Never wear the shoulder belt under
both arms or behind your back.
Always use the correct buckle for
your seating position.
Never route the lap or shoulder belt
over an armrest.
{Warning
The seat belt can be pinched if it
is routed under plastic trim on the
seat, such as trim around the rear
seatback folding handle or side
airbag. In a crash, pinched seat
belts might not be able to provide
adequate protection. Never allow
seat belts to be routed under
plastic trim pieces.
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 071.
If you are using a rear seating
position with a detachable seat belt,
and the seat belt is not attached,
see Third Row Seats 060 for
instructions on reconnecting the
seat belt to the mini-buckle.
The following instructions explain
how to wear a lap-shoulder belt
properly.

Warning (Continued)
but it cannot do this if it is
wrapped around a child’s neck.
If the shoulder belt is locked and
tightened around a child’s neck,
the only way to loosen the belt is
to cut it.
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.(Continued)
Caution (Continued)
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 you need to secure more than one
child restraint in the rear seat, see
Where to Put the Restraint 092.
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 seat belt and top tether when recommended
by the child restraint
manufacturer. Refer to your
child restraint manufacturer
instructions and the
instructions in this manual. For
the third row outboard seating
positions, if the head restraint
interferes with the proper
installation of the child
restraint, then the head
restraint may be removed. See
“Head Restraint Removal and
Reinstallation under
Lower
Anchors and Tethers for
Children (LATCH System) 093.
1.1. Find the lower anchors for the desired seating
position.
1.2. Put the child restraint on the seat.
1.3. Attach and tighten the lower attachments on the
child restraint to the lower
anchors.

tether around the inboard
or outboard side of the
headrest or head
restraint.
If the position you are
using has a fixed or an
adjustable head restraint
and you are using a dual
tether, route the tether
around the head restraint.
3. Before placing a child in the child restraint, make sure it is
securely held in place. To
check, grasp the child restraint
at the LATCH path and attempt
to move it side to side and
back and forth. There should be no more than 2.5 cm (1 in) of
movement, for proper
installation.

maximum front or rear Gross
Axle Weight Rating (GAWR).
This can cause systems to
break and change the way the
vehicle handles. This could
cause loss of control and a
crash. Overloading can also
reduce stopping distance,
damage the tires, and shorten
the life of the vehicle.
Caution
Overloading the vehicle may
cause damage. Repairs would not
be covered by the vehicle
warranty. Do not overload the
vehicle.
The label will help decide how
much cargo and installed
equipment the truck can carry. Using heavier suspension
components to get added
durability might not change the
weight ratings. Ask your dealer
to help load the vehicle the
right way.
{Warning
Things you put 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. Try to
spread the weight evenly.
.Never stack heavier
things, like suitcases,
inside the vehicle so that
some of them are above
the tops of the seats.
.Do not leave an
unsecured child restraint
in the vehicle.
(Continued)
Warning (Continued)
.When you carry
something inside the
vehicle, secure it
whenever you can.
.Do not leave a seat
folded down unless you
need to.
