Driving Your Mazda
The 4WABS operates with a computer
that is able to optimize vehicle control
during braking on varying tire and road
conditions by modulating the brake
pressure at each of the front wheels and
the rear axle. This ''pumping action''
is similar to the driver ''pumping'' the
brakes but happens at a much faster rate.
WARNING
Antilock System:
The antilock system will NOT allow
the vehicle to stop as quickly on wet
or icy surfaces as it would on a dry
surface. Heavy braking on roads
with loose surfaces such as snow or
gravel, or severe pavement irregu-
larities could cause you to lose
control of your vehicle.

t Using antilock brakes
The operation of a vehicle with 4WABS
is very similar to the operation of normal
brakes. However, some differences exist
and are listed below:
S Apply the brake steadily. In the event
of a panic stop, do NOT ''pump'' the
brakes. ''Pumping'' the brakes dur-
ing an antilock stop will diminish
braking effectiveness.
S During an antilock stop, the driver
will notice a brake pedal pulsation
and hear some noise from the engine
compartment. This is an indication
that the 4WABS system is working
correctly and is normal. If the vehicle
has continuous vibration or shudder
in the steering wheel while braking,
the vehicle should be inspected by a
qualified service technician.
WARNING
Antilock System:
The antilock system does not
decrease the time necessary to
apply the brakes or always reduce
stopping distance. Always leave
enough room between your vehicle
and the vehicle in front of you
to stop.
