2018 CHRYSLER PACIFICA brake sensor

Electronic Stability Control (ESC)
This system enhances directional control and stability of
the vehicle under various driving conditions. ESC corrects
for oversteering or understeering of the vehicle by apply-
ing the brake of the appropriate wheel(s) to assist in
counteracting the oversteer or understeer condition. En-
gine power may also be reduced to help the vehicle
maintain the desired path.
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.
•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.
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.
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 con-
ditions. 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 us-
er ’s safety or the safety of others.

Vehicle modifications, or failure to properly main-
tain your vehicle, may change the handling charac-
teristics of your vehicle, and may negatively affect

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 resum-
ing acceleration, manually activate the trailer brake
or apply more vehicle brake pressure prior to releas-
ing 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.
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, refer to
“Uconnect Settings” in “Multimedia” for further infor-
mation.
Rain Brake Support (RBS)
Rain Brake Support 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 interac-
tion is required.
Ready Alert Braking (RAB)
Ready Alert Braking may reduce the time required to reach
full braking during emergency braking situations. It antici-
pates when an emergency braking situation may occur by
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 automati-
cally once an excessively swaying trailer is recognized.
Note that TSC cannot stop all trailers from swaying.
Always use caution when towing a trailer and follow the
trailer tongue weight recommendations. Refer to “Trailer
222 SAFETY

Towing” in “Starting And Operating” for further informa-
tion. 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.
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,
motorcycles, 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 outside 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 approximately one lane
width on both sides of the vehicle 12 ft (3.8 m). The zone
length starts at the outside rear view mirror and extends
approximately 10 ft (3 m) beyond the rear bumper of the
vehicle. The BSM system monitors the detection zones on
Rear Detection Zones

SAFETY 223

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 pro-
gressive 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
26 mph (42 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. When the system determines a collision with the vehicle in
front of you is no longer probable, the warning message
will be deactivated.
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.

SAFETY 231

ACC will allow you to keep cruise control engaged in light
to moderate traffic conditions without the constant need to
reset your cruise control. ACC utilizes a radar sensor and a
forward facing camera designed to detect a vehicle directly
ahead of you.
NOTE:
•If the sensor does not detect a vehicle ahead of you, ACC
will maintain a fixed set speed.
• If the ACC sensor detects a vehicle ahead, ACC will
apply limited braking or accelerate (not to exceed the
original set speed) automatically to maintain a preset
following distance, while matching the speed of the
vehicle ahead.
The Cruise Control system has two control modes:
• Adaptive Cruise Control mode for maintaining an ap-
propriate distance between vehicles.
• Normal (Fixed Speed) Cruise Control mode for cruising
at a constant preset speed. For additional information,
refer to “Normal (Fixed Speed) Cruise Control Mode” in
this section.
NOTE:
Normal (Fixed Speed) Cruise Control will not react
to preceding vehicles. Always be aware of the mode selected.
You can change the mode by using the Cruise Control
buttons. The two control modes function differently. Al-
ways confirm which mode is selected.
WARNING!
• Adaptive Cruise Control (ACC) is a convenience
system. It is not a substitute for active driving
involvement. It is always the driver ’s responsibility
to be attentive of road, traffic, and weather condi-
tions, vehicle speed, distance to the vehicle ahead;
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 and death or serious personal injury.
• The ACC system:
• Does not react to pedestrians, oncoming vehicles,
and stationary objects (e.g., a stopped vehicle in a
traffic jam or a disabled vehicle).
• Cannot take street, traffic, and weather conditions
into account, and may be limited upon adverse
sight distance conditions.

The vehicle will then maintain the set distance until:
•The vehicle ahead accelerates to a speed above the set
speed.
• The vehicle ahead moves out of your lane or view of the
sensor.
• The distance setting is changed.
• The system disengages. (Refer to the information on
ACC Activation).
The maximum braking applied by ACC is limited; how-
ever, the driver can always apply the brakes manually, if
necessary.
NOTE: The brake lights will illuminate whenever the ACC
system applies the brakes.
A Proximity Warning will alert the driver if ACC predicts
that its maximum braking level is not sufficient to maintain
the set distance. If this occurs, a visual alert “BRAKE” will
flash in the instrument cluster display and a chime will
sound while ACC continues to apply its maximum braking
capacity. NOTE:
The “Brake!” Screen in the instrument cluster
display is a warning for the driver to take action and does
not necessarily mean that the Forward Collision Warning
system is applying the brakes autonomously.
Overtake Aid
When driving with ACC engaged and following a vehicle,
the system will provide an additional acceleration up to the
ACC set speed to assist in passing the vehicle. This
additional acceleration is triggered when the driver utilizes
the left turn signal and will only be active when passing on
the left hand side.

STARTING AND OPERATING 341

WARNING!
•Drivers must be careful when backing up even when
using ParkSense. 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. You are respon-
sible for safety and must continue to pay attention to
your surroundings. Failure to do so can result in
serious injury or death.
• Before using ParkSense, it is strongly recommended
that the ball mount and hitch ball assembly is
disconnected from the vehicle when the vehicle is
not used for towing. Failure to do so can result in
injury or damage to vehicles or obstacles because the
hitch ball will be much closer to the obstacle than the
rear fascia when the loudspeaker sounds the con-
tinuous tone. Also, the sensors could detect the ball
mount and hitch ball assembly, depending on its size
and shape, giving a false indication that an obstacle
is behind the vehicle.
CAUTION!
•ParkSense is only a parking aid and it is unable to
recognize every obstacle, including small obstacles.
Parking curbs might be temporarily detected or not
detected at all. Obstacles located above or below the
sensors will not be detected when they are in close
proximity.
• The vehicle must be driven slowly when using
ParkSense in order to be able to stop in time when an
obstacle is detected. It is recommended that the
driver looks over his/her shoulder when using
ParkSense.
PARKSENSE FRONT AND REAR PARK ASSIST —
IF EQUIPPED
The ParkSense Park Assist system provides visual and
audible indications of the distance between the rear and/or
front fascia and a detected obstacle when backing up or
moving forward, e.g. during a parking maneuver. If your
vehicle is equipped with an Automatic Transmission, the
vehicle brakes may be automatically applied and released
when performing a reverse parking maneuver if the sys-
tem detects a possible collision with an obstacle.

PARKSENSE ACTIVE PARK ASSIST SYSTEM — IF
EQUIPPED
The ParkSense Active Park Assist system is intended to
assist the driver during parallel and perpendicular parking
maneuvers by identifying a proper parking space, provid-
ing audible/visual instructions, and controlling the steer-
ing wheel. The ParkSense Active Park Assist system is
defined as “semi-automatic” since the driver maintains
control of the accelerator, gear selector and brakes. De-
pending on the driver’s parking maneuver selection, the
ParkSense Active Park Assist system is capable of maneu-
vering a vehicle into a parallel or a perpendicular parking
space on either side (i.e., driver side or passenger side).
