2015 JEEP CHEROKEE brake

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 lever. Additionally, the
SSC set speed is automatically 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:
4WD Low Range Set Speeds
•1st = .6 mph (1 km/h)
•2nd = 1.2 mph (2 km/h)
•3rd = 4 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)
•REVERSE = .6 mph (1 km/h)
•NEUTRAL = 1.2 mph (2 km/h)
•PARK = SSC remains enabled but not active

STARTING AND OPERATING 531

NOTE:These SSC default set speeds are dependent on
hill grade. That is the steeper the grade of the hill the
vehicle travels on the lower the values of the set speed
will be for all listed gears, with the minimal value being
.6 mph (1 km/h).
NOTE:
•During SSC the ERS +/- shifter input is used for SSC
target speed selection but will not affect the gear
chosen by the transmission. During SSC the transmis-
sion 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.
Driver Override:
The driver may override SSC activation with throttle or
brake application at any time.
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.
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.
532 STARTING AND OPERATING

•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)
(SSC exits immediately).
Feedback To The Driver:
The instrument cluster has an SSC icon and the SSC
switch has an LED which offer 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.
•The cluster icon and switch lamp will flash then
extinguish when SSC deactivates due to overheated
brakes.
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.
Electronic Stability Control (ESC)
This system enhances directional control and stability of
the vehicle under various driving conditions. ESC cor-
rects for oversteering or understeering of the vehicle by
applying the brake of the appropriate wheel to assist in
counteracting the oversteer or understeer condition. En-
gine power may also be reduced to help the vehicle
maintain the desired path.
5
STARTING AND OPERATING 533

ESC uses sensors in the vehicle to determine the vehicle
path intended by the driver and compares it to the actual
path of the vehicle. When the actual path does not match
the intended path, ESC applies the brake of the appro-
priate wheel to assist in counteracting the oversteer or
understeer condition.
•Oversteer - when the vehicle is turning more than
appropriate for the steering wheel position.
•Understeer - when the vehicle is turning less than
appropriate for the steering wheel position.
The “ESC Activation/Malfunction Indicator Light” lo-
cated in the instrument cluster will start to flash as soon
as the tires lose traction and the ESC system becomes
active. The “ESC Activation/Malfunction Indicator
Light” also flashes when the TCS is active. If the “ESC
Activation/Malfunction Indicator Light” begins to flash
during acceleration, 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.
WARNING!
The Electronic Stability Control (ESC) cannot pre-
vent the natural laws of physics from acting on the
vehicle, nor can it increase the traction afforded by
prevailing road conditions. ESC cannot prevent col-
lisions, including those resulting from excessive
speed in turns, driving on very slippery surfaces, or
hydroplaning. ESC also cannot prevent collisions
resulting from loss of vehicle control due to inappro-
priate driver input for the conditions. Only a safe,
attentive, and skillful driver can prevent collisions.
The capabilities of an ESC equipped vehicle must
never be exploited in a reckless or dangerous manner
which could jeopardize the user ’s safety or the safety
of others.
534 STARTING AND OPERATING

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.
Trailer Sway Control (TSC)
The TSC system uses sensors in the vehicle to recognize
an excessively swaying trailer and will take the appro-
priate actions to attempt to stop the sway. The system
may reduce engine power and apply the brake of the
appropriate wheel(s) to counteract the sway of the trailer.
TSC will become active automatically once an excessively
swaying trailer is recognized.
Always use caution when towing a trailer and follow the
trailer tongue weight recommendations. 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
only active in the default “ESC On” mode. TSC can be
disabled by pressing the “ESC Off” switch and entering
“ESC Partial Off” mode. It is not active in the “ESC
Partial Off” or “ESC Full Off” modes. Refer to the ESC
portion of this section for an explanation of the different
ESC operating modes.
NOTE:TSC cannot stop all trailers from swaying.
WARNING!
If the TSC activates while driving, slow the vehicle
down, stop at the nearest safe location, and adjust the
trailer load to eliminate trailer sway.

Ready Alert Braking (RAB)
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 (RBS)
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 is triggered by the windshield
wiper setting and only functions when they are in use.
When Rainy Brake Support is active, there is no notifica-
tion to the driver and no driver interaction is required.

540 STARTING AND OPERATING

specified weight limitations are met. Store the heavier
items down low and be sure that the weight is distributed
equally. Stow all loose items securely before driving.
Improper weight distributions can have an adverse effect
on the way your vehicle steers and handles and the way
the brakes operate.
CAUTION!
Do not load your vehicle any heavier than the GVWR
or the maximum front and rear GAWR. If you do,
parts on your vehicle can break, or it can change the
way your vehicle handles. This could cause you to
lose control. Also overloading can shorten the life of
your vehicle.
TRAILER TOWING
In this section you will find safety tips and information
on limits to the type of towing you can reasonably do
with your vehicle. Before towing a trailer, carefully
review this information to tow your load as efficiently
and safely as possible.
To maintain the New Vehicle Limited Warranty coverage,
follow the requirements and recommendations in this
manual concerning vehicles used for trailer towing.
Common Towing Definitions
The following trailer towing related definitions will assist
you in understanding the following information:
Gross Vehicle Weight Rating (GVWR)
The GVWR is the total allowable weight of your vehicle.
This includes driver, passengers, cargo and tongue
weight. The total load must be limited so that you do not

tow vehicle’s front axle and the trailer axle(s). When used
in accordance with the manufacturer’s directions, it pro-
vides for a more level ride, offering more consistent
steering and brake control thereby enhancing towing
safety. The addition of a friction/hydraulic sway control
also dampens sway caused by traffic and crosswinds and
contributes positively to tow vehicle and trailer stability.
Trailer sway control and a weight distributing (load
equalizing) hitch are recommended for heavier Tongue
Weights (TW) and may be required depending on vehicle
and trailer configuration/loading to comply with Gross
Axle Weight Rating (GAWR) requirements.
WARNING!
•An improperly adjusted Weight Distributing Hitch
system may reduce handling, stability, braking
performance, and could result in a collision.
•Weight Distributing Systems may not be compat-
ible with Surge Brake Couplers. Consult with your
hitch and trailer manufacturer or a reputable Rec-
reational Vehicle dealer for additional information.
