STARTING AND OPERATING163
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, 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 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 (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.
CAUTION!
Never use Non-Detergent Oil or Straight
Mineral Oil in the engine or damage may result.
5
20_LD_OM_EN_USC_t.book Page 163

164STARTING AND OPERATING
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.
PARKING BRAKE
Before leaving the vehicle, make sure that the
parking brake is fully applied and place the gear
selector in the PARK position. The foot operated parking brake is located
below the lower left corner of the instrument
panel. To apply the park brake, firmly push the
parking brake pedal fully. To release the parking
brake, press the parking brake pedal a second
time and let your foot up as you feel the brake
disengage.
Parking Brake
When the parking brake is applied with the
ignition switch in the ON/RUN position, the
Brake Warning Light in the instrument cluster
will illuminate. NOTE:
When the parking brake is applied and the
transmission 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.
This light only shows that the parking brake is
applied. It does not show the degree of brake
application.
When parking on a hill, it is important to turn the
front wheels toward the curb on a downhill
grade and away from the curb on an uphill
grade. Apply the parking brake before placing
the gear selector in PARK, otherwise the load on
the transmission locking mechanism may make
it difficult to move the gear selector out of PARK.
The parking brake should always be applied
whenever the driver is not in the vehicle.

SERVICING AND MAINTENANCE
SCHEDULED SERVICING
3.6L AND 5.7L ENGINES
These vehicles are equipped with an automatic
oil change indicator system. The oil change
indicator system will remind you that it is time to
take your vehicle in for scheduled maintenance.
Based on engine operation conditions, the oil
change indicator message will illuminate. This
means that service is required for your vehicle.
Operating conditions such as frequent
short-trips, trailer tow, and extremely hot or cold
ambient temperatures will influence when the
“Change Oil” or “Oil Change Required” message
is displayed. Severe Operating Conditions can
cause the change oil message to illuminate as
early as 3,500 miles (5,600 km) since last
reset. Have your vehicle serviced as soon as
possible, within the next 500 miles (805 km).
The “Oil Change Required” message will be
displayed in the instrument cluster and a single
chime will sound, indicating that an oil change
is necessary.An authorized dealer will reset the oil change
indicator message after completing the
scheduled oil change. If a scheduled oil change
is performed by someone other than an
authorized dealer, the message can be reset by
referring to “Instrument Cluster Display” in
“Getting To Know Your Instrument Panel” for
further information.
NOTE:
Under no circumstances should oil change
intervals exceed 10,000 miles (16,000 km),
12 months or 350 hours of engine run time,
whichever comes first. The 350 hours of engine
run or idle time is generally only a concern for
fleet customers.
Severe Duty All Models
Change Engine Oil at 4,000 miles (6,500 km) or
350 hours of engine run time if the vehicle is
operated in a dusty and off-road environment,
or is operated predominantly at idle or only very
low engine RPM. This type of vehicle use is
considered Severe Duty.
Once A Month Or Before A Long Trip:
Check engine oil level.
Check windshield washer fluid level.
Check tire pressure and look for unusual
wear or damage. Rotate tires at the first sign
of irregular wear, even if it occurs before your
next scheduled service.
Check the fluid levels of the coolant reservoir,
brake master cylinder, and power steering
(if equipped) and fill as needed.
Check function of all interior and exterior
lights.
Maintenance Plan — 3.6L And 5.7L
Required Maintenance Intervals:
Refer to the maintenance schedules on the
following page for the required maintenance
intervals. More frequent maintenance may be
needed in severe conditions, such as dusty
areas and very short trip driving. In some
extreme conditions, additional maintenance
not specified in the maintenance schedule may
be required.
20_LD_OM_EN_USC_t.book Page 250

SERVICING AND MAINTENANCE255
An authorized dealer will reset the oil change
indicator message after completing the
scheduled oil change. If a scheduled oil change
is performed by someone other than an
authorized dealer, the message can be reset by
