5. Position the jack at the jack points as shown.
Front — Under the frame side rail
Rear — Under the rear axle housing
NOTICE
Make sure to place the jack as shown in
illustrations. Otherwise, your vehicle may be
damaged.
Make sure the jack is positioned on a level and solid
surface.
1Jack handle end
2Jack handle extension with bolt
3Jack handle extension without bolt
4Jack handle
Put a jack handle, jack handle extensions and jack
handle end together as shown in the illustration.
CAUTION
Make sure they are securely fixed with the
screws.

IN CASE OF AN EMERGENCY
442
When connecting a jack handle extension with a jack
handle end, use a Phillips−head screwdriver or jack
handle to tighten the bolts on the joints as shown in
the illustration. When connecting the jack handle with
extension, tighten the bolt on the jack handle securely.
Make sure the hollow meets the bolt on any joint when
you tighten the bolts.
NOTICE
Tighten all the joints securely. Otherwise, the
extension may come off and it may damage the
paint or vehicle body.
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 extension
into the jack (it is a loose fit) and turn it clockwise
with the handle, making sure the handle remains firmly
fitted onto the jack handle extension. As the jack
touches the vehicle and begins to lift, double −check
that it is properly positioned.

IN CASE OF AN EMERGENCY
443
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.
Roll the spare wheel into position and 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.
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.

8. Reinstall all the wheel nuts finger tight.
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 loose 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.
To lower the vehicle, turn the jack handle extension
counterclockwise with the handle, making sure the
handle remains firmly fitted onto the jack handle
extension.
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.

IN CASE OF AN EMERGENCY
445
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.
 Have the wheel nuts tightened with torque
wrench to 112 N·m (11.5 kgf·m, 83 ft·lbf), as
soon as possible after changing wheels.
Otherwise, the nuts may loosen and the
wheels may fall off, which could cause a
serious accident.
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.
 Do not attach a heavily damaged plastic wheel
ornament. It may fly off the wheel and cause
accidents while the vehicle is moving.

IN CASE OF AN EMERGENCY
446
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 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.
In this situation, lock the center differential and turn off the
vehicle stability control system. (For details, see
“Fourwheel drive system” on page 356.)
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.

IN CASE OF AN EMERGENCY
447
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 is
completely shifted to forward or reverse gear.
 Do not race the engine and avoid spinning the
wheels.
 If your vehicle remains stuck after rocking the vehicle
several times, consider other ways such as towing.
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 451.
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.

IN CASE OF AN EMERGENCY
448TOWING 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.
CAUTION
When
your vehicle is towed, put the vehicle height in the
“N” (normal) mode and push the “HEIGHT CONTROL
OFF” switch to turn off the rear height control air
suspension. Otherwise, the vehicle height may be
changed in the automatic leveling function, resulting in
accident. For details, see “Rear height control air
suspension” on page 366.
