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.

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.

■Front air conditioning filter
Set the air conditioning system to recirculated air mode. ( P. 428)
The air conditioning filter case cannot be removed with the system in outside
air mode.
Turn the engine switch off.
Open the glove box. Remove the partition. ( P. 453)
Remove the filter cover.
Remove the filter case.

Remove the air conditioning
filter from the filter case and
replace it with a new one.
The “ UP” marks shown on the fil-
ter and the filter case should be
pointing up.
Reset the air conditioning filter maintenance data. ( P. 574)
■Rear air conditioning filter (if equipped)
Turn the engine switch off.
Open the trunk lid. Remove
the filter cover.
Remove the air conditioning
filter and replace it with a new
one.
The “ UP” mark shown on the filter
should be pointing up.

■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)
Filters are installed in the seats. When it is necessary to clean or replace the filters,
contact your Lexus dealer.

■When the tire pressure warning light comes on (vehicles with the tire pressure
warning system)
Carry out the following procedure after the tire temperature has lowered sufficiently.
●Check the tire inflation pressure and adjust it to the appropriate level.
●If the warning light does not go out after several minutes, check that the tire infla-
tion pressure is at the specified level and carry out initialization.
The warning light may come on again if the above operations are conducted without
first allowing the tire temperature to lower sufficiently.
■The tire pressure warning light may come on due to natural causes (vehicles with
the tire pressure warning system)
The tire pressure warning light may come on due to natural causes such as natural
air leaks and tire inflation pressure changes caused by temperature. In this case,
adjusting the tire inflation pressure will turn off the warning light (after a few minutes).
■When a tire is replaced with a spare tire (vehicles with the tire pressure warning
system)
The spare tire is also equipped with a tire pressure warning valve and transmitter. The
tire pressure warning light will turn on if the tire inflation pressure of the spare tire is
low. If a tire goes flat, the tire pressure warning light will not turn off even though the
flat tire has been replaced with the spare tire.
■Conditions that the tire pressure warning system may not function properly (vehi-
cles with the tire pressure warning system)
P. 561
■If the tire pressure warning light frequently comes on after blinking for 1 minute
(vehicles with the tire pressure warning system)
If the tire pressure warning light frequently comes on after blinking for 1 minute when
the engine switch is turned to IGNITION ON mode, have it checked by your Lexus
dealer.
■Warning buzzer
In some cases, the buzzer may not be heard due to ambient noise or sounds from the
audio system.
■Customization (for GCC countries* and Yemen)
The vehicle speed linked seat belt reminder buzzer can be disabled.
