Fuel System Cautions
CAUTION!
Follow these guidelines to maintain your vehicle’s
performance:
•The use of leaded gasoline is prohibited by Federal
law. Using leaded gasoline can impair engine perfor-
mance and damage the emissions control system.
• An out-of-tune engine or certain fuel or ignition
malfunctions can cause the catalytic converter to
overheat. If you notice a pungent burning odor or
some light smoke, your engine may be out of tune or
malfunctioning and may require immediate service.
Contact your authorized dealer for service assistance.
• The use of fuel additives, which are now being sold
as octane enhancers, is not recommended. Most of
these products contain high concentrations of metha-
nol. Fuel system damage or vehicle performance
problems resulting from the use of such fuels or
additives is not the responsibility of the manufac-
turer and may void or not be covered under the New
Vehicle Limited Warranty. NOTE:
Intentional tampering with the emissions control
system can result in civil penalties being assessed against
you.Carbon Monoxide Warnings
WARNING!
Carbon monoxide (CO) in exhaust gases is deadly.
Follow the precautions below to prevent carbon mon-
oxide poisoning:
• Do not inhale exhaust gases. They contain carbon
monoxide, a colorless and odorless gas, which can
kill. Never run the engine in a closed area, such as a
garage, and never sit in a parked vehicle with the
engine running for an extended period. If the vehicle
is stopped in an open area with the engine running
for more than a short period, adjust the ventilation
system to force fresh, outside air into the vehicle.
• Guard against carbon monoxide with proper main-
tenance. Have the exhaust system inspected every
time the vehicle is raised. Have any abnormal condi-
tions repaired promptly. Until repaired, drive with
all side windows fully open.5
STARTING AND OPERATING 405

ADDING FUEL
CAUTION!
•Damage to the fuel system or emissions control
system could result from using an improper fuel
tank filler tube cap (fuel filler cap). A poorly fitting
cap could let impurities into the fuel system. Also, a
poorly-fitted aftermarket cap can cause the MIL
(Malfunction Indicator Light) to illuminate due to
fuel vapors escaping from the system.
• A poorly fitting fuel filler cap may cause the MIL to
turn on.
• To avoid fuel spillage and overfilling, do not “top
off” the fuel tank after filling.
NOTE: When the fuel nozzle “clicks” or shuts off the fuel
tank is full.
WARNING!
• Never have any smoking materials lit in or near the
vehicle when the gas cap is removed or the tank is
being filled.
(Continued)
WARNING! (Continued)
•Never add fuel to the vehicle when the engine is
running. This is in violation of most state and federal
fire regulations and may cause the MIL to turn on.
NOTE: Tighten the gas cap ¼ turn until you hear one click.
This is an indication that the cap is properly tightened.
If the gas cap is not tightened properly, the Malfunction
Indicator Light will come on. Be sure the gas cap is
tightened every time the vehicle is refueled.
WARNING!
A fire may result if gasoline is pumped into a portable
container that is inside of a vehicle. You could be
burned. Always place gas containers on the ground
while filling.

STARTING AND OPERATING 421

Shifting Into NEUTRAL (N)
Use the following procedure to prepare your vehicle for
recreational towing.
WARNING!
You or others could be injured or killed if you leave the
vehicle unattended with the transfer case in the NEU-
TRAL (N) position without first fully engaging the
parking brake. The transfer case NEUTRAL (N) posi-
tion disengages both the front and rear driveshafts
from the powertrain, and will allow the vehicle to roll,
even if the automatic transmission is in PARK (or
manual transmission is in gear). The parking brake
should always be applied when the driver is not in the
vehicle.
CAUTION!
It is necessary to follow these steps to be certain that
the transfer case is fully in NEUTRAL (N) before
recreational towing to prevent damage to internal
parts.1. Bring the vehicle to a complete stop, with the engine
running. Firmly apply the parking brake.
2. Shift the transmission to NEUTRAL.
3. Press and hold the brake pedal.
4. Depress the clutch pedal on a manual transmission.
5. Shift the transfer case into NEUTRAL: •With manual shift transfer case, shift the transfer case
lever into NEUTRAL (N).
• With electronic shift transfer case, push and hold the
transfer case NEUTRAL (N) button. Some models
have a small, recessed Nbutton (at the center of the
transfer case switches) that must be pressed using a
ballpoint pen or similar object. Other models have a
rectangular NEUTRAL switch, below the rotary trans-
fer case control knob. The NEUTRAL (N) indicator
light will blink while the shift is in progress. The light
will stop blinking (stay on solid) when the shift to
NEUTRAL (N) is complete. After the shift is completed
and the NEUTRAL (N) light stays on, release the
NEUTRAL (N) button.
6. Release the parking brake.
7. Shift the transmission into REVERSE.
426 STARTING AND OPERATING

Before raising the wheel off the ground, make sure that
the jack will not damage surrounding truck parts and
adjust the jack position as required.
NOTE:If the jack will not lower by turning the dial
(thumbwheel) by hand, it may be necessary to use the jack
drive tube in order to lower the jack.
4. By rotating the wheel wrench clockwise, raise the ve- hicle until the wheel just clears the surface.
WARNING!
Raising the vehicle higher than necessary can make the
vehicle unstable. It could slip off the jack and hurt
someone near it. Raise the vehicle only enough to
remove the tire.
5. Remove the wheel nuts and pull the wheel off. Install the spare wheel and wheel nuts with the cone shaped
end of the nuts toward the wheel on single rear wheel
(SRW) models. On dual rear wheel models (DRW) the
lug nuts are a two-piece assembly with a flat face.
Lightly tighten the nuts. To avoid risk of forcing the
vehicle off the jack, do not fully tighten the nuts until the
vehicle has been lowered.
6. Using the wheel wrench, finish tightening the nuts using a crisscross pattern. For the proper lug nut torque
specifications refer to “Wheel and Tire Torque Specifi-
cations” in this section. If in doubt about the correct
tightness, have them checked with a torque wrench by
your authorized dealer or at a service station.

WHAT TO DO IN EMERGENCIES 441

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 automatic trans-
mission 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 your 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 engine is running,
severe catalytic converter damage and power loss
will soon occur. Immediate service is required.
Onboard Diagnostic System (OBD II) Cybersecurity
Your vehicle is required to have an Onboard Diagnostic
system (OBD II) and a connection port to allow access to
information related to the performance of your emissions
controls. Authorized service technicians may need to ac-
cess this information to assist with the diagnosis and
service of your vehicle and emissions system.
WARNING!
• ONLY an authorized service technician should con-
nect equipment to the OBD II connection port in
order to diagnose or service your vehicle.
• If unauthorized equipment is connected to the OBD
II connection port, such as a driver-behavior tracking
device, it may:
• Be possible that vehicle systems, including safety
related systems, could be impaired or a loss of
vehicle control could occur that may result in an
accident involving serious injury or death.
• Access, or allow others to access, information
stored in your vehicle systems, including personal
information.
For further information, refer to “Cybersecurity” in “Mul-
timedia”.
454 MAINTAINING YOUR VEHICLE

•For grease stains, apply Mopar Multi-Purpose Cleaner
to a clean, damp cloth and remove stain. Use a fresh,
damp towel to remove soap residue.
• Do not use any harsh solvents or any other form of
protectants on Stain Repel products.
Interior Care
Use Mopar Total Clean to clean fabric upholstery and
carpeting.
Use Mopar Total Clean to clean vinyl upholstery.
Mopar Total Clean is specifically recommended for leather
upholstery.
Your leather upholstery can be best preserved by regular
cleaning with a damp soft cloth. Small particles of dirt can
act as an abrasive and damage the leather upholstery and
should be removed promptly with a damp cloth. Stubborn
soils can be removed easily with a soft cloth and Mopar
Total Clean. Care should be taken to avoid soaking your
leather upholstery with any liquid. Please do not use
polishes, oils, cleaning fluids, solvents, detergents, or
ammonia-based cleaners to clean your leather upholstery.
Application of a leather conditioner is not required to
maintain the original condition.
WARNING!
Do not use volatile solvents for cleaning purposes.
Many are potentially flammable, and if used in closed
areas they may cause respiratory harm.
CAUTION!
• Direct contact of air fresheners, insect repellents,
suntan lotions, or hand sanitizers to the plastic,
painted, or decorated surfaces of the interior may
cause permanent damage. Wipe away immediately.
• Damage caused by these type of products may not be
covered by your New Vehicle Limited Warranty.
• Do not use Alcohol and Alcohol-based and/or Keton
based cleaning products to clean leather seats, as
damage to the seat may result.
Cleaning Headlights
Your vehicle is equipped with plastic headlights and fog
lights that are lighter and less susceptible to stone breakage
than glass headlights.
Plastic is not as scratch resistant as glass and therefore
different lens cleaning procedures must be followed.
