Chrysler 300 SRT (2014 year). Manual — part 25

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 steer-

ing 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.

CAUTION!

Prolonged operation of the steering system at the end
of the steering wheel travel will increase the steering
fluid temperature and it should be avoided when
possible. Damage to the power steering pump may
occur.

Power Steering Fluid Check

Checking the power steering fluid level at a defined
service interval is not required. The fluid should only be
checked if a leak is suspected, abnormal noises are
apparent, and/or the system is not functioning as antici-
pated. Coordinate inspection efforts through an autho-
rized dealer.

396

STARTING AND OPERATING

CAUTION!

Do not use chemical flushes in your power steering
system as the chemicals can damage your power
steering components. Such damage is not covered by
the New Vehicle Limited Warranty.

WARNING!

Fluid level should be checked on a level surface and
with the engine off to prevent injury from moving
parts and to ensure accurate fluid level reading. Do
not overfill. Use only manufacturer’s recommended
power steering fluid.

If necessary, add fluid to restore to the proper indicated
level. With a clean cloth, wipe any spilled fluid from all
surfaces. Refer to “Fluids, Lubricants, and Genuine
Parts” in “Maintaining Your Vehicle” for further informa-
tion.

FUEL SAVER TECHNOLOGY — IF EQUIPPED

This feature offers improved fuel economy by shutting
off four of the engine’s eight cylinders during light load
and cruise conditions. The system is automatic with no
driver inputs or additional driving skills required.

NOTE:

This system may take some time to return to full

functionality after a battery disconnect.

PARKING BRAKE

Before leaving the vehicle, make sure that the parking
brake is fully applied and place the shift lever in the
PARK position.

The foot operated parking brake is located below the
lower left corner of the instrument panel. To apply the
park brake, firmly push the park brake pedal fully. To
release the parking brake, press the park brake pedal a
second time and let your foot up as you feel the brake
disengage.

5

STARTING AND OPERATING

397

When the parking brake is applied with the ignition
switch in the ON position, the “Brake Warning Light” in
the instrument cluster will illuminate.

NOTE:

• When the parking brake is applied and the transmis-

sion is placed in gear, the “Brake Warning Light” will
flash. If vehicle speed is detected, a chime will sound
to alert the driver. Fully release the parking brake
before attempting to move the vehicle.

• This light only shows that the parking brake is ap-

plied. It does not show the degree of brake application.

When parking on a hill, it is important to turn the front
wheels toward the curb on a downhill grade and away
from the curb on an uphill grade. Apply the parking
brake before placing the shift lever in PARK, otherwise
the load on the transmission locking mechanism may
make it difficult to move the shift lever out of PARK. The
parking brake should always be applied whenever the
driver is not in the vehicle.

Parking Brake

STARTING AND OPERATING

WARNING!

• Never use the PARK position as a substitute for the

parking brake. Always apply the parking brake
fully when parked to guard against vehicle move-
ment and possible injury or damage.

• When leaving the vehicle, always remove the Key

Fob from the ignition and lock your vehicle.

• Never leave children alone in a vehicle, or with

access to an unlocked vehicle. Allowing children to
be in a vehicle unattended is dangerous for a
number of reasons. A child or others could be
seriously or fatally injured. Children should be
warned not to touch the parking brake, brake pedal
or the shift lever.

(Continued)

WARNING! (Continued)

• Do not leave the Key Fob in or near the vehicle (or

in a location accessible to children), and do not
leave the ignition of a vehicle equipped with
Keyless Enter-N-Go™ in the ACC or ON/RUN
mode. 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 a collision.

• Always fully apply the parking brake when leav-

ing your vehicle, or it may roll and cause damage or
injury. Also be certain to leave the transmission in
PARK. Failure to do so may allow the vehicle to roll
and cause damage or injury.

CAUTION!

If the “Brake Warning Light” remains on with the
parking brake released, a brake system malfunction
is indicated. Have the brake system serviced by an
authorized dealer immediately.

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.
• A slight drop or fall away of the brake pedal at the end

of the stop.

These are all normal characteristics of ABS.

400

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 a collision.
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 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.

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.

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 may be equipped with Hill Start Assist
(HSA), Ready Alert Braking, and Rain Brake Support.

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 re-
sulting from excessive speed in turns, driving on
very slippery surfaces, or hydroplaning. The capa-
bilities 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.

402

STARTING AND OPERATING

A feature of the TCS system, Brake Lock Differential
(BLD), controls the wheel spin across a driven axle. If one
wheel on a driven axle is spinning faster than the other,
the system will apply the brake of the spinning wheel.
This will allow more engine torque to be applied to the
wheel that is not spinning. This feature remains active
even if TCS and ESC are in the “Partial Off” mode. Refer
to “Electronic Stability Control (ESC)” in this section for
more information.

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 collisions, including those re-
sulting from excessive speed in turns, driving on
very slippery surfaces, or hydroplaning. The capa-
bilities 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.

5

STARTING AND OPERATING

403

Electronic Stability Control (ESC)

This system enhances directional control and stability of
the vehicle under various driving conditions. The ESC
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 ESC 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 ESC 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.

WARNING!

The Electronic Stability Control System (ESC) cannot
prevent the natural laws of physics from acting on
the vehicle, nor can it increase the traction afforded
by prevailing road conditions. ESC cannot prevent
all accidents, including those resulting from exces-
sive speed in turns, driving on very slippery surfaces,
or hydroplaning. ESC also cannot prevent accidents
resulting from loss of vehicle control due to inappro-
priate driver input for the conditions. Only a safe,
attentive, and skillful driver can prevent accidents.
The capabilities of an ESC equipped vehicle must
never be exploited in a reckless or dangerous manner
which could jeopardize the user’s safety or the safety
of others.

404

STARTING AND OPERATING

ESC Operating Modes

The ESC system has three available operating modes:

ESC On

This is the normal operating mode for the ESC. When-
ever the vehicle is started, the ESC system will be in this
mode. This mode should be used for most driving
situations. The ESC should only be turned OFF for
specific reasons as noted in the following paragraphs.

Partial Off

The “Partial Off” mode is intended for times when a
more spirited driving experience is desired. It is also
intended for driving in deep snow, sand, or gravel. This
mode disables the TCS portion of the ESC and raises the
threshold for ESC activation, which allows for more
wheel spin than what ESC normally allows.

The “ESC Off” switch is located in the switch bank near
the bottom center of the instrument panel. To enter the
“Partial Off” mode, momentarily press the “ESC Off”
switch and the “ESC Activation/Malfunction Indicator
Light” will illuminate. To turn the ESC ON again, mo-
mentarily press the “ESC Off” switch and the “ESC
Activation/Malfunction Indicator Light” will turn off.

NOTE:

To improve the vehicle’s traction when driving

with snow chains, or when starting off in deep snow,
sand, or gravel, it may be desirable to switch to the
“Partial Off” mode by momentarily pressing the “ESC
Off” switch. Once the situation requiring “Partial Off”
mode is overcome, turn the ESC ON again by momen-
tarily pressing the “ESC Off” switch. This may be done
while the vehicle is in motion.

5

STARTING AND OPERATING

405

WARNING!

• When in “Partial Off” mode, the TCS functionality

of ESC, (except for the limited slip feature de-
scribed in the TCS section), has been disabled and
the “ESC Off Indicator Light” will be illuminated.
When in “Partial Off” mode, the engine power
reduction feature of TCS is disabled, and the
enhanced vehicle stability offered by the ESC sys-
tem is reduced.

Full Off

This mode is intended for off-highway or off-road use
only and should not be used on any public roadways. In
this mode, all TCS and ESC stability features are turned
OFF. To enter the “Full Off” mode, press and hold the
“ESC Off” switch for five seconds while the vehicle is
stopped with the engine running. After five seconds, a

chime will sound, the “ESC Activation/Malfunction In-
dicator Light” will illuminate, and the

⬙ESC OFF⬙ mes-

sage will display in the vehicle odometer. Press and
release the TRIP ODOMETER button located on the
instrument cluster to clear this message. The “ESC OFF”
message may appear in the Electronic Vehicle Informa-
tion Center (EVIC). Refer to “Electronic Vehicle Informa-
tion Center (EVIC)” in “Understanding Your Instrument
Panel” for further information. To turn ESC ON again,
momentarily press the “ESC Off” switch.

NOTE:

The

⬙ESC OFF⬙ message will display and the

audible chime will sound when the shift lever is moved
into the PARK position from any position other than
PARK and then moved out of the PARK position. This
will occur when the message was previously cleared.

406

STARTING AND OPERATING

WARNING!

In the ESC “Full Off” mode, the engine torque
reduction and stability features are disabled. There-
fore, the enhanced vehicle stability offered by ESC is
unavailable. In an emergency evasive maneuver, the
ESC system will not engage to assist in maintaining
stability.

ⴖESC Offⴖ mode is intended for off-highway

or off-road use only.

NOTE:

When the ESC is switched OFF, 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 and
allow more engine torque to be applied to the wheel that is
not spinning. To improve the vehicle’s traction when
driving with tire chains, or when starting off in deep snow,
sand, or gravel, it may be desirable to switch to the “Partial
Off” mode by momentarily pressing the “ESC Off” switch.

Hill Start Assist (HSA)

The HSA system is designed to assist the driver when
starting a vehicle from a stop on a hill. HSA will maintain
the level of brake pressure the driver applied for a short
period of time after the driver takes their foot off of the
brake pedal. If the driver does not apply the throttle
during this short period of time, the system will release
brake pressure and the vehicle will roll down the hill. The
system will release brake pressure in proportion to the
amount of throttle applied as the vehicle starts to move in
the intended direction of travel.

HSA Activation Criteria

The following criteria must be met in order for HSA to
activate:

• Vehicle must be stopped.
• Vehicle must be on a 6% (approximate) grade or

greater hill.

5

STARTING AND OPERATING

407

• Gear selection matches vehicle uphill direction (i.e.,

vehicle facing uphill is in forward gear; vehicle back-
ing uphill is in REVERSE gear).

HSA will work in REVERSE and all forward gears when
the activation criteria have been met. The system will not
activate if the vehicle is placed in NEUTRAL or PARK.

WARNING!

There may be situations on minor hills with a loaded
vehicle, or while pulling a trailer, when the system
will not activate and slight rolling may occur. This
could cause a collision with another vehicle or object.
Always remember the driver is responsible for brak-
ing the vehicle.

Towing With HSA

HSA will provide assistance when starting on a grade
when pulling a trailer.

WARNING!

• HSA is not a parking brake. Always apply the

parking brake fully when leaving your vehicle.
Also, be certain to leave the transmission in PARK.

• Failure to follow these warnings may cause the

vehicle to roll down the incline and could collide
with another vehicle, object or person, and cause
serious or fatal injury. Always remember to use the
parking brake while parking on a hill and that the
driver is responsible for braking the vehicle.

408

STARTING AND OPERATING

HSA Off

If you wish to turn off the HSA system, it can be done
using the Customer Programmable Features in the Elec-
tronic Vehicle Information Center (EVIC). Refer to “Elec-
tronic Vehicle Information Center (EVIC)” in “Under-
standing Your Instrument Panel” for further information.

Ready Alert Braking

Ready Alert Braking may reduce the time required to
reach full braking during emergency braking situations.
It anticipates when an emergency braking situation may
occur by monitoring how fast the throttle is released by
the driver. When the throttle is released very quickly,
Ready Alert Braking applies a small amount of brake

pressure. This brake pressure will not be noticed by the
driver. The brake system uses this brake pressure to allow
a fast brake response if the driver applies the brakes.

Rain Brake Support

Rain Brake Support may improve braking performance
in wet conditions. It will periodically apply a small
amount of brake pressure to remove any water buildup
on the front brake rotors. It only functions when the
windshield wipers are in the LO or HI mode, it does not
function in the intermittent mode. When Rain Brake
Support is active, there is no notification to the driver and
no driver interaction is required.

STARTING AND OPERATING

409

ESC Activation/Malfunction Indicator Light And
ESC OFF Indicator Light

The “ESC Activation/Malfunction Indicator
Light” in the instrument cluster will come on
when the ignition switch is cycled to the ON/
RUN position. It should go out with the engine

running. If the “ESC Activation/Malfunction Indicator
Light” comes on continuously with the engine running, a
malfunction has been detected in the ESC system. If this
light remains on after several ignition cycles, and the
vehicle has been driven several miles (kilometers) at
speeds greater than 30 mph (48 km/h), see your autho-
rized dealer as soon as possible to have the problem
diagnosed and corrected.

The “ESC Activation/Malfunction Indicator Light” (lo-
cated in the instrument cluster) starts to flash as soon as
the tires lose traction and the ESC system becomes active.
The “ESC Activation/Malfunction Indicator Light” also
flashes when TCS is active. If the “ESC Activation/
Malfunction Indicator Light” begins to flash during ac-
celeration, 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.

NOTE:

• The “ESC Off Indicator Light” and the “ESC

Activation/Malfunction Indicator Light” come on mo-
mentarily each time the ignition switch is turned to the
ON/RUN position.

410

STARTING AND OPERATING

• Each time the ignition is cycled to the ON/RUN

position, the ESC system will be ON even if it was
cycled off previously.

• The ESC system will make buzzing or clicking sounds

when it is active. This is normal; the sounds will stop
when ESC becomes inactive following the maneuver
that caused the ESC activation.

The “ESC OFF Indicator Light” indicates the
Electronic Stability Control (ESC) is partially
off or full off.

Synchronizing ESC

If the power supply is interrupted (battery
disconnected

or

discharged),

the

“ESC

Activation/Malfunction Indicator 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 “ESC Activation/
Malfunction Indicator Light” should go out. However, if
the light remains on, have the ESC and BAS checked at
your authorized dealer as soon as possible.
