motor sound (whirring sound) may be heard. This does not indicate a malfunction.
■Automatic reactivation of TRC and VSC systems
After turning the TRC and VSC systems off, the systems will be automatically re-
enabled in the following situations:
●When the engine switch
is turned off
●If only the TRC system is turned off, the
TRC will turn on when vehicle speed increases
If both the TRC and VSC systems are turned off, automatic re-enabling will not occur when vehicle speed increases.
■Secondary Collision Brake operating
conditions
The vehicle speed is approximately 10 km/h
(6 mph) or more and the airbag sensor detects a collision. (The Secondary Colli-sion Brake will not operate when the vehicle
speed is below approximately 10 km/h [6 mph].)
■Secondary Collision Brake automatic
cancellation
The Secondary Collision Brake is automati-
cally canceled in the following situations:
●The vehicle speed drops below approxi-
mately 10 km/h (6 mph)
●A certain amount of time elapses during
operation

met, the emergency brake signal will oper- ate:
●The emergency flashers are off.
●Actual vehicle speed is over 55 km/h
(35 mph).
●The brake pedal is depressed in a manner
that cause the system to judge from the vehicle deceleration that this is a sudden braking operation.
■Automatic system cancelation of emer-
gency brake signal
The emergency brake sign al will turn off in
any of the following situations:
●The emergency flashers are turned on.
●The brake pedal is released.
●The system judges from the vehicle deceleration that is not a sudden braking
operation.

4-5. Using the driving support systems
WARNING
■Stopping distance when the ABS is operating may exceed that of normal conditions
The ABS is not designed to shorten the vehicle’s stopping distance. Always main-
tain a safe distance from the vehicle in front of you, especially in the following situations:
●When driving on dirt, gravel or snow-
covered roads
●When driving with tire chains
●When driving over bumps in the road
●When driving over roads with potholes or uneven surfaces
■TRC/VSC may not operate effec-tively when
Directional control and power may not be achievable while driving on slippery
road surfaces, even if the TRC/VSC sys- tem is operating.
Drive the vehicle carefully in conditions where stability and power may be lost.
■Hill- start assist control does not operate effectively when
●Do not overly rely on 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 TRC/VSC/ABS is acti-vated
The slip indicator light flashes. Always drive carefully. Reckless driving may
cause an accident. Exercise particular 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 dr iving force, do not turn the TRC/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 tires 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, TRC and VSC systems will not
function correctly if different tires are installed on the vehicle.
Contact any authorized Lexus retailer or Lexus authorized repairer, or any reliable
repairer for further information when replacing tires or wheels.
■Handling of tires and the suspension
Using tires with any kind of problem or modifying the suspension will affect the driving assist systems, and may cause a
system to malfunction.

4-6. Driving tips
Perform the following according to the
driving conditions:
 Do not try to forcibly open a window
or move a wiper that is frozen. Pour
warm water over the frozen area to
melt the ice. Wipe away the water
immediately to prevent it from
freezing.
 When the outside door handle is
frozen, unlock the doors using the
wireless remote control. If the out-
side door handles remain retracted
and do not move even if the doors
are unlocked using the wireless
remote control, pour warm water
over the frozen area to melt the ice
and wipe away the water immedi-
ately to prevent it from freezing. The
outside door handle may not retract
due to ice, however, the outside
door handle will return to the nor-
mal position after the ice melts.
 To ensure proper operation of the
climate control system fan, remove
any snow that has accumulated on
the air inlet vents in front of the
windshield.
 Check for and remove any excess
ice or snow that may have accumu-
lated on the exterior lights, vehicle’s
roof, chassis, around the tires or on
the brakes.
 Remove any snow or mud from the
bottom of your shoes before getting
in the vehicle.
■To protect windshield wipers
 P.198
Accelerate the vehicle slowly, keep a
safe distance between you and the
vehicle ahead, and drive at a reduced
speed suitable to road conditions.
Park the vehicle and shift the shift posi-
tion to P without setting the parking
brake. The parking brake may freeze
up, preventing it from being released. If
the vehicle is parked without setting
the parking brake, make sure to block
the wheels.
Failure to do so may be dangerous
because it may cause the vehicle to
move unexpectedly, possibly leading to
an accident.
NOTICE
■Repairing or replacing snow tires
Request repairs or re placement of snow
tires from any authorized Lexus retailer or Lexus authorized repairer, or any reli-able repairer.
This is because the removal and attach- ment of snow tires affects the operation
of the tire pressure warning valves and transmitters.

■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 period of time imme-
diately after the air conditioning system is started in automatic mode.
●When parking, the system automatically switches to fresh air intake mode to encourage better air circulation through-
out the vehicle, helping to reduce odors that occur when starting the vehicle.

mode is turned off.
■nanoe™ system
This vehicle incorporates a biocidal prod-
uct.
Ionised air generated by a device incorpo-
rated in the vehicle purifies the air in the
cabin by suppressing bacteria.
Active substance: Free radicals generated
in situ from ambient air or water
nanoe™ helps to provide purified air by
emitting electrically charged water parti-
cles through the front center vent on the
driver’s side
*.
●When the fan is turned on and nanoe™
on the option control screen is selected,
the nanoe™ system is activated.
●When the fan is operated in the following

●When nanoe™ is generated, a small
amount of ozone is emitted and may be
faintly smelled in some situations. How-
ever, this is approximately the same as the
amount that already exists in nature, such
as in forests, and it has no affect on the
human body.
●A slight noise may be heard during oper-
ation. This is not a malfunction.
*: According to temperature and humidity
conditions, fan speed and direction of the
air flow, the nanoe™ system may not
operate at full capacity.
