“ON/RUN”), • Push the ENGINE START/STOP button a
third time to return the ignition to the OFF
mode (instrument cluster will display
“OFF”).
Cold Weather Operation (Below –22°F Or
−30°C)
To ensure reliable starting at these tempera-
tures, use of an externally powered electric
engine block heater (available from your Au-
thorized Dealer) is recommended.
After Starting
The idle speed is controlled automatically,
and it will decrease as the engine warms up.
If Engine Fails To Start
WARNING!
• Never pour fuel or other flammable liq-uid into the throttle body air inlet open-
ing in an attempt to start the vehicle.
This could result in flash fire causing
serious personal injury.
• Do not attempt to push or tow your
vehicle to get it started. Vehicles
WARNING!
equipped with an automatic transmis-
sion cannot be started this way. Un-
burned fuel could enter the catalytic
converter and once the engine has
started, ignite and damage the converter
and vehicle.
• If the vehicle has a discharged battery,
booster cables may be used to obtain a
start from a booster battery or the battery
in another vehicle. This type of start can
be dangerous if done improperly. Refer
to “Jump-Starting” in “In Case Of Emer-
gency” for further information.
After Starting
The idle speed is controlled automatically,
and it will decrease as the engine warms up.
STARTING PROCEDURES —
DIESEL ENGINES
Before starting your vehicle, adjust your seat,
both inside and outside mirrors, and fasten
your seat belts.
STARTING AND OPERATING
150

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
"Wait to Start" telltale will be illuminated
during the pre-heat process, When the
engine Wait To Start light goes off the
engine will automatically crank.
CAUTION!
If the “Water in Fuel Indicator Light” re-
mains on, DO NOT START the engine be-
fore you drain the water from the fuel
filters to avoid engine damage. Refer to
“Draining Fuel/Water Separator Filter” in
“Servicing And Maintenance” for further
information.

The engine is equipped with a glow plug
preheating system. If the instructions in this
manual are followed, the engine should start
in all conditions and no type of starting fluid
should be used.
WARNING!
• Do not leave children or animals inside
parked vehicles in hot weather. Interior
heat build up may cause serious injury
or death.
• When leaving the vehicle, 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.
Allowing children to be in a vehicle un-
attended is dangerous for a number of
reasons. A child or others could be seri-
ously or fatally injured. Children should
be warned not to touch the parking
brake, brake pedal or the gear selector.
STARTING AND OPERATING
152

WARNING!
• Do not leave the key fob in or near thevehicle, 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
child could operate power windows,
other controls, or move the vehicle.
STOP/START SYSTEM — IF
EQUIPPED
The Stop/Start function is developed to re-
duce fuel consumption. The system will stop
the engine automatically during a vehicle
stop if the required conditions are met. Re-
leasing the brake pedal or pressing the accel-
erator pedal will automatically re-start the
engine.
Automatic Mode
The Stop/Start feature is
enabled after every nor-
mal customer engine
start. At that time, the
system will go into STOP/
START READY and if all
other conditions are met,
can go into a STOP/START AUTOSTOP AC-
TIVE “Autostop” mode.
To Activate The Autostop Mode, The Following
Must Occur:
• The system must be in STOP/START READY state. A STOP/START READY mes-
sage will be displayed in the instrument
cluster display within the Stop/Start sec-
tion. Refer to “Instrument Cluster Dis-
play” in “Getting To Know Your Instrument
Panel” in your Owners Manual at
www.jeep.com/en/owners/manuals/ .
• The vehicle must be completely stopped.
• The shifter must be in a forward gear and the brake pedal depressed. The engine will shut down, the tachometer
will move to the zero position and the Stop/
Start telltale will illuminate indicating you
are in Autostop. Customer settings will be
maintained upon return to an engine running
condition.
Refer to the “Stop/Start System” in the
“Starting And Operating” section located in
your Owners Manual at
www.jeep.com/en/owners/manuals/ .
Possible Reasons The Engine Does Not
Autostop
Prior to engine shut down, the system will
check many safety and comfort conditions to
see if they are fulfilled. Detailed information
about the operation of the Stop/Start system
may be viewed in the instrument cluster dis-
play Stop/Start Screen. In the following situ-
ations, the engine will not stop:
• Driver’s seat belt is not buckled.
• Driver’s door is not closed.
• Battery temperature is too warm or cold.
• Battery charge is low.
• The vehicle is on a steep grade.
153

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

300 to 500 miles (483 to 805 km):
• Exercise the full engine rpm range, shift-ing 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 interval.
Running the engine with an oil level below
the add mark can cause severe engine dam-
age.AUTOMATIC
TRANSMISSION
WARNING!
• It is dangerous to shift out of PARK or NEUTRAL if the engine speed is higher
than idle speed. If your foot is not firmly
pressing the brake pedal, the vehicle
could accelerate quickly forward or in
reverse. You could lose control of the
vehicle and hit someone or something.
Only shift into gear when the engine is
idling normally and your foot is firmly
pressing the brake pedal.
• Unintended movement of a vehicle
could injure those in or near the vehicle.
As with all vehicles, you should never
exit a vehicle while the engine is run-
ning. Before exiting a vehicle, always
apply the parking brake, shift the trans-
mission into PARK, and turn the ignition
OFF. When the ignition is in the OFF
mode, the transmission is locked in
PARK, securing the vehicle against un-
wanted movement.
WARNING!
• When leaving the vehicle, always makesure the ignition 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.
Allowing children to be in a vehicle un-
attended is dangerous for a number of
reasons. A child or others could be seri-
ously or fatally injured. Children should
be warned not to touch the parking
brake, brake pedal or the transmission
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
in the ACC or ON/RUN mode. A child
could operate power windows, other con-
trols, or move the vehicle.
157

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.
