hand by approximately the same amount.When replacing an aluminum
wheel with a steel wheel, tighten
the wheel nuts until the tapered
portion comes into loose contact
with the disc wheel seat.

■After completing the tire change
The tire pressure warning
system must be reset. (P. 515)
■When using the spare tire
As the spare tire is not equipped with a tire pressure warning valve and
transmitter, low inflation pressure of the spare tire will not be indicated by
the tire pressure warnin g system. Also, if you replace the compact spare
tire after the tire pressure warning light comes on, the light remains on.
CAUTION
■Using the tire jack
Improper use of the tire jack may cause the vehicle to suddenly fall off
the jack, leading to death or serious injury.
●Do not use the tire jack for any pu rpose other than replacing tires or
installing and removing tire chains.
●Only use the tire jack that comes wi th this vehicle for replacing a flat
tire.
Do not use it on other vehicles, and do not use other tire jacks for
replacing tires on this vehicle.
●Always check that the tire jack is securely set to the jack point.
●Do not put any part of your body under the vehicle while it is supported
by the jack.
●Do not start or run the engine while your vehicle is supported by the
jack.
●Do not raise the vehicle while someone is inside.
●When raising the vehicle, do not put an object on or under the jack.
●Do not raise the vehicle to a hei ght greater than that required to
replace the tire.
●Use a jack stand if it is necessary to get under the vehicle.
Take particular care when lowering the vehicle to ensure that no one
working on or near the vehicle may be injured.

CAUTION
■Using the jack handle
Tighten all the jack handle bolts securely using a Phillips-head screw-
driver, to prevent the extension parts from coming apart unexpectedly.
■Replacing a flat tire
Observe the following precautions to reduce the risk of death or serious
injury.
●Lower the spare tire completely to the ground before removing it from
under the vehicle.
●Do not try to remove the wheel ornament by hand. Take due care in
handling the ornament to avoid unexpected personal injury.
●Never use oil or grease on the wheel bolts or wheel nuts.
Oil and grease may cause the wheel nuts to be excessively tightened,
leading to bolt or disc wheel damage. In addition, the oil or grease can
cause the wheel nuts to loosen and the wheel may fall off, causing a
serious accident. Remove any oil or grease from the wheel bolts or
wheel nuts.
●Have the wheel nuts tightened with a torque wrench to 83 ft•lbf (110
N•m, 11.5 kgf•m) as soon as possible after changing wheels.
●Do not attach a heavily damaged wheel ornament, as it may fly off the
wheel while the vehicle is moving.
●When installing a tire, only use whee l nuts that have been specifically
designed for that wheel.
●If there are any cracks or deformatio ns in the bolt screws, nut threads
or bolt holes of the wheel, have the vehicle inspected by your Toyota
dealer.
Failure to follow these precautions could cause the wheel nuts to loosen
and the tire to fall off, result ing in death or serious injury.
