iv Preface

You can move the height adjuster
up by pushing up on the shoulder
belt guide.
After the adjuster is set to the desired
position, try to move it down without
pushing the button to make sure it
has locked into position.
Safety Belt Pretensioners
This vehicle has safety belt
pretensioners for the front outboard
occupants. Although the safety belt
pretensioners cannot be seen, they
are part of the safety belt assembly.
They can help tighten the safety belts
during the early stages of a moderate
to severe frontal, near frontal, or rear
crash if the threshold conditions for
pretensioner activation are met. And,
for vehicles with side impact airbags,
safety belt pretensioners can help
tighten the safety belts in a side
crash or a rollover event.Pretensioners work only once. If the
pretensioners activate in a crash,
they will need to be replaced, and
probably other new parts for the
vehicle’s safety belt system. See
Replacing Restraint System Parts
After a Crash on page 1-62.
Rear Safety Belt Comfort
Guides
Rear shoulder belt comfort guides
may provide added safety belt
comfort for older children who have
outgrown booster seats and for
some adults. When installed on a
shoulder belt, the comfort guide
positions the shoulder belt away
from the neck and head.
There is a guide for each
outboard passenger position
in the second row seat and all
passenger positions in the third row.Here is how to install a comfort
guide to the safety belt:
1. For the outboard positions,
remove the guide from its storage
clip on the interior body.
For the third row center position,
locate the comfort guide which
is located in a storage pocket,
at the top of the seat, under
the headrest on the driver’s
side of the vehicle.Outboard Positions

Securing a Child
Restraint in the Right
Front Seat Position
The vehicle has airbags. A rear
seat is a safer place to secure
a forward-facing child restraint.
SeeWhere to Put the Restraint
on page 1-35.
In addition, the vehicle has a
passenger sensing system which is
designed to turn off the right
front passenger frontal airbag and
seat-mounted side impact airbag
under certain conditions. See
Passenger Sensing System on
page 1-55andPassenger Airbag
Status Indicator on page 3-36
for more information, including
important safety information.
A label on the sun visor says,
“Never put a rear-facing child seat
in the front.” This is because the risk
to the rear-facing child is so great,
if the airbag deploys.
{CAUTION
A child in a rear-facing child
restraint can be seriously injured or
killed if the right front passenger
airbag inates. This is because the
back of the rear-facing child
restraint would be very close to the
inating airbag. A child in a
forward-facing child restraint can
be seriously injured or killed if the
right front passenger airbag
inates and the passenger seat is
in a forward position.
Even if the passenger sensing
system has turned off the right
front passenger frontal airbag, no
system is fail-safe. No one can
guarantee that an airbag will not
deploy under some unusual
circumstance, even though it is
turned off.
(Continued)
CAUTION (Continued)
Secure rear-facing child restraints
in a rear seat, even if the airbag is
off. If you secure a forward-facing
child restraint in the right front seat,
always move the front passenger
seat as far back as it will go. It is
better to secure the child restraint
in a rear seat.
SeePassenger Sensing System
on page 1-55for additional
information.
If the child restraint has the LATCH
system, seeLower Anchors and
Tethers for Children (LATCH) on
page 1-37for how and where to
install the child restraint using
LATCH. If a child restraint is secured
using a safety belt and it uses a top
tether, seeLower Anchors and
Tethers for Children (LATCH) on
page 1-37for top tether anchor
locations.
Seats and Restraint System 1-45

In many crashes severe enough to
inate the airbag, windshields
are broken by vehicle deformation.
Additional windshield breakage
may also occur from the right front
passenger airbag.
Airbags are designed to inate
only once. After an airbag
inates, you will need some new
parts for the airbag system. If
you do not get them, the airbag
system will not be there to
help protect you in another crash.
A new system will include
airbag modules and possibly
other parts. The service manual
for your vehicle covers the
need to replace other parts.
The vehicle has a crash sensing
and diagnostic module which
records information after a crash.
SeeVehicle Data Recording
and Privacy on page 7-16
andEvent Data Recorders on
page 7-16.
Let only qualied technicians
work on the airbag systems.
Improper service can mean that
an airbag system will not
work properly. See your
dealer/retailer for service.
Passenger Sensing
System
The vehicle has a passenger
sensing system for the right front
passenger position. The passenger
airbag status indicator will be
visible on the instrument panel when
the vehicle is started.The words ON and OFF, or the
symbol for on and off, are visible
during the system check. If you are
using remote start, if equipped,
to start the vehicle from a distance,
you may not see the system
check. When the system check is
complete, either the word ON
or OFF, or the symbol for on or off,
will be visible. SeePassenger
Airbag Status Indicator on
page 3-36.
The passenger sensing system turns
off the right front passenger frontal
airbag under certain conditions. The
driver airbag, seat-mounted side
impact airbags and the roof-rail
airbags are not affected by the
passenger sensing system.
The passenger sensing system
works with sensors that are part of
the right front passenger seat. The
sensors are designed to detect the
presence of a properly-seated
occupant and determine if the right
front passenger frontal airbag should
be enabled (may inate) or not. United States

The following describes how the URPA display lights appear as the vehicle
gets closer to a detected object:
DescriptionEnglishMetric
amber light 8 ft2.5 m
amber/amber lights 40 in1.0 m
amber/amber/red lights 23 in0.6 m
amber/amber/red lights ashing 1 ft 0.3 m
The system can be disabled through
the Driver Information Center
(DIC). See “Park Assist” under DIC
Operation and Displays (With
DIC Buttons) on page 3-46 orDIC
Operation and Displays (Without
DIC Buttons) on page 3-51 for more
information.
When the System Does Not
Seem to Work Properly
If the URPA system will not activate
due to a temporary condition, the
message PARK ASSIST OFF will be
displayed on the DIC and a red
light will be shown on the rear URPA display when the shift lever is
moved into R (Reverse). This may
occur under the following
conditions:
The driver disables the system.
The parking brake pedal is
depressed.
The ultrasonic sensors are not
clean. Keep the vehicle’s rear
bumper free of mud, dirt,
snow, ice and slush. For cleaning
instructions, see
Washing Your
Vehicle on page 5-84 .
A trailer was attached to the
vehicle, or a bicycle or an
object was hanging out of the
liftgate during the last drive cycle,
the red light may illuminate in
the rear display. Once the
attached object is removed,
URPA will return to normal
operation.
A tow bar is attached to the
vehicle.
The vehicle’s bumper is
damaged. Take the vehicle to
your dealer/retailer to repair
the system.
Other conditions may affect
system performance, such
as vibrations from a jackhammer
or the compression of air
brakes on a very large truck.
If the system is still disabled, after
driving forward at least 15 mph
(25 km/h), take the vehicle to your
dealer/retailer.
2-36 Features and Controls

A fast ash may indicate that the
display has been on for the
maximum allowable time during a
reverse cycle, or the display
has reached an Over
Temperature limit.
The fast ash conditions are
used to protect the video device
from high temperature
conditions. Once conditions
return to normal the device will
reset and the green indicator will
stop ashing.
During any of these fault conditions,
the display will be blank and the
indicator will continue to ash as long
as the vehicle is in R (Reverse) or
until the conditions return to normal.
Briey pressing
zwhen the left
indicator light is ashing will turn off
the video display along with the
left indicator light.
