Changing a Flat Tire
If a tire goes at, avoid further tire and wheel damage
by driving slowly to a level place. Turn on your

or other people. You and they could be badly
injured or even killed. Find a level place to

while the vehicle is raised.
4. Do not allow passengers to remain in the
vehicle.
5. Put the wheel blocks at the front and rear of
the tire farthest away from the one being
changed. That would be the tire on the
other side, at the opposite end of the
vehicle.The following steps will tell you how to use the jack and
change a tire.

Look at the silver-colored band inside the fuse. If the
band is broken or melted, replace the fuse. Be sure you
replace a bad fuse with a new one of the identical
size and rating.
Spare fuses and a fuse puller are located in the
underhood fuse block. You can remove fuses with the
fuse puller. Remember to replace any of the spare fuses
you use, so you will have some if you ever need them
again.
If you ever have a problem on the road and don’t have
a spare fuse, you can borrow one that has the same
amperage. Just pick some feature of your vehicle
that you can get along without – like the radio or
cigarette lighter – and use its fuse, if it is the correct
amperage. Replace it as soon as you can.
There are two fuse blocks in your vehicle: one is inside
the vehicle and one is in the engine compartment.Instrument Panel Fuse Block
The fuse block is located on the lower portion of the
instrument panel on the driver’s side.
