7. If your vehicle has aluminum wheels, each wheel nut is covered with a nylon cap. Use the folding wrench to remove the nylon caps from the wheel nuts before you loosen the nuts. If your vehicle has the plastic "bolt-on" wheel covers, you cannot separate the nylon wheel nut caps from the cover. Loosen them completely using the folding wrench, and remove the wheel cover. If the wheel nut caps have been completely loosened, the wheel cover will come off easily. 8. If your vehicle has aluminum wheels, each wheel may have one wheel locknut in place of a standard wheel nut. A special wheel lock key (removal tool) and instructions are stored in your glove box. Attach the wheel lock key to the socket of the folding wrench. Remove the locking wheel nut by turning it counterclockwise. If your vehicle has the plastic "bolt-on" wheel covers, you will not have a locking wheel nut. 9. Loosen the wheel nuts -- but do not remove them -using the folding wrench. 10. Attach the folding wrench to the jack, and rotate the wrench clockwise to raise the jack head a few inches. 5-29
