●A sensor may be cove red with ice, snow,
dirt, etc. Remove the ice, snow, dirt, etc.,
from the sensor to return the system to
normal.
Also, due to ice forming on a sensor at
low temperatures, a warning message
may be displayed or the sensor may not
be able to detect an object. Once the ice
melts, the system wi ll return to normal.
●The surrounding area of the sensors on
the bumper may be dirty, or a sensor may
be covered with ice, snow, dirt, etc. In this
case, remove the ice, snow, dirt, etc. from
the sensor or its surrounding area on the
bumper to return the system to a normal
state. At a low temperature, a warning
message may be displayed or an object
may not be detected due to freezing of
the sensor. Once the ice melts, the sys-
tem will return to normal.
●If this message continues to be displayed
even after cleaning the sensor, or is dis-
played even though the sensor is clean,
have the vehicle inspected by your Lexus
dealer.
●Initialization may not have been per-
formed after a 12-volt battery terminal
was disconnected and reconnected. Ini-
tialize the system. ( P.247)

WARNING
●When driving with tire chains
●When driving over bumps in the road
●When driving over roads with potholes
or uneven surfaces
■TRAC/VSC may not operate effec-
tively when
Directional control and power may not
be achievable while driving on slippery
road surfaces, even if the TRAC/VSC
system is operating.
Drive the vehicle carefully in conditions
where stability and power may be lost.
■Active Cornering Assist does not
operate effectively when
●Do not rely solely upon Active Cor-
nering Assist. Active Cornering Assist
may not operate effectively when
accelerating down slopes or driving on
slippery road surfaces.
●When Active Cornering Assist fre-
quently operates, Active Cornering
Assist may temporarily stop operating
to ensure proper operation of the
brakes, TRAC, VSC.
■Hill-start assist control does not oper-
ate effectively when
●Do not overly rely on the hill-start
assist control. Hill-start assist control
may not operate effectively on steep
inclines and roads covered with ice.
●Unlike the parking brake, hill-start
assist control is not intended to hold
the vehicle stationary for an extended
period of time. Do not attempt to use
hill-start assist control to hold the vehi-
cle on an incline, as doing so may lead
to an accident.
■When the TRAC/ABS/VSC is acti-
vated
The slip indicator light flashes. Always
drive carefully. Re ckless driving may
cause an accident. Exercise particular
care when the indicator light flashes.
■When the TRAC/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 TRAC/VSC systems off unless
necessary.
■Secondary Collision Brake
Do not overly rely on the Secondary Col-
lision Brake. This system is designed to
help reduce the possibility of further
damage due to a secondary collision,
however, that effect changes according
to various conditions. Overly relying on
the system may result in death or serious
injury.
■Replacing tires
Make sure that all ti res are of the speci-
fied 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, TRAC and VSC systems will
not function correctly if different tires are
installed on the vehicle.
Contact your Lexus dealer for further
information when replacing tires or
wheels.
■Handling of tires and the suspension
Using tires with any kind of problem or
modifying the suspensi on will affect the
driving assist systems, and may cause a
system to malfunction.

■Ventilation and air conditioning odors
●To let fresh air in, set the air conditioning
system to the outside air mode.
●During use, various odors from inside and
outside the vehicle may enter into and
accumulate in the air conditioning sys-
tem. This may then cause odor to be
emitted from the vents.
●To reduce potential odors from occur-
ring:
• It is recommended that the air condition- ing system be set to outside air mode
prior to turning the vehicle off.
• The start timing of the blower may be delayed for a short pe riod of time imme-
