2016 Ram 3500 Chassis Cab ABS

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 colli-
sions, and also are needed to help keep you in position,
away from an inflating air bag.
When the ORC detects a collision requiring the Ad-
vanced Front Air Bags, it signals the inflator units. A large
quantity of non-toxic gas is generated to inflate the
Advanced Front Air Bags.
The steering wheel hub trim cover and the upper right
side of the instrument panel separate and fold out of the
way as the air bags inflate to their full size. The Advanced
Front Air Bags fully inflate in less time than it takes to
blink your eyes. The 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 occu-
pants for improved interaction with the Advanced Front
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.
Supplemental Side Air Bags — If Equipped
Your vehicle may be equipped with two types of side air
bags:
1.
Supplemental Seat-Mounted Side Air Bags (SABs) (If
Equipped): Located in the outboard side of the front

seats. The SABs are marked with a “SRS AIRBAG” or
“AIRBAG” label sewn into the outboard side of the seats.
The SABs may help to reduce the risk of occupant injury
during certain side impacts and/or vehicle rollover
events, in addition to the injury reduction potential
provided by the seat belts and body structure.When the SAB deploys, it opens the seam on the out-
board side of the seatback’s trim cover. The inflating SAB
deploys through the seat seam into the space between the
occupant and the door. The SAB moves at a very high
speed and with such a high force that it could injure
occupants if they are not seated properly, or if items are
positioned in the area where the SAB inflates. Children
are at an even greater risk of injury from a deploying air
bag.
WARNING!
Do not use accessory seat covers or place objects
between you and the Side Air Bags; the performance
could be adversely affected and/or objects could be
pushed into you, causing serious injury.

72 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

WARNING!
•Your vehicle is equipped with left and right
Supplemental Side Air Bag Inflatable Curtains
(SABICs). Do not stack luggage or other cargo up
high enough to block the deployment of the
SABICs. The trim covering above the side win-
dows where the SABIC and its deployment path
are located should remain free from any obstruc-
tions.
• Your vehicle is equipped with SABICs. In order for
the SABICs to work as intended, do not install any
accessory items in your vehicle which could alter
the roof. Do not add an aftermarket sunroof to your
vehicle. Do not add roof racks that require perma-
nent attachments (bolts or screws) for installation
on the vehicle roof. Do not drill into the roof of the
vehicle for any reason. The SABICs and SABs (“Side Air Bags”) (if equipped
with Side Air Bags) are designed to activate in certain
side impacts and certain rollover events. The Occupant
Restraint Controller (“ORC”) determines whether the
deployment of the Side Air Bags in a particular side
impact or rollover event (if equipped with rollover
sensing) is appropriate, based on the severity and type of
collision. Vehicle damage by itself is not a good indicator
of whether or not Side Air Bags should have deployed.
Side Air Bags are a supplement to the seat belt restraint
system. Side Air Bags deploy in less time than it takes to
blink your eyes. Occupants, including children, who are
up against or very close to Side Air Bags can be seriously
injured or killed. Occupants, including children, should
never lean on or sleep against the door, side windows, or
area where the Side Air Bags inflate, even if they are in an
infant or child restraint.

Brake Warning Light
Red TelltaleLight What It Means
United States
Canada
Brake Warning Light
This light monitors various brake functions, including brake fluid level and parking brake
application. If the brake light turns on it may indicate that the parking brake is applied, that
the brake fluid level is low, or that there is a problem with the anti-lock brake system reser-
voir.
If the light remains on when the parking brake has been disengaged, and the fluid level is at
the full mark on the master cylinder reservoir, it indicates a possible brake hydraulic system
malfunction or that a problem with the Brake Booster has been detected by the Anti-Lock
Brake System (ABS) / Electronic Stability Control (ESC) system. In this case, the light will
remain on until the condition has been corrected. If the problem is related to the brake
booster, the ABS pump will run when applying the brake, and a brake pedal pulsation may
be felt during each stop.
The dual brake system provides a reserve braking capac-
ity in the event of a failure to a portion of the hydraulic
system. A leak in either half of the dual brake system is indicated by the Brake Warning Light, which will turn on
when the brake fluid level in the master cylinder has
dropped below a specified level.

The light will remain on until the cause is corrected.
NOTE:The light may flash momentarily during sharp
cornering maneuvers, which change fluid level condi-
tions. The vehicle should have service performed, and
the brake fluid level checked.
If brake failure is indicated, immediate repair is neces-
sary.
WARNING!
Driving a vehicle with the red brake light on is
dangerous. Part of the brake system may have failed.
It will take longer to stop the vehicle. You could have
a collision. Have the vehicle checked immediately.
Vehicles equipped with the Anti-Lock Brake System
(ABS) are also equipped with Electronic Brake Force
Distribution (EBD). In the event of an EBD failure, the Brake Warning Light will turn on along with the ABS
Light. Immediate repair to the ABS system is required.
Operation of the Brake Warning Light can be checked by
turning the ignition switch from the OFF position to the
ON/RUN position. The light should illuminate for ap-
proximately two seconds. The light should then turn off
unless the parking brake is applied or a brake fault is
detected. If the light does not illuminate, have the light
inspected by an authorized dealer.
The light also will turn on when the parking brake is
applied with the ignition switch in the ON/RUN posi-
tion.
NOTE:
This light shows only that the parking brake is
applied. It does not show the degree of brake application.

Anti-Lock Brake (ABS) Indicator Light
Yellow TelltaleLight What It Means
Anti-Lock Brake (ABS) Indicator Light
After the ignition is turned on, the Anti-Lock Brake System (ABS) light illuminates to indi-
cate function check at vehicle startup. If the light remains on after startup or comes on and
stays on at road speeds, it may indicate that the ABS has detected a malfunction or has be-
come inoperative. The system reverts to standard non-anti-lock brakes.
If both the Brake Warning Light and the ABS Warning Light are on, see an authorized dealer
immediately. Refer to “Anti-Lock Brake System” in “Starting And Operating” for further in-
formation.

BRAKE SYSTEM
If power assist is lost for any reason (for example,
repeated brake applications with the engine off), the
brakes will still function. However, you will experience a
substantial increase in braking effort to stop the vehicle.
If either the front or rear hydraulic system loses normal
braking capability, the remaining system will still func-
tion with some loss of overall braking effectiveness. This
will be evident by increased pedal travel during applica-
tion, greater pedal force required to slow or stop, and
activation of the “Brake Warning Light” and the “ABS
Warning Light” (if equipped) during brake use.
The brake system power assist is provided by a hydro-
boost unit which shares fluid with the power steering
system. You may experience some clicking or hissing
noises from the hydro-boost system during hard braking
conditions.NOTE:
Under cold temperatures, pedal effort will be
higher than normal until the power steering fluid reaches
operating temperature.
