2005 GMC ENVOY XUV lane assist

After adjusting the position of the mirrors, turn the
knob to the center position so that the mirrors
cannot move.
If the travel position in any direction of the mirror is
reached, it will enter a ratcheting mode. This action is
harmless. It is a warning that the mirror can go no
further. To stop this action, back the mirror up by moving
the knob in the opposite direction.
Outside Curb View Assist Mirror
If the vehicle has this feature, the passenger’s outside
mirror will adjust to a preset tilt position while the vehicle
is in REVERSE (R) gear. Curb view assist may be
useful when you are parallel parking. The mirror
will return to normal position when the vehicle is shifted
out of REVERSE (R) gear. Automatic mirror movement
in either direction will follow a short delay.
You may be able to turn this feature on or off through
the Driver Information Center (DIC). SeeDIC Vehicle
Customization on page 3-57.
Outside Convex Mirror
{CAUTION:
A convex mirror can make things (like other
vehicles) look farther away than they really are.
If you cut too sharply into the right or left lane,
you could hit a vehicle. Check your inside
mirror or glance over your shoulder before
changing lanes.
The passenger’s outside mirror is convex. A convex
mirror’s surface is curved so more can be seen from the
driver’s seat.
Outside Heated Mirrors
If the vehicle has this feature, when the rear window
defogger is turned on, the outside driver’s and
passenger’s rearview mirrors also heat to help clear
them of ice, snow, and condensation. SeeDual Climate
Control System on page 3-20orDual Automatic
Climate Control System on page 3-23for more
information.

If you drive regularly in steep country, or if you are
planning to visit there, here are some tips that can make
your trips safer and more enjoyable. SeeOff-Road
Driving with Your Four-Wheel-Drive Vehicle on
page 4-16for information about driving off-road.
Keep your vehicle in good shape. Check all uid
levels and also the brakes, tires, cooling system,
and transmission. These parts can work hard
on mountain roads.
Know how to go down hills. The most important
thing to know is this: let your engine do some of
the slowing down. Shift to a lower gear when you go
down a steep or long hill.
{CAUTION:
If you do not shift down, your brakes could
get so hot that they would not work well.
You would then have poor braking or even
none going down a hill. You could crash.
Shift down to let your engine assist your
brakes on a steep downhill slope.
{CAUTION:
Coasting downhill in NEUTRAL (N) or with the
ignition off is dangerous. Your brakes will have
to do all the work of slowing down. They could
get so hot that they would not work well.
You would then have poor braking or even
none going down a hill. You could crash.
Always have your engine running and your
vehicle in gear when you go downhill.
Know how to go uphill. You may want to shift down to
a lower gear. The lower gears help cool your engine
and transmission, and you can climb the hill better.
Stay in your own lane when driving on two-lane
roads in hills or mountains. Do not swing wide or cut
across the center of the road. Drive at speeds that let
you stay in your own lane.
As you go over the top of a hill, be alert. There could
be something in your lane, like a stalled car or an
accident.
You may see highway signs on mountains that warn
of special problems. Examples are long grades,
passing or no-passing zones, a falling rocks area,
or winding roads. Be alert to these and take
appropriate action.

Vehicle Data Collection and
Event Data Recorders
Your vehicle, like other modern motor vehicles, has a
number of sophisticated computer systems that
monitor and control several aspects of the vehicle’s
performance. Your vehicle uses on-board vehicle
computers to monitor emission control components to
optimize fuel economy, to monitor conditions for airbag
deployment and, if so equipped, to provide anti-lock
braking and to help the driver control the vehicle in
difficult driving situations. Some information may be
stored during regular operations to facilitate repair of
detected malfunctions; other information is stored only in
a crash event by computer systems, such as those
commonly called event data recorders (EDR).
In a crash event, computer systems, such as the Airbag
Sensing and Diagnostic Module (SDM) in your vehicle
may record information about the condition of the vehicle
and how it was operated, such as data related to engine
speed, brake application, throttle position, vehicle speed,
safety belt usage, airbag readiness, airbag performance,
and the severity of a collision. This information has been
used to improve vehicle crash performance and may be
used to improve crash performance of future vehicles
and driving safety. Unlike the data recorders on many
airplanes, these on-board systems do not record sounds,
such as conversation of vehicle occupants.
