2021 DODGE CHARGER engine

STARTING AND OPERATING101
When ACC Is Active:

When you use the SET (-) button to decelerate, if
the engine’s braking power does not slow the
vehicle sufficiently to reach the set speed, the
brake system will automatically slow the vehicle.

The ACC system applies the brake down to a full
stop when following the vehicle in front. If your
vehicle follows the vehicle in front to a standstill,
your vehicle will release the brakes two seconds
after coming to a full stop.

The ACC system maintains set speed when
driving uphill and downhill. However, a slight
speed change on moderate hills is normal.
In addition, downshifting may occur while
climbing uphill or descending downhill. This is
normal operation and necessary to maintain set
speed. When driving uphill and downhill, the ACC
system will cancel if the braking temperature
exceeds normal range (overheated).

Setting The Following Distance In ACC

The specified following distance for ACC can be set
by varying the distance setting between four bars
(longest), three bars (long), two bars (medium) and
one bar (short). Using this distance setting and the
vehicle speed, ACC calculates and sets the distance
to the vehicle ahead. This distance setting appears
in the instrument cluster display. Distance Settings

To increase the distance setting, push the
Distance Setting Increase button and release.
Each time the button is pushed, the distance
setting increases by one bar (longer).
To decrease the distance setting, push the
Distance Setting Decrease button and release.
Each time the button is pushed, the distance
setting decreases by one bar (shorter).
If there is no vehicle ahead, the vehicle will
maintain the set speed. If a slower moving vehicle
is detected in the same lane, the instrument
cluster display will show the ACC Set With Target
Detected Indicator Light, and the system will adjust the vehicle speed automatically to maintain the
distance setting, regardless of the set speed.

The vehicle will then maintain the set distance until:

The vehicle ahead accelerates to a speed above
the set speed.
The vehicle ahead moves out of your lane or
view of the sensor.
The distance setting is changed.
The system disengages Ú
page 99.
The maximum braking applied by ACC is limited;
however, the driver can always apply the brakes
manually, if necessary.
NOTE:The brake lights will illuminate whenever the ACC
system applies the brakes.

A Proximity Warning will alert the driver if ACC
predicts that its maximum braking level is not
sufficient to maintain the set distance. If this occurs,
a visual alert “BRAKE” will flash in the instrument
cluster display and a chime will sound while ACC
continues to apply its maximum braking capacity.

NOTE:The “BRAKE!” screen in the instrument cluster
display is a warning for the driver to take action
and does not necessarily mean that the Forward
Collision Warning system is applying the brakes
autonomously.

114STARTING AND OPERATING
VEHICLE LOADING
The load carrying capacity of your vehicle is shown
on the Vehicle Certification Label. This information
should be used for passenger and luggage loading
as indicated.
Do not exceed the specified Gross Vehicle Weight
Rating (GVWR) or the Gross Axle Weight Rating
(GAWR).
VEHICLE CERTIFICATION LABEL
Your vehicle has a Vehicle Certification Label
affixed to the drivers side B-pillar or 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 (MDH) of manufacture
The bar code allows a computer scanner to read
the 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!
Never have any smoking materials lit in or
near the vehicle when the fuel door is open or
the tank is being filled.
Never add fuel when the engine is running.
This is in violation of most state and federal
fire regulations and may cause the Malfunc -
tion Indicator Light to turn on.
A fire may result if fuel is pumped into a
portable container that is inside of a vehicle.
You could be burned. Always place fuel
containers on the ground while filling.
CAUTION!
To avoid fuel spillage and overfilling, do not “top
off” the fuel tank after filling.
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 a collision.

21_LD_OM_EN_USC_t.book Page 114

116STARTING AND OPERATING
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 Ú page 114.
Tongue Weight (TW)
The TW is the downward force exerted on the hitch
ball by the trailer. You must consider this as part of
the load on your vehicle.
Trailer Frontal Area
The frontal area is the maximum height multiplied
by the maximum width of the front of a trailer.
Trailer Sway Control (TSC)
The TSC can be a mechanical telescoping link that
can be installed between the hitch receiver and the
trailer tongue that typically provides adjustable
friction associated with the telescoping motion to
dampen any unwanted trailer swaying motions
while traveling.
If equipped, the electronic TSC recognizes a
swaying trailer and automatically applies individual
wheel brakes and/or reduces engine power to
attempt to eliminate the trailer sway.
Weight-Carrying Hitch
A weight-carrying hitch supports the trailer tongue
weight, just as if it were luggage located at a hitch
ball or some other connecting point of the vehicle.
These kinds of hitches are commonly used to tow
small and medium sized trailers.
Weight-Distributing Hitch

A weight-distributing system works by applying
leverage through spring (load) bars. They are
typically used for heavier loads to distribute trailer
tongue weight to the tow vehicle's front axle and the
trailer axle(s). When used in accordance with the
manufacturer's directions, it provides for a more
level ride, offering more consistent steering and
brake control thereby enhancing towing safety.
The addition of a friction/hydraulic sway control
also dampens sway caused by traffic and
crosswinds and contributes positively to tow
vehicle and trailer stability. Trailer sway control
and a weight distributing (load equalizing) hitch are
recommended for heavier Tongue Weights (TW) and
may be required depending on vehicle and trailer
configuration/loading to comply with Gross Axle
Weight Rating (GAWR) requirements.

WARNING!
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 a collision.
WARNING!
An improperly adjusted weight-distributing
hitch system may reduce handling, stability,
braking performance, and could result in a
collision.
Weight-distributing systems may not be
compatible with surge brake couplers. Consult
with your hitch and trailer manufacturer or a
reputable Recreational Vehicle dealer for
additional information.

TRAILER AND TONGUE WEIGHT
Never exceed the maximum tongue weight
stamped on your fascia/bumper or trailer hitch.
Weight Distribution
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 equip
-
ment 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 Infor -
mation 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.CAUTION!
Always load a trailer with 60% of the weight in
the front of the trailer. This places 10% of the
GTW on the tow hitch of your vehicle. Loads
balanced over the wheels or heavier in the rear
can cause the trailer to sway severely side to
side which will cause loss of control of the
vehicle and trailer. Failure to load trailers heavier
in front is the cause of many trailer collisions.
WARNING!
Make certain that the load is secured in the
trailer and 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.

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,
suspension, chassis structure or tires.
Safety chains must always be used between your
vehicle and trailer. Always connect the chains to
the 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
transmission in PARK. Always, block or
"chock" the 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 :
Max loading as defined on the “Tire and
Loading Information” placard.
GTW
GAWR
Tongue weight rating for the trailer hitch
utilized.
WARNING!

21_LD_OM_EN_USC_t.book Page 118

STARTING AND OPERATING119
Perform the maintenance listed in the “Scheduled
Servicing” for the proper maintenance intervals
Ú page 245. When towing a trailer, never exceed
the GAWR or GCWR ratings.
Towing Requirements — Tires
Do not attempt to tow a trailer while using a
compact spare tire.
Do not drive more than 50 mph (80 km/h) when
towing while using a full size spare tire.
Proper tire inflation pressures are essential to
the safe and satisfactory operation of your
vehicle.
Check the trailer tires for proper tire inflation
pressures before trailer usage.
Check for signs of tire wear or visible tire
damage before towing a trailer. For the proper
inspection procedure.
Replacing tires with a higher load carrying
capacity will not increase the vehicle's GVWR
and GAWR limits.
For further information Ú page 275.
Towing Requirements — Trailer Brakes
Do not interconnect the hydraulic brake system
or vacuum system of your vehicle with that of
the trailer. This could cause inadequate braking
and possible personal injury.
An electronically actuated trailer brake
controller is required when towing a trailer with
electronically actuated brakes. When towing a
trailer equipped with a hydraulic surge actuated
brake system, an electronic brake controller is
not required.
Trailer brakes are recommended for trailers
over 1,000 lb (453 kg) and required for trailers
in excess of 2,000 lb (907 kg).
CAUTION!
Do not tow a trailer at all during the first
500 miles (805 km) the new vehicle is driven.
The engine, axle or other parts could be
damaged.
Then, during the first 500 miles (805 km) that
a trailer is towed, do not drive over 50 mph
(80 km/h) and do not make starts at full
throttle. This helps the engine and other parts
of the vehicle wear in at the heavier loads.
WARNING!
Do not connect trailer brakes to your vehicle's
hydraulic brake lines. It can overload your
brake system and cause it to fail. You might
not have brakes when you need them and
could have an accident.
Towing any trailer will increase your stopping
distance. When towing, you should allow for
additional space between your vehicle and the
vehicle in front of you. Failure to do so could
result in an accident.
CAUTION!
If the trailer weighs more than 1,000 lb (453 kg)
loaded, it should have its own brakes and they
should be of adequate capacity. Failure to do
this could lead to accelerated brake lining wear,
higher brake pedal effort, and longer stopping
distances.

TOWING TIPS
Before towing, practice turning, stopping, and
backing up the trailer in an area located away from
heavy traffic.
Automatic Transmission
Select the DRIVE range when towing.
The transmission controls include a drive
strategy to avoid frequent shifting when towing.
However, if frequent shifting does occur while in
DRIVE, you can use the AutoStick shift control to
manually select a lower gear.
NOTE:Using a lower gear while operating the vehicle
under heavy loading conditions will improve perfor -
mance and extend transmission life by reducing
excessive shifting and heat buildup. This action will
also provide better engine braking.
Cruise Control — If Equipped
Do not use on hilly terrain or with heavy loads.
When using the Cruise Control, if you experience
speed drops greater than 10 mph (16 km/h),
disengage until you can get back to cruising
speed.
Use Cruise Control in flat terrain and with light
loads to maximize fuel efficiency.
AutoStick

When using the AutoStick shift control, select
the highest gear that allows for adequate
performance and avoid frequent downshifts.
For example, choose “5” if the desired speed can
be maintained. Choose “4” or “3” if needed to
maintain the desired speed.

To prevent excess heat generation, avoid
continuous driving at high RPM. Reduce vehicle
speed as necessary to avoid extended driving at
high RPM. Return to a higher gear or vehicle
speed when grade and road conditions allow.
RECREATIONAL TOWING (BEHIND
MOTORHOME)
Recreational towing (with all four wheels on the
ground, or using a tow dolly) is NOT ALLOWED.
The only acceptable method for towing this vehicle
(behind another vehicle) is on a vehicle trailer with
all four wheels OFF the ground.
CAUTION!
Towing this vehicle in violation of the above
requirements can cause severe transmission
and/or transfer case damage. Damage from
improper towing is not covered under the New
Vehicle Limited Warranty.4

Shallow Standing Water
Although your vehicle is capable of driving through
shallow standing water, consider the following
Warnings and Cautions before doing so.
WARNING!
Driving through standing water limits your
vehicle’s traction capabilities. Do not exceed
5 mph (8 km/h) when driving through
standing water.
Driving through standing water limits your
vehicle’s braking capabilities, which increases
stopping distances. Therefore, after driving
through standing water, drive slowly and
lightly press on the brake pedal several times
to dry the brakes.
Failure to follow these warnings may result in
injuries that are serious or fatal to you, your
passengers, and others around you.
CAUTION!
Always check the depth of the standing water
before driving through it. Never drive through
standing water that is deeper than the bottom
of the tire rims mounted on the vehicle.
Determine the condition of the road or the
path that is under water and if there are any
obstacles in the way before driving through
the standing water.
Do not exceed 5 mph (8 km/h) when driving through standing water. This will minimize
wave effects.
Driving through standing water may cause
damage to your vehicle’s drivetrain compo -
nents. Always inspect your vehicle’s fluids
(i.e., engine oil, transmission, axle, etc.) for
signs of contamination (i.e., fluid that is milky
or foamy in appearance) after driving through
standing water. Do not continue to operate
the vehicle if any fluid appears contaminated,
as this may result in further damage. Such
damage is not covered by the New Vehicle
Limited Warranty.
Getting water inside your vehicle’s engine can
cause it to lock up and stall out, and cause
serious internal damage to the engine. Such
damage is not covered by the New Vehicle
Limited Warranty.
CAUTION!
