

Remove the seat belt first.



If the door can be opened, open the 
door and exit the vehicle.



If the door can not be opened, open 
the window using the power window 
switch and exit the vehicle through 
the window.



If the window can not be opened 
using the power window switch, 
remain calm, wait until the water 
level inside the vehicle rises to the 
point that the water pressure inside 
of the vehicle equals the water pres-
sure outside of the vehicle, and then 
open the door and exit the vehicle.

If the vehicle is trapped in 
rising water

In the event the vehicle is sub-
merged in water, remain calm and

WARNING

Q

Using an emergency hammer

*

 for 

emergency escape

The front side windows and rear side 

windows, as well as the rear window can 
be shattered by an emergency hammer

*

 

used for emergency escape.
However, an emergency hammer can 

not shatter the windshield as it is lami-

nated glass.

*

: Contact any authorized Lexus retailer 

or Lexus authorized repairer, or any 
reliable repairer, or aftermarket acces-
sory manufacturer for further informa-
tion about an emergency hammer.

Q

Escaping the vehicle from the window

There are cases where escaping the 

vehicle from the window is not possible 

due to seating position, passenger body 

type, etc.
When using an emergency hammer, 

consider your seat location and the size 

of the window opening to ensure that the 

opening is accessible and large enough 

to escape.

7-2.Steps to take in an emergency

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.

Q

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.

Q

While towing

O

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.

O

Do not turn the engine switch <power 

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.

Q

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.

436

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 any authorized Lexus 
retailer or Lexus authorized repairer, 
or any reliable repairer or commercial 
towing service.



There is a malfunction in the shift 
control system. (



The 12-volt battery is discharged. 
(

P.465)

The following may indicate a problem 
with your transmission. Contact any 
authorized Lexus retailer or Lexus 
authorized repairer, or any reliable 
repairer 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.



From the front

Use a towing dolly under the rear 
wheels.

NOTICE

Q

To prevent damage to the vehicle 

when towing using a wheel-lift type 

truck

O

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.

O

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.

Q

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.

Q

To prevent damage to the vehicle 

during emergency towing

Do not secure cables or chains to the 

suspension components.



From the rear

Use a towing dolly under the front 
wheels.

When using a flat-bed truck to trans-
port the vehicle, use tire strapping 
belts. Refer to the owner’s manual of 
the flat-bed truck for the tire strapping 
method.
In order to suppress vehicle movement 
during transportation, set the parking 
brake and turn the engine switch 
<power switch> off.

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 30 km/h (18 mph).
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.

To have your vehicle towed by another 
vehicle, the towing eyelet must be 
installed to your vehicle. Install the tow-
ing eyelet using the following proce-
dure.

1

Take out the screwdriver and the 
towing eyelet. (



P.412)

2

Remove the eyelet cover using a 
flathead screwdriver.

To protect the bodywork, place a rag 

between the screwdriver and the vehicle 

body as shown in the illustration.

Q

The tire pressure warning light may come on due to natural causes

The tire pressure warning light may come on due to natural causes such as natural air leaks 

and tire inflation pressure changes caused by temperature. In this case, adjusting the tire 

inflation pressure will turn off the warning light (after a few minutes).

Q

If the tire pressure warning light frequently comes on after blinking for 1 minute

If the tire pressure warning light frequently comes on after blinking for 1 minute when the 

engine switch <power switch> is turned to IGNITION ON mode <ON mode>, have it 

checked by any authorized Lexus retailer or Lexus authorized repairer, or any reliable 

repairer.

Q

Warning buzzer

In some cases, the buzzer may not be heard due to being in a noisy location or audio sound.

WARNING

Q

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 reliable 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.

Q

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 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.

Q

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.

O

Decelerate to the lowest appropriate speed as soon as possible. Do not drive over 80 

km/h (50 mph).

O

Check and adjust the tire inflation pressure immediately.

O

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 nearest authorized 

Lexus retailer or Lexus authorized repairer, or any reliable repairer.

O

Avoid abrupt maneuvering and braking. If the vehicle tires deteriorate, you could lose 

control of the steering wheel or the brakes.

Q

If a blowout or sudden air leakage should occur

The tire pressure warning system may not activate immediately.
