When bringing an electronic key onto an aircraft, make sure you do not press any but-
tons on the electronic key while inside the airc
raft cabin. If you are carrying an electronic
key in your bag etc., ensure that the buttons are not likely to be pressed accidentally.
Pressing a button may cause the electronic key to emit radio waves that could interfere
with the operation of the aircraft.
■Electronic key battery depletion
●The standard battery life is 1 to 2 years.
●If the battery becomes low, an alarm will sound in the cabin when the engine is stopped.

even if the electronic key is not used. The following symptoms indicate that the elec-
tronic key battery may be depleted. Replace the battery when necessary. ( →P. 491)
• The smart access system with push-button start or the wireless remote control does
not operate.
• The detection area becomes smaller.
• The LED indicator on the key surface does not turn on.

GX460_OM_OM60Q09U_(U)4-5. Using the driving support systems
■Dynamic radar cruise control can be set when
●The shift lever is in the D or range 4 or higher of S has been selected.
●Vehicle speed is above approximately 30 mph (50 km/h).
■Switching modes
The mode cannot be switched to constant sp
eed control mode if vehicle-to-vehicle dis-
tance control mode has been used. The mode also cannot be switched from constant
speed control to vehicle-to-vehicle distance control mode. Turn the system off by press-
ing the “ON-OFF” button, and turn it on again.
■Accelerating after setting the vehicle speed
The vehicle can accelerate normally. After acceleration, the set speed resumes. How-
ever, during vehicle-to-vehicle distance control mode, the vehicle speed may decrease
below the set speed in order to maintain the distance to the vehicle ahead.
■Automatic cancelation of vehicle-to-vehicle distance control
Vehicle-to-vehicle distance control driving is automatically canceled in the following situ-
ations:
●Actual vehicle speed falls below approximately 25 mph (40 km/h).
●VSC is activated.
●The sensor cannot operate correctly because it is covered in some way.
●The windshield wipers are operating at high speed (when the wiper switch is set to the
“AUTO” mode or the high speed wiper operation position).
●When second start mode is set.
●Bad weather causes the detection function to become extremely unstable.
●Multi-terrain mode is selected other than OFF.
●The center differential lock/unlock is not completed within 5 seconds while the
dynamic radar cruise control system is on.
If vehicle-to-vehicle distance control drivin g is automatically canceled for any other rea-
son, there may be a malfunction in th e system. Contact your Lexus dealer.
■Automatic cancelation of constant speed control
The cruise control will stop maintaining the vehicle speed in the following situations:
●Actual vehicle speed is more than approxim ately 10 mph (16 km/h) below the set vehi-
cle speed.
At this time, the memorized set speed is not retained.
●Actual vehicle speed falls below approximately 25 mph (40 km/h).
●VSC is activated.
●The center differential lock/unlock is not completed within 5 seconds while the
dynamic radar cruise control system is on.

Interior features
■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 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 access system with push-button start is used to unlock a passenger door.
Settings for the electronic key and th e corresponding door can be changed.
Contact your Lexus dealer.
■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 the “AUTO” button is pressed.
■When the outside temperature exceeds 75 °F (24 °C) and the air conditioning system
is on
●In order to reduce the air co nditioning power consumption, the air conditioning system
may switch to recirculated air mode automatically.
This may also reduce fuel consumption.
●Recirculated air mode is selected as a defaul t mode when the engine switch is turned to
IGNITION ON mode.
●It is possible to switch to outside air mode at any time by pressing or
.
■Fogging up of the windows
●The windows will easily fog up when the humidi ty in the vehicle is high. Touching “A/C”
on will dehumidify the air from the outl ets 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 enteri ng the vehicle interior. During cooling operation, setting the
recirculated air mode will also cool the vehicle interior effectively.
●Outside/recirculated air mode may automa tically switch depending on the tempera-
ture setting or the inside temperature.
