Range Selection Mode
The Range Selection Mode switch
is located on the shift lever. To
enable the Range Selection feature,
move the column shift lever to the
M (Manual) position. The current
range will appear next to the M. This
is the highest attainable range with
all lower gears accessible. As an example, when 3 (Third) gear is
selected, 1 (First) through 3 (Third)
gears are available.
Press the plus/minus buttons,
located on the steering column shift
lever, to select the desired range of
gears for current driving conditions.
See Automatic Transmission
Operation in the owner manual.
Cruise control can be used while the
vehicle is in Range Selection Mode.
See
Manual Mode on page 9‑9.
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.

Fuel Economy Gauge
United States
CanadaThis gauge shows when the vehicle
is operating at a fuel efficient point.
By modifying driving behavior to
increase the economy time during
driving, fuel mileage will be
improved.
See
Fuel Economy Gauge on
page 5‑6.
Automatic Engine Start/
Stop Feature
Start the engine as you would any
other engine. See “Starting the
Engine” in the owner manual for
more information on starting. The
hybrid system provides very quiet
engine starting. If pulling a trailer
with trailer brakes, see Trailer
Towing on page 9‑16 for more
information.
Auto Stop
The vehicle has an Auto Stop
feature. After a successful engine
start, the engine may turn off and
operate in the Auto Stop mode.
Keep your foot firmly on the brake
pedal until you are ready for the
vehicle to move.
Engine OFF and AUTO STOP
modes are indicated on the
tachometer display. When the
tachometer needle indicates OFF,
the engine is not running and will
remain off until the ignition key is
placed in the START position or a
remote vehicle start is performed.
When the tachometer needle
indicates AUTO STOP, the hybrid
system is on, the engine is not
running, but may Auto Start at any
time without notice. See Tachometer
on page 5‑4 for more information.

1-4 In Brief
A chime will sound if the driver door
is opened while in Auto Stop as a
reminder that the ignition switch is
not in the LOCK/OFF position.
Always turn the ignition switch to
LOCK/OFF and remove the key
from the ignition switch when exiting
the vehicle.
Auto Start
The vehicle also has an Auto Start
feature. The engine will remain off
while in Auto Stop mode until
vehicle conditions require the
engine to run. The near-instant
starting of the engine from Auto
Stop mode is called Auto Start.
EV Mode
The vehicle also has an EV mode
which uses only the electric motor to
move the vehicle. With light
acceleration, the vehicle will drive in
EV mode. EV mode is unavailable
when the vehicle is out of fuel.
For more information on Auto Stop,
Auto Start, and EV Mode, see
Starting the Vehicle on page 9‑2.
Regenerative Braking
Regenerative braking enables the
electric drive motor to operate as a
generator when coasting or braking.
Energy from the moving vehicle
recharges the hybrid battery.
The hydraulic disc brakes work with
the regenerative braking to insure
effective braking.
The braking system is computer
controlled and blends the
regenerative braking with the
conventional hydraulic disc brakes
to meet any requirements for
deceleration. Because the controller
applies the hydraulic brakes through
its high pressure accumulator, you
may occasionally hear the motor
driven pump when it recharges the
system. This is normal. In the event
of a controller problem, the brake
pedal may be harder to push and
the stopping distance may be
longer.
SeeRegenerative Braking on
page 9‑15.
Battery
This vehicle has a standard 12-volt
battery and a high voltage hybrid
battery. When a new standard
12-volt battery is needed, see your
dealer for one that has the
replacement number shown on the
original battery's label. Only a
trained service technician with the
proper knowledge and tools should
inspect, test, or replace the hybrid
battery. See your dealer if the hybrid
battery needs service. See Battery
on page 10‑12.
Service
Never try to do your own service on
hybrid components. You can be
injured and the vehicle can be
damaged if you try to do your own
service work. Service and repair of
these hybrid components should
only be performed by a trained
service technician with the proper
knowledge and tools. See Doing
Your Own Service Work on
page 10‑2.

Tachometer
English Version shown, Metricsimilar When the gas engine is off and the
key is in the ON/RUN position, the
position of the tachometer indicator
shows the state of the vehicle:
.AUTO STOP position indicates
that the vehicle is still able to
move and the engine could
restart, by an Auto Start, at
any time.
.OFF position indicates that the
vehicle is off.
When the engine is on, the
tachometer indicator shows
the engine's revolutions
per minute (rpm).
Fuel Gauge

Black plate (5,1)Chevrolet Tahoe and GMC Yukon/Yukon Denali Hybrid - 2011
Instruments and Controls 5-5
When the ignition is on, the fuel
gauge shows approximately how
much fuel is left in the tank. The
gauge will first indicate E (empty)
before it is out of fuel, but the
vehicle should be refueled as
soon as possible.
An arrow on the fuel gauge
indicates the side of the vehicle the
fuel door is on.Listed are four situations that may
occur with the fuel gauge, none of
these indicate a problem:
.At the gas station, the fuel pump
shuts off before the gauge reads
F (full).
.It takes a little more or less fuel
to fill up than the fuel gauge
indicated. For example, the
gauge may have indicated the
tank was half full, but it actually
took a little more or less than
half the tank's capacity to fill
the tank.
.The gauge moves a little while
turning a corner or speeding up.
.The gauge does not go back to
E (empty) when the ignition is
turned off.

EnglishThis gauge shows displays how
efficiently the vehicle is being
driven.
There are three zones on the drive
efficiency gauge.
Green Zone:
Fuel efficient driving
behavior makes the indicator
display in the green zone on the
gauge.
White Zones: Decreased fuel
efficiency driving behavior makes
the indicator display in the two white
zones. The indicator in the white
zone on the left side of the gauge
indicates decreased fuel efficiency
with a large amount of
decelerations. The indicator in the
white zone on the right side of the
gauge indicates decreased fuel
efficiency with a large amount of
accelerations.

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 vehiclestill 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
Fuel Economy Gauge
on page 5‑6.
See Driver Information Center (DIC)
on page 5‑11 for all brake related
DIC messages.
StabiliTrak®OFF 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. 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.

Engine Oil Pressure Light
{WARNING
Do not keep driving if the oil
pressure is low. The engine can
become so hot that it catches fire.
Someone could be burned. Check
the oil as soon as possible and
have the vehicle serviced.
Notice: Lack of proper engine oil
maintenance can damage the
engine. The repairs would not be
covered by the vehicle warranty.
Always follow the maintenance
schedule for changing engine oil.
This light comes on briefly as a
check it works, when the ignition is
in ON/RUN. If it does not, have the
vehicle serviced.
If the light comes on and stays on, it
means that oil is not flowing through
the engine properly. The vehicle
could be low on oil and might have
some other system problem.
During an AUTO STOP there is zero
oil pressure, but this light will not
come on.
