2017 CHRYSLER PACIFICA sensor

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
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 de-
tection 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 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 (bum-
per stickers, bicycle racks, etc.).
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 area around the sensors of the

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. Additionally, if
the host 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, the
driver is alerted using both the visual and audible
alarms, including reducing the radio volume.
WARNING!
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

Forward Collision Warning (FCW) With Mitigation
— If Equipped
The Forward Collision Warning (FCW) system with
mitigation provides the driver with audible warnings,
visual warnings (within the EVIC/DID), 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 deter-
mines 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 maxi-
mum braking possible to mitigate the potential forward
collision. If the Forward Collision Warning with Mitiga-
tion event stops the vehicle completely, the system will
hold the vehicle at standstill for two seconds and then
release the brakes.

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 op-
eration or sensor damage may result when using
replacement equipment that is not of the same size,
type, and/or style. Aftermarket wheels can cause
sensor damage.
• Using aftermarket tire sealants may cause the Tire
Pressure Monitoring System (TPMS) sensor to be-
come inoperable. After using an aftermarket tire
sealant it is recommended that you take your
vehicle to an authorized dealership to have your
sensor function checked.
• After inspecting or adjusting the tire pressure al-
ways reinstall the valve stem cap. This will prevent
(Continued)
CAUTION! (Continued)
moisture and dirt from entering the valve stem,
which could damage the TPMS sensor.
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. Underin-
flation 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 mainte-
nance, and it is the driver ’s responsibility to maintain
5
SAFETY 295

correct tire pressure using an accurate tire pressure
gauge, even if underinflation has not reached the level
to trigger illumination of the “Tire Pressure Monitor-
ing Telltale Light”.
• Seasonal temperature changes will affect tire pressure,
and the TPMS will monitor the actual tire pressure in
the tire.
Base 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 components:
•
Receiver Module
• Four Tire Pressure Monitoring Sensors
• Tire Pressure Monitoring Telltale Light
Tire Pressure Monitoring Low Pressure Warnings
The “Tire Pressure Monitoring Telltale Light” will
illuminate in the instrument cluster, a “LOW TIRE
PRESSURE” message will display in the instrument
cluster, an Inflate to XX message will be displayed and
a chime will sound when tire pressure is low in one or
more of the four active road tires. Should this occur, you
should stop as soon as possible, check the inflation
pressure of each tire on your vehicle, and inflate each tire
to the vehicle’s recommended cold placard pressure
value as shown in the Inflate to XXmessage. Once the
296 SAFETY

system receives the updated tire pressures, the system
will automatically update and the “Tire Pressure Moni-
toring Telltale 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 placard pressure in order
to turn the Tire Pressure Monitoring Telltale Light off.
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.
Service TPMS Warning
When a system fault is detected, the “Tire Pressure
Monitoring Telltale Light” will flash on and off for 75
seconds and then remain on solid. The system fault will
also sound a chime. If the ignition is cycled, this sequence
will repeat, providing the system fault still exists. The “Tire Pressure Monitoring Telltale Light” will turn off
when the fault condition no longer exists. A system fault
can occur due to any of the following:
1. Jamming due to electronic devices or driving next to
facilities emitting the same radio frequencies as the
TPMS sensors.
2. Installing some form of aftermarket window tinting that affects radio wave signals.
3. Lots of snow or ice around the wheels or wheel housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPMS sensors.
Vehicles With Compact Spare
1. The compact spare tire does not have a tire pressure monitoring sensor. Therefore, the TPMS will not moni-
tor the pressure in the compact spare tire.

SAFETY 297

2. If you install the compact or non-matching full sizespare tire in place of a road tire that has a pressure
below the low-pressure warning limit, a chime will
sound and the “TPMS Telltale Light” and “LOW TIRE
PRESSURE” and Inflate to XXmessages will turn on
upon the next ignition cycle.
3. After driving the vehicle for up to 20 minutes above 15 mph (24 km/h), the “TPMS Telltale Light” will
flash on and off for 75 seconds and then remain on
solid.
4. For each subsequent ignition cycle, a chime will sound and the “TPMS Telltale Light” will flash on and off for
75 seconds and then remain on solid.
5. Once you repair or replace the original road tire and reinstall it on the vehicle in place of the compact spare
or non-matching full size spare, the TPMS will update
automatically and the “TPMS Telltale Light” will turn off, as long as no tire pressure is below the low-
pressure warning limit in any of the four active road
tires. 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.
