2021 RAM 1500 warning

STARTING AND OPERATING199
The system will cancel the maneuver if the
vehicle speed exceeds 5 mph (7 km/h)
during active steering guidance into the
parking space. The system will provide a
warning to the driver at 3 mph (5 km/h) that
tells them to slow down. The driver is then
responsible for completing the maneuver if
the system is canceled.
If the system is canceled during the
maneuver for any reason, the driver must
take control of the vehicle.
LANESENSE — IF EQUIPPED
LANESENSE OPERATION
The LaneSense system is operational at speeds
above 37 mph (60 km/h) and below 112 mph
(180 km/h). The LaneSense system uses a
forward looking camera to detect lane markings
and measure vehicle position within the lane
boundaries. When both lane markings are detected and the
driver drifts out of the lane (no turn signal
applied), the LaneSense system provides a
haptic warning in the form of torque applied to
the steering wheel, as well as a visual warning
in the instrument cluster display, to prompt the
driver to remain within the lane boundaries.
The driver may manually override the haptic
warning by applying force into the steering
wheel at any time.
When only a single lane marking is detected
and the driver drifts across the lane marking (no
turn signal applied), the LaneSense system
provides a visual warning through the
instrument cluster display to prompt the driver
to remain within the lane.
When only a single lane marking is detected, a
haptic or a torque warning will not be provided.
NOTE:
When operating conditions have been met, the
LaneSense system will monitor if the driver’s
hands are on the steering wheel and provide an
audible and visual warning to the driver if
removed. The system will cancel if the driver
does not return their hands to the wheel.
WARNING!
Drivers must be careful when performing
parallel or perpendicular parking maneuvers
even when using the ParkSense Active Park
Assist system. Always check carefully behind
and in front of your vehicle, look behind and
in front of you, and be sure to check for
pedestrians, animals, other vehicles,
obstructions, and blind spots before backing
up and moving forward. 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.
CAUTION!
The ParkSense Active Park Assist system is
only a parking aid and it is unable to recog
-
nize every obstacle, including small obsta -
cles. Parking curbs might be temporarily
detected or not detected at all. Obstacles
located above or below the sensors will not
be detected when they are in close prox -
imity.
The vehicle must be driven slowly when
using the ParkSense Active Park Assist
system in order to be able to stop in time
when an obstacle is detected. It is recom -
mended that the driver looks over his/her
shoulder when using the ParkSense Active
Park Assist system.4

Left Lane Departure — Only Left Lane Detected

When the LaneSense system is on, the Lane-
Sense Telltale is solid white when only the
left lane marking has been detected and the
system is ready to provide visual warnings in
the instrument cluster display if an uninten -
tional lane departure occurs on the left side.
When the LaneSense system senses the lane
has been approached and is in a lane depar -
ture situation, the visual warning in the
instrument cluster display will show the left
lane line flashing yellow (on/off). The Lane -
Sense telltale changes from solid white to
flashing yellow.

STARTING AND OPERATING201
Left Lane Departure — Both Lane Lines
Detected
When the LaneSense system is on and both
the lane markings have been detected, the
system is "armed" to provide visual warnings
in the instrument cluster display and a torque
warning in the steering wheel if an uninten -
tional lane departure occurs .The lane lines
turn from gray to white and the LaneSense
telltale is solid green.

Lanes Sensed (White Lines) With Green Telltale

When the LaneSense system senses a lane
drift situation, the left lane line turns solid
yellow. The LaneSense telltale changes
from solid green to solid yellow. At this time
torque is applied to the steering wheel in the
opposite direction of the lane boundary. For example: If approaching the left side of
the lane the steering wheel will turn to the
right.

Lane Sensed (Solid Yellow Lane Line) With Solid Yellow Telltale

When the LaneSense system senses the lane
has been approached and is in a lane depar -
ture situation, the left lane line flashes yellow
(on/off). The LaneSense telltale changes
from solid yellow to flashing yellow. At this
time torque is applied to the steering wheel in
the opposite direction of the lane boundary. For example: If approaching the left side of
the lane the steering wheel will turn to the
right.

3. Insert the fuel nozzle fully into the filler pipe – the nozzle opens and holds the flapper
door while refueling. 4. Fill the vehicle with fuel – when the fuel
nozzle “clicks” or shuts off, the fuel tank is
full.
5. Remove the fuel nozzle and close the fuel door.
AVOID USING CONTAMINATED FUEL
Fuel that is contaminated by water or dirt can
cause severe damage to the engine fuel
system. Proper maintenance of the engine fuel
filter and fuel tank is essential Ú page 409.
BULK FUEL STORAGE — DIESEL FUEL
If you store quantities of fuel, good
maintenance of the stored fuel is also essential.
Fuel contaminated with water will promote the
growth of “microbes.” These microbes form
“slime” that will clog the fuel filtration system
and lines. Drain condensation from the supply
tank and change the line filter on a regular
basis.
NOTE:
When a diesel engine is allowed to run out of
fuel, air is pulled into the fuel system.
If the vehicle will not start Úpage 414.

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
“Malfunction 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!
Do not open the high pressure fuel system
with the engine running. Engine operation
causes high fuel pressure. High pressure fuel
spray can cause serious injury or death.
