2010 HUMMER H3 light

Lighting 6-9
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 one of these messages displays,
it is recommended that the driver
reduce the electrical loads as much
as possible. See
Driver Information
Center (DIC) on page 5‑18.Battery Power Protection
The dome lamp is shut off if it is left
on for more than 20 minutes when
the ignition is in LOCK/OFF. This
helps to prevent the battery from
being drained.

Fixed Mast Antenna
The fixed mast antenna can
withstand most car washes without
being damaged as long as it is
securely attached to the base.
If the mast becomes slightly bent,
straighten it out by hand. If the mast
is badly bent, replace it.
Occasionally check to make sure
the antenna is tightened to its base.
If tightening is required, tighten
by hand until fully seated plus
one quarter turn.
Satellite Radio Antenna
The XM Satellite Radio antenna is
located on the roof of the vehicle.
Keep the antenna clear of
obstructions for clear radio
reception.
If the vehicle has a sunroof, the
performance of the XM system may
be affected if the sunroof is open.
Audio Players
CD Player
The CD player can play smaller
8 cm (3 in) single CDs with an
adapter ring.
A CD in the player it stays in the
player when the ignition is turned
off. When the ignition or radio is
turned on, the CD starts to play
where it stopped, if it was the last
selected audio source.
Care of CDs
Store CDs in their original cases or
other protective cases and away
from direct sunlight and dust. The
CD player scans the bottom of
the disc. If the bottom of a CD is
damaged it may not play properly or
at all. Do not touch the bottom of a
CD while handling it. Pick up CDs
by grasping the outer edges or the
edge of the hole and the outer edge.
If the surface of a CD is dirty, take
a soft, lint free cloth or dampen a
clean, soft cloth in a mild, neutraldetergent solution mixed with water,
and clean it. Make sure the wiping
process starts from the center to
the edge.
Care of the CD Player
Do not add labels to a CD, it could
get caught in the CD player. Use a
marking pen to write on the top of
the CD if a description is needed.
Do not use CD lens cleaners, they
could damage the CD player.
Notice:
If a label is added to a
CD, or more than one CD is
inserted into the slot at a time,
or an attempt is made to play
scratched or damaged CDs, the
CD player could be damaged.
While using the CD player, use
only CDs in good condition
without any label, load one CD at
a time, and keep the CD player
and the loading slot free of
foreign materials, liquids, and
debris.
If an error displays, see “CD
Messages” later in this section.

similar to the defogger grid.

Driving and Operating 9-3
Death and injury associated with
drinking and driving is a global
tragedy.
Alcohol affects four things that
anyone needs to drive a vehicle:
judgment, muscular coordination,
vision, and attentiveness.
Police records show that
almost 40 percent of all motor
vehicle-related deaths involve
alcohol. In most cases, these
deaths are the result of someone
who was drinking and driving.
In recent years, more than
17,000 annual motor vehicle-related
deaths have been associated with
the use of alcohol, with about
250,000 people injured.
For persons under 21, it is against
the law in every U.S. state to drink
alcohol. There are good medical,
psychological, and developmental
reasons for these laws.
The obvious way to eliminate the
leading highway safety problem is
for people never to drink alcohol
and then drive.Medical research shows that
alcohol in a person's system
can make crash injuries worse,
especially injuries to the brain,
spinal cord, or heart. This means
that when anyone who has been
drinking
—driver or passenger —is
in a crash, that person's chance of
being killed or permanently disabled
is higher than if the person had not
been drinking.
Control of a Vehicle
The following three systems
help to control the vehicle while
driving —brakes, steering, and
accelerator. At times, as when
driving on snow or ice, it is easy to
ask more of those control systems
than the tires and road can provide.
Meaning, you can lose control of
the vehicle. See Traction Control
System (TCS)
on page 9‑52and
StabiliTrak System on page 9‑53. Adding non‐dealer/non‐retailer
accessories can affect vehicle
performance. See
Accessories and
Modifications on page 10‑3.
Braking
See Brake System Warning Lighton page 5‑14.
Braking action involves perception
time and reaction time. Deciding to
push the brake pedal is perception
time. Actually doing it is
reaction time.
Average reaction time is about
three‐fourths of a second. But that is
only an average. It might be less
with one driver and as long as
two or three seconds or more with
another. Age, physical condition,
alertness, coordination, and
eyesight all play a part. So do
alcohol, drugs, and frustration. But
even in three‐fourths of a second,
a vehicle moving at 100 km/h
(60 mph) travels 20 m (66 ft).
