Slip indicator light
If the vehicle is going to skid during driving, the slip
indicator light flashes and an alarm sounds.
The vehicle skid control activates when the vehicle
speed is about more than 15 km/h (9 mph).
Depressing the brake pedal repeatedly causes a small
noise from the engine compartment. This is a pump
pulsating sound of the brake system and it is not a
malfunction.
You may hear a sound in the engine compartment for a
few seconds when the engine is started or just after the
vehicle is started. This means that the vehicle skid
control is in the self±check mode and does not indicate
a malfunction.

slip indicator light flashes, sounding an alarm,
special care should be taken while driving.

manufacturer, brand and tread pattern for all 4 tires
should be the same. If you use the tires other than
specified, or different type or size, the vehicle skid
control system may not function correctly. When
replacing the tires or wheels, contact your Lexus
dealer.
