5. 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.
6. Remove the wheel nuts and remove the flat tire.
Lift the flat tire straight off and put it aside.

IN CASE OF AN EMERGENCY
2969. After
changing the wheel, check the air pr essure 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 NEEDS TOBE 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 car efully in accordance with the instructions given
in º(d) Emergency towingº on page 303.
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 few 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
299
Place the ignition key in the ºACCº position.
NOTICE

Do not tow with the key removed or in the ºLOCKº
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.
(b) Using a flat bed truck

IN CASE OF AN EMERGENCY
301
If your Lexus is transported by a flat bed, it should be tied
down at locations A and B as shown above.
