Power
Module.
WARNING!Remember to disconnect the cord before driving.
Damage to the 110-115 volt electrical cord could
cause electrocution. AUTOMATIC TRANSMISSION
CAUTION!Damage to the transmission may occur if the follow-
ing precautions are not observed:

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.
Brake/Transmission Interlock System
This system prevents you from moving the gear shift out
of Park and into any gear unless the brake pedal is
pressed. This system is active only while the ignition
switch is in the ON position. Always depress the brake
pedal first, before moving the gear selector out of PARK. Automatic Transmission Ignition Interlock System
This system prevents the key from being removed unless
the shift lever is in PARK. It also prevents shifting out of
PARK unless the key is in the OFF or ON positions.
NOTE: If a malfunction occurs, the system will trap the
key in the ignition cylinder to warn you that this safety
feature is inoperable. The engine can be started and
stopped but the key cannot be removed until you obtain
service.
Four Speed Automatic Transmission
The 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 few
hundred miles.316 STARTING AND OPERATING

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.
“R” Reverse
Shift into this range only after the vehicle has come to a
complete stop.
“N” Neutral
Engine may be started in this range.
“D” Overdrive
For most city and highway driving, it provides smoothest
upshifts and downshifts and best fuel economy. When
frequent transmission shifting occurs while using the
“D” Overdrive position, such as when operating the vehicle under heavy loading conditions, (i.e. in hilly
terrain, traveling into strong head winds or while towing
heavy trailers), using the “3” position will improve
performance and extend transmission life by reducing
excessive shifting and heat build-up.
“3” Drive
This range eliminates shifts into Overdrive. The transmis-
sion will operate normally in First, Second and Third
while in this range. The “3” position should also be used
when descending steep grades to prevent brake system
distress.
NOTE: Using the “3” range while operating the vehicle
under heavy operating conditions will improve perfor-
mance and extend transmission life by reducing exces-
sive shifting and heat build up.
“L” Low
This range should be used for engine braking when
descending very steep grades. In this range, upshifts will318 STARTING AND OPERATING

occur only to prevent engine overspeed while downshifts
occur earlier than other gear range selections.
NOTE: The vehicle computer will over ride Overdrive
and “3” Drive ranges by changing shift points if the
transmission operating temperature exceeds acceptable
limits. This is done to prevent transmission damage due
to overheating.
PARKING BRAKE
When the parking brake is applied with the ignition
switch on, the brake light in the instrument cluster will
turn on.
NOTE: This light only shows that the parking brake is
applied. It does not show the degree of brake application.
Before leaving the vehicle, make sure that the parking
brake is fully applied and place the gear selector in the
Park position. To release the parking brake, pull out on
the parking brake release located on the left side of the
instrument panel. Parking Brake Release STARTING AND OPERATING 319
