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

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) 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.

When driving
LX570_OM_OM60L96U_(U) CAUTION■
To avoid accident or injury ●
Do not exceed the TWR, unbraked TWR, GCWR, GVWR or GAWR. ●
If the gross trailer weight is over 2000 lb. (907 kg), a sway control device with
sufficient capacity is required. ●
If the gross trailer weight is over 5000 lb. (2268 kg), a weight distributing hitch
with sufficient capacity is required. ●
Adjust the tongue weight within the ap propriate range. Place heavier loads as
close to the trailer axle as possible. ●
Do not exceed 65 mph (104 km/h), the posted towing speed limit or the speed
limit for your trailer as set forth in your trailer owner’s manual, whichever is low-
est. Slow down sufficiently before making a turn, in crosswinds, on wet or slippery
surface, etc. to help avoid an accident. If you experience a vehicle-trailer instabil-
ity from reducing a certain speed, slow down and make sure you keep your vehi-
cle speed under the speed of whic h you experience the instability.●
Do not make jerky, abrupt or sharp turns. ●
Do not apply the brakes suddenly as you may skid, resulting in jackknifing and
loss of vehicle control. This is especially true on wet or slippery surfaces. ●
Do not exceed the trailer hitch assembly weight, gross vehicle weight, gross axle
weight and trailer tongue weight capacities. ●
Do not use cruise co ntrol when towing.●
Slow down and downshift before descendi ng steep or long downhill grades. Do
not make sudden downshifts while descending steep or long downhill grades. ●
Vehicle-trailer instability is more likely on steep long down hills. Before descend-
ing steep or long downhill grades, slow down and downshift. Do not make sud-
den downshifts when descending steep or long downhill grades. Avoid holding
the brake pedal down too long or applying the brakes too frequently. This could
cause the brakes to overheat and re sult in reduced braking efficiency.
