2007 GMC ACADIA Owner's Manual

Shifting Out of Park (P)
Your vehicle has an automatic transmission shift
lock control system. You have to apply your
regular brake rst and then press the shift lever
button before you can shift from PARK (P).
SeeAutomatic Transmission Operation on
page 129.
If you cannot shift out of PARK (P), ease pressure
on the shift lever and push the shift lever all the
way into PARK (P) as you maintain brake
application. Then press the shift lever button and
move the shift lever into the gear you wish.
Parking Over Things That Burn
{CAUTION:
Things that can burn could touch hot
exhaust parts under your vehicle and
ignite. Do not park over papers, leaves,
dry grass, or other things that can burn.
137

Engine Exhaust
{CAUTION:
Engine exhaust can kill. It contains the
gas carbon monoxide (CO), which you
cannot see or smell. It can cause
unconsciousness and death.
You might have exhaust coming in if:
The exhaust system sounds strange
or different.
Your vehicle gets rusty underneath.
Your vehicle was damaged in a
collision.
CAUTION: (Continued)
CAUTION: (Continued)

Your vehicle was damaged when
driving over high points on the road
or over road debris.
Repairs were not done correctly.
Your vehicle or the exhaust system
has been modied improperly.
If you ever suspect exhaust is coming into
your vehicle:
Drive it only with all the windows
down to blow out any CO; and
Have your vehicle xed immediately.
138

Running the Engine While Parked
It is better not to park with the engine running. But if
you ever have to, here are some things to know.
{CAUTION:
Idling the engine with the climate control
system off could allow dangerous exhaust
into your vehicle. See the earlier caution
underEngine Exhaust on page 138.
Also, idling in a closed-in place can let
deadly carbon monoxide (CO) into your
vehicle even if the climate control fan is at
the highest setting. One place this can
happen is a garage. Exhaust — with
CO — can come in easily. NEVER park in
a garage with the engine running.
Another closed-in place can be a blizzard.
SeeWinter Driving on page 356.
{CAUTION:
It can be dangerous to get out of your
vehicle if the shift lever is not fully in
PARK (P) with the parking brake rmly
set. Your vehicle can roll. Do not leave
your vehicle when the engine is running
unless you have to. If you have left the
engine running, the vehicle can move
suddenly. You or others could be injured.
To be sure your vehicle will not move,
even when you are on fairly level ground,
always set the parking brake and move
the shift lever to PARK (P).
Follow the proper steps to be sure your vehicle
will not move. SeeShifting Into Park (P) on
page 135.
If you are pulling a trailer, seeTowing a Trailer on
page 371.

Mirrors
Manual Rearview Mirror with
OnStar
®
When you are sitting in a comfortable driving
position, adjust the mirror so you can see clearly
behind your vehicle. Hold the mirror in the
center to move it up or down and side to side. The
day/night adjustment allows you to adjust the
mirror to avoid glare from the lamps behind you.
Move the lever to the right for nighttime use and to
the left for daytime use.
There may also be three OnStar
®buttons located
at the bottom of the mirror face. SeeOnStar®
System on page 145for more information.
Automatic Dimming Rearview Mirror
with OnStar
®and Compass
Your vehicle may have an automatic-dimming
rearview mirror with a compass.There may be three additional buttons for the
OnStar
®system. See your dealer/retailer for more
information on the system and how to subscribe
to OnStar
®. SeeOnStar®System on page 145for
more information about the services OnStar®
provides.
O(On/Off):This is the on/off button.
Automatic Dimming Mirror Operation
The automatic dimming mirror comes on each time
the ignition is turned to start. To turn the
automatic dimming feature off or back on, press
the on/off button. The indicator light on the mirror is
lit when the automatic dimming feature is on.
Compass Operation
Press the on/off button once to turn the compass
on or off.
There is a compass display in the window in the
upper right corner of the mirror face.
Compass Calibration
Press and hold the on/off button to activate the
compass calibration mode. CAL will be displayed
in the compass window on the mirror.
140

The compass can be calibrated by driving the
vehicle in circles at 5 mph (8 km/h) or less until the
display reads a direction.
If after a few seconds the display does not show a
compass direction, (N for North for example),
there may be a strong magnetic eld interfering
with the compass. Such interference may be
caused by a magnetic antenna mount, note pad
holder, or similar object. If the letter C or CAL
appears in the compass window, the compass may
need to be reset or calibrated.
Compass Variance
Compass variance is the difference between
earth’s magnetic north and true geographic north.
The mirror is set to zone eight upon leaving
the factory. It will be necessary to adjust the
compass to compensate for compass variance if
you live outside zone eight. Under certain
circumstances, such as during a long distance
cross-country trip, it will be necessary to adjust for
compass variance. If not adjusted to account
for compass variance, your compass could give
false readings.To adjust for compass variance:
1. Find your current location and variance zone
number on the following zone map.
2. Press and hold the on/off button until the zone
number is displayed. The number shown is
the current zone number.
141

3. Scroll through the zone numbers that appear
in the window on the mirror by pressing the
on/off button. Once you nd your zone
number, release the button. After about
four seconds, the mirror will return to the
compass display, and the new zone number
will be set. If C or CAL appears in the
compass window, the compass may need
calibration. See “Compass Calibration” listed
previously.
Outside Power Mirrors
If your vehicle is
equipped with outside
power mirrors, the
controls are located on
the driver’s door
armrest.Press (A) to select the driver’s side mirror or (B) to
select the passenger’s side mirror. Press either (A)
or (B) again to deselect the mirror.
To adjust each mirror, press one of the four
arrows located on the control pad to move the
mirror in the direction you want it to go. Adjust
each outside mirror so that you can see a little of
your vehicle, and the area behind your vehicle.
SeeMemory Seat and Mirrors on page 13for more
information.
The mirrors can be manually folded inward to
prevent damage when going through an automatic
car wash. To fold, push the mirror toward the
vehicle. To return the mirror to its original position,
push outward. Be sure to return both mirrors to
their original unfolded position before driving.
The use of hood-mounted air deectors and
add-on convex mirror attachments may adversely
affect mirror performance.

The mirrors are accidentally obstructed while
folding.
They are accidentally manually
folded/unfolded.
The mirrors will not stay in the unfolded

Automatic Dimming
The driver’s outside mirror will adjust for the glare
of the headlamps behind you. SeeAutomatic
Dimming Rearview Mirror with OnStar
®and
Compass on page 140.
Curb View Assist
If your vehicle has the memory package, the
outside mirrors are able to perform the curb view
assist mirror function. This feature may be
useful in allowing the driver to view the curb when
parallel parking. This feature will cause the
passenger’s and/or driver’s mirror to tilt to a
preselected position when the vehicle is in
REVERSE (R).
The passenger’s and/or driver’s mirror will return
to its original position when the vehicle is
shifted out of REVERSE (R), or the ignition is
turned off or to LOCK.
This feature can be turned on or off through the
Driver Information Center (DIC). SeeDriver
Information Center (DIC) on page 232andMemory
Seat and Mirrors on page 13for more information.
Turn Signal Indicator
Your vehicle may have a turn signal indicator on
the mirror. An arrow on the mirror will ash in
the direction of the turn or lane change.
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 lane, you could hit a vehicle on
your right. Check your inside mirror or
glance over your shoulder before
changing lanes.
The passenger’s side mirror may have convex
glass. A convex mirror’s surface is curved so more
can be seen from the driver’s seat.
