2-4. Using other driving systems
LX570_U (OM60F86U)
■ Propeller shaft noise
If the vehicle height is adjusted on a slope, or with the shift lever in a position other
than “P” or “N” while the vehicle is stopped, you may hear a sound caused by the
expansion and contraction of the propeller shaft. This does not indicate a malfunc-
tion.
■ Continued system operation
Even if the engine is stopped while the vehicle height is being lowered, operation
will continue for up to 30 seconds.
■ 4-Wheel AHC failure warning
If a malfunction occurs in the 4-Wheel AHC or AVS system, normal mode is auto-
matically selected. However, the system may not switch to normal mode depending
on the location of the malfunction.
The warning message is displayed on the multi-information display, and the 4-
Wheel AHC cannot be activated until the malfunction is corrected.
Stop the engine and start it again. If the warning message turns off, the system is
operating correctly. If the warning message continues to be displayed, have the
vehicle checked at your Lexus dealer as soon as possible.
