■Before using dynamic radar cruise control
Do not overly rely on vehicle-to-vehicle distance control.
Be aware of the set speed. If automatic deceleration/acceleration is not appropriate,
adjust the vehicle speed, as well as the distance between your vehicle and vehicles
ahead by applying the brakes etc.

■When the sensor may not be correctly detecting the vehicle ahead
Apply the brakes as necessary when any of the following types of vehicles are in front of
you.
As the sensor may not be able to correctly detect these types of vehicles, the approach
warning (→P. 213) will not be activated, and a fatal or serious accident may result.
●Vehicles that cut in suddenly
●Vehicles traveling at low speeds
●Vehicles that are not moving
●Vehicles with small rear ends (trailers with no load on board etc.)
●Motorcycles traveling in the same lane
■Conditions under which the vehicle-to-vehic le distance control may not function cor-
rectly
Apply the brakes as necessary in the following conditions as the radar sensor may not
be able to correctly detect vehicles ahead, and a fatal or serious accident may result:
●When water or snow thrown up by the surrounding vehicles hinders the functioning
of the sensor
●When your vehicle is pointing upwards (caused by a heavy load in the luggage com-
partment etc.)
●When the road curves or when the lanes are narrow
●When steering wheel operation or your position in the lane is unstable
●When the vehicle ahead of you decelerates suddenly
■Handling the radar sensor
Observe the following to ensure the cruise control system can function effectively.
Otherwise, the system may not function correctly and could result in an accident.
●Keep the sensor and grille cover clean at all times.
Clean the sensor and grille cover with a soft cloth so you do not mark or damage
them.
●Do not subject the sensor or surrounding area to a strong impact.
If the sensor moves even slightly off positi on, the system may malfunction. If the sen-
sor or surrounding area is subject to a strong impact, always have the area inspected
and adjusted by any authorized Lexus dealer or repairer, or another duly qualified
and equipped professional.
●Do not disassemble the sensor.
●Do not attach accessories or stickers to the sensor, grille cover or surrounding area.
●Do not modify or paint the sensor and grille cover.
●Do not replace them with non-genuine parts.

■Lexus parking assist-sensor display
When an obstacle is detected while the rear view monitor system or Lexus parking assist
monitor is in use, the warning indicator will appear in the upper corner 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 bumper.
●Certain vehicle conditions and the surround ing 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 the sensor. (Wiping the sensors will resolve this prob- lem.)
• 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 abnormal
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 (low ered 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 a sensor to be closer than they are.
●The shape of the obstacle may prevent a sensor from detecting it. Pay particular atten-
tion 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 vehi-
cle

Driving assist systems
◆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
◆TRC (Traction Control)
Helps to maintain drive power and pr event the drive wheels from spinning
when starting the vehicle or accelerating on slippery roads
◆EPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to turn the
steering wheel
◆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.
◆Hill-start assist control
→ P. 2 4 2
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.

◆PCS (Pre-Crash Safety system) (if equipped)
→P. 2 4 4
◆Emergency brake signal
When the brakes are applied suddenly, the stop lights automatically flash to
alert the vehicle behind.
The slip indicator light will flash while
the VSC/TRC/ABS systems are oper-
ating.
If the vehicle gets stuck in mud, dirt or snow, the TRC system may reduce power
from the hybrid system to the wheels. Pressing to turn the system off may
make it easier for you to rock the vehicle in order to free it.
To turn the TRC system off, quickly
press and release .
The “TRC OFF” indicator light will come
on.
Press again to turn the system
back on.

Hill-start assist control
To engage hill-start assist control, fur-
ther 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 operating conditions
●The system operates in the following situations:
• The shift position is in a position other than P.
• The parking brake is not applied.
• The accelerator pedal is not depressed.
●Hill-start assist control cannot be operated wh ile the slip indicator light is illuminated.
■Hill-start assist control
●While hill-start assist control is operating, the brakes rema in 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 depr ess it again. If the system still does not
operate, check if the operating conditions explained above have been met.
■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 wi thin approximately 2 seconds of releasing
the brake pedal.
• Push the P position switch.
• The parking brake is applied.
• The brake pedal is depressed again.
• The brake pedal has been depressed for more than approximately 3 minutes.
Assists with starting off and temporarily maintains braking power even if the
foot is removed from the brake pedal when starting off on an incline or a slip-
pery slope.

PCS (Pre-Crash Safety system)∗
◆Pre-crash seat belts (front seat belts only)
If the pre-crash sensor detects that a collision is unavoidable, the pre-crash
safety system will retract the seat belt before the collision occurs.
The same will happen if the driver makes an emergency braking or loses con-
trol of the vehicle. ( →P. 3 9 )
However, when the VSC system is disabled, the system will not operate in the
event of skidding.
◆Pre-crash brake assist
When there is a high possibility of a frontal collision, the system applies
greater braking force in relation to how strongly the brake pedal is depressed.
◆Pre-crash braking
When there is a high possibility of a frontal collision, the system warns the
driver using a warning light, warning di splay and buzzer. If the system deter-
mines that a collision is unavoidable, the brakes are automatically applied to
reduce the collision speed. Pre-crash braking can be disabled using the pre-
crash braking off switch.
Pre-crash braking disabled
Pre-crash braking enabled
The “PCS” warning light will turn on
when pre-crash braking is disabled.
∗: If equipped
When the radar sensor detects possibilit y of a frontal collision, the pre-crash
safety system such as the brakes and seat belts are automatically engaged to
lessen impact as well as vehicle damage.

■Conditions that may trigger the system even if there is no possibility of a collision
●When there is an object by the roadside at the entrance to a curve
●When passing an oncoming vehicle on a curve
●When driving over a narrow iron bridge
●When there is a metal object on the road surface
●When driving on an uneven road surface (nose up, nose down)
●When passing an oncoming vehicle on a left-turn (left-hand drive vehicles) or right-turn
(right-hand drive vehicles)
●When your vehicle rapidly closes on the vehicle in front
●When a grade separation/interchange, sign, billboard, or other structure appears to be
directly in the vehicle’s line of travel
●When the steep angle of the road causes a metal object located beneath the road sur-
face to be seen ahead of the vehicle
●When an extreme change in vehicle height occurs
●When the axis of the radar is out of adjustment
●When passing through certain toll gates
●When passing through an overpass
●When passing through a tunnel
When the system is activated in the situations described above, there is also a possibility
that the seat belts will retrac t quickly and the brakes will be applied with a force greater
than normal. When the seat belt is locked in the retracted position, stop the vehicle in a
safe place, release the seat belt and refasten it.
■Obstacles not detected
The sensor cannot detect plastic obstacles su ch as traffic cones. There may also be occa-
sions when the sensor cannot detect pedestri ans, animals, bicycles, motorcycles, trees,
or snowdrifts.
■Situations in which the pre-crash safe ty system does not function properly
The system may not function effectively in situations such as the following:
●On roads with sharp bends or uneven surfaces
●If a vehicle suddenly moves in front of vehicle, such as at an intersection
●If a vehicle suddenly cuts in front of vehicle, such as when overtaking
●In inclement weather such as heavy rain, fog, snow or sand storms
●When your vehicle is skidding with the VSC system off
●When an extreme change in vehicle height occurs
●When the axis of the radar is out of adjustment
■Automatic cancelation of the pre-crash safety system
When a malfunction occurs due to sensor contamination, etc. that results in the sensors
being unable to detect obstacles, the pre-crash safety system will be automatically dis-
abled. In this case, the system will not activa te even if there is a collision possibility.
■When there is a malfunction in the system, or if the system is temporarily unusable
Warning lights and/or warning messages will turn on or flash. (→P. 5 1 5 , 5 2 1 )
