service JEEP CHEROKEE 2014 KL / 5.G Repair Manual

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.

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.

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.

Tire Repair
If your tire becomes damaged, it may be repaired if it
meets the following criteria:
•The tire has not been driven on when flat.
• The damage is only on the tread section of your tire
(sidewall damage is not repairable).
• The puncture is no greater than ¼ (6 mm).
Consult an authorized tire dealer for tire repairs and
additional information.
Damaged Run Flat tires, or Run Flat tires that have
experienced a loss of pressure should be replaced imme-
diately with another Run Flat tire of identical size and
service description (Load Index and Speed Code).Tire Types
All Season Tires — If Equipped
All Season tires provide traction for all seasons (spring,
summer, fall and winter). Traction levels may vary be-
tween different all season tires. All season tires can be
identified by the M+S, M&S, M/S or MS designation on
the tire sidewall. Use all season tires only in sets of four;
failure to do so may adversely affect the safety and
handling of your vehicle.
Summer Or Three Season Tires — If Equipped
Summer tires provide traction in both wet and dry
conditions, and are not intended to be driven in snow or
on ice. If your vehicle is equipped with summer tires, be
aware these tires are not designed for winter or cold
driving conditions. For more information, contact a au-
thorized dealer. Summer tires do not contain the all
season designation or mountain/snowflake symbol on
the tire sidewall.

Tread Wear Indicators
Tread wear indicators are in the original equipment tires
to help you in determining when your tires should be
replaced.These indicators are molded into the bottom of the tread
grooves. They will appear as bands when the tread depth
becomes 1/16 in (2 mm). When the tread is worn to the
tread wear indicators, the tire should be replaced. Refer
to “Replacement Tires” in this section for further infor-
mation.
Life Of Tire
The service life of a tire is dependent upon varying
factors including, but not limited to:
•
Driving style
• Tire pressure
• Distance driven
• Performance tires, tires with a speed rating of V or
higher, and summer tires typically have a reduced
tread life. Rotation of these tires per the vehicle main-
tenance schedule is highly recommended.

Tire Pressure Monitoring Low Pressure Warnings
The “Tire Pressure Monitoring Telltale Light” will
illuminate in the instrument cluster, a “LOW TIRE
PRESSURE” message will display in the instrument
cluster, an Inflate to XX message will be displayed and
a chime will sound when tire pressure is low in one or
more of the four active road tires. Should this occur, you
should stop as soon as possible, check the inflation
pressure of each tire on your vehicle, and inflate each tire
to the vehicle’s recommended cold placard pressure
value as shown in the Inflate to XXmessage. Once the
system receives the updated tire pressures, the system
will automatically update and the “Tire Pressure Moni-
toring Telltale Light” will turn off. The vehicle may need
to be driven for up to 20 minutes above 15 mph
(24 km/h) in order for the TPMS to receive this
information.
Service TPMS Warning
When a system fault is detected, the “Tire Pressure
Monitoring Telltale Light” will flash on and off for
75 seconds and then remain on solid. The system fault
will also sound a chime. If the ignition key is cycled, this
sequence will repeat, providing the system fault still
exists. The “Tire Pressure Monitoring Telltale Light” will
turn off when the fault condition no longer exists. A
system fault can occur due to any of the following:
1. Jamming due to electronic devices or driving next to facilities emitting the same radio frequencies as the
TPMS sensors.
2. Installing some form of aftermarket window tinting that affects radio wave signals.
3.
Lots of snow or ice around the wheels or wheel hous-
ings.
