■Cruise control can be set when
●The shift lever is in D or range 4 or higher of S has been selected.
●Vehicle speed is above approximately 25 mph (40 km/h).
■Accelerating after setting the vehicle speed
●The vehicle can be accelerated normally. After acceleration, the set speed
resumes.
●Even without cancelling the cruise control, the set speed can be increased by
first accelerating the vehicle to the desired speed and then pushing the lever
down to set the new speed.
■Automatic cruise control cancelation
Cruise control will stop maintaining the vehicle speed in any of the following situa-
tions:
●Actual vehicle speed falls more than 10 mph (16 km/h) below the preset vehicle
speed.
At this time, the memorized set speed is not retained.
●Actual vehicle speed is below approximately 25 mph (40 km/h).
●VSC is activated.
●The center differential lock/unlock is not completed within 5 seconds while the
cruise control system is on.
■If the cruise control indicator light flashes
Press the “ON-OFF” button once to deactivate the system, and then press the but-
ton again to reactivate the system.
If the cruise control speed cannot be set or if the cruise control cancels immediately
after being activated, there may be a malfunction in the cruise control system. Have
the vehicle inspected by your Lexus dealer.

■Dynamic radar cruise 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 the S posi-
tion and range 4 or higher 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.
■Set speed
The set speed may be unsustainable depending on driving circumstances.
■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 high speed wiper operation position).
●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.
●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.
■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 or plastic
objects, cannot be detected by the obstruction sensor.)
Dynamic radar cruise control is canceled if an obstruction is detected.
■Warning lights and messages for dynamic radar cruise control
Warning lights and messages are used to indicate a system malfunction or to inform
the driver of the need for caution while driving. (→P. 700)

■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
