■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 cabin decreases and the temperature around
the camera sensor becomes suitable for its operation, the functions will begin to
operate.
■Warning lights and messages for LDA
Warning lights and messages are used to indicate a system malfunction or to inform
the driver of the need for caution while driving. (→P. 700)
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 restarting the engine, have your vehicle inspected
by your Lexus dealer.

■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

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.
