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

Except F SPORT models: Take out 
the towing eyelet. (



P.570, 580)

F SPORT models: Take out the 
flathead screwdriver and towing 
eyelet. (



P.570, 580)

7-2. Steps to take in an emergency

4

Tighten down the towing eyelet 
securely using a wheel bolt wrench 
or hard metal bar.

5

Securely attach cables or chains to 
the towing eyelet.

Take care not to damage the vehicle body.

6

Enter the vehicle being towed and 
start the hybrid system.

If the hybrid system does not start, turn the 

power switch to ON.

7

Shift the shift position to N and 
release the parking brake.

Turn automatic mode off. (



P.246)

■

While towing

If the hybrid system is off, the power assist 

for the brakes and steering will not function, 

making steering and braking more difficult.

■

Wheel bolt wrench

Vehicles with a spare tire: Wheel bolt 

wrench is installed in luggage compart-

ment. (



P.580)

Vehicles with an emergency tire puncture 

repair kit: Wheel bolt wrench can be pur-

chased at any authorized Lexus retailer or 

Lexus authorized repairer, or any reliable 

repairer.

WARNING

Observe the following precautions. Fail-

ure to do so may result in death or seri-

ous injury.

■

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 perform any of the following as 

doing so may cause the parking lock 

mechanism to engage, locking the 

front wheels and possibly leading to an 

accident resulting in death or serious 

injury:

• Unfasten the driver’s seat belt and 

open the driver’s door.

• Turn the power switch off.

■

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

WARNING

■

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.

■

If the tire pressure warning light 

comes on

Be sure to observe the following precau-

tions.

Failure to do so could cause a loss of 

vehicle control and result in death or 

serious injury.

●

Stop your vehicle in a safe place as 

soon as possible. Adjust the tire infla-

tion pressure immediately.

●

Vehicles with a spare tire: If the tire 

pressure warning light comes on even 

after tire inflation pressure adjustment, 

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 any authorized 

Lexus retailer or Lexus authorized 

repairer, or any reliable repairer.

●

Vehicles with an emergency tire punc-

ture repair kit: If the tire pressure warn-

ing light comes on even after tire 

inflation pressure adjustment, it is 

probable that you have a flat tire. 

Check the tires. If a tire is flat, repair 

the flat tire by using emergency tire 

puncture repair kit.

●

Avoid abrupt maneuvering and brak-

ing.

If the vehicle tires deteriorate, you 

could lose control of the steering 

wheel or the brakes.

A puncture caused by a nail or 
screw passing through the tire 
tread can be repaired temporarily

WARNING

■

If you have a flat tire

Do not continue driving with a flat tire.

Driving even a short distance with a flat 

tire can damage the tire and the wheel 

beyond repair.

Driving with a flat tire may cause a cir-

Emergency tire puncture repair kit

●

The sealant stored in the emergency tire 

puncture repair kit can be used only once 

to temporarily repair a single tire. If the 

sealant in the bottle and other parts of the 

kit have been used and need to be 

replaced, contact any authorized Lexus 

retailer or Lexus authorized repairer, or 

any reliable repairer.

●

The compressor can be used repeatedly.

●

The sealant can be used when the outside 

temperature is from -30°C (-22°F) to 

60°C (140°F).

●

The kit is exclusively designed for size 

and type of tires originally installed on 

your vehicle. Do not use it for tires that a 

different size than the original ones, or for 

any other purposes.

●

If the sealant gets on your clothes, it may 

stain.

●

If the sealant adheres to a wheel or the 

surface of the vehicle body, the stain may 

not be removable if it is not cleaned at 

once. Immediately wipe away the sealant 

with a wet cloth.

●

During operation of the kit, a loud opera-

tion noise is produced. This does not indi-

cate a malfunction.

●

Do not use the emergency tire puncture 

repair kit to check or adjust the tire infla-

tion pressure.

■

Note for checking the emergency tire 

puncture repair kit

●

Check the sealant expiry date occasion-

ally. The expiry date is shown on the bot-

tle.

●

Do not use sealant whose expiry date has 

already passed. Otherwise, repairs con-

ducted using the emergency tire punc-

ture repair kit may not be performed 

properly.

●

Replace the liquid sealant bottle of the 

emergency tire puncture repair kit before 

it’s expiration date. For information on 

replacement, contact any authorized
