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.

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.

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.

tighten the eyelet securely. If the eyelet is loose, it may
come off when being towed and result in death or
serious injury.

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.
