Delayed Locking
This feature allows the driver to delay the actual locking
of the doors. When the driver’s power door lock
switch is pressed with the key removed from the ignition,
and the driver’s door open, a chime will sound three
times to signal that the delayed locking system is active.
When all doors have been closed, the doors will lock
automatically after several seconds. If any door is
opened before this, the timer will reset itself once all the
doors have been closed again.
Pressing the driver’s or passenger’s power door lock
switch again or the remote keyless entry transmitter
button will override this feature.
Personal Choice Programming
The delayed locking feature can be turned on or off,
using the Driver Information Center (DIC) to program
this feature. See “DELAY DOOR LOCK” underDIC
Vehicle Customization on page 3-66.
Programmable Automatic
Door Locks
Your vehicle is programmed so that, when the doors are
closed, the ignition is on, and the shift lever is moved
out of PARK (P), all the doors will lock. The doors
will unlock every time you stop the vehicle and move
the shift lever into PARK (P).
If someone needs to get out while your vehicle is not in
PARK (P), have the person use the manual lock
knob or power door lock switch. When the door is closed
again, it will not lock automatically. Use the manual
lock knob or power door lock switch to lock the door.
If your vehicle has a Driver Information Center
(DIC), you can choose various lock and unlock settings.
For programming information, seeDIC Vehicle
Customization on page 3-66.

up to 20 seconds for each of the remaining cycles.
The heated windshield washer uid system may
be turned off at any time by sliding the switch on the
turn signal/multifunction lever to this position again.
When the heated windshield washer uid system
is activated under certain outside temperature
conditions, steam may ow out of the washer nozzles
for a short period of time before washer uid is sprayed.

Automatic Operation
AUTO (Automatic Fan):When AUTO is selected on
the fan control, the system automatically adjusts the fan
speed. If the OnStar
®system is activated when this
position is selected, the fan speed will lower.
AUTO (Automatic Mode)
1. Turn the fan control to AUTO.
2. Turn the mode control to AUTO.
3. Adjust the temperature to a comfortable setting
between 68°F (21°C) and 78°F (26°C).
Choosing the coldest or warmest temperature
setting will not cause the system to heat or cool any
faster. In cold weather, the system starts at
reduced fan speeds to avoid blowing cold air into
the vehicle until warmer air is available. The system
will start out blowing air to the oor, but may
change modes automatically as the vehicle warms
up to maintain the chosen temperature setting.
The length of time needed to warm the interior
depends on the outside temperature.
4. Wait a few minutes for the system to automatically
regulate. Then adjust the temperature as necessary
to nd your comfort setting.
Do not cover the solar sensor located in the center of
the instrument panel, near the windshield. For more
information on the solar sensor, see “Sensors” later in
this section.After the vehicle is started, the display shows the
interior temperature settings.
When the ENG/MET (English/metric) button on the
Driver Information Center (DIC) is pressed, the display
shows readings in Fahrenheit or Celsius. Use the
ENG/MET button to toggle between the readings.
AUTO (Automatic Air Conditioning):If AUTO is
selected on the fan or mode control, the system
automatically controls the air conditioning compressor.
The A/C compressor runs automatically even at cool
outside temperatures in order to dehumidify the air. The
A/C indicator light is lit when the system is operating
automatically. Press the A/C button on the fan control to
turn off the A/C. To clear windows better in defog or
defrost modes, the A/C compressor runs automatically
in damp cool conditions.
h(Auto Recirculation):If AUTO is selected on
either the fan or mode control, the system automatically
controls the supply of fresh outside air or recirculates
the interior air to cool the car faster. The indicator
light on the recirculation button will light whenever the
system switches to recirculation. You may force outside
air by pressing the outside air button. The next time
AUTO fan or mode is selected, it will reset back
to AUTO operation.

Speedometer and Odometer
Your speedometer lets you see your speed in both
miles per hour (mph) and kilometers per hour (km/h).
Your odometer shows how far your vehicle has
been driven, in either miles or kilometers.
Your vehicle has a tamper resistant odometer.
You may wonder what happens if your vehicle needs a
new odometer installed. If the new one can be set to
the mileage total of the old odometer, then it must
be. But if it cannot, then it is set at zero and a label must
be put on the driver’s door to show the old mileage
reading when the new odometer was installed.
Trip Odometer
A trip odometer can tell you how far you have driven
since you last set it to zero. SeeDriver Information
Center (DIC) on page 3-48for information on resetting
the trip odometer.
Tachometer
Your tachometer displays the engine speed in
revolutions per minute (rpm).
Safety Belt Reminders
Safety Belt Reminder Light
When the engine is started, a chime will come on for
several seconds to remind people to fasten their safety
belts, unless the driver’s safety belt is already buckled.
The safety belt light will
also come on and stay on
for several seconds, then it
will ash for several more.
This chime and light is repeated if the driver remains
unbuckled and the vehicle is in motion. If the driver’s belt
is already buckled, neither the chime nor the light will
come on.

Antilock Brake System
Warning Light
For vehicles with the
Antilock Brake System
(ABS), this light will come
on briey when you

If the ABS light stays on, turn the ignition off, if the light
comes on when you are driving, stop as soon as it
is safely possible and turn the ignition off. Then start the
engine again to reset the system. If the ABS light still
stays on, or comes on again while you are driving, your
vehicle needs service. If the regular brake system
warning light is not on, you still have brakes, but you do
not have antilock brakes. If the regular brake system
warning light is also on, you do not have antilock brakes
and there is a problem with your regular brakes. See
Brake System Warning Light on page 3-39
For vehicles with a Driver Information Center (DIC), see
DIC Warnings and Messages on page 3-56for all
brake related DIC messages.
