STARTING AND DRIVING
447
CAUTION
Do not rely excessively on the VDIM. Even if the
system is operating, you must always drive carefully
and attentively. Reckless driving will result in an
unexpected accident. If the slip indicator flashes,
special care should be taken.
Only use tires of specified size. The size,
manufacturer, brand and tread pattern for all 4 tires
should be the same. If you use any tires other than
specified, or different types or sizes, the VDIM may
not function correctly. When replacing the tires or
wheels, contact your Lexus dealer.
Do not modify the suspensions. If you modify the
suspensions, the VDIM may not function correctly.
In situations where the road surface is covered with
ice or snow, your vehicle should be fitted with snow
tires or tire chains.
Slip indicator light
When the ignition is turned on, the slip indicator light
comes on. It will go off when the “READY” light comes on.
If the light does not come on when the ignition is turned
on, contact your Lexus dealer.
While the VDIM is using its various functions to stabilize vehicle
motion, the slip indicator in the instrument cluster flashes and
buzzer sounds. Drive carefully when you are in situations
where the indicator flashes. You may feel some vibrations from
the underbody and you may feel some resistance when turning
the steering wheel when the VDIM is using its various
functions.
