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

Sounds and vibrations caused by the Multi Terrain ABS, brake assist, Active
TRAC, VSC, Trailer Sway Control, hill-start assist control and VGRS●
A sound may be heard from the engine compartment when the engine is
started or just after the vehicle begins to move. This sound does not indicate that
a malfunction has occurred in any of these systems. ●
Any of the following conditions may oc cur when the above systems are operat-
ing. None of these indicates that a malfunction has occurred.
• Vibrations may be felt through the vehicle body and steering.
• A motor sound may be heard after the vehicle comes to a stop.
• The brake pedal may pulsate slightly after the Multi Terrain ABS is activated.
• The brake pedal may move down slightly after the Multi Terrain ABS is acti-
vated.■
Hill-start assist control is operational when ●
The shift lever is in “D” or “S”. ●
The brake pedal is not depressed.■
VGRS is disabled in the following situations ●
During stopping or the steering wheel has been moved for a long time while
driving at lower speeds. ●
After the engine is restarted at less than -22°F (-30°C).●
If you disconnect the battery with the steering wheel turned, the center position
of the steering wheel could be slightly and temporary changed. To initialize the
VGRS, drive for a short while.

Trailer Sway Control precaution
The Trailer Sway Control system is not able to reduce trailer sway in all situations.
Depending on many factors such as the cond itions of the vehicle, trailer, road sur-
face, and driving environment, the Trailer Sway Control system may not be effec-
tive. Refer to your trailer ow ner’s manual for information on how to tow your trailer
properly. ■
If trailer sway occurs
Observe the following precautions.
Failing to do so may cause death or serious injury.●
Firmly grip the steering wh eel. Steer straight ahead.
Do not try to control trailer swaying by turning the steering wheel. ●
Begin releasing the accelerator pedal immediately but very gradually to reduce
speed.
Do not increase speed. Do not apply vehicle brakes.
If you make no extreme correction with the steering or brakes, your vehicle and
trailer should stabilize. (  P. 397)

LX570_OM_OM60L96U_(U) CAUTION■
Off-road driving precautions
Always observe the following precautions to minimize the risk of serious personal
injury or damage to your vehicle: ●
Drive carefully when off the road. Do no t take unnecessary risks by driving in
dangerous places. ●
Do not grip the steering wheel spokes when driving off-road. A bad bump could
jerk the wheel and injure your hands. Keep both hands and especially your
thumbs on the outside of the rim. ●
Always check your brakes for effectiveness immediately after driving in sand,
mud, water or snow. ●
After driving through tall grass, mud, rock, sand, rivers, etc., ch eck that there is no
grass, bush, paper, rags, stone, sand, et c. adhering or trapped on the underbody.
Clear off any such matter fr om the underbody. If the vehicle is used with these
materials trapped or adhering to the underbody, a breakdown or fire could
occur. ●
When driving off-road or in rugged te rrain, do not drive at excessive speeds,
jump, make sharp turns, strike objects, etc. This may cause loss of control or vehi-
cle rollover causing death or serious in jury. You are also risking expensive dam-
age to your vehicle’s suspension and chassis.

LX570_OM_OM60L96U_(U) CAUTION■
Driving with snow tires
Observe the following precautions to reduce the risk of accidents.
Failing to do so may result in a loss of vehicle control and cause death or serious
injury. ●
Use tires of the size sp ecified for your vehicle.●
Maintain the recommended level of tire inflation pressure. ●
Do not drive in excess of 75 mph (120 km/h ), regardless of the type of snow tires
being used. ●
Snow tires should be in stalled on all wheels.■
Driving with tire chains
Observe the following precautions to reduce the risk of accidents.
Failing to do so may result in the vehicle being unable to be driven safely, and may
cause death or serious injury. ●
Do not drive in excess of the speed limit specified for the tire chains being used or
30 mph (50 km/h), whichever is lower. ●
Avoid driving on bumpy road surfaces or over potholes. ●
Avoid sudden acceleration, abrupt steering, sudden braking and shifting opera-
tions that cause sudden engine braking. ●
Slow down sufficiently before entering a curve to ensure that vehicle control is
maintained.■
When installing tire chains
Turn off the vehicle height control.
The vehicle height may change due to the automatic leveling function and you may
catch part of your body in the vehi cle, resulting in an accident. (  P. 320)

LX570_OM_OM60L96U_(U) Trailer towing tips
Your vehicle will handle differently when towing a trailer. In order to
avoid an accident, death or seriou s injury, keep the following in mind
when towing:
● Speed limits for towing a trailer vary by state or province. Do not
exceed the posted towing speed limit.
● Lexus recommends that the vehicle- trailer speed limit is 65 mph (104
km/h) on a flat, straight, dry road. Do not exceed this limit, the posted
towing speed limit or the speed limi t for your trailer as set forth in your
trailer owner’s manual, whichever is lowest. Inst ability of the towing
vehicle-trailer combination (tra iler sway) increases as speed
increases. Exceeding speed limits may cause loss of control.
● Before starting out, check the trailer lights, tires and the vehicle-trailer
connections. Recheck after driving a short distance.
● Practice turning, stopping and rever sing with the trailer attached in an
area away from traffic until you beco me accustomed to the feel of the
vehicle-trailer combination.
● Reversing with a trailer attached is difficult and requires practice. Grip
the bottom of the steering wheel and move your hand to the left to
move the trailer to the le ft. Move your hand to the right to move the
trailer to the right. (T his is generally opposite to reversing without a
trailer attached.) Avoid sharp or prolonged turning. Have someone
guide you when reversing to reduce the risk of an accident.
● As stopping distance is increased wh en towing a trailer, vehicle-to-
vehicle distance should be increas ed. For each 10 mph (16 km/h) of
speed, allow at least one vehicle and trailer length.
● Avoid sudden braking as you may skid, resulting in the trailer jackknif-
ing and loss of vehicle control. This is especially true on wet or slippery
surfaces.
