Cycle the ignition switch to the START position and
release when the engine starts. If the engine fails to start
within 10 seconds, cycle the ignition switch to the
LOCK/OFF position, wait 10 to 15 seconds, then repeat
the “Normal Starting” procedure.
Tip Start Feature
Cycle the ignition switch to START position and release it
as soon as the starter engages. The starter motor will
continue to run, but will automatically disengage itself
when the engine is running. If the engine fails to start, the
starter will disengage automatically in 10 seconds. If this
occurs, cycle the ignition switch to the LOCK position,
wait 10 to 15 seconds, then repeat the “Normal Starting”
procedure.
Extreme Cold Weather (Below –20°F Or−29°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.
Extended Park Starting
NOTE:Extended Park condition occurs when the vehicle
has not been started or driven for at least 35 days.
1. Install a battery charger or jumper cables to the battery
to ensure a full battery charge during the crank cycle.
2. Cycle the ignition in the START position and release it
when the engine starts.
3. If the engine fails to start within ten seconds, cycle the
ignition to the STOP (OFF/LOCK) position, wait five
seconds to allow the starter to cool, then repeat the
Extended Park Starting procedure.
4. If the engine fails to start after eight attempts, allow
the starter to cool for at least 10 minutes, then repeat
the procedure.

throttle body air inlet opening in an attempt to start
the vehicle. This could result in 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 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. Refer
to “Jump Starting” in “What To Do In Emergen-
cies” for further information.
474 STARTING AND OPERATING

With Tip Start
If the engine fails to start after you have followed the
#Normal Starting#, “Extreme Cold Weather#and#Ex-
tended Park Starting#procedures, it may be flooded. To
clear any excess fuel, press the accelerator pedal all the
way to the floor and hold it. Then, cycle the ignition
switch to the START position and release it as soon as the
starter engages. The starter motor will disengage auto-
matically in 10 seconds. Once this occurs, release the
accelerator pedal, cycle the ignition to the LOCK posi-
tion, wait 10 to 15 seconds, then repeat the “Normal
Starting” procedure.
CAUTION!
To prevent damage to the starter, wait 10 to 15
seconds before trying again.
After Starting
The idle speed is controlled automatically and it will
decrease as the engine warms up.
STOP/START SYSTEM — 3.2L ENGINE
The Stop/Start function is developed to reduce emis-
sions. The system will stop the engine automatically
during a vehicle stop if the required conditions are met.
Releasing the brake pedal or pressing the accelerator
pedal will automatically re-start the engine.
Automatic Mode
The Stop/Start feature is enabled after every normal
customer engine start. At that time, the system will go
into STOP/START READY and if all other conditions are
met, can go into a STOP/START AUTOSTOP ACTIVE
“Autostop” mode.

STARTING AND OPERATING 475

To Activate The Autostop Mode, The Following Must
Occur:
•The system must be in STOP/START READY state. A
STOP/START READY message will be displayed in
the Electronic Vehicle Information Center (EVIC) or
Driver Information Display (DID) within the Stop/
Start section. Refer to “Electronic Vehicle Information
Center (EVIC)” or “Driver Information Display (DID)”
in “Understanding Your Instrument Panel” for further
information.
•The vehicle must be completely stopped.
•The shifter must be in a forward gear and the brake
pedal depressed.
The engine will shut down, the tachometer will move to
the zero position and the Stop/Start telltale will illumi-
nate indicating you are in Autostop. Customer settings
will be maintained upon return to an engine running
condition.
Possible Reasons The Engine Does Not
AUTOSTOP
Prior to engine shut down, the system will check many
safety and comfort conditions to see if they are fulfilled.
