2-4. Using other driving systems
CAUTION

When the VSC is activated
The slip indicator light flashes. Always drive carefully. Reckless driving
may cause an accident, resulting in death or serious injury. Exercise particu-
lar care when the indicator light flashes.

When the TRC/VSC systems are turned off
Be especially careful and drive at a speed appropriate to the road conditions.
As these are the systems to help ensure vehicle stability and driving force,
do not turn the TRC/VSC systems off unless necessary.

Replacing tires
Make sure that all tires are of the same size, brand, tread pattern and total
load capacity. In addition, make sure that the tires are inflated to the recom-
mended tire inflation pressure level.
The ABS and VSC systems will not function correctly if different tires are
installed on the vehicle.
Contact any authorized Lexus dealer or repairer, or another duly qualified
and equipped professional, for further information when replacing tires or
wheels.

Handling of tires and suspension
Using tires with any kind of problem or modifying the suspension will
affect the driving assist systems, and may cause a system malfunction.
