■Cruise control can be set when
●The shift lever is in D or 4, 5 or 6 range of S has been selected.
●Vehicle speed is above approximately 25 mph (40 km/h).
■Accelerating
The vehicle can be accelerated normally. After acceleration, the set speed
resumes.
■Automatic cruise control cancelation
Cruise control will stop maintaining the ve hicle 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 malfun ction in the cruise control system. Have
the vehicle inspected by your Lexus dealer.

■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 )

■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 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.

Driving assist systems
To help enhance driving safety and performance, the following systems
operate automatically in response to various driving situations. Be aware,
however, that these systems are supplementary and should not be relied
upon too heavily when operating the vehicle.
■ABS (Anti-lock Brake System)
Helps to prevent wheel lock when the brakes are applied suddenly, or if
the brakes are applied while driving on a slippery road surface
■ Multi Terrain ABS (Anti-lock Br ake System) (vehicles with a
Multi-terrain Select system)
Helps to prevent wheel lock when the brakes are applied suddenly, or if
the brakes are applied while driving on a slippery road surface, or in off-
road conditions (such as rough roads, sand and mud)
The Multi Terrain ABS operates in synchronization with the Multi-terrain
Select
■ Brake assist
Generates an increased level of braking force after the brake pedal is
depressed when the system detects a panic stop situation
■VSC (Vehicle Stability Control)
Helps the driver to control skidding wh en swerving suddenly or turning on
slippery road surfaces

When the VSC/TRAC or Active TRAC/hill-start assist control systems
are operatingIf the vehicle is in danger of slip-
ping or rolling backward when
starting on an incline, or if any of
the drive wheels spins, the slip indi-
cator light flashes to indicate that
the VSC/TRAC or Active TRAC/
hill-start assist control systems are
operating.
A buzzer (intermittent) sounds to
indicate that VSC is operating.
The stop lights and high mounted
stoplight turn on when the hill-start
assist control system is operating.
