STARTING PROCEDURES
Before starting your vehicle, adjust your seat, adjust the
inside and outside mirrors, fasten your seat belt, and if
present, instruct all other occupants to buckle their seat
belts.
WARNING!
•Never leave children alone in a vehicle. Leaving
unattended children in a vehicle is dangerous for a
number of reasons. A child or others could be
seriously or fatally injured. Do not leave the key in
the ignition. A child could operate power win-
dows, other controls, or move the vehicle.
•Do not leave animals or children inside parked
vehicles in hot weather; interior heat buildup may
cause serious injury or death.
Normal Starting
The shift lever must be in the NEUTRAL or PARK
position before you can start the engine. Apply the brakes
before shifting into any driving gear.
NOTE:Normal starting of either a cold or a warm
engine is obtained without pumping or depressing the
accelerator pedal.
Tip Start Feature
Do notpress the accelerator. Turn the ignition switch to
the START position and release it as soon as the starter
engages. The starter motor will continue to run, and it
will disengage automatically when the engine is running.
If the engine fails to start, the starter will disengage
automatically in 10 seconds. If this occurs, turn the
ignition switch to the LOCK position, wait 10 to 15 sec-
onds, then repeat the normal starting procedure.

Extremely Cold Weather (below20°F or29°C)
To ensure reliable starting at these temperatures, use of
an externally powered electric engine block heater (avail-
able from your authorized dealer) is recommended.
If Engine Fails To Start
WARNING!
•Never pour fuel or other flammable liquids into
the throttle body air inlet opening in an attempt to
start the vehicle. This could result in a flash fire
causing serious personal injury.
(Continued)
WARNING! (Continued)
•Do not attempt to push or tow your vehicle to get
it started. Vehicles equipped with an automatic
transmission 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 dis-
charged 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 dan-
gerous if done improperly. Refer to Section 6 of
this manual for proper jump starting procedures
and follow them carefully.
If the engine fails to start after you have followed the
“Normal Starting” or “Extreme Cold Weather” proce-
dures, it may be flooded. To clear any excess fuel, push
the accelerator pedal all the way to the floor and hold it.
Then, turn the ignition switch to the START position and
290 STARTING AND OPERATING
Page 293 of 498

release it as soon as the starter engages. The starter motor
will disengage automatically in 10 seconds. Once this
occurs, release the accelerator pedal, turn the ignition
switch to the LOCK position, wait 10 to 15 seconds, then
repeat the normal starting procedure.
CAUTION!
To prevent damage to the starter, wait 10 to 15 sec-
onds before trying again.
After Starting
The idle speed is automatically controlled on fuel injected
engines and will decrease as the engine warms up.
ENGINE BLOCK HEATER – IF EQUIPPED
The engine block heater warms the engine, 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.Use the heater when temperatures below 0°F (-18°C) are
expected to last for several days.
The block heater must be plugged in at least one hour to
have an adequate warming effect on the coolant.
The engine block heater cord is located:
•3.7L/4.7L Engine — at the front of the engine com-
partment near the radiator cap.
•5.7L Engine — on the left side of the engine compart-
ment and rearward of the power distribution center.
WARNING!
Remember to disconnect the cord before driving.
Damage to the 110-115 volt electrical cord could cause
electrocution.

AUTOMATIC TRANSMISSION
NOTE:Under extreme cold temperatures (-6°F (-21°C)
and when in DRIVE, transmission operation may be
briefly limited to only 2nd gear operation. Normal op-
eration will resume once the transmission temperature
has risen to a suitable level.
CAUTION!
Damage to the transmission may occur if the follow-
ing precautions are not observed:
•Shift into PARK only after the vehicle has come to
a complete stop.
•Shift into or out of REVERSE only after the
vehicle has come to a complete stop and the engine
is at idle speed.
(Continued)
CAUTION! (Continued)
•Do not shift from REVERSE, PARK, or NEUTRAL
into any forward gear when the engine is above
idle speed.
•Before shifting into any gear, make sure your foot
is firmly on the brake pedal.
WARNING!
It is dangerous to move the shift lever out of PARK or
NEUTRAL 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
reverse. 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 foot is
firmly on the brake pedal.
292 STARTING AND OPERATING
Page 295 of 498

Brake/Transmission Interlock System
This system prevents you from moving the shift lever 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 thebrake
pedal first,before moving the shift lever out of PARK.
Gear Ranges
NOTE:After selecting any gear range, wait a moment to
allow the selected gear to engage before accelerating.
This is especially important when the engine is cold. If
there is a need to restart the engine, be sure to cycle the
key to the LOCK position before restarting. Transmission
gear engagement may be delayed after restarting the
engine if the key is not cycled to the LOCK position first.
PARK
This gear 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. Applythe parking brake when leaving the vehicle in this range.
Always apply the parking brake first, then place the shift
lever into the PARK position.
WARNING!
•Never use the PARK position as a substitute for
the parking brake. Always apply the parking
brake fully when parked to guard against vehicle
movement and possible injury or damage.
•It is dangerous to move the shift lever out of PARK
or NEUTRAL 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 reverse. 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.

REVERSE
Use this range only after the vehicle has come to a
complete stop.
NEUTRAL
Shift to 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.
NOTE:Towing the vehicle, coasting, or driving for any
other reason with the shift lever in NEUTRAL can result
in severe transmission damage. Refer to “Recreational
Towing” in Section 5 and “Towing a Disabled Vehicle” in
Section 6 of this manual.
DRIVE
For most city and highway driving.2 (Second)
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 brak-
ing when descending moderately steep grades. To pre-
vent excessive engine speed, do not exceed 45 mph
(72 km/h) in this range.
1 (First)
For driving up very steep hills and for engine braking at
low speeds (25 mph {40 km/h} or less) when going
downhill. To prevent excessive engine speed do not
exceed 25 mph (40 km/h) in this range.
