The engine will turn off during a
remote vehicle start if:
.The coolant temperature gets
too high.
. The oil pressure gets low.
The RKE transmitter range may be
reduced while the vehicle is running.
Other conditions can affect the
performance of the transmitter.

When the ignition is on, the fuel
gauge indicates about how much
fuel is left in the tank.
There is an arrow near the fuel
gauge pointing to the side of the
vehicle the fuel door is on.
When the indicator nears empty, the
low fuel light comes on. There still is
a little fuel left, but the vehicle
should be refueled soon.
Here are four things that some
owners ask about. None of these
show a problem with the fuel gauge:
.At the service station, the fuel
pump shuts off before the gauge
reads full.
. It takes a little more or less fuel
to fill up than the 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 moves a little while
turning a corner or speeding up. .
The gauge takes a few seconds
to stabilize after the ignition is
turned on, and goes back to
empty when the ignition is
turned off.
Engine Oil Pressure
Gauge
Metric
English
The engine oil pressure gauge
shows the engine oil pressure
in kPa (kilopascals) or psi (pounds
per square inch) when the engine is
running.
Oil pressure can vary with engine
speed, outside temperature, coolant
temperature, and oil viscosity.
On some models, the oil pump will
vary engine oil pressure according
to engine needs. Oil pressure may
change quickly as the engine speed
or load varies. This is normal. If the
oil pressure warning light or Driver

142 Instruments and Controls
indicates oil pressure outside the
normal operating range, check the
vehicle's oil as soon as possible.
SeeEngine Oil 0343.
Caution
Lack of proper engine oil
maintenance can damage the
engine. Driving with the engine oil
low can also damage the engine.
The repairs would not be covered
by the vehicle warranty. Check
the oil level as soon as possible.
Add oil if required, but if the oil
level is within the operating range
and the oil pressure is still low,
have the vehicle serviced. Always
follow the maintenance schedule
for changing engine oil.
If the vehicle has a diesel engine,
see the Duramax diesel
supplement.
Engine Coolant
Temperature Gauge
Metric
English
This gauge measures the
temperature of the vehicle's engine
coolant.
While driving under normal
operating conditions, if the needle
moves into the red warning area,
the engine is too hot. Pull off the
road, stop the vehicle, and turn off
the engine as soon as possible.

Information Displays
Driver Information Center
(DIC) (Base Level)
The DIC displays are shown in the
center of the instrument cluster. The
displays show the status of many
vehicle systems. The trip odometer
reset stem in the instrument cluster
is used to access the DIC menu
items.
DIC Menu Items
Turn the trip odometer reset stem to
scroll through the following menu
items:
.Digital Speedometer
. Trip
. Fuel Range
. Average Fuel Economy
. Tire Pressure
. Remaining Oil Life
. Transmission Fluid Temperature
. Trailer Brake
. Hourmeter .
Unit
Digital Speedometer
The speedometer shows how fast
the vehicle is moving in either
kilometers per hour (km/h) or miles
per hour (mph). The speedometer
cannot be reset.
Trip
Turn the trip odometer reset stem
until TRIP displays. The current
distance traveled, in either
kilometers (km) or miles (mi), since
the last reset for the trip odometer is
shown. The trip odometer can be
reset to zero by pressing and
holding the trip odometer reset stem
while the trip odometer is displayed.
Fuel Range
This display shows the approximate
distance the vehicle can be driven
without refueling. The fuel range
estimate is based on an average of
the vehicle's fuel economy over
recent driving history and the
amount of fuel remaining in the fuel
tank. Fuel range cannot be reset. Average Fuel Economy
The Average Fuel Economy display
shows the approximate average
liters per 100 kilometers (L/100 km)
or miles per gallon (mpg). This
number reflects only the
approximate average fuel economy
that the vehicle has right now, and
will change as driving conditions
change. This number is based on
the number of L/100 km (mpg)
recorded since the last time this
menu item was reset. Reset this
display by pressing the trip
odometer reset stem.
Tire Pressure
Turn the trip odometer reset stem
until a vehicle with the approximate
pressures of all four tires displays.
Tire pressure is displayed in either
kilopascal (kPa) or in pounds per
square inch (psi).

158 Instruments and Controls
Fuel Range :Shows the
approximate distance the vehicle
can be driven without refueling.
LOW will be displayed when the
vehicle is low on fuel. The fuel
range estimate is based on an
average of the vehicle's fuel
economy over recent driving history
and the amount of fuel remaining in
the fuel tank.
Oil Life : Shows an estimate of the
oil's remaining useful life.
If REMAINING OIL LIFE 99% is
displayed, that means 99% of the
current oil life remains.
When the remaining oil life is low,
the CHANGE ENGINE OIL SOON
message will appear on the display.
The oil should be changed as soon
as possible. See Engine Oil0343.
In addition to the engine oil life
system monitoring the oil life,
additional maintenance is
recommended in the Maintenance
Schedule. See Maintenance
Schedule 0443.
The Oil Life display must be reset
after each oil change. It will not
reset itself. Do not reset the Oil Life display at any time other than when
the oil has just been changed.
It cannot be reset accurately until
the next oil change. To reset the
engine oil life system, press and
hold
Vfor several seconds while
the Oil Life display is active. See
Engine Oil Life System 0346.
Tire Pressure : Shows the
approximate pressures of all four
tires. Tire pressure is displayed in
either kilopascal (kPa) or in pounds
per square inch (psi). If the pressure
is low, the value for that tire is
shown in amber. See Tire Pressure
Monitor System 0394 andTire
Pressure Monitor Operation 0395.
Fuel Economy : The center
displays the approximate
instantaneous fuel economy as a
number and bar graph. Displayed
above the bar graph is a running
average of fuel economy for the
most recently traveled selected
distance. Displayed below the bar
graph is the best average fuel
economy that has been achieved for
the selected distance. The selected
distance is displayed at the top of the page as
“last xxx mi/km.” Next
to the odometer, the Active Fuel
Management displays the number of
cylinders the vehicle is running on.
See Active Fuel Management

best average fuel economy. After
reset, the momentary average fuel
economy will display.
The display provides information on
how current driving behavior affects
the running average and how well
recent driving compares to the best
that has been achieved for the
selected distance.
