ONBOARD DIAGNOSTIC SYSTEM — OBD II
Your vehicle is equipped with a sophisticated
Onboard Diagnostic system called OBD II. This
system monitors the performance of the
emissions, engine, and transmission control
systems. When these systems are operating
properly, your vehicle will provide excellent
performance and fuel economy, as well as
engine emissions well within current
government regulations. If any of these systems require service, the OBD
II system will turn on the Malfunction Indicator
Light (MIL). It will also store diagnostic codes
and other information to assist your service
technician in making repairs. Although your
vehicle will usually be drivable and not need
towing, see an authorized dealer for service as
soon as possible.
CAUTION!
Prolonged driving with the MIL on could
cause further damage to the emission
control system. It could also affect fuel
economy and driveability. The vehicle must
be serviced before any emissions tests can
be performed.
If the MIL is flashing while the vehicle is
running, severe catalytic converter damage
and power loss will soon occur. Immediate
service is required.

3. Push the ENGINE START/STOP button a second time to place the ignition to the RUN
mode.
4. Push the ENGINE START/STOP button a third time to return the ignition to the OFF
mode.
If Engine Fails To Start
If the engine fails to start after you have
followed the “Normal Starting” procedure, it
may be flooded. Push the accelerator pedal all
the way to the floor and hold it there while the
engine is cranking. This should clear any excess
fuel in case the engine is flooded.
The starter motor will engage automatically, run
for 10 seconds, and then disengage. Once this
occurs, release the accelerator pedal and the
brake pedal, wait 10 to 15 seconds, then repeat
the “Normal Starting” procedure.
If the engine has been flooded, it may start to
run, but not have enough power to continue
running when the ignition button/key is
released. If this occurs, continue cranking with
the accelerator pedal pushed all the way to the
floor. Release the accelerator pedal and the ignition button/key once the engine is running
smoothly.
If the engine shows no sign of starting after a
10 second period of engine cranking with the
accelerator pedal held to the floor, wait 10 to
15 seconds, then repeat the “Normal Starting”
procedure.NORMAL STARTING USING ENGINE

To Turn On The Engine Using The ENGINE
START/STOP Button

1. The transmission must be in PARK (P).

2. Press and hold the brake pedal while
pushing the ENGINE START/STOP button
once.
WARNING!
Never pour fuel or other flammable liquid
into the throttle body air inlet opening 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 equipped with an
automatic transmission cannot be started
this way. Unburned 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 Úpage 386.
CAUTION!
To prevent damage to the starter, do not
crank the engine for more than 10 seconds at
a time. Wait 10 to 15 seconds before trying
again.
WARNING! (Continued)

148STARTING AND OPERATING
NOTE:
Use of Climatized ULSD Fuel or Number
1 ULSD Fuel results in a noticeable decrease
in fuel economy.
Climatized ULSD Fuel is a blend of Number
2 ULSD and Number 1 ULSD Fuels which
reduces the temperature at which wax crys -
tals form in fuel.
The fuel grade should be clearly marked on
the pump at the fuel station.
The engine requires the use of ULSD Fuel.
Use of incorrect fuel could result in engine
and exhaust system damage Ú page 471.
If Climatized or diesel Number 1 ULSD Fuel is
not available, and you are operating below
(20°F/-6°C), in sustained arctic conditions,
Mopar Premium Diesel Fuel Treatment (or
equivalent) is recommended to avoid gelling
(see Fuel Operating Range Chart).
Engine Oil Usage
For the correct engine oil viscosity Úpage 475.
Winter Front Cover

Winter Front Cover

A Winter front or cold weather cover can be
used in ambient temperatures below 32°F
(0°C), especially during extended idle
conditions. This cover is equipped with four
flaps for managing total grille opening in varying
ambient temperatures. If a Winter front or cold
weather cover is to be used the flaps should be
in the full open position to allow air flow to the
cooling module and automatic transmission oil
cooler. When ambient temperatures drop below
0°F (-17°C) the four flaps need to be closed. A
suitable cold weather cover is available from a
Mopar dealer.
Engine Warm-Up
Avoid full throttle operation when the engine is
cold. When starting a cold engine, bring the
engine up to operating speed slowly to allow the
oil pressure to stabilize as the engine warms up.
If temperatures are below 32°F (0°C), operate
the engine at moderate speeds for five minutes
before full loads are applied.
ENGINE IDLING
Avoid prolonged idling, long periods of idling
may be harmful to your engine because
combustion chamber temperatures can drop so
low that the fuel may not burn completely.
Incomplete combustion allows carbon and
varnish to form on piston rings, cylinder head
valves, and injector nozzles. Also, the unburned
fuel can enter the crankcase, diluting the oil
and causing rapid wear to the engine.
STOPPING THE ENGINE
After full load operation, idle the engine for a
few minutes before shutting it down. This idle
period will allow the lubricating oil and coolant
to carry excess heat away from the
turbocharger. Refer to the following chart for
proper engine shutdown.
