Be sure the hoist end of the extension connects to
the hoist shaft (E). The ribbed square end of the
extension is used to lower the spare tire.
4. Turn the wheel wrench (H) counterclockwise to
lower the spare tire to the ground. Continue to
turn 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.5. The wheel wrench has
a hook that allows you
to pull the hoist
cable towards you to
assist in reaching
the spare tire.

lowered, tilt the
retainer (D) at the end
of the cable so it
can be pulled up
through the wheel
opening.
7. Put the spare tire near the at tire.

Removing the Flat Tire and Installing
the Spare Tire
Use the following pictures and instructions to remove
the at tire and raise the vehicle.
The tools you’ll be using include the bottle jack (A), the
wheel blocks (B), the jack handle (C), the jack handle
extensions (D), and the wheel wrench (E).1. If your vehicle has
wheel nut caps, loosen
them by turning the
wheel wrench
counterclockwise. If the
vehicle has a center
cap with wheel
nut caps, the wheel nut
caps are designed to

loosened. Remove the
entire center cap.
If the wheel has a smooth center cap, place the
chisel end of the wheel wrench in the slot on
the wheel and gently pry out.
