and slowly, you can drive your vehicle at low speeds. Have
your Lexus checked by your Lexus dealer as soon as possible.

comes on again.
When the ªABSº warning light is on (and the brake system
warning light is off), the anti±lock brake system, the brake
assist system, the traction control system and/or the vehicle
skid control system do/does not operate, but the brake system
still operates conventionally.
When the ªABSº warning light is on (and the brake system
warning light is off), the anti±lock brake system does not
operate so that the wheels could lock up during a sudden
braking or braking on slippery road surfaces.
If either of the following conditions occurs, this indicates
a malfunction somewhere in the parts monitored by the
warning light system. Contact your Lexus dealer as soon
as possible to service the vehicle.
