Black plate (4,1)Chevrolet Tahoe and GMC Yukon/Yukon Denali Hybrid - 2011
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.

Driving and Operating 9-3
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. SeeTachometer
on page 5‑4 for more information.
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. Some of the vehicle conditions that
may cause the engine to Auto
Start are:
.The hood is opened.
.The gear selector is in
M (Manual Mode).
.The hybrid battery state of
charge is too low.
.The hybrid battery voltage,
temperature or power limits are
exceeded.
.A remote vehicle start has been
requested.
.The engine is not at operating
temperature.
.Acceleration demands require
the use of the engine.
EV Mode
The vehicle also has an Electric
Vehicle (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.
If increased acceleration is
required, or the vehicle reaches
approximately 40 km/h (30 mph), the
engine will start automatically. The
engine shuts off at speeds below
40 km/h (25 mph) unless the
transmission is in M (Manual Mode)
or Auto Stop is disabled.
During heavy acceleration, both the
engine and hybrid electric motors
supply power. A sensation similar to
a transmission gear change can be
felt as the transmission changes
modes. Engine RPM may remain
above 4,000 RPM for a longer
period during hard acceleration.

10-26 Vehicle Care
If a tire goes flat, avoid further tire
and wheel damage by driving slowly
to a level place. Turn on the hazard
warning flashers.
SeeIf a Tire Goes Flat on
page 10‑22 for other important
safety warnings.
Do not remove any objects that
have penetrated the tire.
1. Remove the tire sealant and compressor kit from its storage
location. See Storing the Tire
Sealant and Compressor Kit on
page 10‑31.
Make sure the on/off button (D)
is in the off (O) position.
2. Unwrap the sealant/air hose (G) and the power plug (C).
3. Place the kit on the ground. Make sure the tire valve stem is
positioned close to the ground
so the hose will reach it.
4. Remove the valve stem cap from the flat tire by turning it
counterclockwise. 5. Attach the sealant/air hose (G)
onto the tire valve stem. Turn it
clockwise until it is tight.
6. Plug the power plug (C) into the accessory power outlet in the
vehicle. Unplug all items from
other accessory power outlets.
See “Power Outlets” in the
owner manual.
If the vehicle has an accessory
power outlet, do not use the
cigarette lighter.
If the vehicle only has a cigarette
lighter, use the cigarette lighter.
Do not pinch the power plug
cord in the door or window.
7. Start the vehicle. The vehicle must be running while using the
air compressor.
8. Press the on/off (D) button to turn the tire sealant and
compressor kit on.
The compressor will inject
sealant and air into the tire. The pressure gauge (E) will
initially show a high pressure
while the compressor pushes the
sealant into the tire. Once the
sealant is completely dispersed
into the tire, the pressure will
quickly drop and start to rise
again as the tire inflates with
air only.
9. Inflate the tire to the recommended inflation pressure
using the pressure gauge (E).
The recommended inflation
pressure can be found on the
Tire and Loading Information
label. See Tire Pressure on
page 10‑17.
The pressure gauge (E) may
read higher than the actual tire
pressure while the compressor is
on. Turn the compressor off to
get an accurate pressure
reading. The compressor may
be turned on/off until the correct
pressure is reached.

Vehicle Care 10-29
7. Attach the air only hose (F) ontothe tire valve stem and press the
lever down to secure it.
8. Plug the power plug (C) into the accessory power outlet in the
vehicle. Unplug all items from
other accessory power outlets.
See “Power Outlets” in the
owner manual.
If the vehicle has an accessory
power outlet, do not use the
cigarette lighter.
If the vehicle only has a cigarette
lighter, use the cigarette lighter.
Do not pinch the power plug
cord in the door or window.
9. Start the vehicle. The vehicle must be running while using the
air compressor. 10. Press the on/off (D) button to
turn the compressor on.
The compressor will inflate the
tire with air only.
11. Inflate the tire to the recommended inflation
pressure using the pressure
gauge (E). The recommended
inflation pressure can be found
on the Tire and Loading
Information label. See Tire
Pressure on page 10‑17.
The pressure gauge (E) may
read higher than the actual tire
pressure while the compressor
is on. Turn the compressor off
to get an accurate reading. The
compressor may be turned on/
off until the correct pressure is
reached. 12. Press the on/off button (D) to
turn the tire sealant and
compressor kit off.
Be careful while handling the
tire sealant and compressor kit
as it could be warm after
usage.
13. Unplug the power plug (C) from the accessory power outlet in
the vehicle.
14. Disconnect the air only hose (C) from the tire valve
stem, by turning it
counterclockwise, and replace
the tire valve stem cap.
15. Replace the air only hose (F) and the power plug (C) back in
its original location.
16. Place the equipment in the original storage location in the
vehicle.
