cluster.
NOTE:
In some cases the ParkSense graphic will be
displayed in the instrument cluster. In these
cases, the gear selector must be returned to “P”
to select desired gear.
If the driver shifts into PARK while moving, the
vehicle may AutoPark.
AutoPark will engage ONLY when vehicle speed
is 1.2 mph (1.9 km/h) or less. The message “
Vehicle Speed is Too High to
Shift to P ” will be displayed in the instrument
cluster if vehicle speed is above 1.2 mph
(1.9 km/h).
ALWAYS DO A VISUAL CHECK
that your vehicle
is in PARK by looking for the "P" in the
instrument cluster display and on the gear
selector. As an added precaution, always apply
the parking brake when exiting the vehicle.
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.
AutoPark is a supplemental feature. It is not
designed to replace the need to shift your
vehicle into PARK. It is a backup system
and should not be relied upon as the
primary method by which the driver shifts
the vehicle into PARK.
WARNING! (Continued)
WARNING!
If vehicle speed is above 1.2 mph (1.9 km/h),
the transmission will default to NEUTRAL until
the vehicle speed drops below 1.2 mph
(1.9 km/h). A vehicle left in the NEUTRAL
position can roll. As an added precaution,
always apply the parking brake when exiting
the vehicle.

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.

158STARTING AND OPERATING
(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.

Gear Ranges
Do not depress the accelerator pedal when
shifting from PARK or NEUTRAL into another
gear range.
NOTE:
After selecting any gear range, wait a moment
to allow the selected gear to engage before
accelerating. This is especially important when
the engine is cold.
PARK (P)
This range supplements the parking brake by
locking the transmission. The engine can be
started in this range. Never attempt to use
PARK while the vehicle is in motion. Apply the
parking brake when exiting the vehicle in this
range.
When parking on a level surface, you may shift
the transmission into PARK first, and then apply
the parking brake.
When parking on a hill, apply the parking brake
before shifting the transmission to PARK. As an
added precaution, turn the front wheels toward
the curb on a downhill grade and away from the
curb on an uphill grade. When exiting the vehicle, always:Apply the parking brake.
Shift the transmission into PARK.
Turn the ignition OFF.
Remove the key fob from the vehicle.
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.
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 accel -
erate 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 igni -
tion OFF. When the ignition is in the OFF
mode, the transmission is locked in PARK,
securing the vehicle against unwanted
movement.
When exiting the vehicle, always make sure
the ignition is in the OFF mode, remove the
key fob from the vehicle, and lock the
vehicle.

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)

194STARTING AND OPERATING
(Continued)
Perform the maintenance listed in the
“Scheduled Servicing”. Refer to “Scheduled
Servicing” in “Servicing And Maintenance” for
the proper maintenance intervals. When towing
a trailer, never exceed the GAWR or GCWR
ratings.
Towing Requirements — Tires
Do not attempt to tow a trailer while using a
compact spare tire.
Do not drive more than 50 mph (80 km/h) when towing while using a full size spare tire.
Proper tire inflation pressures are essential
to the safe and satisfactory operation of your
vehicle. Refer to “Tires” in “Servicing And
Maintenance” for proper tire inflation
procedures.
Check the trailer tires for proper tire inflation
pressures before trailer usage.
Check for signs of tire wear or visible tire
damage before towing a trailer. Refer to
“Tires” in “Servicing And Maintenance” for
the proper inspection procedure.
When replacing tires, refer to “Tires” in
“Servicing And Maintenance” for the proper
tire replacement procedures. Replacing tires
with a higher load carrying capacity will not
increase the vehicle's GVWR and GAWR
limits.
Towing Requirements — Trailer Brakes
Do not interconnect the hydraulic brake
system or vacuum system of your vehicle
with that of the trailer. This could cause inad -
equate braking and possible personal injury.
An electronically actuated trailer brake
controller is required when towing a trailer
with electronically actuated brakes. When
towing a trailer equipped with a hydraulic
surge actuated brake system, an electronic
brake controller is not required.
Trailer brakes are recommended for trailers
over 1,000 lbs (453 kg) and required for
trailers in excess of 2,000 lbs (907 kg).
Total weight must be distributed between
the tow vehicle and the trailer such that the
following four ratings are not exceeded :
Max loading as defined on the “Tire and
Loading Information” placard.
GTW
GAWR
Tongue weight rating for the trailer
hitch utilized.
CAUTION!
Do not tow a trailer at all during the first
500 miles (805 km) the new vehicle is
driven. The engine, axle or other parts could
be damaged.
WARNING! (Continued)
Then, during the first 500 miles (805 km)
that a trailer is towed, do not drive over
50 mph (80 km/h) and do not make starts
at full throttle. This helps the engine and
other parts of the vehicle wear in at the
heavier loads.

Flowing/Rising Water
Shallow Standing Water
Although your vehicle is capable of driving
through shallow standing water, consider the
following Warnings and Cautions before
doing so.
WARNING!
Do not drive on or across a road or path
where water is flowing and/or rising (as in
storm run-off). Flowing water can wear away
the road or path's surface and cause your
vehicle to sink into deeper water.
Furthermore, flowing and/or rising water can
carry your vehicle away swiftly. Failure to
follow this warning may result in injuries that
are serious or fatal to you, your passengers,
and others around you.
WARNING!
Driving through standing water limits your
vehicle’s traction capabilities. Do not
exceed 5 mph (8 km/h) when driving
through standing water.
Driving through standing water limits your
vehicle’s braking capabilities, which
increases stopping distances. Therefore,
after driving through standing water, drive
slowly and lightly press on the brake pedal
several times to dry the brakes.
Failure to follow these warnings may result
in injuries that are serious or fatal to you,
your passengers, and others around you.
CAUTION!
Always check the depth of the standing
water before driving through it. Never drive
through standing water that is deeper than
the bottom of the tire rims mounted on the
vehicle.
Determine the condition of the road or the
path that is under water and if there are any
obstacles in the way before driving through
the standing water.
Do not exceed 5 mph (8 km/h) when
driving through standing water. This will
minimize wave effects.
Driving through standing water may cause
damage to your vehicle’s drivetrain compo-
nents. Always inspect your vehicle’s fluids
(i.e., engine oil, transmission, axle, etc.) for
signs of contamination (i.e., fluid that is
milky or foamy in appearance) after driving
through standing water. Do not continue to
operate the vehicle if any fluid appears
contaminated, as this may result in further
damage. Such damage is not covered by
the New Vehicle Limited Warranty.
Getting water inside your vehicle’s engine
can cause it to lock up and stall out, and
cause serious internal damage to the
engine. Such damage is not covered by the
New Vehicle Limited Warranty.
CAUTION! (Continued)

208IN CASE OF EMERGENCY
GENERAL INFORMATION
The fuses protect electrical systems against
excessive current.
When a device does not work, you must check
the fuse element inside the blade fuse for a
break/melt.
Also, please be aware that when using power
outlets for extended periods of time with the
engine off may result in vehicle battery
discharge.

Blade Fuses

UNDERHOOD FUSES
The Front Power Distribution Center is located
in the engine compartment. This module
contains fuses and relays. Fuse cavity location
and descriptions are printed on the inside of the
power distribution center cover.
Front Power Distribution Center LocationFront Power Distribution Center

1 — Fuse Element
2 — Blade Fuse with a good/functional fuse
element.
3 — Blade fuse with a bad/not functional fuse
element (blown fuse).
CAUTION!
When installing the power distribution
center cover, it is important to ensure the
cover is properly positioned and fully
latched. Failure to do so may allow water to
get into the power distribution center and
possibly result in an electrical system
failure.
When replacing a blown fuse, it is important
to use only a fuse having the correct
amperage rating. The use of a fuse with a
rating other than indicated may result in a
dangerous electrical system overload. If a
properly rated fuse continues to blow, it
indicates a problem in the circuit that must
be corrected.
