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 main-
tain directional stability when swerving on slippery road surfaces by control-
ling steering performance.
◆TRC (Traction Control)
Helps to maintain drive power and prevent the drive wheels from spinning
when starting the vehicle or accelerating on slippery roads
To help enhance driving safety and performance, the following systems oper-
ate automatically in response to various driving situations. Be aware, however,
that these systems are supplementary and should not be relied upon too
heavily when operating the vehicle.

Driving
GS350_200t_GS F_OM_OM30E87E_(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 imme-
diately 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 windshield.
●Check for and remove any excess ice or snow that may have accumulated 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 leve r 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.
XVehicles with front and rear tires of the same size
Use the correct tire chain size when mounting the tire chains.
Chain size is regulated for each tire size.
Side chain
(3 mm [0.12 in.] in diameter)
Cross chain
(4 mm [0.16 in.] in diameter)
XVehicles with front and rear tires of differing sizes
Tire chains cannot be mounted.
Snow tires should be used instead.

■Adjusting the position of and op ening and closing the air outlets
Direct air flow to the left or right, up or down.
Turn the knob to open or close the vent.
■Registering air conditioning settings to electronic keys
●Unlocking the vehicle using an electronic ke y and turning the engine switch to IGNI-
TION ON mode will recall that key’s registered air conditioning settings.
●When the engine switch is turned off, the current air conditioning settings will automat-
ically 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 profes-
sional.
■Using automatic mode
Fan speed is adjusted automatically according to the temperature setting and the ambi-
ent conditions.
Therefore, the fan may stop for a while until wa rm or cool air is ready to flow immediately
after is pressed.
Cool air may blow around the upper body even when the heater is on due to sunlight.
■Fogging up of the windows
●The windows will easily fog up when the humidity in the vehicle is high. Turning “A/C”
on will dehumidify the air from the outlets and defog the windshield effectively.
●If you turn “A/C” off, the windows may fog up more easily.
●The windows may fog up if the recirculated air mode is used.

■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.
■To prevent burns
Do not touch the rear view mirror surfaces when the outside rear view mirror defog-
gers are on.
■nanoe generator (if equipped)
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.
■To prevent damage to the nanoe (if equipped)
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 prop-
erly.
●Do not place anything on the instrument
panel which may cover the air outlets. Other-
wise, air flow may be obstructed, preventing
the windshield defoggers from defogging.
