of the wheel facing up. Then bolt the tire in place and
install the tool tray to prevent the tire from flying forward
during a collision or sudden braking.

2. Block the wheel diagonally opposite the flat tire to
keep the vehicle from rolling when it is jacked up.
When blocking the wheel, place a wheel block in front of
one of the front wheels or behind one of the rear wheels.

3. 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.
CAUTION
Never use oil or grease on the bolts or nuts. The
nuts may loosen and the wheels may fall off, which
could cause a serious accident.

4. Position the jack at the jack points as shown.

surface.

5. 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, double±check that it is
properly positioned.
CAUTION
Never get under the vehicle when the vehicle is
supported by the jack alone.

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

7. Remove the wheel ornament.
When installing the alloy wheels, at this point, remove
the wheel ornament from the flat tire and replace it on the
newly installed tire.

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.
SS41013
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.
CAUTION
Never use oil or grease on the bolts or nuts. Doing
so may lead to overtightening the nuts and
damaging the bolts. The nuts may loosen and the
wheels may fall off, which could cause a serious
accident. If there is oil or grease on any bolt or nut,
clean it.

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 with torque
wrench to 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 possibly
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.

IF YOUR VEHICLE BECOMESSTUCK
If your vehicle becomes stuck in snow, mud, sand, etc.,
then you may attempt to rock the vehicle free by moving
it forward and backward.
Your vehicle is equipped with the traction control system,
turn off the system to become unstuck to allow the tires
to spin enough to remove the vehicle from the
obstruction. (For details, see ªTraction control systemº
on page 252 or 255.)
CAUTION
Do not attempt to rock the vehicle free by moving it
forward and backward if people or objects are anywhere
near the vehicle. During the rocking operation the
vehicle may suddenly move forward or backward as it
becomes unstuck, causing injury or damage to nearby
people or objects.
NOTICE
If you rock your vehicle, observe the following precautions to prevent damage to the transmission and
other parts.
Do not depress the accelerator pedal while shifting the selector lever or before the transmission iscompletely shifted to forward or reverse gear.
Do not race the engine and avoid spinning thewheels.
If your vehicle remains stuck after rocking the vehicleseveral times, consider other ways such as towing.

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 303.
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.
(a) Towing with a wheel lift type truck
From front
SS41015
MANUAL TRANSMISSION:
We recommend using a towing dolly under the rear wheels.
AUTOMATIC TRANSMISSION:
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 thismay cause serious damage to the transmission.

(d) Emergency towing
SV41032
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.
Automatic transmission: Use only the front towing eyelet
when towing your vehicle.
NOTICE
Only use specified towing eyelet; otherwise your vehicle may be damaged.
Automatic transmission: Never tow a vehicle fromthe rear with four wheels on the ground. This maycause serious damage to the transmission.
A driver must be in the vehicle to steer it and operate the
brakes.
Towing in this manner may be done only on hard±surfaced
roads for a short distance and at low speeds. Also, the wheels,
axles, drive train, steering and brakes must all be in good
condition.
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.
