2014 JEEP CHEROKEE brakes

If the ABS light is on, the brake system should be serviced
as soon as possible to restore the benefits of Anti-Lock
brakes. If the ABS light does not turn on when the
ignition switch is turned to the ON/RUN position, have
the light inspected by an authorized dealer.
8. Electronic Stability Control (ESC) Activation/
Malfunction Indicator Light — If EquippedThe “ESC Activation/Malfunction Indicator
Light” in the instrument cluster will come on
when the ignition switch is turned 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 authorized dealer as soon as possible to have the
problem diagnosed and corrected.
NOTE:
•The “ESC Off Indicator Light” and the “ESC
Activation/Malfunction Indicator Light” come on
momentarily each time the ignition switch is turned
to ON/RUN.
• Each time the ignition is turned to ON/RUN, the
ESC system will be ON, even if it was turned off
previously.
• 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.

•Forward Collision Warning (FCW) Active Braking —
If Equipped
The FCW system includes Advanced Brake Assist (ABA).
When this feature is selected, it will apply the brakes to
slow your vehicle in case of potential forward collision.
The ABA applies additional brake pressure when the
driver requests insufficient brake pressure to avoid a
potential frontal collision. The ABA system becomes
active at 5 mph (8 km/h).
For further information, refer to “Forward Collision
Warning (FCW) With Mitigation” in “Understanding The
Features Of Your Vehicle”.
• Lane Departure Warning (LDW) — If Equipped
When this feature is selected, it sets the distance at which
the steering wheel will provide feedback for potential
lane departures. The LDW sensitivity can be set to
provide either an “early”, “medium” or “late” warning
zone start point. For further information, refer to “Lane Departure Warn-
ing (LDW)” in “Understanding The Features Of Your
Vehicle”.
•
Lane Departure Torque — If Equipped
When this feature is selected, it sets the strength of the
steering wheel feedback for potential lane departures.
The amount of directional torque the steering system can
apply to the steering wheel to correct for vehicle lane
departure can be set at “Low,” “Medium” or “High.”
For further information, refer to “Lane Departure Warn-
ing (LDW)” in “Understanding The Features Of Your
Vehicle”.
• ParkSense® Active Park Assist — If Equipped
The Rear Park Assist system will scan for objects behind
the vehicle when the transmission shift lever is in RE-
VERSE and the vehicle speed is less than 11 mph

Key Ignition Park Interlock
This vehicle is equipped with a Key Ignition Park Inter-
lock which requires the transmission to be in PARK
before the ignition switch can be turned to the full OFF
(key removal) position. The key fob can only be removed
from the ignition when the ignition is in the full OFF
position, and the transmission is locked in PARK when-
ever the ignition switch is in the full OFF position.
Brake/Transmission Shift Interlock System
This vehicle is equipped with a Brake Transmission Shift
Interlock system (BTSI) that holds the shift lever in PARK
unless the brakes are applied. To shift the transmission
out of PARK, the ignition switch must be turned to the
ON/RUN position (engine running or not) and the brake
pedal must be pressed.
Nine-Speed Automatic Transmission
Your vehicle is equipped with a state of the art, fuel
efficient nine-speed transmission. The transmission gear
range (PRND) is displayed both beside the shift lever and
in the Electronic Vehicle Information Center (EVIC). To
select a gear range, press the lock button on the shift lever
and move the lever rearward or forward. You must also
press the brake pedal to shift the transmission out of PARK,
or to shift from NEUTRAL into DRIVE or REVERSE when
the vehicle is stopped or moving at low speeds (refer to
Brake/Transmission Shift Interlock Systemin this sec-
tion). Select the DRIVE range for normal driving.
The electronically-controlled transmission provides a pre-
cise shift schedule. The transmission electronics are self-
calibrating; therefore, the first few shifts on a new vehicle
may be somewhat abrupt. This is a normal condition, and
precision shifts will develop within a few hundred miles
(kilometers).
426 STARTING AND OPERATING

Avoid abrupt downshifts on icy or slippery roads be-
cause engine braking may cause skidding and loss of
control.
Hill Climbing
NOTE:Before attempting to climb a hill, determine the
conditions at the crest and/or on the other side.
Before climbing a steep hill, shift the transmission to a
lower gear and shift the 4WD System to 4WD LOW. Use
first gear and 4WD LOW for very steep hills.
If you stall or begin to lose headway while climbing a
steep hill, allow your vehicle to come to a stop and
immediately apply the brakes. Restart the engine and
shift to REVERSE. Back slowly down the hill allowing the
compression braking of the engine to help regulate your
speed. If the brakes are required to control vehicle speed,
apply them lightly and avoid locking or skidding the
tires.
WARNING!
If the engine stalls or you lose headway or cannot
make it to the top of a steep hill or grade, never
attempt to turn around. To do so may result in
tipping and rolling the vehicle. Always back straight
down a hill in REVERSE gear carefully. Never back
down a hill in NEUTRAL using only the brake.
Remember, never drive diagonally across a hill - drive
straight up or down.
If the wheels start to slip as you approach the crest of a
hill, ease off the accelerator and maintain headway by
turning the front wheels slowly left and right. This may
provide a fresh “bite” into the surface and will usually
provide traction to complete the climb.
448 STARTING AND OPERATING

•After extended operation in mud, sand, water, or
similar dirty conditions, have the radiator, fan, brake
rotors, wheels, brake linings, and axle yokes inspected
and cleaned as soon as possible.
WARNING!
Abrasive material in any part of the brakes may cause
excessive wear or unpredictable braking. You might
not have full braking power when you need it to
prevent a collision. If you have been operating your
vehicle in dirty conditions, get your brakes checked
and cleaned as necessary.
• If you experience unusual vibration after driving in
mud, slush or similar conditions, check the wheels for
impacted material. Impacted material can cause a
wheel imbalance and freeing the wheels of it will
correct the situation.
POWER STEERING
The electric power steering system will give you good
vehicle response and increased ease of maneuverability
in tight spaces. The system will vary its assist to provide
light efforts while parking and good feel while driving. If
the electric steering system experiences a fault that
reduces assist or prevents the vehicle from providing
assist, you will still have the ability to steer the vehicle
manually.
WARNING!
Continued operation with reduced assist could pose
a safety risk to yourself and others. Service should be
obtained as soon as possible.
450 STARTING AND OPERATING

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.
When servicing your rear brakes, it may be necessary for
you or your technician 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
mechanic.
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.
