Instruments and Controls 5-31
For example, if driving in traffic
and making frequent stops, this
display may read one number,
but if the vehicle is driven on a
freeway, the number may change
even though the same amount
of fuel is in the fuel tank. This is
because different driving conditions
produce different fuel economies.
Generally, freeway driving produces
better fuel economy than city
driving. Fuel range cannot be reset.
Average Economy
Press the trip/fuel button until AVG
ECONOMY displays. This display
shows the approximate average
liters per 100 kilometers (L/100 km)
or miles per gallon (mpg). This
number is calculated based on
the number of L/100 km (mpg)
recorded since the last time this
menu item was reset. To reset
AVG ECONOMY, press and hold
the set/reset button.Fuel Used
Press the trip/fuel button until
FUEL USED displays. This display
shows the number of liters (L) or
gallons (gal) of fuel used since the
last reset of this menu item. To reset
the fuel used information, press and
hold the set/reset button while FUEL
USED is displayed.
Timer
Press the trip/fuel button until
TIMER displays. This display can
be used as a timer.
To start the timer, press the
set/reset button while TIMER is
displayed. The display will show
the amount of time that has passed
since the timer was last reset, not
including time the ignition is off.
Time will continue to be counted
as long as the ignition is on, even
if another display is being shown
on the DIC. The timer will record
up to 99 hours, 59 minutes and
59 seconds (99:59:59) after which
the display will return to zero.To stop the timer, press the set/reset
button briefly while TIMER is
displayed.
To reset the timer to zero, press
and hold the set/reset button while
TIMER is displayed.

the automatic transmission fluid
in either degrees Celsius (°C) or
degrees Fahrenheit (°F).
Instantaneous Economy and
Active Fuel Management™
Indicator
If your vehicle has this display,
press the trip/fuel button until
INST ECON V8 displays. This
display shows the current fuel
economy at a particular moment
and will change frequently as
driving conditions change.

Black plate (36,1)GMC Yukon/Yukon XL Owner Manual - 2011
5-36 Instruments and Controls
The trip odometer has a feature
called the retro-active reset. This
can be used to set the trip odometer
to the number of kilometers (miles)
driven since the ignition was last
turned on. This can be used if the
trip odometer is not reset at the
beginning of the trip.
To use the retro-active reset feature,
press and hold the trip odometer
reset stem for at least four seconds.
The trip odometer will display the
number of kilometers (km) or
miles (mi) driven since the ignition
was last turned on and the vehicle
was moving. Once the vehicle
begins moving, the trip odometer
will accumulate mileage. For
example, if the vehicle was driven
8 km (5 miles) before it is started
again, and then the retro-active
reset feature is activated, the
display will show 8 km (5 miles).
As the vehicle begins moving, the
display will then increase to 8.2 km
(5.1 miles), 8.4 km (5.2 miles), etc.Transmission Temperature
Press the trip odometer reset stem
until TRANS TEMP displays. This
display shows the temperature of
the automatic transmission fluid in
either degrees Celsius (°C) or
degrees Fahrenheit (°F).
Trailer Gain and Output
On vehicles with the Integrated
Trailer Brake Control (ITBC) system,
the trailer brake display appears in
the DIC. Press the trip odometer
reset stem until TRAILER GAIN and
OUTPUT display.
TRAILER GAIN shows the trailer
gain setting. This setting can be
adjusted from 0.0 to 10.0 with
either a trailer connected or
disconnected. To adjust this setting,
see
“Integrated Trailer Brake Control
System” underTowing Equipment
on page 9‑84 for more information. OUTPUT shows the power output
to the trailer anytime a trailer with
electric brakes is connected. Output
is displayed in 0 to 10 bars. Dashes
may appear in the OUTPUT display.
See
“Integrated Trailer Brake
Control System” underTowing
Equipment on page 9‑84 for more
information.
Compass Zone Setting
This display allows for setting the
compass zone. See Compass on
page 5‑6 for more information.
Compass Recalibration
This display allows for calibrating
the compass. See Compass on
page 5‑6 for more information.

Lighting 6-3
When the high beams are on, this
indicator light on the instrument
panel cluster will also be on.
Flash-to-Pass
This feature lets you use the
high-beam headlamps to signal
a driver in front of you that you
want to pass. It works even if the
headlamps are in the automatic
position.
To use it, pull the turn signal lever
toward you, then release it.
If the headlamps are in the
automatic position or on low beam,
the high-beam headlamps will turn
on. They will stay on as long as
you hold the lever toward you.The high-beam indicator on the
instrument panel cluster will come
on. Release the lever to return to
normal operation.
Daytime Running
Lamps (DRL)
Daytime Running Lamps (DRL) can
make it easier for others to see the
front of your vehicle during the day.
Fully functional daytime running
lamps are required on all vehicles
first sold in Canada.
The DRL system comes on when
the following conditions are met:
.The ignition is on.
.The exterior lamps control is
in AUTO.
.The transmission is not in Park.
.The light sensor determines it is
daytime.
When the DRL system is on,
only the DRL lamps are on. The
taillamps, sidemarker, instrument
panel lights, and other lamps will
not be on.
When it begins to get dark, the
automatic headlamp system
switches from DRL to the
headlamps.
To turn off the DRL lamps, turn the
exterior lamps control to the OFF
position and then release. For
vehicles first sold in Canada, the
transmission must be in the P (Park)
position before the DRL lamps can
be turned off.

6-4 Lighting
Automatic Headlamp
System
When it is dark enough outside, the
automatic headlamp system turns
on the headlamps at the normal
brightness, along with the taillamps,
sidemarker, parking lamps, and the
instrument panel lights. The radio
lights will also be dim.
To turn off the automatic headlamp
system, turn the exterior lamps
switch to the off position and then
release it. For vehicles first sold in
Canada, the transmission must be
in the P (Park) position before the
automatic headlamp system can be
turned off.
The vehicle has a light sensor
located on the top of the instrument
panel which regulates when the
automatic headlamps turn on. Do
not cover the sensor, otherwise the
headlamps will come on whenever
the ignition is on.
The system may also turn on the
headlamps when driving through a
parking garage or heavy overcast
weather. This is normal.There is a delay in the transition
between the daytime and nighttime
operation of the Daytime Running
Lamps (DRL) and the automatic
headlamp systems so that driving
under bridges or bright overhead
street lights does not affect the
system. The DRL and automatic
headlamp system are only affected
when the light sensor detects a
change in lighting lasting longer
than the delay.
If the vehicle is started in a dark
garage, the automatic headlamp
system comes on immediately.
Once the vehicle leaves the garage,
it takes approximately one minute
for the automatic headlamp system
to change to DRL if it is bright
enough outside. During that delay,
the instrument panel cluster may not
be as bright as usual. Make sure the
instrument panel brightness control
is in the full bright position. See
Instrument Panel Illumination
Control on page 6‑7.

9-14 Driving and Operating
Exit on the uphill side and stay clear
of the path the vehicle would take if
it rolled downhill. If the vehicle has
a transfer case with a N (Neutral)
position, do not shift the transfer
case to Neutral when you leave the
vehicle. Leave it in some gear.
{WARNING
If the vehicle has the two‐speed
automatic transfer case, shifting
the transfer case to Neutral can
cause your vehicle to roll even if
the transmission is in P (Park).
This is because the Neutral
position on the transfer case
overrides the transmission. You
or someone else could be injured.
If you are going to leave your
vehicle, set the parking brake
and shift the transmission to
P (Park). But, if the vehicle has
a two‐speed automatic transfer
case, do not shift the transfer
case to Neutral.
Driving Downhill
When off-roading takes you
downhill, consider:
.How steep is the downhill? Will
I be able to maintain vehicle
control?
.What is the surface like?
Smooth? Rough? Slippery?
Hard-packed dirt? Gravel?
.Are there hidden surface
obstacles? Ruts? Logs?
Boulders?
.What is at the bottom of the hill?
Is there a hidden creek bank or
even a river bottom with large
rocks?
If you decide you can go down a
hill safely, try to keep the vehicle
headed straight down. Use a low
gear so engine drag can help the
brakes so they do not have to do all
the work. Descend slowly, keeping
the vehicle under control at all
times.
{WARNING
Heavy braking when going down
a hill can cause your brakes to
overheat and fade. This could
cause loss of control and a
serious accident. Apply the
brakes lightly when descending a
hill and use a low gear to keep
vehicle speed under control.
Things not to do when driving down
a hill:
.When driving downhill, avoid
turns that take you across the
incline of the hill. A hill that is not
too steep to drive down might be
too steep to drive across. The
vehicle could roll over.
.Never go downhill with the
transmission in N (Neutral),
called free-wheeling. The brakes
will have to do all the work and
could overheat and fade.
