2007 BUICK LACROSSE change time

You can also select modes by using the
following buttons:
h(Recirculate):Press this button to recirculate
cabin air through the vehicle. It can be used to
help reduce the outside air and odors that
enter your vehicle or to help heat or cool the air
inside your vehicle quicker. An indicator light below
the button will come on in this mode. Operation
in this mode during periods of high humidity
and cool outside temperatures may result in
increased window fogging. If window fogging is
experienced, select the defrost mode. To prevent
the air inside the vehicle from becoming stale,
after ve minutes recirculate will allow some
outside air into the vehicle.
#(Air Conditioning):Press this button to turn
the air conditioning system on or off. When
this button is pressed, an indicator light below the
button will come on to let you know the air
conditioning is activated. Air conditioning can be
selected in any mode as long as the fan switch is
on. The indicator light will change with each
button press even when conditions prevent
operation.On hot days during the vehicle’s initial start-up,
open the windows to let hot inside air escape; then
close them. This helps to reduce the time it
takes for the vehicle to cool down. It also helps
the system to operate more efficiently.
For quicker cool down on hot days, do the
following:
1. Select the vent air mode.
2. Select the recirculation mode.
3. Select the air conditioner.
4. Select the coolest temperature.
5. Select the highest fan speed.
The air conditioning system removes moisture
from the air, so you may sometimes notice a
small amount of water dripping underneath your
vehicle while idling or after turning off the
engine. This is normal.
Using these settings together for long periods
of time may cause the air inside the vehicle to
become too dry. To prevent this, after ve minutes
recirculate will allow some outside air into
the vehicle.

Automatic Operation
AUTO (Automatic):Press the AUTO button for
automatic control of the inside temperature, the air
delivery mode, and the fan speed. There might
be a delay of two to three minutes before the fan
comes on when the automatic operation is
used in cold weather. For the automatic system to
function, the temperature must be set between
61°F (15°C) and 89°F (32°C).
1. Adjust the temperature to a comfortable
setting.
2. Press the PASS button or the up or down
arrows on the passenger side to turn the

reduced fan speeds to avoid blowing cold air
into the vehicle until warmer air is available.
The system will start out blowing air at the oor
but may change modes automatically as the
vehicle warms up to maintain the chosen
temperature setting. The length of time needed
for warm up will depend on the outside
temperature and the length of time that has
elapsed since the vehicle was last driven.
3. Wait for the system to regulate. This may take
from 10 to 30 minutes. Then, adjust the
temperature, if necessary.
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.
4. Press OFF to turn the climate control system
off. Only the rear defog and heated seats will

defrost, or oor/defog modes. Using recirculation
for long periods of time may cause the air
inside your vehicle to become too dry.
Recirculation mode has a ve minute timer after
which the system allows for some fresh outside air
into the vehicle to maintain interior air quality.
#(Air Conditioning):Press this button to turn
the air conditioning compressor on and off.

Fuel Menu Items (Uplevel Only)
.
(Fuel):Press this button to scroll through the
following menu items:
Fuel Range
Press the fuel button until FUEL RANGE displays.
This mode shows the approximate number of
remaining miles or kilometers the vehicle can be
driven without refueling.
Fuel range is based on several factors, including
distance traveled, fuel used, fuel capacity, etc.
This estimate will change if driving conditions
change. For example, if driving in traffic and
making frequent stops, this mode may read
one number, but if the vehicle is driven on a
freeway, the number may change even though the
same amount of fuel is in the fuel tank. This is
because different driving conditions produce
different fuel economies. Generally, freeway
driving produces better fuel economy than city
driving. Fuel range cannot be reset.
If your vehicle is low on fuel, FUEL RANGE LOW
will display followed by the LOW FUEL message.
See “LOW FUEL” underDIC Warnings and
Messages on page 208for more information.
Average Fuel Economy
Press the fuel button until AVG ECONOMY
displays. This mode shows the approximate
average miles per gallon (mpg) or liters per
100 kilometers (L/100 km). This number is
calculated based on the number of mpg (L/100 km)
recorded since the last time this menu item was
reset. To reset AVG ECONOMY, press and hold
the set/reset button. The display will return to zero.

your vehicle. If this consistently occurs, see
your dealer for service.
Oil Life
Press the gages button until OIL LIFE displays.
This mode shows an estimate of the oil’s
remaining useful life. If you see OIL LIFE 99% on
the display, that means 99% of the current oil
life remains. The engine oil life system will alert
you to change your oil on a schedule consistent
with your driving conditions.
When the remaining oil life is low, the CHANGE OIL
SOON message will appear on the display. You
should change your oil as soon as possible. See
Engine Oil on page 353. In addition to the engine oil
life system monitoring the oil life, additional
maintenance is recommended in the Maintenance
Schedule in this manual. SeeScheduled
