{CAUTION:
If your vehicle has four-wheel drive, it will
be free to roll — even if the shift lever is
in PARK (P) — if the transfer case is in
NEUTRAL. So be sure the transfer case
is in a drive gear — not in NEUTRAL.
SeeFour-Wheel Drive on page 121.
Follow the proper steps to be sure your vehicle
will not move. SeeShifting Into Park (P) on

Mirrors
Manual Rearview Mirror
Your vehicle may have this feature. While sitting in
a comfortable driving position, adjust the rearview
mirror so you can see clearly behind your
vehicle. Grip the mirror in the center to move it up
or down and side to side. The day/night control,
located at the bottom of the mirror, adjusts
the mirror to reduce headlamp glare from behind
during evening or dark conditions. Turn the
control clockwise for night use; return it to the
center for daytime use.
Manual Rearview Mirror with OnStar®
Your vehicle may have a rearview mirror with the
OnStar®system.
Control buttons for the OnStar
®system are at the
bottom of the mirror. See your dealer for more
information on the OnStar
®system and how
to subscribe to OnStar®. Also, seeOnStar®
System on page 145for more information about
the services OnStar®provides.

Headlamps on Reminder
A reminder tone sounds when the headlamps
or parking lamps are manually turned on, if
the driver’s door is open and the ignition is in
LOCK or ACC. To turn the tone off, turn the
knob all the way counterclockwise.
In the automatic mode, the headlamps turn off
once the ignition key is in LOCK.
Daytime Running Lamps (DRL)
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. Fully functional DRL are required on all
vehicles  rst sold in Canada.
The DRL system makes the headlamps come
on at reduced brightness when the following
conditions are met:
The ignition is on.
The exterior lamps knob is in automatic
headlamp mode.
The light sensor detects daytime light.
The transmission is not in PARK (P).
When the DRL are on, only the headlamps will
be on. The taillamps, sidemarker and other lamps
will not be on. The instrument panel will not be
lit up either.
When it begins to get dark, the headlamps
automatically switch from DRL to the regular
headlamps.
