Ultrasonic Parking Assist
This feature uses sensors on the rear bumper to
detect objects while parking the vehicle. URPA comes
on automatically when the shift lever is moved into
R (Reverse) and operates at speeds less than 8 km/h
(5 mph). URPA uses audio beeps to provide distance
and system information.
Keep the sensors on the vehicle's rear bumper clean to
ensure proper operation.
The system can be disabled by pressing the rear park
aid disable button located next to the radio.
SeeUltrasonic Rear Parking Assist (URPA)
on
page 3‑58for more information.
Power Outlets
Accessory power outlets can be used to connect
auxiliary electrical equipment, such as a cellular
telephone.
There are two under the climate controls, one inside the
center floor console, one on the rear of the center floor
console and one accessory power outlet in the rear
cargo area on the passenger side. The accessory power outlets are powered, even with
the ignition off. Continuing to use accessory power
outlets while the ignition is in LOCK/OFF may cause
the vehicle's battery to run down.
Universal Remote System
The Universal Home Remote System allows for garage
door openers, security systems, and home automation
devices to be programmed to work with these buttons in
the vehicle.

4. Push and pull on the seat to make sure it is lockedinto place. The seatback cannot be raised to the
upright position unless the seat is secured to the
floor.
5. Pull up on the seatback until it locks into the upright position.
{WARNING:
If either seatback is not locked, it could move
forward in a sudden stop or crash. That could
cause injury to the person sitting there. Always
push and pull on the seatbacks to be sure they
are locked.
6. Push and pull on the seatback to make sure it is locked.
{WARNING:
A safety belt that is improperly routed, not
properly attached, or twisted will not provide the
protection needed in a crash. The person wearing
the belt could be seriously injured. After raising
the rear seatback, always check to be sure that
the safety belts are properly routed and attached,
and are not twisted.
7. Make sure the safety belts are returned to the original position over the seatbacks.

3. Push the latch plate into the buckle until it clicks.If you find that the latch plate will not go fully into
the buckle, see if you are using the correct buckle.
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 2‑55.
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 instructions on use and important
safety information.5. To make the lap part tight, pull up on the shoulder belt.
It may be necessary to pull stitching on the safety
belt through the latch plate to fully tighten the lap
belt on smaller occupants.

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.
Child Restraints
Older Children
Older children who have outgrown booster seats should
wear the vehicle's safety belts.

{WARNING:
Never do this.
Never hold an infant or a child while riding in a
vehicle. Due to crash forces, an infant or a child
will become so heavy it is not possible to hold it
during a crash. For example, in a crash at only
40 km/h (25 mph), a 5.5 kg (12 lb) infant will
suddenly become a 110 kg (240 lb) force on a
person's arms. An infant should be secured in
an appropriate restraint.
2-60

{WARNING:
Never do this.
Children who are up against, or very close to, any
airbag when it inflates can be seriously injured or
killed. Never put a rear-facing child restraint in
the right front seat. Secure a rear-facing child
restraint in a rear seat. It is also better to secure a
forward-facing child restraint in a rear seat. If you
must secure a forward-facing child restraint in the
right front seat, always move the front passenger
seat as far back as it will go.
