Toyota Previa Owner's Manual page 140

Always maintain a safe distance from the
vehicle in front of you. Compared with ve-
hicles not fitted with an anti-lock brake
system, your vehicle may require a longer
stopping distance in the following cases:
S Driving on rough, gravel or snow-cov-
ered roads.
S Driving with tire chains installed.
S Driving on roads where the road sur-
face is pitted or has other differences
in surface height.
"ABS" warning light
This light comes on when the ignition key
is turned to the "ON" position. After about
3 seconds, the light will go off.
If either of the following conditions occurs,
this indicates a malfunction somewhere in
the parts monitored by the warning light
system. Contact your Toyota dealer as
soon as possible to service the vehicle.
S The light does not come on as de-
scribed above, or remains on.
S The light comes on while driving.
Even if the anti-lock brake system should
fail, the brake system will still operate con-
ventionally. However, when the 'ABS''
warning light is on (and the brake system
warning light is off), the anti-lock brake
system is not assisting brake perfor-
mance so that the wheels can lock-up
during sudden braking or braking on slip-
pery road surfaces. Have your vehicle
checked by your Toyota dealer as soon as
possible
