key JEEP CHEROKEE 2017 KL / 5.G Service Manual

•It is unsafe to test the FCW system. To prevent such
misuse of the system, after four Active Braking events
within a key cycle, the Active Braking portion of FCW
will be deactivated until the next key 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.
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.
The forward collision button is located on the switch panel
below the Uconnect display. To turn the FCW system OFF, push the forward collision
button once to turn the system OFF (LED turns on).
To turn the FCW system back on, push the forward
collision button again to turn the system on (LED turns
off).
•
Changing the FCW status to “Off” prevents the system
from warning you of a possible collision with the vehicle
in front of you.
• Changing the FCW sensitivity - Near vs. Far. Far warns
the driver of a possible collision earlier and Near warns
the driver later.

SAFETY 193

•Changing the Active Braking status to “Off” prevents
the system from providing limited active braking, or
additional brake support if the driver is not braking
adequately in the event of a potential frontal collision,
but maintains the audible and visual warnings.
NOTE: The FCW system state is kept in memory from one
key 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 “Far” setting and the
Active Braking is the “On” setting, 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.
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
allows for a more dynamic driving experience.
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
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 display reads “ACC/FCW Lim-
ited 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.
194 SAFETY

If the ignition key is cycled, this sequence will repeat,
providing the system fault still exists. If the system fault no
longer exists, the “Tire Pressure Monitoring Telltale Light”
will no longer flash, and the “SERVICE TPM SYSTEM”
message will no longer display, and a pressure value will
display in place of the dashes. A system fault can occur due
to any of the following:
1. Jamming due to electronic devices or driving next tofacilities emitting the same radio frequencies as the
TPMS sensors. 2. Installing some form of aftermarket window tinting that
affects radio wave signals.
3.
Lots of snow or ice around the wheels or wheel housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPMS sensors.
Vehicles With Compact Spare or Non-Matching Full Size
Spare
1. The compact spare tire or non-matching full size does not have a tire pressure monitoring sensor. Therefore,
the TPMS will not monitor the pressure in the compact
spare tire.
2. If you install the compact or non-matching full size spare tire in place of a road tire that has a pressure below
the low-pressure warning limit, upon the next ignition
key cycle, the “TPMS Telltale Light” will remain on and
a chime will sound. In addition, the graphic in the
instrument cluster will still display a different color
pressure value and an Inflate to XXmessage.

SAFETY 199

3.After driving the vehicle for up to 20 minutes above
15.5 mph (25 km/h), the “TPMS Telltale Light” will flash
on and off for 75 seconds and then remain on solid. In
addition, the instrument cluster will display a “SERVICE
TPM SYSTEM” message for five seconds and then display
dashes (- -) in place of the pressure value.
4. For each subsequent ignition key cycle, a chime willsound, the “TPMS Telltale Light” will flash on and off
for 75 seconds and then remain on solid, and the
instrument cluster will display a “SERVICE TPM SYS-
TEM” message for five seconds and then display dashes
(- -) in place of the pressure value.
5.
Once you repair or replace the original road tire and
reinstall it on the vehicle in place of the compact spare or
non-matching full size, the TPMS will update automati-
cally. In addition, the “TPMS Telltale Light” will turn off
and the graphic in the instrument cluster will display a
new pressure value instead of dashes (- -), as long as no
tire pressure is below the low-pressure warning limit in
any of the four active road tires. The vehicle may need to
be driven for up to 20 minutes above 15.5 mph (25 km/h)
in order for the TPMS to receive this information.
TPMS Deactivation — If Equipped
The TPMS can be deactivated if replacing all four wheel
and tire assemblies (road tires) with wheel and tire assem-
blies that do not have TPMS Sensors, such as when
installing winter wheel and tire assemblies on your vehicle.
To deactivate the TPMS, first, replace all four wheel and
tire assemblies (road tires) with tires not equipped with
Tire Pressure Monitoring (TPM) Sensors. Then, drive the
vehicle for 10 minutes above 15.5 mph (25 km/h). The
TPMS will chime, the TPM Telltale Lightwill flash on and
off for 75 seconds and then remain on. The instrument
cluster will display the “SERVICE TPM SYSTEM” message
and then display dashes (--) in place of the pressure values.
Beginning with the next ignition cycle, the TPMS will no
longer chime or display the “SERVICE TPM SYSTEM”
message in the instrument cluster but dashes (--) will
remain in place of the pressure values.
To reactivate the TPMS, replace all four wheel and tire
assemblies (road tires) with tires equipped with TPM
sensors. Then, drive the vehicle for up to 10 minutes above
15.5 mph (25 km/h). The TPMS will chime, the TPM
Telltale Light will flash on and off for 75 seconds and then
turn off. The instrument cluster will display the “SERVICE
TPM SYSTEM” message and then display pressure values

WARNING!(Continued)
•NEVER place any objects under the floor mat (e.g.,
towels, keys, etc.). These objects could change the
position of the floor mat and may cause interference
with the accelerator, brake, or clutch pedals.
• If the vehicle carpet has been removed and re-
installed, always properly attach carpet to the floor
and check the floor mat fasteners are secure to the
vehicle carpet. Fully depress each pedal to check for
interference with the accelerator, brake, or clutch
pedals then re-install the floor mats.
• It is recommended to only use mild soap and water
to clean your floor mats. After cleaning, always check
your floor mat has been properly installed and is
secured to your vehicle using the floor mat fasteners
by lightly pulling mat.
Periodic Safety Checks You Should Make Outside
The Vehicle
Tires
Examine tires for excessive tread wear and uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread or sidewall. Inspect the tread for cuts
and cracks. Inspect sidewalls for cuts, cracks, and bulges.
Check the wheel nuts for tightness. Check the tires (includ-
ing spare) for proper cold inflation pressure.
Lights
Have someone observe the operation of brake lights and
exterior lights while you work the controls. Check turn signal
and high beam indicator lights on the instrument panel.
Door Latches
Check for proper closing, latching, and locking.
Fluid Leaks
Check area under vehicle after overnight parking for fuel,
engine coolant, oil, or other fluid leaks. Also, if gasoline
fumes are detected or if fuel, power steering fluid (if
equipped), or brake fluid leaks are suspected. The cause
should be located and corrected immediately.

•When leaving the vehicle, always remove the key fob
from the ignition and lock your vehicle. If equipped
with Keyless Enter-N-Go, always make sure the
keyless ignition node is in “OFF” mode, remove the
key fob from the vehicle and lock the vehicle.
• Never leave children alone in a vehicle, or with
access to an unlocked vehicle.
• Allowing children to be in a vehicle unattended is
dangerous for a number of reasons. A child or others
could be seriously or fatally injured. Children
should be warned not to touch the parking brake,
brake pedal or the gear selector.
• Do not leave the key fob in or near the vehicle, or in
a location accessible to children, and do not leave the
ignition of a vehicle equipped with Keyless Enter-
N-Go in the ACC or ON/RUN mode. A child could
operate power windows, other controls, or move the
vehicle. Start the engine with the gear selector in the NEUTRAL or
PARK position. Apply the brake before shifting to any
driving range.
Normal Starting — Gasoline Engine
NOTE:
Normal starting of either a cold or a warm engine
is obtained without pumping or pressing the accelerator
pedal.
Cycle the ignition to the START mode and release when the
engine starts. If the engine fails to start within 10 seconds,
cycle the ignition to the LOCK/OFF mode, wait 10 to 15
seconds, then repeat the “Normal Starting” procedure.
Tip Start Feature
Cycle the ignition to START mode and release it as the
starter engages. The starter motor will automatically dis-
engage itself once engine is running. If the engine fails to
start, the starter will disengage automatically in 10 sec-
onds. If this occurs, cycle the ignition to the OFF mode,
wait 10 to 15 seconds, then repeat the “Normal Starting”
procedure.

STARTING AND OPERATING 261

NOTE:When parking on a hill, it is important to turn the
front wheels toward the curb on a downhill grade and
away from the curb on an uphill grade. Apply the park
brake before placing the gear selector in PARK, otherwise
the load on the transmission locking mechanism may make
it difficult to move the gear selector out of PARK. The
parking brake should always be applied whenever the
driver is not in the vehicle.
WARNING!
• Never use the PARK position as a substitute for the
parking brake. Always apply the parking brake fully
when parked to guard against vehicle movement and
possible injury or damage.
• When leaving the vehicle, always remove the key fob
from the ignition and lock your vehicle.
• Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Allowing children to
be in a vehicle unattended is dangerous for a number
of reasons. A child or others could be seriously or
fatally injured. Children should be warned not to
touch the parking brake, brake pedal or the gear
selector.

WARNING! (Continued)
•Do not leave the key fob in or near the vehicle, or in
a location accessible to children, and do not leave a
vehicle equipped with Keyless Enter-N-Go in the
ACC or ON/RUN mode. A child could operate power
windows, other controls, or move the vehicle.
• Be sure the parking brake is fully disengaged before
driving; failure to do so can lead to brake failure and
a collision.
• Always fully apply the parking brake when leaving
your vehicle, or it may roll and cause damage or
injury. Also be certain to leave the transmission in
PARK. Failure to do so may allow the vehicle to roll
and cause damage or injury.
CAUTION!
If the Brake System Warning Light remains on with the
parking brake released, a brake system malfunction is
indicated. Have the brake system serviced by an au-
thorized dealer immediately.
266 STARTING AND OPERATING

AUTOMATIC TRANSMISSION
WARNING!
•It is dangerous to shift out of PARK or NEUTRAL if
the engine speed is higher than idle speed. If your
foot is not firmly pressing the brake pedal, the
vehicle could accelerate quickly forward or in re-
verse. You could lose control of the vehicle and hit
someone or something. Only shift into gear when the
engine is idling normally and your foot is firmly
pressing the brake pedal.
• Unintended movement of a vehicle could injure
those in or near the vehicle. As with all vehicles, you
should never exit a vehicle while the engine is
running. Before exiting a vehicle, always apply the
parking brake, shift the transmission into PARK,
turn the engine OFF, and remove the key fob. When
the ignition is in the LOCK/OFF (key removal)
position, (or, with Keyless Enter-N-Go, when the
ignition is in the OFF mode) the transmission is
locked in PARK, securing the vehicle against un-
wanted movement.
(Continued)
WARNING! (Continued)
•When leaving the vehicle, always make sure the
ignition is in the OFF mode, remove the key fob from
the vehicle, and lock the vehicle.
• Never use the PARK position as a substitute for the
parking brake. Always apply the parking brake fully
when parked to guard against vehicle movement and
possible injury or damage.
• Your vehicle could move and injure you and others if
it is not in PARK. Check by trying to move the gear
selector out of PARK with the brake pedal released.
Make sure the transmission is in PARK before leav-
ing the vehicle.
• Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Allowing children to
be in a vehicle unattended is dangerous for a number
of reasons. A child or others could be seriously or
fatally injured. Children should be warned not to
touch the parking brake, brake pedal or the trans-
mission gear selector.

WARNING!(Continued)
•Do not leave the key fob in or near the vehicle (or in
a location accessible to children), and do not leave
the ignition (in a vehicle equipped with Keyless
Enter-N-Go) in the ACC or ON/RUN mode. A child
could operate power windows, other controls, or
move the vehicle.
CAUTION!
Damage to the transmission may occur if the following
precautions are not observed:
• Shift into or out of PARK or REVERSE only after the
vehicle has come to a complete stop.
• Do not shift between PARK, REVERSE, NEUTRAL,
or DRIVE when the engine is above idle speed.
• Before shifting into any gear, make sure your foot is
firmly pressing the brake pedal.
NOTE: You must press and hold the brake pedal while
shifting out of PARK.
Key Ignition Park Interlock
This vehicle is equipped with a Key Ignition Park Interlock
which requires the transmission to be in PARK before the
ignition can be turned to the LOCK/OFF (key removal)
position. The key fob can only be removed from the
ignition when the ignition is in the LOCK/OFF position,
and the transmission is locked in PARK whenever the
ignition is in the LOCK/OFF position.
Brake/Transmission Shift Interlock System
This vehicle is equipped with a Brake Transmission Shift
Interlock system (BTSI) that holds the transmission gear
selector in PARK unless the brakes are applied. To shift the
transmission out of PARK, the ignition must be turned to
the ON/RUN mode (engine running or not) and the brake
pedal must be pressed.
The brake pedal must also be pressed to shift from NEU-
TRAL into DRIVE or REVERSE when the vehicle is
stopped or moving at low speeds.
