uconnect CHRYSLER PACIFICA 2019 Service Manual

Changing the FCW status to “off” deactivates the system,
so no warning or active braking will be available in case of
a possible collision
NOTE:
•The FCW system state is kept in memory from one key
cycle to the next. If the system is turned off, it will
remain off when the vehicle is restarted.
• FCW can work in conjunction with the KeySense func-
tion of the vehicle if equipped. Refer to “KeySense
Cluster Messages in “Getting To Know Your Instrument
Panel” for further information.
FCW Braking Status And Sensitivity
The FCW Sensitivity and Active Braking status are program-
mable through the Uconnect System. Refer to “Uconnect
Settings” in “Multimedia” for further information.
The default sensitivity of FCW is the “Medium” setting
and the system status is “Warning & Braking”. This allows
the system to warn the driver of a possible collision with
the vehicle in front using audible/visual warnings and it
applies autonomous braking.
Changing the FCW status to “Far” setting allows the system
to warn the driver of a possible collision with the vehicle in front using audible/visual warning when the latter is at a
farther distance than
Mediumsetting. This provides the
most reaction time to avoid a possible collision.
Changing the FCW status to the “Near” setting, allows the
system to warn the driver of a possible collision with the
vehicle in front when the distance between the vehicle in
the front is much closer. This setting provides less reaction
time than the “Far” and “Medium” settings, which allows
for a more dynamic driving experience.
NOTE:
• Changing the FCW status to “Only Warning” prevents
the system from providing limited active braking, or
additional brake support if the driver is not braking
adequately in the event of a potential frontal collision,
but maintains the audible and visual warnings.
• Changing the FCW status to “Off” prevents the system
from providing autonomous braking, or additional
brake support if the driver is not braking adequately in
the event of a potential frontal collision.
• The system will retain the last setting selected by the
driver after ignition shut down.
• FCW may not react to irrelevant objects such as over-
head objects, ground reflections, objects not in the path

Tire Pressure Monitor System (TPMS)
The Tire Pressure Monitor System (TPMS) will warn the
driver of a low tire pressure based on the vehicle recom-
mended 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 approxi-
mately 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. Refer to “Tires” in “Servicing and Mainte-
nance” 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 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

You can engage the park brake in two ways;
•Manually, by applying the park brake switch.
• Automatically, by enabling the Auto Park Brake feature
in the customer programmable features section of the
Uconnect Settings.
The park brake switch is located in the integrated center
stack.
To apply the park brake manually, push the switch mo-
mentarily. You may hear a slight whirring sound from the
back of the vehicle while the park brake engages. Once the
park brake is fully engaged, the BRAKE warning lamp in the instrument cluster and an indicator on the switch will
illuminate. If your foot is on the brake pedal while you
apply the park brake, you may notice a small amount of
brake pedal movement. The park brake can be applied
even when the ignition switch is OFF, however, it can only
be released when the ignition switch in the ACC or
ON/RUN position.
NOTE:
The EPB fault lamp will illuminate if the EPB
switch is held for longer than 180 seconds. The light will
extinguish upon releasing the switch.
If the Auto Park Brake feature is enabled, the parking brake
will automatically engage whenever the transmission is
placed into PARK. Once the park brake is engaged, the
BRAKE warning lamp in the instrument cluster and the
LED indicator on the switch will illuminate. If your foot is
on the brake pedal, you may notice a small amount of
brake pedal movement while the parking brake is engag-
ing.
The park brake will release automatically when the igni-
tion is cycled to the ON/RUN position, the transmission is
in DRIVE or REVERSE, and the driver seat belt is buckled
and an attempt is made to drive the vehicle away by
pressing the accelerator pedal.

PARK. Failure to do so may allow the vehicle to roll
and cause damage or injury.
• Driving the vehicle with the parking brake engaged,
or repeated use of the parking brake to slow the
vehicle may cause serious damage to the brake
system.
CAUTION!
If the Brake System Warning Light remains on with the
parking brake released, a brake system malfunction is
indicated. Have the brake system serviced by an au-
thorized dealer immediately.
If exceptional circumstances should make it necessary to
engage the park brake while the vehicle is in motion, push
on the electric park brake switch for as long as engagement
is desired. The BRAKE warning lamp will illuminate, and
a continuous chime will sound. The rear stop lamps will
also be illuminated automatically while the vehicle re-
mains in motion.
To disengage the park brake while the vehicle is in motion,
release the switch. If the vehicle is brought to a complete stop using the park brake, when the vehicle reaches
approximately 3 mph (4.8 km/h), the park brake will
remain engaged.
In the unlikely event of a malfunction of the Electric Park
Brake system, a yellow EPB fault lamp will illuminate. This
may be accompanied by the BRAKE warning lamp flash-
ing. In this case, urgent service of the electric park brake
system is required. Do not rely on the park brake to hold
the vehicle stationary.Auto Park Brake
The Electric Park Brake can be programmed to be applied
automatically whenever the vehicle is at a standstill and
the automatic transmission is placed in PARK. Auto Park
Brake is enabled and disabled by customer selection
through the “Customer Programmable Features” section of
the “Uconnect Settings”.
SafeHold
SafeHold is a safety feature of the Electric Park Brake
System that will engage the park brake automatically if the
vehicle is left unsecured. If the automatic transmission is
not in PARK, the seat belt is unbuckled, the driver door is
open, the vehicle is at a standstill, and there is no attempt

to depress the brake pedal or accelerator pedal, the park
brake will automatically engage to prevent the vehicle
from rolling.
SafeHold can be temporarily bypassed by pushing the
Electric Park Brake Switch while the driver door is open
and brake pedal is pressed. Once manually bypassed,
SafeHold will be enabled again once the vehicle reaches
12 mph (20 km/h) or the ignition is cycled to the OFF
position and back to ON again.
Brake Service Mode
We recommend having your brakes serviced by your
authorized dealer. You should only make repairs for which
you have the knowledge and the right equipment. You
should only enter Brake Service Mode during brake ser-
vice.
When servicing your rear brakes, it may be necessary for
you or your technician to push the rear piston into the rear
caliper bore. With the Electric Park Brake system, this can
only be done after retracting the Electric Park Brake
actuator. Fortunately, actuator retraction can be done easily
by entering the “Brake Service” through the “Uconnect
Settings” in your vehicle. This menu based system will
guide you through the steps necessary to retract the EPB
actuator in order to perform rear brake service.Brake Service Mode has requirements that must be met in
order to be activated:
•
The vehicle must be at a standstill.
• The park brake must be unapplied.
• The transmission must be in PARK or NEUTRAL.
While in service mode, the Electric Park Brake fault lamp
will flash continuously while the ignition switch is ON.
When brake service work is complete, the following steps
must be followed to reset the parking brake system to
normal operation:
• Ensure the vehicle is at a standstill.
• Press the brake pedal with moderate force.
• Apply the Electric Park Brake Switch.
WARNING!
You can be badly injured working on or around a
motor vehicle. Do only that service work for which you
have the knowledge and the right equipment. If you
have any doubt about your ability to perform a service
job, take your vehicle to a competent mechanic.
