2014 JEEP GRAND CHEROKEE parking brake

When the parking brake is applied with the ignition
switch in the ON position, the “Brake Warning Light” in
the instrument cluster will illuminate.
NOTE:
•When the parking brake is applied and the transmis-
sion is placed in gear, the “Brake Warning Light” will
flash. If vehicle speed is detected, a chime will sound
to alert the driver. Fully release the parking brake
before attempting to move the vehicle.
• This light only shows that the parking brake is ap-
plied. It does not show the degree of brake application. 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 parking
brake before placing the shift lever in PARK, otherwise
the load on the transmission locking mechanism may
make it difficult to move the shift lever 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 move-
ment and possible injury or damage.
• When leaving the vehicle, always remove the Key
Fob from the ignition and lock your vehicle.

WARNING!(Continued)
•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 shift lever.
• When leaving the vehicle, always make sure the
keyless ignition node is in the “OFF” mode, re-
move the Key Fob from the vehicle and lock the
vehicle.
(Continued)
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 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.
• 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 leav-
ing 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.

STARTING AND OPERATING 445

CAUTION!
If the “Brake Warning Light” remains on with the
parking brake released, a brake system malfunction
is indicated. Have the brake system serviced by an
authorized dealer immediately.
ELECTRONIC BRAKE CONTROL SYSTEM
Your vehicle is equipped with an advanced electronic
brake control system that includes the Anti-Lock Brake
System (ABS), Traction Control System (TCS), Brake
Assist System (BAS), Electronic Roll Mitigation (ERM),
and Electronic Stability Control (ESC). All five of these
systems work together to enhance vehicle stability and
control in various driving conditions.Also, your vehicle may be equipped with Trailer Sway
Control (TSC), Hill Start Assist (HSA), Ready Alert
Braking (RAB), Rain Brake Support (RBS) and, if it has
four-wheel drive with the MP 3023 two-speed transfer
case, Hill Descent Control (HDC), Selec Speed Control
(SSC).
Anti-Lock Brake System
The Anti-Lock Brake System (ABS) is designed to aid the
driver in maintaining vehicle control under adverse
braking conditions. The system operates with a separate
computer to modulate hydraulic pressure to prevent
wheel lock-up and help avoid skidding on slippery
surfaces.
All vehicle wheels and tires must be the same size and
type, and tires must be properly inflated to produce
accurate signals for the computer.
446 STARTING AND OPERATING

WARNING!(Continued)
•HSA is not a parking brake. If you stop the vehicle
on a hill without putting the transmission in PARK
and using the parking brake, it will roll down the
hill and could cause a collision with another ve-
hicle or object. Always remember to use the park-
ing brake while parking on a hill, and that the
driver is responsible for braking the vehicle.
HSA Off
If you wish to turn off the HSA system, it can be done
using the Uconnect® Access Settings. Refer to
“Uconnect® Access Settings” in “Understanding Your
Instrument Panel” for further information.
Ready Alert Braking — If Equipped
Ready Alert Braking may reduce the time required to
reach full braking during emergency braking situations.
It anticipates when an emergency braking situation may occur by monitoring how fast the throttle is released by
the driver. When the throttle is released very quickly,
Ready Alert Braking applies a small amount of brake
pressure. This brake pressure will not be noticed by the
driver. The brake system uses this brake pressure to allow
a fast brake response if the driver applies the brakes.
Rain Brake Support — If Equipped
Rain Brake Support may improve braking performance
in wet conditions. It will periodically apply a small
amount of brake pressure to remove any water buildup
on the front brake rotors. It only functions when the
windshield wipers are in the LO or HI mode, it does not
function in the intermittent mode. When Rain Brake
Support is active, there is no notification to the driver and
no driver interaction is required.
456 STARTING AND OPERATING

Hill Descent Control (HDC) — If Equipped
(Four-Wheel Drive Models With MP3023
Two-Speed Transfer Case Only)
HDC is intended for low speed off road driving while in
4WD Low Range. HDC maintains vehicle speed whiledescending 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 vehicle speed).
Enabling HDC
HDC is enabled by pressing the HDC switch, but the
following conditions must also be met to enable HDC:
• Driveline is in 4WD Low Range
• Vehicle speed is below 5mph (8 km/h)
• Parking brake is released
• Driver door is closed

STARTING AND OPERATING 457

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.

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)

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.
