Maintenance and care
IS300h_EE(OM53B95E)7-2. Maintenance
Scheduled maintenance should be performed at specified intervals
according to the maintenance schedule.
For details about maintenance items and schedules, refer to the “Lexus Ser-
vice Booklet” 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 tasks require special tools and skills.
These are best performed by qualified technicians. Even if you’re an experi-
enced do-it-yourself mechanic, we recommend that repairs and maintenance
be conducted by any authorized Lexus dealer or repairer, or another duly qual-
ified and equipped professional. 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 pro-
fessional other than an authorized Lexus repairer to service or maintain your
vehicle, we recommend that you request that a record of maintenance be kept.
Maintenance requirements
To ensure safe and economical driving, day-to-day care and regular
maintenance are essential. Lexus recommends the following mainte-
nance:
Scheduled maintenance
Do-it-yourself maintenance

4347-2. Maintenance
IS300h_EE(OM53B95E)
Where to go for maintenance service?
In order to maintain your vehicle in the best possible condition, Lexus recom-
mends that maintenance service operations as well as other inspections and
repairs be carried out by authorized Lexus dealers or repairers or other duly qual-
ified and equipped professionals. For repairs and services covered by your war-
ranty, please visit an authorized Lexus dealer or repairer, who will use genuine
Lexus parts in repairing any difficulties you may encounter. There can also be
advantages in utilizing authorized Lexus dealers or repairers for non-warranty
repairs and services, as members of the Lexus network will be able to expertly
assist you with any difficulties you may encounter.
Your Lexus dealer or repairer, or another duly qualified and equipped profes-
sional will perform all of the scheduled maintenance on your vehicle reliably and
economically due to their experience with Lexus vehicles.
Does your vehicle need repairs?
Be on the alert for changes in performance and sounds, and visual tip-offs that
indicate service is needed. Some important clues are:
Engine missing, stumbling or pinging
Appreciable loss of power
Strange engine noises
A fluid leak under the vehicle (However, water dripping from the air condition-
ing system after use is normal.)
Change in exhaust sound (This may indicate a dangerous carbon monoxide
leak. Drive with the windows open and have the exhaust system checked imme-
diately.)
Flat-looking tires, excessive tire squeal when cornering, uneven tire wear
Vehicle pulls to one side when driven straight on a level road
Strange noises related to suspension movement
Loss of brake effectiveness, spongy feeling brake pedal, pedal almost touches
the floor, vehicle pulls to one side when braking
Engine coolant temperature continually higher than normal (P. 110)
If you notice any of these clues, take your vehicle to any authorized Lexus dealer
or repairer, or another duly qualified and equipped professional as soon as possi-
ble. Your vehicle may need adjustment or repair.
CAUTION
If your vehicle is not properly maintained
Improper maintenance could result in serious damage to the vehicle and possi-
ble death or serious injury.
Handling of the 12-volt battery
12-volt battery posts, terminals and related accessories contain lead and lead
compounds which are known to cause brain damage. Wash your hands after
handling.

CAUTION
Used engine oil
Used engine oil contains potentially harmful contaminants which may cause
skin disorders such as inflammation and 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
dispose of used oil and filters in household trash, in sewers or onto the
ground.
Call any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional, service station or auto parts store for information con-
cerning 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 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.

Maintenance and care

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 dealer or repairer, or another
duly qualified 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 valves and the tire pressure warn-
ing 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
transmitter may not operate properly. If a liquid sealant is used, contact any
authorized Lexus dealer or repairer, or another duly qualified and equipped
professional or other qualified service shop as soon as possible. Make sure to
replace the tire pressure warning valve and transmitter when replacing the tire.
(P. 451)
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 cush-
ioning ability of the tires. In addition, driving on rough roads may cause dam-
age to the tires themselves, as well as the vehicle’s wheels and body.
Low profile tires (except 16-inch tires)
Low profile tires may cause greater damage than usual to the tire wheel when
sustaining impact from the road surface. Therefore, pay attention to the follow-
ing:
Be sure to use proper tire inflation pressure. If tires are under-inflated, they
may be damaged more severely.
Avoid potholes, uneven pavement, curbs and other road hazards. Failure to do
so may lead to severe tire and wheel damage.
If tire inflation pressure of each tire becomes low while driving
Do not continue driving, or your tires and/or wheels may be ruined.

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 a 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.
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 any authorized Lexus
dealer or repairer, or another duly qualified and equipped professional or
other qualified service shop. In addition, make sure to purchase your tire pres-
sure warning valves and transmitters at any authorized Lexus dealer or
repairer, or another duly qualified and equipped professional.
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.
