JEEP GRAND CHEROKEE 2014 WK2 / 4.G Owners Manual

Deactivating HDC
HDC will be deactivated but remain available if any of
the following conditions occur:
•Driver overrides HDC set speed with throttle or brake
application.
• Vehicle speed exceeds 20 mph (32 km/h) but remains
below 40 mph (64 km/h).
• Vehicle is on a downhill grade of insufficient magni-
tude (less than approximately 8%), is on level ground,
or is on an uphill grade.
• Vehicle is shifted to park.
Disabling HDC
HDC will deactivate and be disabled if any of the
following conditions occur:
• The driver presses the HDC switch. •
The driveline is shifted out of 4WD Low Range.
• The parking brake is applied.
• Driver door opens.
• The vehicle is driven greater than 20 mph (32 km/h)
for greater than 70 seconds.
• The vehicle is driven greater than 40 mph (64 km/h)
(HDC exits immediately).
Feedback to the driver:
The instrument cluster has a HDC icon and a HDC
switch which has an LED which offers feedback to the
driver about the state HDC is in.
• The cluster icon and switch lamp will illuminate and
remain on solid when HDC is enabled or activated.
This is the normal operating condition for HDC.

STARTING AND OPERATING 459

•The cluster icon and switch lamp will flash for several
seconds then extinguish when the driver presses the
HDC switch but enable conditions are not met.
• The cluster icon and switch lamp will flash for several
seconds then extinguish when HDC deactivates due to
excess speed.
• The cluster icon and switch lamp will flash when HDC
deactivates due to overheated brakes. The flashing will
stop and HDC will activate again once the brakes have
cooled sufficiently.
WARNING!
HDC is only intended to assist the driver in control-
ling vehicle speed when descending hills. The driver
must remain attentive to the driving conditions and
is responsible for maintaining a safe vehicle speed.
Select Speed Control (SSC) — If Equipped
(Four-Wheel Drive Models With MP3023
Two-Speed Transfer Case Only)
SSC is intended for off road driving in 4WD Low Range
only. SSC maintains vehicle speed by actively controlling
engine torque and brakes.
Select Speed Control Switch
460 STARTING AND OPERATING

SSC has three states:
1. Off (feature is not enabled and will not activate)
2. Enabled (feature is enabled and ready but activationconditions are not met, or driver is actively overriding
with brake or throttle application)
3. Active (feature is enabled and actively controlling vehicle speed)
Enabling SSC
SSC is enabled by pressing the SSC switch, but the
following conditions must also be met to enable SSC:
• Driveline is in 4WD Low Range
• Vehicle speed is below 5mph (8 km/h)
• Parking brake is released
• Driver door is closed
• Driver is not applying throttle Activating SSC
Once SSC is enabled it will activate automatically once
the following conditions are met:
•
Driver releases throttle
• Driver releases brake
• Transmission is in any selection other than P
• Vehicle speed is below 20 mph (32 km/h)
The set speed for SSC is selectable by the driver, and can
be adjusted by using the paddle shifter ’s. Additionally,
the SSC set speed is automatically reduced when climb-
ing a grade and the level of set speed reduction depends
on the magnitude of grade. The following summarizes
the SSC set speeds:
• P = No set speed. SSC may be enabled but will not
activate.
• R = 0.6 mph (1 km/h)
5
STARTING AND OPERATING 461

•N = 1.2 mph (2 km/h)
• 1st = 0.6 mph (1 km/h)
• 2nd = 1.2 mph (2 km/h)
• 3rd = 1.8 mph (3 km/h)
• 4th = 2.5 mph (4 km/h)
• 5th = 3.1 mph (5 km/h)
• 6th = 3.7 mph (6 km/h)
• 7th = 4.3 mph (7 km/h)
• 8th = 5.0 mph (8 km/h)
NOTE: During SSC the +/- paddle shifter input is used
for SSC target speed selection and will put the transmis-
sion into ERS but will not affect the gear chosen by the
transmission unless in Driver Override. During SSC the
transmission will shift appropriately for the driver-
selected set speed and corresponding driving conditions. Driver Override:
The driver may override SSC activation with throttle or
brake application at any time. While in driver override
the transmission will be in ERS which is a top gear limiter
and the vehicle will shift from 1st through whichever
gear is displayed.
Deactivating SSC
SSC will be deactivated but remain available if any of the
following conditions occur:
•
Driver overrides SSC set speed with throttle or brake
application.
• Vehicle speed exceeds 20 mph (32 km/h) but remains
below 40 mph (64 km/h).
• Vehicle is shifted to park.
462 STARTING AND OPERATING

Disabling SSC
SSC will deactivate and be disabled if any of the follow-
ing conditions occur:
•The driver presses the SSC switch
• The driveline is shifted out of 4WD Low Range.
• The parking brake is applied.
• Driver door opens.
• The vehicle is driven faster than 20 mph (32 km/h) for
longer than 70 seconds.
• The vehicle is driven greater than 40 mph (64 km/h) (
SSC exits immediately)
Feedback to the driver:
The instrument cluster has an SSC icon and the SSC
switch has an LED which offers feedback to the driver
about the state SSC is in. •
The cluster icon and switch lamp will illuminate and
remain on solid when SSC is enabled or activated. This
is the normal operating condition for SSC.
• The cluster icon and switch lamp will flash for several
seconds then extinguish when the driver presses the
SSC switch but enable conditions are not met.
• The cluster icon and switch lamp will flash for several
seconds then extinguish when SSC deactivates due to
excess speed.
WARNING!
SSC is only intended to assist the driver in control-
ling vehicle speed when driving in off road condi-
tions. The driver must remain attentive to the driving
conditions and is responsible for maintaining a safe
vehicle speed.

STARTING AND OPERATING 463

ESC Activation/Malfunction Indicator Light And
ESC OFF Indicator Light
The “ESC Activation/Malfunction Indicator
Light” in the instrument cluster will come on
when the ignition switch is cycled to the ON/
RUN position. It should go out with the engine
running. If the “ESC Activation/Malfunction Indicator
Light” comes on continuously with the engine running, a
malfunction has been detected in the ESC system. If this
light remains on after several ignition cycles, and the
vehicle has been driven several miles (kilometers) at
speeds greater than 30 mph (48 km/h), see your autho-
rized dealer as soon as possible to have the problem
diagnosed and corrected. The “ESC Activation/Malfunction Indicator Light” (lo-
cated in the instrument cluster) starts to flash as soon as
the tires lose traction and the ESC system becomes active.
The “ESC Activation/Malfunction Indicator Light” also
flashes when TCS is active. If the “ESC Activation/
Malfunction Indicator Light” begins to flash during ac-
celeration, ease up on the accelerator and apply as little
throttle as possible. Be sure to adapt your speed and
driving to the prevailing road conditions.
NOTE:
•
The “ESC Off Indicator Light” and the “ESC
Activation/Malfunction Indicator Light” come on mo-
mentarily each time the ignition switch is turned to the
ON/RUN position.
• Each time the ignition is cycled to the ON/RUN
position, the ESC system will be ON even if it was
cycled off previously.
464 STARTING AND OPERATING

•The ESC system will make buzzing or clicking sounds
when it is active. This is normal; the sounds will stop
when ESC becomes inactive following the maneuver
that caused the ESC activation.
The “ESC OFF Indicator Light” indicates the
Electronic Stability Control (ESC) is partially
off or full off.TIRE SAFETY INFORMATION

NOTE:
•P (Passenger) — Metric tire sizing is based on U.S.
design standards. P-Metric tires have the letter “P”
molded into the sidewall preceding the size designa-
tion. Example: P215/65R15 95H.
• European — Metric tire sizing is based on European
design standards. Tires designed to this standard have
the tire size molded into the sidewall beginning with
the section width. The letter Pis absent from this tire
size designation. Example: 215/65R15 96H.
• LT (Light Truck) — Metric tire sizing is based on U.S.
design standards. The size designation for LT-Metric
tires is the same as for P-Metric tires except for the
letters “LT” that are molded into the sidewall preced-
ing the size designation. Example: LT235/85R16. •
Temporary spare tires are designed for temporary
emergency use only. Temporary high pressure com-
pact spare tires have the letter “T” or “S” molded into
the sidewall preceding the size designation. Example:
T145/80D18 103M.
• High flotation tire sizing is based on U.S. design
standards and it begins with the tire diameter molded
into the sidewall. Example: 31x10.5 R15 LT.
