brake DODGE CHALLENGER 2019 Workshop Manual

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.
Overtake Aid
When driving with ACC engaged and following a vehicle,
the system will provide an additional acceleration up to the
ACC set speed to assist in passing the vehicle. This
additional acceleration is triggered when the driver utilizes
the left turn signal and will only be active when passing on
the left hand side.
Adaptive Cruise Control (ACC) Menu
The instrument cluster display will show the current ACC
system settings. The instrument cluster display is located
in the center of the instrument cluster. The information it
displays depends on ACC system status.
Push the Adaptive Cruise Control (ACC) on/off button
(located on the steering wheel) until one of the following
appears in the instrument cluster display:
Adaptive Cruise Control Off
When ACC is deactivated, the display will read “Adaptive
Cruise Control Off.”
Adaptive Cruise Control Ready
When ACC is activated, but the vehicle speed setting has
not been selected, the display will read “Adaptive Cruise
Control Ready.”
Adaptive Cruise Control Set
When the SET (+) or the SET (-) button (located on the
steering wheel) is pushed, the display will read “ACC
SET.”
When ACC is set, the set speed will show in the instrument
cluster display.
Brake Alert
246 STARTING AND OPERATING

•If the sensor or front end of the vehicle is damaged due
to a collision, see your authorized dealer for service.
• Do not attach or install any accessories near the sensor,
including transparent material or aftermarket grilles.
Doing so could cause an ACC system failure or malfunc-
tion.
When the condition that deactivated the system is no
longer present, the system will return to the “Adaptive
Cruise Control Off” state and will resume function by
simply reactivating it.
NOTE:
• If the “ACC/FCW Unavailable Wipe Front Radar Sen-
sor” message occurs frequently (e.g. more than once on
every trip) without any snow, rain, mud, or other
obstruction, have the radar sensor realigned at your
authorized dealer.
• Installing a snow plow, front-end protector, an aftermar-
ket grille or modifying the grille is not recommended.
Doing so may block the sensor and inhibit ACC/FCW
operation.Service ACC/FCW Warning
If the system turns off, and the instrument cluster displays
“ACC/FCW Unavailable Service Required” or “Cruise/
FCW Unavailable Service Required”, there may be an
internal system fault or a temporary malfunction that
limits ACC functionality. Although the vehicle is still
drivable under normal conditions, ACC will be temporar-
ily unavailable. If this occurs, try activating ACC again
later, following an ignition cycle. If the problem persists,
see your authorized dealer.
Precautions While Driving With ACC
In certain driving situations, ACC may have detection
issues. In these cases, ACC may brake late or unexpectedly.
The driver needs to stay alert and may need to intervene.
Towing A Trailer
Towing a trailer is not advised when using ACC.
248 STARTING AND OPERATING

Offset Driving
ACC may not detect a vehicle in the same lane that is offset
from your direct line of travel, or a vehicle merging in from
a side lane. There may not be sufficient distance to the
vehicle ahead. The offset vehicle may move in and out of
the line of travel, which can cause your vehicle to brake or
accelerate unexpectedly.
Turns And Bends
When driving on a curve with ACC engaged, the system
may decrease the vehicle speed and acceleration for stabil-
ity reasons, with no target vehicle detected. Once the
vehicle is out of the curve the system will resume your
original set speed. This is a part of normal ACC system
functionality.
NOTE:On tight turns ACC performance may be limited.

Using ACC On Hills
When driving on hills, ACC may not detect a vehicle in
your lane. Depending on the speed, vehicle load, traffic
conditions, and the steepness of the hills, ACC perfor-
mance may be limited.
Lane Changing
ACC may not detect a vehicle until it is completely in the
lane in which you are traveling. In the illustration shown,
ACC has not yet detected the vehicle changing lanes and it
may not detect the vehicle until it’s too late for the ACC
system to take action. ACC may not detect a vehicle until it
is completely in the lane. There may not be sufficient
distance to the lane-changing vehicle. Always be attentive
and ready to apply the brakes if necessary.
ACC Hill Example
Lane Changing Example
250 STARTING AND OPERATING

Narrow Vehicles
Some narrow vehicles traveling near the outer edges of the
lane or edging into the lane are not detected until they have
moved fully into the lane. There may not be sufficient
distance to the vehicle ahead.
Stationary Objects And Vehicles
ACC does not react to stationary objects and stationary
vehicles. For example, ACC will not react in situations
where the vehicle you are following exits your lane and the
vehicle ahead is stopped in your lane. Always be attentive
and ready to apply the brakes if necessary.

pushed.
PARKSENSE REAR PARK ASSIST — IF EQUIPPED
The ParkSense Rear Park Assist system provides visual and
audible indications of the distance between the rear fascia
and a detected obstacle when backing up, e.g. during a
parking maneuver.
Refer to “ParkSense System Usage Precautions” in this
section for limitations of this system and recommenda-
tions.
254 STARTING AND OPERATING

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 ensure 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
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
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 vehicles
used for trailer towing.
Manual Transmission — If Equipped
Trailer towing with this vehicle is not recommended.
266 STARTING AND OPERATING

Trailer Sway Control
The trailer sway control 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 Trailer Sway Control (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 the most popular on the market today and they
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 providesfor a more level ride, offering more consistent steering and
brake control thereby enhancing towing safety. The addi-
tion 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!
•
An improperly adjusted Weight Distributing Hitch
system may reduce handling, stability, braking per-
formance, 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.
268 STARTING AND OPERATING

WARNING!
Improper towing can lead to a collision. Follow these
guidelines to make your trailer towing as safe as possible:
•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
overload your vehicle or trailer. Overloading can
cause a loss of control, poor performance or damage
to brakes, axle, engine, transmission, steering, sus-
pension, 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 chockthe trailer wheels.
(Continued)
WARNING! (Continued)
•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.
Perform the maintenance listed in the “Scheduled Servic-
ing”. Refer to “Scheduled Servicing” in “Servicing And
Maintenance” for the proper maintenance intervals. When
towing a trailer, never exceed the GAWR or GCWR ratings.
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.
(Continued)

STARTING AND OPERATING 271

CAUTION!(Continued)
•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.
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. Refer to
“Tires” in “Servicing And Maintenance” for proper tire
inflation procedures.
• 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. Refer to “Tires” in “Servicing And
Maintenance” for the proper inspection procedure. •
When replacing tires, refer to “Tires” in “Servicing And
Maintenance” for the proper tire replacement proce-
dures. Replacing tires with a higher load carrying capac-
ity will not increase the vehicle’s GVWR and GAWR
limits.
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 per-
sonal injury.
• An electronically actuated trailer brake controller is
required when towing a trailer with electronically actu-
ated 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 lbs (453 kg) and required for trailers in excess of
2,000 lbs (907 kg).
