2010 GMC SIERRA warning light

Parking Brake
Set the parking brake by holding the regular brake
pedal down, then pushing down the parking brake
pedal.If the ignition is on, the brake system warning light will
come on. See
Brake System Warning Light
on
page 4‑39.
Notice: Driving with the parking brake on can
overheat the brake system and cause premature
wear or damage to brake system parts. Make sure
that the parking brake is fully released and the
brake warning light is off before driving.
To release the parking brake, hold the regular brake
pedal down, then push down momentarily on the
parking brake pedal until you feel the pedal release.
Slowly pull your foot up off the park brake pedal. If the
parking brake is not released when you begin to drive,
the brake system warning light will flash and a chime
will sound warning you that the parking brake is still on.
If you are towing a trailer and are parking on a hill, see
Towing a Trailer on page 5‑50.

How the System Works
URPA comes on automatically when the shift lever is
moved into R (Reverse). A single tone sounds to
indicate the system is working.
URPA operates only at speeds less than
5 mph (8 km/h).
An obstacle is indicated by audible beeps. The interval
between the beeps becomes shorter as the vehicle gets
closer to the obstacle. When the distance is less than
30 cm (12 in) the beeps are continuous.
To be detected, objects must be at least 25.4 cm (10 in)
off the ground and below tailgate level. Objects must
also be within 2.5 m (8 ft) from the rear bumper. This
distance may be less during warmer or humid weather.
The system can be
disabled by pressing the
rear park aid disable
button located next to
the radio.
The indicator light will come on and PARK ASSIST OFF
displays on the Driver Information Center (DIC) to
indicate that URPA is off, see DIC Warnings and
Messages on page 4‑65.
Notice: If you use URPA while the tailgate is
lowered, it may not detect an object behind your
vehicle, and you might back into the object and
damage your vehicle. Always verify the tailgate is
closed when using URPA or turn off URPA when
driving with the tailgate lowered.

Rear Vision Camera (RVC)
This vehicle may have a Rear Vision Camera system.
Read this entire section before using it.
{WARNING:
The Rear Vision Camera (RVC) system does not
replace driver vision. RVC does not:
.Detect objects that are outside the camera's
field of view, below the bumper, or underneath
the vehicle.
.Detect children, pedestrians, bicyclists,
or pets.
Do not back the vehicle by only looking at the
RVC screen, or use the screen during longer,
higher speed backing maneuvers or where there
could be cross-traffic. Your judged distances using
the screen will differ from actual distances.
So if you do not use proper care before backing
up, you could hit a vehicle, child, pedestrian,
bicyclist, or pet, resulting in vehicle damage,
injury, or death. Even though the vehicle has the
RVC system, always check carefully before
backing up by checking behind and around the
vehicle.
Vehicles Without Navigation System
The rear vision camera system is designed to help the
driver when backing up by displaying a view of the
area behind the vehicle. When the key is in the
ON/RUN position and the driver shifts the vehicle into
R (Reverse), the video image automatically appears on
the inside rear view mirror. Once the driver shifts out of
R (Reverse), the video image automatically disappears
from the inside rear view mirror.
Turning the Rear Vision Camera System
Off or On
To turn off the rear vision camera system, press and
hold
z, located on the inside rearview mirror, until the
left indicator light turns off. The rear camera vision
display is now disabled.
To turn the rear vision camera system on again, press
and hold
zuntil the left indicator light illuminates.
The rear vision camera system display is now enabled
and the display will appear in the mirror normally.

startled and even lose control. Keep the cruise
control switch off until you want to use cruise
control.
1. Press
T.
2. Get up to the desired speed.

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 gage 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 4‑65.
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/retailer before adding
equipment to the outside of the vehicle.
Warning Lights, Gages, and
Indicators
Warning lights and gages 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 gages 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.
Gages can indicate when there might be or there is a
problem with one of the vehicle's functions. Often gages
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 gages 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.
