ECU DODGE CHARGER 2017 7.G Service Manual

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.
• Refer to the “Tire Placard” for your vehicle’s proper tire
pressure.
TRAILER TOWING
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 the New Vehicle Limited Warranty coverage,
follow the requirements and recommendations in this
manual concerning vehicles 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. Refer to “Vehicle Loading/Vehicle Certification
Label” in “Starting And Operating” for further informa-
tion.
Gross Trailer Weight (GTW)
The GTW is the weight of the trailer plus the weight of all
cargo, consumables and equipment (permanent or tempo-
rary) loaded in or on the trailer in its
loaded and ready for
operation condition.
The recommended way to measure GTW is to put your
fully loaded trailer on a vehicle scale. The entire weight of
the trailer must be supported by the scale.

STARTING AND OPERATING 401

Trailer And Tongue Weight
Never exceed the maximum tongue weight stamped on
your bumper or trailer hitch.
Consider the following items when computing the weight
on the rear axle of the vehicle:
•The tongue weight of the trailer.
• The weight of any other type of cargo or equipment put
in or on your vehicle.
• The weight of the driver and all passengers. NOTE:
Remember that everything put into or on the
trailer adds to the load on your vehicle. Also, additional
factory-installed options or dealer-installed options must
be considered as part of the total load on your vehicle.
Refer to the “Tire And Loading Information” placard for
the maximum combined weight of occupants and cargo for
your vehicle.
Towing Requirements
To promote proper break-in of your new vehicle drivetrain
components the following guidelines are recommended:
WARNING!
Improper towing can lead to an injury collision. Follow
these guidelines to make your trailer towing as safe as
possible:
• 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 a collision.

WHAT TO DO IN EMERGENCIES 435

Proper towing or lifting equipment is required to prevent
damage to your vehicle. Use only tow bars and other
equipment designed for this purpose, following equipment
manufacturer ’s instructions. Use of safety chains is man-
datory. Attach a tow bar or other towing device to main
structural members of the vehicle, not to bumpers or
associated brackets. State and local laws regarding vehicles
under tow must be observed.
If you must use the accessories (wipers, defrosters, etc.)
while being towed, the ignition must be in the ON/RUN
mode, not the ACC mode.
If the key fob is unavailable, or the vehicle’s battery is
discharged, refer toManual Park Release in this section
for instructions on shifting the automatic transmission out
of PARK for towing.
CAUTION!
• DO NOT use sling-type equipment when towing.
Vehicle damage may occur.
• When securing the vehicle to a flatbed truck, do not
attach to front or rear suspension components. Dam-
age to your vehicle may result from improper towing.
(Continued)
CAUTION! (Continued)
•The manufacturer does not recommend towing this
vehicle using a tow dolly. Vehicle damage may occur.
All Wheel Drive (AWD) Models
The manufacturer recommends towing your vehicle with
all four wheels OFF the ground using a flatbed.
If the transmission and driveline are operable, AWD mod-
els can also be towed with the ignition in the ON/RUN
mode, the transmission in NEUTRAL (not in PARK!), and
the rear wheels OFF the ground with no limitation on
speed or distance. Since the ignition MUST be in the
ON/RUN mode to tow in this manner, AWD vehicles must
be towed with ALL FOUR wheels OFF the ground (e.g. on
a flatbed truck) if the key fob is unavailable.
CAUTION!
•Towing this vehicle using any other method can cause
severe transmission and/or transfer case damage.
• Damage from improper towing is not covered under
the New Vehicle Limited Warranty.

ONBOARD DIAGNOSTIC SYSTEM — OBD II
Your vehicle is equipped with a sophisticated onboard
diagnostic system called OBD II. This system monitors the
performance of the emissions, engine, and automatic trans-
mission control systems. When these systems are operating
properly, your vehicle will provide excellent performance
and fuel economy, as well as engine emissions well within
current government regulations.
If any of these systems require service, the OBD II system
will turn on the “Malfunction Indicator Light (MIL)”. It
will also store diagnostic codes and other information to
assist your service technician in making repairs. Although
your vehicle will usually be drivable and not need towing,
see your authorized dealer for service as soon as possible.
CAUTION!
•Prolonged driving with the MIL on could cause
further damage to the emissions control system. It
could also affect fuel economy and driveability. The
vehicle must be serviced before any emissions tests
can be performed.
• If the MIL is flashing while the engine is running,
severe catalytic converter damage and power loss
will soon occur. Immediate service is required.
Onboard Diagnostic System (OBD II) Cybersecurity
Your vehicle is required to have an Onboard Diagnostic
system (OBD II) and a connection port to allow access to
information related to the performance of your emissions
controls. Authorized service technicians may need to ac-
cess this information to assist with the diagnosis and
service of your vehicle and emissions system.
WARNING!
• ONLY an authorized service technician should con-
nect equipment to the OBD II connection port in
order to diagnose or service your vehicle.
• If unauthorized equipment is connected to the OBD
II connection port, such as a driver-behavior tracking
device, it may:
• Be possible that vehicle systems, including safety
related systems, could be impaired or a loss of
vehicle control could occur that may result in an
accident involving serious injury or death.
• Access, or allow others to access, information
stored in your vehicle systems, including personal
information.
