●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. 

■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

■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 vehicle is stuck
