●When the lane markers are only on one side of the road.
●When driving on a sharp curve.
●When lanes are extremely narrow or extremely wide.
●When the vehicle leans to one side an unusual amount due to a heavy load or
improper tire inflation pressure.
●When the following distance between your vehicle and the vehicle ahead is
extremely short.
●When the lane markers are broken or when “Botts’ dots” or “Raised pavement
markers” can be seen.

NOTICE
■Camera sensor
●Keep the windshield clean at all times.
LDA performance may deteriorate due to the presence of raindrops, condensa-
tion, ice or snow on the windshield.
●Do not subject the camera sensor to strong impact or force, and do not disas-
semble the camera sensor.
●Do not change the installation position of the camera sensor or remove it. The
direction of the camera sensor is precisely adjusted.
●When it is cold, using the heater with air blowing to the feet may cause the upper
part of the windshield to fog up. This will have a negative effect on the images. In
such a case, use the windshield defogger to provide warm, dry air to the wind-
shield.
●Do not place anything on the dashboard.
The camera sensor may recognize the image reflected on the windshield as lane
markings by mistake.
●Do not scratch the camera lens, or let it get dirty.
●Do not attach stickers or other items to the windshield near the camera sensor.
●Adjust the inside rear view mirror correctly so that it does not interfere with the
camera sensor.
Observe the following to ensure that the
LDA system functions correctly.

Rear view monitor system
The rear view monitor assists the driver by displaying an image of the area
behind the vehicle while reversing. The image is displayed in reverse on the
screen. This reversed image is a similar image to the one on the inside rear
view mirror.
The rear view image is displayed
when the shift lever is in the R
position.
If the shift lever is shifted out of
R, the screen returns to the pre-
vious one.
Accessory meter (vehicles
without navigation system) or
touch screen (vehicles with

■Rear view monitor camera
■When the back door is open
The screen cannot be used because a message is displayed.
When backing up the vehicle, make sure the back door is securely closed.The rear view monitor camera is located on
the back door as shown in the illustration. The
camera uses a special lens. The distance of
the image that appears on the screen differs
from the actual distance.
In the following cases, it may be difficult to
see images on the screen even when the sys-
tem is functioning correctly:
●The vehicle is in a dark area, such as at
night.
●The temperature near the lens is extremely
high or low.
●Water droplets are on the camera lens or
humidity is high, such as when it rains.
●Foreign matter, such as snow and mud,
adheres to the camera lens.
●The camera has scratches or dirt on it.
●The sun or headlights are shining directly
into the camera lens.

■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.
CAUTION
■When using the rear view monitor system
Observe the following precautions to avoid an accident that could result in death or
serious injuries:
●Never depend solely on the monitor system when reversing.
●Always check visually and with the mirrors to confirm your intended path is clear.
●Depicted distances between objects and flat surfaces differ from actual dis-
tances.
If a bright light, such as sunlight reflected off
the vehicle body, is picked up by the camera,
a smear effect
* characteristic to the camera
may occur.
*: Smear effect  A phenomenon that
occurs when a bright light is picked up by
the camera; when transmitted by the cam-
era, the light source appears to have a ver-
tical 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 changed. Have the vehicle inspected by your Lexus dealer.
●As the camera has a water proof construction, do not detach, disassemble or
modify it. This may cause incorrect operation.
●Rapid temperature changes, such as when hot water is poured on the vehicle 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.
●Do not strongly rub the camera lens. If the camera lens is scratched, it cannot
transmit a clear image.
●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.
●The displayed image may be darker and moving images may be slightly distorted
when the system is cold.
●Situations unsuitable for rear view monitor
• On icy or slick road surfaces, or in snow.
• When using tire chains or emergency tires.
• On roads that are not flat or straight, such as curves or slopes.
●When traveling on a sloping road, the area displayed on the screen may change.
●If the tires are changed, the area displayed on the screen may change.
●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.

Wide view front & side monitor∗
∗: If equipped
This system can display the wide view front monitor and the side monitor.
The wide view front monitor uses a super-wide angle lens to display on
screen the areas to the left and right of the vehicle and the blind spots to the
front of the vehicle. This system he lps the driver check for approaching
cars, bicycles and pedestrians when at intersections with poor visibility.
The side monitor uses a camera installed in the passenger’s side outside
rear view mirror to display on screen the area to the right of the vehicle,
helping the driver check this area.
Vehicles with a navigation system
Refer to the “Navigation System Owner’s Manual”.
