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

Be sure to transport the vehicle with all

four wheels raised off the ground. If the

vehicle is towed with the tires contacting

the ground, the drivetrain and related

parts may be damaged or an accident

may occur due to a change in direction

of the vehicle.

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 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.

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 is OFF. The

steering lock mechanism 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.

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

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.

installed to your vehicle. Install the tow-
ing eyelet using the following proce-
dure.
