tor, brake, or clutch pedals then re-
install the floor mats.
• It is recommended to only use mild soap
and water to clean your floor mats. After
cleaning, always check your floor mat
has been properly installed and is se-
cured to your vehicle using the floor mat
fasteners by lightly pulling mat.
Periodic Safety Checks You Should Make
Outside The Vehicle
Tires
Examine tires for excessive tread wear and
uneven wear patterns. Check for stones,
nails, glass, or other objects lodged in the
tread or sidewall. Inspect the tread for cuts and cracks. Inspect sidewalls for cuts,
cracks, and bulges. Check the wheel nuts for
tightness. Check the tires (including spare)
for proper cold inflation pressure.
Lights
Have someone observe the operation of brake
lights and exterior lights while you work the
controls. Check turn signal and high beam
indicator lights on the instrument panel.
Door Latches
Check for proper closing, latching, and lock-
ing.
Fluid Leaks
Check area under vehicle after overnight
parking for fuel, engine coolant, oil, or other
fluid leaks. Also, if gasoline fumes are de-
tected or if fuel, power steering fluid (if
equipped), or brake fluid leaks are sus-
pected. The cause should be located and
corrected immediately.
145

The starter is allowed to crank for up to
30-second intervals. Waiting a few minutes
between such intervals will protect the starter
from overheating.
WARNING!
• Before exiting a vehicle, always shift theautomatic transmission into PARK and
apply the parking brake. Always make
sure the keyless ignition node is in the
“OFF” mode, remove the key fob from
the vehicle and lock the vehicle.
• Never leave children alone in a vehicle,
or with access to an unlocked vehicle.
Leaving children in a vehicle unattended
is dangerous for a number of reasons. A
child or others could be seriously or
fatally injured. Children should be
warned not to touch the parking brake,
brake pedal or the gear selector.
• Do not leave the key fob in or near the
vehicle, or in a location accessible to
children, and do not leave the ignition of
a vehicle equipped with Keyless Enter-
N-Go in the ACC or ON/RUN mode. A
WARNING!
child could operate power windows,
other controls, or move the vehicle.
• Do not leave children or animals inside
parked vehicles in hot weather. Interior
heat build-up may cause serious injury
or death.
NOTE:
Engine start up in very low ambient tempera-
ture could result in evident white smoke. This
condition will disappear as the engine warms
up.
CAUTION!
• The engine is allowed to crank as long as 30 seconds. If the engine fails to start
during this period, please wait at least
two minutes for the starter to cool before
repeating start procedure.
• If the “Water in Fuel Indicator Light”
remains on, DO NOT START engine be-
fore you drain the water from the fuel
filters to avoid engine damage. Refer to
“Draining Fuel/Water Separator Filter”
CAUTION!
in “Servicing And Maintenance” for fur-
ther information.
Automatic Transmission
Start the engine with the transmission gear
selector in the PARK position. Apply the
brake before shifting to any driving range.
Extreme Cold Weather
The engine block heater is a resistance heater
installed in the water jacket of the engine. It
requires a 110–115 Volt AC electrical outlet
with a grounded, three-wire extension cord.
Its use is recommended for environments
that routinely fall below -10°F (-23°C). It
should be used when the vehicle has not been
running overnight or longer periods and
should be plugged in two hours prior to start.
Its use is required for cold starts with tem-
peratures under -20°F (-28°C).
151

NOTE:
The engine block heater cord is a factory
installed option. If your vehicle is not
equipped, heater cords are available from
your authorized MOPAR dealer.
• A 12 Volt heater built into the fuel filterhousing aids in preventing fuel gelling. It is
controlled by a built-in thermostat.
• A Diesel Pre-Heat system both improves engine starting and reduces the amount of
white smoke generated by a warming
engine.
Normal Starting Procedure — Keyless
Enter-N-Go
Observe the instrument panel cluster lights
when starting the engine.
NOTE:
Normal starting of either a cold or a warm
engine is obtained without pumping or press-
ing the accelerator pedal
1. Always apply the parking brake.
2. Press and hold the brake pedal while pushing the ENGINE START/STOP button
once. NOTE:
A delay of the start of up to five seconds is
possible under very cold conditions. The

ENGINE BREAK-IN
RECOMMENDATIONS
3.6L & 5.7L Engines
For vehicles equipped with the 3.6L or 5.7L use
the following engine break-in recommenda-
tions: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.
155

Diesel Engines
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 underload.
• 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
towing or no load operation will extend the
time before the engine is at full efficiency.
Reduced fuel economy and power may be
seen at this time. 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 ac-
celeration.
• 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 ac-
celeration 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.
STARTING AND OPERATING
156

CAUTION!
Damage to the transmission may occur if
the following precautions are not ob-
served:
• Shift into or out of PARK or REVERSEonly after the vehicle has come to a
complete stop.
• Do not shift between PARK, REVERSE,
NEUTRAL, or DRIVE when the engine is
above idle speed.
• Before shifting into any gear, make sure
your foot is firmly pressing the brake
pedal.
NOTE:
You must press and hold the brake pedal
while shifting out of PARK.
Ignition Park Interlock
This vehicle is equipped with a Ignition Park
Interlock which requires the transmission to
be in PARK before the ignition can be turned
to the OFF mode. This helps the driver avoid
inadvertently leaving the vehicle without placing the transmission in PARK. This sys-
tem also locks the transmission in PARK
whenever the ignition is in the OFF mode.
Brake/Transmission Shift Interlock
System
This vehicle is equipped with a Brake Trans-
mission Shift Interlock system (BTSI) that
holds the transmission gear selector in PARK
unless the brakes are applied. To shift the
transmission out of PARK, the engine must
be running and the brake pedal must be
pressed. The brake pedal must also be
pressed to shift from NEUTRAL into DRIVE or
REVERSE when the vehicle is stopped or
moving at low speeds.
Fuel Economy (ECO) Mode
The Fuel Economy (ECO) mode can improve
the vehicle's overall fuel economy during nor-
mal driving conditions. Push the “ECO”
switch in the center stack of the instrument
panel to activate or disable ECO mode. An
amber light on the switch indicates when
ECO mode is disabled (for regular models) or
a blue light when enabled (for SRT models).
When the Fuel Economy (ECO) Mode is en-
gaged, the vehicle control systems will
change the following:
• The transmission will upshift sooner and
downshift later.
• The overall driving performance will be more conservative.
• Vehicles with Quadra-Lift air suspension will operate in "Aero" mode over a broader
speed range. Refer to the section on
Quadra-Lift for further information.

WARNING!
You or others could be injured or killed if
you leave the vehicle unattended with the
power transfer unit in the NEUTRAL (N)
position without first fully engaging the
parking brake. The NEUTRAL (N) position
disengages both the front and rear drive-
shafts from the powertrain and will allow
the vehicle to roll, even if the transmission
is in PARK. The parking brake should al-
ways be applied when the driver is not in
the vehicle.
4WD LOW
This range is for low speed four-wheel drive. It
provides an additional gear reduction which
allows for increased torque to be delivered to
both the front and rear wheels while providing
maximum pulling power for loose, slippery
road surfaces only. Do not exceed 25 mph
(40 km/h).
NOTE:
Refer to “Selec-Terrain – If Equipped” for
further information on the various positions
and their intended usages.
Shifting Procedures
4WD HI To 4WD LOW
With the vehicle at speeds of 0 to 3 mph (0 to
5 km/h), the ignition switch in the ON posi-
tion or the engine running, shift the transmis-
sion into “N”, and push the “4WD LOW”
button once on the transfer case switch. The
“4WD LOW” indicator light in the instrument
cluster will begin to flash and remain on solid
when the shift is complete.NOTE:
If shift conditions/interlocks are not met, or a
transfer case motor temperature protection
condition exists, a “For 4x4 Low Slow Below
3 mph (5 km/h) Put Trans in “N” Press
4 Low” message will flash from the instru-
ment cluster display. Refer to “Instrument
Cluster Display” in “Getting To Know Your
Instrument Panel” for further information.
4WD LOW To 4WD HI
With the vehicle at speeds of 0 to 3 mph (0 to
5 km/h), the ignition switch in the ON posi-
tion or the engine running, shift the transmis-
sion into NEUTRAL, and push the “4WD
LOW” button once on the transfer case
switch. The “4WD LOW” indicator light in the
instrument cluster will flash and go out when
the shift is complete.
