2015 JEEP CHEROKEE brake

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.
•Do not leave the Key Fob in or near the vehicle, or
in a location accessible to children, and do not
leave 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.
(Continued)
WARNING!(Continued)
•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.
CAUTION!
If the Brake System Warning Light remains on with
the parking brake released, a brake system malfunc-
tion is indicated. Have the brake system serviced by
an authorized dealer immediately.
If exceptional circumstances should make it necessary to
engage the parking brake while the vehicle is in motion,
maintain upward pressure on the electric park brake
switch for as long as engagement is desired. The Brake
warning lamp will illuminate, and a continuous chime
514 STARTING AND OPERATING

will sound. The rear stop lamps will also be illuminated
automatically while the vehicle remains in motion.
To disengage the parking brake while the vehicle is in
motion, release the switch. If the vehicle is brought to a
complete stop using the parking brake, when the vehicle
reaches approximately 3 mph, (5 km/h) the parking
brake will remain engaged.
WARNING!
Driving the vehicle with the parking brake engaged,
or repeated use of the parking brake to slow the
vehicle may cause serious damage to the brake sys-
tem.
In the unlikely event of a malfunction of the Electric Park
Brake system, a yellow EPB fault lamp will illuminate.
This may be accompanied by the Brake warning lamp
flashing. In this event, urgent service of the electric park
brake system is required. Do not rely on the parking
brake to hold the vehicle stationary.
Auto Park Brake
The electric park brake can be programmed to be applied
automatically whenever the vehicle is at a standstill and
the automatic transmission is placed in PARK, or with a
manual transmission, whenever the ignition switch is
turned “OFF”. Auto Park Brake is enabled and disabled
by customer selection through the customer program-
mable features section of the Uconnect® Settings.
Any single auto park brake application can be bypassed
by pressing the EPB switch to the release position while
the transmission is placed in PARK.

Safehold
Safehold is a safety feature of the Electric Park Brake
System that will engage the park brake automatically if
the vehicle is left unsecured while the ignition switch is
in RUN.
For automatic transmissions, the park brake will auto-
matically engage if all of the following conditions are
met:
•The vehicle is at a standstill
•There is no attempt to depress the brake pedal or
accelerator pedal
•The seat belt is unbuckled
•The driver door is open
For manual transmissions, the park brake will automati-
cally engage if all of the following conditions are met:
•The vehicle is at a standstill
•There is no attempt to depress the brake pedal or
accelerator pedal
•The clutch pedal is not pressed
•The seat belt is unbuckled
•The driver door is open
Safehold can be temporarily bypassed by pressing the
Electric Park Brake Switch while the driver door is open.
Once manually bypassed, Safehold will be enabled again
once the vehicle reaches 12 mph (20 km/h) or the ignition
is turned to the OFF position and back to ON again.
Brake Service Mode
We recommend having your brakes serviced by your
authorized dealer. You should only make repairs for
which you have the knowledge and the right equipment.
You should only enter Brake Service Mode during brake
service.
516 STARTING AND OPERATING

When servicing your rear brakes, it may be necessary for
you or your technician to push the rear piston into the
rear caliper bore. With the electric parking brake system,
this can only be done after retracting the Electric Parking
Brake actuator. Fortunately, actuator retraction can be
done easily by entering the Brake Service Mode through
the Uconnect® Settings in your vehicle. This menu based
system will guide you through the steps necessary to
retract the EPB actuator in order to perform rear brake
service.
Service Mode has requirements that must be met in order
to be activated:
•The vehicle must be at a standstill.
•The parking brake must be unapplied.
•The transmission must be in Park or Neutral.
While in service mode, the Electric Parking Brake fault lamp
will flash continuously while the ignition switch is ON.
When brake service work is complete, the following steps
must be followed to reset the parking brake system to
normal operation:
•Ensure the vehicle is at a standstill.
•Press the brake pedal with moderate force.
•Apply the Electric Parking Brake Switch.
WARNING!
You can be badly injured working on or around a
motor vehicle. Do only that service work for which
you have the knowledge and the right equipment. If
you have any doubt about your ability to perform a
service job, take your vehicle to a competent me-
chanic.

STARTING AND OPERATING 517

BRAKE SYSTEM
Your vehicle is equipped with dual hydraulic
brake systems. If either of the two hydraulic
systems loses normal capability, the remaining
system will still function. However, there will
be some loss of overall braking effectiveness. This will be
evident by increased pedal travel during application and
greater pedal force required to slow or stop the vehicle. In
addition, if the malfunction is caused by a leak in the
hydraulic system, the “Brake Warning Light” will turn on
as the brake fluid level drops in the master cylinder.
In the event power assist is lost for any reason (i.e.,
repeated brake applications with the engine OFF) the
brakes will still function. However, the effort required to
brake the vehicle will be much greater than that required
with the power system operating.
WARNING!
•Riding the brakes can lead to brake failure and
possibly a collision. Driving with your foot resting
or riding on the brake pedal can result in abnor-
mally high brake temperatures, excessive lining
wear, and possible brake damage. You would not
have your full braking capacity in an emergency.
•Driving a vehicle with the “Brake Warning Light”
on is dangerous. A significant decrease in braking
performance or vehicle stability during braking
may occur. It will take you longer to stop the
vehicle or will make your vehicle harder to control.
You could have a collision. Have the vehicle
checked immediately.
518 STARTING AND OPERATING

ELECTRONIC BRAKE CONTROL SYSTEM
Your vehicle is equipped with an advanced electronic
brake control system commonly referred to as ESC. This
system includes Anti-Lock Brake System (ABS), Traction
Control System (TCS), Brake Assist System (BAS), Hill
Start Assist (HSA), Electronic Roll Mitigation (ERM), and
Electronic Stability Control (ESC). These systems work
together to enhance both vehicle stability and control in
various driving conditions.
Your vehicle is also equipped with Trailer Sway Control
(TSC), Ready Alert Braking (RAB) and Rain Brake Sup-
port (RBS). Further, all vehicles equipped with a two-
speed power transfer unit have Hill Descent Control
(HDC) and some vehicles may also be equipped with
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.
WARNING!
Significant over or under-inflation of tires or mixing
sizes of tires or wheels on the vehicle can lead to loss
of braking effectiveness.
The ABS conducts a low-speed self-test at about 12 mph
(20 km/h). If you have your foot lightly on the brake
while this test is occurring, you may feel slight pedal
movement. The movement can be more apparent on ice
and snow. This is normal.
5
STARTING AND OPERATING 519

The ABS pump motor runs during the self-test at 12 mph
(20 km/h) and during an ABS stop. The pump motor
makes a low humming noise during operation, which is
normal.
WARNING!
•Pumping of the Anti-Lock Brakes will diminish
their effectiveness and may lead to a collision.
Pumping makes the stopping distance longer. Just
press firmly on your brake pedal when you need to
slow down or stop.
•The ABS cannot prevent the natural laws of phys-
ics from acting on the vehicle, nor can it increase
braking or steering efficiency beyond that afforded
by the condition of the vehicle brakes and tires or
the traction afforded.
(Continued)
WARNING!(Continued)
•The ABS cannot prevent collisions, including those
resulting from excessive speed in turns, following
another vehicle too closely, or hydroplaning.
•The capabilities of an ABS equipped vehicle must
never be exploited in a reckless or dangerous
manner, which could jeopardize the user’s safety or
the safety of others.
CAUTION!
The ABS is subject to possible detrimental effects of
electronic interference caused by improperly in-
stalled aftermarket radios or telephones.
NOTE:During severe braking conditions, a pulsing sen-
sation may occur and a clicking noise will be heard. This
is normal, indicating that the ABS is functioning.
520 STARTING AND OPERATING

•Do not “ride” the brakes by resting your foot on the
pedal. This could overheat the brakes and result in
unpredictable braking action, longer stopping dis-
tances, or brake damage.
•When descending mountains or hills, repeated braking
can cause brake fade with loss of braking control.
Avoid repeated heavy braking by downshifting the
transmission or locking out overdrive whenever pos-
sible.
•Engines may idle at higher speeds during warm-up,
which could cause rear wheels to spin and result in
loss of vehicle control. Be especially careful while
driving on slippery roads, in close-quarter maneuver-
ing, parking, or stopping.
•Do not drive too fast for road conditions, especially
when roads are wet or slushy. A wedge of water can
build up between the tire tread and the road. This
hydroplaning action can cause loss of traction, braking
ability, and control.
•After going through deep water or a car wash, brakes
may become wet, resulting in decreased performance
and unpredictable braking action. Dry the brakes by
gentle, intermittent pedal action while driving at very
slow speeds.
Traction Control System (TCS)
This system monitors the amount of wheel spin of each of
the driven wheels. If wheel spin is detected, brake
pressure is applied to the slipping wheel(s) and engine
power is reduced to provide enhanced acceleration and
stability. A feature of the TCS system, Brake Limited
Differential (BLD), functions similar to a limited slip
differential and controls the wheel spin across a driven
axle. If one wheel on a driven axle is spinning faster than
the other, the system will apply the brake of the spinning
