HOW TO USE THIS MANUAL
CONTENTS INDICATION OF DESTINATPN
The preceding page contains GROUP INDEX which Europe, General Export, Australia and New Zealand
lists the group title and group number. used for convenience to indicate destination.
PAGE NUMBERS
All page numbers consist of two sets of digits
separated by a dash. The digits preceding the
dash indentify the number of the group. The digits
following the dash represent the consecutive page
number within the group. The page numbers can
be found on the top left or right of each page.
NOTE
1. "General Exporf' means territories other than
Europe, Australia, New Zealand, the U.S.A.
and Canada.
2. "GCC" indicates aclassification within the models
for General Export category: models for
countries that are members of the (Persian
Gulf Cooperation Council of nations.
3. In some instances, vehicles with other
