Installing the Spare Tire
You vehicle may have wheels with exposed wheel nuts.
If so, go to the Removing the Wheel Nuts section. If the
vehicle has steel wheel covers with plastic nut caps, the
wheel nuts are hidden behind the cap. To remove the
wheel cover:
1. Do a safety check before proceeding. SeeChanging
a Flat Tire on page 5-76.
2. Turn the wheel wrench counterclockwise to loosen
the plastic wheel nut caps.
If needed, nish loosening them by hand. The nut
caps will not come off of the wheel cover.
The edge of the wheel cover could be sharp, so do
not try to remove the cover with your bare hands.
Do not drop the cap or lay it face down, as it could
become scratched or damaged.
Store the wheel cover in the trunk until you have
the at tire repaired or replaced.
Once you have removed the wheel cover or plastic nut
caps, use the following procedure to remove the at
tire and install the spare tire.
