SAFETY TIPS
Transporting Passengers
NEVER TRANSPORT PASSENGERS IN THE
CARGO AREA.
Exhaust Gas
The best protection against carbon monoxide
entry into the vehicle body is a properly main -
tained engine exhaust system. Whenever a change is noticed in the sound of
the exhaust system, when exhaust fumes can
be detected inside the vehicle, or when the
underside or rear of the vehicle is damaged,
have a competent mechanic inspect the
complete exhaust system and adjacent body
areas for broken, damaged, deteriorated, or
mispositioned parts. Open seams or loose
connections could permit exhaust fumes to
seep into the passenger compartment. In addi
-
tion, inspect the exhaust system each time the
vehicle is raised for lubrication or oil change.
Replace as required.
Safety Checks You Should Make Inside The
Vehicle
Seat Belts
Inspect the seat belt system periodically,
checking for cuts, frays, and loose parts.
Damaged parts must be replaced immediately.
Do not disassemble or modify the system.
Front seat belt assemblies must be replaced
after a collision. Rear seat belt assemblies must
be replaced after a collision if they have been
damaged (i.e., bent retractor, torn webbing,
etc.). If there is any question regarding seat belt
or retractor condition, replace the seat belt.
WARNING!
Do not leave children or animals inside
parked vehicles in hot weather. Interior
heat build-up may cause serious injury or
death.
It is extremely dangerous to ride in a cargo
area, inside or outside of a vehicle. In a
collision, people riding in these areas are
more likely to be seriously injured or killed.
Do not allow people to ride in any area of
your vehicle that is not equipped with seats
and seat belts.
Be sure everyone in your vehicle is in a seat
and using a seat belt properly.
WARNING!
Exhaust gases can injure or kill. They contain
carbon monoxide (CO), which is colorless and
odorless. Breathing it can make you
unconscious and can eventually poison you.
To avoid breathing (CO), follow these safety
tips:
Do not run the engine in a closed garage or
in confined areas any longer than needed
to move your vehicle in or out of the area.
If you are required to drive with the trunk/
liftgate/rear doors open, make sure that all
windows are closed and the climate control
BLOWER switch is set at high speed. DO
NOT use the recirculation mode.
If it is necessary to sit in a parked vehicle
with the engine running, adjust your
heating or cooling controls to force outside
air into the vehicle. Set the blower at high
speed.

392SERVICING AND MAINTENANCE
(Continued)
After a tire rotation is completed, as shown
below, the system can auto learn the loca -
tions of each sensor ID. Auto learning/local -
ization occurs when the vehicle ignition
status is changed from Off to On and speeds
of greater than 5 mph (8 km/h) are obtained and remain over 5 mph (8 km/h) for at about
a 15 minute period. You may need to drive
for 20 minutes to account slower speeds and
stops.
If the tires are rotated incorrectly, the Auto
localization of the TPIS sensors will fail to
locate correctly resulting in incorrect loca -
tions for the pressure values displayed in the
Instrument Cluster.
DEPARTMENT OF TRANSPORTATION
UNIFORM TIRE QUALITY GRADES
The following tire grading categories
were established by the National
Highway Traffic Safety Administration.
The specific grade rating assigned by the
tire's manufacturer in each category is
shown on the sidewall of the tires on
your vehicle.
All passenger vehicle tires must conform
to Federal safety requirements in addi -
tion to these 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 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 varia -
tions in driving habits, service practices,
and differences in road characteristics
and climate.
Traction Grades
The Traction grades, from highest to
lowest, are AA, A, B, and C. These 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.
CAUTION!
4500/5500 Dual Rear Tires may only have
one approved direction of rotation. This is
to accommodate the asymmetrical design
(tread pattern) of the On/Off road tire.
When replacing a flat, the spare tire may
have to be remounted on the rim or
installed at a different location to maintain
the correct placement of the tire on the
wheel relative to the tire/wheel position on
the vehicle. For example, if the spare is
used to replace an outer rear tire it will have
to be remounted on the rim so that the
wheel is dished inward. That way the tread
design of asymmetrical tires will maintain
proper position.
CAUTION! (Continued)

Phone.com .RADIO OPERATION AND MOBILE PHONES
Under certain conditions, the mobile phone
being on in your vehicle can cause erratic or
noisy performance from your radio. This condi -
tion may be lessened or eliminated by relo -
cating the mobile phone antenna. This
condition is not harmful to the radio. If your
radio performance does not satisfactorily
“clear” by the repositioning of the antenna, it is
recommended that the radio volume be turned
down or off during mobile phone operation
when not using Uconnect (if equipped).
