2009 DODGE CHALLENGER ECU

WARNING!
Driving a vehicle with the red brake light on is
dangerous. Part of the brake system may have failed.
It will take longer to stop the vehicle. You could have
an accident. Have the vehicle checked immediately.
Vehicles equipped with the Anti-Lock Brake System
(ABS), are also equipped with Electronic Brake Force
Distribution (EBD). In the event of an EBD failure, the
Brake Warning Light will turn on along with the ABS
Light. Immediate repair to the ABS system is required.
Operation of the Brake Warning Light can be checked by
turning the ignition switch from the OFF position to the
ON position. The light should illuminate for approxi-
mately two seconds. The light should then turn off unless
the parking brake is applied or a brake fault is detected.
If the light does not illuminate, have the light inspected
by an authorized dealer.The light also will turn on when the parking brake is
applied with the ignition switch in the ON position.
NOTE:This light shows only that the parking brake is
applied. It does not show the degree of brake application.
21. Vehicle Security Light — If Equipped
This light will flash at a fast rate for approxi-
mately 15 seconds, when the vehicle security
alarm is arming, and then will flash slowly
until the vehicle is disarmed.
22. Tire Pressure Monitoring Telltale Light
Each tire, including the spare (if provided),
should be checked monthly, when cold and
inflated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle plac-
ard or tire inflation pressure label. (If your vehicle has tires
of a different size than the size indicated on the vehicle
placard or tire inflation pressure label, you should deter-
mine the proper tire inflation pressure for those tires.)

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
from the ignition, and apply the parking brake. Once
the key is removed from the ignition, the transmis-
sion 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 DRIVE position. After the
transmission cools down, it will return to normal
operation.
Brake/Transmission Shift Interlock System
This vehicle is equipped with a Brake Transmission Shift
Interlock (BTSI) system that holds the shift lever in the
PARK position when the ignition switch is in the LOCK
position and the engine is not running. To move the shift
lever out of the PARK position, the ignition switch must
be turned to any other ignition position (ACC, ON/
RUN) position, and the brake pedal must be pressed
whether or not the engine is running.
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

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 (5.7L Engine)
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.

264 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.
A reset feature is available to allow the vehicle to be
driven to an authorized dealer for service. To reset the
transmission, use the following procedure:
1. Stop the vehicle.
2. Move the shift lever into the PARK position.3. Turn OFF the engine.
4. Wait approximately 10 seconds.
5. Restart the engine.
6. Move the shift lever into 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 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.
If the problem has been momentary, the transmission can
be reset to regain all forward gears.

CAUTION!
•Damage to the fuel system or emissions control
system could result from using an improper fuel
tank filler tube cap (gas cap).
•A poorly fitting gas cap could let impurities into
the fuel system.
•A poorly fitting gas cap may cause the Malfunc-
tion Indicator Light (MIL) to turn on.
•To avoid fuel spillage and overfilling, do not “top
off” the fuel tank after filling. 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.
(Continued)
WARNING! (Continued)
•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.
NOTE:
•Tighten the gas cap until you hear a “clicking” sound.
This is an indication that the gas cap is tightened
properly. The MIL in the instrument cluster may turn
on if the gas cap is not secured properly. 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.
322 STARTING AND OPERATING

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
driving. If weighing the loaded vehicle shows that you
have exceeded either GAWR, but the total load is within
the specified GVWR, you must redistribute the weight.
Improper weight distribution can have an adverse effect
on the way your vehicle steers and handles and the way
the brakes operate.
NOTE:Refer to the “Vehicle Certification Label” affixed
to the rear of the driver’s door for your vehicle’s GVWR
and GAWRs.
TRAILER TOWING
Manual Transmission — If Equipped
Trailer towing with this vehicle is not recommended.In this section, you will find safety tips and information
on limits to the type of towing you can reasonably do
with your vehicle. Before towing a trailer, carefully
review this information to tow your load as efficiently
and safely as possible.
To maintain warranty coverage, follow the requirements
and recommendations in this manual concerning ve-
hicles used for trailer towing.
Common Towing Definitions
The following trailer towing related definitions will assist
you in understanding the following information:
Gross Vehicle Weight Rating (GVWR)
The GVWR is the total allowable weight of your vehicle.
This includes driver, passengers, cargo, and tongue
weight. The total load must be limited so that you do not
exceed the GVWR.
5
STARTING AND OPERATING 325

WARNING! (Continued)
Make certain that the load is secured in the trailer
and it will not shift during travel. When trailering
cargo that is not fully secured, dynamic load shifts
can occur that may be difficult for the driver to
control. You could lose control of your vehicle and
have an accident.
•When hauling cargo or towing a trailer, do not over-
load your vehicle or trailer. Overloading can cause a
loss of control, poor performance, or damage to
brakes, axle, engine, transmission, steering, suspen-
sion, chassis structure, or tires.
•Safety chains must always be used between your
vehicle and trailer. Always connect the chains to the
frame or hook retainers of the vehicle hitch. Cross the
chains under the trailer tongue and allow enough
slack for turning corners.
•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 orchockthe 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 Loading
Information” placard.
2. GTW
3. GAWR
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.)
