engine CHRYSLER 300 2010 1.G Workshop Manual

WARNING!
Unintended movement of a vehicle could injure
those in and near the vehicle. As with all vehicles,
you should never exit a vehicle while the engine is
running. Before exiting a vehicle, you should always
shift the transmission into PARK, remove the key fob
from the ignition, and apply the parking brake. Once
the key fob is removed from the ignition, the shift
lever is locked in the PARK position, securing the
vehicle against unwanted movement. Furthermore,
you should never leave unattended children inside a
vehicle.
Over-Temperature Mode
The transmission electronics constantly monitor the
transmission oil temperature. If the transmission exceeds
normal operating temperature, the transmission will
change the way it shifts to help control the condition.This may result in a slightly different feeling or response
during normal operation in the DRIVE position. After the
transmission cools down, it will return to normal
operation.
Key Ignition Park Interlock
This vehicle is equipped with a Key Ignition Park Inter-
lock which requires the shift lever to be placed in PARK
prior to rotating the key fob to the LOCK position. The
key fob can only be removed from the ignition when the
ignition is in the LOCK position and once removed the
shift lever is locked in PARK.
Brake/Transmission Shift Interlock System
This vehicle is equipped with a Brake Transmission Shift
Interlock System (BTSI) that holds the shift lever in the
PARK position when the ignition switch is in the LOCK
position (OFF position with Keyless Go™). To move the
shift lever out of the PARK position, the ignition switch
must be turned to the ON or START position (engine
running or not) and the brake pedal must be pressed.

STARTING AND OPERATING 317

Brake/Transmission Interlock Manual Override
There is an override for the BTSI that allows you to move
the shift lever out of the PARK position if an electrical
system malfunction occurs (i.e., dead battery). To access
the override, remove the rubber tray from the storage bin
located to the right of the shift lever. The override access
port is at the top of the bin to the right of the shift lever
gate.
1. Turn the ignition switch to the ACC or ON position
(RUN position with Keyless Go™) without starting the
engine.
2. Firmly set the parking brake.
3. Press and maintain firm pressure on the brake pedal.
4. Using the screwdriver, press and hold the override tab
through the access port on the center console.5. Move the shift lever into the NEUTRAL position.
6. The vehicle may then be started in NEUTRAL.
7. Reinstall the override cover.
Interlock Manual Override
318 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.
Shift Lever
5
STARTING AND OPERATING 319

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.
“D” (Overdrive)
This range is used for most city and highway driving. It
provides the smoothest up shifts and down shifts and the
best fuel economy. Select the “3” range when frequent
transmission shifting occurs when using the Overdrive
range, such as when operating the vehicle under heavy
loading conditions (in hilly terrain, traveling into strong
head winds, or while towing heavy trailers).
NOTE:
•If the vehicle is started in cold temperatures, shifts into
Overdrive may be delayed. Normal Overdrive and
shifting operation will resume when the temperature
of the transmission reaches the appropriate tempera-
ture. Refer to the “Note” under “Torque Converter
Clutch” later in this section.5
STARTING AND OPERATING 321

•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.

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

Temporary Transmission Limp Home Mode
The transmission is monitored for abnormal conditions.
If a condition is detected that could result in transmission
damage, the transmission will engage Limp Home Mode.
If vehicle acceleration worsens, or the transmission no
longer shifts, the transmission is most likely operating in
the Limp Home Mode. In this mode, the transmission
will remain in the current gear until the vehicle is
brought to a stop. After the vehicle has stopped, PARK,
REVERSE, and NEUTRAL will continue to operate. Sec-
ond gear will operate in the DRIVE position. The Mal-
function Indicator Light (MIL) may be illuminated.
If the problem has been momentary, the transmission can
be reset to regain all forward gears. To reset the trans-
mission, use the following procedure:
1. Stop the vehicle.
2. Move the shift lever to the PARK position.3. Turn the engine off.
4. Wait approximately 10 seconds.
5. Restart the engine.
6. Move the shift lever to the desired range. If the
problem is no longer detected, the transmission will
return to normal operation.
If the transmission cannot be reset, see your authorized
dealer.
NOTE:
Even if the transmission can be reset, we recom-
mend that you visit your authorized dealer at your
earliest possible convenience. Your authorized dealer has
diagnostic equipment to determine if the problem could
recur.
Have the transmission checked at your authorized dealer
as soon as possible.

STARTING AND OPERATING 327

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.
