2022 CHRYSLER PACIFICA warning light

SAFETY227
ESC Activation/Malfunction Indicator Light
And ESC OFF Indicator Light
The ESC Activation/Malfunction Indicator
Light in the instrument cluster will come
on when the ignition is placed in the ON/
RUN mode. It should go out with the
engine running. If the ESC Activation/Malfunction
Indicator Light comes on continuously with the
engine running, a malfunction has been detected
in the ESC system. If this light remains on after
several ignition cycles, and the vehicle has been
driven several miles (kilometers) at speeds greater
than 30 mph (48 km/h), see an authorized dealer
as soon as possible to have the problem
diagnosed and corrected. The ESC Activation/Malfunction Indicator Light
starts to flash as soon as the tires lose traction and
the ESC system becomes active. The ESC
Activation/Malfunction Indicator Light also flashes
when TCS is active. If the ESC Activation/
Malfunction Indicator Light begins to flash during
acceleration, ease up on the accelerator and apply
as little throttle as possible. Be sure to adapt your
speed and driving to the prevailing road conditions.
The ESC OFF Indicator Light indicates
that the Electronic Stability Control (ESC)
is in a reduced mode.
NOTE:
The ESC Activation/Malfunction Indicator Light
and the ESC OFF Indicator Light come on
momentarily each time the ignition is placed in
the ON/RUN position.
Each time the ignition is placed in the ON/RUN
position, the ESC system will be on even if it was
turned off previously.
The ESC system will make buzzing or clicking
sounds when it is active. This is normal; the
sounds will stop when ESC becomes inactive
following the maneuver that caused the ESC
activation.
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 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
(R) gear).
HSA will work in REVERSE gear and all forward
gears. The system will not activate if the trans -
mission is in PARK (P) or NEUTRAL (N).
WARNING!
When in “Partial Off” mode, the TCS function -
ality of ESC (except for the limited slip feature
described in the TCS section) has been
disabled and the ESC OFF Indicator Light will
be illuminated. When in “Partial Off” mode,
the engine power reduction feature of TCS is
disabled, and the enhanced vehicle stability
offered by the ESC system is reduced.
Trailer Sway Control (TSC) is disabled when
the ESC system is in the “Partial Off” mode.

Disabling And Enabling HSA
This feature can be turned on or turned off. To
change the current setting, proceed as follows:
Úpage 188.
Towing With HSA
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 RBS
is active, there is no notification to the driver and
no driver interaction is required.
Ready Alert Braking (RAB)
RAB may reduce the time required to reach full
braking during emergency braking situations. It
anticipates when an emergency braking situation
may occur by monitoring how fast the throttle is
released by the driver. The Electronic Brake
Control (EBC) system will prepare the brake system
for a panic stop.
Rear Seat Reminder Alert (RSRA)
RSRA will consider the presence of an object in the
rear seat when a rear entry/exit door is opened at
the beginning of each key cycle. To activate, the
rear door must be open for more than one second
and the vehicle must be placed in the ON/RUN
position within 10 minutes. When the potential
presence of an object is determined and/or
otherwise inferred, a message will appear in the
instrument cluster display reminding driver to
check the rear seat(s) immediately after key off
accompanied by an alert upon exiting the vehicle.
Traction Control System (TCS)
The TCS monitors the amount of wheel spin of
each of the driven wheels. If wheel spin is
detected, the TCS may apply brake pressure to the
spinning wheel(s) and/or reduce vehicle power to
provide enhanced acceleration and stability. A
feature of the TCS, Brake Limited Differential (BLD)
functions similarly to a limited slip differential and
controls the wheel spin across a driven axle.
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.

22_RUP_OM_EN_USC_t.book Page 228

SAFETY229
If one wheel on a driven axle is spinning faster than
the other, the system will apply the brake of the
spinning wheel. This will allow more vehicle torque
to be applied to the wheel that is not spinning. BLD
may remain enabled even if TCS and the Electronic
Stability Control (ESC) are in reduced modes.
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.
Note that TSC cannot stop all trailers from swaying.
Always use caution when towing a trailer and follow
the trailer tongue weight recommendations
Ú page 174.
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” mode.
AUXILIARY DRIVING SYSTEMS
BLIND SPOT MONITORING (BS M) —
I
F EQUIPPED
The BSM system uses two radar sensors, located
inside the rear fascia/bumper, to detect highway
licensable vehicles (automobiles, trucks,
motorcycles, etc.) that enter the blind spot zones
from the rear/front/side of the vehicle.

Rear Detection Zones

When the vehicle is started, the BSM Warning Light
will momentarily illuminate in both outside
rearview mirrors to let the driver know that the
system is operational. The BSM system sensors
operate when the vehicle is in any forward gear
and enters standby mode when the vehicle is in
PARK (P). The BSM detection zone covers approximately one
lane width on both sides of the vehicle 12 ft
(3.7 m). The zone length starts at the outside
rearview 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 detection zone DOES NOT
change if your vehicle is towing a trailer. There
-
fore, 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 false
detections. The BSM Warning Light may even
remain illuminated the entire time the vehicle is
in a forward gear.
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.

230SAFETY
The Blind Spot Monitoring (BSM) system may
experience dropouts (blinking on and off) of the
side mirror warning indicator lamps when a
motorcycle or any small object remains at the
side of the vehicle for extended periods of time
(more than a couple of seconds).
The area on the rear fascia/bumper 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/bumper where the
radar sensors are located with foreign objects
(bumper stickers, bicycle racks, etc.).

Sensor Location
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 on. 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, cycle the
ignition from on to off and then back on again to
reset the system.
If the blockage message is still present after
cycling the ignition and driving in traffic, check
again for a blockage.
The BSM system notifies the driver of objects in the
detection zones by illuminating the BSM Warning
Light located in the outside mirrors in addition to
sounding an audible (chime) alert and reducing the
radio volume Ú
page 232.

Warning Light Location
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.
Entering From The Side
Vehicles that move into your adjacent lanes from
either side of the vehicle.

Side Monitoring

22_RUP_OM_EN_USC_t.book Page 230

SAFETY231
Entering From The Rear
Vehicles that come up from behind your vehicle on
either side and enter the rear detection zone with
a relative speed of less than 30 mph (48 km/h).

Rear Monitoring

Overtaking Traffic
If you pass another vehicle slowly with a relative
speed less than 15 mph (24 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 15 mph (24 km/h), the warning
light will not illuminate.
Overtaking/Approaching
Overtaking/Passing

The BSM system is designed not to issue an alert
on stationary objects such as guardrails, posts,
walls, foliage, berms, snow banks, car washes, 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 Ú
page 370.

Opposing Traffic

WARNING!
The Blind Spot Monitoring system is only an aid
to help detect objects in the blind spot zones.
The BSM system is not designed 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
shoulder, and use your turn signal before
changing lanes. Failure to do so can result in
serious injury or death.

232SAFETY
Rear Cross Path (RCP)
RCP is intended to aid the driver when backing out
of parking spaces where their vision of oncoming
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 Detection Zones

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
blocked 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. Additionally, if your vehicle is obscured by a
flat object on one side the system can false alert
on vehicles approaching from the opposite
direction.
When RCP is on and the vehicle is in REVERSE (R),
the driver is alerted using both the visual and
audible alarms, including reducing the radio
volume.Blind Spot Modes
Three selectable modes of operation are available
in the Uconnect system.
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 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.
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.
NOTE:Whenever an audible alert is requested by the
BSM system, the radio is also muted.
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.

22_RUP_OM_EN_USC_t.book Page 232

236SAFETY
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.
NOTE:The PEB system will NOT retain the last setting
selected by the driver after ignition shut down. The
system will reset to the default setting when the
vehicle is restarted.
TIRE PRESSURE MONITORING SYSTEM
(TPMS)
The Tire Pressure Monitoring System (TPMS) will
warn the driver of a low tire pressure based on the
vehicle recommended cold placard pressure.
NOTE:The TPMS 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 graphic showing the pressure values of
each tire with the low tire pressure values in a
different color, or the Uconnect radio will display a
TPMS message. When this occurs you must
increase the tire pressure to the recommended
cold placard pressure in order for the TPMS
Warning Light to turn off. 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.
See Ú
page 346 for information on how to
properly inflate the vehicle’s tires.
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. Once the
low tire pressure warning (TPMS Warning Light)
illuminates, you must increase the tire pressure to
the recommended cold placard pressure in order
for the TPMS Warning Light to turn 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 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
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 Warning Light will
turn off only after the tires are inflated to the
vehicle’s recommended cold placard pressure
value Ú
page 370.
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 TPMS Warning Light off.

22_RUP_OM_EN_USC_t.book Page 236

SAFETY237
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 TPMS 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 display in the instrument
cluster
Tire Pressure Monitoring System Warning Light
SERVICE TPMS WARNING
When a system fault is detected, the Tire Pressure
Monitoring System (TPMS) 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 SYSTEM" 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.
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.
