What about do-it-yourself maintenance?
Many of the maintenance items are easy to do yourself if you have a little mechan-
ical ability and a few basic automotive tools. Simple instructions for how to per-
form them are presented in this section.
Note, however, that some maintenance tasks require special tools and skills.
These are best performed by qualified technicians. Even if you are an experi-
enced do-it-yourself mechanic, we recommend that repairs and maintenance be
conducted by your Lexus dealer who will keep a record of maintenance on your
vehicle. This record could be helpful should you ever require Warranty Service.
■Does your vehicle need repairs?
Be on the alert for changes in performance and sounds, and visual tip-offs that indi-
cate 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 conditioning
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 immediately.)
●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. 125)
If you notice any of these clues, take your vehicle to your Lexus dealer as soon as
possible. Your vehicle may need adjustment or repair.

Scheduled maintenance
Perform maintenance by the schedule as follows:
Maintenance schedule requirements
Your vehicle needs to be serviced according to the normal
maintenance schedule. (See “Maintenance schedule”.)
If you mainly operate your vehicle under one or more of the special
operating conditions below, some of the maintenance schedule items
need to be serviced more frequently in order to keep your vehicle in
good condition. (See “Additional maintenance schedule”.)
A. Road Conditions
1. Operating on rough or muddy
roads, or roads with melted
snow
2. Operating on dusty roads
(Roads in areas where their
pavement rate is low, or a
cloud of dust often arises and
the air is dry)
B. Driving Conditions
1. Heavily loaded vehicle (For
example, using a car top car-
rier and so forth.)
2. Repeated short trips less than
8 km (5 miles) and outside
temperatures remain below
freezing (Engine temperature
will not reach to normal tem-
perature)
3. Extensive idling and/or low
speed driving for a long dis-
tance such as police, taxi or
door-to-door delivery use
4. Continuous high speed driving
(80% or more of maximum
vehicle speed) for over 2 hours

Tire inflation pressure (P. 568)• Tire pressure gauge
• Compressed air source
Washer fluid ( P. 553)
• Water or washer fluid containing anti-
freeze (for winter use)
• Funnel (used only for adding water or
washer fluid)
CAUTION
The engine compartment contains many mechanisms and fluids that may move sud-
denly, become hot, or become electrically energized. To avoid death or serious
injury, observe the following precautions.
■When working on the engine compartment
●Keep hands, clothing and tools away from the moving fan and engine drive belt.
●Be careful not to touch the engine, radiator, exhaust manifold, etc. right after driv-
ing as they may be hot. Oil and other fluids may also be hot.
●Do not leave anything that may burn easily, such as paper and rags, in the engine
compartment.
●Do not smoke, cause sparks or expose an open flame to fuel or the battery. Fuel
and battery fumes are flammable.
●Be extremely cautious when working on the battery. It contains poisonous and
corrosive sulfuric acid.
●Take care because brake fluid can harm your hands or eyes and damage painted
surfaces. If fluid gets on your hands or in your eyes, flush the affected area with
clean water immediately.
If you still experience disc omfort, consult a doctor.
■When working near the electric cooling fans or radiator grille
Be sure the engine switch is off.
With the engine switch in IGNITION ON mode, the electric cooling fans may
automatically start to run if the air conditioning is on and/or the coolant tempera-
ture is high. ( P. 549)
■Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from get-
ting in your eyes.

Maintenance and care
LS460/LS460L_GE (OM50G06E)
NOTICE
■Repairing or replacing tires, wheels, tire pressure warning valves, transmitters
and tire valve caps (vehicles with the tire pressure warning system)
●When removing or fitting the wheels, tires or the tire pressure warning valves and
transmitters, contact your Lexus dealer 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 warning
valves could be bound.
●When replacing tire valve caps, do not use tire valve caps other than those speci-
fied. The cap may become stuck.
■To avoid damage to the tire pressure wa rning valves and transmitters (vehicles
with the tire pressure warning system)
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 your Lexus
dealer 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. 558)
■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 pressure of each tire becomes low while driving
Do not continue driving, or your tires and/or wheels may be ruined.

Maintenance and care
LS460/LS460L_GE (OM50G06E)
CAUTION
■Proper inflation is critical to save tire performance
Keep your tires properly inflated.
If the tires are not properly inflated, the following conditions may occur which
could lead to an accident resulting in death or serious injury:
●Excessive wear
●Uneven wear
●Poor handling
●Possibility of blowouts resulting from overheated tires
●Air leaking from between tire and wheel
●Wheel deformation and/or tire damage
●Greater possibility of tire damage while driving (due to road hazards, expansion
joints, sharp edges in the road, etc.)
NOTICE
■When inspecting and adjusting tire inflation pressure
Be sure to put the tire valve caps back on.
If a valve cap is not installed, dirt or moisture may get into the valve and cause an air
leak, resulting in decreased tire inflation pressure.

■Checking interval
Front air conditioning filter
Inspect and replace the air conditioning filter when a message is appeared on the
multi-information display. In dusty areas or areas with heavy traffic flow, early
replacement may be required.
Rear air conditioning filter (if equipped)
Replace every 15000 km (9000 miles).
■If air flow from the vents decreases dramatically
The filter may be clogged. Check the filter and replace if necessary.
■After changing the front air conditioning filter
The front air conditioning filter maintenance data should be reset. Perform the fol-
lowing procedures:
Turn the engine switch to IGNITION ON mode.
Press and hold (on the air conditioning panel) for 4 seconds or more.
A buzzer will sound to indicate that the maintenance data has been successfully
reset.
■Rear air conditioning filter (if equipped)
If it is necessary to clean or replace the filter, contact your Lexus dealer.
■Climate control seat filter (if equipped)
