Dodge 2008 Ram 2500 Automobile User Manual


 
This Anti-lock Brake System is designed to aid the driver
in maintaining vehicle control under adverse braking
conditions. The system operates with a separate com-
puter to modulate hydraulic pressure to prevent wheel
lockup and help avoid skidding on slippery surfaces.
The system’s pump motor runs during an ABS stop to
provide regulated hydraulic pressure. The pump motor
makes a low humming noise during operation. This is
normal.
When you are in a severe braking condition involving
use of the Anti-lock Brake System, you will experience
some pedal drop as the vehicle comes to a complete stop.
This is the result of the system reverting to the base brake
system and is normal.
Engagement of the Anti-lock Brake System may be
accompanied by a pulsing sensation in the brake pedal.
You may also hear a clicking noise. These occurrences are
normal, and indicate that the system is functioning.
ABS Warning Light
The Anti-lock Brake System includes an amber warning
light, located in the instrument cluster. When the light is
illuminated, the Anti-lock Brake System is not function-
ing. The system reverts to standard non-anti-lock brakes.
WARNING!
Pumping of the anti-lock brakes will diminish their
effectiveness and may lead to an accident. Pumping
makes the stopping distance longer. Just press firmly
on your brake pedal when you need to slow down or
stop.
