2018 Ram ProMaster City instrument panel

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 hy-
draulic system malfunction or that a problem
with the Brake Booster has been detected by
the Anti-Lock Brake System (ABS) / Elec-
tronic Stability Control (ESC) system. In this
case, the light will remain on until the condi-
tion 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 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 indi-
cated by the Brake Warning Light, which will
turn on when the brake fluid level in the
master cylinder has dropped below a speci-
fied 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.
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 Elec-
tronic 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 re-
quired.
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 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 illumi-
nate, have the light inspected by your autho-
rized dealer.
The light also will turn on when the parking
brake is applied with the ignition switch 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.
— Battery Charge Warning Light
This light illuminates when the battery is not
charging properly. If it stays on while the
engine is running, there may be a malfunc-
tion with the charging system. Contact your
authorized dealer as soon as possible.
This indicates a possible problem with the
electrical system or a related component.
— Door Open Warning Light
This indicator will illuminate when one or
more door(s) are not fully closed.

fluid to boil over, come in contact with hot
engine or exhaust components and cause a
fire.
CAUTION!
Continuous driving with the Transmission
Temperature Warning Light illuminated
will eventually cause severe transmission
damage or transmission failure.
— Seat Belt Reminder Warning Light
When the ignition is first placed in the ON/
RUN or MAR/ON/RUN position, if the driver’s
seat belt is unbuckled, a chime will sound
and the light will turn on. When driving, if the
driver or front passenger seat belt remains
unbuckled, the Seat Belt Reminder Light will
flash or remain on continuously and a chime
will sound. Refer to “Occupant Restraints
Systems” in “Safety” for further information.
— Transmission Fault Warning Light
This light will illuminate (together with a
message in the instrument cluster display
and a buzzer) to indicate a transmission
fault. Contact your authorized dealer if the
message remains after restarting the engine.
— Engine Oil Level Warning Light
This warning light appears on the panel when
the engine oil level falls below the minimum
recommended value. Restore the correct en-
gine oil level or contact your authorized
dealer for service.
Yellow Warning Lights
— Anti-Lock Brake (ABS) Warning
Light
This light monitors the Anti-Lock Brake Sys-
tem (ABS). The light will turn on when the
ignition is placed in the ON/RUN or MAR/ON/
RUN position and may stay on for as long as
four seconds.
If the ABS light remains on or turns on while
driving, then the Anti-Lock portion of the
brake system is not functioning and service is required. However, the conventional brake
system will continue to operate normally if
the brake warning light is not on.
If the ABS light is on, the brake system
should be serviced as soon as possible to
restore the benefits of Anti-Lock Brakes. If
the ABS light does not turn on when the
ignition is placed in the ON/RUN or MAR/ON/
RUN position, have the light inspected by an
authorized dealer.
— Low Fuel Warning Light
When the fuel level reaches approximately
2–6 gal (9–11 L) this light will turn on, and
remain on until fuel is added.
— Generic Warning Light
The Generic Warning Light will illuminate if
any of the following conditions occur: Engine
Oil Pressure Sensor Failure, External Light
Failure, Parking Sensor Failure, DST System
Failure, Stop/Start failure, or Air Bag telltale
recovery.
The telltale will blink in case of Air Bag
Warning Light Failure. Contact an authorized
dealer immediately for service.

CAUTION!
The TPMS has been optimized for the
original equipment tires and wheels.
TPMS pressures and warning have been
established for the tire size equipped on
your vehicle. Undesirable system opera-
tion or sensor damage may result when
using replacement equipment that is not
of the same size, type, and/or style. After-
market wheels can cause sensor damage.
Using aftermarket tire sealants may cause
the Tire Pressure Monitoring System
(TPMS) sensor to become inoperable. Af-
ter using an aftermarket tire sealant it is
recommended that you take your vehicle
to your authorized dealer to have your
sensor function checked.
— Vehicle Security Warning Light
This telltale will illuminate when the vehicle
security alarm system has detected an at-
tempt was made to break into the vehicle.
— Engine Check/Malfunction Indica-
tor Warning Light (MIL)
The Engine Check/Malfunction Indicator
Light (MIL) is a part of an Onboard Diagnostic
System called OBD II that monitors engine
and automatic transmission control systems.
The light will illuminate when the ignition is
in the ON/RUN position before engine start.
If the bulb does not come on when turning
the key from OFF to ON/RUN, have the con-
dition checked promptly.
Certain conditions, such as a loose or missing
gas cap, poor quality fuel, etc., may illumi-
nate the light after engine start. The vehicle
should be serviced if the light stays on
through several typical driving styles. In most
situations, the vehicle will drive normally and
will not require towing.
When the engine is running, the MIL may
flash to alert serious conditions that could
lead to immediate loss of power or severe
catalytic converter damage. The vehicle
should be serviced as soon as possible if this
occurs.
WARNING!
A malfunctioning catalytic converter, as
referenced above, can reach higher tem-
peratures than in normal operating condi-
tions. This can cause a fire if you drive
slowly or park over flammable substances
such as dry plants, wood, cardboard, etc.
This could result in death or serious injury
to the driver, occupants or others.
CAUTION!
Prolonged driving with the Malfunction
Indicator Light (MIL) on could cause dam-
age to the vehicle control system. It also
could affect fuel economy and driveability.
If the MIL is flashing, severe catalytic
converter damage and power loss will soon
occur. Immediate service is required.

ONBOARD DIAGNOSTIC SYSTEM —
OBD II
Your vehicle is equipped with a sophisticated
Onboard Diagnostic system called OBD II.
This system monitors the performance of the
emissions, engine, and transmission control
systems. When these systems are operating
properly, your vehicle will provide excellent
performance and fuel economy, as well as
engine emissions well within current govern-
ment regulations.
If any of these systems require service, the
OBD II system will turn on the Malfunction
Indicator Light (MIL). It will also store diag-
nostic codes and other information to assist
your service technician in making repairs.
Although your vehicle will usually be drivable
and not need towing, see your authorized
dealer for service as soon as possible.
CAUTION!
• Prolonged driving with the MIL on could cause further damage to the emission
control system. It could also affect fuel

economy and driveability. The vehicle
must be serviced before any emissions
tests can be performed.
• If the MIL is flashing while the vehicle is
running, severe catalytic converter dam-
age and power loss will soon occur. Im-
mediate service is required.
Onboard Diagnostic System (OBD
II) Cybersecurity
Your vehicle is required to have an Onboard
Diagnostic system (OBD II) and a connection
port to allow access to information related to
the performance of your emissions controls.
Authorized service technicians may need to
access this information to assist with the
diagnosis and service of your vehicle and
emissions system.

Supplemental Restraint Systems
(SRS)
Some of the safety features described in this
section may be standard equipment on some
models, or may be optional equipment on
others. If you are not sure, ask your autho-
rized dealer.
The air bag system must be ready to protect
you in a collision. The Occupant Restraint
Controller (ORC) monitors the internal cir-
cuits and interconnecting wiring associated
with the electrical Air Bag System Compo-
nents. Your vehicle may be equipped with the
following Air Bag System Components:
Air Bag System Components
• Occupant Restraint Controller (ORC)
• Air Bag Warning Light
• Steering Wheel and Column• Instrument Panel
• Knee Impact Bolsters
• Driver and Front Passenger Air Bags
• Seat Belt Buckle Switch
• Supplemental Side Air Bags
• Supplemental Knee Air Bags
• Front and Side Impact Sensors
• Seat Belt Pretensioners
Air Bag Warning Light
The ORC monitors the readiness of the
electronic parts of the air bag system when-
ever the ignition switch is in the AVV/START
or MAR/ACC/ON/RUN position. If the ignition
switch is in the STOP/OFF/LOCK position the
air bag system is not on and the air bags will
not inflate.
The ORC contains a backup power supply
system that may deploy the air bag system
even if the battery loses power or it becomes
disconnected prior to deployment.
The ORC turns on the Air Bag Warning Light
in the instrument panel for approximately
four to eight seconds for a self-check when the ignition switch is in the MAR/ACC/ON/
RUN position. After the self-check, the Air
Bag Warning Light will turn off. If the ORC
detects a malfunction in any part of the
system, it turns on the Air Bag Warning Light,
either momentarily or continuously. A single
chime will sound to alert you if the light
comes on again after initial startup.
The ORC also includes diagnostics that will
illuminate the instrument panel Air Bag
Warning Light if a malfunction is detected
that could affect the air bag system. The
diagnostics also record the nature of the
malfunction. While the air bag system is
designed to be maintenance free, if any of the
following occurs, have an authorized dealer
service the air bag system immediately.
• The Air Bag Warning Light does not come
on during the four to eight seconds when
the ignition switch is first in the MAR/ACC/
ON/RUN position.
• The Air Bag Warning Light remains on after the four to eight-second interval.
• The Air Bag Warning Light comes on inter- mittently or remains on while driving.

NOTE:
If the speedometer, tachometer, or any en-
gine related gauges are not working, the Oc-
cupant Restraint Controller (ORC) may also
be disabled. In this condition the air bags
may not be ready to inflate for your protec-
tion. Have an authorized dealer service the
air bag system immediately.
WARNING!
Ignoring the Air Bag Warning Light in your
instrument panel could mean you won’t
have the air bag system to protect you in a
collision. If the light does not come on as a
bulb check when the ignition is first
turned on, stays on after you start the
vehicle, or if it comes on as you drive, have
an authorized dealer service the air bag
system immediately.
Front Air Bags
This vehicle has front air bags and lap/
shoulder belts for both the driver and front
passenger. The front air bags are a supple-
ment to the seat belt restraint systems. The
driver front air bag is mounted in the centerof the steering wheel. The passenger front air
bag is mounted in the instrument panel,
above the glove compartment. The words
“SRS AIRBAG” or “AIRBAG” are embossed
on the air bag covers.
WARNING!
• Being too close to the steering wheel or
instrument panel during front air bag
deployment could cause serious injury,
including death. Air bags need room to
inflate. Sit back, comfortably extending
your arms to reach the steering wheel or
instrument panel.
• Never place a rear-facing child restraint
in front of an air bag. A deploying pas-
senger front air bag can cause death or
serious injury to a child 12 years or
younger, including a child in a rear-
facing child restraint.
• Only use a rear-facing child restraint in a
vehicle with a rear seat.
Driver and Passenger Front Air Bag Features
The Advanced Front Air Bag system has mul-
tistage driver and front passenger air bags.
This system provides output appropriate to
the severity and type of collision as deter-
mined by the Occupant Restraint Controller
(ORC), which may receive information from
the front impact sensors (if equipped) or
other system components.

SAFETY
54

The first stage inflator is triggered immedi-
ately during an impact that requires air bag
deployment. A low energy output is used in
less severe collisions. A higher energy output
is used for more severe collisions.
This vehicle may be equipped with a driver
and/or front passenger seat belt buckle
switch that detects whether the driver or front
passenger seat belt is buckled. The seat belt
buckle switch may adjust the inflation rate of
the Advanced Front Air Bags.
WARNING!
• No objects should be placed over or nearthe air bag on the instrument panel or
steering wheel because any such objects
could cause harm if the vehicle is in a
collision 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
WARNING!
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.
Front Air Bag Operation
Front Air Bags are designed to provide addi-
tional 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 de-
celeration over time, vehicle speed and dam-
age by themselves are not good indicators of
whether or not an air bag should have de-
ployed.
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 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 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.
55

rollover or near rollover event, and deploy-
ment of the Side Air Bags is appropriate, the
rollover sensing system will also deploy the
seat belt pretensioners on both sides of the
vehicle.
The SABICs may help reduce the risk of
partial or complete ejection of vehicle occu-
pants through side windows in certain roll-
over or side impact events.
Air Bag System Components
NOTE:
The Occupant Restraint Controller (ORC)
monitors the internal circuits and intercon-
necting wiring associated with electrical Air
Bag System Components listed below:
• Occupant Restraint Controller (ORC)
• Air Bag Warning Light
• Steering Wheel and Column
• Instrument Panel
• Knee Impact Bolsters
• Driver and Front Passenger Air Bags
• Seat Belt Buckle Switch
• Supplemental Side Air Bags• Supplemental Knee Air Bags
• Front and Side Impact Sensors
• Seat Belt Pretensioners
If A Deployment Occurs
The front air bags are designed to deflate
immediately after deployment.
NOTE:
Front and/or side air bags will not deploy in all
collisions. This does not mean something is
wrong with the air bag system.
If you do have a collision which deploys the
air bags, any or all of the following may occur:
• The air bag material may sometimes cause
abrasions and/or skin reddening to the oc-
cupants as the air bags deploy and unfold.
The abrasions are similar to friction rope
burns or those you might get sliding along a
carpet or gymnasium floor. They are not
caused by contact with chemicals. They are
not permanent and normally heal quickly.
However, if you haven’t healed significantly
within a few days, or if you have any blis-
tering, see your doctor immediately. • As the air bags deflate, you may see some
smoke-like particles. The particles are a
normal by-product of the process that gen-
erates the non-toxic gas used for air bag
inflation. These airborne particles may irri-
tate the skin, eyes, nose, or throat. If you
have skin or eye irritation, rinse the area
with cool water. For nose or throat irritation,
move to fresh air. If the irritation continues,
see your doctor. If these particles settle on
your clothing, follow the garment manufac-
turer’s instructions for cleaning.
Do not drive your vehicle after the air bags
have deployed. If you are involved in another
collision, the air bags will not be in place to
protect you.
WARNING!
Deployed air bags and seat belt preten-
sioners cannot protect you in another col-
lision. Have the air bags, seat belt preten-
sioners, and the seat belt retractor
assemblies replaced by an authorized
dealer immediately. Also, have the Occu-
pant Restraint Controller System serviced
as well.
