Lexus LX 470 1998 Owner's Manual page 215

STARTING AND DRIVING
D Even though the anti−lock brake system is operating, a driver
cannot maintain full control on certain slippery road surfaces,
when cornering at high speeds, or in violent maneuvers.
D Avoid high speeds on wet roads. The anti−lock brake system
cannot eliminate the risk of hydroplaning and loss of tire friction.
Always maintain a safe distance from the vehicle in front of you.
Compared with vehicles not fitted with an anti−lock brake system,
your vehicle may require a longer stopping distance in the following
cases:
D Driving on rough, gravel or snow−covered roads.
D Driving with tire chains installed.
D Driving on roads where the road surface is pitted or has other
differences in surface height.
CAUTION
Do not use tires other than the manufacturer's designated
tires, and do not mix tires or wheels of different sizes. You may
prevent the anti−lock brake system from operating at full
effectiveness.

The light may stay on for about 60 seconds after the engine is started.
It is normal if it goes out after a while.
Depressing the brake pedal repeatedly may turn on the "ABS"
warning light. It is normal if the light goes out after a few seconds.

malfunction somewhere in the parts monitored by the warning light
system. Contact your Lexus dealer as soon as possible to service the
vehicle.
