Emissions Inspection and Maintenance (I/M) programs
Your vehicle may not pass a state emission inspection if the
malfunction indicator lamp remains on. Contact your Lexus
dealer to check your vehicle's emission control system and
OBD (On-Board Diagnostics) system before taking your
vehicle for the inspection.
See "Emissions Inspection and Maintenance (I/M) programs"
on page 539.
GAUGES, METERS AND SERVICE REMINDER INDICATORS
(i) "ABS" Warning Light
The light comes on when the ignition key is turned to the "ON"
position. If the anti-lock brake system and the brake assist
system work properly, the light turns off after a few seconds.
Thereafter, if either of the systems malfunctions, the light
comes on again.
When the "ABS" 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 the vehicle
stability control system do not operate, but the brake system
still operates conventionally.
When the "ABS" 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.
