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.

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
Rear GAWR
(With brakes)

3922-5. Driving information
LX570_OM_OM60L21U_(U) ● Avoid jerky starts or sudden acceleration.
● Avoid jerky steering and sharp turns, and slow down before making a
turn.
● Note that when making a turn, the tr ailer wheels will be closer than the
vehicle wheels to the inside of the turn. Co mpensate by making a
wider than normal turning radius.
● Slow down before making a turn, in crosswinds, on wet or slippery sur-
faces, etc.
Increasing vehicle speed ca n destabilize the trailer.
● Take care when passing other vehi cles. Passing requires considerable
distance. After passing a vehicle, do not forget the length of your
trailer, and be sure you have plenty of room before changing lanes.
● To maintain engine braking efficiency and charging system perfor-
mance when using engine braking, do not put the transmission in “D”.
If in the S mode, the transmission shift range position must be in 5 or
lower.
● Instability happens more frequently when descending steep or long
downhill grades. Before descending, slow down and downshift. Do not
make sudden downshifts while descending steep or long downhill
grades.
● Avoid holding the brake pedal down too long or applying the brakes
too frequently. This could cause th e brakes to overheat and result in
reduced braking efficiency.
● Due to the added load of the trailer, your vehicle’s engine may overheat
on hot days (at temperatures over 85°F [30°C]) when driving up a
long or steep grade. If the eng ine coolant temperature gauge indicates
overheating, immediately turn off th e air conditioning (if in use), pull
your vehicle off the road and stop in a safe spot. (  P. 873)

When driving
LX570_OM_OM60L21U_(U) ● Always place wheel bloc ks under both the vehi cle’s and the trailer’s
wheels when parking. Apply the pa rking brake firmly, and put the
transmission in “P”. Avoi d parking on a slope, bu t if unavoidable, do so
only after performing the following:
Apply the brakes and keep them applied.
Have someone place wheel blocks under both the vehicle’s and
trailer’s wheels.
When the wheel blocks are in pl ace, release the brakes slowly
until the blocks absorb the load.
Apply the parking brake firmly.
Shift into “P” and turn off the engine.
● When restarting after parking on a slope:
With the transmission in “P”, start the engine. Be su re to keep the
brake pedal pressed.
Shift into “D” or “R” (if reversing).
Release the parking brake and br ake pedal, and slowly pull or
back away from the wheel blocks. Stop and apply the brakes.
Have someone retrieve the blocks. STEP 1

AVS (adaptive variable suspension system)
The suspension can be switched for improvement in driveability. (  P. 3 2 9 )■
Break-in schedule
If your vehicle is new or equipped with any new power train components (such as
an engine, transmission, differential or wheel bearing), Lexus recommends that you
do not tow a trailer until the vehicle has been driven for over 500 miles (800 km).
After the vehicle has been driven for over 500 miles (800 km), you can start tow-
ing. However, for the next 500 miles (800 km), drive the vehicle at a speed of less
than 50 mph (80 km/h) when towing a traile r, and avoid full throttle acceleration.■
Maintenance ●
If you tow a trailer, your vehicle will require more frequent maintenance due to
the additional load. (See “Owner’s Guide”, “Warranty and Services Guide”,
“Owner’s Manual Supplement” or “Warranty Booklet”.) ●
Retighten the fixing bolts of the towing ball and bracket after approximately
600 miles (1000 km) of trailer towing.■
If trailer sway occurs
One or more factors (crosswinds, passing vehicles, rough roads, etc.) can adversely
affect handling of your vehicle and trailer, causing instability. ●
If trailer swaying occurs:
• Firmly grip the steering wheel. Steer straight ahead.
Do not try to control trailer swaying by turning the steering wheel.
• Begin releasing the accelerator peda l 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. (if enabled, Trailer Sway Control can also help to stabilize the
vehicle and trailer.)

3962-5. Driving information
LX570_OM_OM60L21U_(U) ●
After the trailer swaying has stopped:
• Stop in a safe place. Get all occupants out of the vehicle.
• Check the tires of the vehicle and the trailer.
• Check the load in the trailer.
Make sure the load has not shifted.
Make sure the tongue weight is appropriate, if possible.
• Check the load in the vehicle.
Make sure the vehicle is not ov erloaded after occupants get in.
If you cannot find any problems, the speed at which trailer swaying occurred is
beyond the limit of your particular vehicle-trailer combination.
Drive at a lower speed to prevent instability. Remember that swaying of the towing
vehicle-trailer increases as speed increases.
CAUTION■
Trailer towing precautions ●
To tow a trailer safely, use extreme care and drive the vehicle in accordance with
the trailer’s characteristics and operating conditions. Failure to do so could cause
an accident resulting in death or seriou s injury. Vehicle stability and braking per-
formance are affected by trailer stability, brake setting and performance, and the
hitch. Your vehicle will handle differently when towing a trailer.●
Set the vehicle height to the “LO” mode and turn off the 4-Wheel AHC when you
connect a trailer, otherwise the vehicle height may change due to the automatic
leveling function, and you may catch part of your body in the vehicle, resulting in
an accident. (  P. 3 1 8 )
