CAUTION■
When using Crawl Control and Turn Assist function
Do not rely solely on the Crawl Control an d Turn Assist function. This function does
not extend the vehicle’s performance limi tations. Always thoroughly check the
road conditions, and drive safely. ■
These conditions may cause the system not to operate properly
When driving on the following surfaces, th e system may not be able to maintain a
fixed low speed, which may result 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.

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 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 driving
LX570_OM_OM60L96U_(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 br aking 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 driv e power and prevent the 4 wheels from spinning
when starting the vehicle or a ccelerating on slippery roads.
■ Hill-start assist control Helps to prevent the vehicle from ro lling backwards when starting on an
incline or slippery slope.
■ VGRS (Variable Gear Ratio Steering) Helps to adjust the wheel turning an gle in accordance with the vehicle
speed and steering wheel movement.
■ PCS (Pre-Collision System) (if equipped)  P. 357

LX570_OM_OM60L96U_(U) When the VSC/Trailer Sway Cont rol/Active TRAC/hill-start assist
control systems are operating
The slip indicator light flashes to
indicate that the VSC/Trailer
Sway Control/Active TRAC/hill-
start assist control systems have
been engaged. The stop lights and high mounted
stoplight turn on when the hill-start
assist control system or Trailer
Sway Control is operating.■ Trailer Sway Control Helps the driver to control trailer sway by selectively applying brake pres-
sure for individual wheels and reducing engine torque when trailer sway is
detected.
Trailer Sway Control is part of th e VSC system and will not operate if
VSC turned off or expe riences a malfunction.
