2004 CHRYSLER 300 M brakes

If the ABS light is on, the brake system should be serviced
as soon as possible to restore the benefits of Anti-Lock
brakes.
23. Brake System Warning Light
The dual brake system provides a reserve
braking capability if a failure occurs in a
portion of the hydraulic system.
This light monitors both the brake fluid level and the
parking brake. If the light comes on, it indicates either
that the parking brake is on or there is a low fluid level in
the brake master cylinder. On vehicles equipped with
anti-lock brakes (ABS), the brake light may also indicate
reduced braking performance. If the parking brake is off
and the light remains on, have the brake system in-
spected as soon as possible.
The light will also come on when the parking brake is
applied with the ignition in the RUN position.The warning light should be checked frequently to assure
that it is operating properly. This can be done by turning
the ignition switch to START. The light should come on.
If the red brake light does not come on, have the system
checked by an authorized dealer.
WARNING!
Driving a vehicle with the brake light on is danger-
ous. Part of the brake system may have failed. It will
take longer to stop the vehicle. You could have an
accident. Have the vehicle checked immediately.
NOTE:This light shows only that the parking brake is
on. It does not show the degree of brake application.
In an ABS equipped vehicle, the Brake System Warning
light will come on if the ABS light is not functioning or if
the ABS system is not communicating.

STARTING PROCEDURES
WARNING!
Do not leave children or animals inside parked
vehicles in hot weather. Interior heat build up may
cause serious injury or death.
The gear selector must be in the NEUTRAL or PARK
position before you can start the engine. Apply the brakes
before shifting to any driving gear.
Normal Starting
Normal Starting of either a cold or a warm engine does
not require pumping or depressing the accelerator pedal.
Simply turn the key to the “START” position and release
when the engine starts. If the engine has not started
within 3 seconds, slightly depress the accelerator pedal
while continuing to crank. If the engine fails to start
within 15 seconds, turn the key to the “OFF” position,
wait 10 to 15 seconds, then repeat the normal starting
procedure.
Extremely Cold Weather (below -20°F or -29°C)
For reliable starting at these temperatures, use externally
powered battery and electric engine block heaters that
are available from your dealer.

WARNING!
•Leaving children in a vehicle unattended is dan-
gerous for several reasons. A child or others could
be injured. Children should be warned not to
touch the parking brake or the gear selector. Don’t
leave the keys in the ignition. 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 an accident.
BRAKE SYSTEM
Your vehicle is equipped with power brakes as standard
equipment. In the event you lose power assist 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 substantially in-
creased over that required with the power system oper-
ating.
If either of the two hydraulic systems lose normal capa-
bility, the remaining system will still function with some
loss of overall braking effectiveness. This will be evident
by increased pedal travel during application, greater
pedal force required to slow or stop, and activation of the
Brake Warning Lamp during brake use.
162 STARTING AND OPERATING

Anti-Lock Brake System (ABS)
The ABS gives 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.
All vehicle wheels and tires must be the same size and
tires must be properly inflated to produce accurate
signals for the ABS computer. However, the system will
compensate when the compact spare is in use.
During stops where ABS is activated, a vibration of the
brake pedal may be felt and associated system noises
may be heard.
WARNING!
Pumping of the brake pedal will diminish the effec-
tiveness of Anti-lock brakes 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.
POWER STEERING
Your vehicle is equipped with power assisted steering as
standard equipment. The power assisted steering system
of your vehicle provides mechanical steering capability
in the event power assist is lost.
If for some reason the hydraulic pressure is interrupted,
it will still be possible to steer your vehicle. Under these
conditions you will observe a substantial increase in
steering effort.
TRACTION CONTROL
The Traction Control System reduces wheel slip and
maintains traction at the driving (front) wheels. The
system reduces wheel slip by engaging the brake on the
wheel that is losing traction while spinning. The traction
system operates at speeds below 35 mph (56 km/h).
The system is always in the “stand by” mode unless:
•The Traction Control switch has been used to turn the
system off;
•There is a Anti-Lock Brake System malfunction;
•There is a Traction Control System malfunction;

adequate performance. For Example, choose “4” if the
desired speed can be maintained. Choose “3” or “2” if
needed to maintain the desired speed.
Extended driving at high RPM’s should be avoided to
prevent excess heat generation. A reduction in vehicle
speed may be necessary to avoid extended driving at
high RPMs. Return to a higher gear range or vehicle
speed when road conditions and RPM level allow.
•
The trailer tongue load must be considered as part of
the tow vehicle load capacity when loading the ve-
hicle.
•If the trailer weighs more than 1,000 lbs. (450 kg), it
should have its own brakes.
WARNING!
Connecting trailer brakes to your vehicle’s hydraulic
brake lines can overload your brake system and
cause it to fail. You might not have brakes when you
need them and could have an accident.
•Whenever you pull a trailer, regardless of the trailer
size, stop lights and turn signals on the trailer are
recommended for motoring safety.
•The automatic transmission fluid, filter, and hypoid
differential fluid should be changed per Maintenance
Schedule “B” if you tow a trailer.
•If your Engine Coolant Light comes on, see the para-
graph on Overheating in Section 6 of this manual.
NOTE:Check the automatic transmission fluid level
before all towing. Fluid discoloration, or a burnt odor,
shows the need for a transmission fluid and filter change.

•Maintain a coolant concentration of a minimum of 50%
ethylene glycol and high quality water with recom-
mended antifreeze for proper corrosion protection of
your engine cooling system that contains aluminum
components.
•Make sure that the radiator and coolant bottle hoses
are not kinked or obstructed.
•Keep the front of the radiator and air conditioning
condenser clean.
•Do not change the thermostat for summer or winter
operation. If replacement is ever necessary, install
ONLY the correct type thermostat. Other designs may
result in unsatisfactory engine cooling performance,
poor gas mileage, and increased emissions.
Hoses and Vacuum/Vapor Harnesses
Inspect surfaces of hoses and nylon tubing for evidence
of heat and mechanical damage. Hard or soft spots,
brittle rubber, cracking, checking, tears, cuts, abrasions,
and excessive swelling indicate deterioration of the rub-
ber.Pay particular attention to those hoses nearest to high
heat sources such as the exhaust manifold. Inspect hose
routing to be sure hoses do not touch any heat source or
moving component that may cause heat damage or
mechanical wear.
Insure nylon tubing in these areas has not melted or
collapsed. Inspect all hose connections such as clamps
and couplings to make sure they are secure and no leaks
are present. Components should be replaced immedi-
ately if there is any evidence of degradation that could
cause failure.
Brakes
In order to assure brake system performance, all brake
system components should be inspected periodically.
Suggested service intervals can be found in Section 8,
Maintenance Schedules.
218 MAINTAINING YOUR VEHICLE

WARNING!
Riding the brakes can lead to brake failure and
possibly an accident. Driving with your foot resting
or riding on the brake pedal can result in abnormally
high brake temperatures, excessive lining wear, and
possible brake damage. You wouldn’t have your full
braking capacity in an emergency.
Brake and Power Steering System Hoses
When servicing the vehicle for scheduled maintenance,
inspect surface of hoses for evidence of heat and me-
chanical damage. Hard and brittle rubber, cracking,
checking, tears, cuts, abrasion, and excessive swelling
suggest deterioration of the rubber. Particular attention
should be made to examining those hose surfaces nearest
to high heat sources, such as the exhaust manifold.
Inspect all hose clamps and couplings to make sure they
are secure and no leaks are present.
NOTE:Often, fluids such as oil, power steering fluid,
and brake fluid are used during assembly plant opera-
tions to ease the assembly of hoses to couplings. There-
fore, oil wetness at the hose-coupling area is not neces-
sarily an indication of leakage. Actual dripping of hot
fluid when systems are under pressure (during vehicle
operation) should be noted before hose is replaced based
on leakage.
NOTE:Inspection of brake hoses should be done
whenever the brake system is serviced and every engine
oil change.
WARNING!
Worn brake hoses can burst and cause brake failure.
You could have an accident. If you see any signs of
cracking, scuffing, or worn spots, have the brake
hoses replaced immediately.
Brake Master CylinderThe fluid level in the master cylinder should be checked
when performing under hood services, or immediately if
the brake system warning lamp shows system failure.
