2010 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. See Brake System
Warning Light on page 4‑6.
For vehicles with a Driver Information Center (DIC),
see DIC Warnings and Messages
on page 4‑12for 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.
If the light comes on and stays on while driving, there
could be a problem with the StabiliTrak system and the
vehicle might need service. When this warning light is
on, the StabiliTrak system is off and does not limit
wheel spin.
The light flashes if the system is active and is working
to assist the driver with directional control of the vehicle
in difficult driving conditions.
See the owner manual for more information.

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 high or low,
the display will read HIGH or LOW. 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.
See DIC Warnings and Messages on page 4‑12.
INST ECON (Instantaneous Economy)
This display normally shows instantaneous fuel
economy. When the vehicle is in Auto Stop mode
AUTO STOP or INST ECON = 99 MPG (l/00km) will be
displayed. See Starting the Vehicle
on page 3‑3for
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 can press any of the DIC buttons on the instrument
panel or the trip odometer reset stem to acknowledge
that you received the messages and to clear them from
the display.
Some messages cannot be cleared from the DIC
display because they are more urgent. These
messages require action before they can be cleared.
You should take any messages that appear on the
display seriously and remember that clearing the
messages will only make the messages disappear, not
correct the problem.
For information on other DIC messages, see “DIC
Warnings and Messages” in the owner manual Index.
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

How to Check Automatic Transmission
Fluid
Notice:Too much or too little fluid can damage your
transmission. Too much can mean that some of the
fluid could come out and fall on hot engine parts or
exhaust system parts, starting a fire. Too little fluid
could cause the transmission to overheat. Be sure
to get an accurate reading if you check your
transmission fluid.
Before checking the fluid level, prepare the vehicle as
follows:
1. Start the engine and park the vehicle on a level surface. Keep the engine running.
2. Apply the parking brake and place the shift lever in P (Park).
3. With your foot on the brake pedal, move the shift lever through each gear range, pausing for about
three seconds in each range. Then, move the shift
lever back to P (Park).
4. Allow the engine to idle (500 –800 RPM) for at
least one minute. Slowly release the brake pedal.
5. Keep the engine running and press the Trip/Fuel button or trip odometer reset stem until TRANS
TEMP (Transmission Temperature) displays on the
Driver Information Center (DIC). 6. Using the TRANS TEMP reading, determine and
perform the appropriate check procedure. If the
TRANS TEMP reading is not within the required
temperature ranges, allow the vehicle to cool,
or operate the vehicle until the appropriate
transmission fluid temperature is reached.
Cold Check Procedure
Use this procedure only as a reference to determine if
the transmission has enough fluid to be operated safely
until a hot check procedure can be made. The hot
check procedure is the most accurate method to check
the fluid level. Perform the hot check procedure at the
first opportunity. Use this cold check procedure to check
fluid level when the transmission temperature is
between 24°C and 34°C (75°F and 93°F).
1. Locate the
transmission dipstick at
the rear of the engine
compartment, on the
passenger side of the
vehicle.
See Engine Compartment Overview
on page 6‑4for more information.
2. Pull out the dipstick and wipe it with a clean rag or paper towel.

8. Proceed to the driver side rear tire, and repeat theprocedure in Step 5. The horn sounds two times to
indicate the sensor identification code has been
matched to the driver side rear tire, and the TPMS
sensor matching process is no longer active.
The TIRE LEARNING ACTIVE message on the
DIC display screen goes off.
9. Turn the ignition switch to LOCK/OFF.
10. Set all four tires to the recommended air pressure level as indicated on the Tire and Loading
Information label.
11. Put the valve caps back on the valve stems.
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.
