2005 CHRYSLER 300 SRT ECU

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:
•
If the key is in the ACC or ON position, you must press
the brake pedal to shift out of the PARK position.
•The 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.

NOTE:
•
Tighten the gas cap until you hear a “clicking” 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.
•When the fuel nozzle “clicks” or shuts off, the fuel
tank is full.
WARNING!
•Never have any smoking materials lit in or near
the vehicle when the gas cap is removed or the
tank filled.
•Never add fuel to the vehicle when the engine is
running.
•A fire may result if gasoline is pumped into a
portable container that is inside of a vehicle. You
could be burned. Always place gas containers on
the ground while filling.
VEHICLE LOADING
The load carrying capacity of your vehicle is shown in the
charts that follow. This information should be used for
passenger and luggage loading as indicated.
If the seatbacks are folded for carrying cargo, do not
exceed the specified GVWR and GAWR.
Vehicle Certification Label
Your vehicle has a certification label attached to the rear
of the driver’s door.
The label contains the following information:
•Name of manufacturer
•Month and year of manufacture
•Gross Vehicle Weight Rating (GVWR)
•Gross Axle Weight Rating (GAWR) front
•Gross Axle Weight Rating (GAWR) rear
•Vehicle Identification Number (VIN)
•Type of Vehicle
•Month Day and Hour of Manufacture (MDH)
STARTING AND OPERATING 219

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
220 STARTING AND OPERATING

•If frequent coolant additions are required, or if the
level in the coolant recovery bottle does not drop when
the engine cools, the cooling system should be pres-
sure tested for leaks.
•Maintain coolant concentration at 50% HOAT engine
coolant (minimum) and distilled water for proper
corrosion protection of your engine which contains
aluminum components.
•Make sure that the radiator and coolant recovery
bottle overflow hoses are not kinked or obstructed.
•Keep the front of the radiator clean. If your vehicle is
equipped with air conditioning, keep the front of the
condenser clean, also.
•Do not change the thermostat for summer or winter
operation. If replacement is ever necessary, install
ONLY the correct type thermostat. Other designs may
result in unsatisfactory coolant performance, poor gas
mileage, and increased emissions.
Hoses And Vacuum/Vapor Harnesses
Inspect surfaces of hoses and nylon tubing for evidence
of heat and mechanical damage. Hard or soft spots,
brittle rubber, cracking, tears, cuts, abrasions, and exces-
sive swelling indicate deterioration of the rubber.
Pay particular attention to those hoses nearest to high
heat sources such as the exhaust manifold. Inspect hose
routing to be sure hoses do not come in contact with any
heat source or moving component which may cause heat
damage or mechanical wear.
Insure nylon tubing in these areas has not melted or
collapsed.
Inspect all hose connections such as clamps and cou-
plings to make sure they are secure and no leaks are
present.
Components should be replaced immediately if there is
any evidence of wear or damage that could cause failure.
256 MAINTAINING YOUR VEHICLE

Brakes
In order to assure brake system performance, all brake
system components should be inspected periodically.
Suggested service intervals can be found in the Mainte-
nance Schedules section of this manual.
WARNING!
Riding the brakes can lead to brake failure and
possibly an accident. Driving with your foot resting
or riding on the brake pedal can result in abnormally
high brake temperatures, excessive lining wear, and
possible brake damage. You wouldn’t have your full
braking capacity in an emergency.
Brake And Power Steering Hoses
When the vehicle is serviced for scheduled maintenance,
inspect surface of hoses and nylon tubing for evidence of
heat and mechanical damage. Hard and brittle rubber,
cracking, tears, cuts, abrasion, and excessive swelling
indicate deterioration of the rubber. Particular attention
should be made to examining those hose surfaces nearest
to high heat sources, such as the exhaust manifold.Insure nylon tubing in these areas has not melted or
collapsed.
Inspect all hose connections such as clamps and cou-
plings to make sure they are secure and no leaks are
present.
NOTE:Often, fluid such as oil, power steering fluid,
and brake fluid are used during assembly plant opera-
tions to facilitate the assembly of hoses to couplings.
Therefore, oil wetness at the hose-coupling area is not
necessarily an indication of leakage. Actual dripping of
hot fluid when systems are under pressure (during
vehicle operation), should be noted before a hose is
replaced based on leakage.
NOTE:Inspection of brake hoses should be performed
whenever the brake system is serviced and at every
engine oil change. Inspect hydraulic brake hoses for
surface cracking, scuffing, or worn spots. If there is any
evidence of cracking, scuffing, or worn spots, the hose
should be replaced immediately! Eventual deterioration
of the hose can take place resulting in a possibility of a
burst failure.
