TIRES — GENERAL INFORMATION
Tire Pressure
Proper tire inflation pressure is essential to the safe and
satisfactory operation of your vehicle. Four primary
areas are affected by improper tire pressure:
•Safety and Vehicle Stability
• Economy
• Tread Wear
• Ride Comfort
Safety
WARNING!
•Improperly inflated tires are dangerous and can
cause collisions.
• Underinflation increases tire flexing and can re-
sult in overheating and tire failure.
• Overinflation reduces a tire’s ability to cushion
shock. Objects on the road and chuckholes can
cause damage that result in tire failure.

WARNING! (Continued)
•Overinflated or underinflated tires can affect ve-
hicle handling and can fail suddenly, resulting in
loss of vehicle control.
• Unequal tire pressures can cause steering prob-
lems. You could lose control of your vehicle.
• Unequal tire pressures from one side of the ve-
hicle to the other can cause the vehicle to drift to
the right or left.
• Always drive with each tire inflated to the recom-
mended cold tire inflation pressure.
Both under-inflation and over-inflation affect the stabil-
ity of the vehicle and can produce a feeling of sluggish
response or over responsiveness in the steering.
NOTE:
• Unequal tire pressures from side to side may cause
erratic and unpredictable steering response.
• Unequal tire pressure from side to side may cause the
vehicle to drift left or right.
Fuel Economy
Underinflated tires will increase tire rolling resistance
resulting in higher fuel consumption.

STARTING AND OPERATING 219

(20°C) and the measured tire pressure is 27 psi
(186 kPa), a temperature drop to 20°F (-7°C) will
decrease the tire pressure to approximately 23 psi
(159 kPa). This tire pressure is sufficiently low enough
to turn on the Tire Pressure Monitoring Telltale Light.
Driving the vehicle may cause the tire pressure to rise to
approximately 27 psi (186 kPa), but the Tire Pressure
Monitoring Telltale Light will still be on. In this situa-
tion, the Tire Pressure Monitoring Telltale Light will
turn off only after the tires are inflated to the vehicle’s
recommended cold tire pressure value.
CAUTION!
•The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warnings have been established for the tire size
equipped on your vehicle. Undesirable system
operation or sensor damage may result when
using replacement equipment that is not of the
same size, type, and/or style. Aftermarket wheels
can cause sensor damage. Using aftermarket tire
sealants may cause the Tire Pressure Monitoring
System (TPMS) sensor to become inoperable.
(Continued)
CAUTION! (Continued)
After using an aftermarket tire sealant it is recom-
mended that you take your vehicle to an autho-
rized dealership to have your sensor function
checked.
• After inspecting or adjusting the tire pressure,
always reinstall the valve stem cap. This will
prevent moisture and dirt from entering the valve
stem, which could damage the Tire Pressure
Monitoring Sensor.
NOTE:
• The TPMS is not intended to replace normal tire care
and maintenance, or to provide warning of a tire
failure or condition.
• The TPMS should not be used as a tire pressure
gauge while adjusting your tire pressure.
• Driving on a significantly under-inflated tire causes
the tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel efficiency and tire
tread life, and may affect the vehicle’s handling and
stopping ability.

MAINTENANCE SCHEDULE
Your vehicle is equipped with an automatic oil change
indicator system. The oil change indicator system will
remind you that it is time to take your vehicle in for
scheduled maintenance.
Based on engine operation conditions, the oil change
indicator message will illuminate. This means that
service is required for your vehicle. Operating condi-
tions such as frequent short-trips, trailer tow, extremely
hot or cold ambient temperatures, and E85 fuel usage
will influence when the “Change Oil” or “Oil Change
Required” message is displayed. Severe Operating Con-
ditions can cause the change oil message to illuminate
as early as 3,500 miles (5,600 km) since last reset. Have
your vehicle serviced as soon as possible, within the
next 500 miles (805 km).
Your authorized dealer will reset the oil change indica-
tor message after completing the scheduled oil change.
If a scheduled oil change is performed by someone
other than your authorized dealer, the message can be
reset by referring to the steps described under “Instru-
ment Cluster Display” in “Understanding Your Instru-
ment Panel” for further information.NOTE:
Under no circumstances should oil change
intervals exceed 10,000 miles (16,000 km), twelve
months or 350 hours of engine run time, whichever
comes first. The 350 hours of engine run or idle time is
generally only a concern for fleet customers.
Severe Duty All Models
Change Engine Oil at 4,000 miles (6,500 km) if the
vehicle is operated in a dusty and off road environment
or is operated predominantly at idle or only very low
engine RPM’s. This type of vehicle use is considered
Severe Duty.
Once A Month Or Before A Long Trip:
Check engine oil level.
Check windshield washer fluid level.
Check the tire inflation pressures and look for unusual
wear or damage.
Check the fluid levels of the coolant reservoir and brake
master cylinder, and fill as needed.
Check function of all interior and exterior lights.
