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
Leaving children in a vehicle with
the keys is dangerous for many
reasons. Children or others could
be badly injured or even killed.
They could operate the power
windows or other controls or even
make the vehicle move. The
windows will function and they
could be seriously injured or killed
if caught in the path of a closing
window. Do not leave keys in a
vehicle with children.
When there are children in the
rear seat use the window lockout
button to prevent unintentional
operation of the windows.
The power window switches are
located on each of the side doors.
The driver door also has switches
that control the front passenger and
rear windows. The power windows
work when the ignition is in ON/
RUN or ACC/ACCESSORY, or in
Retained Accessory Power (RAP).
SeeRetained Accessory Power
(RAP) on page 9‑27.
Press the switch to lower the
window. Pull up the front of the
switch to raise the window.

Questions and Answers About
Safety Belts
Q: Will I be trapped in the vehicleafter a crash if I am wearing a
safety belt?
A: You could be—whether you are
wearing a safety belt or not.
Your chance of being conscious
during and after a crash, so you
can unbuckle and get out, is
much greater if you are belted.
Q: If my vehicle has airbags, why should I have to wear safety
belts?
A: Airbags are supplemental
systems only; so they work with
safety belts —not instead of
them. Whether or not an airbag
is provided, all occupants still
have to buckle up to get the
most protection. Also, in nearly all states and in
all Canadian provinces, the law
requires wearing safety belts.
How to Wear Safety Belts
Properly
This section is only for people of
adult size.
There are special things to know
about safety belts and children. And
there are different rules for smaller
children and infants. If a child will be
riding in the vehicle, see
Older
Children on page 3‑45 orInfants
and Young Children on page 3‑47.
Follow those rules for everyone's
protection.
It is very important for all occupants
to buckle up. Statistics show that
unbelted people are hurt more often
in crashes than those who are
wearing safety belts.
There are important things to know
about wearing a safety belt properly.
.Sit up straight and always keep
your feet on the floor in front
of you.
.Always use the correct buckle
for your seating position.
.Wear the lap part of the belt low
and snug on the hips, just
touching the thighs. In a crash,
this applies force to the strong
pelvic bones and you would be
less likely to slide under the lap
belt. If you slid under it, the belt
would apply force on your
abdomen. This could cause
serious or even fatal injuries.

Cinching Latch Plate
The following instructions explain
how to wear a lap-shoulder belt
properly.
1. Adjust the seat, if the seat is adjustable, so you can sit up
straight. To see how, see “Seats”
in the Index. 2. Pick up the latch plate and pull
the 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 with a free‐falling
latch plate 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.
Engaging the child restraint
locking feature in the right front
seating position may affect the
passenger sensing system,
if equipped. See Passenger
Sensing System on page 3‑38
for more information.If the belt stops before it reaches
the buckle, for lap‐shoulder belts
with cinching latch plates, tilt the
latch plate and keep pulling the
safety belt until it can be
buckled.

Squeeze the buttons (A) on the
sides of the height adjuster and
move the height adjuster to the
desired position.
The adjuster can be moved up just
by pushing up on the shoulder belt
guide.
After the adjuster is set to the
desired position, try to move it down
without squeezing the buttons to
make sure it has locked into
position.
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. And, if the
vehicle has side impact airbags,
safety belt pretensioners can help
tighten the safety belts in a side
crash or a rollover event.
Pretensioners work only once. If the
pretensioners activate in a crash,
the pretensioners and probably
other parts of the vehicle's safety
belt system will need to be replaced.
SeeReplacing Safety Belt System
Parts after a Crash on page 3‑29.
Rear Safety Belt Comfort
Guides
This vehicle may have rear shoulder
belt comfort guides. If not, they are
available through your dealer. The
guides may provide added safety
belt comfort for older children who
have outgrown booster seats and
for some adults. When installed and
properly adjusted, the comfort guide
positions the belt away from the
neck and head.
There is one guide, if equipped, for
each outside passenger position in
the second row seat.

Lap Belt
This part is only for the lap belt. To
learn how to wear a lap-shoulder
belt, seeLap-Shoulder Belt on
page 3‑22.
The vehicle may have a center
seating position. When you sit in the
center front seating position, you
have a lap safety belt, which has no
retractor.
To make the belt longer, tilt the latch
plate and pull it along the belt. Buckle, position and release it the
same way as the lap part of a
lap-shoulder belt.
To make the belt shorter, pull its free
end as shown until the belt is snug.
If the belt is not long enough, see
Safety Belt Extender on page 3‑28.
Make sure the release button on the
buckle is positioned so you would
be able to unbuckle the safety belt
quickly if necessary.
If you find that the latch plate will
not go fully into the buckle, see if
you are using the correct buckle. Be
sure that the latch plate clicks when
inserted into the buckle.
Safety Belt Extender
If the vehicle's safety belt will fasten
around you, you should use it.
But if a safety belt is not long
enough, your dealer will order you
an extender. When you go in to
order it, take the heaviest coat you
will wear, so the extender will be
long enough for you. To help avoid
personal injury, do not let someone
else use it, and use it only for the
seat it is made to fit. The extender
has been designed for adults. Never
use it for securing child seats. To
wear it, attach it to the regular safety
belt. For more information, see the
instruction sheet that comes with
the extender.
