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 conditions of the vehicle, trailer, road sur-
face, and driving environment, the Trailer Sway Control system may not be effec-
tive. Refer to your trailer owner’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 wheel. Steer straight ahead.
Do not try to control trailer sway ing by turning the steering wheel.●
Begin releasing the accelerator pedal im mediately 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. 395)

LX570_OM_OM60L21U_(U) Capacity and distribution
Cargo capacity depends on the to tal weight of the occupants.
(Cargo capacity) = (Total load capa city) — (Total weight of occupants)
Steps for Determining Correct Load Limit—
(1) Locate the statement “The combined weight of occupants and
cargo should never exceed XXX kg or XXX lbs.” on your vehicle’s
placard.
(2) Determine the combined weight of the driver and passengers that
will be riding in your vehicle.
(3) Subtract the combined weight of the driver and passengers from
XXX kg or XXX lbs.
(4) The resulting figure equals the av ailable amount of cargo and lug-
gage load capacity.
For example, if the “XXX” amount equals 1400 lbs. and there will be
five 150 lb passengers in your vehi cle, the amount of available cargo
and luggage load capacity is 650 lbs. (1400 - 750 (5  150) = 650
lbs.)
(5) Determine the combined weight of luggage and cargo being
loaded on the vehicle. That weight may not safely exceed the avail-
able cargo and luggage load capacity calculated in Step 4.
(6) If your vehicle will be towing a tr ailer, load from your trailer will be
transferred to your vehicle. Consu lt this manual to determine how
this reduces the available cargo an d luggage load capacity of your
vehicle. (  P. 373)

When driving
LX570_OM_OM60L21U_(U) Trailer towing Your vehicle is designed primarily as a passenger-and-load-carrying vehi-
cle. Towing a trailer can have an adverse impact on handling, performance,
braking, durability, and fuel consumpt ion. For your safety and the safety of
others, you must not overload your vehicle or trailer. You must also ensure
that you are using appropriate towing equipment, that the towing equip-
ment has been installed correctly and used properly, and that you employ
the requisite driving habits.
Vehicle-trailer stability and braking performance are affected by trailer
stability, brake performance and settin g, trailer brakes, the hitch and hitch
systems (if equipped).
To tow a trailer safely, use extreme care and drive the vehicle in accor-
dance with your trailer’s characteristics and operating conditions.
Lexus warranties do not apply to damage or malfunction caused by towing
a trailer for commercial purposes.
Contact your Lexus dealer for further information about additional
requirements such as towing kits, etc.

■ GCWR (Gross Combination Weight Rating)
The maximum allowable gross
combination weight. The gross
combination weight is the sum of
the total vehicle weight (including
the occupants, cargo and any
optional equipment installed on
the vehicle) and the weight of the
trailer being towed (including the
cargo in the trailer).
■ GVWR (Gross Vehicle Weight Rating)
The maximum allowable gross
vehicle weight. The gross vehicle
weight is the total weight of the
vehicle. When towing a trailer, it is
the sum of the vehicle weight
(including the occupants, cargo
and any optional equipment
installed on the vehicle) and the
tongue weight.

When driving
LX570_OM_OM60L21U_(U) ■ GAWR (Gross Axle Weight Rating)
The maximum allowable gross axle
weight. The gross axle weight is the
load placed on each axle (front
and rear).
■ TWR (Trailer Weight Rating)
The maximum allowable gross
trailer weight. The gross trailer
weight is the sum of the trailer
weight and the weight of the cargo
in the trailer.
TWR is calculated assuming base
vehicle with one driver, one front
passenger, towing package, hitch
and hitch systems (if required). Additional optional equipment,
passengers and cargo in the vehi-
cle will reduce the trailer weight
rating so as not to exceed GCWR,
GVWR and GAWR.
If the gross trailer weight exceeds
3000 lb. (1360 kg), it is recom-
mended to use a trailer with 2 or
more axles.Front GAWR
