■Dynamic radar cruise control can be set when
●The shift lever is in D. (Recommended) 
Dynamic radar cruise control can also be set when the shift lever is in S and
range 4, 5 or 6 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
distance control mode has been used. The mode also cannot be switched from
constant speed control to vehicle-to-vehic le distance control mode. Turn the sys-
tem off by pressing the “ON-OFF” button, and turn it on again.
■Accelerating
The vehicle can accelerate normally. After acceleration, the set speed resumes.
However, 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 vehicle-to-vehicle distance control
Vehicle-to-vehicle distance control driving is automatically canceled in the follow-
ing situations:
●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 operating at high speed.
●The driving mode is set to second start mode.
●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
reason, 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 vehicle speed.
At this time, the memorized set speed is not retained.
●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.
■Vehicle-to-vehicle distance settings
Select a distance from the table below. Note that the distances shown correspond
to a vehicle speed of 50 mph (80 km/h). Vehicle-to-vehicle distance increases/
decreases in accordance with vehicle speed.
■Radar sensor and grille cover
Always keep the sensor and grille cover clean to ensure that the vehicle-to-vehicle
distance control operates properly. (Some obstructions, such as snow, ice and plas-
tic objects, cannot be detected by the obstruction sensor.) 
Dynamic radar cruise control is canceled if an obstruction is detected.
■Warning lights, messages and buzzer for dynamic radar cruise control
Warning lights, messages and buzzer ar e used to indicate a system malfunc-
tion or to inform the driver of th e need for caution while driving. ( P. 6 9 8 )

NOTICE
■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 the steering wheel is turned to full lock, the vehicle will
turn in the smallest possible turning circle, and may collide with the obstacle.

■The Multi-terrain Select can be operated when
●Vehicle speed is less than 7 mph (12 km/h)
●Crawl Control is off
■When using Multi-terrain Select
The following functions cannot be switched on or off.
●VSC
●Active TRAC
●Second start mode
A message will be shown on the multi-information display stating that these func-
tions cannot be switched using the VS C OFF switch or the menu and “ENTER”
switches.
■When selecting a terrain mode
If you are unsure which mode is appropriate, select MOGUL when the four-wheel
drive control switch is in L4 or se lect MUD & SAND when it is in H4.
■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 mode which provides a smaller amount
of tire slippage than the curr ent mode when the amount of tire slippage is large, or
conversely selecting a mode which provides a larger amount of tire slippage than
the current mode when the amount of tire slippage is small.

■When using the Multi-terrain Monitor
●Even if an obstacle is no longer visible on the side monitor, do not turn the steer-
ing wheel further in the direction the vehicle is turning until the vehicle has moved
completely past the obstacle. If the steerin g wheel is turned to full lock, the vehi-
cle will turn in the smallest possible turning circle, and may collide with the obsta-
cle.
●It may be difficult to judg e distance with the image fr om the front camera due to
the characteristics of the lens. Drive care fully while checking the actual distance
to the obstacles displayed on the screen. Also, give your full attention to sudden
bumps in the road.

Four-wheel drive system
Use the four-wheel drive control switch and center differential lock/unlock
switch to select the following transfer and center differential modes.
■Four-wheel drive control switch
H4 (high speed position)
Normal driving on all types of
roads.
L4 (low speed position)
Driving requiring maximum
power and traction such as
climbing or descending steep
hills, off-road driving, and hard
pulling in sand or mud, etc.
The low speed four-wheel
drive indicator will come on.

■Center differential lock/unlock switch
Lock the center differential
when your vehicle’s wheels get
stuck in a ditch or when driving
on a slippery or bumpy surface.
The center differential lock indi-
cator will come on.
Unlock the center differential
after the wheels have been
freed, or after moving to a flat,
non-slippery surface.
To unlock the center differential,
push the switch again.

■When the center differential lock/unlock switch can be operated
The “ENGINE START STOP” switch is in IGNITION ON mode.
■The center differential lock indicator light
●The indicator light blinks while lockin g/unlocking the center differential.
●If the center differential lock indicator light blinks and the buzzer sounds when
the center differential is locked, stop the slipping or spinning and push the
switch again.
If the indicator continue to blink even if doing so, have the vehicle inspected by your
Lexus dealer as soon as possible. There may be a trouble in the four-wheel drive
system.
■Locking/unlocking the center differential
●When the four-wheel drive control switch is in L4 with the center differential
locked, VSC is automatically turned off. (The center differential lock and VSC
OFF indicator light will come on.)
●If the operation is not completed, the center differential lock indicator blinks. If
the indicator light does not turn off when unlocking the center differential, drive
straight ahead while accelerating or decelerating, or drive in reverse.
●Avoid turning suddenly while the center diff erential is locked. If you do turn sud-
denly, the difference in turning speeds between the front and rear wheels may
have a similar effect to braking, thus making driving difficult.

CAUTION
■While driving
Observe the following precautions. Failure to do so may cause an accident result-
ing in death or serious injury.
●Never move the four-wheel drive control switch if the wheels have lost traction.
●Do not operate the center differential lock/unlock when the vehicle is turning or
when its wheels are spinning freely off the ground.
NOTICE
■To prevent damage to the center differential
●For normal driving on dry and hard surface roads, unlock the center differential.
●Unlock the center differential after the wheels are out of the ditch or off the slip-
pery or bumpy surface.
