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 loose
fit) and turn it clockwise. As the jack touches the vehicle and begins
to lift, doublecheck that it is properly positioned.
CAUTION
Never get under the vehicle when the vehicle is supported by
the jack alone.

7. Remove the wheel nuts and remove the flat tire.
Lift the flat tire straight off and put it aside.

Before putting on the wheel, remove any corrosion on the mounting
surfaces with a wire brush or such. Installation of wheels without
good metaltometal contact at the mounting surface can cause
wheel nuts to loosen and eventually cause a wheel to come off while
driving.

8. Reinstall all the wheel nuts finger tight.
Align the holes in the wheel with the bolts. Then lift up the wheel
and get at least the top bolt started through its hole. Wiggle the tire
and press it back over the other bolts.
Reinstall the wheel nuts and tighten them as much as you can by
hand. Press the tire back and see if you can tighten them more.

9. Lower the vehicle completely and tighten the wheel nuts.
Turn the jack handle counterclockwise to lower the vehicle.
Use only the wheel nut wrench to tighten the nuts. Do not use other
tools or any additional leverage other than your hands, such as a
hammer, pipe or your foot. Make sure the wrench is securely
engaged over the nut.
Tighten each nut a little at a time in the order shown. Repeat the
process until all the nuts are tight.
CAUTION
When lowering the vehicle, make sure all portions of your
body and all other persons around will not be injured as the
vehicle is lowered to the ground.
As soon as possible after changing wheels, have the wheel
nuts tightened by torque wrench at 103 N·m (10.5 kgf·m, 76
ft·lbf.).

10. Reinstall the wheel ornament.
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
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.

DOITYOURSELF SERVICE
PRECAUTIONS
If you perform maintenance yourself, be sure to follow the
correct procedure given in this Section.
You should be aware that improper or incomplete servicing may
result in operating problems.
Performing doityourself maintenance during the warranty period
may affect your warranty coverage. Read the separate Lexus
Warranty statement for details and suggestions.
This Section gives instructions only for those items that are
relatively easy for an owner to perform. As explained in Section 5,
there are still a number of items that must be performed by a qualified
technician with special tools.
For information on tools and parts for doityourself maintenance,
see ”Parts and tools”.
Utmost care should be taken when working on your vehicle to
prevent accidental injury. Here are a few precautions that you should
be especially careful to observe:
CAUTION
When the engine is running, keep hands, clothing, and tools
away from the moving fan and engine drive belt.
(Removing rings, watches, and ties is advisable.)
Right after driving, the engine compartment the engine,
radiator, exhaust manifold and power steering fluid
reservoir, etc. will be hot. So be careful not to touch them.
Oil and other fluids may also be hot.
Do not smoke, cause sparks or allow open flames around
fuel or the battery. Their fumes are flammable.
Be extremely cautious when working on the battery. It
contains poisonous and corrosive sulfuric acid.
Do not get under your vehicle with just the body jack
supporting it. Always use automotive jack stands or other
solid supports.
Be sure the ignition is off if you work near the electric
cooling fan or radiator grille. With the ignition on, the
electric cooling fan may automatically start to run if the air
conditioning is on and/or if the coolant temperature is high.
Use eye protection whenever you work on or under your
vehicle where you may be exposed to flying or falling
material, fluid spray, etc.
