2010 GMC YUKON HYBRID instrument cluster

Automatic Transfer Case
The transfer case knob is located to the left of the
instrument panel cluster. You can choose among
five driving settings:
2
m(Two-Wheel Drive High):This setting is used for
driving in most street and highway situations.
AUTO (Automatic Four-Wheel Drive) : This setting is
ideal for use when road surface traction conditions are
variable.
4
m(Four-Wheel Drive High): Use the four-wheel high
position when you need extra traction, such as on
snowy or icy roads or in most off-road situations. 4
n(Four-Wheel Drive Low) :
This setting delivers
extra torque. You might choose Four-Wheel Drive Low if
you are driving off-road in deep sand, deep mud, deep
snow, and while climbing or descending steep hills.
N (Neutral) : Shift the vehicle's transfer case to
N (Neutral) only when towing the vehicle. See
Recreational Vehicle Towing or Towing Your Vehicle
in the index of the Owner Manual.
See Four-Wheel Drive on page 3‑10.
Hybrid Features
Hybrid Safety Information
This vehicle has a standard 12-volt battery and a
high-voltage hybrid battery. Only a trained service
technician with the proper knowledge and tools should
inspect, test, or replace the hybrid battery. See your
dealer/retailer if the hybrid battery needs service.
The 12-volt battery cables, in the engine compartment,
are clearly labeled. In emergency situations, first
responders can cut those cables to disable the
high-voltage hybrid battery system.

Automatic Transmission Operation
The vehicle has an electronic shift position indicator
within the instrument panel cluster.
There are several different positions for the shift lever.
See“Range Selection Mode” later in this section.
P (Park) : This position locks the rear wheels. It is the
best position to use when you start the engine because
the vehicle cannot move easily.
When parked on a hill, especially when the vehicle has
a heavy load, you may notice an increase in the effort to
shift out of P (Park). See “Shifting Into P (Park)”in the
Index of vehicle's owner manual for more information.
{WARNING:
It is dangerous to get out of the vehicle if the shift
lever is not fully in P (Park) with the parking brake
firmly set. The vehicle can roll.
Do not leave the vehicle when the engine is
running unless you have to. If you have left the
engine running, the vehicle can move suddenly.
You or others could be injured. To be sure the
vehicle will not move, even when you are on fairly
level ground, always set the parking brake and
move the shift lever to P (Park). See Shifting Into
Park in the Owner Manual. If you are pulling a
trailer, see Towing a Trailer on page 5‑8.
3-6

Four-Wheel Drive
If the vehicle has four-wheel drive, you can send the
engine's driving power to all four wheels for extra
traction. Read the following before using four-wheel
drive.
Notice:Driving on clean, dry pavement in
Four-Wheel-Drive High or Four-Wheel-Drive Low for
an extended period of time may cause premature
wear on your vehicle's powertrain. Do not drive on
clean, dry pavement in Four-Wheel-Drive High or
Four-Wheel-Drive Low for extended periods of time.
While driving on clean dry pavement and during tight
turns, you may experience a vibration in the steering
system.
The vehicle has StabiliTrak
®. Shifting into
Four-Wheel-Drive Low will turn Traction Control and
StabiliTrak
®off. See StabiliTrak®System in the index
of the Owner Manual for more information.
Front Axle
The front axle engages and disengages automatically
when you shift the transfer case. Some delay for the
axle to engage or disengage is normal.
Automatic Transfer Case
The transfer case knob is
located to the left of the
instrument panel cluster.
Use this dial to shift into and out of four-wheel drive.
You can choose among five driving settings:
Indicator lights in the switches show you which setting
you are in. The indicator lights will come on briefly
when you turn on the ignition and the last chosen
setting will stay on. If the lights do not come on, you
should take the vehicle to your dealer/retailer for
service. An indicator light will flash while shifting. It will
stay on when the shift is completed. If for some reason
the transfer case cannot make a requested shift, it will
return to the last chosen setting.

hood is closed, you should have the hood switch
serviced. Failure to service the hood switch properly
can result in an Auto Start condition.
Auto Stops will be disabled when this message is
displayed. 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 4 WHEEL DRIVE
This message may display if a problem occurs with the
four-wheel-drive system. If this message appears, stop
as soon as possible and turn off the vehicle. Make sure
the key is in the LOCK/OFF position for at least
one minute and then restart the vehicle and check for
the message on the DIC display. If the message is still
displayed or appears again when you begin driving,
the four-wheel-drive system needs service. See your
dealer/retailer.
SERVICE BATTERY CHARGING
SYSTEM
If the 12V battery system faults or fails this message will
appear on the DIC. The battery/charging system light
will appear in the instrument panel cluster. See “Battery
Warning Light” in the owner manual Index. Driving with
this message on could drain the battery. Have the
electrical system checked as soon as possible.
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 Warning Light,” and“ABS Brake System
Warning Light” in the owner manual Index.
SERVICE HYBRID SYSTEM
If this message is displayed on the DIC, the vehicle may
continue to operate, but you need to have it serviced as
soon as possible.
SERVICE POWER STEERING
This message displays if a problem has been detected
with the electric power steering. Have your vehicle
serviced by your dealer/retailer immediately.

When to Check
Check your tires once a month or more.
How to Check
Use a good quality pocket-type gage to check tire
pressure. You cannot tell if your tires are properly
inflated simply by looking at them. Radial tires may look
properly inflated even when they're underinflated.
Check the tire's inflation pressure when the tires are
cold. Cold means your vehicle has been sitting for at
least three hours or driven no more than 1 mile (1.6 km).
Remove the valve cap from the tire valve stem. Press
the tire gage firmly onto the valve to get a pressure
measurement. If the cold tire inflation pressure matches
the recommended pressure on the tire and loading
information label, no further adjustment is necessary.
If the pressure is low, add air until you reach the
recommended amount.
If you overfill the tire, release air by pushing on the
metal stem in the center of the tire valve. Recheck the
tire pressure with the tire gage.
Be sure to put the valve caps back on the valve stems.
They help prevent leaks by keeping out dirt and
moisture.
Tire Pressure Monitor Operation
This vehicle may have a Tire Pressure Monitor System
(TPMS). The TPMS is designed to warn the driver when
a low tire pressure condition exists. TPMS sensors are
mounted onto each tire and wheel assembly. The TPMS
sensors monitor the air pressure in the vehicle's tires
and transmit the tire pressure readings to a receiver
located in the vehicle.
When a low tire pressure
condition is detected, the
TPMS will illuminate the
low tire pressure warning
symbol located on the
instrument panel cluster.
At the same time a message to check the pressure
in a specific tire appears on the Driver Information
Center (DIC) display. The low tire pressure warning
light and the DIC warning message come on at
each ignition cycle until the tires are inflated to
the correct inflation pressure. Using the DIC, tire
pressure levels can be viewed by the driver. For
