Matching trailer ball height to trailer coupler height
■
Before towing
Check that the following conditions are met: ●
Ensure that your vehicle’s tires are properly inflated. ( P. 8 8 9 )●
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 suspension , or other possible causes.●
The trailer cargo is securely loaded. ●
The rear view mirrors conform to all applicable federal, state/provincial or local
regulations. If they do not, 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 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 )

When driving
LX570_OM_OM60L21U_(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 appropriate 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 lowest.
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 which 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 control when towing. ●
Slow down and downshift before descending 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 sudden
downshifts when descending steep or lo ng downhill grades. Avoid holding the
brake pedal down too long or applying the brakes too frequently. This could
cause the brakes to overheat and result in reduced braking efficiency.

3982-5. Driving information
LX570_OM_OM60L21U_(U) CAUTION■
Hitch
Trailer hitch assemblies have different weight capacities established by the hitch
manufacturer. Even though the vehicle may be physically capable of towing a
higher weight, the operator must determin e the maximum weight rating of the par-
ticular hitch assembly and never exceed the maximum weight rating specified for
the trailer-hitch. Exceeding the maximum weight rating se t 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 unbraked 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 brak-
ing 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 wand ering 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. Direct ly splicing trailer li ghts may damage your
vehicle’s electrical system and cause a malfunction.

Maximum load of tire
Check that the number given by dividing the maximum load by 1.10 of the replace-
ment tire is greater than 1 /2 of the Gr oss Axle Weight Ratings (GAWR) of either
the front axle or the rear axle, whichever is greater.

Tire types
1 Summer tires
Summer tires are high-speed performance tires best suited to highway driving
under dry conditions. Since summer tires do not have the same traction perfor-
mance as snow tires, summer tires are inadequate for driving on snow-covered
or icy roads. For driving on snow-covered roads or icy roads, the use of snow tires
is recommended. When installing snow tires, be sure to replace all four tires.
2 All season tires
All season tires are designed to provide better traction in snow and to be ade-
quate for driving in most winter conditions , as well as for use year round. All sea-
son tires, however, do not have adequa te traction performance compared with
snow tires in heavy or loos e snow. Also, all season tires fall short in acceleration
and handling performance compared with summer tires in highway driving.
3Snow tires
For driving on snow-covered roads or ic y roads, we recommend using snow tires.
If you need snow tires, select tires of the same size, construction and load capac-
ity as the originally installed tires. Since your vehicle has radial tires as original
equipment, make sure your snow tires also have radial construction. Do not install
studded tires without first checking loca l regulations for possible restriction.
Snow tires should be installed on all wheels. ( P. 3 74 )For the GAWR, see the Certification Label.
For the maximum load of the tire, see the load
limit at maximum cold tire inflation pressure
mentioned on the sidewall of the tire.

Maintenance and care
LX570_OM_OM60L21U_(U) ■
Tire inflation pressure check interval
You should check tire inflation pressure every 2 weeks, or at least once a month.
Do not forget to check the spare. ■
Effects of incorrect tire inflation pressure
Driving with incorrect tire inflation pressure may result in the following: ●
Reduced fuel efficiency ●
Reduced driving comfort and tire life ●
Reduced safety ●
Damage to the drive train
If a tire needs frequent refilling, have it checked by your Lexus dealer. ■
Instructions for checking tire inflation pressure
When checking tire inflation pressure, observe the following: ●
Check only when the tires are cold.
If your vehicle has been parked for at least 3 hours and has not been driven for
more than 1 mile or 1.5 km, you will get an accurate cold tire inflation pressure
reading. ●
Always use a tire pressure gauge.
The appearance of the tire can be misleadi ng. In addition, tire inflation pressures
that are even just a few pounds off can degrade ride and handling.●
Do not bleed or reduce tire inflation pressure after driving. It is normal for the
tire inflation pressure to be higher after driving. ●
Never exceed the vehicle capacity weight.
Passengers and luggage weight should be placed so that the vehicle is bal-
anced.

Maintenance and care
LX570_OM_OM60L21U_(U) Wheels If a wheel is bent, cracked or heavily corroded, it should be replaced.
Otherwise, the tire may separate from the wheel or cause loss of handling
control.
■ Wheel selection
When replacing wheels, care should be taken to ensure that they
are equivalent to those removed in load capaci ty, diameter, rim
width, and inset
* .
Replacement wheels are available at your Lexus dealer.
* : Conventionally referred to as “offset”.
Lexus does not recommend using:
● Wheels of different sizes or types
● Used wheels
● Bent wheels that have been straightened
■ Aluminum wheel precautions
● Use only Lexus wheel nuts and wrenches designed for use with
your aluminum wheels.
● When rotating, repairing or changi ng your tires, check that the
wheel nuts are still tight after driving 1000 miles (1600 km).
● Be careful not to damage the aluminum wheels when using tire
chains.
● Use only Lexus genuine balance weights or equivalent and a
plastic or rubber hammer when balancing your wheels.
