Tire Pressure Monitor System (Tpms) - Jeep Cherokee 2018 Owner's Manual

To turn the FCW system off, push the forward
collision button once (LED turns on).
To turn the FCW system back on, push the
forward collision button again (LED turns off).
• Changing the FCW status to "off" prevents
the system from warning you of a possible
collision with the vehicle in front of you.
• Changing the FCW sensitivity - Near vs. Far.
Far warns the driver of a possible collision
earlier and Near warns the driver later.
• Changing the Active Braking status to "off"
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 main-
tains the audible and visual warnings.
NOTE:
The FCW system state is defaulted to ON from
one ignition cycle to the next. If the system is
turned OFF, it will reset to ON when the vehicle
is restarted.
Changing FCW And Active Braking Status
The FCW Sensitivity And Active Braking Set-
tings are programmable through the Uconnect
System. Refer to "Uconnect Settings" in "Multi-
media" for further information.
The default status of FCW is the "Far" setting
and the Active Braking is the "On" setting, this
allows the system to warn you of a possible
collision with the vehicle in front of you when you
108
are farther away and it applies limited braking.
This gives you the most reaction time to avoid a
possible collision.
Changing the FCW status to the "Near" setting,
allows the system to warn you of a possible
collision with the vehicle in front of you when you
are much closer. This setting provides less
reaction time than the "Far" setting, which allows
for a more dynamic driving experience.
NOTE:
• The system will NOT retain the last setting
selected by the driver after ignition shut
down. The system will reset to default setting
when the vehicle is restarted.
• FCW may not react to irrelevant objects such
as overhead objects, ground reflections, ob-
jects not in the path of the vehicle, stationary
objects that are far away, oncoming traffic, or
leading vehicles with the same or higher rate
of speed.
• FCW will be disabled like ACC, with the
unavailable screens.
FCW Limited Warning
If the instrument cluster display reads "ACC/
FCW Limited Functionality" or "ACC/FCW Lim-
ited Functionality Clean Front Windshield" mo-
mentarily, there may be a condition that limits
FCW functionality. Although the vehicle is still
drivable under normal conditions, the active
braking may not be fully available. Once the
condition that limited the system performance is
no longer present, the system will return to its
full performance state. If the problem persists,
see your authorized dealer.
Service FCW Warning
If the system turns off, and the instrument
cluster display reads:
• ACC/FCW Unavailable Service Required
• Cruise/FCW Unavailable Service Required
This indicates there is an internal system fault.
Although the vehicle is still drivable under nor-
mal conditions, have the system checked by an
authorized dealer.
Tire Pressure Monitor System
(TPMS)
The Tire Pressure Monitor System (TPMS) will
warn the driver of a low tire pressure based on
the vehicle recommended cold placard pres-
sure.
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 tem-
perature decreases, the tire pressure will de-
crease. 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 Maintenance" for information on
how to properly inflate the vehicle's tires. The
