STARTING PROCEDURES
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.
WARNING!Do not leave animals or children inside parked
vehicles in hot weather; interior heat build up may
cause serious injury or death.
The gear selector must be in the NEUTRAL or PARK
position before you can start the engine. Apply the brakes
before shifting into any driving gear. 2.4L Engine
Normal Starting of either a cold or a warm engine is
obtained without pumping or depressing the accelerator
pedal. Turn the key to the “ START ” position and release
when the engine starts. If the engine has not started
within 3 seconds, slightly depress the accelerator pedal
while continuing to crank. If the engine fails to start
within 15 seconds, turn the key to the “ OFF ” position,
wait 10 to 15 seconds, then repeat the normal starting
procedure.
Cold Weather (Below 0 ° Cor32 ° F) or High Altitude
(Above 4,000 feet at all temperatures). If engine has not
been started within past 3 to 4 hours, slightly depress and
hold the accelerator pedal before attempting to start a
cold engine. Turn the key to the “ START ” position. When
the engine starts, release first the key, then the accelerator
pedal. If the engine fails to start within 15 seconds,
discontinue cranking and return the key to the “ OFF ”
position. Repeat the starting procedure.304 STARTING AND OPERATING

Extremely Cold Weather (below
29 ° Cor
20 ° F). To
insure reliable starting at these temperatures, use of an
externally powered electric engine block heater (available
from your dealer) is recommended.
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. 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.
If Engine Fails to Start
If the engine fails to start after you have followed the
“ NORMAL STARTING ” , “ COLD WEATHER ” or “ HIGH
ALTITUDE ” procedures, 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. STARTING AND OPERATING 305
5

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.
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. Do not overspeed engine.
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 ” , “ COLD
WEATHER ” or “ HIGH ALTITUDE ” procedure should be
repeated. After Starting
The idle speed will automatically decrease as the engine
warms up.
3.3L and 3.8L Engine
Normal Starting of either a cold or a warm engine is
obtained without pumping or depressing the accelerator
pedal. Turn the key to the “ START ” position and release
when the engine starts. If the engine has not started
within 3 seconds, slightly depress the accelerator pedal
while continuing to crank. If the engine fails to start
within 15 seconds, turn the key to the “ OFF ” position,
wait 10 to 15 seconds, then repeat the normal starting
procedure.

CAUTION!To prevent damage to the starter, do not crank the

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 up to 15
seconds with the accelerator pedal pushed all the way to
the floor. Release the accelerator pedal and the key once
the engine is running smoothly. Do not overspeed en-
gine. 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.308 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:
• 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.
• 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. STARTING AND OPERATING 309
5

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.310 STARTING AND OPERATING
