2012 CHRYSLER 300 SRT ABS

In the event power assist is lost for any reason (for
example, repeated brake applications with the engine
OFF) the brakes will still function. The effort required to
brake the vehicle will be much greater than that required
with the power system operating.
Anti-Lock Brake System
The Anti-Lock Brake System (ABS) provides increased
vehicle stability and brake performance under most
braking conditions. The system automatically “pumps”
the brakes during severe braking conditions to prevent
wheel lock-up.
The electronic brake force distribution (EBD) prevents the
rear wheels from over-braking and provides greater control
of available braking forces applied to the rear axle.
When the vehicle is driven over 7 mph (11 km/h), you
may also hear a slight clicking sound as well as some
related motor noises. These noises are the system per-
forming its self check cycle to ensure that the ABS systemis working properly. This self check occurs each time the
vehicle is started and accelerated past 7 mph (11 km/h).
ABS is activated during braking under certain road or
stopping conditions. ABS-inducing conditions can in-
clude ice, snow, gravel, bumps, railroad tracks, loose
debris, or panic stops.
You also may experience the following when the brake
system goes into Anti-lock:
•The ABS motor running (it may continue to run for a
short time after the stop),
•The clicking sound of solenoid valves,
•Brake pedal pulsations, and
•A slight drop or fall away of the brake pedal at the end
of the stop.
These are all normal characteristics of ABS.
374 STARTING AND OPERATING

WARNING!
•The Anti-Lock Brake System contains sophisticated
electronic equipment that may be susceptible to
interference caused by improperly installed or high
output radio transmitting equipment. This interfer-
ence can cause possible loss of anti-lock braking
capability. Installation of such equipment should be
performed by qualified professionals.
•Pumping of the anti-lock brakes will diminish
their effectiveness and may lead to an accident.
Pumping makes the stopping distance longer. Just
press firmly on your brake pedal when you need
to slow down or stop.(Continued)
WARNING! (Continued)
•The Anti-Lock Brake System (ABS) cannot prevent
the natural laws of physics 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.
•The ABS cannot prevent accidents, 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.
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.5
STARTING AND OPERATING 375

Anti-Lock Brake Light
The “Anti-Lock Brake Light” monitors the anti-
lock brake system. The light will come 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 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 Warning
Light” is not on.
If the “Anti-Lock Brake 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
Light” does not come on when the ignition switch is
turned to the ON position, have the bulb repaired as soon
as possible. If both the “Brake Warning Light” and the “Anti-Lock
Brake Light” remain on, the ABS and EBD systems are
not functioning. Immediate repair to the ABS system is
required.
ELECTRONIC BRAKE CONTROL SYSTEM
Your vehicle is equipped with an advanced electronic
brake control system that include Anti-Lock Brake Sys-
tem (ABS), Traction Control System (TCS), Brake Assist
System (BAS), and the Electronic Stability Control (ESC).
All four of these systems work together to enhance
vehicle stability and control in various driving condi-
tions.
Also, your vehicle is equipped with Hill Start Assist
(HSA), Ready Alert Braking, and Rain Brake Support.
376 STARTING AND OPERATING

Anti-Lock Brake System (ABS)
This system aids the driver in maintaining vehicle control
under adverse braking conditions by controlling hydrau-
lic brake pressure. This prevents wheel lock-up to help
avoid skidding on slippery surfaces during braking.
Refer to “Anti-Lock Brake System” in “Starting and
Operating” for further information.
WARNING!
The ABS cannot prevent the natural laws of physics
from acting on the vehicle, nor can it increase the
traction afforded by prevailing road conditions. The
ABS cannot prevent collisions, including those result-
ing from excessive speed in turns, driving on very
slippery surfaces, 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.
Traction Control System (TCS)
This system monitors the amount of wheel spin of each
driven wheel. 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.
Brake Assist System (BAS)
This system complements the ABS by optimizing the
vehicle braking capability during emergency brake ma-
neuvers. This system detects an emergency braking situ-
ation by sensing the rate and amount of brake application
and then applies optimum pressure to the brakes. This
can help reduce braking distances.
Applying the brakes very quickly results in the best BAS
assistance. To receive the benefits of this system, you
must apply continuous brake pedal pressure during the
stopping sequence. Do not reduce brake pedal pressure
unless braking is no longer desired. Once the brake pedal
is released, the BAS is deactivated.

STARTING AND OPERATING 377

NOTE:
•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 letterPis 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
tires is the same as for P-Metric tires except for the
letters “LT” that are molded into the sidewall preced-
ing the size designation. Example: LT235/85R16.
•Temporary spare tires are spares designed for tempo-
rary emergency use only. Temporary high pressure
compact spare tires have the letter “T” or “S” molded
into the sidewall preceding the size designation. Ex-
ample: T145/80D18 103M.
•High flotation tire sizing is based on U.S. design
standards and it begins with the tire diameter molded
into the sidewall. Example: 31x10.5 R15 LT.

WARNING!
•Do not attempt to seal a tire on the side of the
vehicle closest to traffic. Pull far enough off the
road to avoid the danger of being hit when using
the TIREFIT kit.
•Do not use TIREFIT or drive the vehicle under the
following circumstances:
If the puncture in the tire tread is approximately
1/4 in. (6 mm) or larger.
If the tire has any sidewall damage.
If the tire has any damage from driving with
extremely low tire pressure.
If the tire has any damage from driving on a flat
tire.
If the wheel has any damage.
If you are unsure of the condition of the tire or
the wheel.
(Continued)
WARNING! (Continued)
•Keep TIREFIT away from open flames or heat
source.
•A loose TIREFIT kit thrown forward in a collision
or hard stop could endanger the occupants of the
vehicle. Always stow the TIREFIT kit in the place
provided. Failure to follow these warnings can
result in injuries that are serious or fatal to you,
your passengers, and others around you.
•Take care not to allow the contents of TIREFIT to
come in contact with hair, eyes, or clothing. TIRE-
FIT is harmful if inhaled, swallowed, or absorbed
through the skin. It causes skin, eye, and respira-
tory irritation. Flush immediately with plenty of
water if there is any contact with eyes or skin.
Change clothing as soon as possible, if there is any
contact with clothing.(Continued)

WHAT TO DO IN EMERGENCIES 433

WARNING! (Continued)
•To avoid contamination from foreign matter or
moisture, use only new brake fluid or fluid that
has been in a tightly closed container. Keep the
master cylinder reservoir cap secured at all times.
Brake fluid in a open container absorbs moisture
from the air resulting in a lower boiling point.
This may cause it to boil unexpectedly during hard
or prolonged braking, resulting in sudden brake
failure. This could result in a collision.(Continued)
WARNING! (Continued)
•Overfilling the brake fluid reservoir can result in
spilling brake fluid on hot engine parts, causing
the brake fluid to catch fire. Brake fluid can also
damage painted and vinyl surfaces, care should be
taken to avoid its contact with these surfaces.
•Do not allow petroleum based fluid to contami-
nate the brake fluid. Brake seal components could
be damaged, causing partial or complete brake
failure. This could result in a collision.
Use only brake fluid that has been in a tightly closed
container to avoid contamination from foreign matter or
moisture.
