2015 JEEP GRAND CHEROKEE sensor

WARNING!
•Drivers must be careful when backing up even
when using ParkSense®. 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.
You are responsible for safety and must continue to
pay attention to your surroundings. Failure to do so
can result in serious injury or death.

WARNING!(Continued)
•Before using ParkSense®, it is strongly recom-
mended that the ball mount and hitch ball assem-
bly is disconnected from the vehicle when the
vehicle is not used for towing. Failure to do so can
result in injury or damage to vehicles or obstacles
because the hitch ball will be much closer to the
obstacle than the rear fascia when the loudspeaker
sounds the continuous tone. Also, the sensors
could detect the ball mount and hitch ball assem-
bly, depending on its size and shape, giving a false
indication that an obstacle is behind the vehicle.
242 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the system is not
operating properly. The TPMS malfunction indicator is
combined with the low tire pressure telltale. When the
system detects a malfunction, the telltale will flash for
approximately one minute and then remain continuously
illuminated. This sequence will continue upon subse-
quent vehicle start-ups as long as the malfunction exists.
When the malfunction indicator is illuminated, the sys-
tem may not be able to detect or signal low tire pressure
as intended. TPMS malfunctions may occur for a variety
of reasons, including the installation of replacement or
alternate tires or wheels on the vehicle that prevent the
TPMS from functioning properly. Always check the
TPMS malfunction telltale after replacing one or more
tires or wheels on your vehicle, to ensure that the
replacement or alternate tires and wheels allow the TPMS
to continue to function properly.
CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warning have been established for the tire size
equipped on your vehicle. Undesirable system opera-
tion or sensor damage may result when using re-
placement equipment that is not of the same size,
type, and/or style. Aftermarket wheels can cause
sensor damage. Do not use tire sealant from a can or
balance beads if your vehicle is equipped with a
TPMS, as damage to the sensors may result.
15. Driver Information Display (DID)
The odometer display shows the total distance the ve-
hicle has been driven.
U.S. Federal regulations require that upon transfer of
vehicle ownership, the seller certify to the purchaser the
correct mileage that the vehicle has been driven. If your

NOTE:Keep magnetic materials away from the top of the
instrument panel, such as iPod’s, Mobile Phones, Lap-
tops and Radar Detectors. This is where the compass
module is located, and it can cause interference with the
compass sensor, and it may give false readings.
•Perform Compass Calibration
Press the “Calibration” button on the touchscreen to
change this setting. This compass is self-calibrating,
which eliminates the need to manually reset the compass.
When the vehicle is new, the compass may appear erratic
until it is calibrated. You may also calibrate the compass
by pressing the “ON” button on the touchscreen and
completing one or more 360-degree turns (in an area free
from large metal or metallic objects). The compass will
now function normally.

arrow button on the touchscreen to return to the previous
menu. ParkSense® will retain its last known configura-
tion state through ignition cycles.
•Tilt Side Mirrors In Reverse
When this feature is selected, the exterior side view
mirrors will tilt downward when the ignition is in the
RUN position and the transmission shift lever is in the
REVERSE position. The mirrors will move back to their
previous position when the transmission is shifted out of
REVERSE. To make your selection, press the “Tilt Side
Mirrors In Reverse” button on the touchscreen, until a
check-mark appears next to setting, indicating that the
setting had been selected. Press the back arrow button on
the touchscreen to return to the previous menu.
•Blind Spot Alert
When this feature is selected, the Blind Spot Alert feature
Provides alerts, visual and/or audible, to indicate objects
in your blind spot. The Blind Spot Alert feature can be
activated in “Lights” mode. When this mode is selected,
the Blind Spot Monitor (BSM) system is activated and
will only show a visual alert in the exterior mirrors.
When “Lights & Chime” mode is activated, the Blind
Spot Monitor (BSM) will show a visual alert in the
exterior mirrors as well as an audible alert when the turn
signal is on. When “Off” is selected, the Blind Spot
Monitor (BSM) system is deactivated. To change the
Blind Spot Alert status, press the “Off,” “Lights” or
“Lights & Chime” button on the touchscreen. Then press
the back arrow button on the touchscreen.
NOTE:If your vehicle has experienced any damage in
the area where the sensor is located, even if the fascia is
not damaged, the sensor may have become misaligned.
Take your vehicle to an authorized dealer to verify sensor
alignment. Having a sensor that is misaligned will result
in the BSM not operating to specification.

WARNING!
Many factors, such as vehicle loading, road condi-
tions, and driving conditions, influence the chance
that wheel lift or rollover may occur. ERM cannot
prevent all wheel lift or rollovers, 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 reck-
less or dangerous manner, which could jeopardize
the user’s safety or the safety of others.
Electronic Stability Control (ESC)
This system enhances directional control and stability of
the vehicle under various driving conditions. ESC cor-
rects for oversteering or understeering of the vehicle by
applying the brake of the appropriate wheel to assist in
counteracting the oversteer or understeer condition. En-
gine power may also be reduced to help the vehicle
maintain the desired path.
ESC uses sensors in the vehicle to determine the vehicle
path intended by the driver and compares it to the actual
path of the vehicle. When the actual path does not match
the intended path, ESC applies the brake of the appro-
priate wheel to assist in counteracting the oversteer or
understeer condition.
•Oversteer - when the vehicle is turning more than
appropriate for the steering wheel position.
•Understeer - when the vehicle is turning less than
appropriate for the steering wheel position.
The “ESC Activation/Malfunction Indicator Light” lo-
cated in the instrument cluster will start to flash as soon
as the tires lose traction and the ESC system becomes
active. The “ESC Activation/Malfunction Indicator
Light” also flashes when the TCS is active. If the “ESC

WARNING!
•When in “Partial Off” mode, the TCS functionality
of ESC, (except for the limited slip feature de-
scribed in the TCS section), has been disabled and
the “ESC Off Indicator Light” will be illuminated.
When in “Partial Off” mode, the engine power
reduction feature of TCS is disabled, and the
enhanced vehicle stability offered by the ESC sys-
tem is reduced.
•Trailer Sway Control (TSC) is disabled when the
ESC system is in the'Partial Off'mode.
4WD Low Range
Partial Off
This is the normal operating mode for ESC in 4WD LOW
range. Whenever the vehicle is started in 4WD LOW
range, or the transfer case (if equipped) is shifted from
4WD HIGH range or NEUTRAL to 4WD LOW range, the
ESC system will be in the “Partial Off” mode.
Trailer Sway Control (TSC)
TSC uses sensors in the vehicle to recognize an exces-
sively swaying trailer and will take the appropriate
actions to attempt to stop the sway. The system may
reduce engine power and apply the brake of the appro-
priate wheel(s) to counteract the sway of the trailer. TSC
will become active automatically once an excessively
swaying trailer is recognized. Note that TSC cannot stop
all trailers from swaying. Always use caution when
towing a trailer and follow the trailer tongue weight
recommendations. Refer to “Trailer Towing” in this sec-
tion for further 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
