Chevrolet 2010 Avalanche Automobile User Manual


 
A high electrical load occurs when several of the
following are on, such as: 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, a Driver Information Center (DIC)
message might be displayed, such as BATTERY
SAVER ACTIVE, BATTERY VOLTAGE LOW, or
LOW BATTERY. 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 457.
Battery Run-Down Protection
This feature shuts off the dome lamps if they are
left on for more than 10 minutes when the ignition is in
LOCK/OFF. This helps to prevent the battery from
running down.
Accessory Power Outlet(s)
The vehicle may have two accessory power outlets
located on the instrument panel and one inside the
center floor console.
The vehicle may also have an outlet on the rear of the
center floor console above the cupholder door.
To use an outlet, remove the protective cap. When not
in use, always cover the outlet with the protective cap.
The accessory power outlet is operational at all times.
Notice: Adding any electrical equipment to the
vehicle can damage it or keep other components
from working as they should. The repairs would not
be covered by the vehicle warranty. Do not use
equipment exceeding maximum amperage rating of
20 amperes. Check with your dealer/retailer before
adding electrical equipment.
Certain power accessory plugs may not be compatible
to the accessory power outlets and could result in blown
vehicle or adapter fuses. If you experience a problem,
see your dealer/retailer for additional information on the
accessory power plugs.
Notice: Improper use of the power outlet can cause
damage not covered by the vehicle warranty. Do not
hang any type of accessory or accessory bracket
from the plug because the power outlets are
designed for accessory power plugs only.
