Window Lockout Button
The Window Lockout button on the driver’s door
allows you to disable the window controls on the
rear doors. To disable the window controls on
the rear doors, press the Window Lockout but-
ton. To enable the window controls, press the
Window Lockout button again.
Wind BuffetingWind buffeting can be described as the percep-
tion of pressure on the ears or a helicopter-type
sound in the ears. Your vehicle may exhibit wind
buffeting with the windows down, or the sunroof
(if equipped) in certain open or partially open
positions. This is a normal occurrence and canbe minimized. If the buffeting occurs with the
rear windows open, then open the front and rear
windows together to minimize the buffeting. If
the buffeting occurs with the sunroof open,
adjust the sunroof opening to minimize the
buffeting.
LIFTGATE
To open the liftgate, pull up on the handle and
lift. Manually unlocking the vehicle doors with
the plunger or a key in the lock cylinder will not
unlock the liftgate.
WARNING!
Driving with the liftgate open can allow poi-
sonous exhaust gases into your vehicle. You
and your passengers could be injured by
these fumes. Keep the liftgate closed when
you are operating the vehicle.
Liftgate Flipper GlassThe liftgate flipper glass is also unlocked when
the liftgate is unlocked. To open the flipper
glass, push up on the window switch located on
the liftgate.
NOTE:
The liftgate flipper glass will not open if the
liftgate is ajar.

Gas props support the liftgate in the open
position. However, because the gas pressure
drops with temperature, it may be necessary to
assist the props when opening the liftgate in
cold weather.
OCCUPANT RESTRAINTS
Some of the most important safety features in
your vehicle are the restraint systems:
•Three-point lap and shoulder belts for the
driver and all passengers
• Advanced Front Air Bags for driver and front
passenger
• Supplemental Active Head Restraints (AHR)
located on top of the front seats (integrated
into the head restraint)
• Supplemental Driver Side Knee Air Bag
• Supplemental Side Air Bag Inflatable Cur-
tains (SABIC) for the driver and passengers
seated next to a window
• Supplemental Seat-Mounted Side Air
Bags (SAB) •
An energy-absorbing steering column and
steering wheel
•
Knee bolsters/blockers for front seat occupant
• Front seat belts incorporate pretensioners
that may enhance occupant protection by
managing occupant energy during an impact
event
• All seat belt systems (except the driver’s and
front passenger) include Automatic Locking
Retractors (ALRs), which lock the seat belt
webbing into position by extending the belt all
the way out and then adjusting the belt to the
desired length to restrain a child seat or
secure a large item in a seat — if equipped
Please pay close attention to the information in
this section. It tells you how to use your restraint
system properly, to keep you and your passen-
gers as safe as possible.
If you will be carrying children too small for
adult-sized seat belts, the seat belts or the ISO-
FIX feature also can be used to hold infant and
child restraint systems. Refer to ISOFIX — Child
Seat Anchorage System for more information.
NOTE:
The Advanced Front Air Bags have a multi-
stage inflator design. This allows the air bag
to have different rates of inflation based on
several factors, including the severity and
type of collision.
Here are some simple steps you can take to
minimize the risk of harm from a deploying air
bag:
1. Children 12 years old and under should
always ride buckled up in a rear seat.
WARNING!
Infants in rear facing child restraints should
never ride in the front seat of a vehicle with a
passenger Advanced Front Air Bag. An air
bag deployment can cause severe injury or
death to infants in that position.
Children that are not big enough to wear the
vehicle seat belt properly (see section on Child
Restraints) should be secured in the rear seat in
child restraints or belt-positioning booster seats.

Driver And Passenger Advanced Front Air
Bag Inflator Units
The Driver and Passenger Advanced Front Air
Bag Inflator Units are located in the center of the
steering wheel and on the right side of the
instrument panel. When the ORC detects a
collision requiring the Advanced Front Air Bags,
it signals the inflator units. A large quantity of
non-toxic gas is generated to inflate the Ad-
vanced Front Air Bags. Different air bag inflation
rates are possible, based on several factors,
including the collision type and severity. The
steering wheel hub trim cover and the upper
right side of the instrument panel separate and
fold out of the way as the air bags inflate to their
full size. The air bags fully inflate in about 50 to
70 milliseconds. This is about half of the time it
takes to blink your eyes. The air bags then
quickly deflate while helping to restrain the
driver and front passenger.
The Advanced Front Air Bag gas is vented
through the vent holes in the sides of the air
bag. In this way, the air bags do not interfere
with your control of the vehicle.Supplemental Driver Side Knee Air Bag
Inflator Unit
The Supplemental Driver Side Knee Air Bag
unit is located in the instrument panel trim
beneath the steering column. When the ORC
detects a collision requiring the air bag, it sig-
nals the inflator units. A large quantity of non-
toxic gas is generated to inflate the Supplemen-
tal Driver Side Knee Air Bag. The trim cover
separates and folds out of the way allowing the
air bag to inflate to the full size. The air bag fully
inflates in about 15 to 20 milliseconds.
Supplemental Seat-Mounted Side Air Bag
(SAB) Inflator Units
The Supplemental Seat-Mounted Side Air Bags
are designed to activate only in certain side
collisions.
The ORC determines if a side collision requires
the side air bags to inflate, based on the severity
and type of collision.
Based on the severity and type of collision, the
side air bag inflator on the crash side of the
vehicle may be triggered, releasing a quantity of
non-toxic gas. The inflating SAB exits through
the seat seam into the space between the
occupant and the door. The SAB fully inflate in
about 10 milliseconds. The side air bag moves
at a very high speed and with such a high force
that it could injure you if you are not seated
properly, or if items are positioned in the area
where the side air bag inflates. This especially
applies to children.
Supplemental Side Air Bag Inflatable
Curtain (SABIC) Inflator Units
During collisions where the impact is confined
to a particular area of the side of the vehicle, the
ORC may deploy the SABIC air bags depend-
ing on the severity and type of collision. In these
events, the ORC will deploy the SABIC only on
the impact side of the vehicle.

Loose Fuel Filler Cap Message
If the vehicle diagnostic system de-
termines that the fuel filler cap is
loose, improperly installed, or dam-
aged, a loose gascap indicator will
display in the EVIC telltale display
area. Refer to “Electronic Vehicle
Information Center (EVIC)” in “Understanding
Your Instrument Panel” for further information.
Tighten the fuel filler cap properly and press the
SELECT button to turn off the message. If the
problem continues, the message will appear the
next time the vehicle is started.
TRAILER TOWING
In this section you will find safety tips and infor-
mation on limits to the type of towing you can
reasonably do with your vehicle. Before towing a
trailer, carefully review this information to tow your
load as efficiently and safely as possible. To maintain warranty coverage, follow the require-
ments and recommendations in this manual con-
cerning vehicles used for trailer towing.
Common Towing DefinitionsThe following trailer towing related definitions
will assist you in understanding the following
information:
Gross Vehicle Weight Rating (GVWR)
The GVWR is the total allowable weight of your
vehicle. This includes driver, passengers, cargo
and tongue weight. The total load must be
limited so that you do not exceed the GVWR.
Refer to “Vehicle Loading/Vehicle Certification
Label” in “Starting and Operating” for further
information.
Gross Trailer Weight (GTW)
The GTW is the weight of the trailer plus the
weight of all cargo, consumables and equip-
ment (permanent or temporary) loaded in or on
the trailer in its
"loaded and ready for operation "
condition. The recommended way to measure
GTW is to put your fully loaded trailer on a
vehicle scale. The entire weight of the trailer
must be supported by the scale.
Gross Combination Weight Rating (GCWR)
The GCWR is the total permissible weight of
your vehicle and trailer when weighed in com-
bination.
NOTE:
The GCWR rating includes a 150 lbs (68 kg)
allowance for the presence of a driver.
Gross Axle Weight Rating (GAWR)
The GAWR is the maximum capacity of the front
and rear axles. Distribute the load over the front
and rear axles evenly. Make sure that you do
not exceed either front or rear GAWR.
278

Trailer Towing Weights (Maximum Trailer Weight Ratings)The following chart provides the maximum trailer weight ratings towable for your given drivetrain.
Engine/TransmissionMax. GTW (Gross Trailer Wt.) —
with Trailer Brake Max. GTW (Gross Trailer Wt.) —
without Trailer Brake Tongue Wt. (See Note)
3.6L Gasoline 5,000 lbs (2 268 kg) 1,653 lbs (750 kg)249 lbs (113 kg)
5.7L Gasoline 7,716 lbs (3 500 kg) 1,653 lbs (750 kg)386 lbs (175 kg)
3.0L Diesel 7,716 lbs (3 500 kg) 1,653 lbs (750 kg)386 lbs (175 kg)
Maximum trailer towing speed is limited to 62 mph (100 km/h) unless local laws require a lower speed.
NOTE:
The trailer tongue weight must be considered as part of the combined weight of occupants and cargo, and should never exceed the weight refer-
enced on the Tire and Loading Information placard. Refer to “Tires – General Information” in “Starting and Operating” for further information.
Trailer And Tongue WeightAlways load a trailer with 60% of the weight in
the front of the trailer. Loads balanced over the
wheels, or heavier in the rear, can cause the
trailer to sway severelyside-to-side which will
cause loss of control of vehicle and trailer.
Failure to load trailers heavier in front is the
cause of many trailer accidents. Never exceed
the maximum tongue weight stamped on your
trailer hitch. Consider the following items when computing
the weight on the front/rear axles of the vehicle:
•
The trailer tongue weight of the trailer.
• The weight of any other type of cargo or
equipment put in or on your vehicle.
• The weight of the driver and all passengers.
281

CAUTION!
•
Failure to properly maintain your vehicle or
perform repairs and service when necessary
could result in more costly repairs, damage
to other components or negatively impact
vehicle performance. Immediately have po-
tential malfunctions examined by an autho-
rized dealer or qualified repair center.
•Your vehicle has been built with improved
fluids that protect the performance and
durability of your vehicle and also allow
extended maintenance intervals. Do not
use chemical flushes in these components
as the chemicals can damage your engine,
transmission, power steering or air condi-
tioning. Such damage is not covered by
the New Vehicle Limited Warranty. If a
flush is needed because of component
malfunction, use only the specified fluid for
the flushing procedure.
Engine Oil – Gasoline Engines
Checking Oil Level
To assure proper lubrication of your vehicle’s
engine, the engine oil must be maintained at the
correct level. The best time to check the engine
oil level is about five minutes after a fully
warmed up engine is shut off or before starting
the engine after it has sat overnight.
Checking the oil while the vehicle is on level
ground will improve the accuracy of the oil level
readings. Maintain the oil level in the SAFE level
range. Adding 1 U.S. Quart (0.95L) of oil when
the level is at the bottom of the SAFE range will
result in the level being at the top of the SAFE
range.
CAUTION!
Overfilling or underfilling the crankcase will
cause aeration or loss of oil pressure. This
could damage your engine. Change Engine Oil
Refer to the “Maintenance Schedule” for the
proper maintenance intervals.
Engine Oil Selection – Non ACEA
Categories
For best performance and maximum protection
under all types of operating conditions, we
recommend you use MOPAR® API Certified
SAE 5W-20 engine oil, meeting the require-
ments of Chrysler Material Standard MS-6395.
American Petroleum Institute (API) Engine
Oil Identification Symbol
This symbol means
that the oil has
been certified by
the American Petro-
leum Institute (API).
The manufacturer
only recommends
API Certified engine
oils.

Points To Remember
NOTE:
When the vehicle is stopped after a few
miles/kilometers of operation, you may ob-
serve vapor coming from the front of the
engine compartment. This is normally a re-
sult of moisture from rain, snow, or high
humidity accumulating on the radiator and
being vaporized when the thermostat opens,
allowing hot engine coolant (antifreeze) to
enter the radiator.
If an examination of your engine compartment
shows no evidence of radiator or hose leaks,
the vehicle may be safely driven. The vapor will
soon dissipate.
•Do not overfill the coolant expansion bottle.
• Check the coolant freeze point in the radiator
and in the coolant expansion bottle. If engine
coolant (antifreeze) needs to be added, the
contents of the coolant expansion bottle must
also be protected against freezing.
• If frequent engine coolant (antifreeze) addi-
tions are required, the cooling system should
be pressure tested for leaks. •
Maintain engine coolant (antifreeze) concen-
tration at a minimum of 50% OAT coolant
(conforming to MS-12106) and distilled water
for proper corrosion protection of your engine
which contains aluminum components.
• Make sure that the coolant expansion bottle
overflow hoses are not kinked or obstructed.
• Keep the front of the radiator clean. If your
vehicle is equipped with air conditioning,
keep the front of the condenser clean.
•
Do not change the thermostat for Summer or
Winter operation. If replacement is ever neces-
sary, install ONLY the correct type thermostat.
Other designs may result in unsatisfactory
engine coolant (antifreeze) performance, poor
gas mileage, and increased emissions.
Brake SystemIn order to assure brake system performance,
all brake system components should be in-
spected periodically. Refer to the “Maintenance
Schedule” for the proper maintenance intervals.
WARNING!
Riding the brakes can lead to brake failure
and possibly a collision. Driving with your
foot resting or riding on the brake pedal can
result in abnormally high brake tempera-
tures, excessive lining wear, and possible
brake damage. You would not have your full
braking capacity in an emergency.
Fluid Level Check – Brake Master Cylinder
The fluid level of the master cylinder should be
checked when performing under the hood ser-
vice, or immediately if the brake system warning
lamp indicates system failure.
The brake master cylinder has a plastic reser-
voir. On the outboard side of the reservoir, there
is a “MAX” dot and a “MIN” dot. The fluid level
must be kept within these two dots. Do not add
fluid above the MAX mark, because leakage
may occur at the cap.
