If you must change a tire ...
1. Before using jack, set parking brake by depressing brake pedal and pull outward on parking brake handle. On steep grades, it may be advisable to block the front or rear wheels as an extra precaution against rolling.
2. Open luggage compartment and unscrew single lug nut to free spare wheel and tire. Remove jack base, jack handle, spare wheel and tire, and bumper jack.
3. Place jack base so that jack lip will contact underside of bumper at outer edge of the vertical bumper bar on the flat tire side of the car. Also place base so that it will be about one inch inward from the outer edge of the bumper.
4. Put the jack mechanism lever in the UP position. Place lip of jack in contact with the underside of the bumper against the outer edge of the vertical bumper bar.
5. Use chisel end of jack handle to remove hub cover. Then place chisel end of the jack in the jack mechanism and jack up the car. Note—If tire to be changed is on a front wheel, jack up only a few notches to be sure jack is secure, then start wheel lug nuts loose before continuing the jacking up process. On rear wheels, the parking brake will hold the wheel so that the nuts can be loosened after the car has been jacked up.
6. On wheels on the left side of the car, the wheel lug nuts are left-hand threaded. To remove them, use the hexagonal wrench end of the jack handle and turn the nuts clockwise. On wheels on the right side of the car, the nuts are removed by turning them counterclockwise. Nuts are installed by turning them in the direction opposite to that used in removing them.
7. Raise car with jack until wheel is free of the road and can revolve freely. This is important to be sure you have enough clearance to install spare. Remove flat tire and wheel and place spare wheel and tire over studs. Install lug nuts and tighten uniformly and firmly.
8. Lower jack by first placing jack mechanism lever in its DOWN position and work the jack with the handle in the same manner as when raising car.
9. Replace tools and spare in this order: Jack shaft and mechanism go into the holder provided at the right of the spare wheel well. Jack mechanism must fit snug against bulge of tire to prevent rattling. Next install the spare wheel and tire, being sure the hinged bolt comes through the wheel hub hole. Place retainer plate over bolt and screw on the retainer nut. Wedge jack handle and jack base between tire and well. Put luggage compartment lid handle in closed position, lock handle and remove key, and close lid.
