2019 JEEP GRAND CHEROKEE LIMITED Owners Manual

NOTE:TSC cannot stop all trailers from swaying. Always
use caution when towing a trailer and follow the trailer
tongue weight recommendations. Refer to “Trailer Tow-
ing” in “Starting And Operating” 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 attempt to stop the trailer from
swaying. TSC is disabled when the ESC system is in the
“Partial Off” or “Full Off” modes.

NOTE:The DST feature is only meant to help the driver
realize the correct course of action through small torques
on the steering wheel, which means the effectiveness of the
DST feature is highly dependent on the driver ’s sensitivity
and overall reaction to the applied torque. It is very
important to realize that this feature will not steer the
vehicle, meaning the driver is still responsible for steering
the vehicle.
Hill Descent Control (HDC) — If Equipped
HDC is intended for low speed off road driving while in
4WD Low Range. HDC maintains vehicle speed while
descending hills during various driving situations. HDC
controls vehicle speed by actively controlling the brakes.
HDC Has Three States:
1. Off (feature is not enabled and will not activate).
2. Enabled (feature is enabled and ready but activation conditions are not met, or driver is actively overriding
with brake or throttle application).
3. Active (feature is enabled and actively controlling ve- hicle speed). Enabling HDC
HDC is enabled by pushing the HDC switch, but the
following conditions must also be met to enable HDC:
•
Driveline is in 4WD Low Range.
• Vehicle speed is below 5 mph (8 km/h).
• Parking brake is released.
• Driver door is closed.
Activating HDC
Once HDC is enabled it will activate automatically if
driven down a grade of sufficient magnitude. The set speed
for HDC is selectable by the driver, and can be adjusted by
using the gear shift +/-. The following summarizes the
HDC set speeds:
HDC Target Set Speeds
• P = No set speed. HDC may be enabled but will not
activate.
• R = 0.6 mph (1 km/h)
• N = 1.2 mph (2 km/h)
176 SAFETY

•D = 0.6 mph (1 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)
• 9th = 5.6 mph (9 km/h) – If Equipped
NOTE: During HDC the +/- shifter input is used for HDC
target speed selection, but will not affect the gear chosen by
the transmission. When actively controlling HDC the trans-
mission will shift appropriately for the driver-selected set
speed and corresponding driving conditions.
Driver Override
The driver may override HDC activation with throttle or
brake application at anytime. 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 magnitude,
is on level ground, or is on an uphill grade.
• Vehicle is shifted to park.
Disabling HDC
HDC will be deactivated and disabled if any of the
following conditions occur:
• The driver pushes 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.

SAFETY 177

•The vehicle is driven greater than 40 mph (64 km/h)
(HDC exits immediately).
• HDC detects excessive brake temperature.
Feedback To The Driver
The instrument cluster has an HDC icon and the HDC
switch has an LED icon, 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.
• The cluster icon and switch lamp will flash for several
seconds then extinguish when the driver pushes the
HDC switch but enable conditions are not met.
• The cluster icon and switch lamp will flash for several
seconds then extinguish when HDC disables 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.

•Vehicle speed is below 5 mph (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 gear shift +/-. Additionally, the SSC
set speed may be reduced when climbing a grade and the
level of set speed reduction depends on the magnitude of
grade. The following summarizes the SSC set speeds:
SSC Target Set Speeds
• 1st = .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 mph (8 km/h)
• 9th = 5.6 mph (9 km/h) – If Equipped
• REVERSE = .6 mph (1 km/h)
• NEUTRAL = 1.2 mph (2 km/h)
• PARK = SSC remains enabled but not active
NOTE:
• During SSC the +/- shifter input is used for SSC target
speed selection but will not affect the gear chosen by the
transmission. While actively controlling SSC the trans-
mission will shift appropriately for the driver-selected
set speed and corresponding driving conditions.
• SSC performance is influenced by the Terrain Select
mode. This difference may be notable to the driver and
may be perceived as a varying level of aggressiveness.

WARNING!
SSC is only intended to assist the driver in controlling
vehicle speed when driving in off road conditions. The
driver must remain attentive to the driving conditions
and is responsible for maintaining a safe vehicle
speed.
AUXILIARY DRIVING SYSTEMS
Blind Spot Monitoring (BSM) — If Equipped
The Blind Spot Monitoring (BSM) system uses two radar
sensors, located inside the rear bumper fascia, to detect
highway licensable vehicles (automobiles, trucks, motor-
cycles, etc.) that enter the blind spot zones from the
rear/front/side of the vehicle.When the vehicle is started, the BSM warning light will
momentarily illuminate in both outside rear view mirrors
to let the driver know that the system is operational. The
BSM system sensors operate when the vehicle is in any
forward gear or REVERSE.

The BSM detection zone covers approximately one lane
width on both sides of the vehicle 12 ft (3.8 m). The zone
length starts at the side of the vehicle, near the B-Pillar, and
extends approximately 10 ft (3 m) beyond the rear bumper
of the vehicle. The BSM system monitors the detection
zones on both sides of the vehicle when the vehicle speed
reaches approximately 6 mph (10 km/h) or higher and will
alert the driver of vehicles in these areas.
NOTE:
•The BSM system DOES NOT alert the driver about
rapidly approaching vehicles that are outside the detec-
tion zones.
• The BSM system detection zone DOES NOT change if
your vehicle is towing a trailer. Therefore, visually verify
the adjacent lane is clear for both your vehicle and trailer
before making a lane change. If the trailer or other object
(i.e., bicycle, sports equipment) extends beyond the side
of your vehicle, this may result in random false detec-
tions on the trailer, and false chimes when the turn
signal is used.
• The BSM system may experience drop outs (blinking on
and off) of the side mirror Warning Indicator lamps when a motorcycle or any small object remains at the
side of the vehicle for extended periods of time (more
than a couple of seconds).
The area on the rear fascia where the radar sensors are
located must remain free of snow, ice, and dirt/road
contamination so that the BSM system can function prop-
erly. Do not block the area of the rear fascia where the radar
sensors are located with foreign objects (bumper stickers,
bicycle racks, etc.).
