The power liftgate may also be opened by pressing the
button located on the overhead console.
When the remote keyless entry transmitter button is
pressed and the “ Lamp Flash ” feature is enabled, the tail
lights will flash to signal that the liftgate is opening or
closing. WARNING!During power operation, personal injury or cargo
damage may occur. Ensure the liftgate travel path is
clear. Make sure the liftgate is closed and latched
before driving away.
NOTE:
• If anything obstructs the power liftgate while it is
closing or opening, the liftgate will automatically
reverse to the closed or open position, provided it
meets sufficient resistance.
• There are also pinch sensors attached to the side of the
liftgate opening. Light pressure anywhere along these
strips will cause the liftgate to return to the open
position.Power Liftgate Switch36 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

How The Airbag System Works
• The Occupant Restraint Controller (ORC) determines
if a frontal collision is severe enough to require the
airbags to inflate. Based on the level of collision
severity, the front control module determines the THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 59

• The Driver and Passenger Airbag/Inflator Units are
located in the center of the steering wheel and the right
side of the instrument panel. When the ORC and
impact sensors detects a collision requiring the air-
bags, it signals the inflator units. A large quantity of
nontoxic gas is generated to inflate the front airbags.
Different airbag inflation rates may be possible based
on collision severity and occupant size. The steering
wheel hub trim cover and the upper right side of the
instrument panel separate and fold out of the way as
the airbags inflate to their full size. The airbags fully
inflate in about 50 – 70 milliseconds. This is about half
of the time it takes to blink your eyes. The airbags then
quickly deflate while helping to restrain the driver and
front passenger.
The driver ’ s and passenger ’ s front airbag gas is vented
through the airbag material towards the instrument
panel. In this way the airbags do not interfere with
your control of the vehicle. • The Side Impact SRS Window Bags are designed to
activate only in certain side collisions. When the ORC
and the side impact sensors (with side impact option)
detects a collision requiring the window bags to
inflate, it signals the inflators on the crash side of the
vehicle. A quantity of nontoxic gas is generated to
inflate the window bag. The inflating window bag
pushes the outside edge of the headliner out of the
way and covers the window. The airbag inflates in
about 30 milliseconds (about one quarter of the time it
takes to blink your eyes) with enough force to injure
you if you are not belted and seated properly, or if
items are positioned in the area where the window bag
inflates. This especially applies to children. The win-
dow bag is only about 3 1
2
inches (9 cm) thick when it
is inflated. THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 61

• When the ORC and the side impact sensors (with side
impact option) detects a collision requiring the Driver
Inflatable Knee Blocker , it signals the inflator unit. A
quantity of nontoxic gas is generated to inflate the
Driver Inflatable Knee Blocker. The Driver Inflatable
Knee Blocker inflates rearward towards the driver ’ s
knees to help protect the knees and position you for
the best interaction with the front airbag. The Driver
Inflatable Knee Blocker fully inflates in about 50
milliseconds, this is only about half of the time it takes
you to blink your eyes. It then quickly deflates while
helping to protect the driver ’ s knees.
• The Knee Impact Bolsters help protect the knees, and
position everyone for the best interaction with the
front airbag.
• If your vehicle contains a Passenger Airbag Disable
indicator light, it will be equipped with the Occupant
Classification System (OCS). The OCS system will classify an occupant into a size category based on
sensor readings from within the seat cushion. Occu-
pants should try to remain in a normally seated
position. If the occupant ’ s weight is transferred to
another object in the vehicle (i.e. feet on the dash-
board), the OCS may not be able to properly approxi-
mate occupant size. Furthermore, the occupant size
may appear to increase or decrease due to objects
hanging on the seat, other passengers pushing on the
seat, or objects lodged underneath the seat. Ensure
that the front passenger seat back does not touch
anything placed on the back seat because this can also
affect occupant classification. Also, if you fold down
the rear seat, check to be sure it doesn ’ t touch the front
passenger seat.
If there is a rapid change in temperature or humidity,
the OCS may not be able to properly approximate
occupant size. If your seat including your trim cover
and cushion needs to be serviced in any way (including62 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Remember, if the PAD indicator light is illuminated the
passenger front airbag will not inflate. For almost all
properly installed child restraints, the “ PAD Indicator
Light ” will be illuminated indicating that the front pas-
senger airbag is turned off and will not inflate. If the
“ PAD Indicator Light ” is not illuminated, DO NOT
assume the airbag is turned off and move the child
restraint to the rear seat. A deploying passenger airbag
can cause death or serious injury to a child in a rear
facing infant seat.
NOTE: Even though this vehicle is equipped with an
Occupant Classification System, children 12 years and
under should always ride buckled up in a rear seat in an
appropriate child restraint.
• The Occupant Classification Module (OCM) — If
Equipped is located beneath the front passenger seat.
The OCM classifies the occupant into one of three size categories based on the input from the Bladder Assem-
bly and Belt Tension Sensor. The size categories in-
clude empty, child, and adult. The OCM sends the
Occupant Classification to the ORC to identify if a
front passenger airbag is allowed. If a fault is present,
the AIRBAG warning light is illuminated.
• The Passenger Airbag Disabled (PAD) Indicator
Light — If Equipped indicates to the driver and
passenger when the airbag is turned OFF in the
presence of a properly seated occupant. When the PAD
indicator light is illuminated, the airbag is OFF. Also,
when the Occupant Classification System detects ei-
ther an empty seat or a weight less than the predeter-
mined occupant threshold, the ORC will not illumi-
nate the PAD indicator light even though the airbag is
turned OFF. When the ocs system detects an adult the
PAD indicator light will be off, and the airbag will be
enabled.64 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

• The Belt Tension Sensor (BTS) — If Equipped is
located at the outboard passenger lap belt anchor. The
BTS generates a signal based on outboard lap belt
tension. This signal is sent to the OCM to ensure that
the resultant bladder pressure increase due to applied
lap belt tension does not cause a small occupant to be
classified as a larger occupant.
• The Bladder Assembly — If Equipped is located
beneath the seat cushion foam. The pressure sensor
sends a signal to the OCM.
The front passenger seat assembly contains critical com-
ponents that affect the front passenger airbag deploy-
ment. Correctly functioning front passenger seat compo-
nents are critical for the Occupant Classification System
(OCS) to properly classify the front passenger and calcu-
late the proper airbag deployment. Do not make any
modifications to the front passenger seat components,
assembly, or to the seat cover. WARNING!Unapproved modifications or service procedures to
the front passenger seat assembly, its related compo-
nents, or seat cover may inadvertently change the
airbag deployment in case of a frontal crash. This
could result in death or serious injury to the front
seat passenger if the vehicle is involved in an acci-
dent. A modified vehicle may not comply with
required Federal Motor Vehicle Safety Standards
(FMVSS).
The following requirements must be strictly adhered to:
• Do not modify the front passenger seat assembly or
components in any way.
• Do not modify the front seat center console or center
position seat in any way. THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 65

• Do not use prior or future model year seat covers not
designated for the specific model being repaired. Al-
ways use the correct seat cover specified for the
vehicle.
• Do not replace the seat cover with an aftermarket seat
cover.
• Do not add a secondary seat cover other than those
approved by DaimlerChrysler/Mopar.
• At no time should any supplemental restraint system
(SRS) component or SRS related component or fas-
tener be modified or replaced with any part except
those which are approved by DaimlerChrysler/
Mopar.
• For replacement of the bladder or seat cover assembly,
always use the DaimlerChrysler service kit which
includes the seat cover and bladder riveted together. If A Deployment Occurs
The airbag system is designed to deploy the airbags
when the ORC and impact sensors detect a moderate-to-
severe collision, to help restrain the vehicle passengers,
and then immediately deflate.
NOTE: A collision that is not severe enough to need
airbag protection will not activate the system. This does
not mean something is wrong with the airbag system.
If you do have a collision which deploys the airbags, any
or all of the following may occur:
• The nylon airbag material may sometimes cause abra-
sions and/or skin reddening to the driver and front
passenger as the airbags deploy and unfold. The
abrasions are similar to friction rope burns or those
you might get sliding along a carpet or gymnasium
floor. They are not caused by contact with chemicals.
They are not permanent and normally heal quickly.66 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

When the driver selects Reverse the system scans for
objects behind the vehicle using four sensors located in
the rear bumper. Objects can be detected from up to 59
inches (150cm). A warning display above the rear win-
dow provides both visible and audible warnings indicat-
ing the range of the object. WARNING!Drivers must be careful when backing up even when
using the Rear Park Assist System. Always check
carefully behind your vehicle, look behind you, and
be sure to check for pedestrians, other vehicles, ob-
structions, and blind spots before backing up. Failure
to do so can result in serious personal injury or death.
The display contains two sets of yellow and red LEDs
that the driver can see in the rear view mirror. Each side
of the vehicle has its own warning LEDs. The system
provides a visual warning by illuminating one or more
yellow LEDs as the vehicle gets closer to the object. As
the vehicle continues to approaches the object, one red
LED is illuminated and the system emits a series of short
beeps. The tone will remain constant and both red LEDs
are illuminated once the vehicle is within 12 inches (30.5
cm) of the object.Rear Park Assist Indicator152 UNDERSTANDING THE FEATURES OF YOUR VEHICLE
