light CHEVROLET SUBURBAN 2010 10.G Manual Online

When the Light is On Steady
This indicates that one or more of the tires is
significantly underinflated.
A tire pressure message in the Driver Information
Center (DIC), can accompany the light. SeeDriver
Information Center (DIC)
on page 4‑47for more
information. Stop and check the tires as soon as it is
safe to do so. If underinflated, inflate to the proper
pressure. See Inflation - Tire Pressure
on page 6‑72for more information.
When the Light Flashes First and Then is
On Steady
This indicates that there may be a problem with the
Tire Pressure Monitor System. The light flashes for
about a minute and stays on steady for the remainder
of the ignition cycle. This sequence repeats with every
ignition cycle. See Tire Pressure Monitor Operation
on
page 6‑74for more information.
Malfunction Indicator Lamp
Check Engine Light
A computer system called OBD II (On-Board
Diagnostics-Second Generation) monitors operation
of the fuel, ignition, and emission control systems.
It ensures that emissions are at acceptable levels for
the life of the vehicle, helping to produce a cleaner
environment.
This light should come on
when the ignition is on,
but the engine is not
running, as a check to
show it is working. If it
does not, have the vehicle
serviced by your dealer.
If the check engine light comes on and stays on, while
the engine is running, this indicates that there is an
OBD II problem and service is required.
4-39

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.
4-40

Light On Steady:An emission control system
malfunction has been detected on the vehicle.
Diagnosis and service might be required.
An emission system malfunction might be corrected by
doing the following:
.Make sure the fuel cap is fully installed. See Filling
the Tankon page 6‑11. The diagnostic system
can determine if the fuel cap has been left off or
improperly installed. A loose or missing fuel cap
allows fuel to evaporate into the atmosphere. A few
driving trips with the cap properly installed should
turn the light off.
.If the vehicle has been driven through a deep
puddle of water, the vehicle's electrical system
might be wet. The condition is usually corrected
when the electrical system dries out. A few driving
trips should turn the light off.
.Make sure to fuel the vehicle with quality fuel.
Poor fuel quality causes the engine not to run as
efficiently as designed and can cause: stalling
after start-up, stalling when the vehicle is changed
into gear, misfiring, hesitation on acceleration,
or stumbling on acceleration. These conditions
might go away once the engine is warmed up.
If one or more of these conditions occurs, change
the fuel brand used. It will require at least one full
tank of the proper fuel to turn the light off.
See Gasoline Octane on page 6‑7.
If none of the above have made the light turn off, your
dealer can check the vehicle. The dealer has the
proper test equipment and diagnostic tools to fix any
mechanical or electrical problems that might have
developed.

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.

Fuel Gauge
United StatesCanada
The fuel gauge, when the ignition is on, shows how
much fuel the vehicle has left in the tank.
An arrow on the fuel gauge indicates the side of the
vehicle the fuel door is on.
4-45

The gauge first indicates empty before the vehicle is out
of fuel, and the vehicle's fuel tank should be filled soon.
When the fuel tank is low, the FUEL LEVEL LOW
message appears in the Driver Information Center
(DIC). SeeDIC Warnings and Messages
on page 4‑61for more information.
Here are some situations owners may experience with
the fuel gauge. None of these indicate a problem with
the fuel gauge.
.At the gas station, the fuel pump shuts off before
the gauge reads full.
.It takes a little more or less fuel to fill up than the
fuel gauge indicated. For example, the gauge may
have indicated the tank was half full, but it actually
took a little more or less than half the tank's
capacity to fill the tank.
.The gauge goes back to empty when the ignition is
turned off.
For vehicles with a Two-mode Hybrid, see the
Two-mode Hybrid manual for more information.
Low Fuel Warning Light
This light, under the fuel
gauge, comes on briefly
while the engine is being
started.
This light and a chime comes on when the fuel tank is
low on fuel. The Driver Information Center also displays
a “FUEL LEVEL LOW” message. SeeDIC Warnings
and Messages
on page 4‑61for more information.

4. Press the trip/fuel button until the vehicle heading,for example, N for North, is displayed in the DIC.
Or, if the vehicle does not have DIC buttons,
press and hold the trip odometer reset stem for
two seconds to select the next available variance
zone. Repeat this step until the appropriate
variance zone is displayed.
5. If calibration is necessary, calibrate the compass. See “Compass Calibration Procedure” following.
Compass Calibration
The compass can be manually calibrated. Only calibrate
the compass in a magnetically clean and safe location,
such as an open parking lot, where driving the vehicle
in circles is not a danger. It is suggested to calibrate
away from tall buildings, utility wires, manhole covers,
or other industrial structures, if possible.
If CAL should ever appear in the DIC display, the
compass should be calibrated.
If the DIC display does not show a heading, for
example, N for North, or the heading does not change
after making turns, there may be a strong magnetic field
interfering with the compass. Such interference may be
caused by a magnetic CB or cell phone antenna mount,
a magnetic emergency light, magnetic note pad holder,
or any other magnetic item. Turn off the vehicle, move
the magnetic item, then turn on the vehicle and calibrate
the compass. To calibrate the compass, use the following procedure:
Compass Calibration Procedure
1. Before calibrating the compass, make sure the
compass zone is set to the variance zone in which
the vehicle is located. See “Compass Variance
(Zone) Procedure” earlier in this section.
Do not operate any switches such as window,
sunroof, climate controls, seats, etc. during the
calibration procedure.
2. Press the vehicle information button until PRESS
VTO CALIBRATE COMPASS displays.
Or, if the vehicle does not have DIC buttons, press
the trip odometer reset stem until CALIBRATE
COMPASS displays.
3. Press the set/reset button to start the compass calibration. Or, if the vehicle does not have DIC
buttons, press and hold the trip odometer reset
stem for two seconds to start the compass
calibration.
4. The DIC will display CALIBRATING: DRIVE IN CIRCLES. Drive the vehicle in tight circles at less
than 5 mph (8 km/h) to complete the calibration.
The DIC will display CALIBRATION COMPLETE
for a few seconds when the calibration is complete.
The DIC display will then return to the
previous menu.
