Ignition Ram 1500 2020 Owners Manual

340 STARTING AND OPERATING
To Accelerate For Passing
Press the accelerator as you would normally. When the pedal
is released, the vehicle will return to the set speed.
To Resume Speed
To resume a previously set speed, push the RES button and
release. Resume can be used at any speed above 20 mph
(32 km/h).
To Deactivate
A soft tap on the brake pedal, pushing the CANC (cancel)
button, or normal brake pressure while slowing the vehicle
will deactivate the speed control without erasing the set
speed from memory.
Pushing the on/off button or placing the ignition in the OFF
position, erases the set speed from memory.
Using Speed Control On Hills
The transmission may downshift on hills to maintain the
vehicle set speed.
NOTE:
The Speed Control system maintains speed up and down
hills. A slight speed change on moderate hills is normal.On steep hills, a greater speed loss or gain may occur so it
may be preferable to drive without Speed Control.
ADAPTIVE CRUISE CONTROL (ACC) — IF EQUIPPED
Adaptive Cruise Control (ACC) increases the driving conve
-
nience provided by cruise control while traveling on high -
ways and major roadways. However, it is not a safety system
and not designed to prevent collisions. Speed Control func-
tion performs differently. Please refer to the proper section
within this chapter.
ACC will allow you to keep cruise control engaged in light
to moderate traffic conditions without the constant need to
reset your cruise control. ACC utilizes a radar sensor and a
forward facing camera designed to detect a vehicle directly
ahead of you.
NOTE:
• If the sensor does not detect a vehicle ahead of you, ACC will maintain a fixed set speed.
• If the ACC sensor detects a vehicle ahead, ACC will apply limited braking or accelerate (not to exceed the original set
speed) automatically to maintain a preset following
distance, while matching the speed of the vehicle ahead.

346 STARTING AND OPERATING
To Turn Off
The system will turn off and clear the set speed in memory if:
• The Adaptive Cruise Control (ACC) on/off button ispushed.
• The Normal (Fixed Speed) Cruise Control on/off button is pushed.
• The ignition is placed in the OFF position.
• You switch to Four-Wheel Drive Low.
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 display the last set speed.
NOTE:
• If your vehicle stays at standstill for longer than two seconds, then the driver will either have to push the RES
(resume) button, or apply the accelerator pedal to reen -
gage 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 Speed
While ACC is set, you can increase the set speed by pushing
the SET (+) button.
The speed increment shown is dependent on the chosen
speed unit of U.S. (mph) or Metric (km/h):
U.S. Speed (mph)
• Pushing the SET (+) button once will result in a 1 mph
increase in set speed. Each subsequent tap of the button
results in an increase of 1 mph.
• If the button is continually pushed, the set speed will continue to increase in 5 mph increments until the button
is released. The increase in set speed is reflected in the
instrument cluster display.
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.

able. 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.
NOTE:
• Aftermarket add-ons such as snow plows, lift kits, andbrush/grille bars can hinder module performance. Ensure
the radar/camera has no obstructions in the field of view.
• Height modifications can limit module performance 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.
Cleaning Instructions
Dust and dirt can accumulate on the cover and block the
camera lens. Clean the camera lens with a soft microfiber
cloth, being careful not to damage or scratch the module. Towing A Trailer
ACC while towing a trailer is recommended only with an
Integrated Trailer Brake Controller. Aftermarket trailer
brake controllers will not activate the trailer brakes when
ACC is braking.
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 accel
-
erate unexpectedly.

PARKSENSE FRONT AND REAR PARK ASSIST
The ParkSense Park Assist system provides visual and
audible indications of the distance between the rear and/or
front fascia and a detected obstacle when backing up or
moving forward (e.g. during a parking maneuver). If your
vehicle is equipped with the automatic braking function, the
vehicle brakes may be automatically applied and released
when performing a reverse parking maneuver if the system
detects a possible collision with an obstacle.
