2014 JEEP GRAND CHEROKEE sensor

ADAPTIVE CRUISE CONTROL (ACC)
If your vehicle is equipped with adaptive
cruise control the controls operate ex-
actly the same as the normal (fixed
speed) cruise control with one difference.
You can set a specified distance you
would like to maintain between you and
the vehicle in front of you.
If the ACC sensor detects a vehicle
ahead, ACC will apply limited braking or
acceleration automatically to maintain a
preset following distance, while match-
ing the speed of the vehicle ahead.
If the sensor does not detect a vehicle
ahead of you, ACC will maintain a fixed
set speed.
ACC ON/OFF
• Push and release the Adaptive Cruise Control (ACC) ON/OFF button.
ACC READY will appear on the instrument cluster to indicate the ACC is on.
• Push and release the Adaptive Cruise Control (ACC) ON/OFF button a second time
to turn the system off.
Adaptive Cruise Control (ACC) Off will appear on the instrument cluster to indicate
the ACC is off.
Distance Setting (ACC Only)
The specified following distance for ACC can be set by varying the distance setting
between four bars (longest), three bars (long), two bars (medium) and one bar (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 increase the distance setting, press the Distance Setting—Increase button and
release. Each time the button is pressed, the distance setting increases by one bar
(longer).
• 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).

FORWARD COLLISION WARNING (FCW) WITH
MITIGATION
The Forward Collision Warning (FCW) system with mitigation provides the driver with
audible warnings, visual warnings within the EVIC, 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 forward looking sensors as well as the
Electronic Brake Controller (EBC), to calculate the probability of a forward collision.
When the system 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 limited level of active braking to help slow the vehicle and
mitigate the potential forward collision. If the driver reacts to the warnings by 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 provide
additional brake force as required.
Turning FCW ON Or OFF
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 when you are farther away and it applies
limited braking. This gives you the most reaction time to avoid a possible collision.
The forward collision button is on the switch panel that is located in the center of the
instrument panel.
•
To turn the FCW system OFF, press the forward collision button once (LED turns on).
• To turn the FCW system back ON, press the forward collision button again (LED
turns off).
Changing FCW Status
The FCW feature has two settings and can be changed within the Uconnect
®System
Screen:
• Far
• Near
NOTE:
The FCW and active braking settings can only be changed when the vehicle is in
PARK.

System Overview
This vehicle is equipped with a Diesel Exhaust Fluid (DEF) injection system and a
Selective Catalytic Reduction (SCR) catalyst to meet the emission requirements.
The DEF injection system consists of the following components:
• DEF tank
• DEF pump
• DEF injector
• Electronically-heated DEF lines• NOx sensors
• Temperature sensors
• SCR catalyst
The DEF injection system and SCR catalyst enable the achievement of diesel
emissions requirements; while maintaining outstanding fuel economy, drivability,
torque and power ratings.
NOTE:
• Your vehicle is equipped with a DEF injection system. You may occasionally hear
an audible clicking noise. This is normal operation.
• The DEF pump will run for a period of time after engine shutdown to purge the DEF
system. This is normal operation.
Adding Diesel Exhaust Fluid
The DEF gauge (located in the EVIC) will display the level of DEF remaining in the tank.
Completely fill the DEF tank through the diesel exhaust fluid fill location (located
behind the fuel door) at every maintenance interval or before if prompted by the
Electronic Vehicle Information Center (EVIC).
NOTE:
• The gauge may take up to five seconds
to update after adding a gallon or more
of Diesel Exhaust Fluid (DEF) to the
DEF tank. If you have a fault related to
the DEF system, the gauge may not
update to the new level. See your au-
thorized dealer for service.
• The DEF gauge may also not immedi-
ately update after a refill if the tem-
perature of the DEF fluid is below 12°F
(-11°C). The DEF line heater will pos-
sibly warm up the DEF fluid and allow
the gauge to update after a period of
run time. Under very cold conditions, it is possible that the gauge may not reflect
the new fill level for several drives.
