Lap-Shoulder Belt
All seating positions in the vehicle have a
lap-shoulder belt.
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 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 can
affect the passenger sensing system, if equipped.
See Passenger Sensing System on page 2‑70.
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 2‑34.
Position the release button on the buckle so that
the safety belt could be quickly unbuckled if
necessary.
4. If equipped with a shoulder belt height adjuster, move it to the height that is right for you. See
“Shoulder Belt Height Adjustment” later in this
section for use and important safety information.

Securing a Child Restraint Designed for the
LATCH System
{WARNING:
If a LATCH-type child restraint is not attached to
anchors, the child restraint will not be able to
protect the child correctly. In a crash, the child
could be seriously injured or killed. Install a
LATCH-type child restraint properly using the
anchors, or use the vehicle's safety belts to
secure the restraint, following the instructions that
came with the child restraint and the instructions
in this manual.
{WARNING:
Do not attach more than one child restraint to a
single anchor. Attaching more than one child
restraint to a single anchor could cause the
anchor or attachment to come loose or even
break during a crash. A child or others could be
injured. To reduce the risk of serious or fatal
injuries during a crash, attach only one child
restraint per anchor.
{WARNING:
Children can be seriously injured or strangled if a
shoulder belt is wrapped around their neck and
the safety belt continues to tighten. Buckle any
unused safety belts behind the child restraint so
children cannot reach them. Pull the shoulder belt
all the way out of the retractor to set the lock,
if your vehicle has one, after the child restraint
has been installed.

If more than one child restraint needs to be installed

Restraint on page 2‑43.

2. Pick up the latch plate, and run the lap and shoulder portions of the vehicle's safety belt
through or around the restraint. The child restraint
instructions will show you how.
3. Push the latch plate into the buckle until it clicks.
Position the release button on the buckle so that
the safety belt could be quickly unbuckled if
necessary.
4. Pull the rest of the shoulder belt all the way out ofthe retractor to set the lock.

Keys
{WARNING:
Leaving children in a vehicle with the ignition key
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 with the keys in the ignition and children
could be seriously injured or killed if caught in the
path of a closing window. Do not leave the keys in
a vehicle with children.
The key can be used for the ignition and the driver's
door lock.
The key has a transponder in the key head that
matches a decoder in the vehicle's steering column.
If a replacement key or any additional keys are needed,
you must purchase it from your dealer/retailer.

Doors and Locks
Door Locks
{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.(Continued)
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
your vehicle. Locking your doors can help
prevent this from happening.
There are several ways to lock and unlock your vehicle.
To lock the driver's door from the outside, turn the key
clockwise. To unlock the door, turn the key
counterclockwise.
You can also use the remote keyless entry transmitter
to lock and unlock the doors.
From the inside, use the manual lock knobs on each
door or the power door lock switch to lock and unlock
all doors.

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.
Driver's Side Shown
The power window controls are located on each of the
side doors. The driver's door also has switches that
control the passenger and rear windows.
Press the switch to lower the window. Pull up on the
front edge of the switch to raise the window.
