WARNING
Unlocked doors can be
dangerous.
. Passengers, especially
children, can easily open
the doors and fall out of a
moving vehicle. When a door
is locked, the handle will not
open it. The chance of being
thrown out of the vehicle in
a crash is increased if the
doors are not locked. So, all
passengers should wear
safety belts properly and
the doors should be locked
whenever the vehicle is
driven.

WARNING (Continued)
. Young children who get into
unlocked vehicles may be
unable to get out. A child can
be overcome by extreme heat
and can suffer permanent
injuries or even death from
heat stroke. Always lock the
vehicle whenever leaving it.
. Outsiders can easily enter
through an unlocked door
when you slow down or stop
the vehicle. Locking the doors
can help prevent this from
happening.
There are several ways to lock and
unlock the vehicle.

locks, push down or pull up on the
manual lock knob.
