seconds after the ignition key is turned to the ONº position.
Depressing the brake pedal repeatedly may turn on the lights.
It is normal if they go out after a few seconds.
There is no problem when the VSC TRACº warning light
comes on when the brake actuator temperature becomes high.
If the light comes on while driving, the above mentioned

(n) Engine Oil Replacement Reminder Light (for vehicles sold in U.S.A.)
This light reminds you when to replace the engine oil.
This light will come on when the ignition key is turned to ONº
and will go off after about a few seconds.
When you drive for about 7200 km (4500 miles) after the

without the engine oil replacement, and if the driving range
exceeds 8000 km (5000 miles), the light will come on after the

system is functioning properly.
If the warning light comes on, stop your vehicle in a safe place
as soon as possible and check that the inflation pressure of all
tires (including the spare tire) is as specified on the tire and
loading information label. (See Checking tire inflation
pressureº on page 578.) The light should go off a few minutes
after the tire pressure is adjusted.
If the warning light blinks, the tire pressure warning system
may be malfunctioning. Contact your Lexus dealer.
