Performance and Maintenance
StabiliTrak®
The vehicle may have a traction control system that
limits wheel spin and the StabiliTrak system that assists
with directional control of the vehicle in difficult driving
conditions. Both systems turn on automatically every
time the vehicle is started.
.To turn off traction control, press and release5on
the instrument panel.
Filluminates and the
appropriate DIC message displays. See DIC
Warnings and Messages on page 4‑61.
.To turn off both traction control and Electronic
Stability Control, press and hold
5until
Filluminates and the appropriate DIC message
displays. See DIC Warnings and Messageson
page 4‑61.
.Press and release the button again to turn on both
systems.
For more information, see StabiliTrak
®Systemon
page 5‑6.
Tire Pressure Monitor
This vehicle may have a Tire Pressure Monitor
System (TPMS).
The Tire Pressure
Monitor alerts you when
a significant reduction in
pressure occurs in one or
more of the vehicle’s tires
by illuminating the low tire
pressure warning light on
the instrument cluster.
If the warning light comes on, stop as soon as possible
and inflate the tires to the recommended pressure
shown on the tire loading information label located on
the driver side center pillar (B pillar). See Loading the
Vehicle
on page 5‑29. The warning light will remain on
until the tire pressure is corrected.
You may notice during cooler conditions that the low tire
pressure warning light will appear when the vehicle is
first started and then turn off as you drive. This may be
an early indicator that your tire pressures are getting
low and the tires need to be inflated to the proper
pressure.
1-27

The Tire Pressure Monitor can alert you about low tire
pressure, but it does not replace normal monthly tire
maintenance. It is the driver’s responsibility to maintain
correct tire pressures.
See Tire Pressure Monitor System
on page 6‑73and
Tire Pressure Monitor Operation on page 6‑74.
Engine Oil Life System
The engine oil life system calculates engine oil life
based on vehicle use and, on most vehicles, displays
a DIC message when it is necessary to change the
engine oil and filter. The oil life system should be reset
to 100% only following an oil change.
Resetting the Oil Life System
To reset the Engine Oil Life System on most vehicles:
1. Display the OIL LIFE REMAINING on the DIC. If the vehicle does not have DIC buttons, the
vehicle must be in P (Park) to access this display.
2. Press and hold the SET/RESET button on the DIC, or the trip odometer reset stem if the vehicle does
not have DIC buttons, for more than five seconds.
The oil life will change to 100%. On all vehicles, the Engine Oil Life System can be reset
as follows:
1. Turn the ignition to ON/RUN with the engine off
2. Fully press the accelerator pedal slowly three times within five seconds.
3. Display the OIL LIFE REMAINING on the DIC. If the display shows 100%, the system is reset.
See Engine Oil Life System on page 6‑20.
Fuel E85 (85% Ethanol)
Vehicles that have the 5.3L V8 engine (VIN Code 0),
the 5.3L V8 engine (VIN Code 3), the 6.0L V8 engine
(VIN Code J), or the 6.2L V8 engine (VIN Code 2) have
a yellow fuel cap and can use either unleaded gasoline
or ethanol fuel containing up to 85% ethanol (E85).
SeeGasoline Octane
on page 6‑7andFuel E85
(85% Ethanol) on page 6‑9.

Driving for Better Fuel Economy
Driving habits can affect fuel mileage. Here are some
driving tips to get the best fuel economy possible.
.Avoid fast starts and accelerate smoothly.
.Brake gradually and avoid abrupt stops.
.Avoid idling the engine for long periods of time.
.When road and weather conditions are
appropriate, use cruise control, if equipped.
.Always follow posted speed limits or drive more
slowly when conditions require.
.Keep vehicle tires properly inflated.
.Combine several trips into a single trip.
.Replace the vehicle's tires with the same TPC
Spec number molded into the tire's sidewall near
the size.
.Follow recommended scheduled maintenance.

Restraint System Check
Checking the Restraint Systems
Safety Belts
Now and then, check that the safety belt reminder light,
safety belts, buckles, latch plates, retractors, and
anchorages are all working properly.
Look for any other loose or damaged safety belt system
parts that might keep a safety belt system from doing its
job. See your dealer to have it repaired. Torn or frayed
safety belts may not protect you in a crash. They can rip
apart under impact forces. If a belt is torn or frayed, get
a new one right away.
Make sure the safety belt reminder light is working.
SeeSafety Belt Reminders
on page 4‑31for more
information.
Keep safety belts clean and dry. See Care of Safety
Belts
on page 6‑111.
Airbags
The airbag system does not need regularly scheduled
maintenance or replacement. Make sure the airbag
readiness light is working. See Airbag Readiness Light
on page 4‑32for more information.
Notice: If an airbag covering is damaged, opened,
or broken, the airbag may not work properly. Do not
open or break the airbag coverings. If there are any
opened or broken airbag covers, have the airbag
covering and/or airbag module replaced. For the
location of the airbag modules, see What Makes an
Airbag Inflate?
on page 2‑90. See your dealer for
service.

Malfunctions often are indicated by the system before
any problem is apparent. Being aware of the light can
prevent more serious damage to the vehicle. This
system assists the service technician in correctly
diagnosing any malfunction.
Notice:If the vehicle is continually driven with this
light on, after a while, the emission controls might
not work as well, the vehicle's fuel economy might
not be as good, and the engine might not run as
smoothly. This could lead to costly repairs that
might not be covered by the vehicle warranty.
Notice: Modifications made to the engine,
transmission, exhaust, intake, or fuel system of
the vehicle or the replacement of the original tires
with other than those of the same Tire Performance
Criteria (TPC) can affect the vehicle's emission
controls and can cause this light to come on.
Modifications to these systems could lead to costly
repairs not covered by the vehicle warranty. This
could also result in a failure to pass a required
Emission Inspection/Maintenance test. See
Accessories and Modifications on page 6‑4. This light comes on during a malfunction in one of
two ways:
Light Flashing:
A misfire condition has been detected.
A misfire increases vehicle emissions and could
damage the emission control system on the vehicle.
Diagnosis and service might be required.
To prevent more serious damage to the vehicle:
.Reduce vehicle speed.
.Avoid hard accelerations.
.Avoid steep uphill grades.
.If towing a trailer, reduce the amount of cargo
being hauled as soon as it is possible.
If the light continues to flash, when it is safe to do so,
stop the vehicle. Find a safe place to park the vehicle.
Turn the vehicle off, wait at least 10 seconds, and
restart the engine. If the light is still flashing, follow the
previous steps and see your dealer for service as soon
as possible.

Emissions Inspection and Maintenance
Programs
Some state/provincial and local governments may have
programs to inspect the on-vehicle emission control
equipment For the inspection, the emission system test
equipment is connected to the vehicle’s Data Link
Connector (DLC).
The DLC is under the instrument panel to the left of the
steering wheel. See your dealer if assistance is needed.
The vehicle may not pass inspection if:
.the check engine light is on with the engine
running, or if the light does not come on when the
ignition is turned to ON/RUN while the engine
is off.
.the critical emission control systems have not been
completely diagnosed by the system. This can
happen if the battery has recently been replaced or
if the battery has run down. The diagnostic system
evaluates critical emission control systems during
normal driving. This can take several days of
routine driving. If this has been done and the
vehicle still does not pass the inspection, your
dealer can prepare the vehicle for inspection.
Oil Pressure Gauge
United StatesCanada
The oil pressure gauge shows the engine oil pressure
in psi (pounds per square inch) when the engine is
running. Canadian vehicles indicate pressure in kPa
(kilopascals).
4-42

Oil pressure may vary with engine speed, outside
temperature and oil viscosity, but readings above the
low pressure zone indicate the normal operating range.
When the oil pressure reaches the low pressure zone,
the OIL PRESSURE LOW STOP ENGINE message
appears in the Driver Information Center (DIC). SeeDIC
Warnings and Messages
on page 4‑61and Engine Oilon page 6‑17for more information.
A reading in the low pressure zone may be caused by
a dangerously low oil level or some other problem
causing low oil pressure. Check the oil as soon as
possible.
{WARNING:
Do not keep driving if the oil pressure is low. The
engine can become so hot that it catches fire.
Someone could be burned. Check the oil as soon
as possible and have the vehicle serviced.
Notice: Lack of proper engine oil maintenance
can damage the engine. The repairs would not be
covered by the vehicle warranty. Always follow the
maintenance schedule in this manual for changing
engine oil.
If the vehicle is a Two-mode Hybrid, see the Two-mode
Hybrid manual for more information.
