STARTING AND OPERATING87
IF ENGINE FAILS TO START
If the engine fails to start after you have followed
the "Normal Starting" procedure and has not
experienced an extended park condition as
previously defined, it may be flooded. Push the
accelerator pedal all the way to the floor and hold
it there. Crank the engine for no more than 10
seconds. This should clear any excess fuel in case
the engine is flooded. Leave the ignition key in the
ON/RUN position, release the accelerator pedal
and repeat the “Normal Starting” procedure.
COLD WEATHER OPERATION
(B
ELOW –22°F OR −30°C)
To ensure reliable starting at these temperatures,
use of an externally powered electric engine block
heater (available from an authorized dealer) is
recommended.
AFTER STARTING
The idle speed is controlled automatically, and it
will decrease as the engine warms up.
ENGINE BREAK-IN RECOMMENDATIONS —
3.6L & 5.7L
A long break-in period is not required for the
drivetrain (engine, transmission, clutch, and rear
axle) in your new vehicle.
Drive moderately during the first 300 miles
(500 km). After the initial 60 miles (100 km),
speeds up to 50 or 55 mph (80 or 90 km/h) are
desirable. While cruising, brief full-throttle acceleration within
the limits of local traffic laws contributes to a good
break-in. However, wide-open throttle acceleration
in low gear can be detrimental and should be
avoided.
The engine oil, transmission fluid, and axle
lubricant installed at the factory is high-quality and
energy-conserving. Oil, fluid, and lubricant changes
should be consistent with anticipated climate and
conditions under which vehicle operations will
occur. For the recommended viscosity and quality
grades Ú
page 291.
NOTE:A new engine may consume some oil during its first
few thousand miles (kilometers) of operation. This
should be considered a normal part of the break-in
and not interpreted as an indication of difficulty.
Please check your oil level with the engine oil indi -
cator often during the break in period. Add oil as
required.
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.
Do not attempt to push or tow your vehicle to
get it started. Vehicles equipped with an auto -
matic 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 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 Ú page 225.
CAUTION!
To prevent damage to the starter, do not
continuously crank the engine for more than 10
seconds at a time. Wait 10 to 15 seconds before
trying again.
CAUTION!
Never use Non-Detergent Oil or Straight Mineral
Oil in the engine or damage may result.

AUTOMATIC TRANSMISSION
You must press and hold the brake pedal while
shifting out of PARK.
CAUTION!
If the Brake Warning Light remains on with the
parking brake released, a brake system
malfunction is indicated. Have the brake system
serviced by an authorized dealer immediately.
WARNING!
Never use the PARK position as a substitute
for the parking brake. Always apply the
parking brake fully when exiting the vehicle to
guard against vehicle movement and possible
injury or damage.
Your vehicle could move and injure you and
others if it is not in PARK. Check by trying to
move the transmission gear selector out of
PARK with the brake pedal released. Make
sure the transmission is in PARK before
exiting the vehicle.
The transmission may not engage PARK if the
vehicle is moving. Always bring the vehicle to a
complete stop before shifting to PARK, and
verify that the transmission gear position indi
-
cator solidly indicates PARK (P) without
blinking. Ensure that the vehicle is completely
stopped, and the PARK position is properly
indicated, before exiting the vehicle.
It is dangerous to shift out of PARK or
NEUTRAL if the engine speed is higher than
idle speed. If your foot is not firmly pressing
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 your foot is firmly
pressing the brake pedal.
Unintended movement of a vehicle could
injure those in or near the vehicle. As with all
vehicles, you should never exit a vehicle while
the engine is running. Before exiting a vehicle,
always come to a complete stop, then apply
the parking brake, shift the transmission into
PARK, and turn the ignition OFF. When the
ignition is in the OFF position, the transmis -
sion is locked in PARK, securing the vehicle
against unwanted movement.
WARNING!
When exiting the vehicle, always make sure
the ignition is in the OFF position, remove the
key fob from the vehicle, and lock the vehicle.
Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Allowing chil -
dren to be 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 transmis -
sion gear selector.
Do not leave the key fob in or near the vehicle
(or in a location accessible to children), and do
not leave the ignition in the ACC or ON/RUN
position. A child could operate power
windows, other controls, or move the vehicle.
CAUTION!
Shift into or out of PARK or REVERSE only after
the vehicle has come to a complete stop.
Do not shift between PARK, REVERSE,
NEUTRAL, or DRIVE when the engine is above
idle speed.
Before shifting into any gear, make sure your
foot is firmly pressing the brake pedal.
WARNING!

90STARTING AND OPERATING
IGNITION PARK INTERLOCK
This vehicle is equipped with an Ignition Park
Interlock which requires the transmission to be in
PARK before the ignition can be turned to the OFF
position. This helps the driver avoid inadvertently
leaving the vehicle without placing the
transmission in PARK. This system also locks the
transmission in PARK whenever the ignition is in
the OFF position.
NOTE:The transmission is NOT locked in PARK when the
ignition is in the ACC position (even though the
engine will be off). Ensure that the transmission is
in PARK, and the ignition is OFF (not in ACC
position) before exiting the vehicle.
BRAKE TRANSMISSION SHIFT
I
NTERLOCK (BTSI) SYSTEM
This vehicle is equipped with a BTSI that holds the
transmission gear selector in PARK unless the
brakes are applied. To shift the transmission out of
PARK, the engine must be running and the brake
pedal must be pressed. The brake pedal must also
be pressed to shift from NEUTRAL into DRIVE or
REVERSE when the vehicle is stopped or moving at
low speeds.
8-SPEED AUTOMATIC TRANSMISSION
The transmission gear range is displayed both on
the gear selector and in the instrument cluster. To
select a gear range, push the lock button on the
gear selector and move the selector rearward or
forward. To shift the transmission out of PARK, the
engine must be running and the brake pedal must
be pressed. You must also press the brake pedal to
shift from NEUTRAL into DRIVE or REVERSE when
the vehicle is stopped or moving at low speeds.
Select the DRIVE range for normal driving.
NOTE:
The transmission electronics are self-cali -
brating; 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 (kilome -
ters).
In the event of a mismatch between the gear
selector position and the actual transmission
gear (for example, driver selects PARK while
driving), the position indicator will blink continu -
ously until the selector is returned to the proper
position, or the requested shift can be
completed. The electronically-controlled transmission adapts
its shift schedule based on driver inputs, along
with environmental and road conditions.
Only shift from DRIVE to PARK or REVERSE when
the accelerator pedal is released and the vehicle is
stopped. Be sure to keep your foot on the brake
pedal when shifting between these gears.
The transmission gear selector provides PARK,
REVERSE, NEUTRAL, DRIVE, and MANUAL
(AutoStick) shift positions. Manual shifts can be
made using the AutoStick shift control. Toggling
the gear selector forward (-) or rearward (+) while
in the MANUAL (AutoStick) position (beside the
DRIVE position) will manually select the
transmission gear, and will display the current gear
in the instrument cluster Ú
page 92.
Automatic Transmission Gear Selector
22_LD_OM_EN_USC_t.book Page 90
92STARTING AND OPERATING
DRIVE (D)
This range should be used for most city and
highway driving. It provides the smoothest upshifts
and downshifts, and the best fuel economy. The
transmission automatically upshifts through all
forward gears. The DRIVE position provides
optimum driving characteristics under all normal
operating conditions.
When frequent transmission shifting occurs (such
as when operating the vehicle under heavy loading
conditions, in hilly terrain, traveling into strong
head winds, or while towing a heavy trailer), use
the AutoStick shift control (if equipped) to select a
lower gear Úpage 92. Under these conditions,
using a lower gear will improve performance and
extend transmission life by reducing excessive
shifting and heat buildup.
During extremely cold temperatures (-22°F
[-30°C] or below), transmission operation may be
modified depending on engine and transmission
temperature as well as vehicle speed. Normal
operation will resume once the transmission
temperature has risen to a suitable level.
MANUAL (M)
The MANUAL (M, +/-) position (beside the DRIVE
position) enables full manual control of
transmission shifting (also known as AutoStick
mode) Ú page 92. Toggling the gear selector
forward (-) or rearward (+) while in the MANUAL (AutoStick) position will manually select the
transmission gear, and will display the current gear
in the instrument cluster as M1, M2, M3, etc.
Transmission Limp Home Mode
Transmission function is monitored electronically
for abnormal conditions. If a condition is detected
that could result in transmission damage,
Transmission Limp Home Mode is activated. In this
mode, the transmission may operate only in
certain gears, or may not shift at all. Vehicle
performance may be severely degraded and the
engine may stall. In some situations, the
transmission may not re-engage if the engine is
turned off and restarted. The Malfunction Indicator
Light (MIL) may be illuminated. A message in the
instrument cluster will inform the driver of the
more serious conditions, and indicate what actions
may be necessary.
In the event of a momentary problem, the
transmission can be reset to regain all forward
gears by performing the following steps:
NOTE:In cases where the instrument cluster message
indicates the transmission may not re-engage after
engine shutdown, perform this procedure only in a
desired location (preferably, at an authorized
dealer).
1. Stop the vehicle.
2. Shift the transmission into PARK, if possible. If
not, shift the transmission to NEUTRAL.
3. Push and hold the ignition switch until the engine turns off.
4. Wait approximately 30 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the problem is no longer detected, the
transmission will return to normal operation.
NOTE:Even if the transmission can be reset, we
recommend that you visit an authorized dealer at
your earliest possible convenience. An authorized
dealer has diagnostic equipment to assess the
condition of your transmission. If the transmission
cannot be reset, authorized dealer service is
required.
AutoStick — If Equipped
AutoStick is a driver-interactive transmission
feature providing manual shift control, giving you
more control of the vehicle. AutoStick allows you to
maximize engine braking, eliminate undesirable
upshifts and downshifts, and improve overall
vehicle performance. This system can also provide
you with more control during passing, city driving,
cold slippery conditions, mountain driving, trailer
towing, and many other situations.
22_LD_OM_EN_USC_t.book Page 92
STARTING AND OPERATING93
Operation
In AutoStick mode, you can use the gear selector
(in the MANUAL position), or the shift paddles to
the MANUAL (M) position (beside the DRIVE (D)
position), or tap one of the shift paddles on the
steering wheel. Tapping the (-) shift paddle to enter
AutoStick mode will downshift the transmission to
the next lower gear, while tapping (+) to enter
AutoStick mode will retain the current gear. The
current transmission gear will be displayed in the
instrument cluster.
Paddle Shifters
NOTE:
Tapping one of the steering wheel-mounted
shift paddles (+/-), if equipped, while the gear
selector is in DRIVE, will activate a temporary
AutoStick mode. Tapping (-) to enter AutoStick
mode will downshift the transmission to the next
lower gear, while tapping (+) to enter AutoStick
mode will retain the current gear. The current
gear will be displayed in the instrument cluster,
but the “M” will not be highlighted. The trans -
mission will revert back to normal operation (if
the gear selector remains in DRIVE) after a
period of time, depending on accelerator pedal
activity.
In some models, the shift paddles may be
disabled (or re-enabled, as desired) using Drive
Mode Set-Up, accessed by selecting Perfor -
mance Control.
In AutoStick mode, the transmission will shift up or
down when (+/-) is manually selected by the driver
(using the gear selector, or the shift paddles [if
equipped]), unless an engine lugging or overspeed
condition would result. It will remain in the selected
gear until another upshift or downshift is chosen,
except as described below.
If normal AutoStick mode is engaged (gear
selector in MANUAL position), manual gear
selection will be maintained until the gear
selector is returned to DRIVE, or as described
below. The transmission will not upshift auto -matically at redline in this mode, nor will down
-
shifts be obtained if the accelerator pedal is
pressed to the floor.
The transmission will automatically downshift
as the vehicle slows (to prevent engine lugging)
and will display the current gear.
The transmission will automatically downshift to
FIRST gear when coming to a stop. After a stop,
the driver should manually upshift (+) the trans -
mission as the vehicle is accelerated.
You can start out, from a stop, in FIRST or
SECOND gear. Tapping (+) (at a stop) will allow
starting in SECOND gear. Starting out in
SECOND gear can be helpful in snowy or icy
conditions.
If a requested downshift would cause the
engine to over-speed, that shift will not occur.
The system will ignore attempts to upshift at too
low of a vehicle speed and an indication will
display.
Holding the (-) paddle pressed (if equipped), or
holding the gear selector in the (-) position, will
downshift the transmission to the lowest gear
possible at the current speed.
Transmission shifting will be more noticeable
when AutoStick is enabled.
The system may revert to automatic shift mode
if a fault or overheat condition is detected.

94STARTING AND OPERATING
To disengage AutoStick mode, return the gear
selector to the DRIVE position, or press and hold
the (+) shift paddle (if equipped, and the gear
selector is already in DRIVE) until “D” is once again
indicated in the instrument cluster. You can shift in
or out of the AutoStick mode at any time without
taking your foot off the accelerator pedal.
SPORT MODE — WITHOUT PERFORMANCE
CONTROL
Your vehicle is equipped with a SPORT Mode
feature. This mode is a configuration set up for
typical enthusiast driving. The engine,
transmission, and steering systems are all set to
their SPORT settings. SPORT Mode will provide
improved throttle response and modified shifting
for an enhanced driving experience, as well the
greatest amount of steering feel. This mode may
be activated and deactivated by pushing the Sport
button on the instrument panel switch bank. For vehicles equipped with Drive Modes or a
“SUPER TRACK PAK” button, refer to “Drive Modes
Supplement” for further information.
FUEL SAVER TECHNOLOGY 5.7L ONLY—
IF EQUIPPED
This feature offers improved fuel economy by
shutting off four of the engine's eight cylinders
during light load and cruise conditions. The system
is automatic with no driver inputs or additional
driving skills required.
NOTE:This system may take some time to return to full
functionality after a battery disconnect.
ELECTRIC POWER STEERING
The Electric Power Steering system provides
increased vehicle response and ease of
maneuverability. The system adapts to different
driving conditions. If the electric steering system
experiences a fault that prevents it from providing
assist, you will still have the ability to steer the
vehicle manually.
If the Electric Power Steering Fault Warning Light is
displayed and the “SERVICE POWER STEERING” or
the “POWER STEERING ASSIST OFF – SERVICE
SYSTEM” message is displayed within the
instrument cluster display, this indicates the
vehicle needs to be taken to the dealer for service
Ú
page 75.
NOTE:
Even if the power steering assistance is no
longer operational, it is still possible to steer the
vehicle. Under these conditions there will be a
substantial increase in steering effort, espe -
cially at low speeds and during parking maneu -
vers.
If the condition persists, see an authorized
dealer for service.
If the Electric Power Steering Fault Warning Light is
displayed and the “POWER STEERING SYSTEM
OVER TEMP” message is displayed on the
instrument cluster screen, they indicate that
extreme steering maneuvers may have occurred
which caused an over temperature condition in the
power steering system. Once driving conditions are
safe, pull over and let the vehicle idle for a few
moments until the Electric Power Steering Fault
Warning Light and message turn off.
WARNING!
Do not downshift for additional engine braking
on a slippery surface. The drive wheels could
lose their grip and the vehicle could skid,
causing a collision or personal injury.
WARNING!
Continued operation with reduced assist could
pose a safety risk to yourself and others. Service
should be obtained as soon as possible.

TOWING TIPS
Before towing, practice turning, stopping, and
backing up the trailer in an area located away from
heavy traffic.
Automatic Transmission
Select the DRIVE range when towing. The
transmission controls include a drive strategy to
avoid frequent shifting when towing. However, if
frequent shifting does occur while in DRIVE, you
can use the AutoStick shift control to manually
select a lower gear.
NOTE:Using a lower gear while operating the vehicle
under heavy loading conditions will improve perfor
-
mance and extend transmission life by reducing
excessive shifting and heat buildup. This action will
also provide better engine braking.
Cruise Control — If Equipped
Do not use on hilly terrain or with heavy loads.
When using the Cruise Control, if you experience
speed drops greater than 10 mph (16 km/h),
disengage until you can get back to cruising
