sensor JEEP GRAND CHEROKEE 2014 WK2 / 4.G User Guide

The BSM detection zone covers approximately one lane
on both sides of the vehicle (12 ft or 3.8 m). The zone
starts at the outside rear view mirror and extends ap-
proximately 23 ft (7 m) to the rear of the vehicle. The BSM
system monitors the detection zones on both sides of the
vehicle when the vehicle speed has reached approxi-
mately 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 de-
tection 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 equipment) extends beyond the side of your vehicle, this may result in the
BSM warning light remaining illuminated the entire
time the vehicle is in a forward gear.
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 (bum-
per 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 to sounding an
audible (chime) alert and reducing the radio volume.
Refer to “Modes Of Operation” for further information.The BSM system monitors the detection zone from three
different entry points (side, rear, front) while driving to
see if an alert is necessary. The BSM system will issue an
alert during these types of zone entries.

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, including reducing the radio volume.
WARNING!
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 back-
ing up. Failure to do so can result in serious injury or
death.

WARNING!
Electronic Speed Control can be dangerous where the
system cannot maintain a constant speed. Your ve-
hicle could go too fast for the conditions, and you
could lose control and have an accident. Do not use
Electronic Speed Control in heavy traffic or on roads
that are winding, icy, snow-covered or slippery.
ADAPTIVE CRUISE CONTROL (ACC) — IF
EQUIPPED
Adaptive Cruise Control (ACC) increases the driving
convenience provided by cruise control while traveling
on highways and major roadways. However, it is not a
safety system and not designed to prevent collisions.
ACC will allow you to keep cruise control engaged in
light to moderate traffic conditions without the constantneed to reset your cruise control. ACC utilizes a radar
sensor and a forward facing camera designed to detect a
vehicle directly ahead of you.
NOTE:
•
If the sensor does not detect a vehicle ahead of you,
ACC will maintain a fixed set speed.
• If the ACC sensor detects a vehicle ahead, ACC will
apply limited braking or acceleration (not to exceed
the original set speed) automatically to maintain a
preset following distance, while matching the speed of
the vehicle ahead.

UNDERSTANDING THE FEATURES OF YOUR VEHICLE 187

To decrease the distance setting, press the Distance
Setting — Decrease button and release. Each time the
button is pressed, the distance setting decreases by one
bar (shorter).
If there is no vehicle ahead, the vehicle will maintain the
set speed. If a slower moving vehicle is detected in the
same lane, the EVIC displays the “Sensed Vehicle Indi-
cator” icon, and the system adjusts vehicle speed auto-
matically to maintain the distance setting, regardless of
the set speed.
The vehicle will then maintain the set distance until:
•The vehicle ahead accelerates to a speed above the set
speed.
• The vehicle ahead moves out of your lane or view of
the sensor. •
The distance setting is changed.
• The system disengages. (Refer to the information on
ACC Activation).
The maximum braking applied by ACC is limited; how-
ever, the driver can always apply the brakes manually, if
necessary.
NOTE: The brake lights will illuminate whenever the
ACC system applies the brakes.
A Proximity Warning will alert the driver if ACC predicts
that its maximum braking level is not sufficient to
maintain the set distance. If this occurs, a visual alert
“BRAKE” will flash in the EVIC and a chime will sound
while ACC continues to apply its maximum braking
capacity.

Display Warnings And Maintenance
“Wipe Front Radar Sensor In Front Of Vehicle”
Warning
The “ACC/FCW Unavailable Wipe Front Radar Sensor”
warning will display and also a chime will indicate when
conditions temporarily limit system performance.
This most often occurs at times of poor visibility, such as
in snow or heavy rain. The ACC system may also become
temporarily blinded due to obstructions, such as mud,
dirt or ice. In these cases, the EVIC will display “ACC/
FCW Unavailable Wipe Front Radar Sensor” and the
system will deactivate.
The “ACC/FCW Unavailable Wipe Front Radar Sensor”
message can sometimes be displayed while driving in
highly reflective areas (i.e. tunnels with reflective tiles, or
ice and snow). The ACC system will recover after thevehicle has left these areas. Under rare conditions, when
the radar is not tracking any vehicles or objects in its path
this warning may temporarily occur.
NOTE:
If the “ACC/FCW Unavailable Wipe Front Radar
Sensor” warning is active Normal (Fixed Speed) Cruise
Control is still available. For additional information refer
to “Normal (Fixed Speed) Cruise Control Mode” in this
section.
If weather conditions are not a factor, the driver should
examine the sensor. It may require cleaning or removal of
an obstruction. The sensor is located in the center of the
vehicle behind the lower grille.
To keep the ACC System operating properly, it is impor-
tant to note the following maintenance items:
• Always keep the sensor clean. Carefully wipe the
sensor lens with a soft cloth. Be cautious not to damage
the sensor lens.

UNDERSTANDING THE FEATURES OF YOUR VEHICLE 203

•Do not remove any screws from the sensor. Doing so
could cause an ACC system malfunction or failure and
require a sensor realignment.
• If the sensor or front end of the vehicle is damaged due
to a collision, see your authorized dealer for service.
• Do not attach or install any accessories near the sensor,
including transparent material or aftermarket grilles.
Doing so could cause an ACC system failure or
malfunction.
When the condition that deactivated the system is no
longer present, the system will return to the “Adaptive
Cruise Control Off” state and will resume function by
simply reactivating it. NOTE:
•
If the “ACC/FCW Unavailable Wipe Front Radar
Sensor” message occurs frequently (e.g. more than
once on every trip) without any snow, rain, mud, or
other obstruction, have the radar sensor realigned at
your authorized dealer.
• Installing a snow plow, front-end protector, an after-
market grille or modifying the grille is not recom-
mended. Doing so may block the sensor and inhibit
ACC/FCW operation.
“Clean Front Windshield” Warning
The “ACC/FCW Limited Functionality Clean Front
Windshield” warning will display and also a chime will
indicate when conditions temporarily limit system per-
formance. This most often occurs at times of poor visibil-
ity, such as in snow or heavy rain and fog. The ACC
system may also become temporarily blinded due to
