2-1. Driving procedures
NOTICE
■While driving the vehicle
Do not use the accelerator pedal or depress accelerator and brake pedals together
to hold the vehicle on a hill.
■When parking the vehicle
Always put the shift lever in “P”. Failure to do so may cause the vehicle to move or
the vehicle may accelerate suddenly if the accelerator pedal is accidentally
depressed.
■Avoiding damage to vehicle parts
●Do not turn the steering wheel fully in either direction and hold it there for a long
time. 
Doing so may damage the power steering motor.
●When driving over bumps in the road, drive as slowly as possible to avoid damag-
ing the wheels, underside of the vehicle, etc.
■If you hear a squealing or scraping no ise (brake pad wear limit indicators)
Have your Lexus dealer check and replac e the brake pads as soon as possible.
The rotor damage can result if the pads are not replaced when needed.
Front brake only (GS430): Moderate levels of the brake pad and disc wear allow
enhanced front braking power. As a result , the discs may wear more quickly than
conventional brake discs. Therefore, when replacing the brake pads, Lexus recom-
mends that you also have the th ickness of the discs measured.
It is dangerous to drive the vehicle when the wear limits of the brake pads and/or
that of the brake discs are exceeded.
■If you get a flat tire while driving
A flat or damaged tire may cause the following situations. Hold the steering wheel
firmly and gradually press the brak e pedal to slow down the vehicle.
●It may be difficult to control your vehicle.
●The vehicle will make abnormal sounds.
●The vehicle will behave abnormally.
Replace a flat tire with a new one. ( P. 4 76 )

2-4. Using other driving systems
CAUTION
■The hill-start assist control may not operate effectively when
●On steep inclines.
●On icy surfaces.
■When the VSC is activated
The slip indicator light flashes and a warning buzzer sounds. Always drive carefully.
Reckless driving may cause an accident. Exercise particular care when the indica-
tor light flashes and a buzzer sounds.
■When TRAC and VSC are off
Be especially careful and drive at a speed appropriate to the road conditions. As
these are systems to ensure vehicle stability and driving force, do not turn off TRAC
and VSC 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 ti res are inflated to the specified tire pres-
sure level.
The ABS and VSC will not function correctly if different tires are fitted on the vehi-
cle. 
Contact your Lexus dealer for further info rmation when replacing tires or wheels.
■Handling of tires and suspension (GS430)
Using tires with any kind of problem or modifying the suspension will affect the
VDIM, and may cause the system to malfunction.
