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 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 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

Rear view monitor system camera
The camera uses a special lens. The
distance of the image that appears on
the screen differs from the actual dis-
tance.
In the following cases, it may be diffi-
cult to see the images on the screen,
even when the system is functioning
correctly.
• In the dark (e.g. at night).
• If the temperature near the lens is
extremely high or low.
• If water droplets get on the camera,
or when humidity is high (e.g. when
it rains).
• If foreign matter (e.g. snow or mud)
get on the camera lens.
• If the sun or headlights are shining
directly into the camera lens.
• When the camera has scratches or
dirt on it.
• A bright object such as a white wall
is reflected in the mirror surface
over the monitor.
• When the camera is used under flu-
orescent light, sodium lights, or

Smear effect
Flicker effect
When the camera is used under fluorescent lights, sodium lights, mercury
lights, etc., the lights and the illuminated areas may appear to flicker.
If a bright light (e.g. sunlight reflected off
the vehicle body) is picked up by the
camera, a smear effect
* peculiar to the
camera may occur.
*: Smear effect — A phenomenon that
occurs when a bright light (for exam-
ple, sunlight reflected off the vehicle
body) is picked up by the camera;
when transmitted by the camera, the
light source appears to have a vertical
streak above and below it.

CAUTION
Conditions which may affect the rear view monitor system
If the back of the vehicle has been hit, the camera’s position and mounting
angle may have been changed. Have the vehicle inspected by any autho-
rized Lexus dealer or repairer, or another duly qualified and equipped pro-
fessional.
Rapid temperature changes, such as when hot water is poured on the vehi-
cle in cold weather, may cause the system to function abnormally.
If the camera lens is dirty, it cannot transmit a clear image. Rinse with
water and wipe with a soft cloth. If the camera lens is extremely dirty,
wash with a mild cleanser and rinse.
The displayed image may be darker and moving images may be slightly
distorted when the system is cold.
When washing the vehicle, do not apply intensive bursts of water to the
camera or camera area. Doing so may result in the camera malfunctioning.
Do not allow organic solvent, car wax, window cleaner or glass coat to
adhere to the camera. If this happens, wipe it off as soon as possible.
As the camera has a water proof construction, do not detach, disassemble
or modify it. This may cause incorrect operation.
Do not hit the camera or subject it to strong impacts as this may cause its
position and mounting angle to change.
Do not scrub the camera lens roughly or clean it with a hard brush or abra-
sive cleaner. Doing so may damage the lens and adversely affect the
image.

When the VSC/TRC systems are operating
If the vehicle is in danger of
slipping or if any of the drive
wheels spins, the slip indicator
light flashes to indicate that the
VSC/TRC systems are operat-
ing.
Sounds and vibrations caused by the ABS, brake assist, VSC and TRC
A sound may be heard from the engine compartment when the hybrid
system is started, just after the vehicle begins to move, if the brake pedal
is depressed forcefully or repeatedly, or 1-2 minutes after the hybrid sys-
tem is stopped. This sound does not indicate that a malfunction has
occurred in any of these systems.
Any of the following conditions may occur when the above systems are
operating. None of these indicates that a malfunction has occurred.
• Vibrations may be felt through the vehicle body and steering.
• A motor sound may be heard after the vehicle comes to a stop.
• The brake pedal may pulsate slightly after the ABS is activated.
• The brake pedal may move down slightly after the ABS is activated.
EPS operation sound
When the steering wheel is operated, a motor sound (whirring sound) may
be heard. This does not indicate a malfunction.
Reduced effectiveness of the EPS system
The effectiveness of the EPS system is reduced to prevent the system from
overheating when there is frequent steering input over an extended period of
time. The steering wheel may feel heavy as a result. Should this occur,
refrain from excessive steering input or stop the vehicle and turn the hybrid
system off. The EPS system should return to normal within 10 minutes.

CAUTION
TRC may not operate effectively when
Directional control and power may not be achievable while driving on slip-
pery road surfaces, even if the TRC system is operating.
Do not drive the vehicle in conditions where stability and power may be
lost.
When the VSC is activated
The slip indicator light flashes. Always drive carefully. Reckless driving
may cause an accident. Exercise particular care when the indicator light
flashes.
Replacing tires
Make sure that all tires are of the specified size and of the same brand, tread
pattern and total load capacity. In addition, make sure that the tires are
inflated to the recommended tire inflation pressure level.
The ABS and VSC systems will not function correctly if different tires are
installed on the vehicle.
Contact any authorized Lexus dealer or repairer, or another duly qualified
and equipped professional for further information when replacing tires or
wheels.
Handling of tires and the suspension
Using tires with any kind of problem or modifying the suspension will
affect the driving assist systems, and may cause a system to malfunction.

Hill-start assist control
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 while the slip indicator light
is illuminated.
Hill-start assist control helps to prevent the vehicle from rolling back-
wards when starting on an incline or slippery slope.
To engage hill-start assist
control, further depress the
brake pedal when the vehicle
is stopped completely.
A buzzer will sound once to
indicate the system is acti-
vated. The slip indicator will
also start flashing.

Hill-start assist control
While hill-start assist control is operating, the brakes remain automati-
cally 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 system still does not operate, check if the operat-
ing 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 within approximately 2 sec-
onds 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.
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.

PCS (Pre-Crash Safety system)
: If equipped
When the radar sensor detects possibility 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.
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 control of the vehicle. (P. 1 1 0 )
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 display and buzzer.
If the system determines that a collision is unavoidable, the brakes
are automatically applied to reduce the collision speed. Pre-crash
