Pontiac 2004 Bonneville - Manual (Page 142)

Battery Load Management
The battery load management feature is designed to
monitor the vehicle’s electrical load and determine when
the battery is in a heavy discharge condition. During
times of high electrical loading, the engine may idle at
higher revolutions per minute (RPM) than normal to make
sure the battery charges. High electrical loads may occur
when several of the following are on: headlamps, high
beams, fog lamps, rear window defogger, fan on high
speed, heated seats and engine cooling fans.
If your vehicle’s battery remains in a heavy discharge
condition for a long period of time, the fan, rear
defogger, heated seats and heated mirrors will be
disabled and the DIC will display BATTERY SAVER
ACTIVE. This can happen either under long periods of
idling or low speed driving with high electrical loading,
or in the event of a charging system fault.
Monitor the battery voltage when in the BATTERY
SAVER ACTIVE mode.
• If the voltmeter remains in the shaded area (below
11 volts) when driving then have the charging
system serviced immediately.
• If the voltage increases above 12 volts then the
battery needs to be recharged. Try driving on
the highway with as few electrical accessories on
as possible.
Head-Up Display (HUD)
{ CAUTION:
If the HUD image is too bright, or too high in
your field of view, it may take you more time to
see things you need to see when it is dark
outside. Be sure to keep the HUD image dim
and placed low in your field of view.
If you have the optional Head-Up Display (HUD), you
can see some of the driver information also available on
your instrument panel cluster. The information may
be displayed in English or metric units and appears as a
reflection on the windshield. The HUD shows the
following:
• Speedometer Reading
• Turn Signal Indicators
• High-beam Indicator Symbol
• CHECK GAGES Message (for low oil pressure,
high coolant temperature, low oil level, high/low
battery, brake, ABS and air bag)
• Low Fuel Warning Symbol
• Radio Frequency and Playback Mode (with the
exception of the XM™ radio)
