Driving
Your vehicle may have an Anti-lock Brake System feature. If it
does, check the Anti-lock Brake System light each time you start
the engine. If it stays on longer than three (3) seconds, shut off
the engine and restart. If it stays on, that means the Anti-lock
Brake feature is not working and should be serviced
immediately to restore the benefits of the Anti-lock feature.
Normal braking is not affected unless the brake warning light is
also lit.
The Anti-lock Brake System has self-check capabilities. As
described above, the system turns on the anti-lock light each
time you start your engine. After the engine is started and the
anti-lock light turns off, the system performs another test the
first time the vehicle reaches 5 mph (8 km/h) (12 mph
[20 km/h] for vehicles equipped with the traction control
system). The system turns on the ABS pump motor for
approximately 1/2 second. At this time, a mechanical noise may
be heard and felt. This is a normal part of the self-check feature.
If a malfunction is found during this check the anti-lock light
will come on.
Ford Motor Company has not found any negative effects of
mobile radio transmitting equipment installed on vehicles with
the ABS system providing that the radio is installed according
to the radio manufacturer's instructions. However, if you have
had a mobile radio transmitter installed and the ABS light
comes on (at any time other than immediately after turning the
key to the ON position) have your mobile radio dealer inspect
the radio installation. Also, if the ABS system is activated other
than during maximum braking, have your mobile radio
installation checked.
