2-41 Headlamps-On Reminder
A buzzer will sound when your headlamps are turned on
and your ignition is in OFF, LOCK or ACCESSORY. If
you need to use your headlamps when the ignition
switch is in OFF, LOCK or ACCESSORY, the buzzer
can be turned off by turning the thumbwheel next to the
parking and headlamp switch all the way down.
Daytime Running Lamps
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the day.
DRL can be helpful in many different driving
conditions, but they can be especially helpful in the
short periods after dawn and before sunset.
The DRL system will make your headlamps come on at
a reduced brightness when:

the ignition is on,

the headlamp switch is off and

the parking brake is released.
When the DRL are on, only your headlamps will be on.
The taillamps, sidemarker and other lamps won't be on.
Your instrument panel won't be lit up either.When it begins to get dark, your DRL indicator light
is a reminder to turn your headlamp switch on. The
other lamps that come on with your headlamps will also
come on.
When you turn the headlamp switch off, the regular
lamps will go off, and your headlamps will change to
the reduced brightness of DRL.
To idle your vehicle with the DRL off, set the parking
brake. The DRL will stay off until you release the
parking brake.
As with any vehicle, you should turn on the regular
headlamp system when you need it.

2-47 Electrochromic Inside Rearview Mirror
with Compass and Temperature Display
(If Equipped)
Your vehicle may have electrochromic inside and
outside rearview mirrors.
When on, an electrochromic mirror automatically dims
to the proper level to minimize glare from lights behind

The mirror also includes a display in the upper right
corner of the mirror face. This can be used as a compass
or to indicate outside air temperature.
Temperature Display
The temperature can be displayed by pressing the
TEMP side of the switch. Pressing the TEMP switch
once briefly, will toggle the temperature reading on and
off. To alternate the temperature reading between
Fahrenheit and Celsius, press and hold the TEMP button
for three seconds until the display blinks F

If an abnormal reading is displayed, please consult
your dealer.
Electrochromic Mirror Operation
The right side of the switch, labeled TEMP, located at
the bottom of the mirror turns the electrochromic inside
and outside mirrors on and off. An indicator light,
located to the right of the TEMP switch, will come on
when the electrochromic mirrors are turned on. To turn
the mirrors on, press and hold the TEMP button for six
seconds. To turn the mirrors off, press and hold the
TEMP button for six seconds. The indicator light will
turn off.
Compass Operation
Press the COMP switch once briefly to turn the compass
on or off.
When the ignition and the compass feature are on, the
compass will show two character boxes for
approximately two seconds. After two seconds, the
mirror will display the compass heading.When cleaning the mirror, use a paper towel or similar
material dampened with glass cleaner. Do not spray
glass cleaner directly on the mirror as that may cause the
liquid cleaner to enter the mirror housing.
Compass Calibration
If, after two seconds, the display does not show a
compass heading (ªNº for North, for example), there
may be a strong magnetic field interfering with the
compass. Such interference may be caused by a
magnetic antenna mount, magnetic note pad holder
or a similar magnetic item. If the letter ªCº should ever
appear in the compass window, the mirror may
need calibration.
The mirror can be calibrated in one of two ways:

Drive the vehicle in circles at five mph (8 km/h) or
less until the display reads a direction, or

Drive the vehicle on your everyday routine and after
several turns the compass will become calibrated and
will display a direction.

Be sure the cargo is properly loaded.

If small heavy objects are placed on the roof, place
the load in the area over the rear wheels (behind the
rear side door on Suburbans). If you need to, cut a
piece of 3/8 inch plywood to fit inside the crossrails
and side rails to spread the load. If plywood is used,
tie it to the side rail supports.

Tie the load to the crossrails or the side rail supports.
Use the crossrails only to keep the load from sliding.

If you need to carry long items, move the crossrails
as far apart as they will go. Tie the load to the
crossrails and the side rails or side rail supports. Also
tie the load to the bumpers. Do not tie the load so
tightly that the crossrails or side rails are damaged.

For the purpose of wind noise reduction, locate the
front crossrail approximately 18 to 24 inches
(46 cm to 58 cm) rearward of the front supports.

After moving the crossrails, be sure to tighten all the
slider screws.
Your vehicle has a Center High
-Mounted Stoplamp
(CHMSL) located above the tailgate glass or above the
rear load doors.
If items are loaded on the roof of the vehicle, care should
be taken not to block or damage the CHMSL unit.
