LX570_OM_OM60L96U_(U) Trailer Tongue Weight
● A recommended tongue weight varies in accordance with the types of
trailers or towing as described below.
● To ensure the recommended values shown below, the trailer must be
loaded by referring to the following instructions.
• Tongue Weight
The gross trailer weight should be distributed so that the tongue
weight is 9% to 11%. (Tongu e weight/Gross trailer weight  100 =
9% to 11%)
Gross trailer weight
Tongue weight
If using a weight distributing hitc h when towing, return the front axle
to the same weight as be fore the trailer connection.
If front axle weight cannot be mea sured directly, measure the front
fender height above the front axle before connection. Adjust weight
distributing hitch torque until front fender is return ed to the same
height as before connection.
The gross trailer weight, gross axle weight and tongue weight can
be measured with platform scales found at a highway weighing sta-
tion, building supply company, tru cking company, junk yard, etc.

LX570_OM_OM60L96U_(U) Hitch
Trailer hitch assemblies have diff erent weight capacities. Lexus recom-
mends the use of Lexus hitch/bracket for your vehicle. For details, con-
tact your Lexus dealer.
● If you wish to install a trailer hitch, contact your Lexus dealer.
● Use only a hitch that conforms to the gros s trailer weight requirement
of your vehicle.
● Follow the directions supplied by the hitch manufacturer.
● Lubricate the hitch ball with a light coating of grease.
● Remove the trailer hitc h whenever you are not towing a trailer. After
removing the hitch, seal any mounting hole in the vehicle body to pre-
vent entry of any substances into the vehicle.
Removing hitch cover
Remove the clip.
Grasp the lower edge of the hitch
cover and raise the cover. When reattaching the cover,
reverse the steps listed.STEP 1

Use the correct trailer ball for your application.
Trailer ball load rating Matches or exceeds the gross
trailer weight rating of the trailer.
Ball diameter Matches the size of the trailer cou-
pler. Most couplers are stamped
with the required trailer ball size.
Shank length Protrudes beyond the bottom of
the lock washer and nut by at least
2 threads.
Shank diameter Matches the ball mount hole diam-
eter size.Trailer class Typical trailer ball
size
IV 2 5/16 in.
II and III 2 in.
I 1 7/8 in.

Matching trailer ball height to trailer coupler height
■
Before towing
Check that the following conditions are met: ●
Ensure that your vehicle’s ti res are properly inflated. (  P. 895)●
Trailer tires are inflated according to the trailer manufacturer’s recommenda-
tion. ●
All trailer lights work as required by law. ●
All lights work each time you connect them. ●
The trailer ball is set at the proper height for the coupler on the trailer. ●
The trailer is level when it is hitched.
Do not drive if the trailer is not level, and check for improper tongue weight,
overloading, worn suspensi on, or other possible causes.●
The trailer cargo is securely loaded. ●
The rear view mirrors conform to all appl icable federal, state/provincial or local
regulations. If they do no t, install rear view mirrors appropriate for towing pur-
poses. No matter which class of tow hitch applies,
for a more safe trailer hookup, the trailer ball
setup must be the proper height for the cou-
pler on the trailer.

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 overloaded after occupants get in.
If you cannot find any problems, the sp eed at which trailer swaying occurred is
beyond the limit of your partic ular vehicle-trailer combination.
Drive at a lower speed to prevent instability. Remember that swaying of the towing
vehicle-trailer increase s 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 stab ility and braking per-
formance are affected by trailer stability, brake setting and performance, and the
hitch. Your vehicle will handle d ifferently 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 auto-
matic leveling function, and you may catch part of your body in the vehicle, result-
ing in an accident. (  P. 320)

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.

4002-5. Driving information
LX570_OM_OM60L96U_(U) CAUTION■
Hitch
Trailer hitch assemblies have different weight capacities established by the hitch
manufacturer. Even though the vehicle ma y be physically capable of towing a
higher weight, the operator must determine the maximum weight rating of the par-
ticular hitch assembly and never exceed the maximum weight ra ting specified for
the trailer-hitch. Exceeding the maximum we ight rating set by the trailer-hitch man-
ufacturer can cause an accident resulting in death or serious personal injuries.■
When towing a trailer
Lexus recommends trailers with brakes that conform to any applicable federal and
state/provincial regulations. ●
If the gross trailer weight exceeds unbr aked TWR, trailer brakes are required.
Lexus recommends trailers with brakes that conform to all applicable federal and
state/provincial regulations. ●
Never tap into your vehicle’s hydraulic system, as this will lower the vehicle’s
braking effectiveness. ●
Never tow a trailer without using a safety chain securely attached to both the
trailer and the vehicle. If damage occurs to the coupling unit or hitch ball, there is
danger of the trailer wandering into another lane.
NOTICE■
When installing a trailer hitch
Use only the position recommended by your Lexus dealer. Do not install the trailer
hitch on the bumper; this may cause body damage. ■
Do not directly splice trailer lights
Do not directly splice trailer lights. Directly splicing trailer lights may damage your
vehicle’s electrical system and cause a malfunction.
