trunk BUICK LACROSSE 2007 User 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.
164

The rst time an object is detected while in
REVERSE (R), a chime will sound and the
following will occur in sequence, depending on the
distance from the object:
At 5 feet (1.5 m) a chime will sound and
one amber light will be lit.
At 40 inches (1.0 m) both amber lights will
be lit.
At 20 inches (0.5 m) a continuous chime will
sound and all three lights (amber/amber/red)
will be lit.
At 1 foot (0.3 m) a continuous chime will
sound and all three lights (amber/amber/red)
will ash.
URPA can detect objects 3 inches (7.6 cm) and
wider, and at least 10 inches (25.4 cm) tall,
but it cannot detect objects that are above trunk
level. In order for the rear sensors to recognize an
object, it must be within operating range.
If the URPA system is not functioning properly, the
display will ash red, indicating that there is a
problem. The light will also ash red while driving if
a trailer is attached to your vehicle, or a bicycle or
object is on the back of, or hanging out of yourtrunk. The light will continue to ash until the trailer
or the object is removed and your vehicle is driven
forward at least 15 mph (25 km/h).
It may also ash red if the ultrasonic sensors are
not kept clean. So be sure to keep your rear
bumper free of mud, dirt, snow, ice and slush or
materials such as paint or the system may
not work properly. If after cleaning the rear bumper
and driving forward at least 15 mph (25 km/h),
the display continues to ash red, see your
GM dealer. For cleaning instructions, seeWashing
Your Vehicle on page 442.
It may also ash red if your vehicle is moving in
REVERSE (R) at a speed greater than 3 mph
(5 km/h). Other conditions that may affect system
performance include things like the vibrations
from a jackhammer or the compression of
airbrakes on a very large truck.
As always, drivers should use care when backing
up a vehicle. Always look behind you, being
sure to check for other vehicles, obstructions and
blind spots.
