other engine. See Starting the Enginein 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 916 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 54 for more information.

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 92.

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.
See Regenerative Braking on page 915.

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 1012.

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 102.

Power Outlets

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 comes on when in use. The ignition must be in ON/RUN and equipment requiring less than 150 watts is plugged into the outlet, and no system fault is detected.
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 and may not work properly if the following are plugged in:
.
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.

Metric
Black plate (7,1)
Chevrolet Tahoe and GMC Yukon/Yukon Denali Hybrid - 2011
Instruments and Controls 5-7
English
The oil pressure gauge shows the engine oil pressure in psi (pounds per square inch) when the engine is running. Canadian vehicles indicate pressure in kPa (kilopascals).
Oil pressure should be 200 to 550 kPa (29 to 80 psi). In certain situations, such as long extended idles on hot days, it could read as low as 105 kPa (15 psi) and still be considered normal.
A reading in the low pressure zone may be caused by a dangerously low oil level or some other problem causing low oil pressure. Check the oil as soon as possible.
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.
AUTO STOP
When the engine goes into Automatic Engine Stop, the oil pressure gauge drops to zero when the tachometer is at the AUTO STOP position. This is normal and oil pressure returns to the normal operating range once the engine starts.
See Starting the Vehicle on page 92 for more information.
AUTO STOP displays in the Driver Information Center (DIC) when the vehicle speed is zero. See Driver

Electric Air Conditioning Compressor
This hybrid vehicle has an electrically powered air conditioning compressor. This allows for continuous air conditioning operation and passenger comfort, even while the hybrid engine cycles on and off.
When operating the climate control system, select the AUTO mode and the desired temperature setting. The climate control system automatically adjusts the fan speed and airflow direction. The climate control system continues to adjust the climate control settings chosen for best use of electrical power.
At mild temperatures, select a warmer air conditioner temperature or turn the air conditioner off to get maximum fuel economy. Continuous air conditioner use can cause the vehicle to Auto Start more frequently. During hot weather, driving with the windows closed and the air conditioner set to Auto mode, will result in better Hybrid system performance.
Some noise may be heard occasionally from the compressor, especially when air conditioning use is high and the engine has turned off.
