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)

Maintenance and care
LX570_OM_OM60L96U_(U) Vehicle exterior Items Check points
Doors • Operate smoothly?
Engine hood • The lock system works properly?
Fluid leaks • Is there any leakage after parking?
Tires • Is the tire inflation pressure cor-
rect?
• The tires should not be damaged or
excessively worn.
• Have the tires been rotated
according to the maintenance
schedule?
• The wheel nuts should not be loose.
Windshield wipers/rear window
wiper • The wiper blades should not show
any signs of cracking, splitting,
wear, contamination or deforma-
tion.
• The wiper blades should clear the
windshield/rear window without
streaking or skipping.
CAUTION■
If the engine is running
Turn off the engine and ensure that there is adequate ventilation before performing
maintenance checks.

LX570_OM_OM60L96U_(U) Tires Replace or rotate tires in accordan ce with maintenance schedules and
treadwear.
■ Checking tires
New tread
Treadwear indicator
Worn tread The location of treadwear indi-
cators is shown by the “TWI” or
“ ” marks, etc., molded on the
sidewall of each tire.
Check spare tire condition and
pressure if not rotated.
■ Tire rotation
Rotate the tires in the order
shown. To equalize tire wear and
extend tire life, Lexus recom-
mends that tire rotation is car-
ried out at the same interval as
tire inspection.
Do not fail to initialize the tire
pressure warning system after
rotating the tires that the tire
pressure has been changed for
towing. (  P. 767)
■ The tire pressure warning system
Your Lexus is equipped with a tire pressure warning system that
uses tire pressure warning valves and transmitters to detect low tire
iflti bf i bl i ( P 829)Front

Maintenance and care
LX570_OM_OM60L96U_(U) Installing tire pressure warning valves and transmitters
When replacing tires or wheels, ti re pressure warning valves and trans-
mitters must also be installed.
When new tire pressure warning va lves and transmitters are installed,
new ID codes must be registered in the tire pressure warning computer
and the tire pressure warning system must be initialized. Have tire pres-
sure warning valve and transmitter ID codes registered by your Lexus
dealer. (  P. 768)
Initializing the tire pressure warning system
■ The tire pressure warning system must be initialized in the following
circumstances:
● When rotating the tires in above situation.
● When the set tire pressure has been changed before towing.
(  P. 895)
When the tire pressure warning sy stem is initialized, the current tire
inflation pressure is set as the benchmark pressure.

When to replace your vehicle’s tires
Tires should be replaced if: ●
You have tire damage such as cuts, splits, cracks deep enough to expose the
fabric, and bulges indicating internal damage ●
A tire goes flat repeatedly or cannot be properly repaired due to the size or
location of a cut or other damage
If you are not sure, consul t with your Lexus dealer.■
Replacing tires and wheels
If the ID code of the tire pressure warning valve and transmitter is not registered,
the tire pressure warning sy stem will not work properly. After driving for about 20
minutes, the tire pressure warning light come s on after blinking for 1 minute to indi-
cate a system malfunction. ■
When rotating the tires
Make sure that the “ENGINE START STOP” switch is off. If the tires are rotated
while the “ENGINE START STOP” switch is in IGNITION ON mode, the tire posi-
tion information will not be updated.
If this accidentally occurs, either turn the “ENGINE START STOP” switch to off
and then to IGNITION ON mode, or initia lize the system afte r checking that the
tire pressure is properly adjusted. ■
Tire life
Any tire over 6 years old mu st be checked by a qualified technician even if it has
seldom or never been used or damage is not obvious. ■
If the tread on snow tires wears down below 0.16 in. (4 mm)
The effectiveness of the tire s as snow tires is lost.

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-cover ed roads or icy roads, the use of snow
tires is recommended. When inst alling 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 loose 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 icy roads, we recommend using snow
tires. If you need snow tires, select ti res of the same size, construction and load
capacity as the originally installed tires. Si nce your vehicle has radial tires as orig-
inal equipment, make sure your snow tire s also have radial construction. Do not
install studded tires without first checking local regulations for possible restric-
tion. Snow tires should be installed on all wheels. (  P. 376)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.
