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.
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 131 N·m (13.4 kgf·m, 97 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.
 Do not attach a heavily damaged plastic wheel
ornament. It may fly off the wheel and cause
accidents while the vehicle is moving.

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
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.

(d) Emergency towing
40x600a
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 hook. Use extreme
caution when towing the vehicle.
NOTICE
Never tow a vehicle from the rear with four wheels on the
ground. This may cause 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 hook
and towing cable or chain. The hook and towing cable
or chain may break and cause serious injury or damage.
NOTICE
 Do not use front and rear eyelets. It is not designed
for towing.
 Use only a cable or chain specifically intended for
use in towing vehicles. Securely fasten the cable or
chain to the towing hook provided.
Before towing, check that the center differential is unlocked.
(The indicator light must be off with the ignition on.) Release
the parking brake and put the transmission in “N”. The ignition
key must be in “ACC” (engine off) or “ON” (engine running).

IN CASE OF AN EMERGENCY
356
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.
Emergency towing hook precautions:
Before emergency towing, check that the hook is not broken
or damaged and that the installation bolts are not loose.
 Fasten the towing cable or chain securely to the hook.
 Do not jerk the hook. Apply steady and even force.
 To avoid damaging the hook, do not pull from the side or at
a vertical angle. Always pull straight ahead.
CAUTION
If the emergency towing hook is used to get out when
your vehicle becomes stuck in the mud, sand or other
condition from which the vehicle cannot be driven out
under its own power, make sure to observe the
precautions mentioned below. Otherwise, excessive
stress will be put on the hook and the towing cable or
chain may break, causing serious injury or damage.
If the towing vehicle can hardly move, do not forcibly
continue the towing. Contact your Lexus dealer or a
commercial tow truck service for assistance.
 Tow the vehicle as straight ahead as possible.
 Keep away from the vehicle during towing.
Tips 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 vehic les and towing cable or
chain when towing.
 Remove the sand and soil in the front and the back of the

Safety information for the Lexus Link System
Important!: Read this information before using the Lexus
Link System.
EXPOSURE TO RADIO FREQUENCY SIGNALS
The Lexus Link System to be installed in your vehicle is a low
power radio transmitter and receiver. When the ignition is
turned to the “ON” position, it receives and also sends out radio
frequency (RF) signals.
In August 1996, the Federal Communications Commission
(FCC) adopted RF exposure guidelines with safety levels for
mobile wireless phones. Those guidelines are consistent with
the safety standards previously set by both U.S. and
international standards bodies.

Those standards were based
on comprehensive and periodic
evaluations of the relevant scientific literature. Over 120
scientists, engineers, and physicians from universities,
government health agencies, and industry reviewed the
available body of research to develop the ANSI Standard
(C95.1).
The design of the Lexus Link System complies with the FCC
guidelines in addition to those standards.
