2017 JEEP GRAND CHEROKEE warning

should be used for most driving conditions.
Alternate ESC modes should only be used for
specific reasons as noted in the following
paragraphs.
Partial Off
The “Partial Off” mode is intended for times
when a more spirited driving experience is
desired. This mode may modify TCS and ESC
thresholds for activation, which allows for
more wheel spin than normally allowed. This
mode may be useful if the vehicle becomes
stuck.
To enter the “Partial Off” mode, momentarily
push the “ESC Off” switch and the “ESC Off
Indicator Light” will illuminate. To turn the
ESC on again, momentarily push the “ESC
Off” switch and the “ESC Off Indicator Light”
will turn off.
NOTE:
For vehicles with multiple partial ESC modes
a momentary button push will toggle the ESC
mode. Multiple momentary button pushed
may be required to return to ESC On.NOTE:
• When in “Partial Off” mode, the TCS func-
tionality of ESC, (except for the limited
slip feature described in the TCS section),
has been disabled and the “ESC Off Indi-
cator Light” will be illuminated. When in
“Partial Off” mode, the engine power re-
duction feature of TCS is disabled, and the
enhanced vehicle stability offered by the
ESC system is reduced.
• Trailer Sway control (TSC) is disabled when the ESC system is in the “Partial
Off” mode.
Full Off – If Equipped
This mode is intended for off-highway or
off-road use only and should not be used on
any public roadways. In this mode, TCS and
ESC features are turned OFF. To enter the
“Full Off” mode, push and hold the “ESC
Off” switch for five seconds while the vehicle
is stopped with the engine running. After five
seconds, a chime will sound, the “ESC Off
Indicator Light” will illuminate, and the
“ESC OFF” message will display in the in-
strument cluster. To turn ESC ON again,
momentarily push the “ESC Off” switch. NOTE:
System may switch from ESC “Full Off” to
“Partial Off” mode when vehicle exceeds a
predetermined speed. When the vehicle
speed slows below the predetermined speed
the system will return to ESC “Full Off”.
“Full Off” can only be achieved in Track
Mode if so equipped.
ESC modes may also be affected by drive
modes if so equipped.
WARNING!
• In the ESC “Full Off” mode, the engine
torque reduction and stability features
are disabled. Therefore, enhanced ve-
hicle stability offered by the ESC system
is unavailable. In an emergency evasive
maneuver, the ESC system will not en-
gage to assist in maintaining stability.
“ESC Off” mode is intended for off-
highway or off-road use only.
• With the ESC switched off, the en-
hanced vehicle stability offered by ESC
is unavailable. In an emergency evasive
maneuver, the ESC system will not en-

WARNING!
gage to assist in maintaining stability.
“Full Off” mode is only intended for
off-highway or off-road use.
• The Electronic Stability Control (ESC)
cannot prevent the natural laws of phys-
ics from acting on the vehicle, nor can it
increase the traction afforded by prevail-
ing road conditions. ESC cannot prevent
all accidents, including those resulting
from excessive speed in turns, driving on
very slippery surfaces, or hydroplaning.
ESC also cannot prevent collisions.
ESC Activation/Malfunction Indicator Light
and ESC OFF Indicator Light
The “ESC Activation/
Malfunction Indicator
Light” in the instrument
cluster will come on when
the ignition is turned to
the ON mode. It should go
out with the engine run-
ning. If the “ESC Activation/Malfunction In- dicator Light” comes on continuously with
the engine running, a malfunction has been
detected in the ESC system. If this light
remains on after several ignition cycles, and
the vehicle has been driven several miles
(kilometers) at speeds greater than 30 mph
(48 km/h), see your authorized dealer as soon
as possible to have the problem diagnosed
and corrected.
The “ESC Activation/Malfunction Indicator
Light” (located in the instrument cluster)
starts to flash as soon as the tires lose trac-
tion and the ESC system becomes active. The
“ESC Activation/Malfunction Indicator
Light” also flashes when TCS is active. If the
“ESC Activation/Malfunction Indicator
Light” begins to flash during acceleration,
ease up on the accelerator and apply as little
throttle as possible. Be sure to adapt your
speed and driving to the prevailing road con-
ditions.
NOTE:
• The “ESC Activation/Malfunction Indica-
tor Light” and the “ESC OFF Indicator
Light” come on momentarily each time
the ignition is turned ON. • Each time the ignition is turned ON, the
ESC system will be on even if it was turned
off previously.
• The ESC system will make buzzing or clicking sounds when it is active. This is
normal; the sounds will stop when ESC
becomes inactive following the maneuver
that caused the ESC activation.
The “ESC OFF Indicator
Light” indicates the cus-
tomer has elected to have
the Electronic Stability
Control (ESC) in a re-
duced mode.
Electronic Roll Mitigation (ERM)
This system anticipates the potential for
wheel lift by monitoring the driver’s steering
wheel input and the speed of the vehicle.
When ERM determines that the rate of
change of the steering wheel angle and vehi-
cle’s speed are sufficient to potentially cause
wheel lift, it then applies the appropriate
brake and may also reduce engine power to
lessen the chance that wheel lift will occur.
ERM can only reduce the chance of wheel lift

occurring during severe or evasive driving
maneuvers; it cannot prevent wheel lift due to
other factors, such as road conditions, leav-
ing the roadway, or striking objects or other
vehicles.
NOTE:
ERM is disabled anytime the ESC is in “Full
Off” mode (if equipped). Refer to “Electronic
Stability Control (ESC)” in this section for a
complete explanation of the available ESC
modes.
WARNING!
Many factors, such as vehicle loading,
road conditions and driving conditions,
influence the chance that wheel lift or
rollover may occur. ERM cannot prevent all
wheel lift or roll overs, especially those
that involve leaving the roadway or striking
objects or other vehicles. The capabilities
of an ERM-equipped vehicle must never
be exploited in a reckless or dangerous
manner which could jeopardize the user's
safety or the safety of others.
Trailer Sway Control (TSC)
TSC uses sensors in the vehicle to recognize
an excessively swaying trailer and will take
the appropriate actions to attempt to stop the
sway. TSC will become active automatically
once an excessively swaying trailer is recog-
nized. Note that TSC cannot stop all trailers
from swaying. Always use caution when tow-
ing a trailer and follow the trailer tongue
weight recommendations. Refer to “Trailer
Towing” in “Starting And Operating” for fur-
ther information. When TSC is functioning,
the “ESC Activation/Malfunction Indicator
Light” will flash, the engine power may be
reduced and you may feel the brakes being
applied to individual wheels to attempt to
stop the trailer from swaying. TSC is disabled
when the ESC system is in the “Partial Off” or
“Full Off” modes.
WARNING!
If TSC activates while driving, slow the
vehicle down, stop at the nearest safe
location, and adjust the trailer load to
eliminate trailer sway.
Ready Alert Braking (RAB)
Ready Alert Braking may reduce the time
required to reach full braking during emer-
gency braking situations. It anticipates when
an emergency braking situation may occur by
monitoring how fast the throttle is released by
the driver. The EBC will prepare the brake
system for a panic stop.
Rain Brake Support (RBS)
Rain Brake Support may improve braking
performance in wet conditions. It will periodi-
cally apply a small amount of brake pressure
to remove any water buildup on the front
brake rotors. It functions when the wind-
shield wipers are in LO or HI speed. When
Rain Brake Support is active, there is no
notification to the driver and no driver inter-
action is required.
Dynamic Steering Torque (DST)
Dynamic Steering Torque is a feature of the
ESC and EPS modules that provides torque at
the steering wheel for certain driving condi-
tions in which the ESC module is detecting
vehicle instability. The torque that the steer-
ing wheel receives is only meant to help the

NOTE:
During HDC the +/- shifter input is used for
HDC target speed selection but will not affect
the gear chosen by the transmission. When
actively controlling HDC the transmission 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 withthrottle 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 which offer
feedback to the driver about the state HDC is
in.
• The cluster icon and switch lamp will illuminate 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
enable 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.
101

• Vehicle is shifted to PARK.
Disabling SSC
SSC will deactivate and be disabled if any of
the following conditions occur:
• The driver pushes the SSC switch.
• The driveline is shifted out of 4WD LowRange.
• 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) (SSC exits immediately).
Feedback To The Driver:
The instrument cluster has an SSC icon and
the SSC switch has an LED which offer feed-
back to the driver about the state SSC is in.
• The cluster icon and switch lamp will illuminate and remain on solid when SSC
is enabled or activated. This is the normal
operating condition for SSC. • The cluster icon and switch lamp will flash
for several seconds then extinguish when
the driver pushes the SSC switch but en-
able conditions are not met.
• The cluster icon and switch lamp will flash for several seconds then extinguish when
SSC disables due to excess speed.
• The cluster icon and switch lamp will flash then extinguish when SSC deactivates due
to overheated brakes.
WARNING!
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
The Blind Spot Monitoring (BSM) system
uses two radar-based sensors, located inside
the rear bumper fascia, to detect Highway
licensable vehicles (automobiles, trucks, mo-
torcycles etc.) that enter the blind spot zones
from the rear/front/side of the vehicle.
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 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.
103

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 and enters
stand by mode when the vehicle is in PARK.
The BSM warning light, located in the out-
side mirrors, will illuminate if a vehicle
moves into a blind spot zone.The BSM system can also be configured to
sound an audible (chime) alert and mute the
radio to notify you of objects that have en-
tered the detection zones.
Rear Cross Path (RCP)
The Rear Cross Path (RCP) feature is in-
tended to aid the driver when backing out of
parking spaces where the 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 de-
tected, will alert the driver. 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.
Refer to “Blind Spot Monitoring” in “Safety”
in the Owner's Manual at
www.jeep.com/en/owners/manuals/ for more
information.
Modes Of Operation
Three selectable modes of operation are
available in the Uconnect System. Refer to
“Uconnect Settings/Customer Programmable
Features” in “Multimedia” for further infor-
mation.
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
Rear Detection Zones
Blind Spot Warning Light

104

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. Wheneveran 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.
Forward Collision Warning (FCW)
The Forward Collision Warning (FCW) system
provides the driver with audible and visual
warnings within the instrument cluster dis-
play to warn the driver when it detects a
potential frontal collision. The warnings 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.
Turning FCW ON Or OFF
The forward collision button is located in the
Uconnect display in the controls settings.
• To turn the FCW system OFF, press the
forward collision button once to turn the
system OFF.
• To turn the FCW system back ON, press the forward collision button again to turn
the system ON.
NOTE:
• The default status of FCW is “On”, this allows the system to warn you of a possible
collision with the vehicle in front of you.
105

• Changing the FCW status to “Off” pre-vents the system from warning you of a
possible collision with the vehicle in front
of you. If FCW is set to “Off”, “FCW OFF”
will appear in the instrument cluster
display.
Changing FCW Status
The FCW feature has three settings and can
be changed within the Uconnect System
Screen:
• Far
• Medium
• Near
Far
The far setting provides warnings for poten-
tial collisions more distant in front of the
vehicle, allowing the driver to have the most
reaction time to avoid a collision.
More cautious drivers that do not mind fre-
quent warnings may prefer this setting.
NOTE:
This setting gives you the most reaction time. Medium
The default status of FCW is the “Medium”
setting and the Active Braking is in the “On”
setting. 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.
Near
Changing the FCW status to the “Near” set-
ting, allows the system to warn you of a
potential frontal collision when you are much
closer.
This setting provides less reaction time than
the “Far” setting, which allows for a more
dynamic driving experience.
More dynamic or aggressive drivers that want
to avoid frequent warnings may prefer this
setting.
NOTE:
Changing the Active Braking status to “Off”
prevents the system from providing autono-
mous braking, or additional brake support if
the driver is not braking adequately in the
event of a potential frontal collision. Active
braking can be turned “Off” in the Uconnect
controls settings.
Refer to your Owner's Manual at
www.jeep.com/en/owners/manuals/ for fur-
ther details.
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.
