Removing the Wheel Covers
If your vehicle is equipped with wheel covers, be sure to
use a wheel wrench to begin the process of loosening
the plastic wheel nut caps.
Once you have loosened
the plastic nut caps with
the wheel wrench, if
needed, you can finish
loosening them with your
fingers.
Then, using the flat end
o f
the wheel wrench, pry along
the edge of the wheel cover until it comes off. Be
careful; the edge may be sharp. Don't try to remove the
cover with your bare hands.
Removing the Wheel Center Caps
To remove a center cap,
use the wrench to pry
gently at the notch.
Don't use a tool that is
narrower than the wrench
to pry at this notch.
Then pry off the cap.
