A WORD ABOUT YOUR KEYS
The keys for your new vehicle are enclosed in a plastic
bag with the key code number on it. If you received your
keys without the bag, ask your dealer to give you the
number. The key code can also be obtained by the dealer
from your vehicle invoice.
Ignition Key
Insert the key fully, then turn the switch to one of the four
illustrated positions. The key can be inserted or with-
drawn only in the LOCK position. The automatic trans-
mission gear selector must be in the P (Park) position.
