■When the vehicle has been parked in the sun
The LDA system may not be available for a while after driving has started. In such
cases, turn the LDA system off and turn it on again after normal temperature
returns. When the temperature in the cab in decreases and the temperature around
the camera sensor becomes suitable for it s operation, the functions will begin to
operate.
■Warning lights and messages for LDA
Warning lights and messages are used to in dicate a system malfunction or to inform
the driver of the need for caution while driving. ( P. 705)
CAUTION
■Before using the LDA system
This system provides information to the driver in accordance with the road geome-
try and the driving conditions. Be aware of your surroundings at all times, correct
the driving path while driving appropriately and be responsible for your own safety.
This system operates by using the camera to identify lane markers when the LDA
switch is on and the vehicle is being driven at the system operating speed.
Operation may be temporarily suspended if the camera cannot recognize the lane
markers or if the system cannot operate due to the road environment or driving
conditions. Also, since an alarm may sound unnecessarily if the lane markers cannot
be correctly identified, make sure to drive responsibly even while the system is
operating.
If a malfunction occurs in the system, the driver will be alerted by a buzzer and a dis-
play, and LDA operation will be temporarily suspended. However, this does not
present a problem to normal driving.
If the alert is displayed even after restarti ng the engine, have your vehicle inspected
by your Lexus dealer.

NOTICE
■In the following situations, the LDA will not work, or will not perform reliably
●When the lane markers are interrupted or are not present, such as before a toll-
booth.
●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.
●When the lane markers are obscured or partially obscured by sand, dirt, etc.
●When driving on a particularly bright road surface, such as concrete.
●When driving on a road surface that is bright due to reflected light.
●When driving in a location where the light level changes rapidly, such as the
entrance to or exit from a tunnel.

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 simila r 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.
