2005 CHRYSLER 300 ECU

NOTE:
²
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 ªOverdriveº when cold. This is
considered a normal condition. Pulling the shift lever
into the ª3º position will show that the transmission is
able to shift into and out of ªOverdrive.º
²If 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 will not cause damage to the
transmission. The torque converter will refill within 5
seconds of shifting from P (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 (P), Reverse (R), and Neutral (N) will
continue to operate. This Reset feature allows the vehicle
to be driven to a dealer for service without damaging the
transmission.
If the problem has been momentary, the transmission can
be reset to regain all forward gears.
²Stop the vehicle and shift into PARK (P).
²Turn the key to LOCK then start the engine.
²Shift into ªDº and resume driving.
NOTE:Even if the transmission can be reset, we
recommend that you visit a dealer at your earliest
possible convenience. Your dealer has diagnostic equip-
ment to determine if the problem could recur.
If the transmission cannot be reset, dealer service is
required.

5 Speed Automatic TransmissionWARNING!
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 shift
the transmission into Park, remove the key from the
ignition, and apply the park brake. Once the key is
removed from the ignition the transmission shift
lever is locked in the Park position, securing the
vehicle against unwanted movement. Furthermore,
you should never leave children unattended inside a
vehicle. The following indicators should be used to
ensure that you have engaged the transmission shift
lever into the ªParkº position:
²When shifting into Park move the lever all the
way forward until it stops, and is fully seated.
²Look at the shift indicator window on the console
to ensure it is in the ªPº position.

Park Position
The PARK position is to be used when parking the
vehicle. Engage only with the vehicle stopped. The PARK
position is not intended to serve as a brake when the
vehicle is parked. Rather, the driver should always use
the parking brake in addition to placing the selector lever
in PARK to secure the vehicle.
PARK 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.
NOTE:
²
If the key is in the ACC or ON position, you must press
the brake pedal to shift out of the PARK position.
²The key can be removed from the ignition switch only
with the selector lever in the PARK position. With the
key removed, the selector lever is locked in the PARK
position.
For electrical system malfunctions there is an override for
the interlock system. In order to override this system the
key must be in the ignition with the switch in the ACC orON positions. Remove the rubber storage tray from the
bin located to the right of the shifter lever. The override
can be activated by pressing the pink-colored tab, which
can be accessed through a hole inside the bin. While the
override is pressed, the shifter can be moved out of the
park position without pressing the brake. After operation
return rubber storage tray to its original position.
Reverse
Shift into REVERSE gear only when the vehicle is com-
pletely stopped.

A reset feature is available to allow the vehicle to be
driven to a dealer for service. To reset the transmission,
use the following procedure:
1. Stop the vehicle.
2. Move the selector lever to the PARK position.
3. Turn off the engine.
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.
NOTE:Even if the transmission can be reset, we
recommend that you visit a dealer at your earliest
possible convenience. Your dealer has diagnostic equip-
ment to determine if the problem could recur.Have the transmission checked at your authorized dealer
as soon as possible.
If the problem has been momentary, the transmission can
be reset to regain all forward gears.
Permanent Transmission Limp Home Mode
Permanent Limp Home Mode will be activated if the
transmission enters temporary Limp Home Mode three
times. Follow the reset procedure described in the previ-
ous section. In Permanent Limp Home Mode, PARK(P),
REVERSE(R) and NEUTRAL(N) will continue to operate.
SECOND gear will operate in the DRIVE(D) shifter
position. The malfunction indicator lamp may illuminate.
218 STARTING AND OPERATING

CAUTION!
Damage to the fuel system or emission control
system could result from using an improper fuel
tank filler tube cap (gas cap), and may result in a
malfunction indicator light on the instrument clus-
ter. A poorly fitting cap could let impurities into the
fuel system.
CAUTION!
To avoid fuel spillage and overfilling, do not ªtop
offº the fuel tank after filling. When the fuel nozzle
ªclicksº or shuts off, the fuel tank is full.
NOTE:
²
Tighten the gas cap until you hear a ªclickingº sound.
This is an indication that the gas cap is properly
tightened. If the gas cap is not secured properly the
Malfunction Indicator Light in the instrument cluster
will turn on. Make sure that the gas cap is tightened
each time the vehicle is refueled.
²When the fuel nozzle ªclicksº or shuts off, the fuel
tank is full.

The bar code allows a computer scanner to read the
Vehicle Identification Number (VIN).
Gross Vehicle Weight Rating (GVWR)
The GVWR is the total allowable weight of your vehicle.
This includes driver, passengers, and cargo. The total
load must be limited so that you do not exceed the
GVWR.
Gross Axle Weight Rating (GAWR)
The GAWR is the maximum capacity of the front and rear
axles. Distribute the load over the front and rear axles
evenly. Make sure that you do not exceed either front or
rear GAWR.
WARNING!
Because the front wheels steer the vehicle, it is
important that you do not exceed the maximum front
or rear GAWR. A dangerous driving condition can
result if either rating is exceeded. You could lose
control of the vehicle and have an accident.
Overloading
The load carrying components (axle, springs, tires,
wheels, etc.) of your vehicle will provide satisfactory
service as long as you do not exceed the GVWR and front
and rear GAWR.
The best way to figure out the total weight of your
vehicle is to weigh it when it is fully loaded and ready for
operation. Weigh it on a commercial scale to insure that it
is not over the GVWR.
Figure out the weight on the front and rear of the vehicle
separately. It is important that you distribute the load
evenly over the front and rear axles.
Overloading can cause potential safety hazards and
shorten useful service life. Heavier axles or suspension
components do not necessarily increase the vehicle's
GVWR.
Loading
To load your vehicle properly, first figure out its empty
weight, axle by axle and side by side. Store heavier items
down low and be sure you distribute their weight as
evenly as possible. Stow all loose items securely before
