If your vehicle needs to be
towed
If towing is necessary, we recom-
mend having your vehicle towed by
any authorized Lexus retailer or
Lexus authorized repairer, or any
reliable repairer or commercial
towing service, using a wheel-lift
type truck or flatbed truck.
Use a safety chain system for all
towing, and abide by all state/pro-
vincial and local laws.
WARNING
Observe the following precautions. Failure to do so may result in death or
serious injury.
■When towing the vehicle
LC500: Be sure to transport the vehicle with all four wheels raised off the ground. If the vehicle is towed with the tires con-
tacting the ground, the drivetrain and related parts may be damaged or an accident may occur due to a change in
direction of the vehicle.
LC500h: Be sure to transport the vehi- cle with all four wheels raised off the
ground. If the vehicle is towed with the tires contacting the ground, the drive-train and related parts may be damaged,
an accident may occur due to a change in direction of the vehicle or electricity generated by the operation of the motor
may cause a fire to occur depending on the nature of the damage or malfunction.
■While towing
●When towing using cables or chains, avoid sudden starts, etc. which place excessive stress on the towing eyelets,
cables or chains. The towing eyelets, cables or chains may become dam-aged, broken debris may hit people,
and cause serious damage.
●Do not turn the engine switch off.This may lead to an accident as the
rear wheels will be locked by the park- ing lock. Also, there is a possibility that the steering wheel is locked and can-
not be operated.
■Installing towing eyelets to the vehi- cle
Make sure that towing eyelets are installed securely.
If not securely installed, towing eyelets may come loose during towing.

7-2. Steps to take in an emergency
■Conditions that the tire pressure warning system may not function properly
 P.330
■If the tire pressure warning light frequently 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 is turned to IGNITION ON mode , have it
checked by any authorized Lexus retailer or Lexus authorized repairer, or any reliable repairer.
■Warning buzzer
In some cases, the buzzer may not be heard due to being in a noisy location or audio sound.
WARNING
■If both the ABS and the brake system warning lights remain on
Stop your vehicle in a safe place immediately and contact any authorized Lexus retailer
or Lexus authorized repairer, or any reliabl e repairer. 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
When the light comes on yellow, the assist to the power steering is restricted. When the
light comes on red, the assist to the power st eering 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 appropriate speed as soon as possible. Do not drive over 80 km/h (50 mph).
●Check and adjust the tire inflation pressure immediately.
●If the tire pressure warning light comes on ev en after tire inflation pressure adjustment, it is probable that you have a flat tire. Have the flat tire replaced by nearest authorized
Lexus retailer or Lexus authorized repairer, or any reliable repairer.
●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
The tire pressure warning system may not activate immediately.

7-2. Steps to take in an emergency
Take your vehicle to the nearest autho-
rized Lexus retailer or Lexus autho-
rized repairer, or any reliable repairer,
or authorized tire dealer as soon as
possible if any tire goes flat.
The vehicle can be driven for a maximum
of 160 km (100 miles) at a speed below 80
km/h (50 mph) after the tire pressure
warning light comes on. ( P.374)
A run-flat tire has a mark on the
side wall.
■In some condition (such as at high tem-
peratures)
You cannot continue driving for up to 160 km (100 miles).
■For the detailed information on run-flat tires
See the tire warranty booklet.
If you have a flat tire
Your vehicle is not equipped with a
spare tire, but instead you can con-
tinue driving the vehicle with run-
flat tires even if any tire goes flat.
In this case, slow down and drive
with extra caution.

■When replacing the tires
When removing or fitting the wheels, tires or the tire pressure warning valve and transmitter, contact any authorized
Lexus retailer or Lexus authorized repairer, or any reliable repairer as the tire pressure warning valve and transmit-
ter may be damaged if not handled cor- rectly.
■When driving over bumps
If a vehicle has a flat tire, the vehicle height will be lower than usual. Ensure
that nothing strikes the bottom of the vehicle.
■To avoid damaging the tire pressure warning valves and transmitters
When a tire is repaired with liquid seal-
ants, the tire pressure warning valve and transmitter may not operate properly. If a liquid sealant is used, contact any autho-
rized Lexus retailer or Lexus authorized repairer, or any reliable repairer or other qualified service shop as soon as possi-
ble. Make sure to replace the tire pres- sure warning valve and transmitter when replacing the tire. ( P.335)
