ENGINE BREAK-IN RECOMMENDATIONS
3.6L Engine Break-In
For vehicles equipped with the 3.6L, use the following engine break-in recommendations:
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, refer to “Maintenance
Procedures” in “Maintaining Your Vehicle”.
CAUTION!
Never use Non-Detergent Oil or Straight Mineral Oil in the engine or damage may
result.
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 indicator often during the break in period. Add oil as required.
5.7L Engine Break-In
For vehicles equipped with the 5.7L, use the following engine break-in recommendations:
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.

interpreted as an indication of difficulty. Please check your oil level with the engine
oil indicator often during the break in period. Add oil as required.
6.4L Engine Break-In
For vehicles equipped with the 6.4L use the following engine break-in recommendations:
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 160 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 acceleration.
• 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 (160 to 483 km):
• Depress the accelerator pedal slowly and not more than halfway to avoid rapid acceleration in lower gears (1st to 3rd 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 (paddles or gear shift) at higher rpms 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 1500 miles (2414 km):
• Do not participate in track events, sport driving schools, or similar activities duringthe first 1500 miles (2414 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.
HEADLIGHT SWITCH
The headlight switch is located on the left side of the instrument panel, next to the
steering wheel. The headlight switch controls the operation of the headlights, parking
lights, instrument panel lights, cargo lights and fog lights (if equipped).
To turn on the headlights, rotate the
headlight switch clockwise. When the
headlight switch is on, the parking lights,
taillights, license plate light and instru-
ment panel lights are also turned on. To
turn off the headlights, rotate the head-
light switch back to the O (Off) position.
NOTE:
• Your vehicle is equipped with plastic headlight and fog light (if equipped)
lenses that are lighter and less suscep-
tible to stone breakage than glass
lights. Plastic is not as scratch resis-
tant as glass and therefore different
lens cleaning procedures must be fol-
lowed.
• To minimize the possibility of scratch- ing the lenses and reducing light out-
put, avoid wiping with a dry cloth. To
remove road dirt, wash with a mild
soap solution followed by rinsing.
CAUTION!
Do not use abrasive cleaning components, solvents, steel wool or other abrasive
materials to clean the lenses.

Automatic Headlights — If Equipped
This system automatically turns the headlights on or off according to ambient light
levels. To turn the system on, rotate the headlight switch to the A (AUTO) position.
When the system is on, the Headlight Delay feature is also on. This means the
headlights will stay on for up to 90 seconds after you turn the ignition switch to the
OFF position. To turn the automatic headlights off, turn the headlight switch out of
the AUTO position.
NOTE:
The engine must be running before the headlights will turn on in the Automatic
Mode.
Automatic High Beam — If Equipped
The Automatic High Beam Headlamp Control system provides increased forward
lighting at night by automating high beam control through the use of a digital camera
mounted on the inside rearview mirror. This camera detects vehicle specific light and
automatically switches from high beams to low beams until the approaching vehicle
is out of view.
NOTE:
• The Automatic High Beam Headlamp Control can be turned on or off using theUconnect System. Refer to “Uconnect Settings” in “Understanding Your Instru-
ment Panel” in the Owner’s Manual on the DVD for further information.
• Broken, muddy, or obstructed headlights and taillights of vehicles in the field of view will cause headlights to remain on longer (closer to the vehicle). Also, dirt,
film, and other obstructions on the windshield or camera lens will cause the
system to function improperly.
• To opt out of the Advanced Auto High-Beam Sensitivity Control (default) and enter Reduced High-Beam Sensitivity Control (not recommended), toggle highbeam
lever 6 full on/off cycles within 10 seconds of ignition ON. System will return to
default setting upon ignition off.
If the windshield or Automatic High Beam Headlamp Control mirror is replaced, the
mirror must be re-aimed to ensure proper performance. See your local authorized
dealer.
Interior Lights
Courtesy and dome lights are turned on when the front doors are opened or when the
dimmer control (rotating wheel on the right side of the headlight switch) is rotated to
its farthest upward position. If your vehicle is equipped with Remote Keyless Entry
(RKE) and the UNLOCK button is pressed on the RKE transmitter the courtesy and
dome lights will turn on. When a door is open and the interior lights are on, rotating
the dimmer control all the way down, to the OFF detent, will cause all the interior
lights to go out. This is also known as the “Party” mode because it allows the doors
to stay open for extended periods of time without discharging the vehicle’s battery.

The brightness of the instrument panel lighting can be regulated by rotating the
dimmer control up (brighter) or down (dimmer). When the headlights are on you can
supplement the brightness of the odometer, trip odometer, radio and overhead
console by rotating the control to its farthest position up until you hear a click. This
feature is termed the “Parade” mode and is useful when headlights are required
during the day.
TURN SIGNAL/WIPER/WASHER/HIGH BEAM LEVER
The multifunction lever is located on the left side of the steering column.
Turn Signals
Move the multifunction lever up or down and the arrows on each side of the
instrument cluster flash to show proper operation of the front and rear turn signal
lights.
NOTE:
If either light remains on and does not flash, or there is a very fast flash rate, check
for a defective outside light bulb. If an indicator fails to light when the lever is moved,
it would suggest that the indicator bulb is defective.
Lane Change Assist
Tap the lever up or down once, without moving beyond the detent, and the turn signal
(right or left) will flash three times then automatically turn off.
High/Low Beam Switch
Push the multifunction lever toward the instrument panel to switch the headlights to
high beams. Pulling the multifunction back toward the steering wheel will turn the
low beams back on, or shut the high beams off.

Windshield Wipers And Washers
The windshield wiper/washer controls are located on the multifunction lever on the
left side of the steering column. The front wipers are operated by rotating a switch,
located on the end of the lever. For information on the rear wiper/washer, refer to
“Rear Window Wiper/Washer” in this section.
Windshield Wiper Operation
Rotate the end of the lever to one of the first four detent positions for intermittent
settings, the fifth detent for low wiper operation and the sixth detent for high wiper
operation.
CAUTION!
Always remove any buildup of snow that prevents the windshield wiper blades
from returning to the “park” position. If the windshield wiper switch is turned off,
and the blades cannot return to the “park” position, damage to the wiper motor
may occur.
Intermittent Wiper System
Use one of the four intermittent wiper settings when weather conditions make a
single wiping cycle, with a variable delay between cycles, desirable. At driving speeds
above 10 mph (16 km/h), the delay can be regulated from a maximum of approxi-
mately 18 seconds between cycles (first detent), to a cycle every one second (fourth
detent).
NOTE:
If the vehicle is moving less than 10 mph (16 km/h), delay times will be doubled.
Windshield Washer Operation
To use the washer, push on the end of the lever (toward the steering wheel) and hold
while spray is desired. If the lever is pushed while in the intermittent setting, the
wipers will turn on and operate for several wipe cycles after the end of the lever is
released, and then resume the intermittent interval previously selected.
If the end of the lever is pushed while the wipers are in the off position, the wipers
will operate for several wipe cycles, then turn off.
WARNING!
Sudden loss of visibility through the windshield could lead to a collision. You
might not see other vehicles or other obstacles. To avoid sudden icing of the
windshield during freezing weather, warm the windshield with the defroster before
and during windshield washer use.
OPERATING YOUR VEHICLE
47

Mist
Use the Mist feature when weather conditions make occasional usage of the wipers
necessary. Rotate the end of the lever downward to the Mist position and release for
a single wiping cycle.
NOTE:
The mist feature does not activate the washer pump; therefore, no washer fluid will
be sprayed on the windshield. The wash function must be used in order to spray the
windshield with washer fluid.
Rain Sensing Wipers — If Equipped
This feature senses moisture on the windshield and automatically activates the
wipers for the driver. The feature is especially useful for road splash or overspray from
the windshield washers of the vehicle ahead. Rotate the end of the multifunction
lever to one of four settings to activate this feature.
The sensitivity of the system can be adjusted with the multifunction lever. Wiper
delay position one is the least sensitive, and wiper delay position four is the most
sensitive. Setting three should be used for normal rain conditions. Settings one and
two can be used if the driver desires less wiper sensitivity. Setting four can be used
if the driver desires more sensitivity. Place the wiper switch in the OFF position when
not using the system.
NOTE:
• The Rain Sensing feature will not operate when the wiper switch is in the low orhigh-speed position.
• The Rain Sensing feature may not function properly when ice, or dried salt water is present on the windshield.
• Use of Rain-X or products containing wax or silicone may reduce Rain Sensing performance.
• The Rain Sensing feature can be turned on and off using the Uconnect System, refer to “Uconnect Settings” in “Understanding Your Instrument Panel” in the
Owners Manual on the DVD for further information.
