2010 CHRYSLER 300 automatic transmission

CAUTION! (Continued)
•Do not shift from REVERSE, PARK, or NEUTRAL
into any forward gear when the engine is above
idle speed.
•Before shifting into any gear, make sure your foot
is firmly on the brake pedal.
WARNING!
It is dangerous to move the shift lever out of PARK or
NEUTRAL if the engine speed is higher than idle
speed. If your foot is not firmly on the brake pedal,
the vehicle could accelerate 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 when your right foot is
firmly on the brake pedal.
General Information
The automatic transmission selects individual gears au-
tomatically, dependent upon:
•Altitude
•Vehicle loading
•Driving style
•Shift lever position
•Accelerator position
•Vehicle speed
The gear shifting process is continuously adapted, de-
pendent on the driving style, the driving situation, and
the road characteristics.

STARTING AND OPERATING 315

NOTE:
•After selecting any driving position, wait a moment to
allow the gear to engage fully before accelerating,
especially when the engine is cold.
•If there is a need to restart the engine, be sure to turn
the ignition switch to the LOCK position (OFF position
with Keyless Go™) before restarting. Transmission
engagement may be delayed up to 10 seconds after
restart if the ignition switch is not turned to the LOCK
position (OFF position with Keyless Go™) first.
•The electronically-controlled transmission provides a
precise shift schedule. The transmission electronics are
self-calibrating. Therefore, the first few shifts on a new
vehicle may be somewhat abrupt or soft until after the
break-in period. This is a normal condition, and pre-
cision shifts will develop within a few shift cycles.The shift lever is automatically locked while in the PARK
position. To move the shift lever out of the PARK
position, the brake pedal must be firmly pressed before
the shift lock will release.
Move the shift lever to the desired position only when the
engine is idling normally and the brake pedal is applied.
Do not release the brake pedal until ready to drive. The
vehicle may otherwise accelerate quickly when the shift
lever is in the DRIVE or REVERSE position.
316 STARTING AND OPERATING

With Keyless Go™ – If Equipped
If the engine is running, press the START/STOP button to
turn it off. Release the brake pedal and press the START/
STOP button once or twice to go to the ACC or RUN
position. Do not start the engine. Then, follow the in-
structions shown above to activate the override.
Four-Speed Automatic Transmission – If
Equipped
NOTE:Under extreme cold temperatures (-6°F (-21°C)
and when in DRIVE, transmission operation may be
briefly limited to only second gear operation. Normal
operation will resume once the transmission temperature
has risen to a suitable level.
Shifting from DRIVE to PARK or REVERSE should be
done only after the accelerator pedal is released and the
vehicle is stopped. Be sure to keep your foot on the brake
pedal when moving the shift lever between these gears.
Gear Ranges
PARK
This range supplements the parking brake by locking the
transmission. The engine can be started in this range.
Never use PARK while the vehicle is in motion. Apply
the parking brake when leaving the vehicle in this range.

STARTING AND OPERATING 319

•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.
322 STARTING AND OPERATING

NOTE:
•The torque converter clutch will not engage until the
transmission fluid and engine coolant is warm (usu-
ally after 1–3 miles [1.6–4.8 km] of driving). Because
engine speed is higher when the torque converter
clutch is not engaged, it may seem as if the transmis-
sion is not shifting into Overdrive when cold. This is
considered a normal condition. Pulling the shift lever
into the “3” position will show that the transmission is
able to shift into and out of Overdrive.
•If the vehicle has not been driven for several days, the
first few seconds of operation after shifting the trans-
mission into gear may seem sluggish. This is due to the
transmission fluid partially draining from the torque
converter into the transmission. This is considered a
normal condition and it will not cause damage to the
transmission. The torque converter will refill within
five seconds of shifting from PARK into any other gear
position.
Transmission Limp Home Mode
The transmission is monitored for abnormal conditions.
If a condition is detected that could cause damage, the
transmission automatically shifts into second gear. The
transmission remains in second gear despite the forward
gear selected. PARK, REVERSE, and NEUTRAL will
continue to operate. This reset feature allows the vehicle
to be driven to an authorized dealer for service without
damaging the transmission.
If the problem has been momentary, the transmission can
be reset to regain all forward gears.
•Stop the vehicle and shift into PARK.
•Turn the ignition switch to the LOCK position (OFF
position with Keyless Go™), then start the engine.
•Shift into DRIVE and resume driving.

STARTING AND OPERATING 323

NOTE:Even if the transmission can be reset, we recom-
mend that you visit an authorized dealer at your earliest
possible convenience. Your authorized dealer has diag-
nostic equipment to determine if the problem could
recur.
If the transmission cannot be reset, authorized dealer
service is required.
Five-Speed Automatic Transmission – If
Equipped
Shifting from DRIVE to PARK or REVERSE should be
done only after the accelerator pedal is released and the
vehicle is stopped. Be sure to keep your foot on the brake
pedal when moving the shift lever between these gears.
Gear Ranges
PARK
This range supplements the parking brake by locking the
transmission. The engine can be started in this range.
Never use PARK while the vehicle is in motion. Apply
the parking brake when leaving the vehicle in this range.
Shift Lever
324 STARTING AND OPERATING

NEUTRAL
This range is used when the vehicle is standing for
prolonged periods with the engine running. The engine
may be started in this range. Set the parking brake if you
must leave the vehicle.
CAUTION!
Coasting the vehicle or driving for any other reason
with shift lever in NEUTRAL can result in transmis-
sion damage.
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 an accident.
DRIVE
This range should be used for most city and highway
driving. It provides the smoothest upshifts and down-
shifts and the best fuel economy.
The transmission automatically upshifts through fifth
gear. 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 condi-
tions, in hilly terrain, traveling into strong head winds, or
while towing heavy trailers), use the AutoStick/
Electronic Range Select (ERS) mode to select a lower gear.
Delayed Shifts in Cold Temperatures
During cold temperature operation, you may notice
delayed upshifts depending on engine and transmission
temperature as well as vehicle speed. This feature im-
proves warm up time of the engine and transmission to
achieve maximum efficiency.
326 STARTING AND OPERATING

AutoStick/Electronic Range Select (ERS)
Your vehicle may be equipped with AutoStickor Elec-
tronic Range Select (ERS) to provide greater driver con-
trol of automatic transmission operation. Refer to
“AutoStick” in this section.
Electronic Range Select (ERS) – If Equipped
Electronic Range Select (ERS) allows the driver to limit
the highest available transmission gear, providing you
with more control of the vehicle. ERS allows you to
maximize engine braking, eliminate undesirable upshifts,
and improve overall vehicle performance. This system
can also provide you with more control during mountain
driving, trailer towing, and other situations.
ERS Operation
When the shift lever is in the Drive position, the trans-
mission will operate automatically, shifting between the
five available gears. Moving the shift lever to the left (D-)
will activate ERS, downshift the transmission, and dis-
play the top available gear in the instrument cluster. Once in ERS mode, tapping the shift lever to the left (D-) or
right (D+) will change the top available gear. The trans-
mission will not shift above the indicated gear, but will
shift up and down normally (automatically) through the
lower gears. Holding the shift lever to the left (D-) will
shift the transmission to the lowest gear possible (with-
out overspeeding the engine) for maximum engine brak-
ing. Holding the shift lever to the right (D+) for a few
seconds will disengage ERS mode.
AUTOSTICK
— IF EQUIPPED
AutoStickis a driver-interactive transmission feature
that offers manual gear shifting to provide you with 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 situa-
tions.
