Fuel Cut Off Switch
Your vehicle is equipped with a Fuel Cut Off
switch. In the event of an accident, if the
communication network remains intact, and
the power remains intact, depending on the
nature of the event, the Fuel Cut Off Switch may
perform the following functions:
Cut off fuel to the engine and turn off the
engine.
Flash hazard lights as long as the battery has
power or until the hazard light button is
pressed. The hazard lights can be deacti -
vated by pressing the hazard light button.
Turn on the interior lights, which remain on
as long as the battery has power.
Unlock the power door locks.
NOTE:
After an accident, remember to cycle the igni -
tion to the STOP (OFF/LOCK) position and
remove the key from the ignition switch to avoid
draining the battery. Carefully check the vehicle
for fuel leaks in the engine compartment and on
the ground near the engine compartment and
fuel tank before resetting the system and
starting the engine. If there are no fuel leaks or damage to the vehicle electrical devices (e.g.
headlights) after an accident, reset the Fuel Cut
Off Switch by following the procedure described
below. If you have any doubt, contact an autho
-
rized dealer.
Fuel Cut Off Switch Reset Procedure
In order to reset the Fuel Cut Off Switch after an
event push the “A” Button located underneath
the instrument panel on the passenger side.

Fuel Cut Off Switch

Maintaining Your Air Bag System
WARNING!

PERIODIC SAFETY CHECKS YOU SHOULD
M
AKE OUTSIDE THE VEHICLE
Tires
Examine tires for excessive tread wear and
uneven wear patterns. Check for stones, nails,
glass, or other objects lodged in the tread or
sidewall. Inspect the tread for cuts and cracks.
Inspect sidewalls for cuts, cracks, and bulges.
Check the lug nut/bolt torque for tightness.
Check the tires (including spare) for proper cold
inflation pressure.
Lights
Have someone observe the operation of brake
lights and exterior lights while you work the
controls. Check turn signal and high beam
indicator lights on the instrument panel.
Door Latches
Check for proper closing, latching, and locking.
ONLY install floor mats designed to fit your
vehicle. NEVER install a floor mat that
cannot be properly attached and secured to
your vehicle. If a floor mat needs to be
replaced, only use a FCA approved floor
mat for the specific make, model, and year
of your vehicle.
ONLY use the driver’s side floor mat on the
driver’s side floor area. To check for inter -
ference, with the vehicle properly parked
with the engine off, fully depress the accel -
erator, the brake, and the clutch pedal (if
present) to check for interference. If your
floor mat interferes with the operation of
any pedal, or is not secure to the floor,
remove the floor mat from the vehicle and
place the floor mat in your trunk.
ONLY use the passenger’s side floor mat on
the passenger’s side floor area.
ALWAYS make sure objects cannot fall or
slide into the driver’s side floor area when
the vehicle is moving. Objects can become
trapped under accelerator, brake, or clutch
pedals and could cause a loss of vehicle
control.
WARNING! (Continued)
NEVER place any objects under the floor
mat (e.g., towels, keys, etc.). These objects
could change the position of the floor mat
and may cause interference with the accel -
erator, brake, or clutch pedals.
If the vehicle carpet has been removed and
re-installed, always properly attach carpet
to the floor and check the floor mat
fasteners are secure to the vehicle carpet.
Fully depress each pedal to check for inter -
ference with the accelerator, brake, or
clutch pedals then re-install the floor mats.
It is recommended to only use mild soap
and water to clean your floor mats. After
cleaning, always check your floor mat has
been properly installed and is secured to
your vehicle using the floor mat fasteners
by lightly pulling mat.

SERVICING AND MAINTENANCE
SCHEDULED SERVICING
Your vehicle is equipped with an automatic oil
change indicator system. The oil change
indicator system will remind you that it is time to
take your vehicle in for scheduled maintenance.

Based on engine operation conditions, the oil
change indicator message will illuminate in the
instrument cluster. This means that service is
required for your vehicle. Operating conditions
such as frequent short-trips, trailer tow, and
extremely hot or cold ambient temperatures will
influence when the “Oil Change Required”
message is displayed. Severe Operating
Conditions can cause the change oil message to
illuminate as early as 3,500 miles (5,600 km)
since last reset. Have the vehicle serviced as
soon as possible, within the next 500 miles
(805 km).
An authorized dealer will reset the oil change
indicator message after completing the
scheduled oil change. If a scheduled oil change
is performed by someone other than an
authorized dealer, the message can be reset by
referring to the steps described under
Instrument Cluster Display Ú
page 45.
NOTE:
Under no circumstances should oil change
intervals exceed 10,000 miles (16,000 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. Severe Duty All Models

Vehicles that are operated in a dusty and off-road
environment, or predominately at idle or very low
engine RPM are known as Severe Duty vehicles.
It is recommended that you change the engine oil
at 4,000 miles (6,500 km) or 350 hours of
engine run time.

Once A Month Or Before A Long Trip:
Check engine oil level
Check windshield washer fluid level
Check the tire pressures and look for unusual
wear or damage. Rotate at the first sign of
irregular wear, even if it occurs before the oil
indicator system turns on
Check the fluid levels of the coolant reservoir,
brake master cylinder, and power steering
and fill as needed
Check function of all interior and exterior
lights

SERVICING AND MAINTENANCE217
ADDING WASHER FLUID
The fluid reservoir is located in the engine
compartment and should be checked at regular
intervals. Fill the reservoir with windshield
washer solvent (not radiator antifreeze) and
operate the system for a few seconds to flush
out any residual water.
The washer fluid reservoir will hold a full gallon
of fluid when the Low Washer Fluid Light
illuminates.
After the engine has warmed, operate the
defroster for a few minutes to reduce the
possibility of smearing or freezing the fluid on
the cold windshield. Mopar All Weather
Windshield Washer Solution or equivalent, used
with water as directed on the container, aids
cleaning action, reduces the freezing point to
avoid line clogging, and is not harmful to paint
or trim.
MAINTENANCE-FREE BATTERY
Your vehicle is equipped with a
maintenance-free battery. You will never have
to add water, and periodic maintenance is not
required.
PRESSURE WASHING
Cleaning the engine compartment with a high
pressure washer is not recommended.
WARNING!
Commercially available windshield washer
solvents are flammable. They could ignite and
burn you. Care must be exercised when filling
or working around the washer solution.
WARNING!
Battery fluid is a corrosive acid solution and
can burn or even blind you. Do not allow
battery fluid to contact your eyes, skin, or
clothing. Do not lean over a battery when
attaching clamps. If acid splashes in eyes
or on skin, flush the area immediately with
large amounts of water Úpage 203.
Battery gas is flammable and explosive.
Keep flame or sparks away from the
battery. Do not use a booster battery or any
other booster source with an output greater
than 12 Volts. Do not allow cable clamps to
touch each other.
Battery posts, terminals, and related acces -
sories contain lead and lead compounds.
Wash hands after handling.
CAUTION!
It is essential when replacing the cables on
the battery that the positive cable is
attached to the positive post and the nega -
tive cable is attached to the negative post.
Battery posts are marked positive (+) and
negative (-) and are identified on the battery
case. Cable clamps should be tight on the
terminal posts and free of corrosion.
If a “fast charger” is used while the battery
is in the vehicle, disconnect both vehicle
battery cables before connecting the
charger to the battery. Do not use a “fast
charger” to provide starting voltage.
CAUTION!
Precautions have been taken to safeguard all
parts and connections however, the
pressures generated by these machines is
such that complete protection against water
ingress cannot be guaranteed.

TECHNICAL SPECIFICATIONS265
Inspect the wheel mounting surface prior to
mounting the tire and remove any corrosion or
loose particles.

Wheel Mounting Surface

Tighten the lug nuts/bolts in a star pattern until
each nut/bolt has been tightened twice. Ensure
that the socket is fully engaged on the lug nut/
bolt (do not insert it halfway).
Torque Patterns

After 25 miles (40 km), check the lug nut/bolt torque to be sure that all the lug nuts/bolts are
properly seated against the wheel.FUEL REQUIREMENTS
While operating on gasoline with the required
octane number, hearing a light knocking sound
from the engine is not a cause for concern.
However, if the engine is heard making a heavy
knocking sound, see a dealer immediately. Use
of gasoline with a lower than recommended
octane number can cause engine failure and
may void or not be covered by the New Vehicle
Limited Warranty.
Poor quality gasoline can cause problems such
as hard starting, stalling, and hesitations. If you
experience these symptoms, try another brand
of gasoline before considering service for the
vehicle.
3.6L ENGINE
This engine is designed to meet all
emissions regulations and provide
optimum fuel economy and
performance when using high quality
unleaded “Regular” gasoline having a posted
octane number of 87 as specified by the (R+M)/
2 method. The use of higher octane “Premium”
gasoline is not required, as it will not provide
any benefit over “Regular” gasoline in these
engines.
WARNING!
To avoid the risk of forcing the vehicle off the
jack, do not tighten the lug nuts/bolts fully
until the vehicle has been lowered. Failure to
follow this warning may result in personal
injury.
