Periodic Safety Checks You
Should Make Outside The
Vehicle
TiresExamine tires for excessive tread wear
and uneven wear patterns. Check for
stones, nails, glass, or other objects
lodged in the tread or sidewall. Inspect
the tread for cuts and cracks. Inspect
sidewalls for cuts, cracks and bulges.
Check the wheel nuts for tightness.
Check the tires (including spare) for
proper cold inflation pressure.Lights
Have someone observe the operation
of brake lights and exterior lights
while you work the controls. Check
turn signal and high beam indicator
lights on the instrument panel.Door Latches
Check for positive closing, latching,
and locking.
Fluid Leaks
Check area under vehicle after over-
night parking for fuel, engine coolant,
oil, or other fluid leaks. Also, if gaso-
line fumes are detected or if fuel,
power steering fluid (2500/3500), or
brake fluid leaks are suspected, the
cause should be located and corrected
immediately.

25. Tire Pressure Monitoring Tell-
tale LightEach tire, including the
spare (if provided), should
be checked monthly when
cold and inflated to the in-
flation pressure recommended by the
vehicle manufacturer on the vehicle
placard or tire inflation pressure la-
bel. (If your vehicle has tires of a
different size than the size indicated
on the vehicle placard or tire inflation
pressure label, you should determine
the proper tire inflation pressure for
those tires.)
As an added safety feature, your ve-
hicle has been equipped with a Tire
Pressure Monitoring System (TPMS)
that illuminates a low tire pressure
telltale when one or more of your tires
is significantly under-inflated. Ac-
cordingly, when the low tire pressure
telltale illuminates, you should stop
and check your tires as soon as pos-
sible, and inflate them to the proper
pressure. Driving on a significantly
under-inflated tire causes the tire to
overheat and can lead to tire failure. Under-inflation also reduces fuel effi-
ciency and tire tread life, and may
affect the vehicle’s handling and stop-
ping ability.
Please note that the TPMS is not a
substitute for proper tire mainte-
nance, and it is the driver’s responsi-
bility to maintain correct tire pres-
sure, even if under-inflation has not
reached the level to trigger illumina-
tion of the TPMS low tire pressure
telltale.
Your vehicle has also been equipped
with a TPMS malfunction indicator to
indicate when the system is not oper-
ating properly. The TPMS malfunc-
tion indicator is combined with the
low tire pressure telltale. When the
system detects a malfunction, the tell-
tale will flash for approximately one
minute and then remain continuously
illuminated. This sequence will con-
tinue upon subsequent vehicle start-
ups as long as the malfunction exists.
When the malfunction indicator is il-
luminated, the system may not be
able to detect or signal low tire pres-
sure as intended. TPMS malfunctionsmay occur for a variety of reasons,
including the installation of replace-
ment or alternate tires or wheels on
the vehicle that prevent the TPMS
from functioning properly. Always
check the TPMS malfunction telltale
after replacing one or more tires or
wheels on your vehicle, to ensure that
the replacement or alternate tires and
wheels allow the TPMS to continue to
function properly.
CAUTION!
The TPMS has been optimized for
the original equipment tires and
wheels. TPMS pressures and warn-
ing have been established for the
tire size equipped on your vehicle.
Undesirable system operation or
sensor damage may result when us-
ing replacement equipment that is
not of the same size, type, and/or
style. Aftermarket wheels can cause
sensor damage. Do not use tire seal-
ant from a can or balance beads if
your vehicle is equipped with a
TPMS, as damage to the sensors
may result.

TIRE SPINNING
When stuck in mud, sand, snow, or icy
conditions, do not spin your vehicle's
wheels faster than 48 km/h or for
longer than 30 seconds continuously
without stopping.
Refer to “Freeing A Stuck Vehicle” in
“What To Do In Emergencies” for fur-
ther information.WARNING!
Fast spinning tires can be danger-
ous. Forces generated by excessive
wheel speeds may cause tire dam-
age or failure. A tire could explode
and injure someone. Do not spin
your vehicle's wheels faster than
48 km/h or for more than 30 sec-
onds continuously when you are
stuck, and do not let anyone near a
spinning wheel, no matter what the
speed.TREAD WEAR
INDICATORS
Tread wear indicators are in the origi-
nal equipment tires to help you in
determining when your tires should
be replaced.
These indicators are molded into the
bottom of the tread grooves. They will
appear as bands when the tread depth
becomes 2 mm. When the tread is
worn to the tread wear indicators, the
tire should be replaced. LIFE OF TIRE
The service life of a tire is dependent
upon varying factors including but
not limited to:
Driving style
Tire pressure
Distance driven
WARNING!
Tires and spare tire should be re-
placed after six years, regardless of
the remaining tread. Failure to fol-
low this warning can result in sud-
den tire failure. You could lose con-
trol and have a collision resulting in
serious injury or death.
Keep dismounted tires in a cool, dry
place with as little exposure to light as
possible. Protect tires from contact
with oil, grease, and gasoline.
