Oldsmobile 2001 Silhouette - Manual (Page 321)

5-25
If your vehicle has the plastic “bolt - on” wheel
covers, loosen them completely using the folding
wrench, and remove the wheel cover.
2. 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 the lock nut or the wheel
lock key, do not use an impact wrench with this key.
