7-2. Steps to take in an emergency
In the following situations, it is not pos-
sible to be towed by another vehicle
using cables or chains, as the rear
wheels may be locked due to the park-
ing lock. Contact your Lexus dealer or
commercial towing service.
There is a malfunction in the shift
control system. (
There is a malfunction in the engine
immobilizer system <immobilizer
system>. (
There is a malfunction in the smart
access system with push-button
start. (
The 12-volt battery is discharged.
(
The following may indicate a problem
with your transmission. Contact your
Lexus dealer or commercial towing
service before towing.
LC500: The engine is running but
the vehicle does not move.
LC500h: The hybrid system warn-
ing message is shown on the multi-
information display and the vehicle
does not move.
The vehicle makes an abnormal
sound.
Do not tow with a sling-type truck to
prevent body damage.
WARNING
■
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.
NOTICE
■
To prevent damage to the vehicle
when towing using a wheel-lift type
truck
●
Do not tow the vehicle from the rear
when the engine switch <power
switch> is off. The steering lock mecha-
nism is not strong enough to hold the
front wheels straight.
●
When raising the vehicle, ensure ade-
quate ground clearance for towing at
the opposite end of the raised vehicle.
Without adequate clearance, the vehi-
cle could be damaged while being
towed.
■
To prevent damage to the vehicle
when towing with a sling-type truck
Do not tow with a sling-type truck, either
from the front or rear.
■
To prevent damage to the vehicle
during emergency towing
Do not secure cables or chains to the
suspension components.

From the front
Use a towing dolly under the rear
wheels.
From the rear
Use a towing dolly under the front
wheels.
If your vehicle is transported by a flat-
bed truck, it should be tied down at the
locations shown in the illustration.
If you use chains or cables to tie down
your vehicle, the angles shaded in
black must be 45°.
Do not overly tighten the tie downs or
the vehicle may be damaged.
If a tow truck is not available in an
emergency, your vehicle may be tem-
porarily towed using cables or chains
secured to the emergency towing eye-
lets. This should only be attempted on
hard surfaced roads for short distances
at under 18 mph (30 km/h).
A driver must be in the vehicle to steer
and operate the brakes. The vehicle’s
wheels, drive train, axles, steering and
brakes must be in good condition.

WARNING
■
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
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 appropriate speed as soon as possible. Do not drive over 50
mph (80 km/h).
●
Check and adjust the tire inflation pressure immediately.
●
If the tire pressure warning light 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 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.

WARNING
■
Maintenance of the tires
Each tire, including the spare (if provided), should be checked monthly when cold and
inflated to the inflation pressure recommended by the vehicle manufacturer on the vehi-
cle placard or tire inflation pressure label (tire and load information label). (If your vehicle
has tires of a different size than the size indicated on the vehicle placard or tire inflation
pressure label [tire and load information label], you should determine the proper tire
inflation pressure for those tires.)
As an added safety feature, your vehicle has been equipped with a tire pressure monitor-
ing system (TPMS-tire pressure warning system) that illuminates a low tire pressure tell-
tale (tire pressure warning light) when one or more of your tires is significantly under-
inflated. Accordingly, when the low tire pressure telltale (tire pressure warning light) illu-
minates, you should stop and check your tires as soon as possible, and inflate them to the
proper pressure. Driving on a significantly under-inflated tire causes the tire to overheat
and can lead to tire failure. Under-inflation also reduces fuel efficiency and tire tread life,
and may affect the vehicle’s handling and stopping ability.
Please note that the TPMS (tire pressure warning system) is not a substitute for proper
tire maintenance, and it is the driver’s responsibility to maintain correct tire pressure, even
if under-inflation has not reached the level to trigger illumination of the TPMS low tire
pressure telltale (tire pressure warning light).
Your vehicle has also been equipped with a TPMS (tire pressure warning system) mal-
function indicator to indicate when the system is not operating properly. The TPMS (tire
pressure warning system) malfunction indicator is combined with the low tire pressure
telltale (tire pressure warning light). When the system detects a malfunction, the telltale
will flash for approximately one minute and then remain continuously illuminated. This
sequence will continue upon subsequent vehicle start-ups as long as the malfunction
exists. When the malfunction indicator is illuminated, the system may not be able to
detect or signal low tire pressure as intended.
TPMS (tire pressure warning system) malfunctions may occur for a variety of reasons,
including the installation of replacement or alternate tires or wheels on the vehicle that
prevent the TPMS (tire pressure warning system) from functioning properly. Always
check the TPMS (tire pressure warning system) malfunction telltale after replacing one or
more tires or wheels on your vehicle to ensure that the replacement or alternate tires and
wheels allow the TPMS (tire pressure warning system) to continue to function properly.

system may not operate properly.
