Speedometer and Odometer
The speedometer shows the vehicle's speed in both
miles per hour (mph) and kilometers per hour (km/h).
The odometer mileage can be checked without the
vehicle running. Simply press the trip stem on the
instrument panel cluster.
If the vehicle ever needs a new odometer installed,
the new one is set to the correct mileage total of the
old odometer.
Trip Odometer
The trip odometer can show how far the vehicle has
been driven since the trip odometer was last set to zero.
Press the reset button, located on the instrument panel
cluster next to the trip odometer display, to toggle
between the trip odometer and the regular odometer.
Holding the reset button for approximately one second
while the trip odometer is displayed resets it.
To display the odometer reading with the ignition off,

revolutions per minute (rpm).
Safety Belt Reminders
Driver Safety Belt Reminder Light
When the engine is started, a chime sounds for several
seconds to remind a driver to fasten the safety belt,
unless the driver safety belt is already buckled.
The safety belt light
flashes for several
seconds, then comes on
solid for several more.
This chime and light sequence are repeated if the driver
remains unbuckled and the vehicle is in motion. If the
driver safety belt is already buckled, neither the chime
nor the light comes on.

Odometer
Press the trip/fuel button until ODOMETER displays.
This display shows the distance the vehicle has been
driven in either miles (mi) or kilometers (km). Pressing
the trip odometer reset stem will also display the
odometer.
To switch between English and metric measurements,
see “Units” later in this section.
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.

This vehicle has an airbag system. Before attempting
to do your own service work, seeServicing Your
Airbag-Equipped Vehicle on page 2‑91.
Keep a record with all parts receipts and list the
mileage and the date of any service work performed.
See Maintenance Record on page 7‑15.
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
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.
This vehicle can use either unleaded gasoline or
ethanol fuel containing up to 85% ethanol (E85).
See
Gasoline Octane
on page 6‑6andFuel E85
(85% Ethanol) on page 6‑7.

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 4‑56. 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.
