2018 JEEP GRAND CHEROKEE LIMITED Owners Manual

The BSM system is designed not to issue an alert on
stationary objects such as guardrails, posts, walls, foliage,
berms, etc. However, occasionally the system may alert on
such objects. This is normal operation and your vehicle
does not require service.The BSM system will not alert you of objects that are
traveling in the opposite direction of the vehicle in adjacent
lanes.

WARNING!(Continued)
or animals. Even if your vehicle is equipped with the
BSM system, always check your vehicle’s mirrors,
glance over your shoulder, and use your turn signal
before changing lanes. Failure to do so can result in
serious injury or death.
Rear Cross Path (RCP)
The Rear Cross Path (RCP) feature is intended to aid the
driver when backing out of parking spaces where their
vision of oncoming vehicles may be blocked. Proceed
slowly and cautiously out of the parking space until the
rear end of the vehicle is exposed. The RCP system will
then have a clear view of the cross traffic and if an
oncoming vehicle is detected, alert the driver. 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.

When RCP is on and the vehicle is in REVERSE, the driver
is alerted using both the visual and audible alarms, includ-
ing reducing the radio volume.

If a Forward Collision Warning with Mitigation event
begins at a speed below 26 mph (42 km/h), the system may
provide the maximum or partial braking to mitigate the
potential forward collision. If the Forward Collision Warn-
ing with Mitigation event stops the vehicle completely, the
system will hold the vehicle at a 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.
• It is unsafe to test the FCW system. To prevent such
misuse of the system, after four Active Braking events
within an ignition cycle, the Active Braking portion of
FCW will be deactivated until the next ignition cycle.
• The FCW system is intended for on-road use only. If the
vehicle is taken off-road, the FCW system should be
deactivated to prevent unnecessary warnings to the
surroundings. If the vehicle enters 4WD Low Range or
ESC Full-Off Mode is active, the FCW system will be
automatically deactivated.

WARNING!(Continued)
type of potential collision. The driver has the respon-
sibility to avoid a collision by controlling the vehicle
via braking and steering. Failure to follow this warn-
ing could lead to serious injury or death.
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
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.
