2018 Ram ProMaster City ignition

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

is placed in the PARK position. The light
should turn off. If the light remains on with
the vehicle running, your vehicle will usually
be drivable; however, see an authorized
dealer for service as soon as possible.
If the light continues to flash when the ve-
hicle is running, immediate service is re-
quired and you may experience reduced per-
formance, an elevated/rough idle, or engine
stall and your vehicle may require towing. The
light will come on when the ignition is placed
in the ON/RUN or MAR/ON/RUN position and remain on briefly as a bulb check. If the light
does not come on during starting, have the
system checked by an authorized dealer.
— Engine Temperature Warning Light
This light warns of an overheated engine
condition. If the engine coolant temperature
is too high, this indicator will illuminate and a
single chime will sound. If the temperature
reaches the upper limit, a continuous chime
will be sound for four minutes or until the
engine is allowed to cool whichever comes
first.
If the light turns on while driving, safely pull
over and stop the vehicle. If the A/C system is
on, turn it off. Also, shift the transmission
into NEUTRAL and idle the vehicle. If the
temperature reading does not return to nor-
mal, turn the engine off immediately and call
for service. Refer to “If Your Engine Over-
heats” in “In Case Of Emergency” for further
information.
— Oil Pressure Warning Light
This light indicates low engine oil pressure. If
the light turns on while driving, stop the
vehicle and shut off the engine as soon as
possible. A chime will sound when this light
turns on.
Do not operate the vehicle until the cause is
corrected. This light does not indicate how
much oil is in the engine. The engine oil level
must be checked under the hood.
— Transmission Temperature Warning
Light — If Equipped
This light indicates that there is excessive
transmission fluid temperature that might
occur with severe usage such as trailer tow-
ing. If this light turns on, stop the vehicle and
run the engine at idle or slightly faster, with
the transmission in PARK or NEUTRAL, until
the light turns off. Once the light turns off,
you may continue to drive normally.
WARNING!

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.

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.

— Electronic Stability Control (ESC)
Warning Light — If Equipped
The “ESC Indicator Light” in the instrument
cluster will come on when the ignition is
placed in the ON/RUN or MAR/ON/RUN po-
sition, and when ESC is activated. It should
go out with the engine running. If the “ESC
Indicator Light” comes on continuously with
the engine running, a malfunction has been
detected in the ESC system. If this light
remains on after several ignition cycles, and
the vehicle has been driven several miles
(kilometers) at speeds greater than 30 mph
(48 km/h), see your authorized dealer as soon
as possible to have the problem diagnosed
and corrected.
• The “ESC Off Indicator Light” and the “ESC Indicator Light” come on momen-
tarily each time the ignition is placed in the
ON/RUN or MAR/ON/RUN position.
• Each time the ignition is turned to ON/RUN or MAR/ON/RUN, the ESC system will be
on, even if it was turned off previously. • The ESC system will make buzzing or click-
ing sounds when it is active. This is normal;
the sounds will stop when ESC becomes
inactive.
• This light will come on when the vehicle is in an ESC event.
— Electronic Stability Control (ESC) Off
Warning Light — If Equipped
This light indicates the Electronic Stability
Control (ESC) is off.
Each time the ignition is turned to ON/RUN
or ACC/ON/RUN, the ESC system will be on,
even if it was turned off previously.
Yellow Indicator Lights
— Cold Start Inhibitor — If Equipped
This vehicle will inhibit engine cranking when
the ambient temperature is less than –22° F
(–30° C) and the oil temperature sensor read-
ing indicates an engine block heater has not
been used. The Cold Start Inhibitor light will
flash during in cold weather for up to 10 sec-
onds. If equipped with a block heater harness the
message "Engine Heater Recommended",
will be displayed in the instrument cluster
when the ambient temperature is below 5°F
(-15° C) at the time the engine is shut off as
a reminder to avoid possible crank delays at
the next cold start.
Green Indicator Lights
— Turn Signal Indicator Lights
The turn signal arrows will flash indepen-
dently when left or right turn signals are
selected. Turn signals can be activated when
the multifunction lever is moved down (left)
or up (right).
NOTE:
• A continuous chime will sound if the ve-
hicle is driven more than 1 mile (1.6 km)
with either turn signal on.
• Check for an inoperative outside light bulb if either indicator flashes at a rapid rate.

Tire Pressure Monitoring Low Pressure
Warnings
The Tire Pressure Monitoring Telltale Light
will illuminate in the instrument cluster, an
audible chime will be activated, and the
“Check tire pressure” text message will dis-
play when one or more of the four active road
tire pressures are low. Should this occur, you
should stop as soon as possible, check the
inflation pressure of each tire on your vehicle,
and inflate each tire to the vehicle’s recom-
mended cold placard pressure value. The
system will automatically update and the Tire
Pressure Monitoring Light will extinguish
once the updated tire pressures have been
received. The vehicle may need to be driven
for up to 20 minutes above 15 mph
(24 km/h) to receive this information.
Check TPMS Warnings
The Tire Pressure Monitoring Telltale Light
will flash on and off for 75 seconds and
remain on solid when a system fault is de-
tected, an audible chime will be activated
and a proper text message will be displayed.
If the ignition key is cycled, this sequence
will repeat providing the system fault stillexists. The Tire Pressure Monitoring Telltale
Light will turn off when the fault condition no
longer exists. A system fault can occur with
any of the following scenarios:
1. Jamming due to electronic devices or driv-
ing next to facilities emitting the same
radio frequencies as the TPM sensors.
2. Installing some form of aftermarket win- dow tinting that affects radio wave
signals.
3. Snow or ice around the wheels or wheel housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPM sensors.
NOTE:
Your vehicle can be equipped with either Tire
Service Kit, compact spare tire or regular size
spare tire (with or without original TPMS
sensor).
1. Tire Service Kit (original tire sealant – if equipped): After fixing the punctured tire
with original tire sealant, the original situ-
ation will be restored, so system will turn
off the telltale during the normal drive. 2. Compact Spare Tire – if equipped: The
compact spare wheel is not equipped with
TPMS sensor. So when mounted, during
the normal drive the system will turn on
the telltale (flashing for approximately
75 sec. then remains solid). This condi-
tion persists until a wheel equipped with
original TPMS sensor has been mounted
on the vehicle.
3. Regular size spare tire (not equipped with TPMS sensor): When mounted, during the
normal drive the system will turn on the
telltale (flashing for approximately
75 sec. then remains solid). This condi-
tion persists until a wheel equipped with
original TPMS sensor has been mounted
on the vehicle. Then the system will be
restored and the telltale will turn off dur-
ing the normal drive.
4. Regular size spare tire (equipped with TPMS sensor): When mounted, the tell-
tale will turn off during the normal drive.
5. In all the above cases please check the replacement tire inflation pressure before
driving your vehicle.
SAFETY

6. All occupants should always wear their lapand shoulder belts properly.
7. The driver and front passenger seats should be moved back as far as practical
to allow the front air bags room to inflate.
8. Do not lean against the door or window. If your vehicle has side air bags, and deploy-
ment occurs, the side air bags will inflate
forcefully into the space between occu-
pants and the door and occupants could
be injured.
9. If the air bag system in this vehicle needs to be modified to accommodate a dis-
abled person, refer to “Customer Assis-
tance” for customer service contact
information.
WARNING!
• Never place a rear-facing child restraintin 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.
WARNING!
• Only use a rear-facing child restraint in avehicle with a rear seat.
Seat Belt Systems
Buckle up even though you are an excellent
driver, even on short trips. Someone on the
road may be a poor driver and could cause a
collision that includes you. This can happen
far away from home or on your own street.
Research has shown that seat belts save
lives, and they can reduce the seriousness of
injuries in a collision. Some of the worst
injuries happen when people are thrown from
the vehicle. Seat belts reduce the possibility
of ejection and the risk of injury caused by
striking the inside of the vehicle. Everyone in
a motor vehicle should be belted at all times.
Enhanced Seat Belt Use Reminder System
(BeltAlert)
Driver And Passenger BeltAlert — If Equipped
BeltAlert is a feature intended to remind
the driver and outboard front seat passenger
(if equipped with outboard front passenger seat BeltAlert) to buckle their seat belts. The
Belt Alert feature is active whenever the igni-
tion switch is in the START or ON/RUN posi-
tion.
Initial Indication
If the driver is unbuckled when the ignition
switch is first in the START or ON/RUN posi-
tion, a chime will signal for a few seconds. If
the driver or outboard front seat passenger (if
equipped with outboard front passenger seat
BeltAlert) is unbuckled when the ignition
switch is first in the START or ON/RUN posi-
tion the Seat Belt Reminder Light will turn on
and remain on until both outboard front seat
belts are buckled. The outboard front passen-
ger seat BeltAlert is not active when an out-
board front passenger seat is unoccupied.
BeltAlert Warning Sequence
The BeltAlert warning sequence is activated
when the vehicle is moving above a specified
vehicle speed range and the driver or out-
board front seat passenger is unbuckled (if
equipped with outboard front passenger seat
BeltAlert) (the outboard front passenger seat
BeltAlert is not active when the outboard
front passenger seat is unoccupied). The

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.
