■Dynamic radar cruise control can be set when
●The shift lever is in the D or range 4 or higher of S has been selected.
●Vehicle speed is above approximately 30 mph (50 km/h).
■Switching modes
The mode cannot be switched to constant speed control mode if vehicle-to-vehicle dis-
tance control mode has been used. The mode also cannot be switched from constant
speed control to vehicle-to-vehicle distance control mode. Turn the system off by press-
ing the “ON-OFF” button, and turn it on again.
■Accelerating after setting the vehicle speed
The vehicle can accelerate normally. After acceleration, the set speed resumes. How-
ever, during vehicle-to-vehicle distance control mode, the vehicle speed may decrease
below the set speed in order to maintain the distance to the vehicle ahead.
■Automatic cancelation of vehicl e-to-vehicle distance control
Vehicle-to-vehicle distance control driving is automatically canceled in the following situ-
ations:
●Actual vehicle speed falls below approximately 25 mph (40 km/h).
●VSC is activated.
●The sensor cannot operate correctly because it is covered in some way.
●The windshield wipers are oper ating at high speed (when the wiper switch is set to the
“AUTO” mode or the high speed wiper operation position).
●When second start mode is set.
●Bad weather causes the detection function to become extremely unstable.
●Multi-terrain mode is selected other than OFF.
●The center differential lock/unlock is not completed within 5 seconds while the
dynamic radar cruise control system is on.
If vehicle-to-vehicle distance control driving is automatically canceled for any other rea-
son, there may be a malfunction in the system. Contact your Lexus dealer.
■Automatic cancelation of constant speed control
The cruise control will stop maintaining the vehicle speed in the following situations:
●Actual vehicle speed is more than approximately 10 mph (16 km/h) below the set vehi-
cle speed.
At this time, the memorized set speed is not retained.
●Actual vehicle speed falls below approximately 25 mph (40 km/h).
●VSC is activated.
●The center differential lock/unlock is not completed within 5 seconds while the
dynamic radar cruise control system is on.

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.
■When the vehicle is stuck

CAUTION
■Conditions which may affect the Multi-terrain Monitor system
●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.
●Depending on the overall length of the vehicle (if a frontal protection system is
installed or the bumper has been replaced, etc.), the position of the distance guide-
lines displayed on the front monitor 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 using the Multi-terrain 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 the steering wheel is turned to full lock, the vehicle will turn
in the smallest possible turning circ le, and may collide with the obstacle.
●It may be difficult to judge distance with the image from the front camera due to the
characteristics of the lens. Drive carefully while checking the actual distance to the
obstacles displayed on the screen. Also, give your full attention to sudden bumps in
the road.
