Driving assist systems
◆ABS (Anti-lock Brake System)
Helps to prevent wheel lock when the brakes are applied suddenly, or if
the brakes are applied while driving on a slippery road surface
◆Brake assist
Generates an increased level of braking force after the brake pedal is
depressed when the system detects a panic stop situation
◆VSC (Vehicle Stability Control)
Helps the driver to control skidding when swerving suddenly or turning
on slippery road surfaces
◆VSC+ (Vehicle Stability Control+)
Provides cooperative control of the ABS, TRC, VSC and EPS.
Helps to maintain directional stability when swerving on slippery road
surfaces by controlling steering performance.
◆TRC (Traction Control)
Helps to maintain drive power and prevent the drive wheels from spin-
ning when starting the vehicle or accelerating on slippery roads
◆Hill-start assist control
→ P. 328
To help enhance driving safety and performance, the following systems
operate automatically in response to various driving situations. Be
aware, however, that these system s are supplementary and should not
be relied upon too heavily when operating the vehicle.

●Pre-crash alert braking:
• The system determines that the driver is not facing forward, or that the driver’seyes are closed.
• Vehicle speed is greater than about 40 km/h (25 mph).
• The speed at which your vehicle is approaching the vehicle running ahead of you is greater than about 40 km/h (25 mph).
• The steering is not being turned.
■Conditions that may trigger the system even if there is no danger of a collision
●When there is an object by the roadside at the entrance to a curve
●When passing an oncoming vehicle on a curve
●When driving over a narrow iron bridge
●When there is a metal object on the road surface
●When driving on an uneven road surface
●When passing an oncoming vehicle on a left-turn (left-hand drive vehicles) or right-
turn (right-hand drive vehicles)
●When your vehicle rapidly closes on the vehicle in front
●When a grade separation/interchange, sign, billboard, or other structure appears
to be directly in the vehicle’s line of travel
●When climbing a steep hill causes an overhead billboard or other metallic structure
to appear directly in the vehicle’s line of travel
When the system is activated in the situations described above, there is also a possi-
bility that the seat belts will retract quickly and the brakes will be applied with a force
greater than normal. When the seat belt is locked in the retracted position, stop the
vehicle in a safe place, release the seat belt and refasten it.
■Obstacles not detected
The sensor cannot detect plastic obstacles such as traffic cones. There may also be
occasions when the sensor cannot detect pedestrians, animals, bicycles, motorcy-
cles, trees, or snowdrifts.

CAUTION
■Limitations of the pre-crash safety system
Do not overly rely on the pre-crash safety system. Always drive safely, taking care
to observe your surroundings and checking for any obstacles or other road haz-
ards.
Failure to do so may cause an accident resulting in death or serious injury.
■Handling the radar sensor
Observe the following to ensure the pre-crash safety system can function effec-
tively. Otherwise, the system may not function correctly and could result in an acci-
dent.
●Keep the sensor and grille cover clean at all times.
Clean the sensor and grille cover with a soft cloth so you do not mark or damage
them.
●Do not subject the sensor or surrounding area to a strong impact.
If the sensor moves even slightly off position, the system may become inaccurate
or malfunction. If the sensor or surrounding area is subject to a strong impact,
always have the area inspected and adjusted by any authorized Lexus dealer or
repairer, or another duly qualified and equipped professional.
●Do not disassemble the sensor.
●Do not attach accessories or stickers to the sensor, grille cover or surrounding
area.
●Do not modify or paint the sensor and grille cover.
●Do not replace them with non-genuine parts.
■Determining the direction the driver is facing and whether the driver’s eyes are
open or closed
The direction the driver is facing and whether the driver’s eyes are open or closed
may not be determined correctly if the following conditions exist:
●There is an object between the driver monitor sensor and the driver’s face, such
as when the sensor is blocked.
●A part of the driver’s face is covered.
●The sensor or the driver’s face is exposed to intense light such as sunlight.
●The driving posture is improper.

Driving
GS350_250_OM_OM30E16E_(EE)
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.
●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 wind-
shield.
●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.
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 move the shift lever to P without setting the parking
brake. The parking brake may freeze up, preventing it from being
released. If necessary, block the wheels to prevent inadvertent sliding or
creeping.

GS350_250_OM_OM30E16E_(EE)
■Registering air conditioning settings to electronic keys
●Unlocking the vehicle using an electronic key and turning the engine switch to
IGNITION ON mode will recall that key’s registered air conditioning settings.
●When the engine switch is turned off, the current air conditioning settings will auto-
matically be registered to the electronic key that was used to unlock the vehicle.
The system may not operate correctly if more than one electronic key is in the vicinity
or if the smart entry & start system is used to unlock a passenger door.
Settings for the electronic key and the corresponding door can be changed. Contact
any authorized Lexus dealer or repairer, or another duly qualified and equipped pro-
fessional.
■Using automatic mode
●Fan speed is adjusted automatically according to the temperature setting and the
ambient conditions.
Therefore, the fan may stop for a while until warm or cool air is ready to flow imme-
diately after is pressed.
●Cool air may blow around the upper body even when the heater is on due to sun-
light.
■Humidity sensor
A sensor, which detects humidity inside the
vehicle and the temperature of the wind-
shield, is provided to detect fog on the front
windscreen. Due to the sensor, when auto-
matic mode is set the air conditioning may
make the following controls:
●Changing the amount of air flow
●Changing the amount of air introduced from
outside when in outside air mode with the air
vents in the position
●Changing the settings of the air vents to
when the is set

GS350_250_OM_OM30E16E_(EE)
CAUTION
■To prevent the windshield from fogging up
Do not use
during cool air operation in extremely humid weather. The differ-
ence between the temperature of the outside air and that of the windshield can
cause the outer surface of the windshield to fog up, blocking your vision.
■nanoe  generator
Do not disassemble or repair the generator because it contains high voltage parts.
Contact any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional if the generator needs repair.
NOTICE
■To prevent battery discharge
Do not leave the air conditioning system on longer than necessary when the
engine is stopped.
■Humidity sensor
Follow these points to avoid damaging the sensor:
●Do not disassemble the sensor
●Do not spray the glass cleaner on the sensor or subject it to strong impacts
●Do not stick anything on the sensor
■To prevent damage to the nanoe 
Do not insert anything into the driver’s side vent, attach anything to it, or use sprays
around the driver’s side vent. These things may cause the generator not to work
properly.
