2013 JEEP GRAND CHEROKEE evic system

To Resume SpeedPress the RES+button and release. Then
remove your foot from the accelerator pedal.
The EVIC will display the last set speed.
NOTE:
You can resume ACC from a minimum of
18 mph (30 km/h).
WARNING!
The Resume function should only be used if
traffic and road conditions permit. Resuming
a set speed that is too high or too low for
prevailing traffic and road conditions could
cause the vehicle to accelerate or decelerate
too sharply for safe operation. Failure to
follow these warnings can result in a collision
and death or serious personal injury.
To Vary The Speed SettingWhile ACC is set, you can increase the set
speed by pressing and holding the RES +
button. If the button is continually pressed, the
set speed will continue to increase in 5 mph
(10 km/h) increments until the button is re-
leased. The increase in set speed is reflected in
the EVIC display.
Pressing the RES +button once will result in a
1 mph (1 km/h) increase in set speed. Each
subsequent tap of the button results in an
increase of 1 mph (1 km/h).
While ACC is set, the set speed can be de-
creased by pressing and holding the SET -
button. If the button is continually pressed, the
set speed will continue to decrease in 5 mph
(10 km/h) increments until the button is re-
leased. The decrease in set speed is reflected
in the EVIC display.
Pressing the SET -button once will result in a
1 mph (1 km/h) decrease in set speed. Each
subsequent tap of the button results in a de-
crease of 1 mph (1 km/h). NOTE:
•
When you use the SET - button to decel-
erate, if the engine’s braking power does
not slow the vehicle sufficiently to reach
the set speed, the brake system will auto-
matically slow the vehicle.
• The ACC system can only apply a maxi-
mum of 25% of the vehicle’s braking ca-
pability and will not bring the vehicle to a
complete stop.
•
The ACC system maintains set speed when
driving up hill and down hill. However, a
slight speed change on moderate hills is
normal. In addition, downshifting may oc-
cur while climbing uphill or descending
downhill. This is normal operation and nec-
essary to maintain set speed.

Setting The Following Distance In ACCThe specified following distance for ACC can be
set by varying the distance setting between
3 (long), 2 (medium), and 1 (short). Using this
distance setting and the vehicle speed, ACC
calculates and sets the distance to the vehicle
ahead. This distance setting displays in the
EVIC.To change the distance setting, press the Dis-
tance button and release. Each time the button
is pressed, the distance setting adjusts between
long, medium, and short.
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 Indicator” icon,
and the system adjusts vehicle speed automati-
cally to maintain the distance setting, regard-
less 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 vehicle ahead slows to a speed below
15 mph (24 km/h) and the system automati-
cally disengages itself.
• The distance setting is changed.
• The system disengages. (Refer to the infor-
mation on ACC Activation).

The maximum braking applied by ACC is lim-
ited; however, 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 contin-
ues to apply its maximum braking capacity.
When this occurs, you should immediately ap-
ply the brakes as needed to maintain a safe
distance from the vehicle ahead.
The ACC Systems provides Overtake Aid when
passing on the left hand side only. When driving
with ACC engaged and following a Target ve-
hicle, the system will provide an additional
acceleration based on your current speed. The
acceleration is triggered by indicating a left turn
signal.
Adaptive Cruise Control (ACC) MenuThe EVIC displays the current ACC system
settings. The EVIC is located in the upper part
of the instrument cluster between the speedom-
eter and the tachometer. The information it
displays depends on ACC system status.
Adaptive Cruise Control Off
•When ACC is deactivated, the display will
read “Adaptive Cruise Control Off.” Adaptive Cruise Control Ready
•
When ACC is activated but the vehicle speed
setting has not been selected, the display will
read “Adaptive Cruise Control Ready.”
ACC SET
• When ACC is set, the set speed will display.
• The set speed will continue to display in
place of the odometer reading when chang-
ing the EVIC display while ACC is set.

The ACC screen will display once again if any
ACC activity occurs, which may include any of
the following:
•Set Speed Change
• Distance Setting Change
• System Cancel
• Driver Override
• System Off
• ACC Proximity Warning
• ACC Unavailable Warning
• The EVIC will return to the last display se-
lected after five seconds of no ACC display
activity.
Display Warnings And Maintenance
“Clean Radar Sensor In Front Of Vehicle”
Warning
The ACC “Clean Radar Sensor In Front Of Ve-
hicle” warning will display when conditions tem-
porarily 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 “Clean Radar Sensor In Front Of Vehicle”
and the system will deactivate.
The “Clean Radar Sensor In Front Of Vehicle”
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 the vehicle 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 “Clean Radar Sensor In Front Of
Vehicle” 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 important 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.
• Do not remove any screws from the sensor.
Doing so could cause an ACC system mal-
function or failure and require a sensor
realignment.
• If the sensor is damaged due to a collision,
see your authorized dealer for service.

ACC Unavailable Warning
If the system turns off, and the EVIC displays
“ACC/FCW Unavailable, Vehicle System Error”,
there may be a temporary malfunction that
limits ACC functionality. Although the vehicle is
still drivable under normal conditions, ACC will
be temporarily unavailable. If this occurs, try
activating ACC again later, following a key
cycle. If the problem persists, see your autho-
rized dealer.
Service ACC Warning
If the system turns off, and the EVIC displays
“ACC/FCW Unavailable Service Radar Sen-
sor”, it indicates there is an internal system fault.
Although the vehicle is still drivable under nor-
mal conditions, have the system checked by an
authorized dealer.
Precautions While Driving With ACCIn certain driving situations, ACC may have
detection issues. In these cases, ACC may
brake late or unexpectedly. The driver needs to
stay alert and may need to intervene.Adding A Trailer Hitch
The weight of a trailer/hitch may affect the
performance of ACC. If there is a noticeable
change in performance following the installation
of a trailer/hitch, or if the ACC performance does
not return to normal after removing the trailer/
hitch see your authorized dealer.
Offset Driving
ACC may not detect a vehicle in the same lane
that is offset from your direct line of travel, or a
vehicle merging in from a side lane. There may
not be sufficient distance to the vehicle ahead.
The offset vehicle may move in and out of the
line of travel, which can cause your vehicle to
brake or accelerate unexpectedly.
Turns And Bends
When driving on a curve with ACC engaged, the
system may decrease the vehicle speed and
acceleration for stability reasons, with no target
vehicle detected. Once the vehicle is out of the
curve the system will resume your original Set
Speed. This is a part of normal ACC system
functionality.
NOTE:
On tight turns ACC performance may be
limited.
128

Stationary Objects And Vehicles
ACC does not react to stationary objects and
stationary vehicles. For example, ACC will not
react in situations where the vehicle you are
following exits your lane and the vehicle ahead
is stopped in your lane. Always be attentive and
ready to apply the brakes if necessary.General Information

Normal (Fixed Speed) Cruise
Control Mode
In addition to Adaptive Cruise Control mode, a
normal (fixed speed) Cruise Control mode is
available for cruising at fixed speeds. The nor-
mal Cruise Control mode is designed to main-
tain a set cruising speed without requiring the
driver to operate the accelerator. Cruise Control
can only be operated if the vehicle speed is
above 20 mph (32 km/h).
To change between the different cruise modes,
press the MODE button when the system is in
either the OFF, READY or SET state. Pressing
of the MODE button in any state will result in
changing to the new Mode in the OFF state.
WARNING!
In the normal Cruise Control mode, the sys-
tem will not react to vehicles ahead. In
addition, the proximity warning does not ac-
tivate and no alarm will sound even if you are
too close to the vehicle ahead since neither
the presence of the vehicle ahead nor the
vehicle-to-vehicle distance is detected. Be
sure to maintain a safe distance between
your vehicle and the vehicle ahead. Always
be aware which mode is selected.
To Set A Desired Speed
When the vehicle reaches the speed desired,
press the SET -button and release. The EVIC
will display the set speed.
NOTE:
You must observe the display when setting
or changing speed, not the speedometer.
130

To Vary The Speed Setting
There are two ways to change the set speed:
•
Use the accelerator pedal to adjust the vehicle
to the desired speed and press the SET-
button.
•Tap the RES +or SET -button to increase or
decrease the set speed in 1 mph (1.6 km/h)
increments respectively. Hold the RES +or
SET -button for 5 mph (8 km/h) increments.
To Cancel
The system will disable normal Cruise Control
without erasing the memory if:
• You softly tap or depress the brake pedal.
• You press the CANCEL button.
• The Electronic Stability Control/Traction Con-
trol System (ESC/TCS) activates.
To Resume
Press the RES +button and then remove your
foot from the accelerator pedal. The EVIC will
display the last set speed. To Turn Off
The system will turn off and erase the set speed
in memory if:
•
You push the Normal Fixed Speed ON/OFF
button.
• You turn off the ignition.
• You engage Four-Wheel Drive Low.
Forward Collision Warning — If
Equipped
The Forward Collision Warning (FCW) system
provides the driver with audible and visual
warnings (within the EVIC) when it detects a
potential frontal collision. The warnings are in-
tended to provide the driver with enough time to
react and avoid the potential collision.
FCW monitors the information from the forward
looking sensor as well as the Electronic Brake
Controller (EBC), wheel speed sensors, i.e., to
calculate a probable rear-end collision. When the
system determines that a rear-end collision is
probable a warning message (both audible and
visual) will be displayed on the EVIC. 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
10 mph (16 km/h).
• When entering or driving in a curve, the
FCW alerts may be triggered on objects
other than vehicles such as guard rails or
sign posts based on the course predic-
tion. This is expected and is a part of
normal FCW activation and functionality.
FCW Message
131

WARNING!
Forward Collision Warning (FCW) is not in-
tended to avoid a collision on its own, nor
can FCW detect every type of potential col-
lision. The driver has the responsibility to
avoid a collision by controlling the vehicle via
braking and steering. Failure to follow this
warning could lead to serious injury or death.
Changing FCW Status
The FCW feature can be set to far, set to near or
turned off in the Electronic Vehicle Information
Center (EVIC) refer to “Electronic Vehicle Infor-
mation Center (EVIC)” in “Understanding Your
Instrument Panel” for further information. The
FCW Status Off, Near or Far will be displayed in
the EVIC.
FCW settings can only be changed when the
vehicle is in PARK. The default status of FCW is the “Far” setting,
this allows the system to warn you of a possible
collision with the vehicle in front of you when
you are farther away. This gives you the most
reaction time.
Changing the FCW status to the “Near” setting,
allows the system to warn you of a possible
collision with the vehicle in front of you when
you are much closer. This setting provides less
reaction time than the “Far” setting, which al-
lows for a more dynamic driving experience.
