seats BUICK LACROSSE 2007 Owner's Guide

A high electrical load occurs when several of the
following loads are on: headlamps, high beams,
fog lamps, rear window defogger, climate
control fan at high speed, heated seats, engine
cooling fans, trailer loads, and loads plugged into
accessory power outlets.
EPM works to prevent excessive discharge of the
battery. It does this by balancing the generator’s
output and the vehicle’s electrical needs. It
can increase engine idle speed to generate more
power, whenever needed. It can temporarily
reduce the power demands of some accessories.
Normally, these actions occur in steps or levels,
without being noticeable. In rare cases at the
highest levels of corrective action, this action may
be noticeable to the driver. If so, the Driver
Information Center (DIC) message might display
Battery Saver Active. If this message is displayed,
it is recommended that the driver reduce the
electrical loads as much as possible. See
DIC Warnings and Messages on page 208.Battery Run-Down Protection
This helps prevent the vehicle’s battery from
draining in case the interior courtesy lamps,
reading lamps, trunk lamp, underhood lamp, glove
box lamps, or sun visor vanity lamps, if equipped,
are accidently left on. If any of these lamps
are left on while the ignition is off, they will
automatically turn off after 10 minutes. The lamps
will not come back on again until one of the
following occurs:
The ignition is turned on.
The interior lamps control is turned off, then to
door or on.
Ultrasonic Rear Parking
Assist (URPA)
Your vehicle may be equipped with Ultrasonic Rear
Parking Assist (URPA). URPA is designed to help
you park while in REVERSE (R) and operates only
at speeds less than 3 mph (5 km/h). URPA can help
you avoid colliding with objects such as parked
vehicles. The system can detect objects 5 feet
(1.5 m) behind your vehicle and tell you how close
those objects are to your rear bumper.

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
passenger temperature set on and off. When
turned on, the passenger temperature will
be the same as the driver setting. Press the
up or down arrow on passenger side to adjust
the passenger temperature setting.
When the passenger’s temperature set is off,
the passenger display will be off and the
driver’s set temperature will be for the driver
and passenger.In cold weather, the system will start at
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
function. Press AUTO or any other button
except the heated seats or rear defog to turn
the climate control system back on.

instrument panel outlets.
h(Recirculation):Press this button to turn
recirculation mode on or off. This mode keeps
outside air from coming into the vehicle. It can be
used to help reduce the outside air and odors
that enter your vehicle or help cool the air inside
the vehicle quicker.
Recirculation is not available while in the oor,
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.
The indicator light on the button will come on
when the air conditioning is on. The indicator light
will change with each button press even when

remove fog or frost from the rear window. The
rear window defogger will only work when
the engine is running.
=(Rear Window Defogger):Press this button
to turn the rear window defogger on and off.
Be sure to clear as much snow from the rear
window as possible.
The rear window defogger will turn off about
20 minutes after the button is pressed. If turned
on again, the defogger will only run for about
20 minutes before turning off. The defogger can
also be turned off by pressing the button again or
by turning off the engine.
Do not drive the vehicle until all the windows
are clear.
Notice:Do not use a razor blade or sharp
object to clear the inside rear window. Do not
adhere anything to the defogger grid lines
in the rear glass. These actions may damage
the rear defogger. Repairs would not be
covered by your warranty.

SeePassenger Sensing System on page 75for
more on this, including important safety
information.
If, after several seconds, all status indicator lights
remain on, or if there are no lights at all, there
may be a problem with the lights or the passenger
sensing system. See your dealer for service.
{CAUTION:
If the off indicator and the airbag
readiness light ever come on together, it
means that something may be wrong with
the airbag system. If this ever happens,
have the vehicle serviced promptly,
because an adult-size person sitting in the
right front passenger seat may not have
the protection of the frontal airbag. See
Airbag Readiness Light on page 182.
Charging System Light
This light comes on
briey when the ignition
is turned on, as a
check to show that it is
working. Then it
should go out.
If it stays on, or comes on while the vehicle is being
driven, a chime will sound and there may be a
problem with the charging system. It could indicate
that the vehicle has a loose accessory belt or
another electrical problem. Have it checked right
away. Driving while this light is on could drain the
battery and result in the engine suddenly stopping.
If the vehicle must be driven a short distance with
the light on, be certain to turn off all unnecessary
electrical loads, such as the radio, heater fan,
air conditioning fan, and heated seats.
