2017 JEEP GRAND CHEROKEE warning

Rear Cross Path (RCP)
The Rear Cross Path (RCP) feature is intended to aid the
driver when backing out of parking spaces where their
vision of oncoming 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 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, includ-
ing reducing 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.

SAFETY 201

Operation is subject to the following two conditions:
1. The device may not cause harmful interference.
2. The device must accept any interference received, in-cluding interference that may cause undesired operation
of the device.
Changes or modifications to any of these systems by other
than an authorized service facility could void authorization
to use this equipment.
Forward Collision Warning (FCW) With Mitigation
The Forward Collision Warning (FCW) system with Miti-
gation provides the driver with audible warnings, visual
warnings (within the instrument cluster display), and may
apply a brake jerk to warn the driver when it detects a
potential frontal collision. The warnings and limited brak-
ing 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 progres-
sive 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.
If a Forward Collision Warning with Mitigation event
begins at a speed below 26 mph (42 km/h), the system may
provide the maximum or partial braking to mitigate the
potential forward collision. If the Forward Collision Warn-
ing with Mitigation event stops the vehicle completely, the
system will hold the vehicle at a standstill for two seconds
and then release the brakes.

SAFETY 203

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 1 mph
(2 km/h).
• The FCW alerts may be triggered on objects other than
vehicles such as guard rails or sign posts based on the
course prediction. This is expected and is a part of
normal FCW activation and functionality. •
It is unsafe to test the FCW system. To prevent such
misuse of the system, after four Active Braking events
within an ignition cycle, the Active Braking portion of
FCW will be deactivated until the next ignition cycle.
• The FCW system is intended for on-road use only. If the
vehicle is taken off-road, the FCW system should be
deactivated to prevent unnecessary warnings to the
surroundings. If the vehicle enters 4WD Low Range or
ESC Full-Off Mode is active, the FCW system will be
automatically deactivated.
WARNING!
Forward Collision Warning (FCW) is not intended to
avoid a collision on its own, nor can FCW detect every
type of potential collision. The driver has the respon-
sibility to avoid a collision by controlling the vehicle
via braking and steering. Failure to follow this warn-
ing could lead to serious injury or death.
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.
FCW Message
204 SAFETY

The forward collision button is located in the Uconnect
display in the controls settings.
To turn the FCW system OFF, press the forward collision
button once to turn the system OFF.
To turn the FCW system back on, press the forward
collision button again to turn the system on.
Changing the FCW status to “OFF” prevents the system
from warning you of a possible collision with the vehicle in
front of you.
NOTE:The FCW system state is kept in memory from one
ignition cycle to the next. If the system is turned OFF, it will
remain off when the vehicle is restarted.
Changing FCW And Active Braking Status
The FCW Sensitivity And Active Braking Settings are
programmable through the Uconnect System. Refer to
“Uconnect Settings” in “Multimedia” for further informa-
tion.
The default status of FCW is the “Medium” setting and the
Active Braking is in the “on” setting. This allows the
system to warn the driver of a possible collision with the
vehicle in front using audible/visual warnings and it
applies autonomous braking. Changing the FCW status to “Far” setting allows the
system to warn the driver of a possible collision with the
vehicle in front using audible/visual warning when the
latter is at a farther distance than
Mediumsetting. This
provides the most reaction time to avoid a possible colli-
sion.
Changing the FCW status to the “Near” setting, allows the
system to warn the driver of a possible collision with the
vehicle in front when the distance between the vehicle in
the front is much closer. This setting provides less reaction
time than the “Far” and “Medium” settings, which allows
for a more dynamic driving experience.
Changing the Active Braking status to “off” prevents the
system from providing autonomous braking, or additional
brake support if the driver is not braking adequately in the
event of a potential frontal collision.
NOTE:
• The system will retain the last setting selected by the
driver after ignition shut down.
• FCW may not react to irrelevant objects such as over-
head objects, ground reflections, objects not in the path
5
SAFETY 205

of the vehicle, stationary objects that are far away,
oncoming traffic, or leading vehicles with the same or
higher rate of speed.
• FCW will be disabled like ACC, with the unavailable
screens.
FCW Limited Warning
If the instrument cluster displays “ACC/FCW Limited
Functionality” or “ACC/FCW Limited Functionality Clean
Front Windshield” momentarily, there may be a condition
that limits FCW functionality. Although the vehicle is still
drivable under normal conditions, the active braking may
not be fully available. Once the condition that limited the
system performance is no longer present, the system will
return to its full performance state. If the problem persists,
see your authorized dealer.
Service FCW Warning
If the system turns off, and the instrument cluster displays:
• ACC/FCW Unavailable Service Required
• Cruise/FCW Unavailable Service Required
This indicates there is an internal system fault. Although
the vehicle is still drivable under normal conditions, have
the system checked by an authorized dealer.
Tire Pressure Monitor System (TPMS)
NOTE: For vehicles equipped with run flat tires — When
the TPMS indicates a tire pressure of 14 psi (96 kPa) or
lower, always check tire pressure and replace the tire at the
first opportunity. At inflation pressure of/or below 14 psi
(96 kPa) the tire is in the run-flat mode of operation. In this
condition, it is recommended a vehicle maximum speed of
50 mph (80 km/h) for a maximum distance of 50 miles
(80 km). The manufacturer does not recommend using the
run flat feature while driving a vehicle loaded at full
capacity or towing a trailer.
The Tire Pressure Monitoring System (TPMS) will warn the
driver of a low tire pressure based on the vehicle recom-
mended cold tire pressure.
The tire pressure will vary with temperature by about 1 psi
(7 kPa) for every 12°F (6.5°C). This means that when the
outside temperature decreases, the tire pressure will de-
crease. Tire pressure should always be set based on cold
inflation tire pressure. This is defined as the tire pressure
after the vehicle has not been driven for at least three
hours, or driven less than 1 mile (1.6 km) after a three-hour
period. Refer to “Tires” in “Servicing And Maintenance”
for information on how to properly inflate the vehicle’s
206 SAFETY

tires.The tire pressure will also increase as the vehicle is
driven - this is normal and there should be no adjustment
for this increased pressure.
The TPMS will warn the driver of a low tire pressure if the
tire pressure falls below the low pressure warning thresh-
old for any reason, including low temperature effects, or
natural pressure loss through the tire.
The TPMS will continue to warn the driver of low tire
pressure as long as the condition exists, and will not turn
off until the tire pressure is at or above recommended cold
tire pressure. Once the low tire pressure warning has been
illuminated, the tire pressure must be increased to the
recommended cold tire pressure in order for the Tire
Pressure Monitoring Telltale Light to be turned off.
NOTE: When filling warm tires, the tire pressure may need
to be increased up to an additional 4 psi (30 kPa) above the
recommended cold placard pressure in order to turn the
Tire Pressure Monitoring Telltale Light off.
The system will automatically update and the Tire Pressure
Monitoring Telltale Light will extinguish once the updated
tire pressures have been received. The vehicle may need to
be driven for up to 20 minutes above 15 mph (24 km/h) to
receive this information. For example, your vehicle has a recommended cold
(parked for more than three hours) tire pressure of 33 psi
(227 kPa). If the ambient temperature is 68°F (20°C) and the
measured tire pressure is 28 psi (193 kPa), a temperature
drop to 20°F (-7°C) will decrease the tire pressure to
approximately 24 psi (165 kPa). This tire pressure is suffi-
ciently low enough to turn ON the Tire Pressure Monitor-
ing Telltale Light. Driving the vehicle may cause the tire
pressure to rise to approximately 28 psi (193 kPa), but the
Tire Pressure Monitoring Telltale Light will still be ON. In
this situation, the Tire Pressure Monitoring Telltale Light
will turn OFF only after the tires have been inflated to the
vehicle’s recommended cold tire pressure value.
CAUTION!
•
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warnings have been established for the tire size
equipped on your vehicle. Undesirable system op-
eration or sensor damage may result when using
replacement equipment that is not of the same size,
type, and/or style. Aftermarket wheels can cause
sensor damage. Using aftermarket tire sealants may

SAFETY 207

CAUTION!(Continued)
cause the Tire Pressure Monitoring System (TPMS)
sensor to become inoperable. After using an after-
market tire sealant it is recommended that you take
your vehicle to an authorized dealership to have your
sensor function checked.
• After inspecting or adjusting the tire pressure, al-
ways reinstall the valve stem cap. This will prevent
moisture and dirt from entering the valve stem,
which could damage the Tire Pressure Monitoring
Sensor.
NOTE:
• The TPMS is not intended to replace normal tire care and
maintenance, or to provide warning of a tire failure or
condition.
• The TPMS should not be used as a tire pressure gauge
while adjusting your tire pressure.
• Driving on a significantly under-inflated tire causes the
tire to overheat and can lead to tire failure. Under-
inflation also reduces fuel efficiency and tire tread life,
and may affect the vehicle’s handling and stopping
ability. •
The TPMS is not a substitute for proper tire mainte-
nance, and it is the driver ’s responsibility to maintain
correct tire pressure using an accurate tire gauge, even if
under-inflation has not reached the level to trigger
illumination of the Tire Pressure Monitoring Telltale
Light.
• Seasonal temperature changes will affect tire pressure,
and the TPMS will monitor the actual tire pressure in the
tire.
Premium System
The Tire Pressure Monitor System (TPMS) uses wireless
technology with wheel rim-mounted electronic sensors to
monitor tire pressure levels. Sensors, mounted to each
wheel as part of the valve stem, transmit tire pressure
readings to the Receiver Module.
208 SAFETY

NOTE:It is particularly important, for you to regularly
check the tire pressure in all of your tires and to maintain
the proper pressure.
The Tire Pressure Monitor System (TPMS) consists of the
following components:
• Receiver Module
• Four Tire Pressure Monitoring Sensors •
Various Tire Pressure Monitoring System Messages,
which display in the instrument cluster, and a graphic
displaying tire pressures
• Tire Pressure Monitoring Telltale Light
Tire Pressure Monitoring Low Pressure Warnings
The Tire Pressure Monitoring Telltale Light will
illuminate in the instrument cluster, and an audible
chime will be activated, when one or more of the four
active road tire pressures are low. In addition, the instru-
ment cluster will display a Tire Lowmessage, an Inflate
to XXX message and a graphic display of the pressure
value(s) with the low tire(s) displayed in a different color.
Refer to “Instrument Cluster Display” in “Getting To Know
Your Instrument Panel” for further information.
NOTE: Your system can be set to display pressure units in
PSI, BAR or kPa.
