Removing the Wheel Covers
If the wheel has a center cap, use the handle of the
folding wrench to pry it off. Then, with the other end of
the folding wrench, loosen the nuts.
If your vehicle has the plastic "bolt-on" wheel covers,
loosen the bolts completely using the folding wrench,
and remove the wheel cover.
Removing the Flat Tire and Installing
the Spare Tire
1. Loosen the wheel
nuts
-
but do not
remove them
-
using
the folding wrench.
(Turn the handle about
180 degrees, then flip
the handle back to
the starting position.
This avoids taking the
wrench off the lug nut
for each turn.)
For wheels with a wheel lock key, use the wheel
lock key between the lock nut and folding wrench.
The key is supplied in the front passenger door
pocket.
Notice: To help avoid damage to lock nut or wheel
lock key, do not use an impact wrench with this key.
