CAUTION:
{
The underbody-mounted spare tire needs to be
stored with the valve stem pointing up. If the
spare tire is stored with the valve stem
pointing downward, its secondary latch won't
work properly and the spare tire could loosen
and suddenly fall from your vehicle. If this
happened when your vehicle was being driven,
the tire might contact a person or another
vehicle, causing injury and, of course, damage
to itself as well. Be sure the
underbody-mounted spare tire is stored with
its valve stem pointing up.
Notice: An aluminum wheel with a flat tire should
always be stored under the vehicle with the
hoist. However, storing it that way for an extended
period could damage the wheel. To avoid this,
always stow the wheel properly with the valve stem
pointing up and have the wheel repaired as soon
as possible.
Follow this diagram to store the underbody-mounted
flat or spare tire.
1. Put the tire (E) on the ground at the rear of the
vehicle.
2. Remove the hubcap, if equipped, from the flat tire
by tapping the backside of the hubcap with the
wheel wrench (A). Store in a safe location until
the flat tire is repaired. Once the tire is repaired,
replace the hubcap.
3. Ensure the valve stem is pointed up and to the rear.
Then pull the retainer (D) through the wheel.
4. Put the socket end of the extension (C), on a
45 degree angle downward, through the hole just
above the rear bumper and into the hoist shaft (B).
