Rear Vision Camera (RVC)
The rear vision camera displays a view of the area
behind the vehicle when the vehicle is shifted into
R (Reverse) on the inside rear view mirror or the
navigation screen, if equipped.
To clean the camera lens, located in the bezel for the
tailgate handle, rinse it with water and wipe it with a soft
cloth.
For more information, seeRear Vision Camera (RVC)
on page 3‑45.
Ultrasonic Parking Assist
This feature uses sensors on the rear bumper to detect
objects while parking the vehicle. It 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 3‑43for more information.
Power Outlets
Accessory power outlets can be used to connect
auxiliary electrical equipment, such as a cellular
telephone.
There are two accessory power outlets on the
instrument panel, one inside the center floor console
and one on the rear of the center floor console.
The accessory power outlets are powered, even when
the ignition is in LOCK/OFF. Continuing to use 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

Lap-Shoulder Belt
All seating positions in the vehicle have a lap-shoulder
belt except for the center front passenger position (if
equipped), which has a lap belt. SeeLap Belt
on
page 2‑31for more information.
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 may
affect the passenger sensing system, if equipped.
See Passenger Sensing System
on page 2‑66for
more information. If the belt stops before it reaches the buckle, for
the rear center seating position, tilt the latch plate
and keep pulling the safety belt until it can be
buckled.
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 2‑32.
Position the release button on the buckle so that
the safety belt could be quickly unbuckled if
necessary.
2-25

To make the belt shorter, pull its free end as shown until
the belt is snug.
If the belt is not long enough, seeSafety Belt Extender
on page 2‑32.
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/
retailer 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.

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 and
the safety belt continues to tighten. Never leave
children unattended in a vehicle and never allow
children to play with the safety belts.
Airbags plus lap‐shoulder belts offer protection for
adults and older children, but not for young children and
infants. Neither the vehicle's safety belt system nor its
airbag system is designed for them. Every time infants
and young children ride in vehicles, they should have
the protection provided by appropriate child restraints.
Children who are not restrained properly can strike
other people, or can be thrown out of the vehicle.
{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.
2-36

{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(Continued)
WARNING: (Continued)
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.
2-37

Q: What are the different types of add-on childrestraints?
A: Add-on child restraints, which are purchased by the
vehicle's owner, are available in four basic types.
Selection of a particular restraint should take into
consideration not only the child's weight, height, and
age but also whether or not the restraint will be
compatible with the motor vehicle in which it will
be used.
For most basic types of child restraints, there are
many different models available. When purchasing a
child restraint, be sure it is designed to be used in a
motor vehicle. If it is, the restraint will have a label
saying that it meets federal motor vehicle safety
standards.
The restraint manufacturer's instructions that come
with the restraint state the weight and height
limitations for a particular child restraint. In addition,
there are many kinds of restraints available for
children with special needs.
{WARNING:
To reduce the risk of neck and head injury during
a crash, infants need complete support. This is
because an infant's neck is not fully developed
and its head weighs so much compared with the
rest of its body. In a crash, an infant in a
rear-facing child restraint settles into the restraint,
so the crash forces can be distributed across the
strongest part of an infant's body, the back and
shoulders. Infants should always be secured in
rear-facing child restraints.
2-38

{WARNING:
A young child's hip bones are still so small that
the vehicle's regular safety belt may not remain
low on the hip bones, as it should. Instead, it may
settle up around the child's abdomen. In a crash,
the belt would apply force on a body area that is
unprotected by any bony structure. This alone
could cause serious or fatal injuries. To reduce the
risk of serious or fatal injuries during a crash,
young children should always be secured in
appropriate child restraints.
Child Restraint Systems
A rear-facing infant
seat (A) provides restraint
with the seating surface
against the back of the
infant.
The harness system holds the infant in place and, in a
crash, acts to keep the infant positioned in the restraint.
