2010 CHEVROLET SILVERADO warning

Cruise Control
{WARNING:
Cruise control can be dangerous where you
cannot drive safely at a steady speed. So, do not
use the cruise control on winding roads or in
heavy traffic.
Cruise control can be dangerous on slippery
roads. On such roads, fast changes in tire traction
can cause excessive wheel slip, and you could
lose control. Do not use cruise control on slippery
roads.
For vehicles with cruise control, a speed of about
40 km/h (25 mph) or more can be maintained without
keeping your foot on the accelerator. Cruise control
does not work at speeds below about 40 km/h (25 mph). When the brakes are applied, cruise control is
turned off.
For vehicles with an Allison
®or Hydra‐Matic 6‐speed
automatic transmission, see “Grade Braking and Cruise
Grade Braking (Allison Transmission) under Tow/Haul
Mode
on page 3‑34for an explanation of how cruise
control interacts with the Range Selection Mode, tow/
haul and grade braking systems.
For vehicles with the StabiliTrak
®system that begins to
limit wheel spin while you are using cruise control, the
cruise control will automatically disengage. See
StabiliTrak
®Systemon page 5‑6. When road
conditions allow the cruise control to be safely used
again, it can be turned back on.

Electric Power Management
The vehicle has Electric Power Management (EPM) that
estimates the battery's temperature and state of charge.
It then adjusts the voltage for best performance and
extended life of the battery.
When the battery's state of charge is low, the voltage is
raised slightly to quickly bring the charge back up.
When the state of charge is high, the voltage is lowered
slightly to prevent overcharging. If the vehicle has a
voltmeter gauge or a voltage display on the Driver
Information Center (DIC), you may see the voltage
move up or down. This is normal. If there is a problem,
an alert will be displayed.
The battery can be discharged at idle if the electrical
loads are very high. This is true for all vehicles. This is
because the generator (alternator) may not be spinning
fast enough at idle to produce all the power that is
needed for very high electrical loads.
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 4‑63.
Battery Run-Down Protection
This feature shuts off the dome and reading lamps,
if they are left on for more than 10 minutes after the
ignition is turned off. The cargo lamp shuts off after
20 minutes. This prevents the battery from
running down.
4-16

Outlet Adjustment
Use the air outlets located in the center and on the side
of the instrument panel to direct the airflow. Use the
thumbwheels near the air outlets to open or close off
the airflow.
Operation Tips
.Clear away any ice, snow, or leaves from air inlets
at the base of the windshield that could block the
flow of air into the vehicle.
.Keep the path under the front seats clear of
objects to help circulate the air inside of the vehicle
more effectively.
.Use of non‐GM approved hood deflectors can
adversely affect the performance of the system.
Check with your dealer before adding equipment to
the outside of the vehicle.
Warning Lights, Gauges, and
Indicators
Warning lights and gauges can signal that something is
wrong before it becomes serious enough to cause an
expensive repair or replacement. Paying attention to the
warning lights and gauges could prevent injury.
Warning lights come on when there might be or there is
a problem with one of the vehicle's functions. Some
warning lights come on briefly when the engine is
started to indicate they are working.
Gauges can indicate when there might be or there is a
problem with one of the vehicle's functions. Often
gauges and warning lights work together to indicate a
problem with the vehicle.
When one of the warning lights comes on and stays on
while driving, or when one of the gauges shows there
could be a problem, check the section that explains
what to do. Follow this manual's advice. Waiting to do
repairs can be costly and even dangerous.

Safety Belt Reminders
Driver Safety Belt Reminder Light
When the engine is started, a chime sounds for
several seconds to remind a driver to fasten the safety
belt, unless the driver safety belt is already buckled.
The safety belt
light flashes for
several seconds, then
comes on solid for
several more.
This chime and light sequence are repeated if the driver
remains unbuckled and the vehicle is in motion. If the
driver safety belt is already buckled, neither the chime
nor the light comes on.
Passenger Safety Belt Reminder Light
For vehicles equipped with the passenger safety belt
reminder light, several seconds after the engine is
started, a chime sounds for several seconds to remind
the front passenger to buckle their safety belt. The
passenger safety belt light, located on the overhead
console, comes on and stays on for several seconds,
flashes for several more seconds and then comes on
solid for several more.
This chime and light
sequence is repeated if
the passenger remains
unbuckled and the vehicle
is in motion.
If the passenger safety belt is buckled, neither the
chime nor the light comes on.
The front passenger safety belt warning light and chime
may turn on if an object is put on the seat such as a
briefcase, handbag, grocery bag, laptop or other
electronic device. To turn off the warning light and or
chime, remove the object from the seat or buckle the
safety belt.

Airbag Readiness Light
The system checks the airbag's electrical system for
possible malfunctions. If the light stays on it indicates
there is an electrical problem. The system check
includes the airbag sensor, the pretensioners, the
airbag modules, the wiring and the crash sensing and
diagnostic module. For more information on the airbag
system, seeAirbag System on page 2‑73.
The airbag readiness light
comes on solid for a few
seconds when the engine
is started. If the light does
not come on then, have it
fixed immediately.
{WARNING:
If the airbag readiness light stays on after the
vehicle is started or comes on while driving, it
means the airbag system might not be working
properly. The airbags in the vehicle might not
inflate in a crash, or they could even inflate
without a crash. To help avoid injury, have the
vehicle serviced right away. If there is a problem with the airbag system, an airbag
Driver Information Center (DIC) message can also
come on. See
DIC Warnings and Messages
on
page 4‑63for more information.
Airbag Off Light
If the vehicle has an airbag on-off switch, it also has a
passenger airbag status indicator located in the
overhead console.
United StatesCanada
When the vehicle is started, the passenger airbag
status indicator will light ON and OFF, or the symbol for
on and off, will light for several seconds as a system
check. Then, after several more seconds, the status
indicator ON or OFF, or either the on or off symbol, will
light to let you know the status of the right front
passenger frontal airbag.
4-32

When the right front passenger airbag is manually
turned off using the airbag on-off switch in the glove
box, the indicator light OFF or the off symbol will come
on and stay on as a reminder that the airbag has been
turned off. This light will go off when the airbag has
been turned on. SeeAirbag Off Switch
on page 2‑82for more information, including important safety
information.
United StatesCanada
{WARNING:
If the right front passenger's airbag is turned off
for a person who is not in a risk group identified
by the national government, that person will not
have the extra protection of an airbag. In a crash,
the airbag will not be able to inflate and help
protect the person sitting there.
Do not turn off the passenger's airbag unless the
person sitting there is in a risk group identified by
the national government. See Airbag Off Switch
on page 2‑82for more on this, including
important safety information.
4-33

{WARNING:
If the airbag readiness light ever comes on and
stays on, it means that something may be wrong
with the airbag system. For example, the right
front passenger airbag could inflate even though
the airbag on-off switch is turned off.
To help avoid injury to yourself or others, have the
vehicle serviced right away. SeeAirbag
Readiness Light
on page 4‑32for more
information, including important safety information.
If the word ON or the on symbol is lit, it means that the
right front passenger frontal airbag is enabled (may
inflate). See Airbag Off Switch
on page 2‑82for more
information, including important safety information.
If, after several seconds, both status indicator lights
remain on, or if there are no lights at all, there may be a
problem with the lights or the airbag on-off switch. See
your dealer for service.
Passenger Airbag Status Indicator
If the vehicle has one of the indicators pictured in the
following illustrations, then the vehicle has a passenger
sensing system for the right front passenger position
unless there is an airbag off switch located in the glove
box. If there is an airbag off switch, the vehicle does not
have a passenger system system. See Airbag Off
Switch on page 2‑82.
The passenger airbag status indicator is on the
overhead console. See Passenger Sensing System
on
page 2‑86for important safety information.
In addition, if the vehicle has a passenger sensing
system for the right front passenger position, the label
on the vehicle's sun visor refers to “ADVANCED
AIRBAGS”.
