OBD (On Board Diagnostics) checks. The OBD system monitors the oper-
ation of the emission control system.

LX570_OM_OM60L21U_(U) CAUTION■
Used engine oil ●
Used engine oil contains potentially harmful contaminants which may cause skin
disorders such as inflammati on or skin cancer, so care should be taken to avoid
prolonged and repeated contact. To remove used engine oil from your skin, wash
thoroughly with soap and water. ●
Dispose of used oil and filters only in a safe and acceptable manner. Do not dis-
pose of used oil and filters in household trash, in sewers or onto the ground. Call
your Lexus dealer, service station or auto parts store for information concerning
recycling or disposal. ●
Do not leave used engine oil within the reach of children.
NOTICE■
To prevent serious engine damage
Check the oil level on regular basis. ■
When replacing the engine oil ●
Be careful not to spill engine oil on the vehicle components. ●
Avoid overfilling, as the engine could be damaged. ●
Check the oil level on the dipstick every time you refill the vehicle. ●
Be sure the engine oil filler cap is properly tightened.

LX570_OM_OM60L21U_(U) NOTICE■
Repairing or replacing tires, wheels, tire pressure warning valves and transmit-
ters and tire valve caps ●
When removing or fitting the wheels, tires or the tire pressure warning valve and
transmitter, contact your Lexus dealer as the tire pressure warning valve and
transmitter may be damaged if not handled correctly. ●
Make sure to install the tire valve caps. If the tire valve caps are not installed,
water could enter the tire pressure warning valves and the tire pressure warning
valves could be bound. ●
When replacing tire valve caps, do not us e tire valve caps other than those speci-
fied. The cap may become stuck.■
To avoid damage to the tire pressure warning valves and transmitters
When a tire is repaired with liquid seal ants, the tire pressure warning valve and
transmitter may not operate properly. If a liquid sealant is used, contact your Lexus
dealer or other qualified service shop as so on as possible. Make sure to replace the
tire pressure warning valve and transmitter when replacing the tire. ( P. 76 3 )■
Driving on rough roads
Take particular care when driving on roads with loose surfaces or potholes.
These conditions may cause losses in tire inflation pressure, reducing the cushion-
ing ability of the tires. In addition driving on rough roads may cause damage to the
tires themselves, as well as the vehicle’s wheels and body.■
If tire inflation pressures become low while driving
Do not continue driving, or your tires and/or wheels may be ruined.

7764-3. Do-it-yourself maintenance
LX570_OM_OM60L21U_(U) ■
When replacing wheels
The wheels of your Lexus are equipped with tire pressure warning valves and trans-
mitters that allow the tire pressure warning system to provide advanced warning in
the event of a loss in tire inflation pres sure. Whenever wheels are replaced, the tire
pressure warning valves and transmitters must be installed. ( P. 76 3 )
CAUTION■
When replacing wheels ●
Do not use wheels that are a different size from those recommended in the
Owner’s Manual, as this may result in loss of handling control.●
Never use an inner tube in a leaking wheel which is designed for a tubeless tire.
Doing so may result in an accident , causing death or serious injury.■
Use of defective wheels prohibited
Do not use cracked or deformed wheels.
Doing so could cause the tire to leak air during driving, possibly causing an acci-
dent.
NOTICE■
Replacing tire pressure warning valves and transmitters ●
Because tire repair or replacement may affect the tire pressure warning valves
and transmitters, make sure to have tires serviced by your Lexus dealer or other
qualified service shop. In addition, make sure to purchase your tire pressure
warning valves and transmitters at your Lexus dealer. ●
Ensure that only genuine Lexus wheels are used on your vehicle.
Tire pressure warning valves and transmitters may not work properly with non-
genuine wheels.
