2007 GMC ACADIA service indicator

Driver Information Center (DIC)
Your vehicle has a Driver Information Center (DIC).
The DIC displays information about your vehicle.
It also displays warning messages if a system
problem is detected.
All messages will appear in the DIC display
located at the top of 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 also displays a shift lever position
indicator on the bottom line of the display. See
Automatic Transmission Operation on page 129
for more information.The outside air temperature also displays on the
DIC when viewing the trip and fuel information.
The outside air temperature automatically
appears in the top 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.
If your vehicle has DIC buttons, see “DIC Operation
and Displays (With DIC Buttons)” later in this
section andDIC Vehicle Customization (With DIC
Buttons) on page 255for the displays available.
If your vehicle does not have DIC buttons, see
“DIC Operation and Displays (Without DIC
Buttons)” later in this section for the displays
available.

SERVICE TRANSMISSION
This message displays when there is a problem
with the transmission. See your dealer/retailer
for service.
SERVICE VEHICLE SOON
This message displays when a non-emissions
related malfunction occurs. Have the vehicle
serviced by your dealer/retailer as soon as
possible.
SPEED LIMITED TO XXX MPH (KM/H)
This message displays when your vehicle speed
is limited to 80 mph (128 km/h) because the
vehicle detects a problem in the speed variable
assist steering system. Have your vehicle serviced
by your dealer/retailer.
STARTING DISABLED SERVICE
THROTTLE
This message displays when your vehicle’s throttle
system is not functioning properly. Have your
vehicle serviced by your dealer/retailer.
THEFT ATTEMPTED
This message displays if the content theft-deterrent
system has detected a break-in attempt while
you were away from your vehicle. SeeContent
Theft-Deterrent on page 118for more information.
TIGHTEN GAS CAP
This message may display along with the check
engine light on the instrument panel cluster if
the vehicle’s fuel cap is not tightened properly.
SeeMalfunction Indicator Lamp on page 226.
Reinstall the fuel cap fully. SeeFilling the Tank
on page 390. 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
this light and message off.

Gasoline Octane
Use regular unleaded gasoline with a posted
octane rating of 87 or higher. For best performance
or trailer towing, you could choose to use middle
grade 89 octane unleaded gasoline. If the
octane rating is less than 87, you might notice
an audible knocking noise when you drive,
commonly referred to as spark knock. If this
occurs, use a gasoline rated at 87 octane or higher
as soon as possible. If you are using gasoline
rated at 87 octane or higher and you hear heavy
knocking, the engine needs service.
Gasoline Specications
At a minimum, gasoline should meet ASTM
specication D 4814 in the United States or
CAN/CGSB-3.5 or 3.511 in Canada. Some
gasolines contain an octane-enhancing additive
called methylcyclopentadienyl manganese
tricarbonyl (MMT). We recommend against the
use of gasolines containing MMT. SeeAdditives
on page 389for additional information.
California Fuel
If your vehicle is certied to meet California
Emissions Standards, it is designed to operate
on fuels that meet California specications.
See the underhood emission control label.
If this fuel is not available in states adopting
California emissions standards, your vehicle will
operate satisfactorily on fuels meeting federal
specications, but emission control system
performance might be affected. The malfunction
indicator lamp could turn on and your vehicle might
fail a smog-check test. SeeMalfunction Indicator
Lamp on page 226. If this occurs, return to
your authorized dealer/retailer for diagnosis.
If it is determined that the condition is caused
by the type of fuel used, repairs might not
be covered by your warranty.
388

Additives
To provide cleaner air, all gasolines in the
United States are now required to contain additives
that help prevent engine and fuel system
deposits from forming, allowing the emission
control system to work properly. In most cases,
you should not have to add anything to the
fuel. However, some gasolines contain only the
minimum amount of additive required to meet
U.S. Environmental Protection Agency regulations.
To help keep fuel injectors and intake valves
clean, or if your vehicle experiences problems due
to dirty injectors or valves, look for gasoline that
is advertised as TOP TIER Detergent Gasoline.
Also, your dealer/retailer has additives that
will help correct and prevent most deposit-related
problems.
Gasolines containing oxygenates, such as ethers
and ethanol, and reformulated gasolines might
be available in your area. We recommend
that you use these gasolines, if they comply
with the specications described earlier.However, E85 (85% ethanol) and other fuels
containing more than 10% ethanol must not be
used in vehicles that were not designed for
those fuels.
Notice:Your vehicle was not designed for
fuel that contains methanol. Do not use
fuel containing methanol. It can corrode metal
parts in the fuel system and also damage
plastic and rubber parts. That damage would
not be covered under your warranty.
Some gasolines that are not reformulated for low
emissions can contain an octane-enhancing
additive called methylcyclopentadienyl manganese
tricarbonyl (MMT); ask the attendant where you
buy gasoline whether the fuel contains MMT.
We recommend against the use of such gasolines.
Fuels containing MMT can reduce the life of
spark plugs and the performance of the emission
control system could be affected. The malfunction
indicator lamp might turn on. If this occurs,
return to your dealer/retailer for service.
389

Brake Wear
Your vehicle has four-wheel disc brakes.
Disc brake pads have built-in wear indicators that
make a high-pitched warning sound when the
brake pads are worn and new pads are needed.
The sound can come and go or be heard all
the time your vehicle is moving, except when you
are pushing on the brake pedal rmly.
{CAUTION:
The brake wear warning sound means that
soon the brakes will not work well. That
could lead to an accident. When you hear
the brake wear warning sound, have your
vehicle serviced.
Notice:Continuing to drive with worn-out
brake pads could result in costly brake repair.Some driving conditions or climates can cause a
brake squeal when the brakes are rst applied
or lightly applied. This does not mean something
is wrong with the brakes.
Properly torqued wheel nuts are necessary to help
prevent brake pulsation. When tires are rotated,
inspect brake pads for wear and evenly tighten
wheel nuts in the proper sequence to torque
specications inCapacities and Specifications on
page 497.
Brake linings should always be replaced as
complete axle sets.Brake Pedal Travel
See your dealer/retailer if the brake pedal does
not return to normal height, or if there is a
rapid increase in pedal travel. This could be a sign
that brake service might be required.
Brake Adjustment
Every time you apply the brakes, with or without
the vehicle moving, the brakes adjust for wear.
