2009 JEEP COMMANDER sensor

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. Light pressure anywhere along these strips
will cause the liftgate to return to the open position.
•The power liftgate must be in the full open position for
any of the buttons to operate. If the liftgate is not fully
open, press the Liftgate button on the Fob with Inte-
grated Key (FOBIK) to fully open the liftgate, and then
press it again to close.
•If the liftgate handle is pulled while the power liftgate is
closing, the liftgate will reverse to the full open position.
•If the liftgate handle is pulled while the power liftgate
is opening, the liftgate motor will disengage to allow
manual operation.
•The power liftgate buttons will not operate if the
vehicle is in gear or the vehicle speed is above 0 mph
(0 km/h).
•The power liftgate will not operate in temperatures
below22°F (30°C) or temperatures above 150°F
(65°C). Be sure to remove any buildup of snow or ice
from the liftgate before pressing any of the power
liftgate switches.
•If the power liftgate encounters multiple obstructions
within the same cycle, the system will automatically
stop and must be opened or closed manually.
•If your liftgate is power closing and you put the
vehicle in gear, the liftgate will continue to power
close. However, vehicle movement may result in a
detection of an obstruction.

Airbag System Components
The airbag system consists of the following:
•Occupant Restraint Control (ORC)
•Airbag Warning Light
•Driver Airbag
•Passenger Airbag
•Side Curtain Airbags above Side Windows
•Side Remote Acceleration Sensors
•Driver Side Seat Track Position Sensor
•Steering Wheel and Column
•Instrument Panel
•Interconnecting Wiring
•Knee Impact Bolsters
•Front Acceleration Sensors
•Driver and Front Passenger Seat Belt Pretensioners
How the Airbag System Works
•
TheOccupant Restraint Control (ORC)determines if
a frontal, side, or rollover collision is severe enough to
require the front and/or side airbags to inflate. The
front airbag inflators are designed to provide different
rates of airbag inflation from direction provided by the
ORC. The ORC will detect roll overs, not rear impacts.
The ORC also monitors the readiness of the electronic
parts of the system whenever the ignition switch is in
the START or ON positions. These include all of the
items listed above except the knee bolster, the instru-
ment panel, and the steering wheel and column. If the
key is in the LOCK position, in the ACC position, or
not in the ignition, the airbags are not on and will not
inflate.

Event Data Recorder (EDR)
In the event of an accident, your vehicle is designed to
record up to five seconds of specific vehicle data parameters
(see the following list) in an event data recorder prior to the
moment of airbag deployment, or near deployment, and up
to a quarter second of high-speed deceleration data during
and/or after airbag deployment or near-deployment. EDR
data are ONLY recorded if an airbag deploys, or nearly
deploys, and are otherwise unavailable.
NOTE:
•A near-deployment event occurs when the airbag
sensor detects severe vehicle deceleration usually in-
dicative of a crash, but not severe enough to warrant
airbag deployment.
•Under certain circumstances, EDR data may not be
recorded (e.g., loss of battery power).
In conjunction with other data gathered during a com-
plete accident investigation, the electronic data may beused by Chrysler LLC and others to learn more about the
possible causes of crashes and associated injuries in order
to assess and improve vehicle performance. In addition
to crash investigations initiated by Chrysler LLC, such
investigations may be requested by customers, insurance
carriers, government officials, and professional crash
researchers, such as those associated with universities,
and with hospital and insurance organizations.
In the event that an investigation is undertaken by
Chrysler LLC (regardless of initiative), the company or its
designated representative will first obtain permission of
the appropriate custodial entity for the vehicle (usually
the vehicle owner or lessee) before accessing the elec-
tronic data stored, unless ordered to download data by a
court with legal jurisdiction (i.e., pursuant to a warrant).
A copy of the data will be provided to the custodial entity
upon request. General data that does not identify par-
ticular vehicles or crashes may be released for incorpo-
ration in aggregate crash databases, such as those main-
tained by the U.S. government and various states. Data of

Rain Sensing Wipers — If Equipped
This feature senses moisture on the windshield and
automatically activates the wipers for the driver. The
feature is especially useful for road splash or overspray
from the windshield washers of the vehicle ahead. Rotate
the end of the multifunction lever to one of five settings
to activate this feature.
The sensitivity of the system can be adjusted with the
multifunction lever. Wiper delay position 1 is the least
sensitive, and wiper delay position 5 is the most sensi-
tive. Setting 3 should be used for normal rain conditions.
Settings 1 and 2 can be used if the driver desires less
wiper sensitivity. Settings 4 and 5 can be used if the
driver desires more sensitivity. Place the wiper switch in
the OFF position when not using the system.
NOTE:
•The rain sensing feature will not operate when the
wiper switch is in the Low or High speed position.
•The rain sensing feature may not function properly when
ice, or dried salt water is present on the windshield.
•Use of Rain-Xor products containing wax or silicone
may reduce rain sensor performance.
•A customer programmable feature in the Electronic
Vehicle Information Center (EVIC) allows the Rain
Sense feature to be turned off. Refer to “Electronic
Vehicle Information Center (EVIC) — Customer-
Programmable Features” in Section 4 of this manual.
The rain sensing system has protection features for the
wiper blades and arms, and will not operate under the
following conditions:
•Low Ambient Temperature— When the ignition is
first turned ON, the rain sensing system will not
operate until the wiper switch is moved, vehicle speed
is greater than 0 mph (0 km/h), or the outside tem-
perature is greater than 32°F (0°C).

active again if the vehicle speed is decreased to speeds
less than approximately 10 mph (16 km/h).
Rear Park Assist Sensors
The four Rear Park Assist Sensors, located in the rear
fascia, monitor the area behind the vehicle that is within
the sensors’ field of view.
The sensors can detect obstacles from approximately 12
to 59 in (30 to 150 cm) from the rear fascia in the
horizontal direction, depending on the location and
orientation of the obstacle and the type of obstacle.
Rear Park Assist Warning Display
The Rear Park Assist Warning Display, located in the
headliner near the flipper glass, provides both visible and
audible warnings to indicate the distance between the
rear fascia and the detected obstacle.When the ignition is turned to the ON position, the
warning display will turn ON all of its LEDs for about
one second. Each side of the warning display has six
yellow and two red LEDs. The vehicle is close to the
obstacle when the red LED is ON.

Cleaning The Rear Park Assist System
Clean the Rear Park Assist Sensors with water, car wash
soap and a soft cloth. Do not use rough or hard cloths. Do
not scratch or poke the sensors. Otherwise, you could
damage the sensors.
REAR CAMERA — IF EQUIPPED
Vehicles with a MyGiG radio may be equipped with a
rearview camera (located on the rear liftgate) that allows
you to see an on-screen image (on the navigation radio
screen) of the rear of your vehicle, whenever the vehicle
is put into REVERSE.
WARNING!
Drivers must be careful when backing up even when
using the Rear Camera System. Always check care-
fully behind your vehicle, and be sure to check for
pedestrians, animals, other vehicles, obstructions, or
blind spots before backing up. You are responsible
for the safety of your surroundings and must con-
tinue to pay attention while backing up. Failure to do
so can result in serious injury or death.
Turning the Rear Camera On or Off
1. Press themenuhard key.
2. Selectsystem set upsoft key.

alternate tires or wheels on the vehicle that prevent the
TPMS from functioning properly. Always check the
TPMS malfunction telltale after replacing one or more
tires or wheels on your vehicle, to ensure that the
replacement or alternate tires and wheels allow the TPMS
to continue to function properly.
CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warning have been established for the tire size
equipped on your vehicle. Undesirable system opera-
tion or sensor damage may result when using re-
placement equipment that is not of the same size,
type, and/or style. Aftermarket wheels can cause
sensor damage. Do not use tire sealant from a can, or
balance beads if your vehicle is equipped with a
TPMS, as damage to the sensors may result.13. Temperature Gauge
The temperature gauge shows engine coolant tempera-
ture. Any reading within the normal range indicates that
the engine cooling system is operating satisfactorily.
The gauge pointer will likely indicate a higher tempera-
ture when driving in hot weather, up mountain grades,
or when towing a trailer. It should not be allowed to
exceed the upper limits of the normal operating range.
CAUTION!
Driving with a hot engine cooling system could
damage your vehicle. If temperature gauge reads “H”
pull over and stop the vehicle. Idle the vehicle with
the air conditioner turned off until the pointer drops
back into the normal range. If the pointer remains on
the “H” and you hear continuous chimes, turn the
engine off immediately, and call an authorized deal-
ership for service.
