4. Loosen all the wheel nuts.
Always loosen the wheel nuts before raising the vehicle.
Turn the nuts counterclockwise to loosen them. To get maximum leverage,
fit the wrench to the nut so that the handle is on the right side, as shown\
above.
Grab the wrench near the end of the handle and pull up on the handle. Be
careful that the wrench does not slip off the nut.
Do not remove the nuts yet ± just unscrew them about one±half turn\
.

5. Position the jack at the jack points as shown.
Make sure the jack is positioned on a level and solid surface.

6. After making sure no one is in the vehicle, raise it high enough so that
the spare tire can be installed.
Allow for the fact that you need more ground clearance when putting on the
spare tire than when removing the flat tire.
To raise the vehicle, insert the jack handle into the jack (it is a loos\
e fit) and
turn it clockwise. As the jack touches the vehicle and begins to lift,
double±check that it is properly positioned.
CAUTION
Never get under the vehicle when the vehicle is supported by
the jack alone.

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 º(d) Emergency towingº on page 17\
6.
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 few 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.
(a) Towing with a wheel lift type truck
 From front
40E018±2
Release the parking brake.
NOTICE
When lifting wheels, take care to ensure adequate ground clearance for
towing at the opposite end of the raised vehicle. Otherwise, the bumper
and/or underbody of the towed vehicle will be damaged during towing.

CHASSIS
210
Warning: The traction grade assigned to this tire is based on braking (straigh\
t
ahead) traction tests and does not include cornering (turning) traction.
Temperature A, B, C
± The temperature grades are A (the highest), B, and
C, representing the tire's resistance to the generation of heat and its ability to
dissipate heat when tested under controlled conditions on a specified indoor
laboratory test wheel. Sustained high temperature can cause the material of
the tire to degenerate and reduce tire life, and excessive temperature can \
lead
to sudden tire failure. The grade C corresponds to a level of performan\
ce
which all passenger car tires must meet under the Federal Motor Vehicle
Safety Standard No. 109. Grades B and A represent higher levels of
performance on the laboratory test wheel than the minimum required by law.
Warning: The temperature grade of this tire established for a tire that is
properly inflated and not overloaded. Excessive speed, underinflation, or
excessive loading, either separately or in combination, can cause heat buildup
and possible tire failure.
Tire selection
When replacing a tire, use only the same size and construction as
originally installed and with the same or greater load capacity.
Using any other size or type of tire may seriously affect handling, ride,
speedometer/odometer calibration, ground clearance, and clearance between
the body and tires or snow chains.
Do not mix radial, belted, or conventional tires on your vehicle.
Do not use tires or wheels other than the manufacturer's recommended
size.
It can cause dangerous handling characteristics, resulting in loss of co\
ntrol.
If you need to change from conventional tires to radial tires or vice ve\
rsa,
replace them as a set.
INSTALLING SNOW TIRES AND CHAINS
When to use snow tires or chains
Snow tires or chains are recommended when driving on snow or ice.
On wet or dry roads, conventional or radial tires provide better traction \
than
snow or studded tires.
Snow tire selection
If you need snow tires, select the same size, construction and load capacity
as the original tires on your Lexus.
Do not use tires other than stated above. Since your vehicle has radial t\
ires
as original equipment, make sure your snow tires also have radial
construction. Do not install studded tires without first checking local
regulations for possible restrictions.
Snow tire installation
Snow tires should be installed on all wheels.
Installing snow tires on the front wheels only can lead to an excessive
difference in road grip capability between the front and rear tires which could
cause loss of vehicle control.

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 damaged wheels, a tire may slip off a wheel or they may
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.
ALUMINUM WHEEL PRECAUTIONS
 After driving your vehicle the first 1600 km (1000 miles), check that the
wheel nuts are tight.
 If you have rotated, repaired, or changed your tires, check that the whe\
el
nuts are still tight after driving 1600 km (1000 miles).
 When using tire chains, be careful not to damage the aluminum wheels.
 Use only the Lexus wheel nuts and wrench designed for your aluminum
wheels.
 When balancing your wheels, use only Lexus balance weights or
equivalent and a plastic or rubber hammer.
 As with any wheel, periodically check your aluminum wheels for damage.
If damaged, replace immediately.
SUSPENSION AND CHASSIS
CAUTION
Do not modify the suspension/chassis with lift kits, spacers,
springs, etc. It can cause dangerous handling characteristics,
resulting in loss of control.
