The SRS airbag and seat belt pretensioner devices in your Lexus contain explosive
chemicals. If the vehicle is scrapped with th e airbags and seat belt pretensioners left as
they are, this may cause an accident such as fire. Be sure to have the systems of the SRS
airbag and seat belt pretensioner removed and disposed of by a qualified service shop or
by your Lexus dealer befo re you scrap your vehicle.
Special handling may apply,
See www.dtsc.ca.gov/hazard ouswaste/perchlorate.
Your vehicle has components that may contain perchlorate. These components may

WARNING
■General precautions while driving
Driving under the influence: Never drive your vehicle when under the influence of
alcohol or drugs that have impaired your ability to operate your vehicle. Alcohol and
certain drugs delay reaction time, impair judgment and reduce coordination, which
could lead to an accident that could result in death or serious injury.
Defensive driving: Always driv e defensively. Anticipate mistakes that other drivers or
pedestrians might make and be ready to avoid accidents.
Driver distraction: Always give your full attention to driving. Anything that distracts the
driver, such as adjusting controls, talking on a cellular phone or reading can result in a
collision with resulting death or serious in jury to you, your occupants or others.
■General precaution regarding children’s safety
Never leave children unattended in the vehicl e, and never allow children to have or use
the key.
Children may be able to start the vehicle or sh ift the vehicle into neutral. There is also a
danger that children may injure themselves by play ing with the windows, the moon
roof, or other features of the vehicle. In addition, heat build-up or extremely cold tem-
peratures inside the vehicle can be fatal to children.

GX460_OM_OM60T19U_(U)4-5. Using the driving support systems
When all of the following conditions are
satisfied, the Multi-terrain Select indica-
tor will come on, the mode select screen will be displayed on the multi-informa-
tion display, and Multi-terr ain Select control will begin.
●The four-wheel drive control switch is in “L4”.
●Both Active TRAC and VSC are not off.
Operate the Multi-terrain Select mode
selector switch du ring Multi-terrain
Select control to select a mode.
Once the mode is confirmed, the mode
name will be displayed and the control
will switch.
■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 it is difficult to generate traction
MUD & SAND mode provides the largest amou nt of tire slippage, followed by LOOSE
ROCK, MOGUL, ROCK & DIRT and ROCK mode.
Drivability can be improved by selecting a mo de 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 amou nt of tire slippage than the current mode
when the amount of tire slippage is small.
■When the vehicle is stuck
Switching the transfer and differential
For the operation of the following func tions, refer to the following pages.
●Four-wheel drive system (P. 344)
●Center differential lock ( P. 345)
■When the brake system operates continuously
The brake system may overheat. In this case, a buzzer will sound, the TRAC OFF indica-
tor will flash, and Multi-terrain Select will be temporarily inoperable. In this event, stop
the vehicle immediately in a safe place, and allow the brake system to cool down suffi-
ciently. (There is no problem wi th continuing normal driving.)
After a short time, the TRAC OFF indicator will go off, and you will be able to use Multi-
terrain Select.

Four-wheel drive system
H4 (high speed position)
Normal driving on all types of roads.
L4 (low speed position)
Driving requiring maximum power and
traction such as climbing or descending
steep hills, off-road driving, and hard
pulling in sand or mud, etc.
The low speed four-wheel drive indica-
tor will come on.
Use the four-wheel drive control switch
and center differential lock/unlock
switch to select the following transfer and center differential modes.

Driving
■Locking/unlocking the center differential
●If the operation is not completed, the center di fferential lock indicator blinks. If the indi-
cator does not turn off when unlocking the center differential, drive straight ahead
while accelerating or decelera ting, or drive in reverse.
●Avoid turning suddenly while the center differ ential is locked. If you do turn suddenly,
the difference in turning speeds between the front and rear wheels may have a similar
effect to braking, thus making driving difficult.
WARNING
■While driving
Observe the following precautions. Failure to do so may cause an accident resulting in
death or serious injury.
●Never move the four-wheel drive control switch if the wheels have lost traction.
●Do not operate the center differential lock/unlock when the vehicle is turning or
when its wheels are spinning freely off the ground.
NOTICE
■To prevent damage to the center differential
●For normal driving on dry and hard surface roads, unlock the center differential.
●Unlock the center differential after the wheels are out of the ditch or off the slippery
or bumpy surface.

Driving
Driving assist systems
◆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
◆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 su
rface, or in off-road conditions (such as
rough roads, sand and mud)
Vehicles with Multi-terrain Select system: The Multi Terrain ABS operates in synchro-
nization with the Multi-terrain Select
◆Brake assist
Generates an increase d 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
◆TRAC (Traction Control) for H4 position
Helps to maintain drive power and prevent the drive wheels from spinning when start-
ing the vehicle or accelera ting on slippery roads
To keep driving safety and performance, the following systems operate auto-
matically in response to various drivin g situations. Be aware, however, that
these systems are supplementary and shou ld not be relied upon too heavily
when operating the vehicle.

GX460_OM_OM60T19U_(U)4-5. Using the driving support systems
◆Active TRAC (Traction Control) for L4 position*
Helps to maintain drive power and prevent the 4 wheels from spinning when starting
the vehicle or accelerating on slippe
ry roads, or in off-road conditions
*: The function only works in vehicles with Multi-terrain Sele ct when Multi-terrain
Select is switched on
◆Hill-start assist control
Helps to prevent the vehicle from rolling back ward when starting on an incline or slip-
pery slope
◆KDSS (Kinetic Dynamic Suspension System)
KDSS helps to enhance ride comfort and hand ling response by using a hydraulic con-
trol system to control the su spension stabilizer bars in response to road surface and
driving conditions during co rnering or off-road driving
◆Trailer Sway Control
Helps the driver to control trailer sway by selectively applying brake pressure for indi-
vidual wheels and reducing driving torque when trailer sway is detected.
The slip indicator light will flash while
the TRAC/Active TRAC/VSC/ABS/
