2020 CHRYSLER 300 transmission

154STARTING AND OPERATING
The transmission is controlled using a rotary
electronic gear selector located on the center
console. The transmission gear range (PRNDL/
S) is displayed both above the gear selector and
in the instrument cluster. To select a gear
range, simply rotate the gear selector. To
access the L or S position, push down on the
gear selector and then rotate it. You must also
press the brake pedal to shift the transmission
out of PARK (or NEUTRAL, when the vehicle is stopped or moving at low speeds). To shift past
multiple gear ranges at once (such as PARK to
DRIVE), simply rotate the gear selector to the
appropriate detent. Select the DRIVE range for
normal driving.
NOTE:
In the event of a mismatch between the gear
selector position and the actual transmission
gear (for example, driver selects PARK while
driving), the position indicator will blink continu
-
ously until the selector is returned to the proper
position, or the requested shift can be
completed.
The electronically-controlled transmission
adapts its shift schedule based on driver inputs,
along with environmental and road conditions.
The transmission electronics are
self-calibrating; therefore, the first few shifts on
a new vehicle may be somewhat abrupt. This is
a normal condition, and precision shifts will
develop within a few hundred miles
(kilometers).
Only shift from DRIVE to PARK or REVERSE
when the accelerator pedal is released and the
vehicle is stopped. Be sure to keep your foot on
the brake pedal when shifting between these
gears. Standard Gear Selector
The standard transmission gear selector has
PARK, REVERSE, NEUTRAL, DRIVE, and LOW
shift positions. Using the LOW position manually
downshifts the transmission to a lower gear
based on vehicle speed.

Gear Selector

Premium Gear Selector With AutoStick
The premium transmission gear selector
provides PARK, REVERSE, NEUTRAL, DRIVE,
and SPORT shift positions. Manual shifts can be
made using the AutoStick shift control (shift
paddles mounted on the steering wheel).
Pressing the shift paddles (-/+) while in the
DRIVE or SPORT position will manually select
the transmission gear, and will display the

Allowing children to be in a vehicle unat -
tended 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 transmission gear
selector.
Do not leave the key fob in or near the
vehicle (or in a location accessible to chil -
dren), and do not leave the ignition in the

current gear in the instrument cluster as 1, 2, 3,
etc. Refer to “AutoStick” in this section for
further information.
Gear Ranges
Do not depress the accelerator pedal when
shifting from PARK or NEUTRAL into another
gear range.
NOTE:
After selecting any gear range, wait a moment
to allow the selected gear to engage before
accelerating. This is especially important when
the engine is cold.
PARK (P)
This range supplements the parking brake by
locking the transmission. The engine can be
started in this range. Never attempt to use
PARK while the vehicle is in motion. Apply the
parking brake when exiting the vehicle in this
range.
When parking on a level surface, you may shift
the transmission into PARK first, and then apply
the parking brake. When parking on a hill, apply the parking brake
before shifting the transmission to PARK. As an
added precaution, turn the front wheels toward
the curb on a downhill grade and away from the
curb on an uphill grade.
When exiting the vehicle, always:
Apply the parking brake.
Shift the transmission into PARK.
Turn the ignition OFF.
Remove the key fob from the vehicle.
WARNING!
Never use the PARK position as a substi
-
tute for the parking brake. Always apply the
parking brake fully when exiting the vehicle
to guard against vehicle movement and
possible injury or damage.
Your vehicle could move and injure you and
others if it is not in PARK. Check by trying to
move the transmission gear selector out of
PARK with the brake pedal released. Make
sure the transmission is in PARK before
exiting the vehicle.
The transmission may not engage PARK if
the vehicle is moving. Always bring the
vehicle to a complete stop before shifting to
PARK, and verify that the transmission gear
position indicator solidly indicates PARK (P)
without blinking. Ensure that the vehicle is
completely stopped, and the PARK position
is properly indicated, before exiting the
vehicle.
It is dangerous to shift out of PARK or
NEUTRAL if the engine speed is higher than
idle speed. If your foot is not firmly pressing
the brake pedal, the vehicle could accel -
erate quickly forward or in reverse. You
could lose control of the vehicle and hit
someone or something. Only shift into gear
when the engine is idling normally and your
foot is firmly pressing the brake pedal.

156STARTING AND OPERATING
(Continued)
The following indicators should be used to
ensure that you have properly engaged the
transmission into the PARK position:
Look at the transmission gear position
display and verify that it indicates the PARK
position (P), and is not blinking.
With the brake pedal released, verify that the
gear selector will not move out of PARK.
REVERSE (R)
This range is for moving the vehicle backward.
Shift into REVERSE only after the vehicle has
come to a complete stop.
NEUTRAL (N)
Use this range when the vehicle is standing for
prolonged periods with the engine running.
Apply the parking brake and shift the
transmission into PARK if you must exit the
vehicle.
Unintended movement of a vehicle could
injure those in or near the vehicle. As with
all vehicles, you should never exit a vehicle
while the engine is running. Before exiting a
vehicle, always come to a complete stop,
then apply the parking brake, shift the
transmission into PARK, and turn the igni -
tion OFF. When the ignition is in the OFF
mode, the transmission is locked in PARK,
securing the vehicle against unwanted
movement.
When exiting the vehicle, always make sure
the ignition is in the OFF mode, remove the
key fob from the vehicle, and lock the
vehicle.
Never leave children alone in a vehicle, or
with access to an unlocked vehicle.
Allowing children to be in a vehicle unat -
tended 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 transmission gear
selector.
WARNING! (Continued)
Do not leave the key fob in or near the
vehicle (or in a location accessible to chil -
dren), and do not leave the ignition in the
ACC or ON/RUN mode. A child could
operate power windows, other controls, or
move the vehicle.
CAUTION!
Before moving the transmission gear
selector out of PARK, you must start the
engine, and also press the brake pedal.
Otherwise, damage to the gear selector
could result.
DO NOT race the engine when shifting from
PARK or NEUTRAL into another gear range,
as this can damage the drivetrain.
WARNING! (Continued)
WARNING!
Do not coast in NEUTRAL and never turn off
the ignition to coast down a hill. These are
unsafe practices that limit your response to
changing traffic or road conditions. You might
lose control of the vehicle and have a
collision.

STARTING AND OPERATING157
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 below), transmission operation may
be modified depending on engine and
transmission temperature as well as vehicle
speed. Normal operation will resume once the
transmission temperature has risen to a
suitable level.
SPORT (S) — If Equipped
This mode alters the transmission's automatic
shift schedule 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 clockwise.
Transmission Limp Home Mode
Transmission function is monitored
electronically for abnormal conditions. If a
condition is detected that could result in
transmission damage, Transmission Limp
Home 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 location (preferably, at an
authorized dealer).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 Operating” and “Towing A Disabled
Vehicle” in “In Case Of Emergency” for further
information.

158STARTING AND OPERATING

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
recommend that you visit an authorized dealer
at your earliest possible convenience. An autho -
rized 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 providing manual shift control, giving
you more control of the vehicle. AutoStick allows you to maximize engine braking,
eliminate undesirable upshifts and downshifts,
and improve 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 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 temporary 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 activate
"permanent" AutoStick mode. The transmission
will remain in AutoStick mode until the driver
deliberately disables AutoStick (as described
below). 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.

Paddle Shifters

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 downshift
is chosen, except as described below.
If AutoStick is engaged while in DRIVE mode,
the transmission will automatically shift up
when maximum engine speed is reached. If
the accelerator is fully depressed, the trans -
mission will downshift when possible (based
1 — Shift Paddle Downshift
2 — Shift Paddle Upshift

20_LX_OM_EN_USC_t.book Page 158

STARTING AND OPERATING159
on current vehicle speed and gear). Lack of
accelerator pedal activity will cause the
transmission to revert to automatic opera -
tion.
If AutoStick is engaged while the transmis -
sion 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 acceler -
ator pedal is pressed to the floor.
In either DRIVE or SPORT mode, the transmis -
sion will automatically downshift as the
vehicle slows (to prevent engine lugging) and
will display the current gear.
The transmission will automatically down -
shift 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 down -
shift 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 "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.
SPORT MODE — IF EQUIPPED

SPORT Mode Button

If your vehicle is equipped with SPORT mode,
this mode is a configuration set up for typical
enthusiast driving. The engine, transmission
and steering systems are 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 deactivated by pushing
the SPORT button on the instrument panel
switch bank.
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.
