Section 1 Seats and Restraint System
1-1

Head Restraints
The vehicle’s front seats have adjustable head restraints
in the outboard seating positions.
{CAUTION:
With head restraints that are not installed and
adjusted properly, there is a greater chance that
occupants will suffer a neck/spinal injury in a
crash. Do not drive until the head restraints for all
occupants are installed and adjusted properly.
Adjust the head restraint so that the top of the restraint
is at the same height as the top of the occupant’s
head. This position reduces the chance of a neck injury
in a crash.
1-2

Pull the head restraint up to raise it. To lower the head
restraint, press the button, located on the top of the
seatback, and push the restraint down.
Push down on the head restraint after the button is
released to make sure that it is locked in place.
The head restraints are not designed to be removed.

Driver’s Seat with Power Seat Control, Power
Recline, and Power Lumbar shown
1-10

{CAUTION:
Sitting in a reclined position when your vehicle is
in motion can be dangerous. Even if you buckle
up, your safety belts cannot do their job when you
are reclined like this.
The shoulder belt cannot do its job. In a crash, you
could go into it, receiving neck or other injuries.
The lap belt cannot do its job either. In a crash the
belt could go up over your abdomen. The belt
forces would be there, not at your pelvic bones.
This could cause serious internal injuries.
For proper protection when the vehicle is in motion,
have the seatback upright. Then sit well back in the
seat and wear your safety belt properly.
Do not have the seatback reclined if your vehicle is
moving.
1-11

Center Seat
Your vehicle may have a front center seat. This seat can
be converted to a storage area by lowering the seatback.
See Center Flex Storage Unit on page 2-57.
Rear Seats
Rear Seat Pass-Through Door
Your vehicle has a pass-through door that provides
access to the trunk from the rear seats. See “Rear Seat
Pass-Through Door” under Trunk on page 2-13.
Safety Belts
Safety Belts: They Are for Everyone
This section of the manual describes how to use
safety belts properly. It also describes some things not
to do with safety belts.
1-12

{CAUTION:
Do not let anyone ride where a safety belt cannot
be worn properly. In a crash, if you or your
passenger(s) are not wearing safety belts, the
injuries can be much worse. You can hit things
inside the vehicle harder or be ejected from the
vehicle. You and your passenger(s) can be
seriously injured or killed. In the same crash, you
might not be, if you are buckled up. Always fasten
your safety belt, and check that your passenger(s)
are restrained properly too.
{CAUTION:
It is extremely dangerous to ride in a cargo area,
inside or outside of a vehicle. In a collision, people
riding in these areas are more likely to be seriously
injured or killed. Do not allow people to ride in any
area of your vehicle that is not equipped with seats
and safety belts. Be sure everyone in your vehicle is
in a seat and using a safety belt properly.
This vehicle has indicators as a reminder to buckle the
safety belts. See Safety Belt Reminders on page 3-35
for additional information.
1-13

In most states and in all Canadian provinces, the law
requires wearing safety belts. Here is why:
You never know if you will be in a crash. If you do have
a crash, you do not know if it will be a serious one.
A few crashes are mild, and some crashes can be so
serious that even buckled up, a person would not survive.
But most crashes are in between. In many of them,
people who buckle up can survive and sometimes walk
away. Without safety belts, they could have been badly
hurt or killed.
After more than 40 years of safety belts in vehicles,
the facts are clear. In most crashes buckling up does
matter... a lot!
Why Safety Belts Work
When you ride in or on anything, you go as fast as
it goes.
Take the simplest vehicle. Suppose it is just a seat on
wheels.
1-14

Put someone on it. Get it up to speed. Then stop the vehicle. The rider
does not stop.
1-15

The person keeps going until stopped by something.
In a real vehicle, it could be the windshield... or the instrument panel...
