ating range. To prevent theft, however, it is
advisable to only unlock the vehicle when
you are in close proximity to it.

When leaving the vehicle, always remove the
SmartKey from the starter switch, take it
with you, and lock the vehicle. Do not leave
children unattended in the vehicle, or with
access to an unlocked vehicle. A child’s un-
supervised access to a vehicle could result
in an accident and/or serious personal inju-
ry.
Warning!G
To prevent possible personal injury, always
keep hands and fingers away from the door
or trunk lid opening when closing a door or
the trunk. Be especially careful when small
children are around.
