The light does not come on even if the parking brake is
applied when the ignition switch is in the “ON” position.
The light does not come on even if the ignition switch is

At this time, vibration may occur. However, if you depress the
accelerator pedal more firmly and slowly, you can drive your
vehicle at low speeds. Have your Lexus checked by your
Lexus dealer as soon as possible.

is corrected during low speed driving, the system may not be
recovered
until the engine is stopped and the ignition switch is
turned to “ACC” or “LOCK” position.
Emissions inspection and maintenance (I/M) programs
