CADILLAC STS 2008 1.G Owners Manual

Information Display Menu Items
The following display menu items can be displayed
by pressing the information button.
MPH (km/h)
If your vehicle has this display, it shows the vehicle’s
speed digitally in either miles per hour (mph) or
kilometers per hour (km/h).
MILES RANGE (km RANGE)
This display shows the approximate number of
remaining miles (mi) or kilometers (km) you can drive
without relling the fuel tank. This estimate is based
on the current driving conditions and will change if
the driving conditions change. For example, if you are
driving in traffic making frequent stops, the display
may read one number, but if you enter the freeway,
the number may change even though you still have the
same amount of fuel in the fuel tank. This is because
different driving conditions produce different fuel
economies. Generally, freeway driving produces better
fuel economy than city driving.
Once the range drops below about 40 miles (64 km)
remaining, the display will show LOW RANGE.
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 3-80
for more information.
MPG AVG (L/100 km AVG)
This display shows the approximate average miles per
gallon (mpg) or liters per 100 kilometers (L/100 km).
This number is calculated based on the number of
mpg (L/100 km) recorded since the last time this display
was reset. To reset MPG AVG, press the reset button.
The display will return to zero.
MPG INST (L/100 km INST)
This display shows the current fuel economy. This
number reects only the fuel economy that the vehicle
has right now and will change frequently as driving
conditions change. Unlike average fuel economy,
this display cannot be reset.
GAL FUEL USED (L FUEL USED)
This display shows the number of gallons (gal) or
liters (L) of fuel used since the last reset of this display.
To reset GAL FUEL USED, press the reset button.
The display will return to zero.
AVG MPH (AVG km/h)
This display shows the average speed of the vehicle
in miles per hour (mph) or kilometers per hour (km/h).
This average is calculated based on the various vehicle
speeds recorded since the last reset of this display.
To reset AVG MPH, press the reset button.
The display will return to zero.

If the voltage is low, the display will have LOW after it.
If the voltage is high, the display will have HIGH after it.
Your vehicle’s charging system regulates voltage based
on the state of the battery. The battery voltage may
uctuate when viewing this information on the DIC.
This is normal. SeeCharging System Light on page 3-63
for more information.
If there is a problem with the battery charging system,
the DIC may display a message. SeeDIC Warnings and
Messages on page 3-80andElectric Power Management
on page 3-42for more information.
Tire Pressure
This display shows the pressure for each tire in either
pounds per square inch (psi) or kilopascals (kPa). If the
tire pressure is normal, the value will display. If the tire
pressure is low or high, LOW or HIGH will appear on
the display with the value. SeeInflation - Tire Pressure
on page 5-66andDIC Warnings and Messages on
page 3-80for more information. Press the information
button to scroll through the following displays:
LF TIRE:This display shows the pressure in the driver
side front tire.
RF TIRE:This display shows the pressure in the
passenger side front tire.
LR TIRE:This display shows the pressure in the driver
side rear tire.
RR TIRE:This display shows the pressure in the
passenger side rear tire.
If the tire pressure display shows dashes instead of
a value, there may be a problem with your vehicle.
If this consistently occurs, see your dealer/retailer
for service.
3-78

ENGINE OIL LIFE
If your vehicle has this display, it shows the estimated
oil life remaining. If you see 99% ENGINE OIL LIFE
on the display, that means that 99% of the current oil
life remains.
