could result in evident white smoke. This condition
will disappear as the engine warms up.
AUTOMATIC TRANSMISSION
Start the engine with the transmission gear
selector in the PARK (P) position. Apply the brake
before shifting to any driving range.
EXTREME COLD WEATHER
The cartridge block heater clips into the engine
block near the water jacket and transfers heat to
the coolant. 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 temperatures
under -20°F (-28°C).
NOTE:The engine block heater and heater cord are
factory installed options. If your vehicle is not
equipped, engine block heaters and heater cords
are available from an 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 STARTING
Observe the instrument cluster lights when
starting the engine.
NOTE:Normal starting of either a cold or a warm engine is
obtained without pumping or pressing the accel -
erator 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”

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 position. A 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.
CAUTION!
The engine is allowed to crank as long as
25 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 before you drain the
water from the fuel filters to avoid engine
damage Ú page 368.

Observe the following when the diesel engine is
operating:
All message center lights are off.
Malfunction Indicator Light (MIL) is off.
Engine Oil Pressure telltale is not illuminated.
Voltmeter operation.
The voltmeter may show a gauge fluctuation at
various engine temperatures. This is caused by the
glow plug heating system. The number of cycles
and the length of the cycling operation is controlled by the engine control module. Glow plug heater
operation can run for several minutes. Once the
heater operation is complete the voltmeter needle
will stabilize.
COLD WEATHER PRECAUTIONS

STARTING AND OPERATING195
(Continued)
The DEF gauge may also not immediately
update after a refill if the temperature of the
DEF fluid is below 12°F (-11°C). The DEF
line heater will possibly warm up the DEF
fluid and allow the gauge to update after a
period of run time. Under very cold condi -
tions, it is possible that the gauge may not
reflect the new fill level for several drives.
Excessive overfilling of the DEF tank can
result in a MIL lamp/fault code and inaccu-
rate level readings.
Refilling With Nozzles
You can fill up at any DEF distributor.
Proceed as follows:
Insert the DEF nozzle in the filler, start
refilling and stop refilling at the first shut-off
(the shut-off indicates that the DEF tank is
full). Do not proceed with the refilling, to
prevent spillage of DEF.
Extract the nozzle.
Refilling With Containers
Proceed as follows:
Check the expiration date.
Read the advice for use on the label before
pouring the content of the bottle into the
DEF tank.
If systems which cannot be screwed in
(e.g. tanks) are used for refilling, after the
indication appears on the instrument panel
display Úpage 121 fill the DEF tank with no
more than 2 gal (8 L).
If containers which can be screwed to the
filler are used, the reservoir is full when the
DEF level in the container stops pouring out.
Do not proceed further.
3. Stop filling the DEF tank immediately when any of the following happen: DEF stops flowing
from the fill bottle into the DEF fill inlet, DEF
splashes out the fill inlet, or a DEF pump
nozzle automatically shuts off.
4. Reinstall cap onto DEF fill inlet.
VEHICLE LOADING
CERTIFICATION LABEL
As required by National Highway Traffic Safety
Administration regulations, your vehicle has a
certification label affixed to the driver's side door or
pillar.
CAUTION!
To avoid DEF spillage, and possible damage to
the DEF tank from overfilling, do not “top off”
the DEF tank after filling.
DO NOT OVERFILL. DEF will freeze below 12ºF
(-11ºC). The DEF system is designed to work in
temperatures below the DEF freezing point,
however, if the tank is overfilled and freezes,
the system could be damaged.
When DEF is spilled, clean the area immedi -
ately with water and use an absorbent mate -
rial to soak up the spills on the ground.
Do not attempt to start your engine if DEF is
accidentally added to the diesel fuel tank as it
can result in severe damage to your engine,
including but not limited to failure of the fuel
pump and injectors.
Never add anything other than DEF to the tank
– especially any form of hydrocarbon such as
diesel fuel, fuel system additives, gasoline, or
any other petroleum-based product. Even a
very small amount of these, less than
100 parts per million or less than 1 oz. per
78 gal (295 L) will contaminate the entire DEF
system and will require replacement. If
owners use a container, funnel or nozzle when
refilling the tank, it should either be new or
one that is has only been used for adding DEF.
Mopar® provides an attachable nozzle with its
DEF for this purpose.
CAUTION!
