mileage GMC ENVOY DENALI 2008 Owners Manual

Speedometer and Odometer
The speedometer lets you see your speed in both miles
per hour (mph) and kilometers per hour (km/h).
The odometer shows how far your vehicle has been
driven, in either miles (used in the United States)
or kilometers (used in Canada).
The odometer mileage can be checked without the
vehicle running. Press the trip stem located on
the instrument panel cluster.
If your vehicle needs a new odometer installed, the new
one will be set to the correct mileage total of the old
odometer.
Trip Odometer
The trip odometer can tell you how far your vehicle has
been driven since you last set the trip odometer to zero.
The odometer works together with the Driver Information
Center (DIC). You can set a Trip A and Trip B odometer.
See “Trip Information” underDIC Operation and Displays
on page 3-50.
The odometer mileage can be checked without the
vehicle running. Press the trip stem on the instrument
panel cluster.
Tachometer
The tachometer displays
the engine speed in
revolutions per
minute (rpm).
Safety Belt Reminders
Safety Belt Reminder Light
When the engine is started, a chime will come on for
several seconds to remind people to fasten their safety
belts, unless the driver’s safety belt is already buckled.
The safety belt light will
also come on and stay on
for several seconds, then it
will ash for several more.

If you want to do some of your own service work, you
should use the proper service manual. It tells you much
more about how to service your vehicle than this
manual can. To order the proper service manual, see
Service Publications Ordering Information on page 7-16.
Your vehicle has an airbag system. Before attempting to
do your own service work, seeServicing Your
Airbag-Equipped Vehicle on page 1-66.
You should keep a record with all parts receipts and list
the mileage and the date of any service work you
perform. SeeMaintenance Record on page 6-16.Adding Equipment to the Outside of
Your Vehicle
Things you might add to the outside of your vehicle can
affect the airow 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 your vehicle.
Fuel
Use of the recommended fuel is an important part of the
proper maintenance of your 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 this information on the oil container, and
use only those oils that are identied as meeting
GM Standard GM6094M and have the starburst
symbol on the front of the oil container.
Notice:Use only engine oil identied as meeting
GM Standard GM6094M and showing the American
Petroleum Institute Certied For Gasoline Engines
starburst symbol. Failure to use the recommended
oil can result in engine damage not covered by
your warranty.
If you are in an area of extreme cold, where the
temperature falls below−20°F (−29°C), it is
recommended that you use either an SAE 5W-30
synthetic oil or an SAE 0W-30 oil. Both provide easier
cold starting and better protection for the engine at
extremely low temperatures.
Engine Oil Additives
Do not add anything to the oil. The recommended oils
with the starburst symbol that meet GM Standard
GM6094M are all you need for good performance
and engine protection.
Engine Oil Life System
When to Change Engine Oil
Your vehicle has a computer system that lets you know
when to change the engine oil and lter. This is based
on engine revolutions and engine temperature, and not
on mileage. Based on driving conditions, the mileage
at which an oil change will be indicated can vary
considerably. For the oil life system to work properly, you
must reset the system every time the oil is changed.
When the system has calculated that oil life has been
diminished, it will indicate that an oil change is necessary.
A change engine oil light will come on, and, if your vehicle
has a Driver Information Center (DIC), a CHANGE
ENGINE OIL message will come on. See the oil as soon
as possible within the next 600 miles (1 000 km).

dealership management. Normally, concerns can
be quickly resolved at that level. If the matter has

management, it appears your concern cannot be
resolved by the dealership without further help, in the

Courtesy Rental Vehicle
Your dealer may arrange to provide you with a courtesy
rental vehicle or reimburse you for a rental vehicle
that you obtain if your vehicle is kept for an overnight
warranty repair. Rental reimbursement will be limited
and must be supported by original receipts. This
requires that you sign and complete a rental agreement
and meet state/provincial, local, and rental vehicle
provider requirements. Requirements vary and may
include minimum age requirements, insurance coverage,
credit card, etc. You are responsible for fuel usage
charges and may also be responsible for taxes, levies,
usage fees, excessive mileage, or rental usage
beyond the completion of the repair.
It may not be possible to provide a like-vehicle as a
courtesy rental.
Additional Program Information
All program options, such as shuttle service, may not be
available at every dealer. Please contact your dealer
for specic information about availability. All Courtesy
Transportation arrangements will be administered
by appropriate dealer personnel.
General Motors reserves the right to unilaterally modify,
change or discontinue Courtesy Transportation at
any time and to resolve all questions of claim eligibility

herein at its sole discretion.
Collision Damage Repair
If your vehicle is involved in a collision and it is damaged,
have the damage repaired by a qualied technician using
the proper equipment and quality replacement parts.
Poorly performed collision repairs diminish your vehicle’s
resale value, and safety performance can be
compromised in subsequent collisions.
Collision Parts
Genuine GM Collision parts are new parts made with the
same materials and construction methods as the parts
with which your vehicle was originally built. Genuine GM
Collision parts are your best choice to ensure that your
vehicle’s designed appearance, durability, and safety are
preserved. The use of Genuine GM parts can help
maintain your GM New Vehicle Warranty.
Recycled original equipment parts may also be used for
repair. These parts are typically removed from vehicles
that were total losses in prior crashes. In most cases,
the parts being recycled are from undamaged sections
of the vehicle. A recycled original equipment GM part,
may be an acceptable choice to maintain your vehicle’s
originally designed appearance and safety performance,
however, the history of these parts is not known.
Such parts are not covered by your GM New Vehicle
Limited Warranty, and any related failures are not
covered by that warranty.
