ignition RAM 1500 2022 Repair Manual

166STARTING AND OPERATING
Aero Height (Lowers the vehicle approximately
0.6 inch [15 mm]) – This position provides
improved aerodynamics by lowering the vehicle.
The vehicle will automatically enter Automatic
Aero Mode when the vehicle speed remains
between 62 mph (100 km/h) and 66 mph
(106 km/h) for greater than 20 seconds or if the
vehicle speed exceeds 66 mph (106 km/h). The
vehicle will return to NRH from Aero Mode if the
vehicle speed remains between 30 mph
(48 km/h) and 35 mph (56 km/h) for greater
than 20 seconds or if the vehicle speed falls
below 30 mph (48 km/h).
NOTE:
Automatic Aero mode will be disabled if a
trailer is detected to prevent shifting loads.
Speed thresholds for raising/lowering the
vehicle automatically at higher speeds only
apply if Automatic Aero Mode is enabled in
your Uconnect Radio settings.
To enter Aero Height manually push the height
selector switch down once from NRH at any
vehicle speed. To return to NRH push the height
selector switch up once while vehicle speed is
less than 56 mph (90 km/h).
NOTE:Automatic Aero Mode may be disabled through
vehicle settings in the instrument cluster display
Ú page 114 or through your Uconnect Radio (if
equipped) Ú page 234.
Entry/Exit Height (Lowers the vehicle approxi -
mately 2 inches [51 mm]) – This position lowers
the vehicle for easier passenger entry and exit
as well as lowering the vehicle for easier loading
and unloading of cargo. To enter Entry/Exit
Mode, push the height selector switch down
once from the NRH while the vehicle speed is
below 33 mph (53 km/h). Once the vehicle
speed goes below 15 mph (24 km/h) the
vehicle height will begin to lower. If the vehicle
speed remains between 15 mph (24 km/h) and
25 mph (40 km/h) for greater than 60 seconds,
or the vehicle speed exceeds 25 mph (40 km/h)
the Entry/Exit change will be canceled. To return
to Normal Height Mode, push the height
selector switch up once while in Entry/Exit or
drive the vehicle over 15 mph (24 km/h).
NOTE:Entry/Exit Height may be achieved using the
Remote Lowering feature on your key fob for easier
entry/loading Ú page 19. The system requires that the ignition be in the ON/
RUN position or the engine running for all user
requested changes. When lowering the vehicle, all
of the doors must be closed. If a door is opened at
any time while the vehicle is lowering, the change
will not be completed until the open door(s) is
closed.
This system uses a lifting and lowering pattern
which keeps the headlights from incorrectly
shining into oncoming traffic. When raising the
vehicle, the rear of the vehicle will move up first
and then the front. When lowering the vehicle, the
front will move down first and then the rear.
After the engine is turned off, it may be noticed that
the air suspension system operates briefly; this is
normal. The system is correcting the position of the
vehicle to ensure a proper appearance.
To assist with changing a spare tire, the air
suspension system has a feature which allows the
automatic leveling to be disabled Ú
page 114.
CAUTION!
When in ENTRY/EXIT Height, be aware of your
surroundings, you may not have the clearance
required for certain areas and vehicle damage
may occur.

OPERATION

Air Suspension Switch

The indicator lamps 1 through 5 will illuminate to
show the current position of the vehicle. Flashing
indicator lamps will show a position which the
system is working to achieve. When raising, if
multiple indicator lamps are flashing, the highest
flashing indicator lamp is the position the system is
working to achieve. When lowering, if multiple
indicators are flashing, the lowest solid indicator
lamp is the position the system is working to
achieve. Pushing the height selector up once will move the
suspension one position higher from the current
position, assuming all conditions are met (i.e.,
ignition in ON/RUN position, engine running, speed
below threshold, etc.). The height selector switch
can be pushed up multiple times, each push will
raise the requested level by one position up to a
maximum position of OR2 or the highest position
allowed based on current conditions (i.e., vehicle
speed, etc.).
Pushing the height selector down once will move
the suspension one position lower from the current
level, assuming all conditions are met (i.e., ignition
in ON/RUN position, engine running, doors closed,
speed below threshold, etc.). The height selector
switch can be pushed down multiple times, each
push will lower the requested level by one position
down to a minimum of Entry/Exit Mode or the
lowest position allowed based on current
conditions (i.e., vehicle speed, etc.).
Automatic height changes will occur based on
vehicle speed and the current vehicle height. The
indicator lamps and instrument cluster display
messages will operate the same for automatic
changes and user requested changes.

178STARTING AND OPERATING
(Continued)
Pushing the on/off button or placing the ignition in
the OFF position, erases the set speed from
memory.
ADAPTIVE CRUISE CONTROL (ACC)
Adaptive Cruise Control (ACC) increases the driving
convenience provided by Cruise Control while
traveling on highways and major roadways.
However, it is not a safety system and not designed
to prevent collisions. The Cruise Control function
performs differently
Ú page 176.
ACC will allow you to keep Cruise Control engaged
in light to moderate traffic conditions without the
constant need to reset your speed. ACC utilizes a
radar sensor and a forward facing camera
designed to detect a vehicle directly ahead of you
to maintain a set speed.
NOTE:
If the ACC sensor detects a vehicle ahead, ACC
will apply limited braking or acceleration (not to
exceed the original set speed) automatically to
maintain a preset following distance, while
matching the speed of the vehicle ahead.
Any chassis/suspension or tire size modifica -
tions to the vehicle will affect the performance
of the Adaptive Cruise Control and Forward Colli -
sion Warning system.
Fixed Speed Cruise Control (ACC not enabled)
will not detect vehicles directly ahead of you.
Always be aware of the feature selected
Ú page 480.
WARNING!
Adaptive Cruise Control (ACC) is a conve -
nience system. It is not a substitute for active
driver involvement. It is always the driver’s
responsibility to be attentive of road, traffic,
and weather conditions, vehicle speed,
distance to the vehicle ahead; and, most
importantly, brake operation to ensure safe
operation of the vehicle under all road condi -
tions. Your complete attention is always
required while driving to maintain safe control
of your vehicle. Failure to follow these warn -
ings can result in a collision and death or
serious personal injury.
The ACC system:
Does not react to pedestrians, oncoming
vehicles, and stationary objects (e.g., a
stopped vehicle in a traffic jam or a
disabled vehicle).
Cannot take street, traffic, and weather
conditions into account, and may be
limited upon adverse sight distance condi -
tions.
Does not always fully recognize complex
driving conditions, which can result in
wrong or missing distance warnings.
Will bring your vehicle to a complete stop
while following a vehicle ahead and hold
your vehicle for approximately three
minutes in the stop position. If the vehicle
ahead does not start moving within three
minutes the parking brake will be acti -
vated, and the ACC system will be
cancelled.
You should switch off the ACC system:
When driving in fog, heavy rain, heavy snow,
sleet, heavy traffic, and complex driving situa -
tions (i.e., in highway construction zones).
When entering a turn lane or highway off
ramp; when driving on roads that are winding,
icy, snow-covered, slippery, or have steep
uphill or downhill slopes.
When towing a trailer up or down steep slopes.
When circumstances do not allow safe driving
at a constant speed.
WARNING!

22_DT_OM_EN_USC_t.book Page 178

STARTING AND OPERATING181
The driver switches ESC to Full Off mode
The braking temperature exceeds normal range
(overheated)
The following conditions will only cancel the ACC
system:
Driver seat belt is unbuckled at low speeds
Driver door is opened at low speeds
To Turn Off
The system will turn off and clear the set speed in
memory if:
The Adaptive Cruise Control (ACC) on/off button
is pushed
The Fixed Speed Cruise Control on/off button is
pushed
The ignition is placed in the OFF position
4WD Low is engaged
To Resume
If there is a set speed in memory, push the RES
(resume) button and then remove your foot from
the accelerator pedal. The instrument cluster
display will show the last set speed.
Resume can be used at any speed above 20 mph
(32 km/h) when only Fixed Speed Cruise Control is
being used. Resume can be used at any speed above 0 mph
(0 km/h) when ACC is active.
NOTE:
If your vehicle is at a standstill for longer than
two seconds, then the driver will either have to
push the RES (resume) button, or apply the
accelerator pedal to reengage the Adaptive
Cruise Control (ACC) to the existing set speed.
ACC cannot be resumed if there is a stationary
vehicle in front of your vehicle in close proximity.
To Vary The Speed Setting
To Increase Or Decrease The Set Speed
After setting a speed, you can increase the set
speed by pushing the SET
(+) button, or decrease
speed by pushing the SET (-) button. U.S. Speed (mph)
Pushing the SET (+)
, or SET (-) button once will
result in a 1 mph speed adjustment. Each
subsequent tap of the button results in an
adjustment of 1 mph.
If the button is continually pushed, the set
speed will continue to adjust in 5 mph incre -
ments until the button is released. The new set
speed is reflected in the instrument cluster
display.
Metric Speed (km/h)
Pushing the SET (+) , or SET (-) button once will
result in a 1 km/h speed adjustment. Each
subsequent tap of the button results in an
adjustment of 1 km/h.
If the button is continually pushed, the set
speed will continue to adjust in 10 km/h incre -
ments until the button is released. The new set
speed is reflected in the instrument cluster
display.
NOTE:When you override and push the SET (+) button or
SET (-) buttons, the new set speed will be the
current speed of the vehicle.
WARNING!
The Resume function should only be used if
traffic and road conditions permit. Resuming a
set speed that is too high or too low for
prevailing traffic and road conditions could
cause the vehicle to accelerate or decelerate too
sharply for safe operation. Failure to follow these
warnings can result in a collision and death or
serious personal injury.

184STARTING AND OPERATING
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
Sensor” 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 an authorized dealer.
Installing a snow plow, front-end protector, an
aftermarket grille or modifying the grille is not
recommended. Doing so may block the sensor
and inhibit ACC/FCW operation.
“CLEAN FRONT WINDSHIELD” WARNING
The “ACC/FCW Limited Functionality Clean Front
Windshield” warning will display and a chime will
sound when conditions temporarily limit system
performance. This most often occurs at times of
poor visibility, such as in snow or heavy rain and
fog. The ACC system may also become temporarily
blinded due to obstructions, such as mud, dirt, or
ice on windshield, driving directly into the sun and
fog on the inside of glass. In these cases, the
instrument cluster display will show “ACC/FCW
Limited Functionality Clean Front Windshield” and
the system will have degraded performance. This message can sometimes be displayed while
driving in adverse weather conditions. The ACC/
FCW system will recover after the vehicle has left
these areas. Under rare conditions, when the
camera is not tracking any vehicles or objects in its
path this warning may temporarily occur.
If weather conditions are not a factor, the driver
should examine the windshield and the camera
located on the back side of the inside rear view
mirror. They may require cleaning or removal of an
obstruction.
When the condition that created limited
functionality is no longer present, the system will
return to full functionality.
NOTE:If the “ACC/FCW Limited Functionality Clean Front
Windshield” message occurs frequently (e.g. more
than once on every trip) without any snow, rain,
mud, or other obstruction, have the windshield and
forward facing camera inspected at an authorized
dealer.
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 temporarily
unavailable. If this occurs, try activating ACC again
later, following an ignition cycle. If the problem
persists, see an authorized dealer.
Precautions While Driving With ACC
NOTE:
Aftermarket add-ons such as snow plows, lift
kits, and brush/grille bars can hinder module
performance. Ensure the radar/camera has no
obstructions in the field of view.
Height modifications can limit module perfor
-
mance and functionality.
Do not put stickers or easy passes over the
camera/radar field of view.
Any modifications to the vehicle that may
obstruct the field of view of the radar/camera
are not recommended.
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. The following are
examples of these types of situations:

22_DT_OM_EN_USC_t.book Page 184

STARTING AND OPERATING187
ParkSense will retain its last known configura -
tion state for the automatic braking function
through ignition cycles.
Trailer hitch ball assembly may cause false
braking events if left attached after towing.
The automatic braking function is intended to
assist the driver in avoiding possible collisions with
detected obstacles when backing up in REVERSE
gear.
NOTE:
The system is provided to assist the driver and
not to substitute the driver.
The driver must stay in full control of the
vehicle's acceleration and braking and is
responsible for the vehicle's movements.
For limitations of this system and usage
precautions, see Ú page 191.
ParkSense will retain the last system state
(enabled or disabled) from the last ignition cycle
when the ignition is placed in the ON/RUN position.
ParkSense can be active only when the gear
selector is in REVERSE or DRIVE. If ParkSense is
enabled while in one of these gears, the system will
remain active until the vehicle speed is increased
to approximately 7 mph (11 km/h) or above. A
warning will appear in the instrument cluster
display indicating the vehicle speed is above ParkSense operating speed while in REVERSE. The
system will become active again if the vehicle
speed is decreased to speeds less than
approximately 6 mph (9 km/h).
PARKSENSE SENSORS
The four ParkSense sensors (six if equipped with
Active Parksense), located in the front fascia/
bumper, monitor the area in front of the vehicle
that is within the sensors’ field of view, and the four
ParkSense sensors, located in the rear fascia/
bumper, monitor the area behind the vehicle that
is within the sensors’ field of view. The front
sensors can detect obstacles from approximately
12 inches (30 cm) up to 47 inches (120 cm) from
the front fascia/bumper. The rear sensors can
detect obstacles from approximately 12 inches
(30 cm) up to 79 inches (200 cm). These distances
depend on the location, type and orientation of the
obstacle in the horizontal direction.
PARKSENSE WARNING DISPLAY
The ParkSense Warning screen is located within
the instrument cluster display Ú
page 114. It
provides visual warnings to indicate the distance
between the rear fascia/bumper and/or front
fascia/bumper and the detected obstacle.
PARKSENSE DISPLAY
The warning display will turn on indicating the
system status when the vehicle is in REVERSE or
when the vehicle is in DRIVE and an obstacle has
been detected.
The system will indicate a detected obstacle by
showing a single arc in the left, right, or center
regions based on the obstacle’s distance and
location relative to the vehicle.
If an obstacle is detected in the center front region,
the display will show a single solid arc in the center
front region with no chime. As the vehicle moves
closer to the obstacle, the display will show the
single arc moving closer to the vehicle and a fast
chime will be heard and will change from fast to
continuous.
If an obstacle is detected in the left and/or right
front region, the display will show a single flashing
arc in the left and/or right front region and will
produce a fast chime. As the vehicle moves closer
to the obstacle, the display will show the single arc
moving closer to the vehicle and the tone will
change from fast to continuous.

the Front or Rear ParkSense switch LED will blink
momentarily, and then the LED will be on.
SERVICE THE PARKSENSE PARK ASSIST
S
YSTEM
During vehicle start up, when the ParkSense
System has detected a faulted condition, the
instrument cluster will actuate a single chime,
once per ignition cycle, and it will display the
"PARKSENSE UNAVAILABLE WIPE REAR
SENSORS", "PARKSENSE UNAVAILABLE WIPE
FRONT SENSORS", or the "PARKSENSE
UNAVAILABLE SERVICE REQUIRED" message for
five seconds. When the gear selector is moved to
REVERSE and the system has detected a faulted condition, the instrument cluster display will
display a "WIPE OFF" message on the
corresponding blocked system while the vehicle is
in REVERSE. The system will continue to provide
arc alerts for the side that is functioning properly.
If "PARKSENSE UNAVAILABLE WIPE REAR
SENSORS" or "PARKSENSE UNAVAILABLE WIPE
FRONT SENSORS" appears in the instrument
cluster display make sure the outer surface and
the underside of the rear fascia/bumper and/or
front fascia/bumper is clean and clear of snow,
ice, mud, dirt or other obstruction and then cycle
the ignition. If the message continues to appear
see an authorized dealer.
NOTE:Water from a car wash or road slush in freezing
weather may also cause sensors to become
blocked.
If the "PARKSENSE UNAVAILABLE SERVICE
REQUIRED" message appears in the instrument
cluster display, see your authorized dealer.
CLEANING THE PARKSENSE SYSTEM
Clean the ParkSense sensors with water, car wash
soap and a soft cloth. Do not use rough or hard
cloths. Do not scratch or poke the sensors.

22_DT_OM_EN_USC_t.book Page 190

STARTING AND OPERATING191
PARKSENSE SYSTEM USAGE
P
RECAUTIONS
NOTE:
Ensure that the front and rear fascias/bumpers
are free of snow, ice, mud, dirt and debris to
keep the ParkSense system operating properly.
Jackhammers, large trucks, and other vibra -
tions could affect the performance of Park -
Sense.
When you turn Front or Rear ParkSense off, the
instrument cluster display will show a vehicle
graphic of the Front or Rear ParkSense on/off
state for two seconds. Furthermore, once you
turn Front or Rear ParkSense off, it remains off
until you turn it on again, even if you cycle the
ignition.
When you move the gear selector to the
REVERSE position and Front or Rear ParkSense
is turned off, the instrument cluster display will
show a vehicle graphic with "OFF" in the corre -
sponding side. This vehicle graphic will be
displayed for as long as the vehicle is in
REVERSE.
ParkSense, when on, will reduce the volume of
the radio when it is sounding a tone.
Clean the ParkSense sensors regularly, taking
care not to scratch or damage them. The
sensors must not be covered with ice, snow,
slush, mud, dirt or debris. Failure to do so can
result in the system not working properly. The
ParkSense system might not detect an obstacle
behind or in front of the fascia/bumper, or it
could provide a false indication that an obstacle
is behind or in front of the fascia/bumper.
Use the ParkSense switch to turn the ParkSense
system off if obstacles such as bicycle carriers,
trailer hitches, etc. are placed near the rear
fascia/bumper. Failure to do so can result in the
system misinterpreting a close obstacle as a
sensor problem, causing the “PARKSENSE
UNAVAILABLE SERVICE REQUIRED” message to
be appear in the instrument cluster display.
ParkSense should be disabled when the tailgate
is in the lowered or open position. A lowered tail -
gate could provide a false indication that an
obstacle is behind the vehicle and could also
cause a false braking event.
The Rear ParkSense system will automatically
disable when the system detects that a trailer
with trailer brakes has been connected to the
Integrated Trailer Brake Module.
The Front ParkSense system will automatically
disable if a snow plow has been connected to
the vehicle.
WARNING!
Drivers must be careful when backing up even
when using ParkSense. Always check carefully
behind your vehicle, look behind you, and be
sure to check for pedestrians, animals, other
vehicles, obstructions, and blind spots before
backing up. You are responsible for safety and
must continue to pay attention to your
surroundings. Failure to do so can result in
serious injury or death.
Before using ParkSense, it is strongly recom -
mended that the ball mount and hitch ball
assembly be disconnected from the vehicle
when the vehicle is not used for towing.
Failure to do so can result in injury or damage
to vehicles or obstacles because the hitch ball
will be much closer to the obstacle than the
rear fascia/bumper when the vehicle sounds
the continuous tone. Also, the sensors could
detect the ball mount and hitch ball assembly,
depending on its size and shape, and give a
false indication that an obstacle is behind the
vehicle, and could cause false braking.
