Mirror Adjustment
Exterior Mirrors
Controls for the outside
power mirrors are located
on the driver door.
1. Move the selector switch left or right to choose the driver side or passenger side mirror.
2. Press one of the four arrows located on the control pad to move the mirror to the desired direction.
3. Return the selector switch to the center position when finished adjusting.
The preferred mirror positions can be stored with the
memory option. See Memory Seat, Mirrors and Steering
Wheel on page 3‑75. The dimming feature automatically adjusts the driver
outside mirror for the glare of the headlamps behind
your vehicle. See
Automatic Dimming Rearview Mirroron page 3‑37for more information.
Manually fold the mirrors inward to prevent damage
when going through an automatic car wash. To fold,
push the mirror toward the vehicle. Push the mirror
outward, to return to its original position.

The vehicle has an automatic dimming inside rearview
mirror. Automatic dimming reduces the glare of lights
from behind the vehicle. The dimming feature comes on
and the indicator light illuminates each time the vehicle
is started.
See Automatic Dimming Rearview Mirror
on page 3‑37for more information.

Lap-Shoulder Belt
All seating positions in your vehicle have a
lap-shoulder belt.
Here is how to wear a lap-shoulder belt properly.1. Adjust the seat, if the seat is adjustable, so you can sit up straight. To see how, see “Seats”in the
Index.
2. Pick up the latch plate and pull the belt across you. Do not let it get twisted.
The lap-shoulder belt may lock if you pull the belt
across you very quickly. If this happens, let the
belt go back slightly to unlock it. Then pull the belt
across you more slowly.
If you ever pull the shoulder portion of a passenger
belt out all the way, you may engage the child
restraint locking feature. If this happens, just let the
belt go back all the way and start again.
3. Push the latch plate into the buckle until it clicks.
Pull up on the latch plate to make sure it is secure.
If the belt is not long enough, see Safety Belt
Extender
on page 2‑34.
Make sure the release button on the buckle is
positioned so you would be able to unbuckle the
safety belt quickly if necessary.
4. If equipped with a shoulder belt height adjuster, move it to the height that is right for you. Improper
shoulder belt height adjustment could reduce the
effectiveness of the safety belt in a crash. See
“Shoulder Belt Height Adjuster” later in this section.

Park Tilt Mirrors
This feature assists the driver by improving rear
obstacle detection and is useful in viewing the curb
when parallel parking.
The passenger and/or driver mirror tilts to a preselected
position when the vehicle is in R (Reverse). This feature
lets the driver view the curb when parallel parking.
If further adjustment is needed after the mirror is tilted,
the mirror switch may be used. The mirror then returns
to this new position when the vehicle is shifted into
R (Reverse).
When the vehicle is shifted out of R (Reverse), and a
five-second delay has occurred, the mirror will return to
its original position. The delay prevents movement of
the mirror if multiple gear transitions R (Reverse) to
D (Drive) to R (Reverse) occur during a parallel parking
maneuver.
If the outside mirror selector switch is in the middle
position, neither outside mirror will move.
Side Blind Zone Alert (SBZA)
If the vehicle has the Side Blind Zone Alert (SBZA)
system, seeSide Blind Zone Alert (SBZA)on
page 3‑44for more information.
Outside Convex Mirror
{WARNING:
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 the right. Check the inside mirror
or glance over your shoulder before changing
lanes.
The passenger side mirror is convex shaped. A convex
mirror's surface is curved so more can be seen from the
driver seat.
Outside Heated Mirrors
For vehicles with this feature:
<(Rear Window Defogger): Press to heat the
mirrors. See “Rear Window Defogger” underDual
Climate Control System
on page 4‑43for more
information.

Outlet Adjustment
Use the lever located in the center of each outlet to
change the direction of the airflow, either side-to-side or
up and down. Use the thumbwheels to open or close
the outlets to adjust the airflow.
Turn the thumbwheel towards the vehicle door to open
the outlets and allow the maximum amount of air to
enter your vehicle. Turn the thumbwheel towards the
center console to close the outlets and minimize the
amount of air entering the vehicle.
Operation Tips
.Clear away any ice, snow or leaves from the air
inlets at the base of the windshield that may block
the flow of air into your vehicle.
.Use of non-GM approved hood deflectors may
adversely affect the performance of the system.
.Keep the path under the front seats clear of
objects to help circulate the air inside of your
vehicle more effectively.
.If the airflow seems low when the fan speed is at
the highest setting, the passenger compartment
air filter may need to be replaced. For more
information, seePassenger Compartment Air
Filter on page 4‑50.
