2020 JEEP GRAND CHEROKEE Owner handbook (in English)

NOTE:
During HDC the +/- shifter input is used for
HDC target speed selection, but will not af-
fect the gear chosen by the transmission.
When actively controlling HDC the transmis-
sion will shift appropriately for the driver-
selected set speed and corresponding driving
conditions.
Driver Override
The driver may override HDC activation with
throttle or brake application at anytime.
Deactivating HDC
HDC will be deactivated but remain available
if any of the following conditions occur:
• Driver overrides HDC set speed with throttle
or brake application.
• Vehicle speed exceeds 20 mph (32 km/h)
but remains below 40 mph (64 km/h).
• Vehicle is on a downhill grade of insuffi-
cient magnitude, is on level ground, or is on
an uphill grade.
• Vehicle is shifted to park.Disabling HDC
HDC will be deactivated and disabled if any
of the following conditions occur:
• The driver pushes the HDC switch.
• The driveline is shifted out of 4WD Low
Range.
• The parking brake is applied.
• Driver door opens.
• The vehicle is driven greater than 20 mph
(32 km/h) for greater than 70 seconds.
• The vehicle is driven greater than 40 mph
(64 km/h) (HDC exits immediately).
• HDC detects excessive brake temperature.
Feedback To The Driver
The instrument cluster has an HDC icon and
the HDC switch has an LED icon, which offers
feedback to the driver about the state HDC is
in.
• The cluster icon and switch lamp will illu-
minate and remain on solid when HDC is
enabled or activated. This is the normal
operating condition for HDC.• The cluster icon and switch lamp will flash
for several seconds then extinguish when
the driver pushes the HDC switch but en-
able conditions are not met.
• The cluster icon and switch lamp will flash
for several seconds then extinguish when
HDC disables due to excess speed.
• The cluster icon and switch lamp will flash
when HDC deactivates due to overheated
brakes. The flashing will stop and HDC will
activate again once the brakes have cooled
sufficiently.
WARNING!
HDC is only intended to assist the driver in
controlling vehicle speed when descend-
ing hills. The driver must remain attentive
to the driving conditions and is responsible
for maintaining a safe vehicle speed.
Selec Speed Control (SSC) — If Equipped
SSC is intended for off road driving in 4WD
Low Range only. SSC maintains vehicle
speed by actively controlling engine torque
and brakes.
95

SSC has three states:
1. Off (feature is not enabled and will not
activate).
2. Enabled (feature is enabled and ready but
activation conditions are not met, or
driver is actively overriding with brake or
throttle application).
3. Active (feature is enabled and actively
controlling vehicle speed).
Enabling SSC
SSC is enabled by pushing the SSC switch,
but the following conditions must also be met
to enable SSC:
• Driveline is in 4WD Low Range.
• Vehicle speed is below 5 mph (8 km/h).
• Parking brake is released.
• Driver door is closed.
• Driver is not applying throttle.Activating SSC
Once SSC is enabled it will activate automati-
cally once the following conditions are met:
• Driver releases throttle.
• Driver releases brake.
•
Transmission is in any selection other than P.
• Vehicle speed is below 20 mph (32 km/h).
The set speed for SSC is selectable by the
driver, and can be adjusted by using the gear
shift +/-. Additionally, the SSC set speed may
be reduced when climbing a grade and the
level of set speed reduction depends on the
magnitude of grade. The following summa-
rizes the SSC set speeds:
SSC Target Set Speeds
• 1st = .6 mph (1 km/h)
• 2nd = 1.2 mph (2 km/h)
• 3rd = 1.8 mph (3 km/h)
• 4th = 2.5 mph (4 km/h)
• 5th = 3.1 mph (5 km/h)
• 6th = 3.7 mph (6 km/h)
• 7th = 4.3 mph (7 km/h)• 8th = 5 mph (8 km/h)
• 9th = 5.6 mph (9 km/h) – If Equipped
• REVERSE = .6 mph (1 km/h)
• NEUTRAL = 1.2 mph (2 km/h)
• PARK = SSC remains enabled but not
active
NOTE:
• During SSC the +/- shifter input is used for
SSC target speed selection but will not
affect the gear chosen by the transmission.
While actively controlling SSC the trans-
mission will shift appropriately for the
driver-selected set speed and correspond-
ing driving conditions.
• SSC performance is influenced by the Ter-
rain Select mode. This difference may be
notable to the driver and may be perceived
as a varying level of aggressiveness.
Driver Override:
The driver may override SSC activation with
throttle or brake application at any time.

SSC is only intended to assist the driver in
controlling vehicle speed when driving in
off road conditions. The driver must re-
main attentive to the driving conditions
and is responsible for maintaining a safe
vehicle speed.
AUXILIARY DRIVING
SYSTEMS
Blind Spot Monitoring (BSM) — If
Equipped
The Blind Spot Monitoring (BSM) system
uses two radar sensors, located inside the
rear bumper fascia, to detect highway licens-
able vehicles (automobiles, trucks, motor-
cycles, etc.) that enter the blind spot zones
from the rear/front/side of the vehicle.
97

When the vehicle is started, the BSM warning
light will momentarily illuminate in both out-
side 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.
The BSM detection zone covers approxi-
mately one lane width on both sides of the
vehicle 12 ft (3.8 m). The zone length starts
at the side of the vehicle, near the B-Pillar,
and extends approximately 10 ft (3 m) be-
yond the rear bumper of the vehicle. The
BSM system monitors the detection zones on
both sides of the vehicle when the vehiclespeed 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 detection 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 equip-
ment) extends beyond the side of your ve-
hicle, this may result in random false de-
tections on the trailer, and false chimes
when the turn signal is used.
• The Blind Spot Monitoring (BSM) system
may experience drop outs (blinking on and
off) of the side mirror Warning Indicator
lamps when a motorcycle or any small ob-
ject remains at the side of the vehicle for
extended periods of time (more than a
couple of seconds).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
(bumper stickers, bicycle racks, etc.).
The BSM system notifies the driver of objects
in the detection zones by illuminating the
BSM warning light located in the outside
mirrors. In addition, when the turn signal is
activated during the alert on the side of the
vehicle corresponding to the alert, an audible
(chime) alert can be heard. During this au-
dible (chime) alert, the radio volume will be
reduced. Refer to “Modes Of Operation” in
this section for further information.
Rear Detection Zones
SAFETY
98

The BSM system monitors the detection zone
from three different entry points (side, rear,
front) while driving to see if an alert is neces-
sary. The BSM system will issue an alert
during these types of zone entries.
Entering From The Side
Vehicles that move into your adjacent lanes
from either side of the vehicle.Entering From The Rear
Vehicles that come up from behind your ve-
hicle on either side and enter the rear detec-
tion zone with a relative speed of less than
30 mph (48 km/h).
Overtaking Traffic
If you pass another vehicle slowly with a
relative speed less than 15 mph (24 km/h)
and the vehicle remains in the blind spot for
approximately 1.5 seconds, the warning light
will be illuminated. If the difference in speed
between the two vehicles is greater than
15 mph (24 km/h), the warning light will not
illuminate.
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!
The Blind Spot Monitoring system is only
an aid to help detect objects in the blind
spot zones. The BSM system is not de-
signed to detect pedestrians, bicyclists, or
animals. Even if your vehicle is equipped
with the BSM system, always check your
vehicle’s mirrors, glance over your shoul-
der, and use your turn signal before chang-
ing lanes. Failure to do so can result in
serious injury or death.
Rear Cross Path (RCP)
The Rear Cross Path (RCP) feature is in-
tended to aid the driver when backing out of
parking spaces where their vision of oncom-
ing 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 5 mphBlind Spot Warning Light
99

(8 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 RE-
VERSE, the driver is alerted using both the
visual and audible alarms, including reduc-
ing the radio volume.
WARNING!
Rear Cross Path Detection (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
be sure to check for pedestrians, animals,
other vehicles, obstructions, and blind
spots before backing up. Failure to do so
can result in serious injury or death.
Modes Of Operation
Three selectable modes of operation are
available in the Uconnect System. Refer to
“Uconnect Settings” in “Multimedia” in the
Owner’s Manual for further information.
Blind Spot Alert Lights Only
When operating in Blind Spot Alert mode, the
BSM system will provide a visual alert in the
appropriate side view mirror based on a de-
tected object. However, when the system is
operating in Rear Cross Path (RCP) mode, the
system will respond with both visual and
audible alerts when a detected object is pres-
ent. Whenever an audible alert is requested,
the radio is muted.
Blind Spot Alert Lights/Chime
When operating in Blind Spot Alert Lights/
Chime mode, the BSM system will provide a
visual alert in the appropriate side view mirror
based on a detected object. If the turn signal
is then activated, and it corresponds to an
alert present on that side of the vehicle, an
audible chime will also be sounded. When-
ever a turn signal and detected object are
present on the same side at the same time,both the visual and audible alerts will be
issued. In addition to the audible alert the
radio (if on) will also be muted.
NOTE:
Whenever an audible alert is requested by the
BSM system, the radio is also muted.
When the system is in RCP, the system shall
respond with both visual and audible alerts
when a detected object is present. Whenever
an audible alert is requested, the radio is also
muted. Turn/hazard signal status is ignored;
the RCP state always requests the chime.
Blind Spot Alert Off
When the BSM system is turned off there will
be no visual or audible alerts from either the
BSM or RCP systems.
NOTE:
The BSM system will store the current oper-
ating mode when the vehicle is shut off. Each
time the vehicle is started the previously
stored mode will be recalled and used.
SAFETY

Forward Collision Warning (FCW) With
Mitigation
The Forward Collision Warning (FCW) with
Mitigation system provides the driver with
audible warnings, visual warnings (within the
instrument cluster display), 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 for-
ward looking sensors as well as the Electronic
Brake Controller (EBC), to calculate the prob-
ability of a forward collision. When the sys-
tem 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 lim-
ited level of active braking to help slow the
vehicle and mitigate the potential forward
collision. If the driver reacts to the warningsby 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 pro-
vide additional brake force as required.
If a Forward Collision Warning with Mitigation
event begins at a speed below 26 mph
(42 km/h), the system may provide the maxi-
mum or partial braking to mitigate the poten-
tial forward collision. If the Forward Collision
Warning with Mitigation event stops the ve-
hicle completely, the system will hold the
vehicle at a standstill for two seconds and
then release the brakes.
W
hen 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 igni-
tion cycle, the Active Braking portion of
FCW will be deactivated until the next igni-
tion 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 pre-
vent unnecessary warnings to the surround-
ings. If the vehicle enters 4WD Low Range
or ESC Full-Off Mode is active, the FCW
system will be automatically deactivated.
WARNING!
Forward Collision Warning (FCW) is not
intended to avoid a collision on its own,
nor can FCW detect every type of potential
collision. The driver has the responsibility
to avoid a collision by controlling the ve-
hicle via braking and steering. Failure to
follow this warning could lead to serious
injury or death.
101

FCW Braking Status And Sensitivity
The FCW Sensitivity and Active Braking sta-
tus are programmable through the Uconnect
System. Refer to “Uconnect Settings” in
“Multimedia” in the Owner’s Manual for fur-
ther information.
The default sensitivity of FCW is the “Me-
dium” 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 warn-
ings 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 "Medium" set-
ting. This provides the most reaction time to
avoid a possible collision.
Changing the FCW status to the “Near” set-
ting, 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 providesless reaction time than the “Far” and “Me-
dium” settings, which allows for a more dy-
namic driving experience.
NOTE:
• Changing the FCW status to “Only Warn-
ing” prevents the system from providing
limited active braking, or additional brake
support if the driver is not braking ad-
equately 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 NOT retain the last setting
selected by the driver after ignition shut
down. The system will reset to "Medium"
sensitivity and system status as “Warning &
Braking” when the vehicle is restarted.• FCW may not react to irrelevant objects
such as overhead objects, ground reflec-
tions, objects not in the path of the vehicle,
stationary objects that are far away, oncom-
ing 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 displays “ACC/FCW
Limited Functionality” or “ACC/FCW Limited
Functionality Clean Front Windshield” mo-
mentarily, there may be a condition that lim-
its 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.
