2010 HUMMER H3 stop start

Instruments and Controls 5-15
If the light comes on while driving,
pull off the road and stop. The brake
pedal might be harder to push, or it
might go closer to the floor. It can
take longer to stop. If the light is
still on, have the vehicle towed for
service. SeeTowing the Vehicle
on
page 10‑90.
{WARNING
The brake system might not be
working properly if the brake
system warning light is on.
Driving with the brake system
warning light on can lead to a
crash. If the light is still on after
the vehicle has been pulled off
the road and carefully stopped,
have the vehicle towed for
service.
Antilock Brake System
(ABS) Warning Light
For vehicles with the Antilock Brake
System (ABS), this light comes on
briefly when the engine is started.
If it does not, have the vehicle
serviced by your dealer. If the
system is working normally the
indicator light will then go off.
If the ABS light stays on, turn the
ignition off. If the light comes on
while driving, stop as soon as it is
safely possible and turn the ignition
off. Then start the engine again to
reset the system. If the ABS light
stays on, or comes on again while
driving, the vehicle needs service.
If the regular brake system warning
light is not on, the vehicle still has
brakes, but not antilock brakes. If the regular brake system warning
light is also on, the vehicle does not
have antilock brakes and there is a
problem with the regular brakes.
See
Brake System Warning Light
on page 5‑14.
For vehicles with a Driver
Information Center (DIC), see
Brake System Messages
on
page 5‑22for more information.
Up-Shift Light
The vehicle may have an up-shift
light.
When this light comes on, shift to
the next higher gear if weather,
road, and traffic conditions allow.
See Manual Transmission
on
page 9‑44for more information.

5-16 Instruments and Controls
Traction Control System
(TCS)/StabiliTrak®Light
The StabiliTrak system or the
Traction Control System (TCS)
indicator/warning light comes on
briefly while starting the engine.
If it does not, have the vehicle
serviced by your dealer. If the
system is working normally the
indicator light will then go off.
The indicator/warning light flashes
while the StabiliTrak or TCS system
is working to control the vehicle on
a low traction surface.
If the TCS warning light comes on
and stays on while driving, the
vehicle needs service.The light comes on when the TCS
and the StabiliTrak system is turned
off. If the TCS is off, wheel spin is
not limited. If the StabiliTrak system
is off, the system does not assist in
controlling the vehicle. Turn on the
TCS and the StabiliTrak system and
the warning light turns off.

StabiliTrak System
on
page 9‑53and Traction Control
System (TCS)on page 9‑52for
more information
Tire Pressure Light
For vehicles with a tire pressure
monitoring system, this light comes
on briefly when the engine is
started. It provides information
about tire pressures and the Tire
Pressure Monitoring System. When the Light is On Steady
This indicates that one or more
of the tires are significantly
underinflated.
A tire pressure message in the
Driver Information Center (DIC),
can accompany the light. See
Tire
Messages
on page 5‑25for
more information. Stop as soon as
possible, and inflate the tires to the
pressure value shown on the tire
loading information label. See Tire
Pressure
on page 10‑51for more
information.
When the Light Flashes First and
Then is On Steady
This indicates that there may be
a problem with the Tire Pressure
Monitor System. The light flashes
for about a minute and stays on
steady for the remainder of the
ignition cycle. This sequence
repeats with every ignition cycle.
See Tire Pressure Monitor
Operation
on page 10‑53for
more information.

7-10 Infotainment System
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.

9-6 Driving and Operating
Turn the steering wheel 8 to 13 cm
(3 to 5 inches), about one-eighth
turn, until the right front tire contacts
the pavement edge. Then turn the
steering wheel to go straight down
the roadway.
Loss of Control
Let us review what driving experts
say about what happens when the
three control systems—brakes,
steering, and acceleration —do not
have enough friction where the tires
meet the road to do what the driver
has asked.
In any emergency, do not give up.
Keep trying to steer and constantly
seek an escape route or area of
less danger.
Skidding
In a skid, a driver can lose control of
the vehicle. Defensive drivers avoid
most skids by taking reasonable
care suited to existing conditions,
and by not overdriving those
conditions. But skids are always
possible.
The three types of skids correspond
to the vehicle's three control
systems. In the braking skid, the
wheels are not rolling. In the
steering or cornering skid, too much
speed or steering in a curve causes
tires to slip and lose cornering force.
And in the acceleration skid, too
much throttle causes the driving
wheels to spin.
If the vehicle starts to slide, ease
your foot off the accelerator pedal
and quickly steer the way you
want the vehicle to go. If you start
steering quickly enough, the vehicle
may straighten out. Always be ready
for a second skid if it occurs. Of course, traction is reduced when
water, snow, ice, gravel, or other
material is on the road. For safety,
slow down and adjust your driving to
these conditions. It is important to
slow down on slippery surfaces
because stopping distance is longer
and vehicle control more limited.
While driving on a surface with
reduced traction, try your best to
avoid sudden steering, acceleration,
or braking, including reducing
vehicle speed by shifting to a lower
gear. Any sudden changes could
cause the tires to slide. You might
not realize the surface is slippery
until the vehicle is skidding. Learn to
recognize warning clues
—such as
enough water, ice, or packed snow
on the road to make a mirrored
surface —and slow down when you
have any doubt.
Remember: Antilock brakes help
avoid only the braking skid.

Driving and Operating 9-13
Scanning the Terrain
Off-road driving can take you over
many different kinds of terrain. Be
familiar with the terrain and its many
different features.
Surface Conditions:Off-roading
surfaces can be hard-packed dirt,
gravel, rocks, grass, sand, mud,
snow, or ice. Each of these surfaces
affects the vehicle's steering,
acceleration, and braking in different
ways. Depending on the surface,
slipping, sliding, wheel spinning,
delayed acceleration, poor traction,
and longer braking distances can
occur. Surface Obstacles:
Unseen or
hidden obstacles can be hazardous.
A rock, log, hole, rut, or bump can
startle you if you are not prepared
for them. Often these obstacles are
hidden by grass, bushes, snow,
or even the rise and fall of the
terrain itself.
Some things to consider:
.Is the path ahead clear?
.Will the surface texture change
abruptly up ahead?
.Does the travel take you uphill or
downhill?
.Will you have to stop suddenly
or change direction quickly?
When driving over obstacles or
rough terrain, keep a firm grip on
the steering wheel. Ruts, troughs,
or other surface features can jerk
the wheel out of your hands. When driving over bumps, rocks,
or other obstacles, the wheels can
leave the ground. If this happens,
even with one or two wheels, you
cannot control the vehicle as well or
at all.
Because you will be on an unpaved
surface, it is especially important to
avoid sudden acceleration, sudden
turns, or sudden braking.
Off-roading requires a different kind
of alertness from driving on paved
roads and highways. There are no
road signs, posted speed limits,
or signal lights. Use good judgment
about what is safe and what is not.

Driving and Operating 9-15
{WARNING
Many hills are simply too steep
for any vehicle. If you drive up
them, you will stall. If you drive
down them, you cannot control
your speed. If you drive across
them, you will roll over. You could
be seriously injured or killed.
If you have any doubt about the
steepness, do not drive the hill.
Approaching a Hill
When you approach a hill, decide if
it is too steep to climb, descend,
or cross. Steepness can be hard to
judge. On a very small hill, for
example, there may be a smooth,
constant incline with only a small
change in elevation where you can
easily see all the way to the top.
On a large hill, the incline may get
steeper as you near the top, but you
might not see this because the crest
of the hill is hidden by bushes,
grass, or shrubs.Consider this as you approach a hill:
.Is there a constant incline,
or does the hill get sharply
steeper in places?
.Is there good traction on the
hillside, or will the surface cause
tire slipping?
.Is there a straight path up or
down the hill so you will not
have to make turning
maneuvers?
.Are there obstructions on the hill
that can block your path, such
as boulders, trees, logs, or ruts?
.What is beyond the hill? Is there
a cliff, an embankment, a
drop-off, a fence? Get out and
walk the hill if you do not know.
It is the smart way to find out.
.Is the hill simply too rough?
Steep hills often have ruts,
gullies, troughs, and exposed
rocks because they are more
susceptible to the effects of
erosion.See
Hill Start Assist (HSA)
on
page 9‑52for information on
vehicles stopped on a grade.
Driving Uphill
Once you decide it is safe to drive
up the hill:
.Use transmission and transfer
case low gear and get a firm grip
on the steering wheel.
.Get a smooth start up the hill
and try to maintain speed. Not
using more power than needed
can avoid spinning the wheels or
sliding.
.Let the traction system work to
control any wheel slippage. The
traction control system allows for
moderate wheel spin with some
capability to dig in and power up
the hill.
