.

WARNING: Do not place a
rearward facing child restraint in front of
an active airbag. Failure to follow this
instruction could result in personal injury
or death. WARNING:
Do not attempt to
service, repair, or modify the
supplementary restraint system or
associated components. Failure to
follow this instruction could result in
personal injury or death. WARNING:
Several airbag system
components get hot after inflation. To
reduce the risk of injury, do not touch
them after inflation. WARNING:
If a supplementary
restraint system component has
deployed, it will not function again. Have
the system and associated components
inspected as soon as possible. Failure to
follow this instruction could result in
personal injury or death.
PROPERLY ADJUSTING THE
DRIVER AND FRONT
PASSENGER SEATS WARNING:
National Highway
Traffic Safety Administration (NHTSA)
recommends a minimum distance of at
least
10 in (25 cm) between an
occupant's chest and the driver airbag
module. To properly position yourself away from
the airbag:
•
Move your seat to the rear as far as you
can while still reaching the pedals
comfortably.
• Recline the seat slightly one or two
degrees from the upright position.
After all occupants have adjusted their
seats and put on seatbelts, it is very
important that they continue to sit
properly. Properly seated occupants sit
upright, lean against the seat backrest, and
center themselves on the seat cushion,
with their feet comfortably extended on
the floor. Sitting improperly can increase
the chance of injury in a crash event. For
example, if an occupant slouches, lies
down, turns sideways, sits forward, leans
forward or sideways, or puts one or both
feet up, the chance of injury during a crash
greatly increases.
CHILDREN AND AIRBAGS WARNING:
Do not place a
rearward facing child restraint in front of
an active airbag. Failure to follow this
instruction could result in personal injury
or death. 29

If a person of adult size is sitting in the front
passenger seat, but the passenger airbag
status indicator off lamp is illuminated, it
is possible that the person is not sitting
properly in the seat. If this happens:
•
Switch your vehicle off and ask the
person to place the seat backrest in an
upright position.
• Have the person sit upright in the seat,
centered on the seat cushion, with the
person's legs comfortably extended.
• Restart your vehicle and have the
person remain in this position for about
two minutes. This allows the system
to detect that person and enable the
passenger frontal airbag.
• If the indicator off lamp remains
illuminated even after this, you should
advise the person to ride in the rear
seat.
After all occupants have adjusted their
seats and put on seatbelts, it is very
important that they continue to sit upright,
leaning against the seat backrest, and
centered on the seat cushion, with their
feet comfortably extended on the floor.
Sitting improperly can increase the chance
of injury in a crash event. For example, if
an occupant slouches, lies down, turns
sideways, sits forward, leans forward or
sideways, or puts one or both feet up, the
chance of injury during a crash greatly
increases.
If you think that the state of the passenger
airbag status indicator lamp is incorrect,
check for the following:
• Objects lodged underneath the seat.
• Objects between the seat cushion and
the center console.
• Objects hanging off the seat backrest.
• Objects stowed in the seat backrest
map pocket.
• Objects placed on the occupant's lap. •
Cargo interference with the seat
• Other passengers pushing or pulling on
the seat.
• Rear passenger feet and knees resting
or pushing on the seat.
The listed conditions could cause the
weight of a properly seated occupant to
be incorrectly interpreted by the front
passenger sensing system. The person in
the front passenger seat could appear
heavier or lighter due to the conditions
listed. Make sure the front passenger
sensing system is operating
properly.
If the airbag readiness light is on, do the
following:
• Pull your vehicle over.
• Switch your vehicle off.
• Check for any objects lodged
underneath the front passenger seat
or cargo interfering with the seat.
• Remove the obstruction if found.
• Restart your vehicle.
• Wait at least two minutes and verify
that the airbag readiness light in the
instrument cluster is no longer
illuminated.
• If the airbag readiness light in the
instrument cluster remains illuminated,
there may be a problem due to the
front passenger sensing system.
Do not attempt to repair or service the
system. Take your vehicle in for service
immediately.
If it is necessary to modify an advanced
front airbag system to accommodate a
person with disabilities, contact your
Customer Relationship Center.

The restraints control module also
monitors the readiness of the above safety
devices plus the crash and occupant
sensors. The readiness of the safety
system is indicated by a warning indicator
light in the instrument cluster or by a
backup tone if the warning light is not
working. Routine maintenance of the
airbag is not required.
A difficulty with the system is indicated by
one or more of the following:
The readiness light will not
illuminate immediately after you
switch the ignition on.
• The readiness light either flashes or
stays on.
• You hear a series of five tones. The
tone pattern repeats periodically until
the problem, the light or both are
repaired.
If any of these things happen, even
intermittently, have the supplemental
restraint system serviced immediately.
Unless serviced, the system may not
function properly in the event of a crash.
The fact that the seatbelt pretensioners
or front airbags did not activate for both
front seat occupants in a crash does not
mean that something is wrong with the
system. Rather, it means the restraints
control module determined the accident
conditions (crash severity, seatbelt usage)
were not appropriate to activate these
safety devices.
• The front airbags activate only in
frontal and near-frontal crashes. Front
airbags may activate in rollovers, side
impacts or rear impacts if the crash
causes sufficient frontal deceleration.
• The seatbelt pretensioners activate in
frontal, near-frontal and side crashes,
and in rollovers. •
The side airbags inflate in certain side
impact crashes or rollover events. Side
airbags may activate in other types of
crashes if the vehicle experiences
sufficient sideways motion or
deformation.
• The Safety Canopy inflates in certain
side impact crashes or rollover events.
The Safety Canopy may activate in
other types of crashes if the vehicle
experiences sufficient sideways motion
or deformation, or a certain likelihood
of rollover.
DISPOSING OF AIRBAGS
Contact your authorized dealer as soon as
possible. Airbags must be disposed of by
qualified personnel.

LOCATING THE TIRE LABEL
You will find a Tire Label
containing tire inflation pressure
by tire size and other important
information located on the B-Pillar
or the edge of the driver's door.
DEPARTMENT OF

TIRE QUALITY GRADES
Tire Quality Grades apply to new
pneumatic passenger car tires.
The Quality grades can be found
where applicable on the tire
sidewall between tread shoulder
and maximum section width. For
example: Treadwear 200
Traction AA Temperature A.
These Tire Quality Grades are
determined by standards that the
United States Department of
Transportation has set. Tire Quality Grades apply to new
pneumatic passenger car tires.
They do not apply to deep tread,
winter-type snow tires,
space-saver or temporary use
spare tires, light truck or LT type
tires, tires with nominal rim
diameters of 10 to 12 inches or
limited production tires as defined
in Title 49 Code of Federal
Regulations Part 575.104 (c)(2).
U.S. Department of
Transportation Tire quality
grades:
The U.S. Department of
Transportation requires us to give
you the following information
about tire grades exactly as the
government has written it.
Treadwear
The treadwear grade is a
comparative rating based on the
wear rate of the tire when tested
under controlled conditions on a
specified government test course.
For example, a tire graded 150
would wear 1½ times as well on
the government course as a tire
graded 100. The relative
performance of tires depends
upon the actual conditions of their
use, however, and may depart
significantly from the norm due to
variations in driving habits, service
practices, and differences in road
characteristics and climate.
