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 vehicle
with a wheel-lift type truck from the
front, the vehicle's rear wheels and
axles must be in good conditions.

ure to do so may result in death or seri-

ous injury.

■

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.



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.

■

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.
