IF YOUR VEHICLE NEEDS TO BETOWED
If towing is necessary, we recommend you to have it done
by your Lexus dealer or a commercial tow truck service.
In consultation with them, have your vehicle towed using
either (a) or (b).
(a) Towing with a wheel lift type truck
(b) Using a flat bed truck
(c) Never tow with a sling type truck
Only when you cannot receive a towing service from a
Lexus dealer or commercial tow truck service, tow your
vehicle carefully in accordance with the instructions
given in ª(d) Emergency towingº on page 522.
Proper equipment will help ensure that your vehicle is not
damaged while being towed. Commercial operators are
generally aware of the state/provincial and local laws
pertaining to towing.
Your vehicle can be damaged if it is towed incorrectly. Although
most operators know the correct procedure, it is possible to
make a mistake. To avoid damage to your vehicle, make sure
the following precautions are observed. If necessary, show
this page to the tow truck driver. TOWING PRECAUTIONS:
Use a safety chain system for all towing, and abide by the
state/provincial and local laws. The wheels and axle on the
ground must be in good condition. If they are damaged, use
a towing dolly.
CAUTION
When
your vehicle is towed, put the vehicle height in the
ªNº (normal) mode and push the ªHEIGHT CONTROL
OFFº switch to turn off the rear height control air
suspension. Otherwise, the vehicle height may be
changed in the automatic leveling function, resulting in
accident. For details, see ªRear height control air
suspensionº on page 422.

REPLACING WHEELS
When to replace your wheels
If you have wheel damage such as bending, cracks or
heavy corrosion, the wheel should be replaced.
If you fail to replace a damaged wheel, the tire may slip off the
wheel or cause loss of handling control.
Replacement with used wheels is not recommended as they
may have been subjected to rough treatment or high mileage
and could fail without warning. Also, bent wheels which have
been straightened may have hidden structural damage and
therefore should not be used. Never use an inner tube in a
leaking wheel which is designed for a tubeless tire.
Wheel selection
When replacing wheels, care should be taken to ensure
that they are equivalent to those removed in load capacity,
diameter, rim width, and offset.
Correct replacement wheels are available at your Lexus
dealer.
A wheel of a different size or type may adversely affect
handling, wheel and bearing life, brake cooling,
speedometer/odometer calibration, stopping ability, headlight
aim, bumper height, vehicle ground clearance, and tire or snow
chain clearance to the body and chassis.
CAUTION
Observe the following instructions. Otherwise, an
accident may occur resulting in death or serious
injuries.
 Do not use wheels other than the manufacturer's
recommended size, as this may cause dangerous
handling characteristics resulting in loss of control.
 Do not use wheels of different brands, sizes and
types, as this may cause dangerous handling
characteristics resulting in loss of control.
