Detection range of the sensors
Approximately 100 cm (3.3 ft.)
Approximately 150 cm (4.9 ft.)
Approximately 50 cm (1.6 ft.)
The diagram shows the detection
range of the sensors. Note that the
sensors cannot detect obstacles
that are extremely close to the
vehicle.
The range of the sensors may
change depending on the shape of
the object etc.
■The Lexus parking assist-sensor can be operated when
●Front corner sensors:
• The “ENGINE START STOP” switch is in IGNITION ON mode.
• The shift lever is in a position other than P.
• The vehicle speed is less than about 10 km/h (6 mph).
●Front center sensors:
• The “ENGINE START STOP” switch is in IGNITION ON mode.
• The shift lever is in a position other than P or R.
• The vehicle speed is less than about 10 km/h (6 mph).
●Rear corner and center sensors:

■Sensor detection information
●Certain vehicle conditions and the surrounding environment may affect the
ability of a sensor to correctly detect an obstacle. Particular instances where this
may occur are listed below.
• There is dirt, snow or ice on a sensor.
• A sensor is frozen.
• A 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.
• A sensor is coated with a sheet of spray or heavy rain.
• The vehicle is equipped with a fender pole or radio antenna.
• Towing eyelets are installed.
• A bumper or sensor receives a strong impact.
• The vehicle is approaching a tall or right-angled curb.
• In harsh sunlight or intense cold weather.
• A non-genuine Lexus suspension (lowered suspension, etc.) is installed.
In addition to the examples above, there are instances in which, because of their
shapes, signs and other objects may be judged by a sensor to be closer than they
are.
●The shape of the obstacle may prevent a sensor from detecting it. Pay particular
attention to the following obstacles:
• Wires, fences, ropes, etc.
• Cotton, snow and other materials that absorb sound waves
• Sharply-angled objects
• Low obstacles
• Tall obstacles with upper sections projecting outwards in the direction of your
vehicle

Failing to do so may result in the vehicle being unable to be driven safely and possi-
bly cause an accident.
●Do not use the sensor at speeds in excess of 10 km/h (6 mph).
●Do not attach any accessories within the sensor range.
NOTICE
■Notes when washing the vehicle
Do not apply intensive bursts of water or steam to the sensor area.
Doing so may result in the sensor malfunctioning.
■Conditions possibly indicating system malfunctions
If any of the following occurs, the system may be malfunctioning due to a sensor fail-
ure etc. Have the vehicle inspected by any authorized Lexus dealer or repairer, or
another duly qualified and equipped professional.
●The buzzer does not sound when the Lexus parking assist-sensor mode is set.
●The sensor operation display flashes and the buzzer sounds even when no obsta-
cle is detected.
●An area of the sensors is hit or subjected to a strong impact.
●Either bumper is hit.

Hill-start assist control
■Hill-start assist control can be operated when
●The shift lever is in a position other than P.
●The parking brake is not applied.
●The accelerator pedal is not depressed.
■Hill-start assist control
●While hill-start assist control is operating, the brakes remain automatically
applied after the driver releases the brake pedal. The stop lights and the high
mounted stoplight turn on.
●Hill-start assist control operates for about 2 seconds after the brake pedal is
released.
●If the slip indicator does not flash and the buzzer does not sound when the brake
pedal is further depressed, slightly reduce the pressure on the brake pedal (do
not allow the vehicle to roll backward) and then firmly depress it again. If the sys-
tem still does not operate, check if the operating conditions explained above
have been met.
Hill-start assist control helps to prevent the vehicle from rolling backwards
when starting on an incline or slippery slope.
To engage hill-start assist con-
trol, further depress the brake
pedal when the vehicle is
stopped completely.
A buzzer will sound once to
indicate the system is activated.
The slip indicator will also start
flashing.

■Hill-start assist control buzzer
●When hill-start assist control is activated, the buzzer will sound once.
●In the following situations, hill-start assist control will be canceled and the
buzzer will sound twice.
• No attempt is made to drive the vehicle within approximately 2 seconds of
releasing the brake pedal.
• The shift lever is moved to P.
• The parking brake is applied.
• The brake pedal is depressed again.
• The brake pedal has been depressed for more than approximately 3 minutes.
●If a buzzer other than the hill-start assist control buzzer is sounding, the hill-start
assist control buzzer may not sound when the system is activated or canceled.
■If the slip indicator comes on
It may indicate a malfunction in the system. Contact any authorized Lexus dealer or
repairer, or another duly qualified and equipped professional.
CAUTION
■Hill-start assist control
●Do not overly rely on hill-start assist control. Hill-start assist control may not oper-
ate effectively on extremely steep inclines or roads covered in ice.
●Unlike the parking brake, hill-start assist control is not intended to hold the vehi-
cle stationary for an extended period of time. Do not attempt to use hill-start
assist control to hold the vehicle on an incline for an extended period of time, as
doing so may lead to an accident.
