Battery Run-Down Protection
This feature shuts off the dome, courtesy, vanity,
reading, glove box and underhood lamps if they are left
on for more than 20 minutes when the ignition is off.
This will keep your battery from running down.
If the battery run
-down protection shuts off the interior
lamps, it may be necessary to do one of the following to
return to normal operation:

Shut off all lamps and close all doors, or

turn the ignition key to RUN.
This feature will also turn off the parking lamps and
headlamps under most circumstances, if they are left on.
If you would like to turn them back on, turn the exterior
lamps knob on.
Mirrors
Adjust all the mirrors so you can see clearly when you
are sitting in a comfortable driving position.

Automatic Dimming Feature
When turned on, an electrochromic mirror automatically
dims to the proper level to minimize glare from any
headlamps behind you after dark.
The automatic dimming feature is turned on and off by
pressing the far left button, located on the lower part of
the mirror face, for up to three seconds. A light on the
mirror will be lit when the feature is turned on. It will go
out when the feature is turned off.
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. The compass displays a
maximum of two characters. For example, ªNEº is
displayed for north
-east.Compass Calibration
Press and hold the on/off button down for nine seconds
to activate the compass calibration mode. ªCALº will be
displayed in the compass window on the mirror.
The mirror can be calibrated in one of two ways:

Drive the vehicle in circles at 5 mph (8 km/h) or less
until the display shows ªCAL,º or

drive the vehicle on your everyday routine.
(This method may take longer to calibrate).
Compass Variance
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. Compass variance is the
difference between earth's magnetic north and true
geographic north. If not adjusted to account for compass
variance, your compass could give false readings.
To adjust for compass variance, do the following:
1. Find your current location and variance zone number
on the map.

Convex Outside Mirror
A convex mirror's surface is curved so you can see more
from the driver's seat.
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.
Heated Outside Rearview Mirrors
When you operate the rear window defogger, a defogger
also warms the heated driver's and passenger's outside
rearview mirrors to help clear them of ice, snow and
condensation. See ªRear Window Defoggerº in the
Index for more information.
Electrochromic Rearview Outside Mirror
with Curb View Assist (If Equipped)
If your vehicle has this feature, the driver's outside
mirror will adjust for the glare of the headlamps behind
you. See ªElectrochromic Day/Night Rearview Mirror
with Compass and OnStar

º earlier in this section.
If your vehicle is equipped with memory mirrors, it will
also be capable of performing the curb view assist
mirror function. 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). This feature may
be useful in allowing you to view the curb when you are
parallel parking.
When the vehicle is shifted out of REVERSE (R) and a
short delay has occurred, the passenger's and/or driver's
mirror will return to its original position.
To change the preselected tilt position, adjust the mirrors
to the desired position while the vehicle is in
REVERSE (R). When the vehicle is shifted out of
REVERSE (R), this new position is saved in memory as
the tilt position.
This feature can be enabled/disabled through the Driver
Information Center. See ªPersonalization Featuresº in
the Index for more information.

3-6
To find your comfort setting, start with a 74
F (23
C)
temperature setting and allow about 20 minutes for the
system to regulate. Turn the driver's or passenger's side
temperature knob clockwise or counterclockwise to
adjust the temperature setting as necessary. If you
choose the temperature setting of 60
F (15
C), the
system will remain at the maximum cooling setting
and fan speed. If you choose the temperature setting of
90
F (32
C), the system will remain at the maximum
heat setting and fan speed. Choosing either maximum
setting will not cause the system to heat or cool any
faster.
Be careful not to cover the sensor located on the top of
the instrument panel near the windshield. This sensor
regulates air temperature based on sun load, and also
turns on your headlamps.
The EXT (exterior) temperature sensor is located in the
front of the vehicle behind the grille. The displayed
temperature is most accurate after the vehicle has been
moving for a few minutes. If the vehicle is stopped and
then restarted within 2 1/2 hours, the sensor will be hot
from the engine heat. In this case, the temperature first
displayed will continue to be the temperature that was
displayed before the vehicle was turned off. The display
will update after the vehicle has been moving for a few
minutes and the sensor has a chance to cool down to the
actual temperature.To avoid blowing cold air in cold weather, the system
will delay turning on the fan until warm air is available.
The length of delay depends on the engine coolant
temperature. Pushing the fan switch will override this
delay and change the fan to a selected speed.
Manual Operation
You may manually adjust the air delivery mode or fan
speed. Use the mode button to cycle through the
following four air delivery modes:
(Panel): This setting will deliver air to the
instrument panel outlets.
(Bi-Level): This setting will deliver warmer air to
the floor and cooler air to the instrument panel outlets.
(Floor): This setting will deliver air to the
floor outlets.
(Defog): This setting will deliver air to the floor
and windshield outlets.
OFF: Press this button to turn the system off. Some
fresh air will continue to flow through the vehicle from
the floor outlets. The system will try to maintain the
previously chosen temperature setting.

4-21 Driving Uphill
Once you decide you can safely drive up the hill, you
need to take some special steps.

Use a low gear and get a firm grip on the
steering wheel.

Get a smooth start up the hill and try to maintain
your speed. Don't use more power than you need,
because you don't want your wheels to start spinning
or sliding.

Try to drive straight up the hill if at all possible.
If the path twists and turns, you might want to find
another route.
CAUTION:
Turning or driving across steep hills can be
dangerous. You could lose traction, slide
sideways, and possibly roll over. You could be
seriously injured or killed. When driving up hills,
always try to go straight up.

Ease up on your speed as you approach the top of
the hill.

Attach a flag to the vehicle to make you more visible
to approaching traffic on trails or hills.

Sound the horn as you approach the top of the hill to
let opposing traffic know you're there.

Use your headlamps even during the day. They make
you more visible to oncoming traffic.
CAUTION:
Driving to the top (crest) of a hill at full speed can
cause an accident. There could be a drop
-off,
embankment, cliff, or even another vehicle. You
could be seriously injured or killed. As you near
the top of a hill, slow down and stay alert.
