rising water to enter the vehicle, and
exit the vehicle. When the outside
water level exceeds half the height
of the door, the door cannot be
opened from the inside due to water
pressure.

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.

2WD models: If towing your vehi-
cle with a wheel-lift type truck from
the front, the vehicle’s rear wheels
and axles must be in good condi-
tions. (



P.407, 408) If they are

damaged, use a towing dolly or flat-
bed truck.

AWD models: If towing your vehi-
cle with a wheel-lift type truck, use
a towing dolly. (



P.407, 408)

WARNING

Observe the following precautions.

Failure to do so may result in death or

serious injury.

Q

When towing the vehicle



2WD models

Be sure to transport the vehicle with the

front wheels raised or with all four wheels

raised off the ground. If the vehicle is

towed with the front wheels contacting

the ground, the drivetrain and related

parts may be damaged or electricity

generated by the operation of the motor

may cause a fire to occur depending on

the nature of the damage or malfunction.



AWD models

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 or related

parts may be damaged, the vehicle may

fly off the truck, or electricity generated

by the operation of the motor may cause

a fire to occur depending on the nature

of the damage or malfunction.

WARNING

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 power switch off.

There is a possibility that the steering

wheel is locked and cannot be oper-

ated.

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 power 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
