This mode employs a radar sensor to detect the presence of vehicles up to
approximately 400 ft. (120 m) ahead, determines the current vehicle-to-vehicle
following distance, and operates to main
tain a suitable following distance from
the vehicle ahead.
Note that vehicle-to-vehicle distance will close in when traveling on long downhill
slopes.
Example of constant speed cruising
When there are no vehicles ahead
The vehicle travels at the speed set by the driver. The desired vehicle-to-vehicle dis-
tance can also be set by operating th e vehicle-to-vehicle distance button.
Example of deceleration cruising and follow-up cruising
When a preceding vehicle driving slower than the set speed appears
When a vehicle is detected running ahead of you, the system automatically deceler-
ates your vehicle. When a greater reduction in vehicle speed is necessary, the system
applies the brakes (the stop lights will come on at this time). The system will respond to
changes in the speed of the vehicle ahead in order to maintain the vehicle-to-vehicle
distance set by the driver. Approach wa rning warns you when the system cannot
decelerate sufficiently to prevent your ve hicle from closing in on the vehicle ahead.
When the vehicle ahead of you stops, your ve hicle will also stop (vehicle is stopped by
system control). After the vehicle ahead starts off, pushing the cruise control lever up
or depressing the accelerator peda l will resume follow-up cruising.
Example of acceleration
When there are no longer any preceding vehicles driving slower than the set
speed
The system accelerates until the set speed is reached. The system then returns to con-
stant speed cruising.

■The center differential lock indicator light
The indicator light blinks while locking/unlocking the center differential.
■The center differential lock/unlock switch can be operated when
●The engine switch is in IGNITION ON mode.
●The vehicle speed is less than 62 mph (100 km/h).
■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
lights come on.)
●If the operation is not completed, the center di fferential lock indicator blinks. If the indi-
cator light does not turn off when unlocking the center differential, drive straight ahead
while accelerating or decelerating, or drive in reverse.
●If the center differential lock/unlock is not completed within 5 seconds while the cruise
control system is on, cancel the cruise control system.
■If the low speed four-wheel drive indicator light or the center differential lock indicator
light blinks
●If the low speed four-wheel drive indicator lig ht continues to blink when using the four-
wheel drive control switch, stop the vehicle completely, move the shift lever to N and
operate the switch again.
●If the shift lever is moved before the low sp eed four-wheel drive indicator turns on/off,
the transfer mode may not be shifted comp letely. The transfer mode disengages both
the front and rear driveshafts from the powertrain and allows the vehicle to move
regardless of the shift position. (At this time , the indicator blinks and the buzzer sounds.)
Therefore, the vehicle is free to roll even if the automatic transmission is in P. You or
someone else could be seriously injured. You must complete the shifting of the transfer
mode.
To complete the shifting, stop the vehicle completely, return the shift lever to N, and
confirm that the shift was completed (the indicator turns on/off).
●If the engine coolant temperature is too low, the four-wheel drive control system may
not be able to shift. When the engine is warmer operate the switch again.
If the low speed four-wheel drive indicator light or the center differential lock indicator
light continues to blink even after attempti ng the above, there may be a malfunction in
the engine, the brake system or the four-wheel drive system. In this case, you may not be
able to shift between H4 and L4, and the center differential lock may not be operable.
Have the vehicle inspected by your Lexus dealer immediately.

■Sounds and vibrations caused by the Crawl Control system
●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 Crawl Control system.
●Either of the following conditions may occur when the Crawl Control system is operat-
ing. 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.
■When there is a malfunction in the system
Warning lights and/or warning messages will turn on. ( P. 5 2 4 , 5 3 2 )

■When using Crawl Control and Turn Assist function
Do not rely solely on the Crawl Control and Turn Assist function. This function does not
extend the vehicle’s performance limitations. Always thoroughly check the road condi-
tions, and drive safely.
■These conditions may cause the system not to operate properly
When driving on the following surfaces, the sy stem may not be able to maintain a fixed
low speed, which may re sult in an accident:
●Extremely steep inclines.
●Extremely uneven surfaces.
●Snow-covered roads, or other slippery surfaces.
NOTICE
■When using Turn Assist function
The Turn Assist function is a function to assist turning performance when driving off
road. The function may be less effective on paved road surfaces.

■If you notice any symptoms
If you notice any of the following symptoms, refer to the likely cause and the
solution, and re-check.
If the symptom is not resolved by the solution, have the vehicle inspected by
your Lexus dealer.

■How to use the camera
●The Multi-terrain Monitor system may not operate properly in the following cases.
• If the front or the rear of the vehicle or the outside rear view mirror has been hit, the camera’s position and mounting angle may have changed.
• As the camera has a water proof construction, do not detach, disassemble or modify it. This may cause incorrect operation.
• Do not strongly rub the camera lens. If th e camera lens is scratched, it cannot
transmit a clear image.
• Do not allow organic solvent, car wax, window cleaner or glass coat to adhere to the camera. If this happens, wipe it off as soon as possible.
• If the temperature changes rapidly, such as when hot water is poured on the vehi- cle in cold weather, the system may not operate normally.
• 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.
• When the camera is used under fluorescen t lights, sodium light or mercury light
etc., the lights and the illuminate d areas may appear to flicker.
• The camera can be damaged by flying rocks and other debris.
●Do not expose the camera to strong impact as this could cause a malfunction. If this
happens, have the vehicle inspected by your Lexus dealer as soon as possible.
