CAUTION
Never use oil or grease on the
bolts or nuts. The nuts may loos-
en and the wheels may fall off,
which could cause a serious ac-
cident.
CAUTION
When jacking, be sure to observe
the following to reduce the possi-
bility of death or serious injury:
Follow jacking instructions.
 Do not put any part of your
body under the vehicle sup-
ported by the jack. Otherwise,
personal injury may occur.
 Do not start or run the engine
while your vehicle is supported
by the jack.
 Stop the vehicle on a level firm
ground, firmly set the parking
brake and put the transmission
in “P”. Block the wheel diago-
nally opposite to the one being
changed if necessary.
Make sure to set the jack prop-
erly in the jack point. Raising
the vehicle with jack improper-
ly positioned will damage the
vehicle or may allow the ve-
hicle 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 place any objects on top
of or underneath the jack.
 Raise the vehicle only high
enough to remove and change
the tire.

clearance when putting on the spare
tire than when removing the flat tire.

Lift the flat tire straight off and put it
aside.
Roll the spare wheel into position and
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.Before putting on wheels, remove any
corrosion on the mounting surfaces
with a wire brush or such. Installation

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 seri-
ous accident. If there is oil or
grease on any bolt or nut, clean
it.

wise to lower the vehicle.
Use only the wheel nut wrench to

the order shown. Repeat the process
until all the nuts are tight.
