LDA (Lane Departure Alert)∗
While driving on a road that has lane markers, this system recognizes the white
lane markers using a camera as a sensor to alert the driver when the vehicle
deviates from its lane.
If the system judges that the vehicle may deviate from its lane, it alerts the driver
using beeping and indications on the multi-information display.

CAUTION
■When using the rear view monitor system
The rear view monitor system is a supplemental device intended to assist the driver
when backing up. When backing up, be sure to check visually behind and all around
the vehicle before proceeding.
Observe the following precautions to avoid an accident that could result in death or
serious injuries.
●Never depend on the rear view monitor system entirely when backing up. The image
and the position of the guide lines displayed on the screen may differ from the actual
state.
Use caution, just as you would when backing up any vehicle.
●Be sure to back up slowly, depressing the brake pedal to control vehicle speed.
●The instructions given are only guide lines.
When and how much to turn the steering wh eel will vary according to traffic condi-
tions, road surface conditions, vehicle condit ion, etc. when parking. It is necessary to
be fully aware of this before using the rear view monitor system.
●When parking, be sure to check that the parking space will accommodate your vehi-
cle before maneuvering into it.
●Do not use the rear view monitor system in the following cases:
• On icy or slick road surfaces, or in snow
•When using tire chains
• When the back door is not closed completely
• On roads that are not flat or straight, such as curves or slopes.
●In low temperatures, the screen may darken or the image may become faint. The
image could distort when the vehicle is moving, or you may become unable to see the
image on the screen. Be sure to check direct visually and with the mirrors all around
the vehicle before proceeding.
●If the tire sizes are changed, the position of the fixed guide lines displayed on the
screen may change.
●The camera uses a special lens. The distances between objects and pedestrians that
appear in the image displayed on the scre en will differ from the actual distances.

CAUTION
■When using the wide view front & side monitor system
Observe the following precautions to avoid an accident that could result in death or
serious injuries.
●When attempting to use the side camera while the door mirror is folded in, the base
of the door mirror is displayed on the screen and the area in front of the vehicle can-
not be observed. The image displayed on the screen differs depending on the posi-
tion of the door mirror.
●The field of view of the camera is limited. Do not rely solely upon the wide view front &
side monitor.
As with unequipped vehicles, drive carefully while directly confirming the safety of
your surroundings.
●Always check visually to confirm your intended path is clear.
●The camera uses a special lens. The distances between objects and pedestrians that
appear in the image displayed on the sc reen will differ from the actual distances.
●When the monitor is in front view enlarged display mode, even if obstacles in the
image from the side monitor have disappeared, do not turn the steering wheel any
further until the vehicle has passed the obstacle. By turning the steering wheel further,
the vehicle may make a tight turn, causing the vehicle to make contact with the obsta-
cle.
●Do not drive the vehicle while only lookin g at the monitor screen under any circum-
stances.
Driving while only viewing the monitor screen may cause a collision or lead to an
accident, as the image displayed on the monitor screen may differ from actual condi-
tions. Make sure to visually check the surrounding areas with and without the mirror
while driving.
●Do not use the wide view front & side monitor in the following cases:
• On icy or slick road surfaces, or in snow.
• When the front passenger’s door is not closed completely
•When using tire chains
• On roads that is not flat, such as slopes
●In low temperatures, the screen may darken or the image may become faint. The
image could distort when the vehicle is moving, or you may become unable to see the
image on the screen. Be sure to check dire ct visually all around the vehicle before
proceeding.
●If the tires are changed, the position of the guide lines displayed on the screen may be
incorrect. When changing the tires, consult your Lexus dealer.
●Depending on the circumstances of the ve hicle (number of passengers, amount of
luggage, etc.), the position of the guide lines displayed on the screen may change. Be
sure to check visually behind and all around the vehicle before proceeding.
●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.
