Scheduled maintenance should be performed at specified intervals according to
the maintenance schedule.
For details about maintenance items and sche dules, refer to the “Lexus Service Book-
let” or “Lexus Warranty Booklet”.
What about do-it-yourself maintenance?
Many of the maintenance items are easy to do yourself if you have a little mechanical ability and a few basic automotive tools.
Note, however, that some maintenance task s require special tools and skills. These are best performed by qualified technicians. Even if you’re an experienced do-it-your-self mechanic, we recommend that repairs and maintenance be conducted by any
authorized Lexus dealer or repairer, or another duly qualified and equipped profes- sional. Any authorized Lexus dealer or repairer will keep a record of maintenance,which could be useful should you ever require Warranty Service. Should you choose
to select a qualified and equipped professional other than an authorized Lexus repairer to service or maintain your vehi cle, we recommend that you request that a
record of maintenance be kept.
Maintenance requirements
To ensure safe and economical drivin g, day-to-day care and regular mainte-
nance are essential. Lexus recommends the following maintenance:

WARNING
■Used engine oil
●Used engine oil contains potentially harmful contaminants which may cause skin dis- orders such as inflammation and skin cancer, so care should be taken to avoid pro-
longed 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 dispose of
used oil and filters in household trash, in sewers or onto the ground. Call any authorized Lexus dealer or repair er, or another duly qualified and equipped professional, service station or auto parts store for information concerning recycling
or disposal.
●Do not leave used engine oil within the reach of children.
NOTICE

Check the oil level on a regular basis.
■When replacing the engine oil
●Be careful not to spill engine oil on the vehicle components.
●Avoid overfilling, or 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.

4987-3. Do-it-yourself maintenance
RC300h_EE(OM24740E)
NOTICE
■Repairing or replacing tires, wheels, tire pressure warning valves, transmitters and tire valve caps
●When removing or fitting the wheels, tires or the tire pressure warning valves and
transmitters, contact any authorized Lexus de aler or repairer, or another duly quali- fied and equipped professional as the tire pressure warning valves and transmitters 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 valv es and the tire pressure warning valves could be bound.
●When replacing tire valve caps, do not use tire valve caps other than those specified.The cap may become stuck.
■To avoid damage to the tire pressure warning valves and transmitters
When a tire is repaired with liquid sealants, the tire pressure warning valve and trans- mitter may not operate properly. If a liquid sealant is used, contact any authorizedLexus dealer or repairer, or another duly qu alified and equipped professional or other
qualified service shop as soon as possible. After use of liquid sealant, make sure to replace the tire pressure warning valve and transmitter when repairing or replacing the tire. ( P. 486)
■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 cushioning
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.
■Low profile tires
Low profile tires may cause greater damage than usual to the tire wheel when sustain- ing impact from the road surface. Therefore, pay attention to the following:
●Be sure to use proper tire inflation pressu re. If tires are under-inflated, they may be
damaged more severely.
●Avoid potholes, uneven pavement, curbs an d other road hazards. Failure to do so may lead to severe tire and wheel damage.
■If tire inflation pressure of ea ch tire becomes low while driving
Do not continue driving, or your tires and/or wheels may be ruined.
