Driving for Better Fuel Economy
Driving habits can affect fuel mileage. Here are some
driving tips to get the best fuel economy possible.
.Avoid fast starts and accelerate smoothly.
.Brake gradually and avoid abrupt stops.
.Avoid idling the engine for long periods of time.
.When road and weather conditions are
appropriate, use cruise control, if equipped.
.Always follow posted speed limits or drive more
slowly when conditions require.
.Keep vehicle tires properly inflated.
.Combine several trips into a single trip.
.Replace the vehicle's tires with the same TPC
Spec number molded into the tire's sidewall near
the size.
.Follow recommended scheduled maintenance.

Trip Odometer
Press the trip/fuel button until TRIP displays. This
display shows the current distance traveled in either
miles (mi) or kilometers (km) since the last reset for the
trip odometer. Pressing the trip odometer reset stem will
also display the trip odometer.
The trip odometer can be reset to zero by pressing the
set/reset button while the trip odometer is displayed.
You can also reset the trip odometer while it is
displayed by pressing and holding the trip odometer
reset stem.
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 miles (mi) or
kilometers (km) 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
5 miles (8 km) before it is started again, and then the
retro-active reset feature is activated, the display will
show 5 miles (8 km). As the vehicle begins moving,
the display will then increase to 5.1 miles (8.2 km),
5.2 miles (8.4 km), etc.
Fuel Range
Press the trip/fuel button until FUEL RANGE displays.
This display shows the approximate number of
remaining miles (mi) or kilometers (km) 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.
Average Economy
Press the trip/fuel button until AVG ECONOMY
displays. 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 menu item was reset. To reset AVG ECONOMY,
press and hold the set/reset button.

Keep a record with all parts receipts and list the
mileage and the date of any service work performed.
SeeMaintenance Record on page 7‑17.
Adding Equipment to the Outside of
the Vehicle
Things added to the outside of the vehicle can affect
the airflow around it. This can cause wind noise and
can affect fuel economy and windshield washer
performance. Check with your dealer/retailer before
adding equipment to the outside of the vehicle.
Fuel
For diesel engine vehicles, see “Diesel Fuel
Requirements and Fuel System” in the DURAMAX®
Diesel manual.
For vehicles with gasoline engines, please read this.
Gasoline
Use of the recommended fuel is an important part of
the proper maintenance of this vehicle. To help keep
the engine clean and maintain optimum vehicle
performance, we recommend the use of gasoline
advertised as TOP TIER Detergent Gasoline. Look for the TOP TIER label on the fuel pump to ensure
gasoline meets enhanced detergency standards
developed by auto companies. A list of marketers
providing TOP TIER Detergent Gasoline can be found
at www.toptiergas.com.

Engine Oil Additives / Engine Oil
Flushes
Do not add anything to the oil. The recommended oils
with the starburst symbol that meet GM Standard
GM6094M are all that is needed for good performance
and engine protection.
Engine oil system flushes are not recommended and
could cause engine damage not covered by the
vehicle warranty.
Engine Oil Life System
When to Change Engine Oil
This vehicle has a computer system that indicates when
to change the engine oil and filter. This is based on
engine revolutions and engine temperature, and not on
mileage. Based on driving conditions, the mileage at
which an oil change is indicated can vary considerably.
For the oil life system to work properly, the system must
be reset every time the oil is changed.
On some vehicles, when the system has calculated that
oil life has been diminished, a CHANGE ENGINE OIL
SOON message comes on to indicate that an oil
change is necessary. SeeDIC Warnings and Messages
on page 4‑65. Change the oil as soon as possible
within the next 1 000 km (600 miles). It is possible that, if driving under the best conditions, the oil life system
might not indicate that an oil change is necessary for
over a year. However, the engine oil and filter must be
changed at least once a year and at this time the
system must be reset. For vehicles without the
CHANGE ENGINE OIL SOON message, An oil change
is needed when the OIL LIFE REMAINING percentage
is near 0%. Your dealer/retailer has trained service
people who will perform this work using genuine parts
and reset the system. It is also important to check the
oil regularly and keep it at the proper level.
If the system is ever reset accidentally, the oil must be
changed at 5 000 km (3,000 miles) since the last oil
change. Remember to reset the oil life system
whenever the oil is changed.
How to Reset the Engine Oil Life
System
The Engine Oil Life System calculates when to
change the engine oil and filter based on vehicle use.
Whenever the oil is changed, reset the system so it can
calculate when the next oil change is required. If a
situation occurs where the oil is changed prior to a
CHANGE ENGINE OIL SOON message coming on,
reset the system.

Customer Assistance and
Information
Customer Satisfaction Procedure
Your satisfaction and goodwill are important to your
dealer and to GMC. Normally, any concerns with the
sales transaction or the operation of the vehicle will be
resolved by the dealer's sales or service departments.
Sometimes, however, despite the best intentions of all
concerned, misunderstandings can occur. If your
concern has not been resolved to your satisfaction,
the following steps should be taken:
STEP ONE :Discuss your concern with a member of
dealership management. Normally, concerns can be
quickly resolved at that level. If the matter has already
been reviewed with the sales, service or parts manager,
contact the owner of the dealership or the general
manager. STEP TWO :
If after contacting a member of dealership
management, it appears your concern cannot be
resolved by the dealership without further help, in the
U.S., call the GMC Consumer Relations Manager at
1-800-GMC-8782 (1-800-462-8782, Customer
Assistance prompt). In Canada, call General Motors of
Canada Customer Communication at 1-800-263-3777
(English) or 1-800-263-7854 (French).
We encourage you to call the toll-free number in order
to give your inquiry prompt attention. Have the following
information available to give the Customer Assistance
Representative:
.Vehicle Identification Number (VIN). This is
available from the vehicle registration or title, or the
plate at the top left of the instrument panel and
visible through the windshield.
.Dealership name and location.
.Vehicle delivery date and present mileage.
When contacting GMC, remember that your concern will
likely be resolved at a dealer's facility. That is why we
suggest following Step One first.
