5. Read the following instructions thoroughly.
CAUTION
When jacking, be sure to observe the following to
reduce the possibility of personal injury:
 Follow jacking instructions.
 Do not put any part of your body under a vehicle
supported by a jack. Otherwise, personal injury
may occur.
 Do not start or run the engine while your vehicle
is supported by the jack.
 Stop the vehicle on a level firm ground, firmly
set the parking brake and put the transmission
in ”P”. Block the wheel diagonally opposite to
the one being changed if necessary.
 Make sure to set the jack properly in the jack
point. Raising the vehicle with jack improperly
positioned will damage the vehicle or may allow
the vehicle to fall off the jack and cause
personal injury.
 Never get under the vehicle when the vehicle is
supported by the jack alone.
Use the jack only for lifting your vehicle during
wheel changing.
 Do not raise the vehicle with someone in the
vehicle.
 When raising the vehicle, do not put an object
on or under the jack.
 Raise the vehicle only high enough to remove
and change the tire.
NOTICE
Do not use liquid sealants for a flat tire as tire
pressure sensors will be damaged.
 Do not continue driving with a deflated tire.
Driving even a short distance can damage a tire
beyond repair.
 When the tires must be repaired or replaced,
have them repaired or replaced by the nearest
Lexus dealer or authorized tire dealer. The tire
pressure sensors will be affected by the
installation or removal of tires.
 When the tires must be replaced, replace the
grommets for tire pressure sensors as well.

4. 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.
G40008
5. 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.

G40009
6. Position the jack at the jack points as shown.
Make sure the jack is positioned on a level and solid
surface.
G40010
7. 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.

9. 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.
G40014
10. 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.

IN CASE OF AN EMERGENCY

From rear
G40016
Twowheel drive models
Select the engine switch in “ACC” mode.
NOTICE
 Do not tow in “OFF” mode, 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.
G40017
Fourwheel drive models
Use a towing dolly under the front wheels.
NOTICE
Never tow a vehicle with an automatic transmission
from the rear with front wheels on the ground, as this
may cause serious damage to the transmission.

IN CASE OF AN EMERGENCY
488Tips for towing a stuck vehicle:
The following methods are effective to use when your
vehicle is stuck in the mud, sand or other condition from
which the vehicle cannot be driven out under its own
power. Use extreme caution when towing the vehicle. In
addition, keep away from the vehicles and towing cable or
chain when towing.

Remove the sand and soil in the front and the back of the
tires.
 Place stones or wood under the tires.
(e) Installing towing eyelet
G40020
1. Remove the front towing eyelet cover on the front bumper
by using a flathead screwdriver. To protect the bodywork,
place a piece of rag over the cover.
G40021
2. Use the towing eyelet in the trunk. Secure it to the hole on
the bumper by turning clockwise. (For the eyelet location, see
page 474.)

G40022
3. Tighten the towing eyelet securely by a wheel nut wrench.
CAUTION
When installing the eyelet on the vehicle, be sure to
tighten the eyelet securely. If the eyelet is loose, it may
come off when being towed and result in death or
serious injury.
IF YOU CANNOT SHIFT
AUTOMATIC TRANSMISSION SELECTOR LEVER
G40001
If you cannot shift the selector lever, use the shift lock
override button as follows:
1Turn the engine switch off. Make sure the parking brake
is applied. Pry up the cover with a flathead screwdriver
or equivalent.

IN CASE OF AN EMERGENCY
490
G40002
2Insert your finger, the screwdriver or equivalent into the
hole to push down the shift lock override button. You can
shift the selector lever while pushing the button.
For your safety, keep the brake pedal depressed.
Be sure to have the system checked by your Lexus dealer as
soon as possible.
IF YOU LOSE YOUR KEYS OR LOCK YOURSELF OUT
You can purchase a new key at your Lexus dealer if you
can give them the key number and electronic key.
Even if you lose only one key, contact your Lexus dealer to
make a new key. If you lose all your electronic keys, you
cannot make new keys; the whole engine immobilizer must be
replaced.
See the suggestion given in “Keys” on page 8.
You can use the smart access system with push −button start
with the new key. Contact your Lexus dealer for detailed
information.
If your keys are locked in the vehicle and you cannot get a
duplicate, many Lexus dealers can still open the door for you,
using their special tools. If you must break a window to get in,
we suggest breaking the smallest side window because it is the
least expensive to replace. Be extremely cautious to avoid
cuts from the glass.

MAINTENANCE
493
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.
Your copy of the repair order is proof that all required
maintenance has been performed for warranty coverage. If
any problems should arise with your vehicle while under
warranty, your Lexus dealer will promptly take care of it. Again,
be sure to keep a copy of the repair order for any service
performed on your Lexus.
What about doityourself 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 “Owner’s Guide”, “Owner’s Manual
Supplement” or “Warranty Booklet” for the details.
