340 STARTING AND OPERATING

STARTING PROCEDURES
Before starting your vehicle, adjust your seat, adjust both
inside and outside mirrors, and fasten your seat belt.
The starter should not be operated for more than 15-
second intervals. Waiting a few seconds between such
intervals will protect the starter from overheating.
WARNING!
Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Leaving children in a
vehicle unattended is dangerous for a number of
reasons. A child or others could be seriously or
fatally injured. Children should be warned not to
touch the parking brake, brake pedal or the shift
lever. Do not leave the key fob in or near the vehicle,
or in a location accessible to children, and do not
(Continued)
WARNING!(Continued)
leave a vehicle equipped with Keyless Enter-N-Go™
(if equipped) in the ACC or ON/RUN mode. A child
could operate power windows, other controls, or
move the vehicle.
Normal Starting
Normal starting of either a warm or cold engine is
obtained without pumping or pressing the accelerator
pedal. Turn the key fob to the START position and release
when the engine starts. If the engine fails to start within
10 seconds, turn the key fob to the OFF position, wait five
seconds, then repeat the “Normal Starting” procedure.
Automatic Transmission
Start the engine with the shift lever in the NEUTRAL or
PARK position. Apply the brake before shifting into any
driving range.
342 STARTING AND OPERATING

NOTE: This vehicle is equipped with a transmission
shift interlocking system. The brake pedal must be
pressed to shift out of PARK.
Tip Start Feature
Do notpress the accelerator. Turn the ignition switch
briefly to the START position and release it. The starter
motor will continue to run but will automatically disen-
gage when the engine is running.
Keyless Enter-N-Go™
This feature allows the driver to oper-
ate the ignition switch with the push
of a button, as long as the Remote
Start/Keyless Enter-N-Go™ FOBIK is
in the passenger compartment.
Normal Starting
Using The ENGINE START/STOP Button
1. The transmission must be in PARK or NEUTRAL.
2. Press and hold the brake pedal while pressing the ENGINE START/STOP button once.
3. The system takes over and attempts to start the vehicle. If the vehicle fails to start, the starter will
disengage automatically after 10 seconds.
4. If you wish to stop the cranking of the engine prior to the engine starting, press the button again.
NOTE: Normal starting of either a cold or a warm
engine is obtained without pumping or pressing the
accelerator pedal.

STARTING AND OPERATING 343

To Turn Off The Engine Using ENGINE
START/STOP Button
1. Place the shift lever in PARK, then press and releasethe ENGINE START/STOP button.
2. The ignition switch will return to the OFF position.
3. If the shift lever is not in PARK, the ENGINE START/ STOP button must be held for two seconds and vehicle
speed must be above 5 mph (8 km/h) before the
engine will shut off. The ignition switch position will
remain in the ACC position until the shift lever is in
PARK and the button is pressed twice to the OFF
position. If the shift lever is not in PARK and the
ENGINE START/STOP button is pressed once, the
EVIC (if equipped) will display a “Vehicle Not In
Park” message and the engine will remain running.
Never leave a vehicle out of the PARK position, or it
could roll. NOTE:
If the ignition switch is left in the ACC or RUN
(engine not running) position and the transmission is in

minutes of inactivity and the ignition will switch to the
OFF position.
ENGINE START/STOP Button Functions – With
Driver ’s Foot OFF The Brake Pedal (In PARK Or

344 STARTING AND OPERATING

3. Press the ENGINE START/STOP button a second timeto change the ignition switch to the RUN position
(EVIC displays “RUN”),
4. Press the ENGINE START/STOP button a third time to return the ignition switch to the OFF position (EVIC
displays “OFF”).
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.
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 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.
• 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.

STARTING AND OPERATING 345

WARNING!(Continued)
•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.
If the engine has been flooded, it may start to run, but not
have enough power to continue running when the key
fob is released. If this occurs, continue cranking with the
accelerator pedal pushed all the way to the floor. Release
the accelerator pedal and the key fob 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 is controlled automatically and it will
decrease as the engine warms up.
STOP/START SYSTEM — IF EQUIPPED
The Stop/Start function is developed to save fuel and
reduce emissions. The system will stop the engine auto-
matically during a vehicle stop if the required conditions
are met. Releasing the brake pedal will automatically
re-start the vehicle.
Automatic Mode
The Stop/Start feature is enabled after every normal
customer engine start. It will remain in STOP/START
NOT READY until you drive forward with a vehicle
speed greater than 5 mph (8 km/h). At that time, the
system will go into STOP/START READY and if all other
conditions are met, can go into an STOP/START AUTO
STOP ACTIVE “Autostop” mode.
346 STARTING AND OPERATING

To Activate The Autostop Mode, The Following Must
Occur:
1. The system must be in STOP/START READY state. ASTOP/START READY message will be displayed in
the Electronic Vehicle Information Center (EVIC)
within the Stop/Start section. Refer to “Electronic
Vehicle Information Center (EVIC)” in “Understand-
ing Your Instrument Panel” for further information.
2. The vehicle must be completely stopped.
3. The transmission Gear Selector must be in Drive 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 an Autostop. While in an Autostop, the Climate Controls system may automati-
cally adjust airflow to maintain cabin comfort. Customer
settings will be maintained upon return to an engine
running condition.
Possible Reasons The Engine Does Not AUTO

safety and comfort conditions to see if they are fulfilled.
In following situations the engine will not stop:
•
Driver ’s seat belt is not buckled
• Driver ’s door is not closed
• Outside temperature is less than 1°F (–17°C) or greater
than 104°F (40°C)
• The vehicle is on a steep grade
• Cabin heating or cooling is in process and an accept-
able cabin temperature has not been achieved
