GAUGES, METERS AND SERVICE REMINDER INDICATORS

(j) VSC TRACº Warning Light
This light warns that there is a problem somewhere in the
following.
Vehicle stability control system
 Active traction control system
 Downhill assist control system
 Hill-start assist control system
The light will come on when the ignition key turned to ONº, and
will go off after a few seconds.
It is not a malfunction that the warning light may stay on for 60
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
systems do not work. However, as conventional braking
operates when applied, there is no problem to continue your
driving.
In the following cases, contact your Lexus dealer:
 The warning light does not come on after the ignition key is
turned to ONº.
 The warning light remains on after the ignition key is turned
to ONº.
 The warning light comes on while driving.
(k) KDSSº Warning Light (vehicles with kinetic
dynamic suspension system)
This light warns that there is a problem somewhere in the
kinetic dynamic suspension system.
The light will come on when the ignition key is turned to the
ONº position and will go off after a few seconds.
If the light comes on while driving, bring your vehicle to your
Lexus dealer as soon as possible and have it checked.
(l) Discharge Warning Light
This light warns that the battery is being discharged.
If it comes on while you are driving, stop the vehicle, turn off the
engine, and check for the cause. Look first at the engine drive
belt.
 If it is loose or broken, the generator will not charge the
battery properly.
 If the belt is O.K., there is a problem somewhere in the
charging system.
The engine ignition will continue to operate, however, until the
battery is discharged. Turn off the air conditioning, blower,
radio, etc., and drive directly to the nearest Lexus dealer or
repair shop.
