turn signal JEEP GRAND CHEROKEE 2021 Owner handbook (in English)

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
100

injuries happen when people are thrown from
the vehicle. Seat belts reduce the possibility
of ejection and the risk of injury caused by
striking the inside of the vehicle. Everyone in
a motor vehicle should be belted at all times.
Enhanced Seat Belt Use Reminder System
(BeltAlert)
Driver and Passenger BeltAlert (if equipped)
BeltAlert is a feature intended to remind
the driver and outboard front seat passenger
(if equipped with outboard front passenger
seat BeltAlert) to buckle their seat belts. The
Belt Alert feature is active whenever the igni-
tion switch is in the START or ON/RUN posi-
tion.
Initial Indication
If the driver is unbuckled when the ignition
switch is first in the START or ON/RUN posi-
tion, a chime will signal for a few seconds. If
the driver or outboard front seat passenger (if
equipped with outboard front passenger seat
BeltAlert) is unbuckled when the ignition
switch is first in the START or ON/RUN posi-
tion the Seat Belt Reminder Light will turn on
and remain on until both outboard front seatbelts are buckled. The outboard front passen-
ger seat BeltAlert is not active when an out-
board front passenger seat is unoccupied.
BeltAlert Warning Sequence
The BeltAlert warning sequence is activated
when the vehicle is moving above a specified
vehicle speed range and the driver or out-
board front seat passenger is unbuckled (if
equipped with outboard front passenger seat
BeltAlert) (the outboard front passenger seat
BeltAlert is not active when the outboard
front passenger seat is unoccupied). The
BeltAlert warning sequence starts by blinking
the Seat Belt Reminder Light and sounding
an intermittent chime. Once the BeltAlert
warning sequence has completed, the Seat
Belt Reminder Light will remain on until the
seat belts are buckled. The BeltAlert warning
sequence may repeat based on vehicle speed
until the driver and occupied outboard front
seat passenger seat belts are buckled. The
driver should instruct all occupants to buckle
their seat belts.
Change of Status
If the driver or outboard front seat passenger
(if equipped with outboard front passengerseat BeltAlert) unbuckles their seat belt while
the vehicle is traveling, the BeltAlert warning
sequence will begin until the seat belts are
buckled again.
The outboard front passenger seat BeltAlert
is not active when the outboard front passen-
ger seat is unoccupied. BeltAlert may be
triggered when an animal or other items are
placed on the outboard front passenger seat
or when the seat is folded flat (if equipped). It
is recommended that pets be restrained in
the rear seat (if equipped) in pet harnesses or
pet carriers that are secured by seat belts,
and cargo is properly stowed.
BeltAlert can be activated or deactivated by
an authorized dealer. FCA does not recom-
mend deactivating BeltAlert.
NOTE:
If BeltAlert has been deactivated and the
driver or outboard front seat passenger (if
equipped with outboard front passenger seat
BeltAlert) is unbuckled the Seat Belt Re-
minder Light will turn on and remain on until
the driver and outboard front seat passenger
seat belts are buckled.

WARNING!
• NEVER place any objects under the floor
mat (e.g., towels, keys, etc.). These ob-
jects could change the position of the
floor mat and may cause interference
with the accelerator, brake, or clutch
pedals.
• If the vehicle carpet has been removed
and re-installed, always properly attach
carpet to the floor and check the floor
mat fasteners are secure to the vehicle
carpet. Fully depress each pedal to
check for interference with the accelera-
tor, brake, or clutch pedals then re-
install the floor mats.
• It is recommended to only use mild soap
and water to clean your floor mats. After
cleaning, always check your floor mat
has been properly installed and is se-
cured to your vehicle using the floor mat
fasteners by lightly pulling mat.
Periodic Safety Checks You Should Make
Outside The Vehicle
Tires
Examine tires for excessive tread wear and
uneven wear patterns. Check for stones,
nails, glass, or other objects lodged in the
tread or sidewall. Inspect the tread for cuts
and cracks. Inspect sidewalls for cuts,
cracks, and bulges. Check the wheel nuts for
tightness. Check the tires (including spare)
for proper cold inflation pressure.
Lights
Have someone observe the operation of brake
lights and exterior lights while you work the
controls. Check turn signal and high beam
indicator lights on the instrument panel.
Door Latches
Check for proper closing, latching, and locking.
Fluid Leaks
Check area under the vehicle after overnight
parking for fuel, coolant, oil, or other fluid
leaks. Also, if gasoline fumes are detected or
if fuel, or brake fluid leaks are suspected. The
cause should be located and corrected
immediately.
WARNING!
To prevent SERIOUS INJURY or DEATH
when using “Track-Use” parts and equip-
ment:
• NEVER use any “Track-Use” equipment
on public roads. FCA does not authorize
the use of “Track-Use” equipment on
public roads.
• The intended use of “Track-Use” parts is
for race vehicles on race tracks. To help
ensure the safety of the race driver, en-
gineers should supervise the installation
of “Track-Use” parts.
• FCA does not authorize the installation
or use of any part noted as “Track-Use”
on any new vehicle prior to its first retail
sale.
143

NOTE:
• The driver is always responsible for control-
ling the vehicle, responsible for any sur-
rounding objects, and must intervene as
required.
• The system is provided to assist the driver
and not to substitute the driver.
• During a semi-automatic maneuver, if the
driver touches the steering wheel after be-
ing instructed to remove their hands from
the steering wheel, the system will cancel,
and the driver will be required to manually
complete the parking maneuver.
• The system may not work in all conditions
(e.g. environmental conditions such as
heavy rain, snow, etc., or if searching for a
parking space that has surfaces that will
absorb the ultrasonic sensor waves).
•N
ew vehicles from the dealership must have
at least 30 miles (48 km) accumulated be-
fore the ParkSense Active Park Assist system
is fully calibrated and performs accurately.
This is due to the system’s dynamic vehicle
calibration to improve the performance of the
feature. The system will also continuouslyperform the dynamic vehicle calibration to
account for differences such as over or under
inflated tires and new tires.
Enabling And Disabling The ParkSense
Active Park Assist System

information.
LANESENSE — IF EQUIPPED
LaneSense Operation
The LaneSense system is operational at
speeds above 37 mph (60 km/h) and below
112 mph (180 km/h). The LaneSense system
uses a forward looking camera to detect lane
markings and measure vehicle position
within the lane boundaries.
181

When both lane markings are detected and
the driver unintentionally drifts out of the
lane (no turn signal applied), the LaneSense
system provides a haptic warning in the form
of torque applied to the steering wheel to
prompt the driver to remain within the lane
boundaries. If the driver continues to unin-
tentionally drift out of the lane, the Lane-
Sense system provides a visual warning
through the instrument cluster display to
prompt the driver to remain within the lane
boundaries.
The driver may manually override the haptic
warning by applying torque into the steering
wheel at any time.
When only a single lane marking is detected
and the driver unintentionally drifts across
the lane marking (no turn signal applied), the
LaneSense system provides visual warnings
through the instrument cluster display to
prompt the driver to remain within the lane.
When only a single lane marking is detected,
a haptic (torque) warning will not be
provided.NOTE:
When operating conditions have been met,
the LaneSense system will monitor if the
driver’s hands are on the steering wheel and
provides an audible warning to the driver
when the driver’s hands are not detected on
the steering wheel. The system will cancel if
the driver does not return their hands to the
wheel.
Turning LaneSense On Or Off
The default status of LaneSense is off. The
LED in LaneSense button will be illuminated
while the system is deactivated.
The LaneSense button is located
on the switch panel below the
Uconnect display.
To turn the LaneSense system
on, push the LaneSense button (LED turns
off). A “LaneSense On” message is shown in
the instrument cluster display.
To turn the LaneSense system off, push the
LaneSense button once (LED turns on).NOTE:
The LaneSense system will retain the last
system state on or off from the last ignition
cycle when the ignition is changed to the
ON/RUN position.
LaneSense Warning Message
The LaneSense system will indicate the cur-
rent lane drift condition through the instru-
ment cluster display.
Premium Instrument Cluster Display
When the LaneSense system is on; the lane
lines are gray when both of the lane bound-
aries have not been detected and the Lane-
Sense telltale
is solid white.
Left Lane Departure — Only Left Lane Detected
• When the LaneSense system is on, the
LaneSense telltale
is solid white when
only the left lane marking has been de-
tected and the system is ready to provide
visual warnings in the instrument cluster
display if an unintentional lane departure
occurs.
STARTING AND OPERATING
182

• When the LaneSense system senses the
lane has been approached and is in a lane
departure situation, the left thick lane line
flashes yellow (on/off), the left thin line
remains solid yellow and the LaneSense
telltale
changes from solid white to
flashing yellow.
NOTE:
The LaneSense system operates with the
similar behavior for a right lane departure
when only the right lane marking has been
detected.
Left Lane Departure — Both Lanes Detected
• When the LaneSense system is on, the lane
lines turn from gray to white to indicate that
both of the lane markings have been de-
tected. The LaneSense telltale
is solid
green when both lane markings have been
detected and the system is on to provide
visual warnings in the instrument cluster
display and a torque warning in the steering
wheel if an unintentional lane departure
occurs.• When the LaneSense system senses a lane
drift situation, the left thick lane line and
left thin line turn solid yellow. The Lane-
Sense telltale
changes from solid green
to solid yellow. At this time torque is ap-
plied to the steering wheel in the opposite
direction of the lane boundary.
For example: If approaching the left side of
the lane the steering wheel will turn to the
right.
• When the LaneSense system senses the
lane has been approached and is in a lane
departure situation, the left thick lane line
flashes yellow (on/off) and the left thin line
remains solid yellow. The LaneSense tell-
tale
changes from solid yellow to flash-
ing yellow. At this time torque is applied to
the steering wheel in the opposite direction
of the lane boundary.
For example: If approaching the left side of
the lane the steering wheel will turn to the
right.
NOTE:
The LaneSense system operates with the
similar behavior for a right lane departure.
Changing LaneSense Status
The LaneSense system has settings to adjust
the intensity of the torque warning and the
warning zone sensitivity (early/late) that you
can configure through the Uconnect system
screen. Refer to “Uconnect Settings” in
“Multimedia” in your Owner’s Manual for
further information.
NOTE:
• When enabled the system operates above
37 mph (60 km/h) and below 112 mph
(180 km/h).
• Use of the turn signal suppresses the warn-
ings.
• The system will not apply torque to the
steering wheel whenever a safety system
engages (anti-lock brakes, traction control
system, electronic stability control, forward
collision warning, etc.).
