Tire Pressure Monitor
This vehicle may have a Tire Pressure Monitor
System (TPMS).
The Tire Pressure Monitor
alerts you when a
significant reduction in
pressure occurs in one or
more of the vehicle’s tires
by illuminating the low tire
pressure warning light on
the instrument cluster.
The warning light will remain on until the tire pressure is
corrected. The proper tire pressures for your vehicle are
listed on the Tire and Loading Information label located
on the driver side center pillar (B pillar). See Loading
the Vehicle
on page 5‑31.
You may notice during cooler conditions that the low tire
pressure warning light will appear when the vehicle is
first started and then turn off as you drive. This may be
an early indicator that your tire pressures are getting
low and the tires need to be inflated to the proper
pressure.

The OnStar system can record and transmit vehicle
information. This information is automatically sent to an
OnStar call center when
Qis pressed,]is pressed,
or if the airbags or ACR system deploy. This information
usually includes the vehicle's GPS location and, in the
event of a crash, additional information regarding the
crash that the vehicle was involved in (e.g. the direction
from which the vehicle was hit). When the virtual
advisor feature of OnStar hands-free calling is used,
the vehicle also sends OnStar the vehicle's GPS
location so they can provide services where it is
located.
Location information about the vehicle is only available
if the GPS satellite signals are unobstructed and
available.
The vehicle must have a working electrical system,
including adequate battery power, for the OnStar
equipment to operate. There are other problems OnStar
cannot control that may prevent OnStar from providing
OnStar service at any particular time or place. Some
examples are damage to important parts of the vehicle
in a crash, hills, tall buildings, tunnels, weather or
wireless phone network congestion.
OnStar Steering Wheel Controls
This vehicle may have a Talk/Mute button that can
be used to interact with OnStar hands-free calling.
See Audio Steering Wheel Controls
on page 4‑132for
more information.
On some vehicles, the mute button can be used to dial
numbers into voice mail systems, or to dial phone
extensions. See the OnStar Owner's Guide for more
information.
Your Responsibility
Increase the volume of the radio if the OnStar advisor
cannot be heard.
If the light next to the OnStar buttons is red, the system
may not be functioning properly. Press
Qand request a
vehicle diagnostic. If the light appears clear (no light is
appearing), your OnStar subscription has expired and
all services have been deactivated. Press
Qto confirm
that the OnStar equipment is active.

Folding and Tumbling the Second Row
Seat(s) from the Third Row Seats or
Outside
{WARNING:
Using the third row seating position while the
second row is folded, or folded and tumbled, could
cause injury in a sudden stop or crash. Be sure to
return the seat to the passenger seating position.
Push and pull on the seat to make sure it is
locked into place.
To fold and tumble the seat from the third row seats,
if your vehicle has them: 1. Make sure that there is nothing under, in front of, or on the seat.
Notice: Folding a rear seat with the safety belts still
fastened may cause damage to the seat or the
safety belts. Always unbuckle the safety belts and
return them to their normal stowed position before
folding a rear seat.

vehicle.
Installing the Third Row Seat
To install the seat, do the following:
1. Open the liftgate to access the rear of the vehicle.
2. Slide the front outboard seat wheels into the track on the floor and roll the seat forward. The front
latches should lock into place. If the latches do not

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
on
page 2‑47for more information.
The lap‐shoulder belts for the first and second row
seating positions are equipped with free‐falling latch
plates. If the vehicle has a third row, the lap‐shoulder
belts have either free‐falling or cinching latch plates.
Use the following pictures to determine the latch
plate style:
Free-Falling Latch Plate
Cinching Latch Plate
The following instructions explain how to wear a
lap-shoulder belt properly. 1. Adjust the seat, if the seat is adjustable, so you can sit up straight. To see how, see “Seats”in
the Index.
2. Pick up the latch plate and pull the belt across you. Do not let it get twisted.
The lap-shoulder belt may lock if you pull the belt
across you very quickly. If this happens, let the belt
go back slightly to unlock it. Then pull the belt
across you more slowly.

6. To tighten the belt, push down on the childrestraint, pull the shoulder portion of the belt to
tighten the lap portion of the belt and feed the
shoulder belt back into the retractor. When
installing a forward-facing child restraint, it may be
helpful to use your knee to push down on the child
restraint as you tighten the belt.
7. Push and pull the child restraint in different directions to be sure it is secure. If the vehicle is equipped with the passenger sensing
system, and when the passenger sensing system has
turned off the right front passenger frontal airbag, the
off indicator in the passenger airbag status indicator
should light and stay lit when you start the vehicle.
See
Passenger Airbag Status Indicator on page 4‑29.
If a child restraint has been installed and the on
indicator is lit, see “If the On Indicator is Lit for a Child
Restraint” underPassenger Sensing System
on
page 2‑85for more information.
To remove the child restraint, unbuckle the vehicle
safety belt and let it return to the stowed position.

{WARNING:
Children who are up against, or very close to,
any airbag when it inflates can be seriously
injured or killed. Airbags plus lap-shoulder belts
offer protection for adults and older children, but
not for young children and infants. Neither the
vehicle's safety belt system nor its airbag system
is designed for them. Young children and infants
need the protection that a child restraint system
can provide. Always secure children properly in
your vehicle. To read how, seeOlder Children
on
page 2‑49
or Infants and Young Childrenon
page 2‑52
.
There is an airbag
readiness light on the
instrument panel cluster,
which shows the airbag
symbol.
The system checks the airbag electrical system for
malfunctions. The light tells you if there is an electrical
problem. See Airbag Readiness Light
on page 4‑28for
more information.
