4. Loosen all the wheel nuts.
Always loosen the wheel nuts before raising the vehicle.
Turn the wheel 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.

7. Remove the wheel nuts and remove the flat tire.
Lift the flat tire straight off and put it aside.
SS41027
(Only for vehicles equipped with 215/45R17 tires)
When installing the alloy wheels, at this point, remove the
wheel ornament from the flat tire and replace it on the newly
installed tire.
SS41012
Before putting on the wheel, remove any corrosion on the
mounting surfaces with a wire brush or such. Installation of
wheels without good metal±to±metal contact at the mounting
surface can cause wheel nuts to loosen and eventually cause
a wheel to come off while driving.

10. Reinstall the wheel ornament.(Only for vehicles equipped with P205/55R16 tires.)
Put the wheel ornament into position and then tap it firmly with
the side or heel of your hand to snap it into place.
CAUTION
Take due care in handling the ornament to avoid
unexpected personal injury.
11. After changing the wheel, check the air pressure of the
replaced tire. Stow all the tools, jack and flat tire securely.
If the pressure of the replaced tire is low, drive slowly to the
nearest service station and fill to the correct pressure.
Do not forget to reinstall the tire valve cap as dirt and moisture
could get into the valve core and possible cause air leakage.
If the cap is missing, put a new one on as soon as possible.
This is the same procedure for changing or rotating your tires.
CAUTION
 When reinstalling a standard tire, take due care in
handling the ornament to avoid unexpected personal
injury.
 Before driving, make sure all the tools, jack and flat
tire are securely in place in their storage location to
reduce the possibility of personal injury during a
collision or sudden braking.

Where to go for service?
Lexus technicians are well±trained specialists and are kept up
to date with the latest service information through technical
bulletins, service tips, and in±dealership training programs.
They are well informed about the operation of all the systems
on your vehicle.
You can be confident that your Lexus dealer's service
department performs the best job to meet the maintenance
requirements of your vehicle.

be sure to keep a copy of the repair order for any service
performed on your Lexus.
What about do±it±yourself maintenance?
Many of the maintenance items are easy to do yourself, if you
have a little mechanical ability and a few basic automotive
tools. Simple instructions for how to perform them are
presented in Section 6.
If you are a skilled do±it±yourself mechanic, the Lexus service
manuals are recommended. Please be aware that
do±it±yourself maintenance can affect your warranty
coverage. See ºOwner's Guideº, ºOwner's Manual

DOES YOUR VEHICLE NEEDREPAIRING?
Be on the alert for changes in performance and sounds, and
visual tip±offs that indicate service is needed. Some important
clues are:

Engine missing, stumbling, or pinging

Appreciable loss of power

Strange engine noises

A fluid leak under the vehicle (however, water dripping from
the air conditioning after use is normal.)

Change in exhaust sound (This may indicate a dangerous
carbon monoxide leak. Drive with the windows open and
have the exhaust system checked immediately.)

Flat±looking tires, excessive tire squeal when cornering,
uneven tire wear

Vehicle pulls to one side when driving straight on a level
road

Strange noises related to suspension movement

Loss of brake effectiveness, spongy feeling brake pedal,
pedal almost touches floors, vehicle pulls to one side when
braking

Engine coolant temperature continually higher than normal
If you notice any of these clues, take your vehicle to your Lexus
dealer as soon as possible. It probably needs adjustment or
repair.
CAUTION
Do not continue driving with the vehicle unchecked. It
could result in serious vehicle damage and possibly
personal injury.
