second or fifth gear. If you let the shift lever move in the
direction of the pulling, you may end shifting from first
to fourth or from sixth to third gear.
CAUTION!
Always make sure the vehicle comes to a complete
stop before shifting into REVERSE. Failure to do so
may result in transmission damage.You must always use first gear (or REVERSE) when
starting from a standing position.
Recommended Shift Speeds
To utilize your manual transmission efficiently for fuel
economy, it should be upshifted as listed in recom-
mended shift speed chart.
MANUAL TRANSMISSION RECOMMENDED SHIFT SPEEDS
Engine 1-44-5 5-6
6.2L Supercharged mph2025 42
(km/h) (32)(40) (67)
6.4L mph 2037 48

Earlier upshifts during cruise conditions (relatively
steady speeds) may result in increased fuel economy. Higher upshift speeds may be used to obtain a desired
acceleration rate.

STARTING AND OPERATING 351

1–4 Skip Shift
There are times when you must shift the transmission
directly from first gear to fourth gear instead of from first
gear to second gear. This is to help you get the best
possible fuel economy from your vehicle. This occurs
when the engine coolant (antifreeze) is higher than 106°F
(41°C), vehicle speed is greater than 19 mph (30 km/h)
but less than 21 mph (34 km/h), and the transmission is
in first gear, and the accelerator is at ¼ throttle or less.
After you shift the transmission to fourth gear, you can
press the clutch in and shift to another forward gear.
Downshifting
To maintain a safe speed and prolong brake life, down-
shift to maintain a safe speed when descending a steep
grade.
WARNING!
Skipping more than one gear while downshifting,
could cause you to lose control of your vehicle. You
could have a collision.
CAUTION!
•If you skip more than one gear while downshifting
or downshift at too high an engine speed, you
could damage the engine, transmission, or clutch.
• Do not downshift into first gear when the vehicle is
moving faster than 15 mph (24 km/h), as you could
damage the engine and/or clutch.
352 STARTING AND OPERATING

CAUTION!(Continued)
severe transmission damage. Refer to “Recreational
Towing” in “Starting And Operating” and “Towing A
Disabled Vehicle” in “What To Do In Emergencies”
for further information.
DRIVE (D)
This range should be used for most city and highway
driving. It provides the smoothest upshifts and down-
shifts, and the best fuel economy. The transmission
automatically upshifts through all forward gears. The
DRIVE position provides optimum driving characteris-
tics under all normal operating conditions.
When frequent transmission shifting occurs (such as
when operating the vehicle under heavy loading condi-
tions, in hilly terrain or traveling into strong head winds),
use the AutoStick shift control (refer to AutoStickin this
section for further information) to select a lower gear. 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 depend-
ing 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; refer to
“AutoStick” in this section for further information). Tog-
gling the shift lever 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.
360 STARTING AND OPERATING

•The vehicle will restart with VALET active if VALET
was active when the vehicle was last shut down.
• Eco (Automatic Transmission only) — Eco modifies
the vehicle’s engine and transmission settings to pro-
vide improved fuel economy at a trade-off with accel-
eration performance. Increased engine exhaust noise
and/or vibration may be noticed while Eco is active,
this is normal and will not damage the vehicle.
NOTE: Changing the Drive Mode will deactivate Eco.
Launch Mode — If Equipped
This vehicle is equipped with a Launch Control system
that is designed to allow the driver to achieve maximum
vehicle acceleration in a straight line. Launch Control is a
form of traction control that manages tire slip while
launching the vehicle. This feature is intended for use
during race events on a closed course where consistent quarter mile and zero to sixty times are desired. The
system is not intended to compensate for lack of driver
experience or familiarity with the race track. Use of this
feature in low traction (cold, wet, gravel, etc.) conditions
may results in excess wheel slip outside this systems
control resulting in an aborted launch.
NOTE:
Launch mode is not available within the first 500
miles of engine break-in.
Preconditions:
• Launch control should not be used on public roads.
Always check track conditions and the surrounding
area.
• Launch Control is not available for the first 500 miles
of the vehicle’s life.
• Launch Control should only be used when the engine
and transmission are at operating temperature.
370 STARTING AND OPERATING

WARNING!
Continued operation with reduced power steering
assist could pose a safety risk to yourself and others.
Service should be obtained as soon as possible.
CAUTION!
Prolonged operation of the steering system at the end
of the steering wheel travel will increase the steering
fluid temperature and it should be avoided when
possible. Damage to the power steering pump may
occur.
FUEL SAVER TECHNOLOGY — 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.
PARKING BRAKE
Before leaving the vehicle, make sure that the parking
brake is fully applied and place the shift lever in the
PARK or REVERSE (manual transmission only) position.
When the parking brake is applied and the ignition
switch is in the ON position (RUN position with Keyless
Enter-N-Go™), the “Brake Warning Light” in the instru-
ment cluster will illuminate.
NOTE:
• When the parking brake is applied and the transmis-
sion is placed in gear, the “Brake Warning Light” will
flash. If vehicle speed is detected, a chime will sound
to alert the driver. Fully release the parking brake
before attempting to move the vehicle.
382 STARTING AND OPERATING

WARNING!(Continued)
•Unequal tire pressures can cause steering prob-
lems. You could lose control of your vehicle.
• Unequal tire pressures from one side of the vehicle
to the other can cause the vehicle to drift to the
right or left.
• Always drive with each tire inflated to the recom-
mended cold tire inflation pressure.
Both under-inflation and over-inflation affect the stability
of the vehicle and can produce a feeling of sluggish
response or over responsiveness in the steering.
NOTE:
• Unequal tire pressures from side to side may cause
erratic and unpredictable steering response.
• Unequal tire pressure from side to side may cause the
vehicle to drift left or right.
Fuel Economy
Underinflated tires will increase tire rolling resistance
resulting in higher fuel consumption.
Ride Comfort And Vehicle Stability
Proper tire inflation contributes to a comfortable ride.
Over-inflation produces a jarring and uncomfortable
ride.
Tire Inflation Pressures
The proper cold tire inflation pressure is listed on the
driver’s side B-Pillar or rear edge of the driver’s side
door.
At least once a month:
• Check and adjust tire pressure with a good quality
pocket-type pressure gauge. Do not make a visual

CAUTION!(Continued)
cause the Tire Pressure Monitoring System (TPMS)
sensor to become inoperable. After using an after-
market tire sealant it is recommended that you take
your vehicle to your local dealer to have your
sensor function checked.
• After inspecting or adjusting the tire pressure,
always reinstall the valve stem cap. This will
prevent moisture and dirt from entering the valve
stem, which could damage the TPM sensor.
NOTE:
• The TPMS is not intended to replace normal tire care
and maintenance or to provide warning of a tire failure
or condition.
• The TPMS should not be used as a tire pressure gauge
while adjusting your tire pressure. •
Driving on a significantly under-inflated tire causes
the tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel efficiency and tire
tread life, and may affect the vehicle’s handling and
stopping ability.
• The TPMS is not a substitute for proper tire mainte-
nance, and it is the driver ’s responsibility to maintain
correct tire pressure using an accurate tire pressure
gauge, even if under-inflation has not reached the level
to trigger illumination of the “TPM Telltale Light”.
• Seasonal temperature changes will affect tire pressure,
and the TPMS will monitor the actual tire pressure in
the tire.
Premium System
The Tire Pressure Monitor System (TPMS) uses wireless
technology with wheel rim mounted electronic sensors to

FUEL REQUIREMENTS
6.2L Supercharged And 6.4L Engine
This engine is designed to meet all emis-
sions regulations, provide optimal fuel
economy and performance when using
high-quality unleaded “Premium” gaso-
line having a posted octane number of 91
as specified by the (R+M)/2 method. The use of 91 or
higher octane “Premium” gasoline is required for in this
engine.
While operating on gasoline with the required octane
number, hearing a light knocking sound from the engine
is not a cause for concern. However, if the engine is heard
making a heavy knocking sound, see your dealer imme-
diately. Use of gasoline with a lower than recommended
octane number can cause engine failure and may void or
not be covered by the New Vehicle Limited Warranty. Poor quality gasoline can cause problems such as hard
starting, stalling, and hesitations. If you experience these
symptoms, try another brand of gasoline before consid-
ering service for the vehicle.Reformulated Gasoline
Many areas of the country require the use of cleaner
burning gasoline referred to as “Reformulated Gasoline”.
Reformulated gasoline contain oxygenates and are spe-
cifically blended to reduce vehicle emissions and im-
prove air quality.
The use of reformulated gasoline is recommended. Prop-
erly blended reformulated gasoline will provide im-
proved performance and durability of engine and fuel
system components.
426 STARTING AND OPERATING

Gasoline/Oxygenate Blends
Some fuel suppliers blend unleaded gasoline with oxy-
genates such as ethanol.
CAUTION!
DO NOT use gasoline containing Methanol or gaso-
line containing more than 10% Ethanol. Use of these
blends may result in starting and drivability prob-
lems, damage critical fuel system components, cause
emissions to exceed the applicable standard, and/or
cause the “Malfunction Indicator Light” to illumi-
nate. Please observe pump labels as they should
clearly communicate if a fuel contains greater than
10% ethanol.
Problems that result from using gasoline containing
Methanol or gasoline containing more than 10% ethanol are not the responsibility of the manufacturer and may
void or not be covered under New Vehicle Limited
Warranty.
E-85 Usage In Non-Flex Fuel Vehicles
Non-Flex Fuel Vehicles (FFV) are compatible with gaso-
line containing up to 10% ethanol (E10). Gasoline with
higher ethanol content may void the New Vehicle Lim-
ited Warranty.
If a Non-FFV vehicle is inadvertently fueled with E-85
fuel, the engine will have some or all of these symptoms:
•
Operate in a lean mode.
• OBD II “Malfunction Indicator Light” on.
• Poor engine performance.
• Poor cold start and cold drivability.
• Increased risk for fuel system component corrosion.
