2009 GMC ENVOY DENALI steering

2. If the engine does not start after 5-10 seconds,
especially in very cold weather (below 0°F or−18°C),
it could be ooded with too much gasoline. Try
pushing the accelerator pedal all the way to the oor
and holding it there as you hold the key in START for
up to a maximum of 15 seconds. Wait at least
15 seconds between each try, to allow the cranking
motor to cool down. When the engine starts, let go of
the key and accelerator. If the vehicle starts briey
but then stops again, repeat these steps. This clears
the extra gasoline from the engine. Do not race the
engine immediately after starting it. Operate the
engine and transmission gently until the oil warms up
and lubricates all moving parts.
Notice:The engine is designed to work with the
electronics in the vehicle. If you add electrical parts
or accessories, you could change the way the
engine operates. Before adding electrical equipment,
check with your dealer/retailer. If you do not, the
engine might not perform properly. Any resulting
damage would not be covered by the vehicle
warranty.Adjustable Throttle and Brake Pedal
If the vehicle has this feature, you can change the
position of the throttle and brake pedals.
The vehicle must be in P (Park) for this feature to
operate.
The switch used to adjust
the pedals is located on
the steering column.
Press the switch forward or backward to move the
pedals closer or farther away from you.

Automatic Transfer Case

is located to the right of the steering wheel on the
instrument panel.
Use this knob to shift into
and out of four-wheel
drive.
2
m(Two-Wheel High):This setting is for driving in
most street and highway situations. The front axle is not
engaged in two-wheel drive. This provides the best fuel
economy.AUTO (Automatic Four-Wheel Drive):This setting is
ideal for use when road conditions are variable. When
driving the vehicle in automatic four-wheel drive, the front
axle is engaged, but the vehicle’s power is sent to the
rear wheels. When the vehicle senses a loss of traction,
the system will automatically engage four-wheel drive.
Driving in this mode results in slightly lower fuel economy
than Two-Wheel High.
4
m(Four-Wheel High):This setting should be used
when you need extra traction, such as on snowy or icy
roads or in most off-road situations. This setting also
engages the front axle to help drive the vehicle.

OnStar Virtual Advisor
OnStar Virtual Advisor is a feature of OnStar Hands-Free
Calling that uses minutes to access location-based
weather, local traffic reports, and stock quotes. Press the
phone button and give a few simple voice commands to
browse through the various topics. See the OnStar
Owner’s Guide for more information. This feature is only
available in the continental U.S.
OnStar Steering Wheel Controls
This vehicle may have a Talk/Mute button that can be
used to interact with OnStar Hands-Free Calling.
SeeAudio Steering Wheel Controls on page 3-110for
more information.
On some vehicles, the mute button can be used to dial
numbers into voice mail systems, or to dial phone
extensions. See the OnStar Owner’s Guide for more
information.
How OnStar Service Works
The OnStar system can record and transmit vehicle
information. This information is automatically sent to an
OnStar Call Center when the OnStar button is
pressed, the emergency button is pressed, or if the
airbags or AACN system deploy. This information
usually includes the vehicle’s GPS location and, in the
event of a crash, additional information regarding
the crash that the vehicle was involved in (e.g. the
direction from which the vehicle was hit). When
the Virtual Advisor feature of OnStar Hands-Free Calling
is used, the vehicle also sends OnStar the vehicle’s
GPS location so they can provide services where it is
located.
OnStar service cannot work unless the vehicle is in a
place where OnStar has an agreement with a wireless
service provider for service in that area. OnStar
service also cannot work unless the vehicle is in a place
where the wireless service provider OnStar has hired
for that area has coverage, network capacity and
reception when the service is needed, and technology
that is compatible with the OnStar service. Not all
services are available everywhere, particularly in remote
or enclosed areas, or at all times.
