Doors and Locks
Door Locks
{ CAUTION
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. You increase the
chance of being thrown out of
the vehicle in a crash if the
doors are not locked. So,
wear safety belts properly
and lock the doors whenever
you drive.

CAUTION (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
your vehicle whenever you
leave it.
• Outsiders can easily enter
through an unlocked door
when you slow down or stop
your vehicle. Locking your
doors can help prevent this
from happening.
To manually lock or unlock your
vehicle, use the key in the driver’s
door from the outside to unlock
it. When the driver door is opened
the entire vehicle is unlocked. There
are also window sill knobs that
unlock each door from the inside.
