STARTING AND OPERATING263
Winching (Refer To “Winch Operation” For
Additional Information) – Winching is most
commonly used in the following situations:
there is no support vehicle available, a high
controlled force is required to recover the
vehicle, there is a high risk of environmental
or vehicle damage, or where nothing else
seems to work. A winch can deliver a high
pulling force with a great deal of control. It
allows you to walk the vehicle out of the situ -
ation in a slow controlled manner. This
control works well for avoiding further vehicle
damage. Once you decide it is time to use the
winch look for a good anchor point. It needs
to be strong enough to hold more than the vehicle's weight and provide a direction of
pull as straight as possible. Use block and
tackle if necessary to improve the angle of
pull or increase the winch's pulling force. If
the anchor point is a tree use a strap around
its base and hook the cable to the strap. If it
is another vehicle, then place that vehicle in
PARK and block the front tires. If you cannot
find an anchor point within reach try using
your spare tire by burying it. Once you have
determined an anchor point hook up the
cable, ensuring there are a least five wraps of
cable left on the drum, and place a floor mat
or something else over the strung out cable.
Placing something over the strung out cable
helps keep the cable on the ground if it
breaks. Next, place the vehicle in FIRST gear
and apply a very light throttle as you power
the winch in. Be careful not to allow slack in
the cable as you recover the vehicle. Do not
try to guide the cable into the drum. If it starts
to bunch up on one end, let it. You can
re-spool the cable afterwards. Never use a
winch cable as a tow strap and always stand
back while winching.
After Driving Off-Road
Off-road operation puts more stress on your
vehicle than does most on-road driving. After
going off-road, it is always a good idea to check
for damage. That way you can get any problems
taken care of right away and have your vehicle
ready when you need it.
Completely inspect the underbody of your
vehicle. Check tires, body structure, steering,
suspension, and exhaust system for damage.
Inspect the radiator for mud and debris and
clean as required.
WARNING!
Never use tow straps with end hooks or link
two straps with a clevis pin. These heavy
metal objects could become projectiles if a
strap breaks, which could cause severe
injury. Never leave more than 2 to 3 feet
(0.60 to 1 meter) of slack in the strap. More
slack than this greatly increases the risk of
injury and vehicle damage. Always keep
everyone at least 30 feet (9 meters) away
from a strapping or winching situation.
WARNING!
Winch cables are under high tension when in
use and can become a projectile if they fail.
Never stand over or straddle the winch cable.
Never jerk or overload the winch cable. Never
stand in front of the vehicle while winching.
Failure to follow these instructions can result
in serious or fatal injury.

396SERVICING AND MAINTENANCE
DEALER SERVICE
An authorized dealer has the qualified service
personnel, special tools, and equipment to
perform all service operations in an expert
manner. Service Manuals are available which
include detailed service information for your
vehicle. Refer to these Service Manuals before
attempting any procedure yourself.
NOTE:
Intentional tampering with emissions control
systems may void your warranty and could
result in civil penalties being assessed against
you.
Engine Oil
Change Engine Oil — Gas Engine
The oil change indicator system will remind you
that it is time to take your vehicle in for sched -
uled maintenance. Refer to “Scheduled
Servicing” in this chapter for further informa -
tion.
NOTE:
Under no circumstances should oil change
intervals exceed 8,000 miles (13,000 km),
12 months or 350 hours of engine run time,
whichever comes first. The 350 hours of engine
run or idle time is generally only a concern for
fleet customers.
Change Engine Oil — Diesel Engine
Refer to the “Scheduled Servicing” for the
proper maintenance intervals.
Engine Oil Selection — Gas Engine
For best performance and maximum protection
under all types of operating conditions, the
manufacturer only recommends engine oils that are API Certified and meet the require
-
ments of FCA Material Standard MS-12633.
Engine Oil Selection — Diesel Engine
For best performance and maximum protection
under all types of operating conditions, the
manufacturer only recommends engine oils
that are API CK-4 certified and meet the require -
ments of FCA US LLC. Use Mopar or an equiva -
lent oil meeting FCA Material Standard
MS-10902. Products meeting Cummins CES
20081 may also be used. The identification of
these engine oils are typically located on the
back of the oil container.
American Petroleum Institute (API) Engine Oil
Identification Symbol — Gas Engine
This symbol means that the oil has
been certified by the American Petro -
leum Institute (API). The manufac -
turer only recommends API Certified
engine oils.
This symbol certifies 0W-20, 5W-20, 0W-30,
5W-30 and 10W-30 engine oils.
WARNING!
You can be badly injured working on or
around a motor vehicle. Only do service work
for which you have the knowledge and the
proper equipment. If you have any doubt
about your ability to perform a service job,
take your vehicle to a competent mechanic.

American Petroleum Institute (API) Engine Oil
Identification Symbol — Diesel Engine
This symbol means that the oil has
been certified by the American Petro -
leum Institute (API). The manufac -
turer only recommends API Certified
engine oils.
Oils with a high ash content may produce
damaging deposits on cylinder head valves
and/or aftertreatment system damage. A
maximum sulfated ash content of 1.00 mass %
is recommended for all oil used in the engine.
The same oil change interval is to be followed
for synthetic oil as for petroleum based oil. Also,
synthetic oil must meet the same performance
specifications as petroleum oil.
Engine Oil Viscosity — Gas Engine
Use Mopar SAE 0W-40 engine oil approved to
FCA Material Standard MS-12633 such as
Pennzoil Ultra equivalent is recommended for
all operating temperatures.
The engine oil filler cap also shows the recom -
mended engine oil viscosity for your engine. For
information on engine oil filler cap location,
refer to the “Engine Compartment” illustration
in this section.
Lubricants which do not have both the engine
oil certification mark and the correct SAE
viscosity grade number should not be used.
Engine Oil Viscosity — Diesel Engine
In ambient temperatures above 0°F (-18°C),
we recommend you use SAE 10W-30 engine oil
such as Mopar, Shell Rotella and Shell Rimula
that meets FCA Material Standard MS-10902
and the API CK-4 engine oil category is required.
Products meeting Cummins CES 20081 may also be used. The identification of these engine
oils is typically located on the back of the oil
container.
In ambient temperatures below 0°F (-18°C), we
recommend you use SAE 5W-40
synthetic
engine oil such as Mopar, Shell Rotella and
Shell Rimula that meets FCA Material Standard
MS-10902 and the API CK-4 engine oil category
is required.
Engine oil not designated by the FCA or
Cummins Material Standards and API CK-4
should not be used, as engine and exhaust
system durability may be compromised. The
CAUTION!
Do not use chemical flushes in your engine oil
as the chemicals can damage your engine.
Such damage is not covered by the New
Vehicle Limited Warranty.

CAUTION!
Failure to use SAE 5W-40 synthetic engine oil
in ambient temperatures below 0°F (-18°C)
could result in severe engine damage.
