Automatic system cancelation
In the following situations, the Multi-terrain Select indicator will go off, and Multi-
terrain Select will be canceled automatically. ●
When the four-wheel drive control switch is in “H4”. ●
When Active TRAC and VSC are off. ●
When Crawl Control is on.■
When it is difficult to generate traction
MUD & SAND mode provides the largest amount of tire slippage, followed by
LOOSE ROCK, MOGUL, ROCK & DIRT and ROCK mode.
Drivability can be improved by selecting a mode which provides a smaller amount
of tire slippage than the cu rrent 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 driving
LX570_OM_OM60L21U_(U) 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.
■ Multi Terrain 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, or in off-
road conditions (such as rough roads, sand and mud).
■ 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 when swerving suddenly or turning on
slippery road surfaces.
■ Active TRAC (Traction Control) Helps to maintain drive power and prevent the 4 wheels from spinning
when starting the vehicle or accelerating on slippery roads.
■ Hill-start assist control Helps to prevent the vehicle from rolling backwards when starting on an
incline or slippery slope.
■ VGRS (Variable Gear Ratio Steering) Helps to adjust the wheel turning angle in accordance with the vehicle
speed and steering wheel movement.
■ PCS (Pre-Collision System) (if equipped)  P. 3 5 5

worn tires on a snow covered road). ●
The vehicle hydroplanes while driving at high speed on a wet or slick road.■
Stopping distance when the Multi Terrai n ABS is operating may exceed that of
normal conditions
The Multi Terrain ABS is not designed to shorten the vehicle’s stopping distance.
