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.

located at the rear of
the seat, rearward.
4. Roll the seat out of the vehicle. There is a track in the floor to guide the seat wheels out of the
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
lock, try tilting the rear of the seat upward slightly. 3. Lower the rear of the seat and push down on the
seat to engage the rear floor latches.
{WARNING:
A seat that is not locked into place properly can
move around in a collision or sudden stop. People
in the vehicle could be injured. Be sure to lock the
seat into place properly when installing it.
4. Push and pull on the seat to make sure it is locked into place. The seatback cannot be raised to the
upright position unless the seat is secured to the
floor.
5. Pull up on the seatback until it locks into the upright position.
2-25

{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.
2-77

{WARNING:
A child in a rear-facing child restraint can be
seriously injured or killed if the right front
passenger airbag inflates. This is because the
back of the rear-facing child restraint would be
very close to the inflating airbag. A child in a
forward-facing child restraint can be seriously
injured or killed if the right front passenger airbag
inflates 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 the airbag is
turned off.
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.The passenger sensing system is designed to turn off
the right front passenger frontal airbag if:
.The right front passenger seat is unoccupied.
.The system determines an infant is present in a
child restraint.
.A right front passenger takes his/her weight off of
the seat for a period of time.
.Or, if there is a critical problem with the airbag
system or the passenger sensing system.
When the passenger sensing system has turned off the
right front passenger frontal airbag, the off indicator will
light and stay lit to remind you that the airbag is off. See
Passenger Airbag Status Indicator on page 4‑29.
The passenger sensing system is designed to turn on
(may inflate) the right front passenger frontal airbag
anytime the system senses that a person of adult size
is sitting properly in the right front passenger seat.
When the passenger sensing system has allowed the
airbag to be enabled, the on indicator will light and stay
lit to remind you that the airbag is active.
2-87

For some children, including children in child restraints,
and for very small adults, the passenger sensing
system may or may not turn off the right front passenger
frontal airbag, depending upon the person's seating
posture and body build. Everyone in your vehicle who
has outgrown child restraints should wear a safety belt
properly—whether or not there is an airbag for that
person.
{WARNING:
If the airbag readiness light ever comes on and
stays on, it means that something may be wrong
with the airbag system. To help avoid injury to
yourself or others, have the vehicle serviced right
away. See Airbag Readiness Light
on page 4‑28
for more information, including important safety
information.
If the On Indicator is Lit for a Child
Restraint
If a child restraint has been installed and the on
indicator is lit:
1. Turn the vehicle off.
2. Remove the child restraint from the vehicle. 3. Remove any additional items from the seat such as
blankets, cushions, seat covers, seat heaters,
or seat massagers.
4. Reinstall the child restraint following the directions provided by the child restraint manufacturer and
refer to Securing a Child Restraint in the Right
Front Seat Position on page 2‑71.
5. If, after reinstalling the child restraint and restarting the vehicle, the on indicator is still lit, turn the
vehicle off. Then slightly recline the vehicle
seatback and adjust the seat cushion, if adjustable,
to make sure that the vehicle seatback is not
pushing the child restraint into the seat cushion.
Also make sure the child restraint is not trapped
under the vehicle head restraint. If this happens,
adjust the head restraint. See Head Restraints
on
page 2‑2.
6. Restart the vehicle. The passenger sensing system may or may not
turn off the airbag for a child in a child restraint
depending upon the child’s seating posture and
body build. It is better to secure the child restraint
in a rear seat.

Replacing Restraint System Parts
After a Crash
{WARNING:
A crash can damage the restraint systems in your
vehicle. A damaged restraint system may not
properly protect the person using it, resulting in
serious injury or even death in a crash. To help
make sure your restraint systems are working
properly after a crash, have them inspected and
any necessary replacements made as soon as
possible.
If the vehicle has been in a crash, do you need new
safety belts or LATCH system (if equipped) parts?
After a very minor crash, nothing may be necessary. But
the safety belt assemblies that were used during any
crash may have been stressed or damaged. See your
dealer/retailer to have the safety belt assemblies
inspected or replaced. If the vehicle has the LATCH system and it was being
used during a crash, you may need new LATCH
system parts.
New parts and repairs may be necessary even if the
safety belt or LATCH system (if equipped), was not
being used at the time of the crash.
If an airbag inflates, you will need to replace airbag
system parts. See the part on the airbag system earlier
in this section.
Have the safety belt pretensioners checked if the
vehicle has been in a crash, if the airbag readiness light
stays on after the vehicle is started, or while you are
driving. See
Airbag Readiness Light
on page 4‑28.
