When driving
LX570_OM_OM60L21U_(U) CAUTION■
Driving with snow tires
Observe the following precautions to reduce the risk of accidents.
Failing to do so may result in a loss of vehicle control and cause death or serious
injury. ●
Use tires of the size specified for your vehicle. ●
Maintain the recommended level of tire inflation pressure. ●
Do not drive in excess of 75 mph (120 km/h), regardless of the type of snow tires
being used. ●
Snow tires should be installed on all wheels.■
Driving with tire chains
Observe the following precautions to reduce the risk of accidents.
Failing to do so may result in the vehicle being unable to be driven safely, and may
cause death or serious injury. ●
Do not drive in excess of the speed limit specified for the tire chains being used or
30 mph (50 km/h), whichever is lower. ●
Avoid driving on bumpy road surfaces or over potholes. ●
Avoid sudden acceleration, abrupt steeri ng, sudden braking and shifting opera-
tions that cause sudden engine braking. ●
Slow down sufficiently before entering a curve to ensure that vehicle control is
maintained.■
When installing tire chains
Turn off the vehicle height control.
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 )

LX570_OM_OM60L21U_(U) Trailer towing tips
Your vehicle will handle differently when towing a trailer. In order to avoid
an accident, death or serious injury, k eep the following in mind when tow-
ing:
● Speed limits for towing a trailer va ry by state or province. Do not
exceed the posted towing speed limit.
● Lexus recommends that the vehicle-trailer speed limit is 65 mph (104
km/h) on a flat, straight, dry road. Do not exceed this limit, the posted
towing speed limit or the speed limit for your trailer as set forth in your
trailer owner’s manual, whichever is lowest. Instability of the towing
vehicle-trailer combination (trailer sway) increases as speed increases.
Exceeding speed limits may cause loss of control.
● Before starting out, check the trail er lights, tires and the vehicle-trailer
connections. Recheck after driving a short distance.
● Practice turning, stopping and reversing with th e trailer attached in an
area away from traffic until you be come accustomed to the feel of the
vehicle-trailer combination.
● Reversing with a trailer attached is difficult and requires practice. Grip
the bottom of the steering wheel and move your hand to the left to
move the trailer to the left. Move yo ur hand to the right to move the
trailer to the right. (This is gene rally opposite to reversing without a
trailer attached.) Avoid sharp or prolonged turning. Have someone
guide you when reversing to redu ce the risk of an accident.
● As stopping distance is increased when towing a trailer, vehicle-to-
vehicle distance should be increas ed. For each 10 mph (16 km/h) of
speed, allow at least one vehicle and trailer length.
● Avoid sudden braking as you may skid , resulting in the trailer jackknif-
ing and loss of vehicle control. This is especially true on wet or slippery
surfaces.

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.

■ 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
inflation pressure if not rotated.
■ Tire rotation
Rotate the tires in the order
shown. To equalize tire wear and extend
tire life, Lexus recommends that
tire rotation is carried 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. 76 3 )
■ The tire pressure warning system
Your Lexus is equipped with a tire pressure warning system that uses
tire pressure warning valves and tr ansmitters to detec t low tire infla-
tion pressure before serious problems arise. (  P. 8 2 4 )Front

Maintenance and care
LX570_OM_OM60L21U_(U) Installing tire pressure warning valves and transmitters
When replacing tires or wheels, tire pressure warning valves and trans-
mitters must also be installed.
When new tire pressure warning va lves and transmitters are installed,
new tire pressure warning valve and transmitter ID codes must be regis-
tered in the tire pressure warning computer and tire pressure warning
system must be initialized. Have tire pressure warning valve and transmit-
ter ID codes registered by your Lexus dealer. (  P. 76 4 )
Initializing the tire pressure warning system
■ The tire pressure warning system must be initialized in the following
circumstances:
● When the set tire pressure has been changed before towing.
(  P. 8 8 9 )
● When rotating the tires in above situation.
When the tire pressure warning sy stem is initialized, the current tire
inflation pressure is set as the benchmark pressure.

7644-3. Do-it-yourself maintenance
LX570_OM_OM60L21U_(U) ■ How to initialize the tire pressure warning system
Park the vehicle in safe plac e and turn the “ENGINE START
STOP” switch to OFF. While the vehicle is moving, initialization is not performed.
Adjust the tire inflation pressure to the specified co ld tire inflation
pressure level. (  P. 8 8 9 )Make sure to adjust the tire pressure to the specified cold tire inflation
pressure level. The tire pressure warning system will operate based on
this pressure level.
Turn the “ENGINE START STOP” switch to IGNITION ON
mode.
Push and hold the tire pressure
warning reset switch until the tire
pressure warning light blinks
slowly 3 times and a message
appears on the multi-information
display.
Wait for a few minutes with the IGNITION ON mode, and then
turn the “ENGINE START STOP” switch to OFF.
Registering ID codes
The tire pressure warning valve and transmitter is equipped with a unique
ID code. When replacing a tire pressu re warning valve and transmitter, it
is necessary to register the ID code of tire pressure warning valve and
transmitter. Have the ID code re gistered by your Lexus dealer.STEP 1
