brake CHRYSLER 300 C 2008 1.G Service Manual

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 equip-
ment. This interference 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 effective-
ness 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.
•Anti-lock 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. Only a safe, attentive, and skillful
driver can prevent accidents.
•The capabilities of an ABS equipped vehicle must never be
exploited in a reckless or dangerous manner, which could jeop-
ardize 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.
Anti-Lock Brake Light
The ABS light monitors the Anti-Lock Brake Sys-
tem. 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 ABS 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 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 come on when the
Ignition switch is turned to the ON position, have the
bulb repaired as soon as possible.
326 STARTING AND OPERATING

If both the Brake Warning Light and the ABS Light
remain on, the Anti-Lock brakes (ABS) and Electronic
Brake Force Distribution (EBD) systems are not function-
ing. Immediate repair to the ABS system is required.
POWER STEERING
The standard power steering system will give you good
vehicle response and increased ease of maneuverability
in tight spaces. The system will provide mechanical
steering capability if power assist is lost.
If for some reason the power assist is interrupted, it will
still be possible to steer your vehicle. Under these condi-
tions, you will observe a substantial increase in steering
effort, especially at very low vehicle speeds and during
parking maneuvers.NOTE:Increased noise levels at the end of the steering
wheel travel are considered normal and do not indicate
that there is a problem with the power steering system.
Upon initial start-up in cold weather, the power steering
pump may make noise for a short amount of time. This is
due to the cold, thick fluid in the steering system. This
noise should be considered normal, and it does not in any
way damage the steering system.
WARNING!
Continued operation with reduced power steering
assist could pose a safety risk to yourself and others.
Service should be obtained as soon as possible.

The TCS 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.
The ESP/TCS indicator light, located in the
instrument cluster, starts to flash as soon as the
tires lose traction and the ESP system becomes
active. The indicator light also flashes when the
TCS is active. If the indicator light begins to flash during
acceleration, ease up on the accelerator and apply as little
throttle as possible. Be sure to adapt your speed and
driving to the prevailing road conditions.
When the TCS is switched off, the torque reduction
feature is cancelled. However, a feature of the system
remains active. This feature controls wheel spin across an
axle quite similarly to a limited slip differential. If one
wheel on an axle is spinning faster than the other, the
system will apply the brake of the spinning wheel andallow more engine torque to be applied to the wheel that
is not spinning. This wheel slip control is active up to 50
mph (80 km/h).
CAUTION!
When the ESP/TCS indicator light is illuminated
continuously, the ESP is switched off. Avoid spin-
ning one drive wheel. This may cause serious dam-
age to the drive train.
NOTE:
•The Traction Control System comes on each time the
ignition switch is turned ON. This will occur even if
you used the ESP OFF button to turn OFF the system.
•The Traction Control System will make buzzing or
clicking sounds when in operation.

instructions.
BRAKE ASSIST SYSTEM (BAS) — IF EQUIPPED
WARNING!
The BAS (Brake Assist System) cannot prevent the
natural laws of physics from acting on the vehicle,
nor can it increase the traction afforded by prevailing
road conditions. The BAS cannot prevent accidents,
including those resulting from excessive speed in
turns, driving on very slippery surfaces, or hydro-
planing. Only a safe, attentive, and skillful driver can
prevent accidents. The capabilities of a BAS-
equipped vehicle must never be exploited in a reck-
less or dangerous manner, which could jeopardize
the user’s safety or the safety of others.The Brake Assist System (BAS) is standard on vehicles
equipped with Electronic Stability Program (ESP). The
BAS is designed to optimize the vehicle’s braking capa-
bility during emergency braking maneuvers. The system
applies optimum pressure to the brakes in emergency
braking conditions that might otherwise be afforded
solely by the driver’s braking style. 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 braking power
during the stopping sequence. Do not reduce brake pedal
pressure. Once the brake pedal is released, the BAS is
deactivated.

ELECTRONIC STABILITY PROGRAM (ESP) —
IF EQUIPPED
WARNING!
The ESP (Electronic Stability Program) cannot pre-
vent the natural laws of physics from acting on the
vehicle, nor can it increase the traction afforded by
prevailing road conditions. The ESP cannot prevent
accidents, including those resulting from excessive
speed in turns, driving on very slippery surfaces, or
hydroplaning. Only a safe, attentive, and skillful
driver can prevent accidents. The capabilities of an
ESP-equipped vehicle must never be exploited in a
reckless or dangerous manner, which could jeopar-
dize the user’s safety or the safety of others.This system enhances directional control and stability of
the vehicle under various driving conditions. The ESP
corrects for oversteering and understeering the vehicle
by applying the brake of the appropriate wheel. Engine
power may also be reduced to assist in counteracting the
condition of oversteer or understeer and help the vehicle
maintain the desired path.
The ESP uses sensors in the vehicle to determine the path
that the driver intends to steer the vehicle and compares
it to the actual path of the vehicle. When the actual path
does not match the intended path, the ESP applies the
brake of the appropriate wheel to assist in counteracting
the condition of oversteer or understeer.
•Oversteer - when the vehicle is turning more than
appropriate for the steering wheel position.
•Understeer - when the vehicle is turning less than
appropriate for the steering wheel position.

CAUTION!
When the ESP/TCS indicator light is illuminated
continuously, the ESP is switched off. Avoid spin-
ning one drive wheel. This may cause serious dam-
age to the drive train.
CAUTION!
If the vehicle is towed with the front axle raised, the
engine must be shut off (key in the ignition switch to
the LOCK or ACC position). Otherwise, the ESP will
immediately be engaged and it will apply the rear
wheel brakes.
Synchronizing ESP
The malfunction indicator light for the ESP is
combined with BAS indicator. If the power
supply is interrupted (battery disconnected or
discharged), the ESP/BAS malfunction indica-
tor light may illuminate with the engine running. If this
should occur, turn the steering wheel completely to the
left and then to the right. The ESP/BAS malfunction
indicator light should go out. However, if the light
remains on, have the ESP and BAS checked at your
authorized dealer as soon as possible.

Loading
To load your vehicle properly, first figure out its empty
weight, axle by axle and side by side. Store heavier items
down low and be sure you distribute their weight as
evenly as possible. Stow all loose items securely before
driving. If weighing the loaded vehicle shows that you
have exceeded either GAWR, but the total load is within
the specified GVWR, you must redistribute the weight.
Improper weight distribution can have an adverse effect
on the way your vehicle steers and handles and the way
the brakes operate.A loaded vehicle is shown in the illustration. Note that
neither the GVWR nor the GAWR capacities have been
exceeded.

Frontal Area
Frontal area is the maximum height and maximum width
of the front of a trailer.
Trailer Sway Control
The trailer sway control is a telescoping link that can be
installed between the hitch receiver and the trailer tongue
that typically provides adjustable friction associated with
the telescoping motion to dampen any unwanted trailer
swaying motions while traveling.
Weight-Carrying Hitch
A weight-carrying hitch supports the trailer tongue
weight, just as if it were luggage located at a hitch ball or
some other connecting point of the vehicle. These kinds
of hitches are the most popular on the market today and
they are commonly used to tow small- and medium-
sized trailers.
Weight-Distributing Hitch
A weight-distributing system works by applying lever-
age through spring (load) bars. They are typically used
for heavier loads, to distribute trailer tongue weight to
the tow vehicle’s front axle and the trailer axle(s). When
used in accordance with the manufacturers’ directions, it
provides for a more level ride, offering more consistent
steering and brake control thereby enhancing towing
safety. The addition of a friction / hydraulic sway control
also dampens sway caused by traffic and crosswinds and
contributes positively to tow vehicle and trailer stability.
Trailer sway control and a weight distributing (load
equalizing) hitch are recommended for heavier Tongue
Weights (TW) and may be required depending on Vehicle
and Trailer configuration / loading to comply with Gross
Axle Weight Rating (GAWR) requirements.

WARNING!
•An improperly adjusted Weight Distributing
Hitch system may reduce handling, stability, brak-
ing performance, and could result in an accident.
•Weight Distributing Systems may not be compat-
ible with Surge Brake Couplers. Consult with your
hitch and trailer manufacturer or a reputable Rec-
reational Vehicle dealer for additional
information.

Towing Requirements
To promote proper break-in of your new vehicle driv-
etrain components the following guidelines are recom-
mended:
CAUTION!
•Avoid towing a trailer for the first 500 miles (805
km) of vehicle operation. Doing so may damage
your vehicle.
•During the first 500 miles (805 km) of trailer
towing, limit your speed to 50 mph (80 km/h).
Perform the maintenance listed in Section 8 of this
manual. When towing a trailer, never exceed the GAWR,
or GCWR, ratings.
WARNING!
Improper towing can lead to an injury accident.
Follow these guidelines to make your trailer towing
as safe as possible:
Make certain that the load is secured in the trailer
and it will not shift during travel. When trailering
cargo that is not fully secured, dynamic load shifts
can occur that may be difficult for the driver to
control. You could lose control of your vehicle and
have an accident.
•When hauling cargo, or towing a trailer, do not
overload your vehicle or trailer. Overloading can cause
a loss of control, poor performance, or damage to
brakes, axle, engine, transmission, steering, suspen-
sion, chassis structure, or tires.
