2023 CHRYSLER PACIFICA HYBRID brake sensor

SAFETY189
Electronic Stability Control (ESC)
ESC enhances directional control and stability of the
vehicle under various driving conditions. ESC corrects for
oversteering or understeering of the vehicle by applying
the brake of the appropriate wheel(s) to assist in
counteracting these conditions. Engine power may also be
reduced to help the vehicle maintain the desired path.
Oversteer — when the vehicle is turning more than
appropriate for the steering wheel position.
 Understeer — when the vehicle is turning less than
appropriate for the steering wheel position.
ESC uses sensors in the vehicle to determine the vehicle
path intended by the driver and compares it to the actual
path of the vehicle. When the actual path does not match
the intended path, ESC applies the brake of the
appropriate wheel to assist in counteracting the oversteer
or understeer condition.
The ESC Activation/Malfunction Indicator Light located in
the instrument cluster will start to flash as soon as the ESC
system becomes active. The ESC Activation/Malfunction
Indicator Light also flashes when the 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.
ESC Operating Modes
Depending upon model and mode of operation, the ESC
system may have multiple operating modes.
ESC On
This is the normal operating mode for the ESC. Whenever
the vehicle is started, the ESC system will be in this mode.
This mode should be used for most driving conditions.
Alternate ESC modes should only be used for specific
reasons as noted in the following paragraphs.
Partial Off
This mode may be useful if the vehicle becomes stuck.
This mode may modify TCS and ESC thresholds for
activation, which allows for more wheel spin than normally
allowed.
To enter the “Partial Off” mode, momentarily push the ESC
OFF button and the ESC OFF Indicator Light will illuminate.
To turn the ESC on again, momentarily push the ESC OFF
button and the ESC OFF Indicator Light will turn off.
NOTE:When driving with snow chains, or when starting off in
deep snow, sand, or gravel, it may be desirable to allow
more wheel spin. This can be accomplished by momen
-
tarily pushing the ESC OFF button to enter partial mode
“Partial Off” mode. Once the situation requiring “Partial
Off” mode is overcome, turn ESC back on by momentarily
pushing the ESC OFF button. This may be done while the
vehicle is in motion.
WARNING!

Many factors, such as vehicle loading, road conditions
and driving conditions, influence the chance that wheel
lift or rollover may occur. ERM cannot prevent all wheel
lift or rollovers, especially those that involve leaving the
roadway or striking objects or other vehicles. The
capabilities of an ERM-equipped vehicle must never be
exploited in a reckless or dangerous manner which could
jeopardize the user's safety or the safety of others.

WARNING!

 Electronic Stability Control (ESC) cannot prevent the
natural laws of physics from acting on the vehicle, nor
can it increase the traction afforded by prevailing road
conditions. ESC cannot prevent accidents, including
those resulting from excessive speed in turns, driving
on very slippery surfaces, or hydroplaning. ESC also
cannot prevent accidents resulting from loss of vehicle
control due to inappropriate driver input for the condi -
tions. Only a safe, attentive, and skillful driver can
prevent accidents. The capabilities of an ESC
equipped vehicle must never be exploited in a reckless
or dangerous manner which could jeopardize the
user’s safety or the safety of others.

 Vehicle modifications, or failure to properly maintain
your vehicle, may change the handling characteris -
tics of your vehicle, and may negatively affect the
performance of the ESC system. Changes to the
steering system, suspension, braking system, tire
type and size or wheel size may adversely affect ESC
performance. Improperly inflated and unevenly worn
tires may also degrade ESC performance. Any vehicle
modification or poor vehicle maintenance that
reduces the effectiveness of the ESC system can
increase the risk of loss of vehicle control, vehicle
rollover, personal injury and death.

192SAFETY
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
Úpage 147.
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 (BSM) —
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. 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 false
detections. The BSM Warning Light may even remain
illuminated the entire time the vehicle is in a forward
gear.
 The Blind Spot Monitoring (BSM) system may experi -
ence dropouts (blinking on and off) of the side mirror
warning indicator lights 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

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.

SAFETY195
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.
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
is also muted. 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.
 The BSM system can work in conjunction with the
KeySense function of the vehicle (if equipped)
Úpage 98.
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.
If a FCW with Mitigation event begins at a speed below
37 mph (60 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. If a pedestrian is encountered in the path at
the same speed threshold, the system will attempt to
bring the vehicle to a stop.

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 312.
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.
