CAUTION
■For your safety
●Please drive safely.
The function of this system is to assist you in making the Emergency Call in case
of accidents as traffic accidents or sudden medical emergencies, and it does not
protect the driver or the passengers in any way. Please drive safely and fasten
your seatbelts at all times for your safety.
●In case of an emergency, make lives the top priority.
●If you smell anything burning or another unusual smell, do not stay inside the vehi-
cle and evacuate to a safe area immediately.
●Since the system detects shocks, the automatic reporting may not always occur
synchronized with the operation of the airbag system. (If the vehicle is bumped
from behind, etc.)
●The airbag may not inflate even in case of an accident, if it does not involve high
impact. In such cases, the system may not make emergency calls automatically.
The system may also not make automatic emergency calls even if the airbag has
been inflated. If any of these should occur, please report to the Public Safety
Answering Point (PSAP) by operating the “SOS” button panel button.
●For safety, do not make the Emergency Call while driving.
Making calls during driving may cause mishandling of the steering wheel, which
may lead to unexpected accidents.
Stop the vehicle and confirm the safety of the area before making the Emergency
Call.
●When changing fuses, please use fuses that correspond to the described stan-
dard. If you use fuses other than those de scribed, it may cause ignition or smoke
in the circuit and may lead to a fire.
●Using the system while there is smoke or an unusual smell may cause a fire. Stop
using the system immediately and consult your Lexus dealer.

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.

■How to initialize the tire pressure warning system
Park the vehicle in a safe place and turn the engine switch off.
Initialization cannot be performed while the vehicle is moving.
Adjust the tire inflation pressure to the specified cold tire inflation
pressure level. ( P. 660, 662)
Make sure to adjust the tire pressure to the specified cold tire inflation pres-
sure level. The tire pressure warning system will operate based on this pressure
level.
Turn the engine switch to IGNITION ON mode.
Press and hold the tire pres-
sure warning reset switch until
the tire pressure warning light
blinks slowly 3 times.
Wait for a few minutes with the engine switch in IGNITION ON
mode and then turn the engine switch off.

◆Registering ID codes
The tire pressure warning valve and transmitter is equipped with a
unique ID code. When replacing a tire pressure warning valve and
transmitter, it is necessary to register the ID code. Have the ID code
registered by your Lexus dealer.
■When to replace your vehicle’s tires
Tires should be replaced if:
●The treadwear indicators are showing on a tire.
●You have tire damage such as cuts, splits, cracks deep enough to expose the fabric,
and bulges indicating internal damage
●A tire goes flat repeatedly or cannot be properly repaired due to the size or loca-
tion of a cut or other damage
If you are not sure, consult with your Lexus dealer.
■Replacing tires and wheels (vehicles with the tire pressure warning system)
If the ID code of the tire pressure warning valve and transmitter is not registered, the
tire pressure warning system will not work properly. After driving for about 10 min-
utes, the tire pressure warning light blinks for 1 minute and stays on to indicate a sys-
tem malfunction.
■Tire life
Any tire over 6 years old must be checked by a qualified technician even if it has sel-
dom or never been used or damage is not obvious.
■Routine tire inflation pressure checks (vehicles with the tire pressure warning sys-
tem)
The tire pressure warning system does not replace routine tire inflation pressure
checks. Make sure to check tire inflation pressure as part of your routine of daily
vehicle checks.
■When rotating the tires (vehicles with the tire pressure warning system)
Make sure that the engine switch is off. If the tires are rotated while the engine switch
is in IGNITION ON mode, the tire position information will not be updated.
If this accidentally occurs, either turn the engine switch to off and then to IGNITION
ON mode, or initialize the system after checking that the tire pressure is properly
adjusted.

LS460/LS460L_GE (OM50G06E)
■The initialization operation (vehicles with the tire pressure warning system)
●Make sure to carry out initialization after adjusting the tire inflation pressure.
Also, make sure the tires are cold before carrying out initialization or tire inflation
pressure adjustment.
●If you have accidentally turned the engine switch off during initialization, it is not
necessary to press the reset switch again as initialization will restart automatically
when the engine switch has been turned to IGNITION ON mode for the next time.
●If you accidentally press the reset switch when initialization is not necessary, adjust
the tire inflation pressure to the specified level when the tires are cold, and conduct
initialization again.
■Warning performance of the tire pressure warning system (if equipped)
The warning of the tire pressure warning system will change in accordance with driv-
ing conditions. For this reason, the system may give a warning even if the tire pres-
sure does not reach a low enough level, or if the pressure is higher than the pressure
that was adjusted to when the system was initialized.
■When initialization of the tire pressure warning system has failed (vehicles with the
tire pressure warning system)
Initialization can be completed in a few minutes. However, in the following cases, the
settings have not been recorded and the system will not operate properly. If
repeated attempts to record tire inflation pressure settings are unsuccessful, have
the vehicle inspected by your Lexus dealer.
●When operating the tire pressure warning reset switch, the tire pressure warning
light does not blink 3 times.
●After carrying out the initialization procedure, the tire pressure warning light blinks
for 1 minute then stays on after driving for 20 minutes.

■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.
