2016 JEEP CHEROKEE ABS

The dual brake system provides a reserve braking capac-
ity in the event of a failure to a portion of the hydraulic
system. A leak in either half of the dual brake system is
indicated by the Brake Warning Light, which will turn on
when the brake fluid level in the master cylinder has
dropped below a specified level.
The light will remain on until the cause is corrected.
NOTE:The light may flash momentarily during sharp
cornering maneuvers, which change fluid level condi-
tions. The vehicle should have service performed, and
the brake fluid level checked.If brake failure is indicated, immediate repair is necessary.
WARNING!
Driving a vehicle with the red brake light on is
dangerous. Part of the brake system may have failed.
It will take longer to stop the vehicle. You could have
a collision. Have the vehicle checked immediately.
Vehicles equipped with the Anti-Lock Brake System
(ABS) are also equipped with Electronic Brake Force
Distribution (EBD). In the event of an EBD failure, the
Brake Warning Light will turn on along with the ABS
Light. Immediate repair to the ABS system is required.

Anti-Lock Brake (ABS) Indicator Light
Yellow TelltaleLight What It Means
Anti-Lock Brake (ABS) Indicator Light
This light monitors the Anti-Lock Brake System (ABS). The light will turn on when the igni-
tion switch is placed in the ON/RUN position and may stay on for as long as four seconds.
If the ABS light remains on or turns on while driving, then the Anti-Lock portion of the
brake system is not functioning and service is required. However, the conventional brake
system will continue to operate normally if the brake warning light is not on.
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
placed in the ON/RUN position, have the light inspected by an authorized dealer.

ELECTRONIC BRAKE CONTROL SYSTEM
Your vehicle is equipped with an advanced Electronic
Brake Control system (EBC). This system includes Elec-
tronic Brake Force Distribution (EBD), Anti-Lock Brake
System (ABS), Brake Assist System (BAS), Hill Start
Assist (HSA), Traction Control System (TCS), Electronic
Stability Control (ESC), and Electronic Roll Mitigation
(ERM). These systems work together to enhance both
vehicle stability and control in various driving condi-
tions.
Your vehicle may also be equipped with Trailer Sway
Control (TSC), Ready Alert Braking (RAB), Rain Brake
Support (RBS), Dynamic Steering Torque (DST), Hill
Descent Control (HDC), and Selec-Speed Control (SSC).
Electronic Brake Force Distribution (EBD)
This function manages the distribution of the braking
torque between the front and rear axles by limiting
braking pressure to the rear axle. This is done to preventoverslip of the rear wheels to avoid vehicle instability,
and to prevent the rear axle from entering ABS before the
front axle.
Brake System Warning Light
The red “Brake System Warning Light” will turn on when
the ignition switch is turned to the ON position and may
stay on for as long as four seconds.
If the “Brake System Warning Light” remains on or
comes on while driving, it indicates that the brake system
is not functioning properly and that immediate service is
required. If the “Brake System Warning Light” does not
come on when the ignition switch is turned to the ON
position, have the light repaired as soon as possible.
Anti-Lock Brake System (ABS)
The Anti-Lock Brake System (ABS) provides increased
vehicle stability and brake performance under most
520 STARTING AND OPERATING

braking conditions. The system automatically prevents
wheel lock, and enhances vehicle control during braking.
The ABS performs a self-check cycle to ensure that the
ABS is working properly each time the vehicle is started
and driven. During this self-check you may hear a slight
clicking sound as well as some related motor noises.
ABS is activated during braking when the system detects
one or more wheels begins to lock. Road conditions such as
ice, snow, gravel, bumps, railroad tracks, loose debris, or
panic stops may increase the likelihood of ABS activation(s).
You also may experience the following when ABS activates:
•The ABS motor noise (it may continue to run for a
short time after the stop).
• The clicking sound of solenoid valves.
• Brake pedal pulsations.
• A slight drop of the brake pedal at the end of the stop. These are all normal characteristics of ABS.
WARNING!
•
The ABS contains sophisticated electronic equip-
ment that may be susceptible to interference
caused by improperly installed or high output
radio transmitting equipment. This interference
can cause possible loss of anti-lock braking capa-
bility. Installation of such equipment should be
performed by qualified professionals.
• 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

WARNING!(Continued)
braking or steering efficiency beyond that afforded
by the condition of the vehicle brakes and tires or
the traction afforded.
• 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 that could jeopardize the user ’s safety or
the safety of others.
ABS is designed to function with the OEM tires. Modifi-
cation may result in degraded ABS performance.
Anti-Lock Brake Warning Light
The amber “Anti-Lock Brake Warning Light” will turn on
when the ignition switch is turned to the ON position
and may stay on for as long as four seconds. If the “Anti-Lock Brake Warning Light” remains on or
comes on while driving, it indicates that the anti-lock
portion of the brake system is not functioning and that
service is required. However, the conventional brake
system will continue to operate normally if the “Brake
System Warning Light” is not on.
If the “Anti-Lock Brake Warning Light” is on, the brake
system should be serviced as soon as possible to restore
the benefits of anti-lock brakes. If the “Anti-Lock Brake
Warning Light” does not come on when the ignition
switch is turned to the ON position, have the light
repaired as soon as possible.
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
522 STARTING AND OPERATING

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

WARNING!(Continued)
must never be exploited in a reckless or dangerous
manner, which could jeopardize the user’s safety or
the safety of others.
Hill Start Assist (HSA)
The HSA system is designed to mitigate roll back from a
complete stop while on an incline. If the driver releases
the brake while stopped on an incline, HSA will continue
to hold the brake pressure for a short period. If the driver
does not apply the throttle before this time expires, the
system will release brake pressure and the vehicle will
roll down the hill as normal.
The following conditions must be met in order for HSA to
activate:
•The feature must be enabled.
• The vehicle must be stopped.5

TIRE SAFETY INFORMATION
Tire MarkingsNOTE:
•P (Passenger) — Metric tire sizing is based on U.S.
design standards. P-Metric tires have the letter “P”
molded into the sidewall preceding the size designa-
tion. Example: P215/65R15 95H.
• European — Metric tire sizing is based on European
design standards. Tires designed to this standard have
the tire size molded into the sidewall beginning with
the section width. The letter Pis absent from this tire
size designation. Example: 215/65R15 96H.
• LT (Light Truck) — Metric tire sizing is based on U.S.
design standards. The size designation for LT-Metric
