LX570_OM_OM60L96U_(U) CAUTION■
While driving
Never move the four-wheel drive control switch if the wheels have lost traction.
Doing so may cause an accident resulting in death or serious injury. ■
When the vehicle is parked
If the shift lever is moved before the low speed four-wheel drive indicator turns on/
off, the transfer mode may not be shifted completely. The transfer mode disengages
both the front and rear driveshafts from the powertrain and al lows 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 se riously injured. You must complete the shifting of the
transfer mode. ( P. 332)
NOTICE■
To prevent damage to the center differential ●
For normal driving on dry an d hard surface roads, unlock the center differential.●
Unlock the center differential after the wh eels are out of the ditch or off the slip-
pery or bumpy surface. ●
Do not push the center differential lock/u nlock switch when the vehicle is turning
or when its wheels are spinning freely off the ground.

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
