2-4. Using other driving systems
■ EPS operation sound
When the steering wheel is operated, a motor sound (whirring sound) may be
heard. This does not indicate a malfunction.
■ Reduced effectiveness of the EPS system
The effectiveness of the EPS system is reduced to prevent the system from over-
heating when there is frequent steering input over an extended period of time. The
steering wheel may feel heavy as a result. Should this occur, refrain from excessive
steering input or stop the vehicle and turn the engine off. The EPS system should
return to normal within 10 minutes.
■ If the slip indicator comes on
It may indicate a malfunction in the VSC or TRAC function.
Contact your Lexus dealer.
■ The ABS does not operate effectively when
● The limits of tire gripping performance have been exceeded (such as excessively
worn tires on a snow covered road).
● The vehicle hydroplanes while driving at high speed on the wet or slick road.
■ Stopping distance when the ABS is operating may exceed that of normal condi-
tions
The ABS is not designed to shorten the vehicle’s stopping distance. Always main-
tain a safe distance from the vehicle in front of you, especially in the following situa-
tions.
● When driving on dirt, gravel or snow-covered roads
● When driving with tire chains
● When driving over bumps in the road
● When driving over roads with potholes or roads with uneven roads
