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 scre en 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 looking at the monitor screen under any circum-
stances.
Driving while only viewing the monitor sc reen may cause a collision or lead to an
accident, as the image displayed on the mo nitor 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 direct visually all around the vehicle before
proceeding.
●If the tires are changed, the position of th e 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.

NOTICE
■When a solid object is close by
■When using the wide view front & side monitor
Even if an obstacle is no longer visible on the side monitor, do not turn the steering
wheel further in the direction the vehicle
is turning until the vehicle has moved com-
pletely past the obstacle. If th e steering wheel is turned to full lock, the vehicle will turn
in the smallest possible turning circle, and may collide with the obstacle.
The screen’s guide lines are designed for level
surfaces (road surface etc.) or flat walls etc.
When driving near the obstacle, the obstacle
may be displayed as outside the projected
course line, and it may seem that there is no
danger of a collision, however any sections pro-
truding from the wall may project over the
course line and the vehicle may actually collide
with the obstacle.
In cases such as this were the projected course
line passes close to obstacles, always visually
check the surroundings for safety.

■When it is difficult
to generate traction
MUD & SAND mode provides the largest amount of tire slippage, followed by LOOSE
ROCK, MOGUL and ROCK mode.
Drivability can be improved by selecting a mo de which provides a smaller amount of tire
slippage than the current mode when the amount of tire slippage is large, or conversely
selecting a mode which provides a larger amou nt of tire slippage than the current mode
when the amount of tire slippage is small.

●Minimum projected turning circle & projected course line
Use the minimum projected turn-
ing circle & projected course line
(when displayed) to check the
vehicle’s path with relation to
obstacles.
If the minimum projected turning
circle line (blue) is over the obsta-
cle as shown in the illustration, or
the obstacle falls within the mini-
mum projected turning circle, if
you turn with the minimum possi-
ble turning circle, the vehicle may
collide with the object.
When the projected course line
(yellow) is displayed, be sure to
operate the steering wheel so
that the obstacle stays outside the
projected course line until the
vehicle has passed the object.
