where the child restraint will be
placed.Second Row Seat —60/40
For models with 60/40 second row
seating, the top tether anchors are
at the bottom rear of the seat

{Caution
Do not let the LATCH
attachments rub against the
vehicle’s safety belts. This may
damage these parts. If necessary,
move buckled safety belts to
avoid rubbing the LATCH
attachments.
Do not fold the empty rear seat
with a safety belt buckled. This
could damage the safety belt or
the seat. Unbuckle and return the
safety belt to its stowed position,
before folding the seat.
The vehicle may be 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 on
page 3-50. This system is designed to make
installation of child restraints easier.
When using lower anchors, do not
use the vehicle's safety belts.
Instead use the vehicle's anchors
and child restraint attachments to
secure the restraints. Some
restraints also use another vehicle
anchor to secure a top tether.
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 the safety belts
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 “HeadRestraint Removal and
Reinstallation under
Lower
Anchors and Tethers for
Children (LATCH System) on
page 3-51.
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.
2. If the child restraint manufacturer recommends that the top tether
be attached, attach and tighten
the top tether to the top tether
anchor. Refer to the child
restraint instructions and the
following steps:
2.1. Find the top tether anchor.
For models with a third row
seat, move the flipper panel
rearward to access the top
tether anchors.

voltmeter gauge may also read
lower when in fuel economy mode.
This is normal.
Readings outside the normal
operating range can also occur
when a large number of electrical
accessories are operating in the
vehicle and the engine is left idling
for an extended period. This
condition is normal since the
charging system is not able to
provide full power at engine idle. As
engine speeds are increased, this
condition should correct itself as
higher engine speeds allow the
charging system to create maximum
power.
The vehicle can only be driven for a
short time with the readings outside
the normal operating range. If the
vehicle must be driven, turn off all
accessories, such as the radio and
air conditioner.Readings outside the normal
operating range indicate a possible
problem in the electrical system.
Have the vehicle serviced as soon
as possible.
