5586-3. Do-it-yourself maintenance
LS460/LS460L_GE (OM50G06E)
Your vehicle is equipped with a tire pressure warning system that uses tire
pressure warning valves and transmitters to detect low tire inflation pres-
sure before serious problems arise.
●If the tire pressure drops below a predetermined level, the driver is
warned by a screen display and a warning light. ( P. 609, 614)
◆Installing tire pressure wa rning valves and transmitters
When replacing tires or wheels, tire pressure warning valves and trans-
mitters must also be installed.
When new tire pressure warning valves and transmitters are installed,
new ID codes must be registered in the tire pressure warning computer
and the tire pressure warning system must be initialized. Have tire pres-
sure warning valve and transmitter ID codes registered by your Lexus
dealer. ( P. 560)
◆Initializing the tire pressure warning system
■The tire pressure warning system must be initialized in the following
circumstances:
●When rotating the tires.
●When the tire inflation pressure is changed such as when changing
traveling speed. ( P. 660, 662)
●When changing the tire size.
When the tire pressure warning system is initialized, the current tire
inflation pressure is set as the benchmark pressure.
Tire pressure warning system (if equipped)
●The tire pressure detected by the tire pressure
warning system can be displayed on the multi-
information display. ( P. 133)

■While towing
If the engine is not running, the power assist for the brakes and steering will not func-
tion, making steering and braking more difficult.
■Wheel nut wrench
Wheel nut wrench is installed in trunk. ( P. 619)
CAUTION
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When towing the vehicle
2WD models
Be sure to transport the vehicle with all four
wheels raised off the ground. If the vehicle is
towed with the tires contacting the ground,
the drivetrain and related parts may be dam-
aged or an accident may occur due to a
change in direction of the vehicle.

When trouble arises
LS460/LS460L_GE (OM50G06E)
CAUTION
■If both the ABS and the brake system warning lights remain on
Stop your vehicle in a safe place immediately and contact your Lexus dealer. The
vehicle will become extremely unstable during braking, and the ABS system may
fail, which could cause an accident resulting in death or serious injury.
■When the electric power steering system warning light comes on
The steering wheel may become extremely heavy.
If the steering wheel becomes heavier than usual when operating, hold firmly and
operate using more force than usual.
■If the tire pressure warning light comes on (vehicles with the tire pressure warn-
ing system)
Be sure to observe the following precautions. Failure to do so could cause a loss of
vehicle control and result in death or serious injury.
●As the tire inflation pressure may be low when this warning light is illuminated,
stop your vehicle in a safe place as soon as possible and adjust the tire inflation
pressure immediately.
●If the tire pressure warning light comes on even after tire inflation pressure adjust-
ment, it is probable that you have a flat tire. Check the tires. If a tire is flat, change
it with the spare tire and have the flat tire repaired by the nearest Lexus dealer.
●Avoid abrupt maneuvering and braking. If the vehicle tires deteriorate, you could
lose control of the steering wheel or the brakes.
■If a blowout or sudden air leakage should occur (vehicles with the tire pressure
warning system)
The tire pressure warning system may not activate immediately.
NOTICE
■To ensure the tire pressure warning system operates properly (vehicles with the
tire pressure warning system)
Do not install tires with different specifications or makers, as the tire pressure warn-
ing system may not operate properly.

■Warning message in radar cruise mode (if equipped)
In the following cases, the warning message may not be displayed even if vehicle-to-
vehicle distance decreases:
●When your vehicle and the vehicle ahead are traveling at the same speed or the
vehicle ahead is traveling more quickly than your vehicle
●When the vehicle ahead is traveling at a very low speed
●Immediately after cruise control speed is set
●At the instant the accelerator pedal is depressed
■The LKA (Lane-Keeping Assist) lane de parture warning function (if equipped)
In the following cases, the warning message will not be displayed even if a lane line is
crossed.
●When the vehicle speed deviates from the operating range of the LKA system
functions
●When the lane lines cannot be recognized
●When the steering wheel is turned as far as necessary to cause the vehicle to
change lanes
■System warning lights
The master warning light does not come on or flash in the following cases. Instead, a
separate system warning light will come on or flash along with the message shown
on the multi-information display.
●Malfunction of the brake system
The brake system warning light (red indicator) comes on. ( P. 605)
●Malfunction of the electronically controlled brake system or electric parking brake
The brake system warning light (yellow indicator) comes on. ( P. 607)
●Malfunction of the ABS
The ABS warning light comes on. ( P. 606)
●Malfunction of the charging system
The charging system warning light comes on. ( P. 606)
●Indicates that a door or the trunk is not fully closed
The open door warning light comes on. ( P. 608)
●High engine coolant temperature
The needle of the engine coolant temperature gauge enters the red zone.
