CAUTION
■To avoid inadvertent cruise control activation
Switch the cruise control off using the “ON/OFF” button when not in use.
■Situations unsuitable for dynamic radar cruise control
Do not use dynamic radar cruise control in any of the following situations.
Doing so may result in inappropriate speed control and could cause an accident
resulting in death or serious injury.
●In heavy traffic
●On roads with sharp bends
●On winding roads
●On slippery roads, such as those covered with rain, ice or snow
●On steep downhills, or where there are sudden changes between sharp up and
down gradients
Vehicle speed may exceed the set speed when driving down a steep hill.
●At entrances to expressways
●When weather conditions are bad enough that they may prevent the sensors
from functioning correctly (fog, snow, sandstorm, heavy rain, etc.)
●When an approach warning buzzer is heard often
●During emergency towing

4-5. Using the driving support systems
Pulling the lever toward you can-
cels the cruise control.
The setting is also canceled when the
brake pedal is depressed while driv-
ing.
(When the vehicle has been stopped
by system control, applying the brakes
does not cancel the setting.)
Pushing the lever up resumes the
cruise control and returns vehicle
speed to the set speed.
However, when a vehicle ahead is not
detected in vehicle-to-vehicle dis-
tance control mode, cruise control
does not resume when the actual vehi-
cle speed is approximately 25 mph
(40 km/h) or less. Also, when the
vehicle is in constant speed control
mode and the actual vehicle speed is
approximately 25 mph (40 km/h) or
less, cruise control does not resume as
the set speed is cleared.

■To avoid inadvertent dynamic radar cruise control with full-speed range activa-
tion
Switch the cruise control off using the “ON/OFF” button when not in use.
■Situations unsuitable for dynamic radar cruise control with full-speed range

etc.
●When there are visible lines on the pavement from road repairs, or if the remains
of old lane markers are still visible on the road

●When driving in a lane other than the driving or passing lanes on a freeway or
highway
●When driving on a road with lane closures due to maintenance, or when driving
in a temporary lane

■Intuitive parking assist display
When an obstacle is detected while the rear view monitor system, is in use, the warn-
ing indicator will appear in the top right of the screen even if the display setting has
been set to off.
■Sensor detection information
●The sensor’s detection areas are limited to the areas around the vehicle’s bumpers.
●Certain vehicle conditions and the surrounding environment may affect the ability
of the sensor to correctly detect obstacles. Particular instances where this may
occur are listed below.
• There is dirt, snow or ice on the sensor. (Wiping the sensors will resolve thisproblem.)
• The sensor is frozen. (Thawing the area will resolve this problem.) In especially cold weather, if a sensor is frozen the screen may show an abnor-
mal display, or obstacles may not be detected.
• The sensor is covered in any way.
• The vehicle is leaning considerably to one side.
• On an extremely bumpy road, on an incline, on gravel, or on grass.
• The vicinity of the vehicle is noisy due to vehicle horns, motorcycle engines, air brakes of large vehicles, or other loud noises producing ultrasonic waves.
• There is another vehicle equipped with parking assist sensors in the vicinity.
• The sensor is coated with a sheet of spray or heavy rain.
• The vehicle is equipped with a fender pole or wireless antenna.
• Towing eyelets are installed.
• The bumper or sensor receives a strong impact.
• The vehicle is approaching a tall or curved curb.
• In harsh sunlight or intense cold weather.
• The area directly under the bumpers is not detected.
• If obstacles draw too close to the sensor.
• A non-genuine Lexus suspension (lowered suspension etc.) is installed.
• People may not be detected if they are wearing certain types of clothing.
In addition to the examples above, there are instances in which, because of their
shape, signs and other objects may be judged by the sensor to be closer than they
are.

■When using the microphone
●It is unnecessary to speak directly into the microphone when giving a command.
●Wait for the confirmation beep before speaking a command.
●Voice commands may not be recognized if:
• Spoken too quickly.
• Spoken at a low or high volume.
• The roof or windows are open.
• Passengers are talking while voice commands are spoken.
• The air conditioning speed is set high.
• The air conditioning vents are turned towards the microphone.
●In the following conditions, the system may not recognize the command properly
and using voice commands may not be possible:
• The command is incorrect or unclear. Note that certain words, accents orspeech patterns may be difficult for the system to recognize.
• There is excessive background noise, such as wind noise.
■When searching for a track
●A USB memory or iPod must be connected to enable track searching and play-
back. ( →P. 5 0 1 , 5 1 1 )
●When a USB memory or iPod is connected, recognition data is created so tracks
can be searched using voice commands.
●Recognition data is updated under the following conditions:
• When the USB memory or iPod data has changed.
• When the voice recognition language is changed. ( →P. 3 6 1 )
●While the recognition data is being created or being updated, a track search can-
not be performed using a voice command.
●While “Play Music” is displayed in the “Shortcut Menu” screen, say “Play Music” to
display the music screen from which searching for a track using a voice command
can be performed.
●When “Play Music” is dimmed in the “Shortcut Menu” screen, it is not possible to
search for a track using a voice command. In this situation, reduce the amount of
music data in the USB memory or iPod and update the recognition data to enable
searching by voice command.
