pedal while starting the engine under any circumstances.
Doing so may cause an accident resulting in death or serious injury.
■Caution while driving

the engine off while driving will not cause lo ss of steering or braking control, but the
power assist to these systems will be lost. Th is will make it more difficult to steer and
brake, so you should pull over and stop the vehicle as soon as it is safe to do so.

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.

■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.

●Working from top to bottom, liberally
apply water to the vehicle body, wheel
wells and underside of the vehicle to remove any dirt and dust.
●Wash the vehicle body using a sponge or soft cloth, such as a chamois.
●For hard-to-remove marks, use car wash soap and rinse thoroughly with
water.
●Wipe away any water.
●Wax the vehicle when the waterproof coating deteriorates.
If water does not bead on a clean surface, apply wax when the vehicle body is cool.
■Self-restoring coat
The vehicle body has a self-restoring coating that is resistant to small surface scratches
caused in a car wash etc.
●The coating lasts for 5 to 8 years from when the vehicle is delivered from the plant.
●The restoration time differs depending on the depth of the scratch and outside temper-
ature.
The restoration time may become shorter when the coating is warmed by applying
warm water.
●Deep scratches caused by keys, coins, etc. cannot be restored.
●Do not use wax that contain abrasives.
■Automatic car washes
●Fold the mirrors before washing the vehicle. Start washing from the front of the vehicle.
Make sure to extend the mirrors before driving.
●Brushes used in automatic car washes may scratch the vehicle surface and harm your
vehicle’s paint.
■High pressure car washes
●Do not allow the nozzles of the car wash to come within close proximity of the windows.
●Before using the car wash, check that the fuel filler door on your vehicle is closed prop-
erly.
■When using a car wash (vehicles with entry function)
If the door handle becomes wet while the electronic key is within the effective range, the
door may lock and unlock repeatedly. In that case, follow the following correction proce-
dures to wash the vehicle:
●Place the key in a position 2 m (6 ft.) or more separate from the vehicle while the vehi-
cle is being washed. (Take care to ensure that the key is not stolen.)
●Set the electronic key to battery-saving mode to disable the smart entry & start system.

start with the engine switch turned off. Ho wever, the engine will operate normally from
the second attempt.
●The engine switch mode is recorded by the vehicle. If the battery is disconnected and
reconnected, the vehicle will return the engine switch mode to the status it was in
before the battery was disconnected. Make sure to turn off the engine before discon-
necting the battery. Take extra care when connecting the battery if the engine switch
mode prior to the battery being disconnected is unknown.
