warning lights RAM CHASSIS CAB 2021 Owner's Manual

218STARTING AND OPERATING
NOTE:
With electronically shifted transfer case:
Steps 3 and 4 are requirements that must be
met before pushing the button to shift out of
N (Neutral), and must continue to be met
until the shift has been completed. If any of
these requirements are not met before
pushing the button or are no longer met
during the shift, the N (Neutral) indicator light
will flash continuously until all requirements
are met or until the button is released.
The ignition must be in the ON/RUN mode for
a shift to take place and for the position indi -
cator lights to be operable. If the ignition is
not in the ON/RUN mode, the shift will not
take place and no position indicator lights will
be on or flashing.
A flashing N (Neutral) position indicator light
indicates that shift requirements have not
been met.
DRIVING TIPS
DRIVING ON SLIPPERY SURFACES
Acceleration
Rapid acceleration on snow covered, wet, or
other slippery surfaces may cause the driving
wheels to pull erratically to the right or left. This
phenomenon occurs when there is a difference
in the surface traction under the rear (driving)
wheels.
DRIVING THROUGH WATER
Driving through water more than a few inches/
centimeters deep will require extra caution to
ensure safety and prevent damage to your
vehicle.
Flowing/Rising Water
WARNING!
Rapid acceleration on slippery surfaces is
dangerous. Unequal traction can cause
sudden pulling of the rear wheels. You could
lose control of the vehicle and possibly have a
collision. Accelerate slowly and carefully
whenever there is likely to be poor traction
(ice, snow, wet, mud, loose sand, etc.).
WARNING!
Do not drive on or across a road or path
where water is flowing and/or rising (as in
storm run-off). Flowing water can wear
away the road or path's surface and cause
your vehicle to sink into deeper water.
Furthermore, flowing and/or rising water can
carry your vehicle away swiftly. Failure to
follow this warning may result in injuries that
are serious or fatal to you, your passengers,
and others around you.

SAFETY305
Front Air Bag Operation

Front Air Bags are designed to provide additional
protection by supplementing the seat belts. Front
air bags are not expected to reduce the risk of
injury in rear, side, or rollover collisions. The front
air bags will not deploy in all frontal collisions,
including some that may produce substantial
vehicle damage — for example, some pole
collisions, truck underrides, and angle offset
collisions.

On the other hand, depending on the type and
location of impact, front air bags may deploy in
crashes with little vehicle front-end damage but
that produce a severe initial deceleration.
Because air bag sensors measure vehicle
deceleration over time, vehicle speed and
damage by themselves are not good indicators
of whether or not an air bag should have
deployed.
Seat belts are necessary for your protection in
all collisions, and also are needed to help keep
you in position, away from an inflating air bag.
When the Occupant Restraint Controller (ORC)
detects a collision requiring the front air bags, it
signals the inflator units. A large quantity of
non-toxic gas is generated to inflate the front air
bags.

The steering wheel hub trim cover and the
upper passenger side of the instrument panel
separate and fold out of the way as the air bags
inflate to their full size. The front air bags fully
inflate in less time than it takes to blink your
eyes. The front air bags then quickly deflate
while helping to restrain the driver and front
passenger.
Knee Impact Bolsters
The Knee Impact Bolsters help protect the
knees of the driver and front passenger, and
position the front occupants for improved
interaction with the front air bags.
WARNING!
No objects should be placed over or near
the air bag on the instrument panel or
steering wheel because any such objects
could cause harm if the vehicle is in a colli
-
sion severe enough to cause the air bag to
inflate.

Do not put anything on or around the air bag
covers or attempt to open them manually.
You may damage the air bags and you could
be injured because the air bags may no
longer be functional. The protective covers
for the air bag cushions are designed to open
only when the air bags are inflating.

Relying on the air bags alone could lead to
more severe injuries in a collision. The air
bags work with your seat belt to restrain you
properly. In some collisions, air bags won’t
deploy at all. Always wear your seat belts
even though you have air bags.
WARNING!
Do not drill, cut, or tamper with the knee
impact bolsters in any way.
Do not mount any accessories to the knee
impact bolsters such as alarm lights,
stereos, citizen band radios, etc.

332SAFETY
(Continued)
PERIODIC SAFETY CHECKS YOU SHOULD
M
AKE OUTSIDE THE VEHICLE
Tires
Examine tires for excessive tread wear and
uneven wear patterns. Check for stones, nails,
glass, or other objects lodged in the tread or
sidewall. Inspect the tread for cuts and cracks.
Inspect sidewalls for cuts, cracks, and bulges.
Check the lug nuts/bolt torque for tightness.
Check the tires (including spare) for proper cold
inflation pressure.
Lights
Have someone observe the operation of brake
lights and exterior lights while you work the
controls. Check turn signal and high beam
indicator lights on the instrument panel.
Door Latches
Check for proper closing, latching, and locking.
Fluid Leaks
Check area under the vehicle after overnight
parking for fuel, coolant, oil, or other fluid leaks.
Also, if gasoline fumes are detected or if fuel or
brake fluid leaks are suspected, the cause
should be located and corrected immediately.
ONLY use the passenger’s side floor mat on
the passenger’s side floor area.

ALWAYS make sure objects cannot fall or
slide into the driver’s side floor area when the
vehicle is moving. Objects can become trapped
under accelerator, brake, or clutch pedals and
could cause a loss of vehicle control.

NEVER place any objects under the floor
mat (e.g., towels, keys, etc.). These objects
could change the position of the floor mat
and may cause interference with the accel -
erator, brake, or clutch pedals.

If the vehicle carpet has been removed and
re-installed, always properly attach carpet to
the floor and check the floor mat fasteners
are secure to the vehicle carpet. Fully
depress each pedal to check for interference
with the accelerator, brake, or clutch pedals
then re-install the floor mats.

WARNING! (Continued)
It is recommended to only use mild soap
and water to clean your floor mats. After
cleaning, always check your floor mat has
been properly installed and is secured to
your vehicle using the floor mat fasteners
by lightly pulling mat.
WARNING! (Continued)
