NOTE:The engine and transmission 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 filter housing aids in
preventing fuel gelling. It is controlled by a built-in
thermostat.
• A Diesel Pre-Heat system both improves engine start-
ing and reduces the amount of white smoke generated
by a warming engine.

Cooling System Tips — Automated Manual
Transmission
To reduce potential for engine and transmission over-
heating in high ambient temperature conditions, take the
following actions:
•City Driving
— When stopped, shift the transmis-
sion into NEUTRAL and increase engine idle
speed.
• Highway Driving— Reduce your speed.
•Up Steep Hills— Select a lower transmission gear.
•Air Conditioning— Turn it off temporarily. Do Not Operate The Engine With Low Oil
Pressure
If the low oil pressure warning light turns on while
driving, stop the vehicle and shut down the engine as
soon as possible. A chime will sound when the light turns
on.
NOTE:
Do not operate the vehicle until the cause is
corrected. This light does not show how much oil is in the
engine. The engine oil level must be checked under the
hood.
CAUTION!
If oil pressure falls to less than normal readings, shut
the engine off immediately. Failure to do so could
result in immediate and severe engine damage.

Do Not Operate The Engine With Failed Parts
All engine failures give some warning before the parts
fail. Be on the alert for changes in performance, sounds,
and visual evidence that the engine requires service.
Some important clues are:
•engine misfiring or vibrating severely
• sudden loss of power
• unusual engine noises
• fuel, oil or coolant leaks
• sudden change, outside the normal operating range, in
the engine operating temperature
• excessive smoke
• oil pressure drop
ENGINE BLOCK/TRANSMISSION HEATER — IF
EQUIPPED
To ensure reliable starting/operating at these tempera-
tures, use of an externally powered electric engine block/
transmission heater (available from your authorized
dealer) is recommended.
The engine block heater warms engine coolant and
permits quicker starts in cold weather. The transmission
heaters warm gearbox oil and hydraulic actuation system
oil to operate in cold weather. Connect the heater cord to
a ground-fault interrupter protected 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
5
STARTING AND OPERATING 45

and should be plugged in two hours prior to start. Its use
is required for cold starts with temperatures under -17°F
(-27°C).
In the case of LOW temperature after Starting, the
Automated Manual Transmission may not be able to
engage first gear. In this case a messageShift not
allowed appears. In this situation use the engine block
heater.
WARNING!
Remember to disconnect the cord before driving.
Damage to the 110–115 Volt electrical cord could
cause electrocution.
NOTE: The block heater will require 110 Volts AC and
6.5 Amps to activate the heater element.
AUTOMATED MANUAL TRANSMISSION
WARNING!
You or others could be injured if you leave the
vehicle unattended without fully applying the park-
ing brake. The parking brake should always be
applied when the driver is not in the vehicle.
The automated manual transmission is a conventional
six-speed manual transmission with an electronically-
controlled hydraulic system that controls the clutch and
gear shifting. In forward gears, this transmission offers
two modes of operation:
• MANUAL (M) Mode — where the driver controls the
transmission shifting.
• Automatic Mode (the DRIVE [D] position)
— where
the electronic system controls the gear shifts.
46 STARTING AND OPERATING
Page 53 of 130

•At low speeds you may hear mechanical noises similar
to a manual transmission as the transmission changes
gears. These noises are normal and will not damage
the transmission.
• Very aggressive driving may result in some clutch
odor. A warning message will display in the EVIC if
cool down actions are needed.
• Before and after the engine is started, you may hear a
hydraulic pump for a short period of time. This noise
is normal and will not damage the transmission.
• During extremely cold temperatures, the transmission
will not operate if the oil temperature is -22°F (-30°C)
or below. When transmission actuation oil temperature
is lower than -22°F (-30°C), engine start will not be
allowed by PCM. For this reason the block heater is
recommended below -17°F (-27°C). Normal operation
will resume once the transmission temperature has
risen to a suitable level.Manual (M) (Manual Mode)
In the MANUAL (M) position the driver is responsible
for choosing the best gear ratio to engage, depending on
driving conditions.
NOTE: Do not press the brake and accelerator pedals at
the same time. Use only one foot to operate the brake and
accelerator.
To operate in MANUAL (M) mode:
• Press and hold the brake pedal.
• Move the shift lever to the MANUAL (M) position.
The current gear will be displayed in the EVIC.
• To drive, release the brake pedal and press the accel-
erator pedal.
• Tap the shift lever towards the (+) to engage a higher
gear.
5
STARTING AND OPERATING 51
Page 54 of 130

•Tap the shift lever towards the (–) position to engage a
lower gear.
• The accelerator pedal need not be released during gear
changes in MANUAL mode.
• You can shift between DRIVE (D) and MANUAL (M)
positions at any speed, without taking your foot off the
accelerator pedal.
• The system will shift down through the gears auto-
matically (to prevent engine lugging) during closed-
throttle decelerations.
• The transmission will automatically downshift to first
gear when coming to a stop. After a stop, the driver
should manually upshift (+) the transmission as the
vehicle is accelerated.
• You can start out, from a stop, in first or second gear.
Tap (+) (at a stop) to select second gear. Starting out in
second gear may be helpful in snowy or icy conditions. •
The system will ignore shift commands that would
cause engine lugging or overspeed. An audible beep
will sound and a Shift not allowed message will
display in the EVIC if an inappropriate gear is re-
quested.
NOTE: Avoid keeping your hand on the lever when you
are not requesting a gear shift.
Warning Buzzers
To provide awareness, a warning buzzer sounds when
the vehicle is parked with the transmission in NEUTRAL
(N) (the warning sounds when the ignition is turned to
the off position).
The warning buzzer also sounds to indicate an inconsis-
tent shift lever position (i.e. when the shift lever position
does not match the actual transmission gear position).
52 STARTING AND OPERATING
Page 55 of 130

This can occur, for example, if the driver moves the shift
lever to request a transmission gear that is not allowed
under the current operating conditions.
With the vehicle at a standstill, engine running and the
shift lever in DRIVE (D), REVERSE (R), or MANUAL
(M), the buzzer sounds and the transmission automati-
cally shifts to NEUTRAL (N) when:
•The accelerator and/or brake pedals are not operated
for at least three minutes.
• The brake pedal is pressed for longer than 10 minutes.
• The driver ’s door is opened and the accelerator and
brake are not operated for at least 1.5 seconds.
• The driver selected gear does not match the engaged
transmission gear.
• A fault has been detected in the transmission. A Blinking Warning:
•
The driver selected gear does not match the engaged
transmission gear, the gear information in the cluster
and on the bezel will blink.
When To Use TOW/HAUL Mode
When driving in hilly areas, towing a trailer, carrying a
heavy load, etc., and frequent transmission shifting oc-
curs, press the TOW/HAUL switch to activate TOW/
HAUL mode. This will improve performance and reduce
the potential for transmission overheating or failure due
to excessive shifting. When operating in TOW/HAUL
mode, the transmission shift calibration is modified to
accommodate steep grades in the smoothest possible
manner. TOW/HAUL mode is only applicable in the
DRIVE (D) position.

Parking The Vehicle
WARNING!
You or others could be injured if you leave the
vehicle unattended without fully applying the park-
ing brake. The parking brake should always be
applied when the driver is not in the vehicle.
To ensure proper parking performance, it is essential to
engage MANUAL (1st) gear, DRIVE (D) or REVERSE (R)
gear while your foot is on the brake pedal. Once
MANUAL (1st) gear, DRIVE (D) or REVERSE (R) gear is
displayed in the EVIC, turn the engine off and engage the
parking brake. It is essential to wait until the gear
engaged appears in the display before turning the engine
off and releasing the brake pedal. Always remember to
set your parking brake. NOTE:
NEVER leave your vehicle with the gearbox in
NEUTRAL (N) without the parking brake engaged. Al-
ways remember to fully apply your parking brake.
Always remember to set the parking brake when the “Set
Park Brake” message is displayed.
General Warnings
• With the vehicle at a standstill and a gear engaged,
keep the brake pedal pressed until you decide to drive
away. Then release the brake and accelerate gradually.
• When parked for long periods with the engine run-
ning, it is advisable to place the transmission in
NEUTRAL (N) and apply the parking brake.
• To avoid accelerated clutch wear, do not use the
accelerator to keep the vehicle at a standstill (for
