2019 JEEP COMPASS light

• HSA will work in REVERSE gear and all
forward gears. The system will not activate
if the transmission is in PARK or NEU-
TRAL. For vehicles equipped with a manual
transmission, if the clutch is pressed, HSA
will remain active.
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 op-
eration 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 warn-
ings can result in a collision or serious
personal injury.
Towing With HSA
HSA will also provide assistance to mitigate
roll back while towing a trailer.
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 roll-
ing down an incline while resuming ac-
celeration, manually activate the trailer
brake or apply more vehicle brake pres-
sure 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 re-
sult in a collision or serious personal
injury.
Disabling And Enabling HSA
This feature can be turned on or turned off. To
change the current setting, proceed as fol-
lows:
• If disabling HSA using Uconnect Settings,
refer to “Uconnect Settings” in “Multime-
dia” for further information.
Rain Brake Support (RBS)
Rain Brake Support may improve braking
performance in wet conditions. It will periodi-
cally apply a small amount of brake pressure
to remove any water buildup on the front
brake rotors. It functions when the wind-
shield wipers are in LO or HI speed. When
Rain Brake Support is active, there is no
notification to the driver and no driver inter-
action is required.
Ready Alert Braking (RAB)
Ready Alert Braking may reduce the time
required to reach full braking during emer-
gency braking situations. It anticipates when
an emergency braking situation may occur by
87

monitoring how fast the throttle is released by
the driver. The EBC will prepare the brake
system for a panic stop.
Trailer Sway Control (TSC)
TSC uses sensors in the vehicle to recognize
an excessively swaying trailer and will take
the appropriate actions to attempt to stop the
sway. TSC will become active automatically
once an excessively swaying trailer is recog-
nized.
NOTE:
TSC cannot stop all trailers from swaying.
Always use caution when towing a trailer and
follow the trailer tongue weight recommenda-
tions. Refer to “Trailer Towing” in “Starting
And Operating” for further information.
When TSC is functioning, the “ESC
Activation/Malfunction Indicator Light” will
flash, the engine power may be reduced and
you may feel the brakes being applied to
individual wheels to attempt to stop the
trailer from swaying. TSC is disabled when
the ESC system is in the “Partial Off” or “Full
Off” modes.
WARNING!
If TSC activates while driving, slow the
vehicle down, stop at the nearest safe
location, and adjust the trailer load to
eliminate trailer sway.
AUXILIARY DRIVING
SYSTEMS
Blind Spot Monitoring (BSM) —
If Equipped
The Blind Spot Monitoring (BSM) system
uses two radar-based sensors, located inside
the rear bumper fascia, to detect highway
licensable vehicles (automobiles, trucks, mo-
torcycles, etc.) that enter the blind spot
zones from the rear/front/side of the vehicle.When the vehicle is started, the BSM warning
light will momentarily illuminate in both out-
side rear view mirrors to let the driver know
that the system is operational. The BSM
system sensors operate when the vehicle is in
any forward gear or REVERSE and enters
stand-by mode when the vehicle is in PARK.
The BSM detection zone covers approxi-
mately one lane width on both sides of the
vehicle 12 ft (3.8 m). The zone length starts
at the outside mirror and extends approxi-
mately 10 ft (3 m) beyond the rear bumper of
the vehicle. The BSM system monitors the
detection zones on both sides of the vehicle
Rear Detection Zones
SAFETY
88

when the vehicle speed reaches approxi-
mately 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 detection zone DOES NOT
change if your vehicle is towing a trailer.
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 equip-
ment) extends beyond the side of your ve-
hicle, 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 miss-detection. Refer to
“Uconnect Settings” in “Multimedia” in
the Owner’s Manual for further information.• The Blind Spot Monitoring (BSM) system
may experience drop outs (blinking on and
off) of the side mirror Warning Indicator
lamps when a motorcycle or any small ob-
ject remains at the side of the vehicle for
extended periods of time (more than a
couple of seconds).
The area on the rear fascia where the radar
sensors are located must remain free of snow,
ice, and dirt/road contamination so that the
BSM system can function properly. Do not
block the area of the rear fascia where the
radar sensors are located with foreign objects
(bumper stickers, bicycle racks, etc.)
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 pres-
ent 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 audio alerts will be issued. In addition to
the audible alert the radio (if on) will also be
muted.The BSM system monitors the detection zone
from three different entry points (side, rear,
front) while driving to see if an alert is neces-
sary. The BSM system will issue an alert
during these types of zone entries.
Entering From The Side
Vehicles that move into your adjacent lanes
from either side of the vehicle.
Entering From The Rear
Vehicles that come up from behind your ve-
hicle on either side and enter the rear detec-
tion zone with a relative speed of less than
30 mph (48 km/h).
BSM Warning Light
89

Overtaking Traffic
If you pass another vehicle slowly with a
relative speed less than 10 mph (16 km/h)
and the vehicle remains in the blind spot for
approximately 1.5 seconds, the warning light
will be illuminated. If the difference in speed
between the two vehicles is greater than
10 mph (16 km/h), the warning light will not
illuminate.
The BSM system is designed not to issue an
alert on stationary objects such as guardrails,
posts, walls, foliage, berms, etc. However,
occasionally the system may alert on such
objects. This is normal operation and your
vehicle does not require service.
The BSM system will not alert you of objects
that are traveling in the opposite direction of
the vehicle in adjacent lanes.
NOTE:
The BSM system may experience drop outs
(blinking on and off) in the side mirror LED
icons while a motorcycle, or any small target,
remains at the vehicle’s B-pillar for an ex-
tended period of time (longer than a couple of
seconds).WARNING!
The Blind Spot Monitoring system is only
an aid to help detect objects in the blind
spot zones. The BSM system is not de-
signed to detect pedestrians, bicyclists, or
animals. Even if your vehicle is equipped
with the BSM system, always check your
vehicle’s mirrors, glance over your shoul-
der, and use your turn signal before chang-
ing lanes. Failure to do so can result in
serious injury or death.
Rear Cross Path (RCP)
The Rear Cross Path (RCP) feature is in-
tended to aid the driver when backing out of
parking spaces where their vision of oncom-
ing vehicles may be blocked. Proceed slowly
and cautiously out of the parking space until
the rear end of the vehicle is exposed. The
RCP system will then have a clear view of the
cross traffic and if an oncoming vehicle is
detected, alert the driver.
RCP monitors the rear detection zones on
both sides of the vehicle, for objects that are
moving toward the side of the vehicle with a
minimum speed of approximately 3 mph(5 km/h), to objects moving a maximum of
approximately 20 mph (32 km/h), such as in
parking lot situations.
NOTE:
In a parking lot situation, oncoming vehicles
can be obscured by vehicles parked on either
side. If the sensors are blocked by other
structures or vehicles, the system will not be
able to alert the driver.
When RCP is on and the vehicle is in RE-
VERSE, the driver is alerted using both the
visual and audible alarms, including reduc-
ing the radio volume.
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, the
system 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. Whenever
an 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 Mitigation 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.

internal system fault. Although the vehicle is
still drivable under normal conditions, have
the system checked by an authorized dealer.
Tire Pressure Monitor System (TPMS)
The Tire Pressure Monitor System (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 pres-
sure molded into the tire sidewall. Refer to
“Tires” in “Servicing And Maintenance” for
information on how to properly inflate the
vehicle’s tires. The tire pressure will also
increase as the vehicle is driven. This is
normal and there should be no adjustment for
this increased pressure.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 natu-
ral 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 pres-
sure.
NOTE:
Once the low tire pressure warning (TPMS
Warning Light) illuminates, you must in-
crease the tire pressure to the recommended
cold placard pressure in order for the TPMS
Warning Light to turn off.
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 plac-
ard pressure in order to turn the TPMS Warn-
ing Light off.
The system will automatically update and the
TPMS Warning Light will turn off once the
system receives the updated tire pressures.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.
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 “TPMS Warning
Light.” Driving the vehicle may cause the tire
pressure to rise to approximately 28 psi
(193 kPa), but the TPMS Warning Light will
still be on. In this situation, the TPMS Warn-
ing Light will turn off only after the tires are
inflated to the vehicle’s recommended cold
placard pressure value.
CAUTION!
• The TPMS has been optimized for the
original equipment tires and wheels.
TPMS pressures and warning have been

CAUTION!
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
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 TPMS Warning
Light.
• Seasonal temperature changes will affect
tire pressure, and the TPMS will monitor
the actual tire pressure in the tire.
• The system only warns the tire pressure is
low: it is not able to inflate them.
Premium 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
• Various Tire Pressure Monitoring System
messages, which will display in the instru-
ment cluster display.
• Tire Pressure Monitoring System Warning
Light

Tire Pressure Monitoring Low Pressure
Warnings
The Tire Pressure Monitoring System
Warning Light will illuminate in the
instrument cluster and a chime will
sound when tire pressure is low in one or
more of the four active road tires. In addition,
the instrument cluster will display a "Tire
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
System Warning Light will turn off.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 plac-
ard pressure in order to turn the Tire Pressure
Monitoring System Warning 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 System Warning 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 SYS-
TEM" message 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 System Warning
Light will no longer flash, and the “SERVICE
TPM SYSTEM” message will no longer dis-play, 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 or non-matching full size spare tire.
