Warning (Continued)
Always wear a seat belt, and check
that all passenger(s) are restrained
properly too.
This vehicle has indicators as a
reminder to buckle the seat belts. See
Seat Belt Reminders 097.
Why Seat Belts Work
When riding in a vehicle, you travel as
fast as the vehicle does. If the vehicle
stops suddenly, you keep going until
something stops you. It could be the
windshield, the instrument panel,
or the seat belts! When you wear a seat belt, you and
the vehicle slow down together. There
is more time to stop because you stop
over a longer distance and, when worn
properly, your strongest bones take
the forces from the seat belts. That is
why wearing seat belts makes such
good sense.
Questions and Answers About
Seat Belts
Q: Will I be trapped in the vehicle
after a crash if I am wearing a
seat belt?
A: You could be— whether you are
wearing a seat belt or not. Your
chance of being conscious during
and after a crash, so you can
unbuckle and get out, is much
greater if you are belted.
Q: If my vehicle has airbags, why should I have to wear seat belts?
A: Airbags are supplemental systems
only. They work withseat belts —
not instead of them. Whether or
not an airbag is provided, all
occupants still have to buckle up to
get the most protection. Also, in nearly all states and in all
Canadian provinces, the law
requires wearing seat belts.
Buckle To Drive
If equipped, this feature prevents the
vehicle from shifting out of P (Park)
when the driver seat belt is not
buckled. The Buckle to Drive feature
must be turned ON in the
infotainment system to work. See
Vehicle Personalization
0120 and if
equipped, Teen Driver 0189. If the
engine is running, the driver seat belt
is not buckled, and the brake pedal is
pressed with the vehicle in P (Park), a
message displays in the Driver
Information Center (DIC). Buckle the
driver seat belt to shift out of P (Park).
Shifting from P (Park) will be
prevented once for each ignition cycle.
For some fleet vehicles, the feature is
always ON and it cannot be turned
OFF in the infotainment system.
Shifting from P (Park) will be
prevented each time the above
conditions exist.

SEATS AND RESTRAINTS 53
moderate to severe side collisions,
even belted occupants can contact the
inside of the vehicle.
Airbags supplement the protection
provided by seat belts by distributing
the force of the impact more evenly
over the occupant's body.
Rollover capable roof-rail airbags are
designed to help contain the head and
chest of occupants in the outboard
seating positions in the first and
second rows. The rollover capable
roof-rail airbags are designed to help
reduce the risk of full or partial
ejection in rollover events, although
no system can prevent all such
ejections.
But airbags would not help in many
types of collisions, primarily because
the occupant's motion is not toward
those airbags. SeeWhen Should an
Airbag Inflate? 051.
Airbags should never be regarded as
anything more than a supplement to
seat belts.What Will You See after an
Airbag Inflates?
After frontal, knee, and seat-mounted
side impact airbags inflate, they
quickly deflate, so quickly that some
people may not even realize the
airbags inflated. Roof-rail airbags may
still be at least partially inflated for
some time after they inflate. Some
components of the airbag module may
be hot for several minutes. For
location of the airbags, see Where Are
the Airbags? 050.
The parts of the airbag that come into
contact with you may be warm, but
not too hot to touch. There may be
some smoke and dust coming from
the vents in the deflated airbags.
Airbag inflation does not prevent the
driver from seeing out of the
windshield or being able to steer the
vehicle, nor does it prevent people
from leaving the vehicle.
{Warning
When an airbag inflates, there may
be dust in the air. This dust could
cause breathing problems for
people with a history of asthma or
other breathing trouble. To avoid
this, everyone in the vehicle should
get out as soon as it is safe to do
so. If you have breathing problems
but cannot get out of the vehicle
after an airbag inflates, then get
fresh air by opening a window or a
door. If you experience breathing
problems following an airbag
deployment, you should seek
medical attention.
The vehicle has a feature that may
automatically unlock the doors, turn
on the interior lamps and hazard
warning flashers, and shut off the fuel
system after the airbags inflate. The
feature may also activate, without
airbag inflation, after an event that
exceeds a predetermined threshold.
After turning the ignition off and then
on again, the fuel system will return
to normal operation; the doors can be

Securing a Child Restraint
Designed for the LATCH System
{Warning
A child could be seriously injured or
killed in a crash if the child
restraint is not properly attached to
the vehicle using either the LATCH
anchors or the vehicle seat belt.
Follow the instructions that came
with the child restraint and the
instructions in this manual.
{Warning
To reduce the risk of serious or
fatal injuries during a crash, do not
attach more than one child
restraint to a single anchor.
Attaching more than one child
restraint to a single anchor could
cause the anchor or attachment to
come loose or even break during a
crash. A child or others could be
injured.
{Warning
Children can be seriously injured or
strangled if a shoulder belt is
wrapped around their neck. The
shoulder belt can tighten but
cannot be loosened if it is locked.
The shoulder belt locks when it is
pulled all the way out of the
retractor. It unlocks when the
shoulder belt is allowed to go all
the way back into the retractor, 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.
{Warning
The power seats will work with the
ignition off. Children could operate
the power seats and be injured.
Never leave children alone in the
vehicle.
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.
If you need to secure more than one
child restraint in the rear seat, see
Where to Put the Restraint 065.
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 top tether and
the seat belt. Refer to the child

Uplevel Sport Mode Shown, OtherModes Similar
When the ignition is on, the fuel
gauge indicates the approximate
amount of fuel left in the tank. There is an arrow near the fuel gauge
pointing to the side of the vehicle the
fuel door is on.
When the indicator nears empty, the
low fuel light comes on. There still is
a little fuel left, but the vehicle should
be refueled soon.
The fuel gauge may:
.Take a little more, or less fuel to fill
up than it indicates. For example,
the gauge may have indicated the
tank is half full, but it actually takes
a little more, or less than half the
tank's capacity to fill the tank.
.Move a little while turning a corner,
speeding up, or braking.
.Take a few seconds to stabilize after
the ignition is turned on and goes
back to empty when the ignition is
turned off.
These are normal conditions, none of
which indicate a problem with the fuel
gauge.
Fuel Range
The uplevel instrument cluster has a
estimated fuel range located at the
bottom center of the display. The fuel range is displayed with the
approximate distance the vehicle can
be driven without refueling. The fuel
range estimate is based on an average
of the vehicle’s fuel economy over
recent driving history and the amount
of fuel remaining in the fuel tank.
When the estimated fuel range is low,
the range shows LOW and a message
may also display in the Driver
Information Center (DIC).
