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.
40L0121
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.
40L0141
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.

IF YOUR VEHICLE NEEDS TO BE
TOWED
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 ”(d)
Emergency towing” on page 208.
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
40L021
Use a towing dolly under the rear wheels.
NOTICE
Never tow a vehicle with an automatic transmission from the
front with rear wheels on the ground, as this may cause serious
damage to the transmission.

IN CASE OF AN EMERGENCY
206From rear
40L0221
Place the ignition key in the ”ACC” position.
NOTICE
Do not tow with the key removed or in the ”LOCK” position,
as the steering lock mechanism is not strong enough to hold
the front wheels straight.
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.
(b) Using a flat bed truck

If your Lexus is transported by a flat bed, it should be tied down
at locations A and B as shown above.
40L0191
Rear emergency towing eyelets
NOTICE
Do not use the rear emergency towing eyelets.
For vehicles sold in U.S.A., before your vehicle is transported
by flat bed, the height control switch, if so equipped, must be
in the ”HIGH” mode.
Tie down angle

If you use chains or wires to tie down your vehicle, the angles
shaded black must be at 45.

(c) Towing with a sling type truck
40L0231
NOTICE
Do not tow with a sling type truck, either from the front or rear.
This may cause body damage.
(d) Emergency towing
40L0311
If towing is necessary, we recommend you to have it done by your
Lexus dealer or a commercial tow truck service.
If towing service is not available in an emergency, your vehicle
may be temporarily towed by a cable or chain secured to the
emergency towing eyelet. Use extreme caution when towing the
vehicle.
A driver must be in the vehicle to steer it and operate the brakes.
Towing in this manner may be done only on hardsurfaced roads for
a short distance and at low speeds. Also, the wheels, axles, drive
train, steering and brakes must all be in good condition.

IN CASE OF AN EMERGENCY
209
CAUTION
Use extreme caution when towing the vehicle. Avoid sudden
starts or erratic driving maneuvers which would place
excessive stress on the emergency towing eyelet and towing
cable or chain. The eyelet and towing cable or chain may
break and cause serious injury or damage.
NOTICE
Use only a cable or chain specifically intended for use in towing
vehicles. Securely fasten the cable or chain to the towing eyelet
provided.
Before towing, release the parking brake and put the transmission in
”N”. The ignition key must be in ”ACC” (engine off) or ”ON”
(engine running).
CAUTION
If the engine is not running, the power assist for the brakes and
steering will not work so steering and braking will be much
harder than usual.
IF YOU CANNOT SHIFT
AUTOMATIC TRANSMISSION
SELECTOR LEVER
40L025-3
If you cannot shift the selector lever, use the shift lock override
button as follows:
1
Turn the ignition key to ”LOCK” or ”ACC”. Make sure the

screwdriver or equivalent.
