IN CASE OF AN EMERGENCY
406
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.
 For vehicles equipped with the height control
switch, be sure to turn the ignition switch off
before jacking. If this is not done, the vehicle
height adjustment function will operate, which
may cause an accident.NOTICE
Do not continue driving with a deflated tire.
Driving even a short distance can damage a tire
and wheel beyond repair.

2. Block the wheel diagonally opposite the flat tire to
keep the vehicle from rolling when it is jacked up.
When blocking a wheel, place a wheel block in front of
one of the front wheels or behind one of the rear wheels.
40L161
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.

40L165
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.
40L166
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.
Have the wheel nuts tightened with torque
wrench to 103 N·m (10.5 kgf·m, 76 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. 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.

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 420.
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.

IN CASE OF AN EMERGENCY
417
(a) Towing with a wheel lift type truck
From front
40L171
Use a towing dolly under the rear wheels.
NOTICE
Never tow a vehicle from the front with rear wheels on
the ground, as this may cause serious damage to the
transmission.
From rear
40L172
Place the ignition switch in the “ACC” position.
NOTICE
Do not tow with the key removed or in the “LOCK”
position, 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.

(d) Emergency towing
40L217
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.
To install the front towing eyelet, see “Installing towing eyelet”
on page 422.
NOTICE
 Only use specified towing eyelet; otherwise your
vehicle may be damaged.
 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 eyelet
and towing cable or chain. The eyelet and towing cable
or chain may break and cause serious injury or damage.
NOTICE
Use only a cable or chain specifically intended for use
in towing vehicles. Securely fasten the cable or chain
to the towing eyelet provided.
Before towing, release the parking brake and put the
transmission in “N”. The ignition switch must be in “ACC”
(engine off) or “ON” (engine running).
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.

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.
