76 Seats and Restraints
Warning (Continued)
Buckle any unused seat 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, and
tighten the belt behind the child restraint
after the child restraint has been
installed.
Caution
Do not let the LATCH attachments rub
against the vehicle’s seat belts. This may
damage these parts. If necessary, move
buckled seat belts to avoid rubbing the
LATCH attachments.
Do not fold the rear seatback when the
seat is occupied. Do not fold the empty
rear seat with a seat belt buckled. This
could damage the seat belt or the seat.
Unbuckle and return the seat belt to its
stowed position, before folding the seat.
The vehicle is equipped with a front center
airbag in the inboard side of the driver seat.
Even with a front center airbag, a child
restraint can be installed in any second row
seating position. If a child restraint is installed in a second row center seat, move
the second row seat to the rearward
position, whenever possible, to minimize
contact with the front center airbag.
If you need to secure more than one child
restraint in the rear seat, see
Where to Put
the Restraint 069.
1. Attach and tighten the lower attachments to the lower anchors. If the
child restraint does not have lower
attachments or the desired seating
position does not have lower anchors,
secure the child restraint with the top
tether and the seat belt. Refer to the
child restraint manufacturer instructions
and the instructions in this manual.
1.1. Find the lower anchors for the desired seating position.

upright before placing the child
restraint on the seat.
1.3. Put the child restraint on the seat.
1.4. Attach and tighten the lower attachments on the child restraint
to the lower anchors. If necessary, adjust the angle of the
second row seatback to achieve a
tight installation. Make sure the
second row bench seatbacks are
aligned at the same angle.
2. If the child restraint manufacturer recommends that the top tether be
attached, attach and tighten the top
tether to the top tether anchor, if the
vehicle has one. Refer to the child
restraint instructions and the following
steps:
2.1. Find the top tether anchor.
2.2. Route, attach, and tighten the top tether according to your child
restraint instructions and the

212 Driving and Operating
Certification/Tire Label
Label Example
A vehicle-specific Certification/Tire label
is attached to the center pillar (B-pillar).
The label may show the size of the
vehicle's original tires and the inflation
pressures needed to obtain the gross
weight capacity of the vehicle. The label
shows the gross weight capacity of the
vehicle. This is called the Gross Vehicle
Weight Rating (GVWR). The GVWR
includes the weight of the vehicle, all
occupants, fuel, and cargo.The Certification/Tire label may also
show the maximum weights for the
front and rear axles, called the Gross
Axle Weight Rating (GAWR). To find out
the actual loads on the front and rear
axles, weigh the vehicle at a weigh
station. Your dealer can help with this.
Be sure to spread the load equally on
both sides of the centerline.
Caution
Overloading the vehicle may cause
damage. Repairs would not be covered by
the vehicle warranty. Do not overload the
vehicle.
{Warning
Things inside the vehicle can strike
and injure people in a sudden stop or
turn, or in a crash.
.Put things in the cargo area of the
vehicle. In the cargo area, put
them as far forward as possible.
Try to spread the weight evenly.
(Continued)

suitcases, inside the vehicle so

.Do not leave an unsecured child
restraint in the vehicle.
.Secure loose items in the vehicle.
.Do not leave a seat folded down
unless needed.

full-throttle starts. Avoid downshifting
to brake or slow the vehicle.
