2015 JEEP CHEROKEE four wheel drive

NOTE:Any chassis/suspension or tire size modifications
to the vehicle will effect the performance of the Adaptive
Cruise Control and Forward Collision Warning System.
Activating Adaptive Cruise Control (ACC)
You can only engage ACC if the vehicle speed is above
0 mph (0 km/h).
The minimum Set Speed for the ACC system is 20 mph
(32 km/h).
When the system is turned on and in the READY state,
the Electronic Vehicle Information Center (EVIC) or
Driver Information Display (DID) displays “ACC
Ready.”
When the system is OFF, the EVIC/DID displays “Adap-
tive Cruise Control (ACC) Off.”
NOTE:You cannot engage ACC under the following
conditions:
•When in Four-Wheel Drive Low.
•When you apply the brakes.
•When the parking brake is set.
•When the automatic transmission is in PARK, RE-
VERSE or NEUTRAL.
•When the Vehicle speed is outside of the speed range.
•When the brakes are overheated.
•When the driver door is open.
•When the driver seat belt is unbuckled.

•The shift lever/gear selector is removed from the
Drive position.
•The Electronic Stability Control/Traction Control Sys-
tem (ESC/TCS) activates.
•The vehicle parking brake is applied.
•Driver seatbelt is unbuckled at low speeds.
•Driver door is opened at low speeds.
•A Trailer Sway Control (TSC) event occurs.
•The driver switches ESC to full-off mode.
To Turn Off
The system will turn off and clear the set speed in
memory if:
•The Adaptive Cruise Control (ACC) ON/OFF button
is pressed.
•The Normal (Fixed Speed) Electronic Speed Control
ON/OFF button is pressed.
•The ignition is turned OFF.
•You switch to Four-Wheel Drive Low.
To Resume
If there is a set speed in memory press the RES (resume)
button and then remove your foot from the accelerator
pedal. The EVIC/DID will display the last set speed.
NOTE:
•If your vehicle stays at standstill for longer than two
seconds, then the driver will either have to press the
RES (resume) button, or apply the accelerator pedal to
reengage the ACC to the existing Set Speed.
•ACC cannot be resumed if there is a stationary vehicle
in-front of your vehicle in close proximity.

To Turn Off
The system will turn off and erase the set speed in
memory if:
•The Normal (Fixed Speed) Electronic Speed Control
ON/OFF button is pressed.
•The ignition is turned off.
•You engage Four-Wheel Drive Low.
•The Adaptive Cruise Control (ACC) On/Off button is
pressed.
FORWARD COLLISION WARNING (FCW) WITH
MITIGATION — IF EQUIPPED
Forward Collision Warning (FCW) With Mitigation
Operation
The Forward Collision Warning (FCW) system with
mitigation provides the driver with audible warnings,
visual warnings (within the EVIC/DID), 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 deter-
mines that the driver intends to avoid the collision by

•Electronic Throttle Control (ETC) Light
This light informs you of a problem with
the Electronic Throttle Control (ETC) sys-
tem. The light will come on when the
ignition is first turned ON and remain on
briefly as a bulb check. If the light does not come on
during starting, have the system checked by an
authorized dealer.
If a problem is detected, the light will come on while
the engine is running. Cycle the ignition key when
the vehicle has completely stopped and the shift lever
is placed in the PARK position. The light should turn
off.
If the light remains lit with the engine running, your
vehicle will usually be drivable. However, see an
authorized dealer for service as soon as possible. If
the light is flashing when the engine is running,
immediate service is required. You may experience
reduced performance, an elevated/rough idle or en-
gine stall and your vehicle may require towing.
•Oil Temperature Warning Light
This telltale indicates engine oil tempera-
ture is high. If the light turns on while
driving, stop the vehicle and shut off the
engine as soon as possible.
•Secondary Air Bag Warning Light
If the light turns on while driving, have the
system inspected at an authorized dealer as
soon as possible. Refer to “Occupant Re-
straints” in “Things To Know Before Start-
ing Your Vehicle” for further information.
14. 4WD LOW Indicator Light — If Equipped
This light alerts the driver that the vehicle is in the
four-wheel drive LOW mode. The front and rear drive-
shafts are mechanically locked together forcing the front

and rear wheels to rotate at the same speed. Low range
provides a greater gear reduction ratio to provide in-
creased torque at the wheels.
For further information on four-wheel drive operation
and proper use, refer to “Four-Wheel Drive Operation —
If Equipped” in “Starting And Operating”.
15. SERV 4WD Indicator Light — If Equipped
This light alerts the driver that the 4WD is in need of
service. If this light is illuminated, see your authorized
dealer as soon as possible.
16. Temperature Gauge
The temperature gauge shows engine coolant tempera-
ture. Any reading within the normal range indicates that
the engine cooling system is operating satisfactorily.
The gauge pointer will likely indicate a higher tempera-
ture when driving in hot weather, up mountain grades,
or when towing a trailer. It should not be allowed to
exceed the upper limits of the normal operating range.
CAUTION!
Driving with a hot engine cooling system could
damage your vehicle. If the temperature gauge reads
“H” pull over and stop the vehicle. Idle the vehicle
with the air conditioner turned off until the pointer
drops back into the normal range. If the pointer
remains on the “H” and you hear continuous chimes,
turn the engine off immediately and call an autho-
rized dealer for service.
WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call an authorized dealer
for service if your vehicle overheats. If you decide to
look under the hood yourself, see “Maintaining Your

•Low Coolant Level Indicator
This telltale will turn on to indicate the
vehicle coolant level is low.
•Windshield Washer Fluid Low Indicator
This telltale will turn on to indicate the
windshield washer fluid is low.
•4WD LOW Indicator Light — If Equipped
This light alerts the driver that the vehicle is in the
four-wheel drive LOW mode. The front and rear
driveshafts are mechanically locked together forcing
the front and rear wheels to rotate at the same speed.
Low range provides a greater gear reduction ratio to
provide increased torque at the wheels.
For further information on four-wheel drive opera-
tion and proper use, refer to “Four-Wheel Drive
Operation — If Equipped” in “Starting And
Operating”.
•SERV 4WD Indicator Light — If Equipped
This light alerts the driver that the 4WD is in need of
service. If this light is illuminated, see your autho-
rized dealer as soon as possible.
•Adaptive Cruise Control (ACC) Malfunction
This light will turn on when a ACC is not
operating and needs service. For further
information, refer to “Adaptive Cruise
Control (ACC)” in “Understanding The
Features Of Your Vehicle”.
•LaneSense Service — If Equipped
This telltale will turn on to indicate that the
Lane Sense Departure has detected a
failure.

468 STARTING AND OPERATING

NOTE:The torque converter clutch will not engage until
the transmission fluid is warm (usually after 1 to 3 miles
[2 to 5 km] of driving). Because the engine speed is higher
when the torque converter clutch is not engaged, it may
seem as if the transmission is not shifting properly when
cold, this is normal. The torque converter clutch will
function normally once the transmission is sufficiently
warm.
FOUR-WHEEL DRIVE OPERATION
1-Speed Four-Wheel Drive (4X4) — If Equipped
This feature provides on-demand four-wheel drive (4X4).
The system is automatic with no driver inputs or addi-
tional driving skills required. Under normal driving
conditions, the front wheels provide most of the traction.
If the front wheels begin to lose traction, power is shifted
automatically to the rear wheels. The greater the front
wheel traction loss, the greater the power transfer to the
rear wheels.
