safety belt nine times, ending in the unbuckled state. (Step 3 must be
completed within 50 seconds after the safety belt warning light turns
off.)
•After Step 3, the restraint system warning light (airbag light) will be
turned on for three seconds.
4. Within approximately seven seconds of the light turning off, buckle
then unbuckle the safety belt.
•This will disable the Belt-Minderfeature for that seating position if it
is currently enabled. As confirmation, the restraint system warning
light will flash four times per second for three seconds.
•This will enable the Belt-Minderfeature for that seating position if it
is currently disabled. As confirmation, the restraint system warning
light will flash four times per second for three seconds, followed by
three seconds with the light off, then followed by the restraint system
warning light flashing four times per second for three seconds again.
Safety belt extension assembly
If the safety belt is too short when fully extended, there is a 8 inch
(20 cm) safety belt extension assembly that can be added (part number
611C22). This assembly can be obtained from an authorized dealer.
Use only extensions manufactured by the same supplier as the safety
belt. Manufacturer identification is located at the end of the webbing on
the label. Also, use the safety belt extension only if the safety belt is too
short for you when fully extended.

SAFETY RESTRAINTS FOR CHILDREN
See the following sections for directions on how to properly use safety
restraints for children. Also seeAirbag supplemental restraint system
(SRS)in this chapter for special instructions about using airbags.
Important child restraint precautions
You are required by law to use safety restraints for children in the U.S.
and Canada. If small children (generally children who are four years old
or younger and who weigh 40 lb. [18 kg] or less) ride in your vehicle, you
must put them in safety seats made especially for children. Many states
require that children use approved booster seats until they are eight
years old. Check your local and state or provincial laws for specific
requirements regarding the safety of children in your vehicle. When
possible, always place children under age 12 in the rear seat of your
vehicle. Accident statistics suggest that children are safer when properly
restrained in the rear seating positions than in the front seating position.
Never let a passenger hold a child on his or her lap while the
vehicle is moving. The passenger cannot protect the child from
injury in a collision.
Always follow the instructions and warnings that come with any infant or
child restraint you might use.
Children and safety belts
If the child is the proper size, restrain the child in a safety seat. Children
who are too large for child safety seats (as specified by your child safety
seat manufacturer) should always wear safety belts.
Follow all the important safety restraint and airbag precautions that
apply to adult passengers in your vehicle.
If the shoulder belt portion of a combination lap and shoulder belt can
be positioned so it does not cross or rest in front of the child’s face or
neck, the child should wear the lap and shoulder belt. Moving the child
closer to the center of the vehicle may help provide a good shoulder belt
fit.
Do not leave children, unreliable adults, or pets unattended in
your vehicle.

Sometimes irregular tire wear can be corrected by rotating the tires.
Note:If your tires show uneven wear ask an authorized dealer to check
for and correct any wheel misalignment, tire imbalance or mechanical
problem involved before tire rotation.
Note:Your vehicle may be equipped with a dissimilar spare tire/wheel. A
dissimilar spare tire/wheel is defined as a spare tire and/or wheel that is
different in brand, size or appearance from the road tires and wheels. If
you have a dissimilar spare tire/wheel it is intended for temporary use
only and should not be used in a tire rotation.
Note:After having your tires rotated, inflation pressure must be checked
and adjusted to the vehicle requirements.
If the tire label shows different tire pressures for the front and
rear tires and the vehicle is equipped with TPMS (tire pressure
monitoring system), then the settings for the TPMS sensors need to be
updated. Always perform the TPMS reset procedure after tire rotation.
If the system is not reset, it may not provide a low tire pressure
warning when necessary. See the TPMS reset procedure in this
chapter.

10.Tire Ply Composition and Material Used:Indicates the number of
plies or the number of layers of rubber-coated fabric in the tire tread and
sidewall. Tire manufacturers also must indicate the ply materials in the
tire and the sidewall, which include steel, nylon, polyester, and others.
11.Maximum Load:Indicates the maximum load in kilograms and
pounds that can be carried by the tire. Refer to the Safety Compliance
Certification Label, which is located on the B-Pillar or the edge of the
driver’s door, for the correct tire pressure for your vehicle.
12.Treadwear, Traction and Temperature Grades
•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 one and one-half (1
1⁄2) times as well on the government
course as a tire graded 100.
•Traction:The traction grades, from highest to lowest are AA, A, B,
and C. The grades represent the tire’s ability to stop on wet pavement
as measured under controlled conditions on specified government test
surfaces of asphalt and concrete. A tire marked C may have poor
traction performance.
•Temperature:The temperature grades are A (the highest), B and C,
representing the tire’s resistance to the generation of heat and its
ability to dissipate heat when tested under controlled conditions on a
specified indoor laboratory test wheel.
13.Maximum Permissible Inflation Pressure:Indicates the tire
manufacturers’ maximum permissible pressure and/or the pressure at
which the maximum load can be carried by the tire. This pressure is
normally higher than the manufacturer’s recommended cold inflation
pressure which can be found on the Safety Compliance Certification
Label or Tire Label which is located on the B-Pillar or the edge of the
driver’s door. The cold inflation pressure should never be set lower than
the recommended pressure on the vehicle label.
The tire suppliers may have additional markings, notes or warnings such
as standard load, radial tubeless, etc.

following two conditions: (1) This device may not cause harmful
interference, and (2) This device must accept any interference received,
including interference that may cause undesired operation.
The Tire Pressure Monitoring System is NOT a substitute for
manually checking tire pressure. The tire pressure should be
checked periodically (at least monthly) using a tire gauge, see
Inflating your tiresin this chapter. Failure to properly maintain your
tire pressure could increase the risk of tire failure, loss of control,
vehicle rollover and personal injury.
Changing tires with TPMS
Each road tire is equipped with
a tire pressure sensor fastened
to the inside rim of the wheel.
The pressure sensor is covered
by the tire and is not visible
unless the tire is removed. The
pressure sensor is located
opposite (180 degrees) from the
valve stem. Care must be taken
when changing the tire to avoid
damaging the sensor.It is
recommended that you always have
your tires serviced by an authorized
dealer.
The tire pressure should be checked
periodically (at least monthly) using
an accurate tire gauge, refer to
Inflating your tiresin this chapter.
Understanding your Tire Pressure Monitoring System (TPMS)
The Tire Pressure Monitoring System measures pressure in your four
road tires and sends the tire pressure readings to your vehicle. The Low
Tire Warning Lamp will turn ON if the tire pressure is significantly low.
Once the light is illuminated, your tires are under inflated and need to be
inflated to the manufacturer’s recommended tire pressure. Even if the
light turns ON and a short time later turns OFF, your tire pressure still
needs to be checked. Visit www.checkmytires.org for additional
information.

When inflating your tires
When putting air into your tires (such as at a gas station or in your
garage), the Tire Pressure Monitoring System may not respond
immediately to the air added to your tires.
It may take up to two minutes of driving over 20 mph (32 km/h) for the
light to turn OFF after you have filled your tires to the recommended
inflation pressure.
How temperature affects your tire pressure
The Tire Pressure Monitoring System (TPMS) monitors tire pressure in
each pneumatic tire. While driving in a normal manner, a typical
passenger tire inflation pressure may increase approximately 2 to 4 psi
(14 to 28 kPa) from a cold start situation. If the vehicle is stationary
over night with the outside temperature significantly lower than the
daytime temperature, the tire pressure may decrease approximately 3 psi
(20.7 kPa) for a drop of 30° F (16.6°C) in ambient temperature. This
lower pressure value may be detected by the TPMS as being significantly
lower than the recommended inflation pressure and activate the TPMS
warning for low tire pressure. If the low tire pressure warning light is
ON, visually check each tire to verify that no tire is flat. (If one or more
tires are flat, repair as necessary.) Check air pressure in the road tires. If
any tire is under-inflated, carefully drive the vehicle to the nearest
location where air can be added to the tires. Inflate all the tires to the
recommended inflation pressure.
