on.
When in constant speed control
mode, to return to vehicle-to-vehi-
cle distance control mode, push
the lever forward again and hold
for approximately 1 second.
After the desired speed has been
set, it is not possible to return to
vehicle-to-vehicle distance control
mode.
If the “ENGINE START STOP”
switch is turned off and then turned
to IGNITION ON mode again, the
vehicle will automatically returns to
vehicle-to-vehicle distance control
mode.

■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).
■Accelerating after setting the vehicle speed
The vehicle can be accelerated 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 (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
reason, there may be a malfunction in the system. Contact your Lexus dealer.

■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 VSC 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 select 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 current 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 the vehicle is stuck
Switching the transfer and differential
For the operation of the following functions, refer to the following pages.
●Four-wheel drive system ( →P. 3 2 6 )

Multi-terrain Monitor∗
∗: If equipped
The Multi-terrain Monitor displays the vehicle surroundings when driving
at low speeds, thus assisting off-ro ad driving and helping the driver to
check the vehicle surroundings.
The Multi-terrain Monitor displays the vehicle surroundings automati-
cally when a mode is being selected on the Multi-terrain Select.
● You can switch between 4 different images (front, side-front, side-
rear and rear) by operating the switch.
● By using the front and side monitors to identify objects in the vicinity
or path of the tires, you can help to prevent the vehicle from becom-
ing stuck unexpectedly while driving.

CAUTION
■Selecting the correct height mode
●HI mode should only be used when driving on rough roads, for example when
driving off-road. Because the vehicle’s center of gravity will become higher when
in the mode, the vehicle may become unstable when turning abruptly, resulting in
an accident.
●Do not select HI mode when loading cargo on the roof luggage carrier.
Because the vehicle’s center of gravity will become higher when in the mode, the
vehicle may become unstable when turning abruptly, resulting in an accident.
●Before lowering vehicle height, check that there is no one under the vehicle.
NOTICE
■Be careful in any place where overhead space is limited
The vehicle height will rise when a higher mode is selected or cargo is unloaded.
This may cause damage to the vehicle.
■Do not select LO mode when driving on bumpy roads
If the underbody of the vehicle touches a rugged road surface, the vehicle may be
damaged.
■Changing vehicle height
Do not change vehicle height frequently.
The compressor may overheat and stop operation.
■When on the extremely uneven roads with rocks
Sometimes the vehicle height is not adjusted because it is judged as uneven road
driving.

At that time, the buzzer will sound, the slip indicator turns off, and the Crawl Con-
trol indicator flashes.
A notification will be displayed on the multi-information display for several seconds.
(→ P. 7 0 5 )
●When the shift lever is moved to P or N.
●When the four-wheel drive control switch is in H4.
●When the driver’s door is opened.
When turning off Crawl Control while traveling, stop the vehicle before the Crawl
Control indicator turns off, or drive extremely carefully.
■Function limit
●In the following situations, you will be able to use brake control to drive downhill
at a fixed low speed, but you will be unable to use engine control to drive uphill
at a fixed low speed.
• When the driving mode is set to second start mode.
• When the vehicle speed is higher than 6 mph (10 km/h).
●In the following situation, engine control and brake control will stop temporarily:
At that time, the Crawl Control indicator flashes.
When the vehicle speed is higher than 15 mph (25 km/h).
■When the Crawl Control system is operated continuously
This may cause the brake actuator to overheat. In this case, the Crawl Control sys-
tem will stop operating, a buzzer will sound, the Crawl Control indicator will turn off
after flashing and the TRAC OFF will be shown on the multi-information display. In
this case, quickly stop the vehicle in a safe place and give the actuator adequate
time to cool off. Refrain from using the system until the message goes off. (The vehi-
cle can be driven normally during this time.)

■Operating tips
The system will operate when the shift lever is in a position other than P, however to
make effective use of the system it is recommended that the shift lever be shifted to
2 or 1 range of S mode.
■If the four-wheel drive control switch is in H4
The system does not operate.
■When the downhill assist control system is operated continuously
This may cause the brake actuator to overheat. In this case, the downhill assist con-
trol system will stop operating, a buzzer will sound and the DAC indicator will start
flashing, and the TRAC OFF will be shown on the multi-information display. Refrain
from using the system until the DAC indicator stays on and the message goes off.
(The vehicle can be driven normally during this time.)
■Sounds and vibrations caused by the DAC
●A sound may be heard from the engine compartment when the engine is
started or just after the vehicle begins to move. This sound does not indicate that
a malfunction has occurred in DAC.
●Either of the following conditions may occur when the DAC is operating. None
of these are indicators that a malfunction has occurred.
• Vibrations may be felt through the vehicle body and steering.
• A motor sound may be heard after the vehicle comes to a stop.
■System malfunction
●The DAC indicator does not come on when the “ENGINE START STOP”
switch is turned to IGNITION ON mode.
●The “DAC” indicator does not come on when the “DAC” switch is pressed.
●The slip indicator comes on.
In the above cases, have your vehicle checked by your Lexus dealer.
