The engine oil installed in the engine at the
factory is a high-quality energy conserving
type lubricant. Oil changes should be consis-
tent with anticipated climate conditions un-
der which vehicle operations will occur. The
recommended viscosity and quality grades
are shown under “Fluids And Lubricants” in
"Technical Specifications” in this manual.
NON-DETERGENT OR STRAIGHT MINERAL
OILS MUST NEVER BE USED.
SRT Engines
The following tips will be helpful in obtaining
optimum performance and maximum dura-
bility for your new SRT 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 accel-
eration.
• 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 accel-
eration 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 during
the first 1500 mi (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 inter-
val. Running the engine with an oil level
below the add mark can cause severe engine
damage.

Adding Diesel Exhaust Fluid
The DEF gauge (located on the instrument
cluster display) will display the level of DEF
remaining in the tank. Refer to “Instrument
Cluster Display” in “Getting To Know Your
Instrument Panel” for further information.
NOTE:
Driving conditions (altitude, vehicle speed,
load, etc.) will effect the amount of DEF that
is used in your vehicle.
DEF Fill Procedure
NOTE:
Refer to “Fluids And Lubricants” in the
“Technical Specifications” section for the
correct fluid type.
1. Remove cap from DEF fill inlet (located in
fuel door).
2. Insert DEF fill adapter/nozzle into DEF fill
inlet.NOTE:
• The DEF gauge may take up to five
seconds to update after adding a gallon
or more of Diesel Exhaust Fluid (DEF)
to the DEF tank. If you have a fault
related to the DEF system, the gauge
may not update to the new level. See an
authorized dealer for service.
• The DEF gauge may also not immedi-
ately update after a refill if the tempera-
ture of the DEF fluid is below 12F
(-11C). The DEF line heater will possi-
bly warm up the DEF fluid and allow the
gauge to update after a period of run
time. Under very cold conditions, it is
possible that the gauge may not reflect
the new fill level for several drives.

Raising the vehicle higher than necessary
can make the vehicle less stable. It could
slip off the jack and hurt someone near it.
Raise the vehicle only enough to remove
the tire.
7. Remove the lug nuts and wheel.
8. Position the spare wheel/tire on the ve-
hicle and install the lug nuts with the
cone-shaped end toward the wheel.
Lightly tighten the nuts.
CAUTION!
Be sure to mount the spare tire with the
valve stem facing outward. The vehicle
could be damaged if the inflatable spare
tire is mounted incorrectly.
WARNING!
To avoid the risk of forcing the vehicle off
the jack, do not tighten the wheel nuts
fully until the vehicle has been lowered.
Failure to follow this warning may result in
serious injury.
9. Lower the vehicle by turning the jack
screw counterclockwise, and remove the
jack and wheel blocks.10. Finish tightening the lug nuts. Push
down on the wrench while at the end of
the handle for increased leverage.
Tighten the lug nuts in a star pattern
until each nut has been tightened twice.
For correct lug nut torque, refer to
“Torque Specifications” in “Technical
Specifications”. If in doubt about the
correct tightness, have them checked
with a torque wrench by your authorized
dealer or at a service station.
11. Lower the jack to the fully closed posi-
tion and return it and the tools to the
proper positions in the foam tray.

12. Remove the small center cap and se-
curely store the road wheel in the cargo
area.
13. Have the aluminum road wheel and tire
repaired as soon as possible, properly
secure the spare tire with the special
wing nut torqued to 3.7 ft-lbs (5 N·m),
reinstall the jack and tool kit foam tray,
and latch the rear load floor cover.NOTE:
Do not drive with the spare tire installed for
more than 50 miles (80 km) at a max speed
of 50 mph (80 km/h).
WARNING!
A loose tire or jack thrown forward in a
collision or hard stop could endanger the
occupants of the vehicle. Always stow the
jack parts and the spare tire in the places
provided. Have the deflated (flat) tire re-
paired or replaced immediately.
Road Tire Installation
1. Mount the road tire on the axle.
2. Install the remaining lug nuts with the
cone shaped end of the nut toward the
wheel. Lightly tighten the lug nuts.
WARNING!

fully until the vehicle has been lowered.
Failure to follow this warning may result in
serious injury.
3. Lower the vehicle to the ground by turning
the jack handle counterclockwise.
4. Refer to “Torque Specifications” in
“Technical Specifications” for proper lug
nut torque.
5. After 25 miles (40 km), check the lug nut
torque with a torque wrench to ensure that
all lug nuts are properly seated against the

are recommended. Using gasolines that have
these additives may help improve fuel
economy, reduce emissions, and maintain
vehicle performance.
Poor quality gasoline can cause problems
such as hard starting, stalling and stumble. If
you experience these problems, try another
brand of gasoline before considering service
for the vehicle.
5.7L Engine
Theses engines are designed to meet all
emissions regulations and provide satisfac-
tory fuel economy and performance when
using high-quality unleaded gasoline having
an Research Octane Number (RON) of 91 to
95. The manufacturer recommends the use
of a 95 Research Octane Number for opti-
mum performance.
Light spark knock at low engine speeds is not
harmful to your engine. However, continued
heavy spark knock at high speeds can cause
damage, and immediate service is required.
Poor quality gasoline can cause problems
such as hard starting, stalling, and hesita-tions. If you experience these symptoms, try
another brand of gasoline before considering
service for the vehicle.
Besides using unleaded gasoline with the
proper octane rating, gasolines that contain
detergents, corrosion and stability additives
are recommended. Using gasolines that have
these additives may help improve fuel
economy, reduce emissions, and maintain
vehicle performance.
Poor quality gasoline can cause problems
such as hard starting, stalling and stumble. If
you experience these problems, try another
brand of gasoline before considering service
for the vehicle.
6.2L/6.4L Engine
Your vehicle is designed to meet all emissions
regulations and provide excellent fuel
economy and performance when using high-
quality unleaded gasoline having an Re-
search Octane Number (RON) of 98 or
higher. The manufacturer recommends the
use of 98 Research Octane Number (RON) or
higher for optimum performance.Light spark knock at low engine speeds is not
harmful to your engine. However, continued
heavy spark knock at high speeds can cause
damage and immediate service is required.
Poor quality gasoline can cause problems
such as hard starting, stalling, and hesita-
tions. If you experience these symptoms, try
another brand of gasoline before considering
service for the vehicle.
Methanol
(Methyl) is used in a variety of concentrations
when blended with unleaded gasoline. You
may find fuels containing 3% or more metha-
nol along with other alcohols called cosol-
vents. Problems that result from using
methanol/gasoline are not the responsibility
of the manufacturer. While MTBE is an oxy-
genate made from Methanol, it does not have
the negative effects of Methanol.
WARNING!
Do not use gasolines containing Methanol.
Use of these blends may result in starting
and drivability problems and may damage
critical fuel system components.
