2016 DODGE CHALLENGER SRT ECU

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 beforedriving. 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
Trailer towing with this vehicle is not recommended.
474 STARTING AND OPERATING

WARNING!
Fast spinning tires can be dangerous. Forces gener-
ated by excessive wheel speeds may cause damage, or
even failure, of the axle and tires. A tire could
explode and injure someone. Do not spin your vehi-
cle’s wheels faster than 30 mph (48 km/h) or for
longer than 30 seconds continuously without stop-
ping when you are stuck and do not let anyone near
a spinning wheel, no matter what the speed.
MANUAL PARK RELEASE — 8 SPEED

WARNING!
Always secure your vehicle by fully applying the
parking brake, before activating the Manual Park
(Continued)
WARNING!(Continued)
Release. Activating the Manual Park Release will
allow your vehicle to roll away if it is not secured by
the parking brake or by proper connection to a tow
vehicle. Activating the Manual Park Release on an
unsecured vehicle could lead to serious injury or
death for those in or around the vehicle.
In order to move the vehicle in cases where the transmis-
sion will not shift out of PARK (such as a dead battery),
a Manual Park Release is available.
Follow these steps to use the Manual Park Release:
1. Firmly apply the parking brake.
2. Remove the console storage bin to access the Manual Park Release lever.

3. Using a small screwdriver or similar tool, fish thetether strap up through the opening in the console
base.
4. Insert the screwdriver into the slot in the center of the lever, and disengage the lever locking tab by pushing
it to the right. 5. While holding the locking tab in the disengaged
position, pull the tether strap to rotate the lever up and
rearward until it locks in place in the vertical position.
The vehicle is now out of PARK and can be moved.
Release the parking brake only when the vehicle is
securely connected to a tow vehicle.

To Reset The Manual Park Release:
1. Push the latch (at the base of the lever, on the rear side)rearward (away from the lever) to unlatch the lever.
2. Rotate the Manual Park Release lever forward and down, to its original position, until the locking tab
snaps into place to secure the lever.
3. Pull up gently on the tether strap to confirm that the lever is locked in its stowed position.
4. Tuck the tether strap into the base of the console. Reinstall the console storage bin.

500 WHAT TO DO IN EMERGENCIES

If you must use the accessories (wipers, defrosters, etc.)
while being towed, the ignition must be in the ON/RUN
position, not the ACC position.
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.
Damage to your vehicle may occur from improper
towing.
• The manufacturer does not recommend towing this
vehicle using a tow dolly. Vehicle damage may
occur.
Automatic Transmission
The manufacturer recommends towing your vehicle with
all four wheels OFF the ground using a flatbed. If flatbed equipment is not available, and the transmis-
sion is operable, the vehicle may be flat towed (with all
four wheels on the ground) under the following condi-
tions:
•
The transmission must be in NEUTRAL. Refer to
Manual Park Release in this section for instructions
on shifting the transmission to NEUTRAL when the
engine is off.
• The towing distance must not exceed 30 miles (48 km).
• The towing speed must not exceed 30 mph (48 km/h).
If the transmission is not operable, or the vehicle must
be towed faster than 30 mph (48 km/h) or farther than 30
miles (48 km), then the only acceptable method of
towing is with a flatbed truck.

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
transmission control systems. When these systems are
operating properly, your vehicle will provide excellent
performance and fuel economy, as well as engine emis-
sions 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. Al-
though 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 emission 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
510 MAINTAINING YOUR VEHICLE

access 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 per-
sonal information. For further information, refer to “Privacy Practices — If
Equipped With Uconnect 8.4 Radio” and “Uconnect
CyberSecurity” in “All About Uconnect Access” in your
Owner ’s Manual Radio Supplement and “Cybersecurity”
in “Understanding Your Instrument Panel” in your Own-
er ’s Manual on the DVD.
Loose Fuel Filler Cap
If the vehicle diagnostic system determines that the fuel
filler cap is loose, improperly installed, or damaged, a
”gASCAP” message will display in the odometer or a
“Check Gascap” message will display in the Driver
Information Display (DID). If this occurs, tighten the fuel
filler cap properly and press the Trip Odometer button to
turn off the message. If the problem continues, the
message will appear the next time the vehicle is started.
A loose, improperly installed, or damaged fuel filler cap
may also turn on the MIL.
