PERIODIC SAFETY CHECKS YOU SHOULD
M
AKE OUTSIDE THE VEHICLE
Tires
Examine tires for excessive tread wear and
uneven wear patterns. Check for stones, nails,
glass, or other objects lodged in the tread or
sidewall. Inspect the tread for cuts and cracks.
Inspect sidewalls for cuts, cracks, and bulges.
Check the wheel nuts for tightness. Check the
tires (including spare) for proper cold inflation
pressure.
Lights
Have someone observe the operation of brake
lights and exterior lights while you work the
controls. Check turn signal and high beam
indicator lights on the instrument panel.
Door Latches
Check for proper closing, latching, and locking.
Fluid Leaks
Check area under the vehicle after overnight
parking for fuel, coolant, oil, or other fluid leaks.
Also, if gasoline fumes are detected or if fuel, or
brake fluid leaks are suspected, the cause
should be located and corrected immediately.
ONLY use the driver’s side floor mat on the
driver’s side floor area. To check for inter -
ference, with the vehicle properly parked
with the engine off, fully depress the accel -
erator, the brake, and the clutch pedal (if
present) to check for interference. If your
floor mat interferes with the operation of
any pedal, or is not secure to the floor,
remove the floor mat from the vehicle and
place the floor mat in your trunk.
ONLY use the passenger’s side floor mat on
the passenger’s side floor area.
ALWAYS make sure objects cannot fall or
slide into the driver’s side floor area when
the vehicle is moving. Objects can become
trapped under accelerator, brake, or clutch
pedals and could cause a loss of vehicle
control.
WARNING! (Continued)
NEVER place any objects under the floor
mat (e.g., towels, keys, etc.). These objects
could change the position of the floor mat
and may cause interference with the accel -
erator, brake, or clutch pedals.
If the vehicle carpet has been removed and
re-installed, always properly attach carpet
to the floor and check the floor mat
fasteners are secure to the vehicle carpet.
Fully depress each pedal to check for inter -
ference with the accelerator, brake, or
clutch pedals then re-install the floor mats.
It is recommended to only use mild soap
and water to clean your floor mats. After
cleaning, always check your floor mat has
been properly installed and is secured to
your vehicle using the floor mat fasteners
by lightly pulling mat.

152STARTING AND OPERATING
(Continued)
IF ENGINE FAILS TO START
If the engine fails to start after you have
followed the “Normal Starting” or “Cold
Weather Operation” procedure, 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 15 seconds. This should clear
any excess fuel in case the engine is flooded.
Leave the ignition key in the RUN position,
release the accelerator pedal and repeat the
“Normal Starting” procedure.
AFTER STARTING
The idle speed is controlled automatically, and
it will decrease as the engine warms up.
ENGINE BLOCK HEATER — IF EQUIPPED
The engine block heater warms the engine, 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 must be plugged in at
least one hour to have an adequate warming
effect on the engine.
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 near the air box.
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.
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
automatic 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. Refer to
“Jump Starting Procedure” in “In Case Of
Emergency” for further information.
CAUTION!
To prevent damage to the starter, do not
continuously crank the engine for more than
25 seconds at a time. Wait 60 seconds
before trying again.
WARNING!
(Continued)
WARNING!
Remember to disconnect the engine block
heater cord before driving. Damage to the
110-115 Volt electrical cord could cause
electrocution.

20_LA_OM_EN_USC_t.book Page 152

STARTING AND OPERATING153
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 are 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, refer to “Fluids And
Lubricants” in “Technical Specifications”.
NOTE:
A new engine may consume some oil during its
first few thousand miles (kilometers) of opera -
tion. This should be considered a normal part of
the break-in and not interpreted as an indica -
tion of difficulty. Please check your oil level with
the engine oil indicator often during the break in
period. Add oil as required.ENGINE BREAK-IN RECOMMENDATIONS —
6.2L & 6.4L
The following tips will be helpful in obtaining
optimum performance and maximum durability
for your new vehicle.
Despite modern technology and World Class
manufacturing methods, the moving parts of
the vehicle must still wear in with each other.
This wearing in occurs mainly during the first
500 miles (805 km) and continues through the
first oil change interval.
It is recommended for the operator to observe
the following driving behaviors during the new
vehicle break-in period:
0 to 100 miles (0 to 161 km):
Do not allow the engine to operate at idle for
an extended period of time.
Depress the accelerator pedal slowly and not
more than halfway to avoid rapid accelera -
tion.
Avoid aggressive braking.
Drive with the engine speed less than
3,500 RPM.
Maintain vehicle speed below 55 mph
(88 km/h) and observe local speed limits. 100 to 300 miles (161 to 483 km):

Depress the accelerator pedal slowly and not
more than halfway to avoid rapid accelera -
tion in lower gears (FIRST to THIRD gears).
Avoid aggressive braking.
Drive with the engine speed less than
5,000 RPM.
Maintain vehicle speed below 70 mph
(112 km/h) and observe local speed limits.
300 to 500 miles (483 to 805 km) :
Exercise the full engine RPM range, shifting
manually at higher RPM when possible.
Do not perform sustained operation with the
accelerator pedal at wide open throttle.
Maintain vehicle speed below 85 mph
(136 km/h) and observe local speed limits.
For the first 1,500 miles (2,414 km):
Do not participate in track events, sport
driving schools, or similar activities during
the first 1,500 miles (2,414 km).
NOTE:
Check engine oil with every refueling and add if
necessary. Oil and fuel consumption may be
higher through the first oil change interval.
Running the engine with an oil level below the
add mark can cause severe engine damage.
CAUTION!
Never use Non-Detergent Oil or Straight
Mineral Oil in the engine or damage may
result.

STARTING AND OPERATING157
RECOMMENDED SHIFT SPEEDS
To utilize your manual transmission efficiently for fuel economy, it should be upshifted as listed in recommended shift speed chart.
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.
NOTE:
Your vehicle is equipped with a transmission reverse inhibitor system. Always depress the clutch pedal fully to the floor before shifting into REVERSE.
When vehicle speed is greater than 3 mph (5 km/h), the reverse inhibitor activates to help prevent shifts into REVERSE. When at a complete stop,
you may notice lighter shift efforts into REVERSE with the ignition switch in the ON position (RUN position for Keyless Enter-N-Go), as compared to
the ignition LOCK position (OFF position for Keyless Enter-N-Go). This is normal operation of the transmission reverse inhibitor system.
Due to the high performance nature of your drivetrain, you may hear your transmission. This can be most noticeable when the vehicle is idling in
NEUTRAL with the clutch engaged (clutch pedal released), but it may also be heard when driving at low engine RPM. Also, this may be more noticeable
when the transmission is warm. This is a normal condition and is not an indication of a problem with your clutch or transmission.

(Continued)
1–4 SKIP SHIFT
In Auto Drive Mode, Default, or Street Drive
Modes, 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.
NOTE:
The 1 - 4 Skip Shift feature is disabled when
selecting Sport Mode, or when selecting Track
or Custom Drive Modes (SRT only). Refer to the
“Drive Mode Supplement” for further descrip-
tions of these modes.
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,
downshift to maintain a safe speed when
descending a steep grade.
AUTOMATIC TRANSMISSION — IF
EQUIPPED
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 down -
shifting or downshift at too high an engine
speed, you could damage the engine, trans -
mission, 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.
WARNING!
Never use the PARK position as a substi -
tute 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 indicator solidly indicates PARK (P)
without blinking. Ensure that the vehicle is
completely stopped, and the PARK position
is properly indicated, before exiting the
vehicle.

20_LA_OM_EN_USC_t.book Page 158

162STARTING AND OPERATING
The following indicators should be used to
ensure that you have properly engaged the
transmission into the PARK position:
When shifting into PARK, push the lock
button on the gear selector and firmly move
the selector all the way forward until it stops
and is fully seated.
Look at the transmission gear position
display and verify that it indicates the PARK
position (P), and is not blinking.
With the brake pedal released, verify that the
gear selector will not move out of PARK.
REVERSE (R)
This range is for moving the vehicle backward.
Shift into REVERSE only after the vehicle has
come to a complete stop.
NEUTRAL (N)
Use this range when the vehicle is standing for
prolonged periods with the engine running.
Apply the parking brake and shift the
transmission into PARK if you must exit the
vehicle. 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.
Never leave children alone in a vehicle, or
with access to an unlocked vehicle.
Allowing children to be in a vehicle unat
-
tended 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 transmission gear
selector.
Do not leave the key fob in or near the
vehicle (or in a location accessible to chil -
dren), and do not leave the ignition in the
ACC or ON/RUN mode. A child could
operate power windows, other controls, or
move the vehicle.
CAUTION!
Before moving the transmission gear
selector out of PARK, you must start the
engine, and also press the brake pedal.
Otherwise, damage to the gear selector
could result.
DO NOT race the engine when shifting from
PARK or NEUTRAL into another gear range,
as this can damage the drivetrain.
WARNING! (Continued)WARNING!
Do not coast in NEUTRAL and never turn off
the ignition to coast down a hill. These are
unsafe practices that limit your response to
changing traffic or road conditions. You might
lose control of the vehicle and have a
collision.
CAUTION!
Towing the vehicle, coasting, or driving for any
other reason with the transmission in
NEUTRAL can cause severe transmission
damage.
Refer to “Recreational Towing” in “Starting
And Operating” and “Towing A Disabled
Vehicle” in “In Case Of Emergency” for further
information.

20_LA_OM_EN_USC_t.book Page 162

166STARTING AND OPERATING
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.
NOTE:
If equipped with a manual transmission, the
1 - 4 Skip Shift Feature is disabled in SPORT
Mode.
For vehicles equipped with Drive Modes or a
“SUPER TRACK PAK” button, refer to “Drive
Mode Supplement” for further information.
FUEL SAVER TECHNOLOGY 5.7L AND 6.4L
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. When the
system is active, an indication will display within
the instrument cluster “Fuel Economy” main
menu screen. NOTE:
This system may take some time to return to full
functionality after a battery disconnect.
ELECTRIC POWER STEERING
The Electric Power Steering system will give you
good vehicle response and increased ease of
maneuverability in tight spaces. The system will
vary its assist to provide light efforts while
parking and good feel while driving. 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 warning
icon 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. Refer to “Warning Lights And Messages” in
“Getting To Know Your Instrument Panel” for
further information.
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,
especially at low speeds and during parking
maneuvers.
If the condition persists, see an authorized
dealer for service.
If the Steering icon 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 icon and message turn off.
SPEED CONTROL — IF EQUIPPED
When engaged, the Speed Control takes over
accelerator operations at speeds greater than
25 mph (40 km/h) or 20 mph (32 km/h), depending on engine size and axle ratio.
WARNING!
Continued operation with reduced assist
could pose a safety risk to yourself and
others. Service should be obtained as soon
as possible.

REFUELING THE VEHICLE
The gas cap is located behind the fuel filler door
on the left side of the vehicle. Use a finger to
pull open the door. If the gas cap is lost or
damaged, be sure the replacement cap is for
use with this vehicle.
Fuel Filler Cap

NOTE:
When removing the fuel filler cap, lay the cap
tether in the hook, located on the fuel filler door. NOTE:
When the fuel nozzle “clicks” or shuts off, the
fuel tank is full.
Tighten the gas cap until you hear a “clicking”
sound. This is an indication that the gas cap
is tightened properly. The MIL in the instru
-
ment cluster may turn on if the gas cap is not
secured properly. Make sure that the gas cap
is tightened each time the vehicle is refueled.
LOOSE FUEL FILLER CAP MESSAGE
If the vehicle diagnostic system determines that
the fuel filler cap is loose, improperly installed,
or damaged, a ”gASCAP” message will display in
the odometer or a “Check Gascap” message will
display in the instrument cluster. If this occurs,
tighten the fuel filler cap properly and press the
Trip Odometer button to turn off the message. If
the problem continues, the message will appear
the next time the vehicle is started.
WARNING!
Never have any smoking materials lit in or
near the vehicle when the fuel door is open
or the tank is being filled.
Never add fuel when the engine is running.
This is in violation of most state and federal
fire regulations and may cause the
“Malfunction Indicator Light” to turn on.
A fire may result if fuel is pumped into a
portable container that is inside of a
vehicle. You could be burned. Always place
fuel containers on the ground while filling.
CAUTION!
Damage to the fuel system or emissions
control system could result from using an
improper fuel tank filler tube cap.
A poorly fitting fuel filler cap could let impu -
rities into the fuel system.
A poorly fitting fuel filler cap may cause the
“Malfunction Indicator Light (MIL)” to
turn on.
To avoid fuel spillage and overfilling, do not
“top off” the fuel tank after filling. When the
fuel nozzle “clicks” or shuts off, the fuel
tank is full.
CAUTION! (Continued)

20_LA_OM_EN_USC_t.book Page 188

STARTING AND OPERATING189
A loose, improperly installed, or damaged fuel
filler cap may also turn on the MIL.
VEHICLE LOADING
The load carrying capacity of your vehicle is
shown on the “Vehicle Certification Label”. This
information should be used for passenger and
luggage loading as indicated.
Do not exceed the specified Gross Vehicle
Weight Rating (GVWR) or the Gross Axle Weight
Rating (GAWR).
VEHICLE CERTIFICATION LABEL
Your vehicle has a Vehicle Certification Label
affixed to the drivers side B-pillar or the rear of
the driver’s door.
The label contains the following information:
Name of manufacturer
Month and year of manufacture
Gross Vehicle Weight Rating (GVWR)
Gross Axle Weight Rating (GAWR) front
Gross Axle Weight Rating (GAWR) rear
Vehicle Identification Number (VIN)
Type of vehicle
Month, Day, and Hour of manufacture (MDH) The bar code allows a computer scanner to read
the VIN.
GROSS VEHICLE WEIGHT RATING
(GVWR)
The GVWR is the total allowable weight of your
vehicle. This includes driver, passengers, and
cargo. The total load must be limited so that you
do not exceed the GVWR.
GROSS AXLE WEIGHT RATING (GAWR)
The GAWR is the maximum capacity of the front
and rear axles. Distribute the load over the front
and rear axles evenly. Make sure that you do
not exceed either front or rear GAWR.
OVERLOADING
The load carrying components (axle, springs,
tires, wheels, etc.) of your vehicle will provide
satisfactory service as long as you do not
exceed the GVWR and the front and rear GAWR.
The best way to figure out the total weight of
your vehicle is to weigh it when it is fully loaded
and ready for operation. Weigh it on a
commercial scale to ensure that it is not over
the GVWR.
Figure out the weight on the front and rear of
the vehicle separately. It is important that you
distribute the load evenly over the front and rear
axles.
Overloading can cause potential safety hazards
and shorten useful service life. Heavier axles or
suspension components do not necessarily
increase the vehicle's GVWR.
WARNING!
Because the front wheels steer the vehicle, it
is important that you do not exceed the
maximum front or rear GAWR. A dangerous
driving condition can result if either rating is
exceeded. You could lose control of the
vehicle and have a collision.

TOWING TIPS
Before setting out on a trip, practice turning,
stopping, and backing up the trailer in an area
located away from heavy traffic.
Automatic Transmission — If Equipped
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
performance and extend transmission life by
reducing excessive shifting and heat buildup.
This action will also provide better engine
braking.
Speed Control — If Equipped
Do not use on hilly terrain or with heavy
loads.
When using the Speed Control, if you experi -
ence speed drops greater than 10 mph
(16 km/h), disengage until you can get back
to cruising speed.
Use Speed Control in flat terrain and with
light loads to maximize fuel efficiency.
AutoStick
When using the AutoStick shift control, select
the highest gear that allows for adequate
performance and avoids frequent down -
shifts. For example, choose “5” if the desired
speed can be maintained. Choose “4” or “3”
if needed to maintain the desired speed.
To prevent excess heat generation, avoid
continuous driving at high RPM. Reduce
vehicle speed as necessary to avoid
extended driving at high RPM. Return to a
higher gear or vehicle speed when grade and
road conditions allow.
Cooling System
To reduce potential for engine and transmission
overheating, take the following actions:
City Driving
In city traffic — while stopped, place the trans -
mission in NEUTRAL, but do not increase
engine idle speed.
Highway Driving
Reduce speed.
Temporarily turn off air conditioning.
