2015 JEEP CHEROKEE lock

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.

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

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
5
STARTING AND OPERATING 521

wheel. This will allow more engine torque to be applied
to the wheel that is not spinning. This feature remains
active even if TCS and ESC are in the “Partial Off” mode
or the “Full Off” mode. Refer to “Electronic Stability
Control (ESC)” in this section for further information.
Brake Assist System (BAS)
The BAS is designed to optimize the vehicle’s braking
capability during emergency braking maneuvers. The
system detects an emergency braking situation by sens-
ing the rate and amount of brake application and then
applies optimum pressure to the brakes. This can help
reduce braking distances. The BAS complements the
anti-lock brake system (ABS). Applying the brakes very
quickly results in the best BAS assistance. To receive the
benefit of the system, you must apply continuous brak-
ing pressure during the stopping sequence, (do not
“pump” the brakes). Do not reduce brake pedal pressure
unless braking is no longer desired. Once the brake pedal
is released, the BAS is deactivated.
WARNING!
The Brake Assist System (BAS) cannot prevent the
natural laws of physics from acting on the vehicle,
nor can it increase the traction afforded by prevailing
road conditions. BAS cannot prevent collisions, in-
cluding those resulting from excessive speed in
turns, driving on very slippery surfaces, or hydro-
planing. The capabilities of a BAS-equipped vehicle
must never be exploited in a reckless or dangerous
manner, which could jeopardize the user’s safety or
the safety of others.
522 STARTING AND OPERATING

•Some additives used in regular gasoline are not fully
compatible with E-85 and may form deposits in your
engine. To eliminate driveability issues that may be
caused by these deposits, a supplemental gasoline
additive, such as MOPAR® Injector Cleanup or
Techron may be used.
Selection Of Engine Oil For Flexible Fuel Vehicles
(E-85) And Gasoline Vehicles
FFV vehicles operated on E-85 require specially formu-
lated engine oils. These special requirements are included
in MOPAR® engine oils, and in equivalent oils meeting
Chrysler Specification MS-6395. The manufacturer only
recommends engine oils that are API Certified and meet
the requirements of Material Standard MS-6395. MS-6395
contains additional requirements, developed during ex-
tensive fleet testing, to provide additional protection to
Chrysler Group LLC engines. Use MOPAR® or an
equivalent oil meeting the specification MS-6395.
Starting
The characteristics of E-85 fuel make it unsuitable for use
when ambient temperatures fall below 0°F (-18°C). In the
range of 0°F (-18°C) to 32°F (0°C), you may experience an
increase in the time it takes for your engine to start, and
a deterioration in driveability (sags and/or hesitations)
until the engine is fully warmed up.
NOTE:Use of the engine block heater (if equipped) is
beneficial for E-85 startability when the ambient tempera-
ture is less than 32°F (0°C).
Cruising Range
Because E-85 fuel contains less energy per gallon/liter
than gasoline, you will experience an increase in fuel
consumption. You can expect your miles per gallon
(mpg)/miles per liter and your driving range to decrease
by about 30%, compared to gasoline operation.

WARNING!(Continued)
•Vehicles with trailers should not be parked on a
grade. When parking, apply the parking brake on
the tow vehicle. Put the tow vehicle transmission in
PARK. Always, block or%chock%the trailer wheels.
•GCWR must not be exceeded.
•Total weight must be distributed between the tow
vehicle and the trailer such that the following four
ratings are not exceeded:
1. GVWR
2. GTW
3. GAWR
4. Tongue weight rating for the trailer hitch uti-
lized.
CAUTION!
•Do not tow a trailer at all during the first 500 miles
(805 km) the new vehicle is driven. The engine, axle
or other parts could be damaged.
•Then, during the first 500 miles (805 km) that a
trailer is towed, do not drive over 50 mph (80 km/h)
and do not make starts at full throttle. This helps
the engine and other parts of the vehicle wear in at
the heavier loads.
Towing Requirements — Tires
•Do not attempt to tow a trailer while using a compact
spare tire.
•Proper tire inflation pressures are essential to the safe
and satisfactory operation of your vehicle. Refer to
“Tires – General Information” in “Starting And Oper-
ating” for proper tire inflation procedures.
