Extreme Cold Weather
Your vehicle may be equipped with three
heating elements; one engine block heater (a
resistance heater installed in the water jacket
of the engine) and two transmission heaters
(one resistance heater installed under the oil
reservoir of the hydraulic actuation system
and one on the differential cover of the trans-
mission). To ensure reliable starting/
operating in extreme cold temperatures, use
of an externally powered electric engine
block/transmission heater (available from
your authorized dealer) is recommended.
They require a 110–115 Volt AC electrical
outlet with a grounded, three-wire extension
cord. Their use is recommended for environ-
ments that routinely fall below -10°F
(-23°C). They should be used when the ve-
hicle has not been running overnight or lon-
ger periods and should be plugged in two
hours prior to start. Their use is required for
cold starts with temperatures under -17°F
(-27°C).NOTE:
The engine is designed to work at an ambient
temperature ranging from -22°F to + 122°F
(-30°C to + 50C°). Rubber, pipes, timing belt
cover and electronic devices are not designed
to work out of this range.
In the case of LOW temperature after Start-
ing, the Automated Manual Transmission
may not be able to engage first gear. In this
case a message "Shift not allowed" appears.
In this situation use the engine block heater.
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 starting and reduces the amount of
white smoke generated by a warming
engine.
NORMAL OPERATION
Observe the following when the diesel engine
is operating.
• All message center lights are off.
• Malfunction Indicator Light (MIL) is off.
• Generic Warning Light is off.
• Engine Oil Pressure telltale is notilluminated.
Stopping The Diesel Engine
Idle the engine a few minutes before routine
shutdown. After full load operation, idle the
engine three to five minutes before shutting it
down. This idle period will allow the lubricat-
ing oil and coolant to carry excess heat away
from the combustion chamber, bearings, in-
ternal components, and turbocharger. This is
especially important for turbocharged diesel
engines.

ENGINE BREAK-IN RECOMMENDATIONS
— GASOLINE ENGINE
A long break-in period is not required for the
engine and drivetrain (transmission and axle)
in your 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. Wide-open throttle
acceleration in low gear can be detrimental
and should be avoided.
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. For
the recommended viscosity and quality
grades, refer to “Fluids And Lubricants” in
“Technical 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 a problem. Please check your oil level with
the engine oil indicator often during the
break in period. Add oil as required.
ENGINE BREAK-IN RECOMMENDATIONS
– 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.
77

• Vary accelerator pedal position at highwayspeeds 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
the “Technical Specifications” chapter in
this manual. NON-DETERGENT OR
STRAIGHT MINERAL OILS MUST NEVER
BE USED.ELECTRIC PARK BRAKE (EPB) —
DIESEL ONLY (IF EQUIPPED)
Your vehicle is equipped with an Electric
Park Brake System (EPB) that offers simple
operation, and some additional features that
make the park brake more convenient and
useful.
The park brake is primarily intended to pre-
vent the vehicle from rolling while parked.
Before leaving the vehicle, make sure that
the park brake is applied.
You can engage the park brake in two ways;
• Manually, by applying the park brake switch.
• Automatically, by the Auto Park Brake fea- ture whenever the vehicle speed is below
1.25 mph (2 km/h) and the ignition switch
is in the STOP/OFF position.
The park brake switch is located on the in-
strument panel to the right of the instrument
cluster. To apply the parking brake manually, pull and
tilt the top of the switch away from the
instrument panel momentarily. You may hear
a mechanical sound while the parking brake
operates; this is normal operating noise.
Once the parking brake is fully engaged, the
BRAKE warning lamp in the instrument clus-
ter and an indicator on the switch will illumi-
nate. The park brake can be applied even
Electric Park Brake SwitchSTARTING AND OPERATING

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 DRIVE (D) (Automatic mode):
• Press and hold the brake pedal.
• Move the gear selector to the DRIVE (D)position.
NOTE:
If the vehicle is moving, DRIVE engagement
will only occur if the vehicle speed is less
than 2 mph (3 km/h). Otherwise, a chime will
sound, the transmission will shift to NEU-
TRAL, and the DRIVE request must then be
repeated by returning the lever to NEUTRAL
and then back into DRIVE once the speed has
been sufficiently reduced.
• To drive, release the brake pedal and press the accelerator pedal.
When in DRIVE (D) the transmission will shift
gears automatically. The Automated Manual
Transmission uses a geartrain and clutch
similar to other manual transmissions. There- fore, you should become familiar with some
of the normal operational characteristics of
the Automated Manual Transmission:
• Engine torque will be interrupted briefly
during the transmission upshifts, making
these shifts more abrupt than with a typical
automatic transmission. This is normal.
• Although transmission shifting is per- formed automatically, the vehicle will not
"creep" when the brake pedal is released,
and may in fact roll down on an incline.
Leaving from a stop, the accelerator pedal
must be pressed to transmit driving torque
to the wheels.
• In Automatic Mode, the Automated Manual Transmission adapts the gear changing
strategy evaluating the road condition such
as slopes in the road.
• During low-speed driving conditions in first gear, vehicle momentum changes may feel
exaggerated in response to changes in ac-
celerator pedal position. This behavior is
normal and is similar to other vehicles
equipped with manual transmissions. • 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 instrument cluster display 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 tem-
perature is -22°F (-30°C) or below. Normal
operation will resume once the transmission
temperature has risen to a suitable level.
When transmission actuation oil temperature
is lower than -22°F (-30°C), engine start will
not be allowed. For this reason the block
heater is recommended below -17°F (-27°C).

Tread Wear Indicators
Tread wear indicators are in the original
equipment tires to help you in determining
when your tires should be replaced.
These indicators are molded into the bottom
of the tread grooves. They will appear as
bands when the tread depth becomes a
1/16 of an inch (1.6 mm). When the tread is
worn to the tread wear indicators, the tire
should be replaced. Refer to “Replacement
Tires” in this section for further information.
Life Of Tire
The service life of a tire is dependent upon
varying factors including, but not limited to:
• Driving style.
• Tire pressure - Improper cold tire inflationpressures can cause uneven wear patterns
to develop across the tire tread. These ab-
normal wear patterns will reduce tread life,
resulting in the need for earlier tire replace-
ment.
• Distance driven.
• Performance tires, tires with a speed rating of V or higher, and Summer tires typically
have a reduced tread life. Rotation of these
tires per the vehicle scheduled mainte-
nance is highly recommended.
WARNING!
Tires and the spare tire should be replaced
after six years, regardless of the remaining
tread. Failure to follow this warning can
result in sudden tire failure. You could lose
control and have a collision resulting in
serious injury or death. Keep dismounted tires in a cool, dry place
with as little exposure to light as possible.
Protect tires from contact with oil, grease,
and gasoline.
Replacement Tires
The tires on your new vehicle provide a bal-
ance of many characteristics. They should be
inspected regularly for wear and correct cold
tire inflation pressures. The manufacturer
strongly recommends that you use tires
equivalent to the originals in size, quality and
performance when replacement is needed.
Refer to the paragraph on “Tread Wear Indi-
cators” in this section. Refer to the Tire and
Loading Information placard or the Vehicle
Certification Label for the size designation of
your tire. The Load Index and Speed Symbol
for your tire will be found on the original
equipment tire sidewall.
See the Tire Sizing Chart example found in
the “Tire Safety Information” section of this
manual for more information relating to the
Load Index and Speed Symbol of a tire.
