ENGINE BREAK-IN
RECOMMENDATIONS
3.6L & 5.7L Engines
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 contrib-
utes to a good break-in. However, wide-open
throttle acceleration in low gear can be det-
rimental 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 "Techni-
cal Specifications”.
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 nor-
mal 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.
Diesel Engine
The diesel engine does not require a break-in
period due to its construction. Normal opera-
tion is allowed, providing the following rec-
ommendations are followed:
• Warm up the engine before placing it under
load.
• Do not operate the engine at idle for pro-
longed periods.
• Use the appropriate transmission gear to
prevent engine lugging.
• Observe vehicle oil pressure and tempera-
ture indicators.
• Check the coolant and oil levels frequently.
• Vary throttle position at highway speeds
when carrying or towing significant weight.
NOTE:
Light duty operation such as light trailer tow-
ing or no load operation will extend the time
before the engine is at full efficiency. Re-
duced fuel economy and power may be seen
at this time.
143

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.

Guidelines For Track Use
NOTE:
Because of the extreme conditions encoun-
tered during track use, any damage or wear
associated with track use may not be covered
by warranty.
• If your SRT vehicle is equipped with Drive
Modes they will alter the vehicle’s perfor-
mance in various driving situations. It is
recommended that your vehicle operates in
SPORT or TRACK modes during the track
event.
• Prior to each track event/day, verify all
fluids are at the correct levels. Refer to
“Fluid Capacities” in “Technical Specifica-
tions” for further information.
• Prior to each track event, verify the front
and rear brake pads have more than ½ pad
thickness remaining. If the brake pads re-
quire changing, please burnish prior to
track outing at full pace.
NOTE:
Use of DOT 4 brake fluid is suggested for
extended track usage due to increased ther-
mal capacity.• At the conclusion of each track event, it is
recommended that a brake bleed proce-
dure is performed to maintain the pedal
feel and stopping capability of your Brembo
High Performance brake system.
• It is recommended that each track outing
should end with a minimum of one cool
down lap using minimal braking.
• If equipped with a removable lower front
fascia grille, it is recommended to remove it
for track use during warm/hot weather to
improve cooling airflow to critical pow-
ertrain and cooling system components.
• All SRT vehicles are track tested for
24 hours of endurance, however, it is rec-
ommended that suspension system, brake
system, prop shaft, and ½ shaft boots
should be checked for wear or damage after
every track event.
• Track usage results in increased operating
temperatures of the engine, transmission,
driveline and brake system. This may affect
noise vibrations and harshness (NVH)
countermeasures designed into your ve-
hicle. New components may need to be
installed to return the system to the original
NVH performance.• Tire pressure:
– 40 psi (276 kpa) hot, recommend
32 psi (221 kpa) front, 30 psi
(207 kpa) rear cold
NOTE:
It is recommended that you target 40 psi
(276 kpa) Hot Tire Pressure at the conclusion
of each track session. Starting at 32 psi
(221 kpa) Front & 30 psi (207 kpa) Rear
Cold and adjusting based on ambient & track
conditions is recommended. Tire pressure
can be monitored via the instrument cluster
display and can assist with adjustments.
Track burnishing your brakes:
To avoid “green lining fade” during track use,
the brake pads and rotors must have a ther-
mal burnish for factory installed components
or when new brake friction components are
installed:
1. Use one track session to burnish brakes
by driving at 75% speed. Brake at ap-
proximately 0.60-0.80g maximum with-
out ABS intervention.

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.

Leather Parts
Your leather upholstery can be best preserved
by regular cleaning with a damp soft cloth.
Small particles of dirt can act as an abrasive
and damage the leather upholstery and
should be removed promptly with a damp
cloth. Care should be taken to avoid soaking
your leather upholstery with any liquid.
Please do not use polishes, oils, cleaning
fluids, solvents, detergents, or ammonia-
based cleaners to clean your leather uphol-
stery. Application of a leather conditioner is
not required to maintain the original condi-
tion.NOTE:
If equipped with light colored leather, it
tends to show any foreign material, dirt, and
fabric dye transfer more so than darker col-
ors. The leather is designed for easy cleaning.
CAUTION!
Do not use Alcohol and Alcohol-based
and/or Ketone based cleaning products to
clean leather seats, as damage to the seat
may result.
Glass Surfaces
All glass surfaces should be cleaned on a
regular basis with any commercial
household-type glass cleaner. Never use anabrasive type cleaner. Use caution when
cleaning the inside rear window equipped
with electric defrosters or windows equipped
with radio antennas. Do not use scrapers or
other sharp instruments that may scratch the
elements.
When cleaning the rear view mirror, spray
cleaner on the towel or cloth that you are
using. Do not spray cleaner directly on the
mirror.
