2010 CHRYSLER 300 automatic transmission

Operation
When the shift lever is in the DRIVE position, the
transmission will operate automatically, shifting between
the five available gears. To engage AutoStick, simply
move the shift lever to the right or left (D+/D-) while in
the DRIVE position. The gear position will display in the
instrument cluster. In the AutoStickmode, the transmis-
sion will shift up and down when left or right (D-/D+) is
manually selected by the driver. It will remain in the
selected gear until another upshift or downshift is cho-
sen. The transmission will automatically downshift as the
vehicle slows to a stop (to prevent engine lugging) and
will display the current gear. Tapping the shift lever to
the D+ position (at a stop) will allow starting in second
gear. After a stop, the driver should manually upshift
(D+) the transmission as the vehicle is accelerated. To disengage AutoStick
mode, hold the shift lever to the
right (D+) for a few seconds. You can shift in or out of the
AutoStick mode at any time without taking your foot off
the accelerator 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 an accident
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.
5
STARTING AND OPERATING 329

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 moving the shift lever into the AutoStickmode
(+/-) or activating the windshield wipers for an extended
period of time. Drive mode, RWD or AWD, is displayed
momentarily in the Electronic Vehicle Information Center
(EVIC) in the gage area of the vehicle display when the
transmission is first shifted into gear, and if the drive
mode changes during vehicle operation.
NOTE: If the “t CASE” or “SERVICE AWD SYSTEM”
warning message 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 “Electronic
Vehicle Information Center (EVIC)” in “Understanding
Your Instrument Panel” for further information.
CAUTION!
All wheels must have the same size and type tires.
Unequal tire sizes must not be used. Unequal tire
size may cause failure of the front differential and/or
the transfer case.
DRIVING ON SLIPPERY SURFACES
Acceleration
Rapid acceleration on snow covered, wet, or other slip-
pery surfaces may cause the rear wheels to pull errati-
cally to the right or left. This phenomenon occurs when
there is a difference in the surface traction under the rear
(driving) wheels.

Trailer Towing Weights (Maximum Trailer Weight Ratings)
The following chart provides the maximum trailer weight ratings towable for your given drivetrain.
Engine/TransmissionFrontal AreaMax. GTW
(Gross Trailer Wt.) Max. Tongue Wt.
(See Note)
2.7L & 3.5L Rear Wheel
Drive (RWD) Automatic 22 sq ft (2.04 sq m) 1,000 lbs (454 kg)
100 lbs (45 kg)
3.5L All Wheel Drive
(AWD) & 5.7L Automatic 32 sq ft (2.97 sq m) 2,000 lbs (907 kg)
200 lbs (91 kg)
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. Re-
fer to “Tire Safety Information” in “Starting and Operating” for further information.
Trailer and Tongue Weight
Always load a trailer with 60% to 65% of the weight in
the front of the trailer. This places 10% to 15% of the
Gross Trailer Weight (GTW) on the tow hitch of your
vehicle. Loads balanced over the wheels or heavier in the
rear can cause the trailer to sway severelyside to side which will cause loss of control of the vehicle and trailer.
Failure to load trailers heavier in front is the cause of
many trailer accidents.
Never exceed the maximum tongue weight stamped on
your bumper or trailer hitch.
388 STARTING AND OPERATING

WARNING! (Continued)
•Vehicles with trailers should not be parked on a
grade. When parking, apply the parking brake on
the tow vehicle. Put the tow vehicle automatic
transmission in PARK. Always, block or\bchock\b
the trailer wheels.
•GCWR must not be exceeded.
•Total weight must be distributed between the tow
vehicle and the trailer such that the following four
ratings are not exceeded:
1. Max loading as defined on the “Tire and Load-
ing Information” placard.
2. GTW
3. GAWR
(Continued)
WARNING! (Continued)
4. Tongue weight rating for the trailer hitch utilized.
(This requirement may limit the ability to always
achieve the 10% to 15% range of tongue weight as a
percentage of total trailer weight.)
Towing Requirements – Tires

Do not attempt to tow a trailer while using a compact
spare tire.
Proper tire inflation pressures are essential to the safe
and satisfactory operation of your vehicle. Refer to
“Tires – General Information” in “Starting and Oper-
ating” for information on tire pressures and for proper
tire inflation procedures.
Check the trailer tires for proper tire inflation pres-
sures before trailer usage.

Towing Tips
Before setting out on a trip, practice turning, stopping,
and backing up the trailer in an area located away from
heavy traffic.
Automatic Transmission
The DRIVE range can be selected when towing. How-
ever, if frequent shifting occurs while in this range, select
a lower gear range using the “3” position (if equipped) or
the AutoStick/ERS feature (if equipped).
NOTE:Selecting a lower gear range while operating the
vehicle under heavy operating conditions will improve
performance and extend transmission life by reducing
excessive shifting and heat build up. This action will also
provide better engine braking. If you REGULARLY tow a trailer for more than 45 min-
utes of continuous operation, then change the automatic
transmission fluid and filter according to the interval
specified for “police, taxi, fleet, or frequent trailer tow-
ing.” Refer to “Maintenance Schedule” for the proper
maintenance intervals.
Electronic Speed Control – If Equipped

Do not use in hilly terrain or with heavy loads.
When using the speed control, if you experience speed
drops greater than 10 mph (16 km/h), disengage until
you can get back to cruising speed.
Use speed control in flat terrain and with light loads to
maximize fuel efficiency.

STARTING AND OPERATING 395

WARNING! (Continued)
•Always park on a firm, level surface as far from
the edge of the roadway as possible before raising
the vehicle.
•Block the wheel diagonally opposite the wheel to
be raised.
•Set the parking brake firmly and set an automatic
transmission in PARK; a manual transmission in
REVERSE.
•Never start or run the engine with the vehicle on a
jack.
•Do not let anyone sit in the vehicle when it is on a
jack.
•Do not get under the vehicle when it is on a jack.
•Only use the jack in the positions indicated and
for lifting this vehicle during a tire change.(Continued)
WARNING! (Continued)
•If working on or near a roadway, be extremely
careful of motor traffic.
•To assure that spare tires, flat or inflated, are
securely stowed, spares must be stowed with the
valve stem facing the ground.
•Turn on the Hazard Warning flasher.
1. Remove the spare tire, jack, and lug wrench.

WARNING!
•Take care to avoid the radiator cooling fan when-
ever the hood is raised. It can start anytime the
ignition switch is on. You can be injured by
moving fan blades.
•Remove any metal jewelry such as watch bands or
bracelets that might make an inadvertent electrical
contact. You could be seriously injured.
•Batteries contain sulfuric acid that can burn your
skin or eyes and generate hydrogen gas which is
flammable and explosive. Keep open flames or
sparks away from the battery.
1. Set the parking brake, shift the automatic transmission
into PARK and turn the ignition to LOCK.
