engine CHRYSLER 300 2015 2.G Repair Manual

•If AutoStick is engaged while the transmission gear
selector is in the SPORT position, manual gear selec-
tion will be maintained until the gear selector is
returned to DRIVE, or as described below. The trans-
mission will not upshift automatically at redline in this
mode, nor will downshifts be obtained if the accelera-
tor pedal is pressed to the floor.
•In either DRIVE or SPORT mode, the transmission will
automatically downshift as the vehicle slows (to pre-
vent engine lugging) and will display the current gear.
•The transmission will automatically downshift to first
gear when coming to a stop. After a stop, the driver
should manually upshift (+) the transmission as the
vehicle is accelerated.
•You can start out, from a stop, in first or second gear.
Tapping (+) at a stop will allow starting in second gear.
Starting out in second gear can be helpful in snowy or
icy conditions.
•If a requested downshift would cause the engine to
over-speed, that shift will not occur.
•The system will ignore attempts to upshift at too low
of a vehicle speed.
•Holding the (-) paddle depressed will downshift the
transmission to the lowest gear possible at the current
speed.
•Transmission shifting will be more noticeable when
AutoStick is engaged.
•The system may revert to automatic shift mode if a
fault or overheat condition is detected.
To disengage AutoStick mode, press and hold the (+)
shift paddle until#D#or#S#is once again indicated in the
instrument cluster. Shifting out of SPORT mode will also
disable AutoStick. You can shift in or out of AutoStick
mode at any time without taking your foot off the
accelerator pedal.
354 STARTING AND OPERATING

WARNING!
Do not downshift for additional engine braking on a
slippery surface. The drive wheels could lose their
grip and the vehicle could skid, causing a collision or
personal injury.
ALL-WHEEL DRIVE (AWD) — IF EQUIPPED
This vehicle is equipped with an active on-demand
All-Wheel Drive (AWD) system which makes available
optimum traction for a wide variety of road surface and
driving conditions. The system minimizes wheel slip by
automatically redirecting torque to the front and rear
wheels as necessary.
To maximize fuel economy, your AWD vehicle automati-
cally defaults to rear-wheel drive (RWD) when road and
environmental conditions are such that wheel slip is
unlikely to occur. When specific road and environmental
conditions require increased levels of road traction, the
vehicle automatically shifts into AWD mode. Automatic
AWD operation could be activated by outside tempera-
ture, wheel slip, or other predetermined conditions (there
may be a slight delay for AWD engagement after a wheel
slip condition occurs). AWD can also be manually se-
lected by activating AutoStick mode (+/-), engaging
Sport Mode or activating the windshield wipers for an
extended period of time. Drive mode, RWD or AWD, can
be found in the Driver Information Display (DID). Refer
to “Driver Information Display (DID)” in “Understand-
ing Your Instrument Panel” for further information.
NOTE:If the “SERVICE AWD SYSTEM” warning mes-
sage appears after engine start up, or during driving, it
means that the AWD system is not functioning properly
and that service is required. Refer to “Driver Information
Display (DID)” in “Understanding Your Instrument
Panel” for further information.

CAUTION!(Continued)
•Driving through standing water may cause damage
to your vehicle’s drivetrain components. Always
inspect your vehicle’s fluids (i.e., engine oil, trans-
mission, axle, etc.) for signs of contamination (i.e.,
fluid that is milky or foamy in appearance) after
driving through standing water. Do not continue to
operate the vehicle if any fluid appears contami-
nated, as this may result in further damage. 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.
ELECTRIC POWER STEERING
The electric power steering system will give you good
vehicle response and increased ease of maneuverability
in tight spaces. The system will vary its assist to provide
light efforts while parking and good feel while driving. If
the electric steering system experiences a fault that
prevents it from providing assist, you will still have the
ability to steer the vehicle manually.
Alternate electric power steering efforts can be selected
through the Uconnect® System. Refer to ”Customer
Programmable Features” or “Performance Control — If
Equipped” within “Uconnect® Settings” in “Under-
standing Your Instrument Panel” for further information.

STARTING AND OPERATING 359

WARNING!
Continued operation with reduced assist could pose
a safety risk to yourself and others. Service should be
obtained as soon as possible.
If the Steering icon is displayed and the “SER-
VICE POWER STEERING” or the “POWER
STEERING ASSIST OFF – SERVICE SYSTEM”
message is displayed within the Driver Infor-
mation Display (DID), this indicates the vehicle needs to
be taken to the dealer for service. Refer to “Driver
Information Display (DID)” in “Understanding Your
Instrument Panel” for further information.
NOTE:
•Even if the power steering assistance is no longer
operational, it is still possible to steer the vehicle.
Under these conditions there will be a substantial
increase in steering effort, especially at low speeds and
during parking maneuvers.
•If the condition persists, see your authorized dealer for
service.
FUEL SAVER TECHNOLOGY 5.7L ENGINE ONLY
— 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.
360 STARTING AND OPERATING

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.
NOTE:Your vehicle is equipped with a high perfor-
mance braking system. The brake pads are a semi-
metallic compound, which offer superior fade resistance
for consistent operation. A compromise to using this type
of brake pad is that the brakes may produce more brake
dust and may squeal slightly under certain weather and
operating conditions (i.e., during light brake applica-
tions) this is considered normal conditions.
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)
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
364 STARTING AND OPERATING

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.
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.
A feature of the TCS system, Brake Limited 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 “Sport Mode (Partial Off)”
or#Track Mode (Full Off)#mode. Refer to “Electronic
Stability Control (ESC)” in this section for more informa-
tion.
366 STARTING AND OPERATING

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.
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

STARTING AND OPERATING 367

ESC Operating Modes
The ESC system has two or 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
conditions. 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 on the switch bank in the
center of the instrument panel. To enter the “Partial Off”
mode, momentarily push the “ESC Off” switch and the
#ESC off indicator light#will illuminate. To turn the ESC
on again, momentarily push the “ESC Off” switch and
the#ESC off indicator light#will turn off.
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.
•Trailer Sway control (TSC) is disabled when the
ESC system is in the “Partial Off” mode.
5
STARTING AND OPERATING 369

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 pushing the “ESC Off”
switch. Once the situation requiring “Partial Off”
mode is overcome, turn the ESC on again by momen-
tarily pushing the “ESC Off” switch. This may be done
while the vehicle is in motion.
•When in “Partial Off” mode, the TCS functionality of
ESC, (except for the limited slip feature described in
the TCS section), has been disabled and the “ESC Off
Indicator Light” will be illuminated. All other stability
features of ESC function normally. When in “Partial
Off” mode, the engine power reduction feature of TCS
is disabled, and the enhanced vehicle stability offered
by the ESC system is reduced.
Full Off — If Equipped
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, push 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 Off Indicator Lamp#will
illuminate, and the “ESC off” message may appear in the
Driver Information Display (DID). Refer to “Driver In-
formation Display (DID)” in “Understanding Your In-
strument Panel” for further information. To turn ESC ON
again, momentarily push the “ESC Off” switch.
370 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.$ESC Off$mode is intended for off-highway
or off-road use only.
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.
•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.
