2023 JEEP COMPASS ESP

192SAFETY
HDC has three states:

1. Off (feature is not enabled and will not activate).

2. Enabled (feature is enabled and ready but activation conditions are not met, or driver is
actively overriding with brake or throttle
application).
3. Active (feature is enabled and actively controlling vehicle speed).
Enabling HDC
HDC is enabled by pushing the HDC switch, located
in front of the gear selector. The following
conditions must also be met to enable HDC:
The driveline is in 4WD Low.
The vehicle speed is below 20 mph (32 km/h).
The Electric Park Brake (EPB) is released.
The driver’s door is closed.
Activating HDC
Once HDC is enabled, it will activate automatically
if driven down a grade of sufficient magnitude
(greater than approximately 8%). The set speed for
HDC is selectable by the driver and can be
adjusted within the thresholds by using throttle or
brake application. Driver Override:
The driver may override HDC activation speed with
throttle or brake application at any time.
Deactivating HDC
HDC will be deactivated but remain available if any
of the following conditions occur:
Driver overrides HDC set speed with a speed
exceeding 20 mph (32 km/h) but remains
below 25 mph (40 km/h).
Vehicle is on a downhill grade of insufficient
magnitude (less than approximately 8%), is on
level ground, or is on an uphill grade.
Vehicle is shifted to PARK.
Disabling HDC
HDC will be deactivated and disabled if any of the
following conditions occur:
The driver pushes the HDC switch.
The driveline is shifted out of 4WD Low.
The driver’s door opens.
The vehicle is driven greater than 25 mph
(40 km/h) (HDC exits immediately.) Feedback To The Driver:
The instrument cluster has an HDC icon and the
HDC switch has an LED, which offers feedback to
the driver about the state HDC is in.
The cluster icon and switch lamp will illuminate
and remain solid when HDC is enabled or acti
-
vated. This is the normal operating condition for
HDC.
The switch lamp will flash for several seconds
then extinguish when the driver pushes the HDC
switch when enable conditions have not been
met.
The HDC switch is located within the Selec-Terrain
knob in the upper right position.
WARNING!
HDC is only intended to assist the driver in
controlling vehicle speed when descending hills.
The driver must remain attentive to the driving
conditions and is responsible for maintaining a
safe vehicle speed.

SAFETY193
Hill Start Assist (HSA)
HSA is designed to mitigate roll back from a
complete stop while on an incline. If the driver
releases the brake while stopped on an incline,
HSA will continue to hold the brake pressure for a
short period. If the driver does not apply the
throttle before this time expires, the system will
release brake pressure and the vehicle will roll
down the hill as normal.
The following conditions must be met in order for
HSA to activate:
The feature must be enabled.
The vehicle must be stopped.
The parking brake must be off.
The driver’s door must be closed.
The vehicle must be on a sufficient grade.
The gear selection must match vehicle uphill
direction (i.e., vehicle facing uphill is in forward
gear; vehicle backing uphill is in REVERSE gear).
HSA will work in REVERSE gear and all forward
gears. The system will not activate if the trans -
mission is in PARK or NEUTRAL.
Disabling And Enabling HSA
This feature can be turned on or turned off. To
change the current setting, proceed as follows:
If disabling HSA using Uconnect settings see
Ú page 77.
Towing With HSA
Hill Start Assist (HSA) will also provide assistance
to mitigate roll back while towing a trailer.
Rain Brake Support (RBS)
RBS may improve braking performance in wet
conditions. It will periodically apply a small amount
of brake pressure to remove any water buildup on
the front brake rotors. It functions when the
windshield wipers are in LO or HI speed. When Rain
Brake Support is active, there is no notification to
the driver and no driver interaction is required.
WARNING!
There may be situations where the Hill Start
Assist (HSA) will not activate and slight rolling
may occur, such as on minor hills or with a
loaded vehicle, or while pulling a trailer. HSA is
not a substitute for active driving involvement.
It is always the driver’s responsibility to be
attentive to distance to other vehicles, people,
and objects, and most importantly brake
operation to ensure safe operation of the vehicle
under all road conditions. Your complete
attention is always required while driving to
maintain safe control of your vehicle. Failure to
follow these warnings can result in a collision or
serious personal injury.
WARNING!
If you use a trailer brake controller with your
trailer, the trailer brakes may be activated and
deactivated with the brake switch. If so, there
may not be enough brake pressure to hold
both the vehicle and the trailer on a hill when
the brake pedal is released. In order to avoid
rolling down an incline while resuming accel -
eration, manually activate the trailer brake or
apply more vehicle brake pressure prior to
releasing the brake pedal.
HSA is not a parking brake. Always apply the
parking brake fully when exiting your vehicle.
Also, be certain to place the transmission
in PARK.
Failure to follow these warnings can result in a
collision or serious personal injury.

SAFETY195
The BSM detection zone covers approximately
one lane width, 12 ft (3.8 m), on both sides of the
vehicle. The zone length starts at the outside
mirror and extends approximately 10 ft (3 m)
beyond the rear fascia/bumper of the vehicle. The
BSM system monitors the detection zones on both
sides of the vehicle when the vehicle speed
reaches approximately 6 mph (10 km/h) or higher
and will alert the driver of vehicles in these areas.
NOTE:
The BSM system DOES NOT alert the driver
about rapidly approaching vehicles that are
outside the detection zones.
The BSM system will automatically disable when
a trailer is detected. If the attached trailer is not
detected, the system detection zone DOES NOT
change. Therefore, visually verify the adjacent
lane is clear for both your vehicle and trailer
before making a lane change. If the trailer or
other object (i.e., bicycle, sports equipment)
extends beyond the side of your vehicle, this
may result in the BSM warning light remaining
illuminated the entire time the vehicle is in a
forward gear. It may be necessary to deactivate
the BSM system manually to avoid misdetection
Ú page 165.
The BSM system can become blocked if snow, ice,
mud, or other road contaminations accumulate on
the rear fascia/bumper where the radar sensors
are located. The system may also detect blockage if the vehicle is operated in areas with extremely
low radar returns such as a desert or parallel to a
large elevation drop. If blockage is detected, a
“Blind Spot Temporarily Unavailable, Sensor
Blocked” message will display in the cluster, both
mirror lights will illuminate, and BSM and RCP
alerts will not occur. This is normal operation. The
system will automatically recover and resume
function when the condition clears or when an
ignition cycle occurs. To minimize system
blockage, do not block the area of the rear fascia/
bumper where the radar sensors are located with
foreign objects (bumper stickers, bicycle racks,
etc.) and keep it clear of road contaminations.

Radar Sensor Location (Driver Side Shown)

The BSM system will provide a visual alert in the
appropriate side view mirror based on a detected
object when enabled. 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 chimes are enabled. In addition
to the audible alert the radio (if on) will also be
muted during the chime event Ú
page 198.

Warning Light Location

As part of the Active Lane Management system, if
the vehicle begins to drift into an adjacent lane
that has an active LED indication, the LED will flash
if steering torque is provided to guide the vehicle
back to the center of the lane Ú page 145.
The BSM system monitors the detection zone from
three different entry points (side, rear, front) while
driving to see if an alert is necessary. The BSM
system will issue an alert during these types of
zone entries.

198SAFETY
Blind Spot Modes
Blind Spot Alert has three selectable modes of
operation that are available in the Uconnect
system.
Blind Spot Alert Lights Only (Default Setting)
When operating in Lights Only mode, the BSM
system will provide a visual alert in the appropriate
side view mirror based on a detected object.
However, when the system is operating in Rear
Cross Path (RCP) mode, the system will respond
with both visual and audible alerts when a
detected object is present. Whenever an audible
alert is requested, the radio is muted for the
duration of the chime.
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. Whenever 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. When the system is in RCP, the system shall
respond with both visual and audible alerts when a
detected object is present. Whenever an audible
alert is requested, the radio volume 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 operating
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 mirrors will be illuminated.
The warning indicators will remain illuminated until
blockage clearing conditions are met. First clear
the fascia/bumper area around the sensors of the
blockage. After removing the blockage, reset the
system by cycling the ignition from ON to OFF and
then back ON.
FORWARD COLLISION WARNING (FCW)
W
ITH MITIGATION — IF EQUIPPED
FCW with Mitigation provides the driver with
audible 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 forward
looking sensors as well as the Electronic Brake
Controller (EBC), to calculate the probability of a
forward collision. When the system 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 to help slow the
vehicle and mitigate the potential forward collision.
If the driver reacts to the warnings by braking and
the system determines that the driver intends to
avoid the collision by braking but has not applied
sufficient brake force, the system will compensate
and provide additional brake force as required.

22_MP_OM_EN_USC_t.book Page 198

SAFETY199
If a Forward Collision Warning with Mitigation event
begins at a speed below 39 mph (62 km/h), the
system may provide the maximum braking
possible to mitigate the potential forward collision.
If the Forward Collision Warning with Mitigation
event stops the vehicle completely, the system will
hold the vehicle at standstill for two seconds and
then release the brakes.

FCW Message

When the system determines a collision with the
vehicle in front of you is no longer probable, the
warning message will be deactivated Úpage 328.
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 guardrails 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 prevent unnec -
essary warnings to the surroundings.
FCW Settings
The Forward Collision menu setting is located in
the Uconnect Settings Ú page 165.
NOTE:The default status of FCW is “Full On,” this allows
the system to provide warning and autonomous
braking in the event of a potential frontal collision.
Changing the FCW status to “Only Warning”
prevents the system from providing autonomous
braking, or additional brake support if the driver is
not braking adequately in the event of a potential
frontal collision.
Changing the FCW status to “Off” deactivates the
system, so no warning or autonomous braking will
be available in case of a possible collision.
NOTE:The FCW system state is kept in memory from one
ignition cycle to the next. If the system is turned off,
it will remain off when the vehicle is restarted.
Changing FCW Sensitivity And Operating
Status
The FCW Sensitivity and Operation settings are
programmable through the Uconnect system
Úpage 165.
The default status of FCW is the “Medium” setting
and the FCW is in the “Full On” setting. This allows
the system to warn the driver of a possible collision
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 vehicle via braking and steering.
Failure to follow this warning could lead to
serious injury or death.

SAFETY201
Turning PEB On Or Off
NOTE:The default status of PEB is “On.” This allows the
system to warn you of a possible frontal collision
with the pedestrian.
The PEB button is located in the Uconnect display
in the Controls settings Ú page 165.
To turn the PEB system off, push the Pedestrian
Emergency Braking OFF button.
To turn the PEB system back on, push the Warning
Active Braking button.
Changing the PEB status to “Off” deactivates the
system, so no warning or active braking will be
available in case of a possible frontal collision with
the pedestrian/cyclist.
NOTE:The PEB system will retain the last setting selected
by the driver after ignition shut down. The system
will not reset to the default setting when the
vehicle is restarted.
TIRE PRESSURE MONITORING SYSTEM
(TPMS)
The TPMS will warn the driver of a low tire pressure
based on the vehicle recommended cold placard
pressure.
The tire pressure will vary with temperature by
approximately 1 psi (7 kPa) for every 12°F (6.5°C).
This means that when the outside temperature
decreases, the tire pressure will decrease. Tire
pressure should always be set based on cold
inflation tire pressure. This is defined as the tire
pressure after the vehicle has not been driven for
at least three hours, or driven less than 1 mile
(1.6 km) after a three hour period. The cold tire
inflation pressure must not exceed the maximum
inflation pressure molded into the tire sidewall.
The tire pressure will also increase as the vehicle
is driven. This is normal and there should be no
adjustment for this increased pressure.
For more information on how to properly inflate the
vehicle’s tires, see Ú page 298.
The TPMS will warn the driver of a low tire pressure
if the tire pressure falls below the low-pressure
warning limit for any reason, including low temperature effects and natural pressure loss
through the tire. The TPMS will continue to warn
the driver of low tire pressure as long as the
condition exists, and will not turn off until the tire
pressure is at or above the recommended cold
placard pressure.
NOTE:
Once the low tire pressure warning (Tire Pressure
Monitoring System Warning Light) illuminates, you
must increase the tire pressure to the recommended
cold placard pressure in order for the Tire Pressure
Monitoring System Warning Light to turn off.

The system will automatically update and the Tire
Pressure Monitoring System Warning Light will turn
off once the system receives the updated tire
pressures. The vehicle may need to be driven for
up to 20 minutes above 15 mph (24 km/h) in
order for the TPMS to receive this information.
For example, your vehicle may have a
recommended 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 approximately 24 psi (165 kPa).
This tire pressure is low enough to turn on the Tire
Pressure Monitoring System Warning Light. Driving
the vehicle may cause the tire pressure to rise to
approximately 28 psi (193 kPa), but the Tire
Pressure Monitoring System Warning Light will still
WARNING!
Pedestrian Emergency Braking (PEB) is not
intended to avoid a collision on its own, nor can
PEB detect every type of potential collision with
a pedestrian. The driver has the responsibility to
avoid a collision by controlling the vehicle via
braking and steering. Failure to follow this
warning could lead to serious injury or death.

be on. In this situation, the Tire Pressure
Monitoring System Warning Light will turn off only
after the tires are inflated to the vehicle’s
recommended cold placard pressure value
Ú
page 328.
NOTE:When filling warm tires, the tire pressure may need
to be increased up to an additional 4 psi (28 kPa)
above the recommended cold placard pressure in
order to turn the Tire Pressure Monitoring System
Warning Light off.
NOTE:
The TPMS is not intended to replace normal tire
care and maintenance, or to provide 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 effi -
ciency 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 responsibility
to maintain correct tire pressure using an accu -
rate tire pressure gauge, even if underinflation
has not reached the level to trigger illumination
of the Tire Pressure Monitoring System Warning
Light.
Seasonal temperature changes will affect tire
pressure, and the TPMS will monitor the actual
tire pressure in the tire.
Premium System
The Tire Pressure Monitoring 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 components:
Receiver module
Four Tire Pressure Monitoring System sensors
Various Tire Pressure Monitoring System
messages, which will display in the instrument
cluster display
Tire Pressure Monitoring System Warning Light
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 operation or sensor damage may
result when using replacement equipment
that is not of the same size, type, and/or style.
The TPMS sensor is not designed for use on
aftermarket wheels and may contribute to a
poor overall system performance or sensor
damage. Customers are encouraged to use
OEM wheels to ensure proper TPMS feature
operation.
Using aftermarket tire sealants may cause the
Tire Pressure Monitoring System (TPMS)
sensor to become inoperable. After using an
aftermarket tire sealant it is recommended
that you take your vehicle to an 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 from entering the
valve stem, which could damage the TPMS
sensor.
CAUTION!

SAFETY221
The SABICs may help reduce the risk of partial or
complete ejection of vehicle occupants through
side windows in certain side impact events. Side Impacts
The Side Air Bags are designed to activate in
certain side impacts. The Occupant Restraint
Controller (ORC) determines whether the
deployment of the Side Air Bags in a particular
impact event is appropriate, based on the severity
and type of collision. The side impact sensors aid
the ORC in determining the appropriate response
to impact events. The system is calibrated to
deploy the Side Air Bags on the impact side of the
vehicle during impacts that require Side Air Bag
occupant protection. In side impacts, the Side Air
Bags deploy independently; a left side impact
deploys the left Side Air Bags only and a right-side
impact deploys the right Side Air Bags only. Vehicle
damage by itself is not a good indicator of whether
or not Side Air Bags should have deployed.
The Side Air Bags will not deploy in all side
collisions, including some collisions at certain
angles, or some side collisions that do not impact
the area of the passenger compartment. The Side
Air Bags may deploy during angled or offset frontal
collisions where the front air bags deploy.Side Air Bags are a supplement to the seat belt
restraint system. Side Air Bags deploy in less time
than it takes to blink your eyes.
WARNING!
Do not mount equipment, or stack luggage or
other cargo up high enough to block the
deployment of the SABICs. The trim covering
above the side windows where the SABIC and
its deployment path are located should
remain free from any obstructions.
In order for the SABICs to work as intended, do
not install any accessory items in your vehicle
which could alter the roof. Do not add an after
-
market sunroof to your vehicle. Do not add
roof racks that require permanent attach -
ments (bolts or screws) for installation on the
vehicle roof. Do not drill into the roof of the
vehicle for any reason.
WARNING!
Occupants, including children, who are up
against or very close to Side Air Bags can be
seriously injured or killed. Occupants,
including children, should never lean on or
sleep against the door, side windows, or area
where the side air bags inflate, even if they are
in an infant or child restraint.
Seat belts (and child restraints where appro -
priate) are necessary for your protection in all
collisions. They also help keep you in position,
away from an inflating Side Air Bag. To get the
best protection from the Side Air Bags, occu -
pants must wear their seat belts properly and
sit upright with their backs against the seats.
Children must be properly restrained in a child
restraint or booster seat that is appropriate for
the size of the child.
