JEEP CHEROKEE 2014 KL / 5.G Owners Manual

Traction Downhill
Shift the transmission into a low gear and the 4WD
System to 4WD LOW range or Select Hill Descent
Control if equipped (refer toElectronic Brake Control
System in this section for further information). Let the
vehicle go slowly down the hill with all four wheels
turning against engine compression drag. This will per-
mit you to control the vehicle speed and direction.
When descending mountains or hills, repeated braking
can cause brake fade with loss of braking control. Avoid
repeated heavy braking by downshifting the transmis-
sion whenever possible.
After Driving Off-Road
Off-road operation puts more stress on your vehicle than
does most on-road driving. After going off-road, it is
always a good idea to check for damage. That way you can get any problems taken care of right away and have
your vehicle ready when you need it.
•
Completely inspect the underbody of your vehicle.
Check tires, body structure, steering, suspension, and
exhaust system for damage.
• Inspect the radiator for mud and debris and clean as
required.
• Check threaded fasteners for looseness, particularly on
the chassis, drivetrain components, steering, and sus-
pension. Retighten them, if required, and torque to the
values specified in the Service Manual.
• Check for accumulations of plants or brush. These
things could be a fire hazard. They might hide damage
to fuel lines, brake hoses, axle pinion seals, and
propeller shafts.

STARTING AND OPERATING 449

•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

If the “SERVICE POWER STEERING” message
and a steering wheel icon are displayed on the
EVIC screen, it indicates that the vehicle needs
to be taken to the dealer for service. It is likely
the vehicle has lost power steering assistance. Refer to
“Electronic Vehicle Information (EVIC)” in “Understand-
ing Your Instrument Panel” for further information.
NOTE:
• Even if the power steering assistance is no longer
operational, it is still possible to steer the vehicle.
Under these conditions there will be a substantial
increase in steering effort, especially at low speeds and
during parking maneuvers.
• If the condition persists, see your authorized dealer for
service.ELECTRIC PARKING BRAKE (EPB)
Your vehicle is equipped with an Electric Parking Brake
System (EPB) that offers simple operation, and some
additional features that make the parking brake more
convenient and useful.
The parking brake is primarily intended to prevent the
vehicle from rolling while parked. Before leaving the
vehicle, make sure that the parking brake is applied.
Also, be certain to leave the transmission in PARK.
You can engage the parking brake in two ways;
• Manually, by applying the park brake switch.
• Automatically, by enabling the Auto Park Brake fea-
ture in the customer programmable features section of
the Uconnect® settings.
5
STARTING AND OPERATING 451

The parking brake switch is located in the center console.
To apply the parking brake manually, pull up on the
switch momentarily. You may hear a slight whirring
sound from the back of the vehicle while the parking
brake engages. Once the parking brake is fully engaged,
the BRAKE warning lamp in the instrument cluster andan indicator on the switch will illuminate. If your foot is
on the brake pedal while you apply the parking brake,
you may notice a small amount of brake pedal move-
ment. The park brake can be applied even when the
ignition switch is OFF but the BRAKE warning lamp will
not illuminate, however, it can only be released when the
ignition switch is in the ON/RUN position.
NOTE:
The EPB fault lamp will illuminate if the EPB
switch is held for longer than 20 seconds in either the
released or applied position. The light will extinguish
upon releasing the switch.
If the Auto Park Brake feature is enabled, the parking
brake will automatically engage whenever the transmis-
sion is placed into PARK, or with a manual transmission,
when the ignition switch is turned OFF. Once the parking
brake is engaged, the BRAKE warning lamp in the
instrument cluster and the LED indicator on the switch
Electric Parking Brake Switch
452 STARTING AND OPERATING

will illuminate. If your foot is on the brake pedal, you
may notice a small amount of brake pedal movement
while the parking brake is engaging.
The parking brake will release automatically when the
ignition switch is ON, the transmission is in Drive or
Reverse, the driver seat belt is buckled, and an attempt is
made to drive away.
To release the park brake manually, the ignition switch
must be in the ON/RUN position. Put your foot on the
brake pedal, then push the parking brake switch down
momentarily. You may hear a slight whirring sound from
the back of the car while the parking brake disengages.
You may also notice a small amount of movement in the
brake pedal. Once the parking brake is fully disengaged,
The BRAKE warning lamp in the instrument cluster and
the LED indicator on the switch will extinguish.NOTE:
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 mecha-
nism 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.

STARTING AND OPERATING 453

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
454 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 system.
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 programmable
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.

STARTING AND OPERATING 455

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.
456 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.

STARTING AND OPERATING 457

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.
