Brake System Warning
Light
The vehicle brake system consists
of two hydraulic circuits. If one
circuit is not working, the remaining
circuit can still work to stop the
vehicle. For normal braking
performance, both circuits need to
be working.
If the warning light comes on, there
is a brake problem. Have the brake
system inspected right away.
MetricEnglish
This light should come on briefly
when the ignition key is turned to
ON/RUN. If it does not come on
then, have it fixed so it will be ready
to warn if there is a problem. This light may also come on due to
low brake fluid. See
Brakes on
page 10‑22 for more information.
When the ignition is on, the brake
system warning light will also come
on when the parking brake is set.
The light will stay on if the parking
brake does not release fully. If it
stays on after the parking brake is
fully released, it means there is a
brake problem.
If the light comes on while driving,
pull off the road and stop carefully.
Make sure the parking brake is
fully released. The pedal may be
harder to push or, the pedal may go
closer to the floor. It may take longer
to stop. If the light is still on, have
the vehicle towed for service. See
Towing the Vehicle on page 10‑82.
{WARNING
The brake system might not be
working properly if the brake
system warning light is on.
Driving with the brake system
warning light on can lead to a
crash. If the light is still on after
the vehicle has been pulled off
the road and carefully stopped,
have the vehicle towed for
service.
The brake message remains on
until any DIC button is pressed. the
brake light remains on until the
problem is fixed. See Brake System
Messages on page 5‑38 for more
information.

Notice: 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.The oil pressure light should come
on briefly as the engine is started.
If it does not come on have the

Blank Display
This display shows no information.Trip/Fuel Menu Items
3(Trip/Fuel): Press this button
to scroll through the following menu
items:
ODOMETER
Press the trip/fuel button until
ODOMETER displays. This display
shows the distance the vehicle has
been driven in either kilometers (km)
or miles (mi). Pressing the trip
odometer reset stem will also
display the odometer.
To switch between English and
metric measurements, see “UNITS”
earlier in this section.
TRIP A and TRIP B
Press the trip/fuel button until
TRIP A or TRIP 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. Pressing the trip odometer
reset stem will also display the trip
odometers. Each trip odometer can be reset to
zero separately by pressing the
set/reset button or the trip odometer
reset stem while the desired trip
odometer is displayed.
The trip odometer has a feature
called retroactive reset. This can be
used to set the trip odometer to
the number of kilometers (miles)
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 retroactive 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 mi) before it is started
again, and then the retroactive reset
feature is activated, the display will

Black plate (29,1)GMC Acadia/Acadia Denali Owner Manual - 2012
Instruments and Controls 5-29
show 8 km (5 mi). As the vehicle
begins moving, the display will then
increase to 8.2 km (5.1 mi), 8.4 km
(5.2 mi), etc.
If the retroactive 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) driven
during the last ignition cycle.
RANGE
Press the trip/fuel button until
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. Fuel range cannot be reset.
AVG (Average) ECONOMY
Press the trip/fuel button until AVG
ECONOMY displays. This display
shows the approximate average
liters per 100 kilometers (L/100 km)
or miles per gallon (mpg).
This number is calculated based
on the number of L/100 km (mpg)
recorded since the last time this
menu item was reset. To reset
AVG ECONOMY, press and hold
the set/reset button.
TIMER
Press the trip/fuel button until
TIMER displays. This display can be
used as a timer.
To start the timer, press the
set/reset button while TIMER is
displayed. The display will show the
amount of time that has passed
since the timer was last reset, not
including time the ignition is off.
Time will continue to be counted as
long as the ignition is on, even if
another display is being shown on
the DIC. The timer will record
up to 99 hours, 59 minutes and
59 seconds (99:59:59) after which
the display will return to zero.
To stop the timer, press the
set/reset button briefly while TIMER
is displayed.
To reset the timer to zero, press and
hold the set/reset button while
TIMER is displayed.

shows the number of liters (L) or
gallons (gal) of fuel used since the
last reset of this menu item. To reset
the fuel used information, press and
hold the set/reset button while FUEL
USED is displayed.
AVG (Average) SPEED
Press the trip/fuel button until
AVG SPEED displays. This display
shows the average speed of the
vehicle in kilometers per hour
(km/h) or miles per hour (mph).
This average is calculated based on
the various vehicle speeds recorded
since the last reset of this value.
To reset the value to zero, press
