Storing the Tools
To store the tools:
1. Return the tools (wheel wrench, jack
handle, and jack handle extensions) to
the tool bag. Use the velcro straps to
secure the tool bag under the load floor
in the cargo area.
2. Position the jack and wheel blocks in the
driver side trim panel over the
wheelhouse.
3. Turn the jack knob clockwise until the
jack is secured tight in the mounting
bracket. Be sure to position the holes in
the base of the jack onto the pin in the
mounting bracket.
4. Close the trim panel door.
Storing a Flat Tire Inside of the Vehicle
If the vehicle has 275/60R20 or 275/50R22
size tires, the flat tire must be stored inside
of the vehicle in the cargo area using the
flat tire secure strap inside the glove box.
1. Store the tools. See
“
Storing the Tools
”
earlier in this section.
2. If the vehicle has a short wheel base, the
third row seat must be folded down to
provide sufficient space to store the flat
tire. If the third row seat cannot be
folded down, the flat tire cannot be
stored and must be left in a safe
location, to be picked up at a later time.
3. Once there is sufficient space in the rear
of the vehicle, lift the flat tire and place
it on top of the load floor, with the
valve stem pointed up.
4. Remove the flat tire secure strap from
the glove box and place the loop end of
the strap through the cargo tie-down.
Place the hook end of the strap through
the loop and pull it until the strap is
fastened securely to the tie-down.
5. Route the hook end of the strap through
the wheel, as shown.
6. Attach the hook to the other cargo
tie-down in the rear of the vehicle.
7. Tighten the strap.
