STARTING AND OPERATING 307
Normal (Fixed Speed) Cruise Control Mode
In addition to Adaptive Cruise Control mode, a Normal
(Fixed Speed) Cruise Control mode is available for cruising
at fixed speeds. The Normal (Fixed Speed) Cruise Control
mode is designed to maintain a set cruising speed without
requiring the driver to operate the accelerator. Speed Control
can only be operated if the vehicle speed is above 20 mph
(32 km/h).
To change between the different control modes, push the
Adaptive Cruise Control (ACC) on/off button which turns
the ACC on and the Normal (Fixed Speed) Cruise Control
off. Pushing of the Normal (Fixed Speed) Cruise Control on/
off button will result in turning on (changing to) the Normal
(Fixed Speed) Cruise Control mode. To Set A Desired Speed
Turn the Normal (Fixed Speed) Cruise Control on.
When the vehicle has reached the desired speed,
push the RES (+) or SET (-) button and release.
Release the accelerator and the vehicle will operate at the
selected speed. Once a speed has been set a message
“CRUISE CONTROL SET TO MPH (km/h)” will appear
indicating what speed was set. This light will turn on when
the system is turned on via the on/off control. It turns green
when the cruise control is set.

310 STARTING AND OPERATING
ParkSense can be active only when the gear selector is in
REVERSE. If ParkSense is enabled at this gear selector posi -
tion, the system will remain active until the vehicle speed is
increased to approximately 7 mph (11 km/h) or above.
When in REVERSE and above the system's operating speed,
a warning will appear within the instrument cluster display
indicating the vehicle speed is too fast. The system will
become active again if the vehicle speed is decreased to
speeds less than approximately 6 mph (9 km/h).
ParkSense Sensors
For the 3500, 4500 and 5500 Chassis Cab vehicles, the rear
ParkSense sensors are shipped loose. Please refer to the Ram
Body Builders Guide for more information.
The four ParkSense sensors are to be located in the rear
fascia/bumper, and monitor the area behind the vehicle that
is within the sensors’ field of view.
The sensors can detect obstacles from approximately
18 inches (45 cm) up to 79 inches (200 cm) from the rear
fascia/bumper in the horizontal direction, depending on the
location, type and orientation of the obstacle.
NOTE:
If equipped as a dually, the ParkSense system has six rear
sensors to assist in detection around the dually flares. ParkSense Warning Display
The ParkSense Warning screen is located within the instru -
ment cluster display. It provides visual warnings to indicate
the distance between the rear fascia/bumper and the
detected obstacle. Refer to “Instrument Cluster Display” in
“Getting To Know Your Instrument Panel” for further infor -
mation.
ParkSense Display
When the vehicle is in REVERSE, the warning display will
turn on indicating the system status.
The system will indicate a detected obstacle by showing a
single arc in the left and/or right rear regions based on the
object’s distance and location relative to the vehicle.
If an object is detected in the left and/or right rear region, the
display will show a single solid arc in the left and/or right
rear region and the system will produce a tone. As the
vehicle moves closer to the object, the display will show the
single arc moving closer to the vehicle and the tone will
change from a single 1/2 second tone to slow, to fast, to
continuous.

VEHICLE LOADING
Gross Vehicle Weight Rating (GVWR)
The GVWR is the total permissible weight of your vehicle
including driver, passengers, vehicle, options and cargo. The
label also specifies maximum capacities of front and rear axle
systems (GAWR). Total load must be limited so GVWR and
front and rear GAWR are not exceeded.• Never add fuel to the vehicle when the engine is
running. This is in violation of most state and federal
fire regulations and may cause the MIL to turn on.
WARNING!
A fire may result if gasoline is pumped into a portable
container that is inside of a vehicle. You could be
burned. Always place gas containers on the ground
while filling. WARNING! (Continued)
