2015 Ram ProMaster ABS

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 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 four 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.

29. Anti-Lock Brake (ABS) LightThis light monitors the Anti-lock Brake System
(ABS). The light will turn on when the ignition
switch is turned to the ON/RUN position and
may stay on for as long as four seconds.
If the ABS light remains on or turns on while driving, it
indicates that the anti-lock portion of the brake system is
not functioning and that 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 switch is turned to the ON/RUN position, have
the light inspected by an authorized dealer. 30. Vehicle Security Light
If during starting, the key code is not correctly
recognized, the Vehicle Security Light comes
on in the instrument panel. In this case, turn
the key to OFF and then to ON/RUN; if it is
still locked, try again with the other keys that come with
the vehicle. Contact an authorized dealer if you still
cannot start the engine.
If with the engine running the warning light flashes, this
means that the car is not protected by the engine inhibitor
device. Contact an authorized dealer to have all the keys
programmed.
31. Diesel Particulate Filter (DPF)
When the light illuminates solid in the EVIC,
the filter loading is above the specified range.

DEF Fill Procedure
NOTE:Refer to “Fluids, Lubricants, And Genuine Parts”
in “Maintaining Your Vehicle” for the correct fluid type. 1. Remove cap from DEF filler neck (located on drivers
side of the vehicle in the fuel door).
2. Insert DEF fill adapter/nozzle into DEF tank filler neck.
CAUTION!
•To avoid DEF spillage, and possible damage to the
DEF tank from overfilling, do not “top off” the DEF
tank after filling.
• DO NOT OVERFILL. DEF will freeze below 12ºF
(-11ºC). The DEF system is designed to work in
temperatures below the DEF freezing point, how-
ever, if the tank is overfilled and freezes, the
system could be damaged.
• When DEF is spilled, clean the area immediately
with water and use an absorbent material to soak
up the spills on the ground.

WARNING!(Continued)
•To avoid contamination from foreign matter or
moisture, use only new brake fluid or fluid that has
been in a tightly closed container. Keep the master
cylinder reservoir cap secured at all times. Brake
fluid in a open container absorbs moisture from the
air resulting in a lower boiling point. This may
cause it to boil unexpectedly during hard or pro-
longed braking, resulting in sudden brake failure.
This could result in a accident.
•
Overfilling the brake fluid reservoir can result in
spilling brake fluid on hot engine parts, causing the
brake fluid to catch fire. Brake fluid can also damage
painted and vinyl surfaces, care should be taken to
avoid its contact with these surfaces.
•Do not allow petroleum based fluid to contaminate
the brake fluid. Brake seal components could be
damaged, causing partial or complete brake failure.
This could result in an accident.
Automated Manual Transmission
Checking Fluid Levels
To check the gear oil and check/replace the hydraulic
clutch operating system fluid, contact only your autho-
rized dealer.
NOTE: Do not add or use leak detection dye in the
hydraulic clutch operating system fluid.
WARNING!
Used gear oil contains substances that are hazardous
for the environment. It is advisable to have oil
changed by your authorized dealer where used oil
will be disposed of according to the law.
