Door Locks
{Warning
Unlocked doors can be
dangerous.
.Passengers, especially
children, can easily open the
doors and fall out of a moving
vehicle. 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.
.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.(Continued)
Warning (Continued)
.Outsiders can easily enter
through an unlocked door
when slowing or stopping the
vehicle. Lock the doors to
help prevent this from
happening.
To lock or unlock a door from the
outside of the vehicle, use the
Remote Keyless Entry (RKE)
transmitter. Pull the handle once
from the inside to unlock the door,
and a second time to open it.
Power Door Locks
There is a power door lock switch
on the instrument panel.

Manual Rearview Mirror
Push the tab forward for daytime
use and pull it rearward for
nighttime use to avoid glare of the
headlamps from behind.
Automatic Dimming
Rearview Mirror
If equipped, automatic dimming
reduces the glare of headlamps
from behind. The dimming feature
comes on when the vehicle is
started.
Windows
{Warning
Never leave a child, a helpless
adult, or a pet alone in a vehicle,
especially with the windows
closed in warm or hot weather.
They can be overcome by the
extreme heat and suffer
permanent injuries or even death
from heat stroke.
The vehicle aerodynamics are
designed to improve fuel economy
performance. This may result in a
pulsing sound when either rear
window is down and the front
windows are up. To reduce the
sound, open either a front window
or the sunroof, if equipped.
Power Windows
{Warning
Children could be seriously
injured or killed if caught in the
path of a closing window. Never
leave keys in a vehicle with
children. When there are children
in the rear seat, use the window
lockout button to prevent
operation of the windows. See
Keys on page 2-1.

2. Pick up the latch plate and pullthe belt across you. Do not let it
get twisted.
The lap-shoulder belt may lock if
you pull the belt across you very
quickly. If this happens, let the
belt go back slightly to unlock it.
Then pull the belt across you
more slowly.
If the shoulder portion of a
passenger belt is pulled out all
the way, the child restraint
locking feature may be engaged.
If this happens, let the belt go
back all the way and start again.
If the webbing locks in the latch
plate before it reaches the
buckle, tilt the latch plate flat to
unlock.3. Push the latch plate into the
buckle until it clicks.
Pull up on the latch plate to
make sure it is secure. If the belt
is not long enough, see Safety
Belt Extender on page 3-18.

the buckle so that the safety belt
could be quickly unbuckled if
necessary.

3-16 Seats and Restraints
After the height adjuster is set to the
desired position, try to move it down
without pressing the release button
to make sure it has locked into
position. Press the release button to
lower the height adjuster.
Safety Belt Pretensioners
This vehicle has safety belt
pretensioners for front outboard
occupants. Although the safety belt
pretensioners cannot be seen, they
are part of the safety belt assembly.
They can help tighten the safety
belts during the early stages of a
moderate to severe frontal, near
frontal, or rear crash if the threshold
conditions for pretensioner
activation are met. Safety belt
pretensioners can also help tighten
the safety belts in a side crash or a
rollover event.
Pretensioners work only once. If the
pretensioners are activated in a
crash, the pretensioners and
possibly other parts of the safetybelt system will need to be replaced.
See
Replacing Safety Belt System
Parts after a Crash on page 3-19.
Rear Safety Belt Comfort
Guides
Rear safety belt comfort guides may
provide added safety belt comfort
for older children who have
outgrown booster seats and for
some adults. When installed on a
shoulder belt, the comfort guide
positions the shoulder belt away
from the neck and head.
This vehicle has rear safety belt
comfort guides in the rear outboard
seating positions. To install:
1. Remove the guide from its
storage pocket on the side of the
seatback.

3-34 Seats and Restraints
{Warning
Never allow a child to wear the
safety belt with the shoulder belt
behind their back. A child can be
seriously injured by not wearing
the lap-shoulder belt properly. In a
crash, the child would not be
restrained by the shoulder belt.
The child could move too far
forward increasing the chance of
head and neck injury. The child
might also slide under the lap(Continued)
Warning (Continued)
belt. The belt force would then be
applied right on the abdomen.
That could cause serious or fatal
injuries. The shoulder belt should
go over the shoulder and across
the chest.
Infants and Young
Children
Everyone in a vehicle needs
protection! This includes infants and
all other children. Neither the
distance traveled nor the age and
size of the traveler changes the
need, for everyone, to use safety
restraints. In fact, the law in every
state in the United States and in
every Canadian province says
children up to some age must be
restrained while in a vehicle.
{Warning
Children can be seriously injured
or strangled if a shoulder belt is
wrapped around their neck. The
shoulder belt can tighten but
cannot be loosened if it is locked.
The shoulder belt locks when it is
pulled all the way out of the
retractor. It unlocks when the
shoulder belt is allowed to go all(Continued)
