2. Turn the wheel wrench counterclockwise to lower the spare tire. Keep turning the wheel wrench until the spare tire can be pulled out from under the vehicle. If the spare tire does not lower to the ground, the secondary latch is engaged causing the tire not to lower. See "Secondary Latch System" later in this section. When the tire has been completely lowered, tilt the retainer at the end of the cable and pull it through the wheel opening. Pull the tire out from under the vehicle. Notice: If you drive away before the spare tire or secondary latch system cable has been reinstalled, you could damage your vehicle. Always reinstall this cable before driving your vehicle. 3. Put the spare tire near the flat tire. 4. Position the chisel end of your wheel wrench in the notch of the center cap and pry off the center cap. See "Removing the Flat Tire and Installing the Spare Tire" later in this section to continue changing the flat tire. 5-77
