STARTING AND OPERATING225
The fuel grade should be clearly marked on
the pump at the fuel station.
The engine requires the use of “Ultra Low
Sulfur Diesel Fuel”. Use of incorrect fuel
could result in engine and exhaust system
damage. Refer to “Fuel Requirements” in
“Technical Specifications” for further infor -
mation.
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).
Under some circumstances increased engine
noise may be audible in the seconds
following a cold start. This is most likely to
occur when using fuel that isn't blended for
the ambient temperature present. This may
occur on an unseasonably cold day or when a
truck is fueled in a warmer climate and driven
to a colder climate. The noise can typically be
prevented by using Mopar Premium Diesel
Fuel Treatment as recommended (see Fuel
Operating Range Chart).
Engine Oil Usage
Refer to “Dealer Service” in “Servicing And
Maintenance” for the correct engine oil
viscosity.
Winter Front Cover Usage
A Winter front or cold weather cover is to 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
left in the full open position to allow air flow to
the charge air cooler 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 your Mopar dealer.
Battery Blanket Usage
A battery loses 60% of its cranking power as the
battery temperature decreases to 0°F (-18°C).
For the same decrease in temperature, the
engine requires twice as much power to crank
at the same RPM. The use of 120 VAC powered
battery blankets will greatly increase starting capability at low temperatures. Suitable battery
blankets are available from an authorized
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.
NOTE:
High-speed, no-load running of a cold engine
can result in excessive white smoke and poor
engine performance. No-load engine speeds
should be kept under 1,000 RPM during the
warm-up period, especially in cold ambient
temperature conditions.
Your vehicle is equipped with an engine warm
up protection feature that may limit engine
performance after cold starting at low ambient
temperatures. The length of time engine speed
is limited is dependent upon engine coolant
temperature. Engine speed may be briefly
limited to 1000 RPM after starting with coolant
temperature below freezing conditions, and
may be limited to 1000 RPM for up to
approximately 2 minutes under more severe
cold conditions.

OPERATING YOUR WINCH General Information
Practice using your winch before you get stuck.
Some key points to remember when using your
winch are:
Always take your time to assess the situation
and plan your pull carefully.
Always take your time when using a winch.
Use the right equipment for the situation.
Always wear leather gloves and do not allow
the synthetic rope to slip through your hands
when handling the rope.
Only the operator should handle the synthetic
rope and remote control.
Think safety at all times.
Vehicle Recovery Using The Winch
WARNING!
Failure to observe any of these warnings
regarding proper winch usage may result in
severe injury.
Always use supplied hook strap to hold the
hook when spooling wire rope in or out.
Never use as a hoist.
Never use to move persons.
Never exceed winch or synthetic rope rated
capacity.
Always wear heavy leather gloves when
handling the synthetic rope.
Never touch synthetic rope or hook while in
tension or under load.
Never engage or disengage clutch if winch
is under load, synthetic rope is in tension,
or rope drum is moving.
Always stand clear of synthetic rope and
load and keep others away during winching.
Always keep hands and clothing clear of the
synthetic rope, hook and fairlead opening
during operation and when spooling.
Never wrap synthetic rope back onto itself.
Always use a choker chain, wire choker
rope or tree trunk protector on the anchor.
Never attach a recovery strap to the winch
hook to increase the length of a pull.
Never attempt to tow a vehicle with the
recovery strap attached directly to the
winch hook.
Never use bungee or kinetic straps that
develop tremendous and potentially
dangerous amounts of force when
stretched.
Always disconnect the remote control when
not in use.
Never winch when there are less than
10 wraps of synthetic rope around the
winch drum.
Always pass remote control through a
window to avoid pinching lead in door,
when using remote inside a vehicle.
Never leave the remote control plugged
into the winch while free spooling, rigging or
sitting idle.
WARNING! (Continued)
CAUTION!
Always know your winch: Take the time to
fully read and understand the included
Installation and Operations Guide, and
Basic Guide to Winching Techniques, in
order to understand your winch and the
winching operation.

278STARTING AND OPERATING
synthetic rope tends to stack up at one end of
the drum. This stack can become large
enough to cause serious damage to the
winch. So, line up pulls as straight ahead as
possible and stop winching if the synthetic
rope comes close to the tie rods or mounting
plate. To fix an uneven stack, spool out that
section of the rope and reposition it to the
opposite end of the drum, which will free up
space for continued winching.
15. Secure vehicle. Once recovery of the vehicle is complete, be sure to secure the vehicle's
brakes and shift the transmission to PARK.
Release tension in the synthetic rope.
16. Disconnect the synthetic rope, and disconnect from the anchor.
17. Rewind the synthetic rope. The person handling the synthetic rope should walk the
rope in and not let it slide through the hand,
control the winch at all times.
Rewinding The Synthetic Rope

NOTE:
How to spool under no load: Arrange the remote
control lead so it cannot be caught in the winch.
Arrange the synthetic rope so it will not kink or
tangle when spooled. Be sure any synthetic
rope already on the spooling drum is wound
tightly and evenly layered. Tighten and
straighten the layer if necessary. Keep the
synthetic rope under light tension and spool the
rope back and onto the winch drum in even
layers. Stop frequently to tighten and straighten
the layers as necessary. Repeat this process until the winch hook is the same distance as the
full length of the remote control from the winch.
Pinch the hook between your thumb and fore
-
finger and attach the hook strap. Hold the hook
strap between the thumb and forefinger to keep
tension on the synthetic rope. Walk the
synthetic rope towards the fairlead, carefully
spooling in the remaining rope by pulsing the
remote control switch.
18. Store the hook on the most outboard loop of
the hawse fairlead.

Hook In Stored Position

19. Disconnect the remote control. Disconnect the remote control cord from the control box
and store in a clean and dry place. Winching
operations are now complete. Put the cap
on the solenoid plug-in.
WARNING!
To prevent serious injury, NEVER put your
fingers inside the hook area as you are
powering-in.
