2010 CHRYSLER 300 brakes

•If the transmission temperature gets too hot, the
transmission may downshift out of Overdrive or en-
gage Overdrive at higher vehicle speeds until the
transmission cools down. After cooldown, Overdrive
will resume normal operation.
“3” (Third)
This range eliminates shifts into Overdrive. The transmis-
sion will operate normally in 1st, 2nd, and 3rd while in
this range. The “3” position should also be used when
descending steep grades to prevent brake system dis-
tress.
NOTE:Using the “3” range while operating the vehicle
under heavy operating conditions will improve perfor-
mance and extend transmission life by reducing exces-
sive shifting and heat buildup.
“L” (Low)
This range should be used for engine braking when
descending very steep grades. In this range, upshifts will occur only to prevent engine overspeed while downshifts
occur earlier than in other gear range selections.
CAUTION!
Never race the engine with the brakes on and the
vehicle in gear, and never hold the vehicle on an
incline without applying the brakes. These practices
can cause overheating and damage to the transmis-
sion.
Torque Converter Clutch
A feature designed to improve fuel economy has been
added to the automatic transmission in this vehicle. A
clutch within the torque converter engages automatically
at calibrated speeds. This may result in a slightly differ-
ent feeling or response during normal operation in high
gear. When the vehicle speed drops or during accelera-
tion, the clutch automatically and smoothly disengages.

CAUTION! (Continued)
•Driving through standing water may cause dam-
age to your vehicle’s drivetrain components. Al-
ways inspect your vehicle’s fluids (i.e., engine oil,
transmission, axle, etc.) for signs of contamination
(i.e., fluid that is milky or foamy in appearance)
after driving through standing water. Do not con-
tinue to operate the vehicle if any fluid appears
contaminated, as this may result in further dam-
age. Such damage is not covered by the New
Vehicle Limited Warranty.
•Getting water inside your vehicle’s engine can
cause it to lock up and stall out, and cause serious
internal damage to the engine. Such damage is not
covered by the New Vehicle Limited Warranty.
WARNING!
•Driving through standing water limits your vehi-
cle’s traction capabilities. Do not exceed 5 mph
(8 km/h) when driving through standing water.
•Driving through standing water limits your vehi-
cle’s braking capabilities, which increases stop-
ping distances. Therefore, after driving through
standing water, drive slowly and lightly press on
the brake pedal several times to dry the brakes.
•Getting water inside your vehicle’s engine can
cause it to lock up and stall out, and leave you
stranded.
•Failure to follow these warnings may result in
injuries that are serious or fatal to you, your
passengers, and others around you.

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 is
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.
338 STARTING AND OPERATING

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 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 ABS cannot prevent the natural laws of phys-
ics from acting on the vehicle, nor can it increase
braking or steering efficiency beyond that af-
forded 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 hydro-
planing. 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 that 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.

STARTING AND OPERATING 339

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.WARNING!
The BAS 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 re-
sulting 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 a BAS-equipped vehicle must
never be exploited in a reckless or dangerous manner
that could jeopardize the user’s safety or the safety of
others.
Electronic Stability Program (ESP)
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

Overloading
The load carrying components (axle, springs, tires,
wheels, etc.) of your vehicle will provide satisfactory
service as long as you do not exceed the GVWR and the
front and rear GAWR.
The best way to figure out the total weight of your
vehicle is to weigh it when it is fully loaded and ready for
operation. Weigh it on a commercial scale to ensure that
it is not over the GVWR.
Figure out the weight on the front and rear of the vehicle
separately. It is important that you distribute the load
evenly over the front and rear axles.
Overloading can cause potential safety hazards and
shorten useful service life. Heavier axles or suspension
components do not necessarily increase the vehicle’s
GVWR.
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.
NOTE:
•Refer to the “Vehicle Certification Label” affixed to the
rear of the driver’s door for your vehicle’s GVWR and
GAWRs.
•Refer to the “Tire Placard” for your vehicle’s proper
tire pressure.

CAUTION! (Continued)
•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.
WARNING!
Improper towing can lead to an injury accident.
Follow these guidelines to make your trailer towing
as safe as possible:(Continued)
WARNING! (Continued)
•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 dam-
age to brakes, axle, engine, transmission, steering,
suspension, chassis structure, or tires.
•Safety chains must always be used between your
vehicle and trailer. Always connect the chains to
the frame or hook retainers of the vehicle hitch.
Cross the chains under the trailer tongue and
allow enough slack for turning corners.(Continued)
390 STARTING AND OPERATING

Check for signs of tire wear or visible tire damage
before towing a trailer. Refer to “Tires – General
Information” in “Starting and Operating” for informa-
tion on tread wear indicators and for the proper
inspection procedure.
When replacing tires, refer to “Tires – General Infor-
mation” in “Starting and Operating” for information
on replacement tires and for the proper tire replace-
ment procedures. Replacing tires with a higher load
carrying capacity will not increase the vehicle’s GVWR
and GAWR limits.
Towing Requirements – Trailer Brakes

Donot interconnect the hydraulic brake system or
vacuum system of your vehicle with that of the trailer.
This could cause inadequate braking and possible
personal injury.
An electronically actuated trailer brake controller is
required when towing a trailer with electronically
actuated brakes. When towing a trailer equipped with
a hydraulic surge actuated brake system, an electronic
brake controller is not required.
Trailer brakes are recommended for trailers over
1,000 lbs (454 kg) and required for trailers in excess of
2,000 lbs (907 kg).
CAUTION!
If the trailer weighs more than 1,000 lbs (454 kg)
loaded, it should have its own brakes, and they
should be of adequate capacity. Failure to do this
could lead to accelerated brake lining wear, higher
brake pedal effort, and longer stopping distances.
