CAUTION
■Caution regarding the use of windshield wipers in AUTO mode
The windshield wipers may operate unexpectedly if the sensor is touched or the wind-
shield is subject to vibration in AUTO mode. Take care that your fingers or anything
else do not become caught in the windshield wipers.
■Caution regarding the use of washer fluid
When it is cold, do not use the washer fluid until the windshield becomes warm. The
fluid may freeze on the windshield and cause low visibility. This may lead to an accident,
resulting in death or serious injury.
NOTICE
■When the windshield is dry
Do not use the wipers, as they may damage the windshield.
■When there is no washer fluid spray from the nozzle
Damage to the washer fluid pump may be caused if the lever is pulled toward you and
held continually.
■When a nozzle becomes blocked
In this case, contact any authorized Lexus dealer or repairer, or another duly qualified
and equipped professional.
Do not try to clear it with a pin or other object. The nozzle will be damaged.

◆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 sur-
faces by controlling 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
◆Hill-start assist control
Prevents the vehicle from rolling backward when starting on an incline or slip-
pery slope
◆EPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to turn the
steering wheel
Driving assist systems
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.

3104-6. Driving tips
IS200t_EE(OM53D19E)
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.
XExcept vehicles with 18-inch tires

XVehicles with 18-inch tires
Tire chains cannot be mounted on the 18-inch tires.
Snow tires should be used instead.
Regulations regarding the use of tire chains vary depending on location and type
of road. Always check local regulations before installing chains.
■Tire chain installation
Observe the following precautions when installing and removing chains:
●Install and remove tire chains in a safe location.
●Install tire chains on the rear tires. Do not install tire chains on the front tires.
●Install tire chains on rear tires as tightly as possible. Retighten chains after driving 0.5
 1.0 km (1 /4  1 /2 mile).

Interior features
IS200t_EE(OM53D19E)
■Registering air conditioning settings to electronic keys (vehicles with driving position
memory)
●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.
●The doors that can recall the air conditioni ng setting when unlocked using the smart
entry & start system can be changed.* For details, contact any authorized Lexus dealer
or repairer, or another duly qualified and equipped professional.
*: The doors that can recall the driving position memory are changed at the same time.
■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 or “AUTO” is selected.
■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.
■Outside/recirculated air mode
●When driving on dusty roads such as tunnels or in heavy traffic, set the outside/recircu-
lated air mode button to the recirculated air mode. This is effective in preventing out-
side air from entering the vehicle interior. During cooling operation, setting the
recirculated air mode will also cool the vehicle interior effectively.
●Outside/recirculated air mode may automatically switch depending on the tempera-
ture setting or the inside temperature.
■Operation of the air conditioning system in Eco drive mode
In Eco drive mode, the air conditioning system is controlled as follows to prioritize fuel
efficiency:
●Engine speed and compressor operation controlled to restrict heating/cooling capac-
ity
●Fan speed restricted when automatic mode is selected
To improve air conditioning performance, perform the following operations:
●Adjust the fan speed
●Turn off Eco drive mode
■When the outside temperature falls to nearly 0 °C (32 °F)
The dehumidification function may not operate even when is pressed or “A/C” is
selected.

4086-1. Using the air conditioning system
IS200t_EE(OM53D19E)
■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 accu-
mulate in the air conditioning system. This may then cause odor to be emitted from the
vents.
●To reduce potential odors from occurring:
• It is recommended that the air conditioning system be set to outside air mode priorto turning the vehicle off.
• The start timing of the blower may be delayed for a short period of time immediately
after the air conditioning system is started in automatic mode.
■Air conditioning filter
→ P. 4 6 4
■Customization
Settings (e.g. A/C Auto switch operation) can be changed.
(Customizable features →P. 5 8 3 )
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.
■To prevent burns
●Do not touch the rear view mirror surfaces when the outside rear view mirror defog-
gers are on.
●Do not touch the glass at lower part of the windshield or to the side of the front pillars
when the windshield wiper de-icer is on.
NOTICE
■To prevent battery discharge
Do not leave the air conditioning system on longer than necessary when the engine is
off.
●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.

■The interior lights and personal lights can be operated when
The interior lights and personal lights can be used regardless of the engine switch mode.
However, when the engine switch is turned off, they can be used only when the battery
protection function is not operating.
■Battery protection function
To prevent the battery from being discharged, approximately 20 minutes after the
engine switch is turned off, the power supplied to the interior lights, personal lights, and
other lights will be cut off automatically. (If the interior lights, etc. are left on when the
engine switch is turned off, they will be turned off automatically.)
To turn the interior lights, etc. back on, tu rn the engine switch to ACCESSORY or IGNI-
TION ON mode or operate the interior light switch until the interior lights turn on.
If any of the lights are illuminated automatically due to the illuminated entry system, the
battery protection function will be canceled.
■Illuminated entry system
The lights automatically turn on/off according to engine switch mode, the presence of the
electronic key, whether the doors are locked/unlocked, and whether the doors are
opened/closed.
■Customization
Setting (e.g. the time elapsed before lights turn off) can be changed.
(Customizable features: →P. 5 76 )
NOTICE
To prevent battery discharge, do not leave the lights on longer than necessary when the
engine is off.
