2018 JEEP COMPASS sensor

WARNING!
Rear Cross Path Detection (RCP) is not a
back up aid system. It is intended to be
used to help a driver detect an oncoming
vehicle in a parking lot situation. Drivers
must be careful when backing up, even
when using RCP. Always check carefully
behind your vehicle, look behind you, and
be sure to check for pedestrians, animals,
other vehicles, obstructions, and blind
spots before backing up. Failure to do so
can result in serious injury or death.
Modes Of Operation
Three selectable modes of operation are
available in the Uconnect System. Refer to
“Uconnect Settings” in “Multimedia” in the
Owner’s Manual for further information.
Blind Spot Alert Lights Only (Default Setting)
When operating in Blind Spot Alert mode, the
BSM system will provide a visual alert in the
appropriate side view mirror based on a de-
tected object. However, when the system is
operating in Rear Cross Path (RCP) mode, thesystem will respond with both visual and
audible alerts when a detected object is pres-
ent. Whenever an audible alert is requested,
the radio is muted.
Blind Spot Alert Lights/Chime
When operating in Blind Spot Alert Lights/
Chime mode, the BSM system will provide a
visual alert in the appropriate side view mirror
based on a detected object. If the turn signal
is then activated, and it corresponds to an
alert present on that side of the vehicle, an
audible chime will also be sounded. When-
ever a turn signal and detected object are
present on the same side at the same time,
both the visual and audible alerts will be
issued. In addition to the audible alert the
radio (if on) will also be muted.
NOTE:
Whenever an audible alert is requested by the
BSM system, the radio is also muted.
When the system is in RCP, the system shall
respond with both visual and audible alerts
when a detected object is present. Wheneveran audible alert is requested, the radio vol-
ume is reduced. Turn/hazard signal status is
ignored; the RCP state always requests the
chime.
Blind Spot Alert Off
When the BSM system is turned off there will
be no visual or audible alerts from either the
BSM or RCP systems.
NOTE:
The BSM system will store the current oper-
ating mode when the vehicle is shut off. Each
time the vehicle is started the previously
stored mode will be recalled and used.
Blocked Sensor
If the system detects degraded performance
due to contamination or foreign objects, a
message will warn you of a blocked sensor
and the warning indicators in side view mir-
rors will be illuminated. The warning indica-
tors will remain illuminated until blockage
clearing conditions are met. First clear the
fascia area around the sensors of the block-
age. After removing the blockage, reset the
system by cycling the ignition from ON to
OFF and then back ON.

Forward Collision Warning (FCW) With
Mitigation — If Equipped
Forward Collision Warning (FCW) With Miti-
gation Operation
The Forward Collision Warning (FCW) system
with mitigation provides the driver with au-
dible warnings, visual warnings (within the
instrument cluster display), and may apply a
brake jerk to warn the driver when it detects a
potential frontal collision. The warnings and
limited braking are intended to provide the
driver with enough time to react, avoid or
mitigate the potential collision.
NOTE:
FCW monitors the information from the for-
ward looking sensors as well as the Electronic
Brake Controller (EBC), to calculate the prob-
ability of a forward collision. When the sys-
tem determines that a forward collision is
probable, the driver will be provided with
audible and visual warnings and may provide
a brake jerk warning.
If the driver does not take action based upon
these progressive warnings, then the system
will provide a limited level of active braking tohelp slow the vehicle and mitigate the poten-
tial forward collision. If the driver reacts to
the warnings by braking and the system de-
termines that the driver intends to avoid the
collision by braking but has not applied suf-
ficient brake force, the system will compen-
sate and provide additional brake force as
required.
If a Forward Collision Warning with Mitigation
event begins at a speed below 26 mph
(42 km/h), the system may provide the maxi-
mum braking possible to mitigate the poten-
tial forward collision. If the Forward Collision
Warning with Mitigation event stops the ve-
hicle completely, the system will hold the
vehicle at standstill for two seconds and then
release the brakes.
When the system determines a collision with
the vehicle in front of you is no longer prob-
able, the warning message will be deacti-
vated.
NOTE:
• The minimum speed for FCW activation is
1 mph (2 km/h).• The FCW alerts may be triggered on objects
other than vehicles such as guard rails or
sign posts based on the course prediction.
This is expected and is a part of normal
FCW activation and functionality.
• It is unsafe to test the FCW system. To
prevent such misuse of the system, after
four Active Braking events within a key
cycle, the Active Braking portion of FCW
will be deactivated until the next key cycle.
• The FCW system is intended for on-road use
only. If the vehicle is taken off-road, the
FCW system should be deactivated to pre-
vent unnecessary warnings to the
surroundings.
WARNING!
Forward Collision Warning (FCW) is not
intended to avoid a collision on its own,
nor can FCW detect every type of potential
collision. The driver has the responsibility
to avoid a collision by controlling the ve-
hicle via braking and steering. Failure to
follow this warning could lead to serious
injury or death.

For example, your vehicle may have a recom-
mended cold (parked for more than three
hours) placard pressure of 33 psi (227 kPa).
If the ambient temperature is 68°F (20°C)
and the measured tire pressure is 28 psi
(193 kPa), a temperature drop to 20°F (-7°C)
will decrease the tire pressure to approxi-
mately 24 psi (165 kPa). This tire pressure is
low enough to turn on the “Tire Pressure
Monitoring Telltale Light.” Driving the ve-
hicle may cause the tire pressure to rise to
approximately 28 psi (193 kPa), but the “Tire
Pressure Monitoring Telltale Light” will still
be on. In this situation, the “Tire Pressure
Monitoring Telltale Light” will turn off only
after the tires are inflated to the vehicle’s
recommended cold placard pressure value.
NOTE:
When filling warm tires, the tire pressure may
need to be increased up to an additional 4 psi
(30 kPa) above the recommended cold plac-
ard pressure in order to turn the Tire Pressure
Monitoring Telltale Light off.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 replacement equipment that is not
of the same size, type, and/or style. The
TPM sensor is not designed for use on
aftermarket wheels and may contribute
to a poor overall system performance or
sensor damage. Customers are encour-
aged to use OEM wheels to assure
proper TPM feature operation.
• Using aftermarket tire sealants may
cause the Tire Pressure Monitoring Sys-
tem (TPMS) sensor to become inoper-
able. After using an aftermarket tire
sealant it is recommended that you take
your vehicle to your authorized dealer to
have your sensor function checked.
• After inspecting or adjusting the tire
pressure always reinstall the valve stem
cap. This will prevent moisture and dirt
CAUTION!
from entering the valve stem, which
could damage the TPMS sensor.
NOTE:
• The TPMS is not intended to replace nor-
mal tire care and maintenance, or to pro-
vide warning of a tire failure or condition.
• The TPMS should not be used as a tire
pressure gauge while adjusting your tire
pressure.
• Driving on a significantly underinflated tire
causes the tire to overheat and can lead to
tire failure. Underinflation also reduces
fuel efficiency and tire tread life, and may
affect the vehicle’s handling and stopping
ability.
• The TPMS is not a substitute for proper tire
maintenance, and it is the driver’s respon-
sibility to maintain correct tire pressure
using an accurate tire pressure gauge, even
if underinflation has not reached the level
to trigger illumination of the “Tire Pressure
Monitoring Telltale Light”.
SAFETY
92

• Seasonal temperature changes will affect
tire pressure, and the TPMS will monitor
the actual tire pressure in the tire.
Base System
The Tire Pressure Monitor System (TPMS)
uses wireless technology with wheel rim
mounted electronic sensors to monitor tire
pressure levels. Sensors, mounted to each
wheel as part of the valve stem, transmit tire
pressure readings to the receiver module.
NOTE:
It is particularly important for you to check
the tire pressure in all of the tires on your
vehicle monthly and to maintain the proper
pressure.
The TPMS consists of the following compo-
nents:
• Receiver Module
• Four Tire Pressure Monitoring Sensors
• Tire Pressure Monitoring Telltale Light
Tire Pressure Monitoring Low Pressure
Warnings
The “Tire Pressure Monitoring Tell-
tale Light” will illuminate in the in-
strument cluster, a “LOW TIRE
PRESSURE” message will display in the in-
strument cluster and a chime will sound
when tire pressure is low in one or more of the
four active road tires. Should this occur, you
should stop as soon as possible, check the
inflation pressure of each tire on your vehicle,
and inflate each tire to the vehicle’s recom-
mended cold placard pressure value. Once
the system receives the updated tire pres-
sures, the system will automatically update
and the “Tire Pressure Monitoring Telltale
Light” will turn off.NOTE:
When filling warm tires, the tire pressure may
need to be increased up to an additional 4 psi
(30 kPa) above the recommended cold plac-
ard pressure in order to turn the Tire Pressure
Monitoring Telltale Light off. The vehicle may
need to be driven for up to 10 minutes above
15 mph (24 km/h) in order for the TPMS to
receive this information.
Service TPMS Warning
When a system fault is detected, the “Tire
Pressure Monitoring Telltale Light” will flash
on and off for 75 seconds and then remain on
solid. The system fault will also sound a
chime. If the ignition is cycled, this sequence
will repeat, providing the system fault still
exists. The “Tire Pressure Monitoring Telltale
Light” will turn off when the fault condition
no longer exists. A system fault can occur due
to any of the following:
• Jamming due to electronic devices or driv-
ing next to facilities emitting the same
radio frequencies as the TPMS sensors.
• Installing some form of aftermarket window
tinting that affects radio wave signals.
93

• Lots of snow or ice around the wheels or
wheel housings.
• Using tire chains on the vehicle.
• Using wheels/tires not equipped with
TPMS sensors.
Vehicles With Compact Spare or non-Matching
Full Size Spare
1. The compact spare tire or non-matching
full size spare tire does not have a tire
pressure monitoring sensor. Therefore,
the TPMS will not monitor the pressure in
the spare tire.
2. If you install the compact or non-
matching full size spare tire in place of a
road tire that has a pressure below the
low-pressure warning limit, a chime will
sound and the “TPMS Telltale Light” and
“LOW TIRE PRESSURE” message will
turn on upon the next ignition cycle.
3. After driving the vehicle for up to 10 min-
utes above 15 mph (24 km/h), the “TPMS
Telltale Light” will flash on and off for
75 seconds and then remain on solid.4. For each subsequent ignition cycle, a
chime will sound and the “TPMS Telltale
Light” will flash on and off for 75 seconds
and then remain on solid.
5. Once you repair or replace the original
road tire and reinstall it on the vehicle in
place of the compact spare, the TPMS will
update automatically and the “TPMS Tell-
tale Light” will turn off, as long as no tire
pressure is below the low-pressure warn-
ing limit in any of the four active road
tires. The vehicle may need to be driven
for up to 10 minutes above 15 mph
(24 km/h) in order for the TPMS to receive
this information.

Low" message and a graphic showing the
pressure values of each tire with the low tire
pressure values highlighted or in a different
color.
Should this occur, you should stop as soon as
possible and inflate the tires with low pres-
sure (those highlighted or in a different color
in the instrument cluster display graphic) to
the vehicle’s recommended cold placard
pressure value. Once the system receives the
updated tire pressures, the system will auto-
matically update, the pressure values in the
graphic display in the instrument cluster will
stop being highlighted or return to their origi-
nal color, and the “Tire Pressure Monitoring
Telltale Light” will turn off.
NOTE:
When filling warm tires, the tire pressure may
need to be increased up to an additional 4 psi
(30 kPa) above the recommended cold plac-
ard pressure in order to turn the Tire Pressure
Monitoring Telltale Light off. The vehicle may
need to be driven for up to 10 minutes above
15 mph (24 km/h) in order for the TPMS to
receive this information.SERVICE TPMS Warning
When a system fault is detected, the “Tire
Pressure Monitoring Telltale Light” will flash
on and off for 75 seconds and then remain on
solid. The system fault will also sound a
chime. In addition, the instrument cluster
will display a "SERVICE TPM SYSTEM" mes-
sage for a minimum of five seconds and then
display dashes (- -) in place of the pressure
value to indicate which sensor is not being
received.
If the ignition key is cycled, this sequence
will repeat, providing the system fault still
exists. If the system fault no longer exists, the
“Tire Pressure Monitoring Telltale Light” will
no longer flash, and the “SERVICE TPM SYS-
TEM” message will no longer display, and a
pressure value will display in place of the
dashes. A system fault can occur due to any
of the following:
• Jamming due to electronic devices or driv-
ing next to facilities emitting the same
radio frequencies as the TPMS sensors.
• Installing some form of aftermarket window
tinting that affects radio wave signals.• Lots of snow or ice around the wheels or
wheel housings.
• Using tire chains on the vehicle.
• Using wheels/tires not equipped with TPMS
sensors.
Vehicles With Compact Spare or Non-Matching
Full Size Spare
1. The compact spare tire or non-matching
full size does not have a tire pressure
monitoring sensor. Therefore, the TPMS
will not monitor the pressure in the com-
pact spare tire.
2. If you install the compact or non-
matching full size spare tire in place of a
road tire that has a pressure below the
low-pressure warning limit, upon the next
ignition key cycle, the “TPMS Telltale
Light” will remain on and a chime will
sound. In addition, the graphic in the
instrument cluster will still display a dif-
ferent color or highlighted pressure value.
95

3. After driving the vehicle for up to 10 min-
utes above 15 mph (24 km/h), the “TPMS
Telltale Light” will flash on and off for
75 seconds and then remain on solid. In
addition, the instrument cluster will dis-
play a “SERVICE TPM SYSTEM” message
for five seconds and then display dashes
(- -) in place of the pressure value.
4. For each subsequent ignition key cycle, a
chime will sound, the “TPMS Telltale
Light” will flash on and off for 75 seconds
and then remain on solid, and the instru-
ment cluster will display a “SERVICE
TPM SYSTEM” message for five seconds
and then display dashes (- -) in place of
the pressure value.
5. Once you repair or replace the original
road tire and reinstall it on the vehicle in
place of the compact spare, the TPMS will
update automatically. In addition, the
“TPMS Telltale Light” will turn off and the
graphic in the instrument cluster will dis-play a new pressure value instead of
dashes (- -), as long as no tire pressure is
below the low-pressure warning limit in
any of the four active road tires. The
vehicle may need to be driven for up to
10 minutes above 15 mph (24 km/h) in
order for the TPMS to receive this
information.
TPMS Deactivation — If Equipped
The TPMS can be deactivated if replacing all
four wheel and tire assemblies (road tires)
with wheel and tire assemblies that do not
have TPMS Sensors, such as when installing
winter wheel and tire assemblies on your
vehicle.
To deactivate the TPMS, first replace all four
wheel and tire assemblies (road tires) with
tires not equipped with Tire Pressure Moni-
toring (TPM) Sensors. Then, drive the vehicle
for 10 minutes above 15 mph (24 km/h). The
TPMS will chime, the "TPM Telltale Light"
will flash on and off for 75 seconds and thenremain on. The instrument cluster will dis-
play the “SERVICE TPM SYSTEM” message
and then display dashes (--) in place of the
pressure values.
Beginning with the next ignition cycle, the
TPMS will no longer chime or display the
“SERVICE TPM SYSTEM” message in the
instrument cluster but dashes (--) will remain
in place of the pressure values.
To reactivate the TPMS, replace all four
wheel and tire assemblies (road tires) with
tires equipped with TPM sensors. Then, drive
the vehicle for up to 10 minutes above
15 mph (24 km/h). The TPMS will chime, the
"TPM Telltale Light" will flash on and off for
75 seconds and then turn off. The instrument
cluster will display the “SERVICE TPM SYS-
TEM” message and then display pressure
values in place of the dashes. On the next
ignition cycle the "SERVICE TPM SYSTEM"
message will no longer be displayed as long
as no system fault exists.

Air Bag Warning Light
The ORC monitors the readiness of the
electronic parts of the air bag system when-
ever the ignition switch is in the START or
ON/RUN position. If the ignition switch is in
the OFF position or in the ACC position, the
air bag system is not on and the air bags will
not inflate.
The ORC contains a backup power supply
system that may deploy the air bag system
even if the battery loses power or it becomes
disconnected prior to deployment.
The ORC turns on the Air Bag Warning Light
in the instrument panel for approximately
four to eight seconds for a self-check when
the ignition switch is first in the ON/RUN
position. After the self-check, the Air Bag
Warning Light will turn off. If the ORC detectsa malfunction in any part of the system, it
turns on the Air Bag Warning Light, either
momentarily or continuously. A single chime
will sound to alert you if the light comes on
again after initial startup.
The ORC also includes diagnostics that will
illuminate the instrument panel Air Bag
Warning Light if a malfunction is detected
that could affect the air bag system. The
diagnostics also record the nature of the
malfunction. While the air bag system is
designed to be maintenance free, if any of
the following occurs, have an authorized
dealer service the air bag system immedi-
ately.
• The Air Bag Warning Light does not come
on during the four to eight seconds when
the ignition switch is first in the ON/RUN
position.
• The Air Bag Warning Light remains on after
the four to eight-second interval.
• The Air Bag Warning Light comes on inter-
mittently or remains on while driving.NOTE:
If the speedometer, tachometer, or any en-
gine related gauges are not working, the Oc-
cupant Restraint Controller (ORC) may also
be disabled. In this condition the air bags
may not be ready to inflate for your protec-
tion. Have an authorized dealer service the
air bag system immediately.WARNING!
Ignoring the Air Bag Warning Light in your
instrument panel could mean you won’t
have the air bag system to protect you in a
collision. If the light does not come on as a
bulb check when the ignition is first
turned on, stays on after you start the
vehicle, or if it comes on as you drive, have
an authorized dealer service the air bag
system immediately.
