2008 CHEVROLET EXPRESS warning

For vehicles with a Driver Information Center (DIC), see
DIC Warnings and Messages on page 4-44for all
brake related DIC messages.
StabiliTrak®Indicator Light
For vehicles with the
StabiliTrak®system,
this light comes on or
flashes, according to the
description table for
the StabiliTrak system.
For more information, seeStabiliTrak
®System on
page 5-5.
Three chimes sound if the light turns on and one chime
if the light turns off.
If this light remains on steady, the vehicle needs to be
taken in for service.
Engine Coolant Temperature Gage
This gage shows the engine coolant temperature.
It also provides an indicator of how hard the vehicle is
working. During a majority of the operation, the gage will
read 100°C (210°F) or less. If the vehicle is pulling a load
or going up hills, it is normal for the temperature to
fluctuate and approach the 122°C (250°F) mark. If the
gage reaches the 125°C (260°F) mark, it indicates that
the cooling system is working beyond its capacity.
SeeEngine Overheating on page 6-35.

This can take several days of routine driving. If this
has been done and the vehicle still does not
pass the inspection for lack of OBD II system
readiness, your dealer/retailer can prepare
the vehicle for inspection.
Oil Pressure Gage
The oil pressure gage shows the engine oil pressure in
psi (pounds per square inch) when the engine is
running. Canadian vehicles indicate pressure in
kPa (kilopascals).Oil pressure may vary with engine speed, outside
temperature and oil viscosity, but readings above the
low pressure zone indicate the normal operating range.
A reading in the low pressure zone may be caused
by a dangerously low oil level or other problem causing
low oil pressure. Check your 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. United States

An arrow on the fuel gage indicates the side of the
vehicle the fuel door is on.
The gage first indicates empty before the vehicle is out
of fuel, and the fuel tank should be refueled soon.
Listed are four situations customers might experience
with the fuel gage. None of these indicate a problem with
the fuel gage:
•At the gas station, the fuel pump shuts off before
the gage reads full.
•It takes a little more or less fuel to fill up than the
fuel gage indicated. For example, the gage 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 gage moves a little while turning a corner or
speeding up.
•The gage does not go back to empty when the
ignition is turned off.
If the vehicle has the DURAMAX Diesel engine, see the
DURAMAX Diesel manual for more information.
Driver Information Center (DIC)
Your vehicle has a Driver Information Center (DIC).
All messages will appear in the DIC display located at
the bottom of the instrument panel cluster. The DIC
buttons are located on the instrument panel, next to the
instrument panel cluster.
The DIC comes on when the ignition is on. After a short
delay, the DIC will display the information that was
last displayed before the engine was turned off.
The DIC displays trip, fuel, and vehicle system
information, and warning messages if a system problem
is detected.
If your vehicle has these features, the DIC also displays
the compass direction and the outside air temperature
when viewing the trip and fuel information. The compass
direction appears on the top right corner of the DIC
display. The outside air temperature automatically
appears in the bottom right corner of the DIC display.
If there is a problem with the system that controls
the temperature display, the numbers will be replaced
with dashes. If this occurs, have the vehicle serviced by
your dealer/retailer.
The DIC also allows some features to be customized.
SeeDIC Vehicle Customization on page 4-52for
more information.

Trip Odometers
Press the trip/fuel button until A or B displays. This
display shows the current distance traveled in either
kilometers (km) or miles (mi) since the last reset for each
trip odometer. Both trip odometers can be used at the
same time.
Each trip odometer can be reset to zero separately by
pressing the set/reset button while the desired trip
odometer is displayed.
The trip odometer has a feature called the retro-active
reset. This can be used to set the trip odometer to
the number of miles (kilometers) driven since the ignition
was last turned on. This can be used if the trip
odometer is not reset at the beginning of the trip.
To use the retro-active reset feature, press and hold the
set/reset button for at least four seconds. The trip
odometer will display the number of kilometers (km) or
miles (mi) driven since the ignition was last turned on and
the vehicle was moving. Once the vehicle begins moving,
the trip odometer will accumulate mileage. For example, if
the vehicle was driven 8 km (5 miles) before it is started
again, and then the retro-active reset feature is activated,
the display will show 8 km (5 miles). As the vehicle
begins moving, the display will then increase to 8.1 km
(5.1 miles), 8.2 km (5.2 miles), etc.If the retro-active reset feature is activated after the
vehicle is started, but before it begins moving, the
display will show the number of kilometers (km) or
miles (mi) that were driven during the last ignition cycle.
Fuel Range
Press the trip/fuel button until FUEL RANGE displays.
This display shows the approximate number of
remaining kilometers (km) or miles (mi) the vehicle can
be driven without refueling. The display will show
LOW if the fuel level is low.
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.
This estimate will change if driving conditions change.
For example, if driving in traffic and making frequent
stops, this display may read one number, but if
the vehicle is driven on a freeway, the number may
change even though the same amount of fuel is in the
fuel tank. This is because different driving conditions
produce different fuel economies. Generally, freeway
driving produces better fuel economy than city driving.
If your vehicle is low on fuel, the FUEL LEVEL LOW
message will be displayed. See “FUEL LEVEL LOW”
underDIC Warnings and Messages on page 4-44
for more information.

of the oil’s remaining useful life. If you see 99% OIL LIFE
REMAINING on the display, that means 99% of the
current oil life remains. The engine oil life system
will alert you to change the oil on a schedule consistent
with your driving conditions.
When the remaining oil life is low, the CHANGE
ENGINE OIL SOON message will appear on the display.
See “CHANGE ENGINE OIL SOON” underDIC
Warnings and Messages on page 4-44. You should
