3547-2. Steps to take in an emergency
■The tire pressure warning light may come on due to natural causes
The tire pressure warnin g light may come on due to natural causes such as natural air leaks
and tire inflation pressure chan ges caused by temperature. In this case, adjusting the tire
inflation pressure will turn off the warning light (after a few minutes).
■Situations in which the tire pressure warning system may not function properly
P.316
■If the tire pressure warning light freque ntly comes on after blinking for 1 minute
If the tire pressure warning lig ht frequently comes on after blinking for 1 minute when the
engine switch
checked by your Lexus dealer.
■Warning buzzer
In some cases, the buzzer may not be heard du e to being in a noisy location or audio sound.
■Customization
The vehicle speed linked seat belt reminder buzzer can be disabled.
(Customizable features: P.405)
WARNING
■If both the ABS and the brake sy stem warning lights remain on
Stop your vehicle in a safe place immediately and contact your Lexus dealer. The vehicle
will become extremely unstable during brakin g, 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
When the light comes on in yellow, the assist to the power steering is restricted. When the
light comes on red, the assist to the power steering is lost and handling operations of the
steering wheel become extremely heavy. When steering wheel operations are heavier
than usual, grip the steering wheel firmly and operate it using more force than usual.
■If the tire pressure warning light comes on
Be sure to observe the following precautions. Failure to do so could cause a loss of vehi-
cle control and result in death or serious injury.
●Decelerate to the lowest appr opriate speed as soon as possible. Do not drive over 50
mph (80 km/h).
●Check and adjust the tire in flation pressure immediately.
●If the tire pressure warning lig ht comes on even after tire inflation pressure adjustment,
it is probable that you have a flat tire. Have the flat tire replaced by the nearest Lexus
dealer.
●Avoid abrupt maneuvering and braking. If th e vehicle tires deteriorate, you could lose
control of the steering wheel or the brakes.
■If a blowout or sudden air leakage should occur
The tire pressure warning system may not activate immediately.

When trouble arises
■If a message that indicates the need for the shift lever operation is shown
To prevent the shift lever from being operated incorrectly or the vehicle from moving unex-
pectedly, a message that requires shifting the shift lever may be shown on the multi-informa-
tion display. In that case, follow the instruction of the me ssage and shift the shift lever.
■If a message that indicates the malfunction of front camera is displayed
The following systems may be suspended un til the problem shown in the message is
resolved. ( P.198, 347)
●PCS (Pre-Collision System)
●LKA (Lane-Keeping Assist)
●Automatic High Beam
●Dynamic radar cruise control with full-speed range
■If “Engine Stopped Steering Power Low” (LC500) or “H ybrid System Stopped Steer-
ing Power Low” (LC500h) is shown
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 “Warming Up Maximum Vehicle Speed: 65MPH” is shown (LC500h)
The transmission is being warmed up and the ve hicle is unable to be driven over 65 mph
(110 km/h). Wait until th e transmission warms up.
■If “Stop the vehicle in a safe place Shift to P position” is shown (LC500h)
There may be a malfunction in th e hybrid system or the shift position may be shifted to N for
a long time. Immediately stop the vehicle and contact your Lexus dealer.
■If “Oil Maintenance Required Soon” is shown (LC500h)
The engine oil is scheduled to be changed. Check the engine oil, and change if necessary.
After changing the engine oil, the message should be reset. (P.295)
■If “Maintenance Required Soon” is shown
Indicates that all maintenance according to th e driven distance on the maintenance sched-
ule
* should be performed soon. The message is shown approximately 4500 miles (7200
km) after the message has been reset. If necessary, perform maintenance.
*: Refer to the separate “Sched uled Maintenance” or “Owner’s Manual Supplement” for the
maintenance interval app licable to your vehicle.
■If “Engine Oil Level Low Add or Replace” is shown
The engine oil level is low. Chec k the level of engine oil, and add if necessary. This message
may appear if the vehicle is stopped on a slope. Move the vehicle to a level surface and
check to see if the message disappears.
■If a message that indicates the need for referring to Owner’s Manual is shown
●If any of the following messages is shown on the multi-information display, follow the
instructions.
• “Engine Coolant Temp High” ( P.376, 379)
•“Battery low” ( P.369)
• “Transmission Fluid Temp High” ( P.163, 170)

WARNING
■When removing the 12-volt battery
terminals
Always remove the negative (-) terminal
first. If the positive (+) terminal contacts
any metal in the surrounding area when
the positive (+) terminal is removed, a
spark may occur, leading to a fire in addi-
tion to electrical shocks and death or
serious injury.
■Avoiding 12-volt battery fires or
explosions
Observe the following precautions to
prevent accidentally igniting the flamma-
ble gas that may be emitted from the 12-
volt battery:
A
B
C
●Make sure each jumper cable is con-
nected to the correct terminal and that
it is not unintentionally in contact with
any other than the intended terminal.
●Do not allow the other end of the
jumper cable connected to the “+” ter-
minal to come into contact with any
other parts or meta l surfaces in the
area, such as brackets or unpainted
metal.
●Do not allow the + and - clamps of the
jumper cables to come into contact
with each other.
●Do not smoke, use matches, cigarette
lighters or allow open flame near the
12-volt battery.
●If the 12-volt battery fluid level is exces-
sively low ( P.313), do not use the 12-
volt battery.
■12-volt battery precautions
The 12-volt battery contains poisonous
and corrosive acidic electrolyte, while
related parts contain lead and lead com-
pounds. Observe the following precau-
tions when handling the 12-volt battery:
●When working with the 12-volt battery,
always wear safety glasses and take
care not to allow any 12-volt battery
fluids (acid) to come into contact with
skin, clothing or the vehicle body.
●Do not lean over the 12-volt battery.
●In the event that 12-volt battery fluid
comes into contact with the skin or
eyes, immediately wash the affected
area with water and seek medical
attention.
Place a wet sponge or cloth over the
affected area until medical attention
can be received.
●Always wash your ha nds after handling
the 12-volt battery support, terminals,
and other battery-related parts.
●Do not allow children near the 12-volt
battery.
