2009 GMC YUKON HYBRID reset

Storage Areas
Power Outlet Alternating Current
The vehicle may have a power outlet that can be used
to plug in electrical equipment that uses a maximum
limit of 150 watts.
The power outlet is located
in the rear cargo area on
the driver side.
An indicator light on the outlet turns on to show it is in
use. The light comes on when the ignition is in ON/RUN
and equipment requiring less than 150 watts is plugged
into the outlet, and no system fault is detected.The indicator light does not come on when the ignition
is in LOCK/OFF or if no equipment is plugged into
the outlet.
If equipment is connected using more than 150 watts,
or a system fault is detected, a protection circuit shuts
off the power supply and the indicator light turns off.
To reset the circuit, unplug the item and plug it back
in or turn the Retained Accessory Power (RAP) off and
then back on. The power restarts when equipment
using 150 watts or less is plugged into the outlet and a
system fault is not detected.
The power outlet is not designed for the following
electrical equipment and may not work properly if these
items are plugged into the power outlet:
•Equipment with high initial peak wattage such as:
compressor-driven refrigerators and electric
power tools.
•Other equipment requiring an extremely stable
power supply such as: microcomputer-controlled
electric blankets, touch sensor lamps, etc.

Antilock Brake System (ABS)
Warning Light
For vehicles with the
Antilock Brake System
(ABS), this light comes on
briefly when the engine
is in ON/RUN.
That is normal. If the light does not come on then, have
it fixed so it will be ready to warn if there is a problem.
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 still 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.
SeeBrake System Warning Light on page 3-6.
For vehicles with a Driver Information Center (DIC),
seeDIC Warnings and Messages on page 3-12for all
brake related DIC messages.
StabiliTrak®Indicator Light
For vehicles with
StabiliTrak, this warning
light comes on briefly when
the ignition is in ON/RUN.
If it does not, have the vehicle serviced by your
dealer/retailer. If the system is working normally the
indicator light goes off.
When this light flashes, the system is on.
If it stays on while driving, there may be a problem with
the StabiliTrak system and the vehicle may need
service. See the owner manual for more information.

Driver Information Center (DIC)
Trip/Fuel Menu Items
Press the trip/fuel button to display the battery voltage.
For more items see “DIC Operation and Displays” in
the owner manual.
BATTERY VOLTAGE
This display shows the current battery voltage. If the
voltage is in the normal range, the value will display.
For example, the display may read BATTERY
VOLTAGE 13.2 VOLTS. If the voltage is low, the
display will show LOW. If the voltage is high, the display
will show HIGH. Your vehicle’s charging system
regulates voltage based on the state of the battery.
The battery voltage may fluctuate when viewing this
information on the DIC. This is normal. See “Charging
System Light” in the owner manual for more information.
If there is a problem with the battery charging system,
the DIC will display a message. SeeDIC Warnings
and Messages on page 3-12.
INST (Instantaneous) ECONOMY
This display normally shows instantaneous fuel
economy. When the vehicle is in Auto Stop mode
AUTO STOP will be displayed. SeeStarting the
Vehicle on page 2-3for more information. The display
may also show if the vehicle is currently in V4 MODE
or V8 MODE. See “Active Fuel Management” in
the owner manual for more information.
DIC Warnings and Messages
Warning messages are displayed on the DIC to notify
the driver that the status of the vehicle has changed and
that some action may be needed by the driver to
correct the condition. If there is more than one message
that needs to be displayed they will appear one after
another. Some messages may not require immediate
action but you should press the select button or the trip
odometer reset stem on the instrument panel cluster
to acknowledge that you received the message
and clear it from the display. Some messages cannot
be cleared from the display because they are more
urgent; these messages require action before they can
be removed from the DIC display. The following are
the possible messages that can be displayed and some
information about them. For information on other DIC
messages, see “DIC Warnings and Messages” in
the owner manual Index.

If the hybrid battery system faults or fails this message
will appear on the DIC. The engine auto stop feature
will be disabled and the battery/charging system light will
appear in the instrument panel cluster. See “Battery
Warning Light” in the owner manual Index.
Driving with this light on could drain your batteries.
Have the electrical system checked as soon as possible.
Pressing the select button or the trip odometer reset
stem on the instrument panel cluster will acknowledge
this message and clear it from the DIC display.
HOOD OPEN
If the hood is not fully closed or there is a problem
with the hood switch, this message will be displayed.
Close the hood to clear the message. If the HOOD
OPEN message continues to be displayed after
verifying the hood is closed, you should have the hood
switch serviced. Pressing the select button or the
trip odometer reset stem on the instrument panel cluster
will acknowledge this message and clear it from the
DIC display.
When this message is displayed, the auto stop
function will not operate. If the vehicle is in auto stop
mode when this message appears, the engine will
instantly start.
OIL PRESSURE LOW STOP ENGINE
If engine oil pressure is low, this message will be
displayed on the DIC. Stop the vehicle as soon as safely
possible and do not operate it until the cause of the
low oil pressure has been corrected. Check your oil level
as soon as possible and have your vehicle serviced.
See “Engine Oil” in the owner manual Index.
SERVICE BRAKE SYSTEM
This message will be displayed if there is a problem
with the brake system. You will still be able to brake, but
it will be noticeably more difficult. Pull off the road to a
safe location and have your vehicle towed to the nearest
dealer/retailer for service. See “Brakes,” “Brake System

Tire Inspection and Rotation
Tires should be rotated every 5,000 to 8,000 miles
(8 000 to 13 000 km).
Any time you notice unusual wear, rotate your tires
as soon as possible and check wheel alignment.
Also check for damaged tires or wheels. See “When It
Is Time for New Tires” and “Wheel Replacement” in
the Index of the owner manual for more information.
The purpose of regular rotation is to achieve more
uniform wear for all tires on the vehicle. The first rotation
is the most important. See “Scheduled Maintenance”
in the Index of the owner manual.When rotating your tires, always use the correct rotation
pattern shown here.
After the tires have been rotated, adjust the front and
rear inflation pressures as shown on the Tire and
Loading Information label. See “Loading Your Vehicle”
in the Index of the owner manual for an example of
the label and its location on your vehicle.
The Tire Pressure Monitor System (TPMS) sensors will
need to be reset after a tire rotation. See “TPMS
Sensor Identification Codes” under “Tire Pressure
Monitor Operation”.
Make certain that all wheel nuts are properly tightened.
See “Wheel Nut Torque” under “Capacities and
Specifications” in the Index of the owner manual.
