2017 RAM CHASSIS CAB ABS

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 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 occu-
pants for improved interaction with the 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 is 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.
Supplemental Seat-Mounted Side Air Bag Label 2THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 59

The SABs may help reduce the risk of head or other injuries
to front and rear seat outboard occupants in 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 outboard
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.
2. Supplemental Side Air Bag Inflatable Curtains
(SABICs) (If Equipped): Located above the side win-
dows. The trim covering the SABICs is labeled “SRS
AIRBAG” or “AIRBAG.” SABICs may help reduce the risk of head or other injuries
to front and rear seat outboard occupants in certain side
impacts and/or vehicle rollover events, in addition to the
injury reduction potential provided by the seat belts and
body structure.
The SABICs deploy downward, covering the side win-
dows. An inflating SABIC pushes the outside edge of the
trim out of the way and covers the window. The SABICs
inflate with enough force to injure occupants if they are not
belted and seated properly, or if items are positioned in the
area where the SABICs inflate. Children are at an even
greater risk of injury from a deploying air bag. Supplemental Side Air Bag Inflatable Curtain (SABIC)
Label Location60 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

WARNING!• Do not stack luggage or other cargo up high enough
to block the deployment of the SABICs. The trim
covering above the side windows where the SABIC
and its deployment path are located should remain
free from any obstructions.
• 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 permanent 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 Re-
straint Controller (ORC) determines whether the deploy-
ment of the Side Air Bags in a particular side impact or
rollover event (if equipped with rollover sensing) is appro-
priate, 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.
WARNING!• 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 win-
dows, or area where the side air bags inflate, even if
they are in an infant or child restraint.
• Seat belts (and child restraints where appropriate)
are necessary for your protection in all collisions.
They also help keep you in position, away from an
inflating Side Air Bag. To get the best protection
from the Side Air Bags, occupants must wear their
seat belts properly and sit upright with their backs
against the seats. Children must be properly re-
strained in a child restraint or booster seat that is
appropriate for the size of the child.
• Side Air Bags need room to inflate. Do not lean
against the door or window. Sit upright in the center
of the seat. (Continued) 2THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 61

Brake Warning Light
Red Telltale
Light What It Means
English
Metric Brake Warning Light
This light monitors various brake functions, including brake fluid level and parking brake appli-
cation. 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 reservoir.
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 mal-
function or that a problem with the Brake Booster has been detected by the Anti-Lock Brake Sys-
tem (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.
NOTE: Brake Warning Light may illuminate due to excessive wear to brake pads.
The dual brake system provides a reserve braking capacity
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 conditions.
The vehicle should have service performed, and the brake
fluid level checked.
If brake failure is indicated, immediate repair is necessary.198 UNDERSTANDING YOUR INSTRUMENT PANEL

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).
CAUTION!In the event of an EBD failure, the Brake Warning
Light will turn on along with the ABS Light. Immedi-
ate repair to the ABS system is required. Operation of the Brake Warning Light can be checked by
placing the ignition in the ON/RUN position. The light
should illuminate for approximately 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 placed in the ON/RUN position.
NOTE: This light shows only that the parking brake is
applied. It does not show the degree of brake application.
Vehicle Security Warning Light — If Equipped
Red Telltale
Light What It Means
Vehicle Security Warning Light — If Equipped

Anti-Lock Brake (ABS) Indicator Light
After the ignition is turned on, the Anti-Lock Brake System (ABS) light illuminates to indicate
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 become 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 im-
mediately. Refer to “Anti-Lock Brake System” in “Starting And Operating” for further informa-

WARNING! (Continued)• Be sure the parking brake is fully disengaged before
driving; failure to do so can lead to brake failure and
a collision.
• Always fully apply the parking brake when leaving
your vehicle or it may roll and cause damage or
injury. Also, be certain to leave an automatic trans-
mission in PARK, a manual transmission in RE-
VERSE or first gear. Failure to do so may cause the
vehicle to roll and cause damage or injury.
CAUTION!If the “Brake Warning Light” remains on with the
parking brake released, a brake system malfunction is
indicated. Have the brake system serviced by an au-
thorized dealer immediately.
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 in-
crease in braking effort to stop the vehicle. If either the front or rear hydraulic system loses normal
braking capability, the remaining system will still function
with some loss of overall braking effectiveness. This will be
evident by increased pedal travel during application,
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.
Hydraulic Brake Assist
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.352 STARTING AND OPERATING
