engine CHRYSLER 300 2018 Repair Manual

CAUTION!
Towing the vehicle, coasting, or driving for any other
reason with the transmission in NEUTRAL can cause
severe transmission damage.
Refer to “Recreational Towing” in “Starting And Op-
erating” and “Towing A Disabled Vehicle” in “In Case
Of Emergency” for further information.
DRIVE (D)
This range should be used for most city and highway
driving. It provides the smoothest upshifts and downshifts,
and the best fuel economy. The transmission automatically
upshifts through all forward gears. The DRIVE position
provides optimum driving characteristics under all normal
operating conditions.
When frequent transmission shifting occurs (such as when
operating the vehicle under heavy loading conditions, in
hilly terrain, traveling into strong head winds, or while
towing a heavy trailer), use the AutoStick shift control (if
equipped, refer to “AutoStick” in this section for further
information) to select a lower gear. Under these conditions,
using a lower gear will improve performance and extend
transmission life by reducing excessive shifting and heat
buildup. During extremely cold temperatures (-22°F [-30°C] or be-
low), transmission operation may be modified depending
on engine and transmission temperature as well as vehicle
speed. Normal operation will resume once the transmis-
sion temperature has risen to a suitable level.
SPORT (S) — If Equipped
This mode alters the transmission’s automatic shift sched-
ule for sportier driving. Upshift speeds are increased to
make full use of available engine power.
To access SPORT mode, push down on the gear selector
and rotate it fully clockwise, or push the SPORT button in
the center stack.
LOW (L) — If Equipped
Use this range for engine braking when descending very
steep grades. In this range, the transmission will downshift
for increased engine braking. To access the LOW position,
push down on the gear selector and rotate it fully clock-
wise.
Transmission Limp Home Mode
Transmission function is monitored electronically for ab-
normal conditions. If a condition is detected that could
result in transmission damage, Transmission Limp Home
6
STARTING AND OPERATING 231

Mode is activated. In this mode, the transmission may
operate only in certain gears, or may not shift at all. Vehicle
performance may be severely degraded and the engine
may stall. In some situations, the transmission may not
re-engage if the engine is turned off and restarted. The
Malfunction Indicator Light (MIL) may be illuminated. A
message in the instrument cluster will inform the driver of
the more serious conditions, and indicate what actions may
be necessary.
In the event of a momentary problem, the transmission can
be reset to regain all forward gears by performing the
following steps:
NOTE:In cases where the instrument cluster message
indicates the transmission may not re-engage after engine
shutdown, perform this procedure only in a desired loca-
tion (preferably, at an authorized dealer).
1. Stop the vehicle.
2. Shift the transmission into PARK, if possible. If not, shift the transmission to NEUTRAL.
3. Push and hold the ignition switch until the engine turns OFF.
4. Wait approximately 30 seconds. 5. Restart the engine.
6. Shift into the desired gear range. If the problem is no
longer detected, the transmission will return to normal
operation.
NOTE: Even if the transmission can be reset, we recom-
mend that you visit an authorized dealer at your earliest
possible convenience. An authorized dealer has diagnostic
equipment to assess the condition of your transmission.
If the transmission cannot be reset, authorized dealer
service is required.
AutoStick — If Equipped
AutoStick is a driver-interactive transmission feature pro-
viding manual shift control, giving you more control of the
vehicle. AutoStick allows you to maximize engine braking,
eliminate undesirable upshifts and downshifts, and im-
prove overall vehicle performance.
This system can also provide you with more control during
passing, city driving, cold slippery conditions, mountain
driving, trailer towing, and many other situations.
Operation
When the transmission is in DRIVE or SPORT mode, it will
operate automatically, shifting between the eight available
232 STARTING AND OPERATING

gears. To engage AutoStick, simply tap one of the steering
wheel-mounted shift paddles (+/-) while in DRIVE or
SPORT mode. In DRIVE mode, this will activate a tempo-
rary AutoStick mode. The transmission will revert back to
normal operation after a period of time, depending on
accelerator pedal activity. When the transmission gear
selector is in the SPORT position, tapping either shift
paddle will activatepermanentAutoStick mode. The
transmission will remain in AutoStick mode until the
driver deliberately disables AutoStick (as described be-
low). Tapping (-) to enter AutoStick will downshift the
transmission to the next lower gear, while using (+) to enter
AutoStick will retain the current gear. When AutoStick is
active, the current transmission gear is displayed in the
instrument cluster.
In AutoStick mode, the transmission will shift up or down
when (+/-) is manually selected by the driver, unless an
engine lugging or overspeed condition would result. It will
remain in the selected gear until another upshift or down-
shift is chosen, except as described below.
• If AutoStick is engaged while in DRIVE mode, the
transmission will automatically shift up when maxi-
mum engine speed is reached. If the accelerator is fully depressed, the transmission will downshift when pos-
sible (based on current vehicle speed and gear). Lack of
accelerator pedal activity will cause the transmission to
revert to automatic operation.
• If AutoStick is engaged while the transmission gear
selector is in the SPORT position, manual gear selection
will be maintained until the gear selector is returned to
DRIVE, or as described below. The transmission will not
upshift automatically at redline in this mode, nor will
downshifts be obtained if the accelerator pedal is
pressed to the floor.
• In either DRIVE or SPORT mode, the transmission will
automatically downshift as the vehicle slows (to prevent
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.

STARTING AND OPERATING 233

•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 enabled.
• 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 DorS 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 accel-
erator pedal.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.
SPORT MODE — IF EQUIPPED
Your vehicle is equipped with a Sport Mode feature. This
mode is a configuration set up for typical enthusiast
driving. The engine, transmission and steering systems are
Sport Mode Button

all set to their SPORT settings. Sport Mode will provide
improved throttle response and modified shifting for an
enhanced driving experience, as well the greatest amount
of steering feel. This mode may be activated and deacti-
vated by pushing the Sport button on the instrument panel
switch bank.
FUEL SAVER TECHNOLOGY 5.7L 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.
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.
WARNING!
Continued operation with reduced assist could pose a
safety risk to yourself and others. Service should be
obtained as soon as possible.
Alternate electric power steering efforts can be selected
through the Uconnect System. Refer to ”Customer Pro-
grammable Features” within “Uconnect Settings” in “Mul-
timedia” for further information. If the Electric Power Steering warning icon is
displayed and the “SERVICE POWER STEER-
ING” or the “POWER STEERING ASSIST OFF –
SERVICE SYSTEM” message is displayed within
the instrument cluster display, this indicates the vehicle
needs to be taken to the dealer for service. Refer to
“Warning Lights And Messages” in “Getting To Know
Your Instrument Panel” for further information.

STARTING AND OPERATING 235

NOTE:
•When you override and push the SET (+)button or SET
(-) buttons, the new Set Speed will be the current speed
of the vehicle.
• When you use the SET (-)button to decelerate, if the
engine’s braking power does not slow the vehicle suffi-
ciently to reach the set speed, the brake system will
automatically slow the vehicle.
• The ACC system decelerates the vehicle to a full stop
when following a target vehicle. If an ACC host vehicle
follows a target vehicle to a standstill, after two seconds
the driver will either have to push the RES (resume)
button, or apply the accelerator pedal to reengage the
ACC to the existing Set Speed.
• The ACC will bring the vehicle to a complete stop while
following a target vehicle and hold the vehicle for two
seconds in the stop position. If the target vehicle does
not start moving within two seconds, the ACC system
will display a message that the system will release the
brakes and that the brakes must be applied manually. An
audible chime will sound when the brakes are released. •
The ACC system maintains set speed when driving up
hill and down hill. However, a slight speed change on
moderate hills is normal. In addition, downshifting may
occur while climbing uphill or descending downhill.
This is normal operation and necessary to maintain set
speed. When driving up hill and down hill, the ACC
system will cancel if the braking temperature exceeds
normal range (overheated).
Setting The Following Distance In ACC
The specified following distance for ACC can be set by
varying the distance setting between four bars (longest),
three bars (long), two bars (medium) and one bar (short).
Using this distance setting and the vehicle speed, ACC
calculates and sets the distance to the vehicle ahead. This
distance setting displays in the instrument cluster display.
246 STARTING AND OPERATING

WARNING!
•Never have any smoking materials lit in or near the
vehicle when the fuel door is open or the tank is
being filled.
• Never add fuel when the engine is running. This is
in violation of most state and federal fire regulations
and may cause the “Malfunction Indicator Light” to
turn on.
• A fire may result if fuel is pumped into a portable
container that is inside of a vehicle. You could be
burned. Always place fuel containers on the ground
while filling.
CAUTION!
To avoid fuel spillage and overfilling, do not “top off”
the fuel tank after filling.
Emergency Fuel Filler Door Release
If you are unable to open the fuel filler door, use the fuel
filler door emergency release located in the trunk.
Follow the steps below to open the fuel door in case of an
emergency:
1. Open the trunk.
2. Remove the access cover (located on the left side inner trim panel).
Access Cover
280 STARTING AND OPERATING

Trailer Frontal Area
The frontal area is the maximum height multiplied by the
maximum width of the front of a trailer.
Trailer Sway Control
The trailer sway control can be a mechanical 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.
If equipped, the electronic Trailer Sway Control (TSC)
recognizes a swaying trailer and automatically applies
individual wheel brakes and/or reduces engine power to
attempt to eliminate the trailer sway.
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 leverage
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 manufacturer’s directions, it provides
for a more level ride, offering more consistent steering and
brake control thereby enhancing towing safety. The addi-
tion 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.

Refer to local laws for maximum trailer towing speeds.
NOTE: The trailer tongue weight must be considered as
part of the combined weight of occupants and cargo, and it
should never exceed the weight referenced on the “Tire and
Loading Information” placard. Refer to “Tire Safety Infor-
mation” in “Servicing And Maintenance” for further infor-
mation.
Trailer And Tongue Weight
Never exceed the maximum tongue weight stamped on
your bumper or trailer hitch.
Weight Distribution
286 STARTING AND OPERATING

Consider the following items when computing the weight
on the rear axle of the vehicle:
•The tongue weight of the trailer.
• The weight of any other type of cargo or equipment put
in or on your vehicle.
• The weight of the driver and all passengers.
NOTE: Remember that everything put into or on the
trailer adds to the load on your vehicle. Also, additional
factory-installed options or dealer-installed options must
be considered as part of the total load on your vehicle.
Refer to the “Tire And Loading Information” placard for
the maximum combined weight of occupants and cargo for
your vehicle.
Towing Requirements
To promote proper break-in of your new vehicle drivetrain
components, the following guidelines are recommended.
WARNING!
Improper towing can lead to a collision. Follow these
guidelines to make your trailer towing as safe as
possible:
• Make certain that the load is secured in the trailer
and 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 a collision.
• 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, sus-
pension, chassis structure or tires.
• Safety chains must always be used between your
vehicle and trailer. Always connect the chains to the
hook retainers of the vehicle hitch. Cross the chains
under the trailer tongue and allow enough slack for
turning corners.
