CHEVROLET 2009 Silverado - Manual (Page 20)

Starting and Operating Your
Vehicle
Starting the Vehicle
{ CAUTION:
Exiting the vehicle, without first shifting into
P (Park), may cause the vehicle to move, and you
or others can be seriously injured. Because the
vehicle has the Automatic Engine Start/Stop
feature, the vehicle’s engine might seem to be shut
off when you come to a complete stop. However,
once the brake pedal is released, the vehicle can
move. The vehicle’s engine can also restart at
any time.
Shift to P (Park) and turn the ignition to LOCK/OFF,
before exiting the vehicle.
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 Towing a Trailer on page 4-2 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. Some of the vehicle conditions that
allow the engine to stop running and enter the Auto
Stop mode are:
• Ignition switch is in the ON/RUN position.
• The hood is closed.
• The gear selector is in P (Park), N (Neutral) or
D (Drive).
• The hybrid battery is at an acceptable state of
charge.
• The hybrid battery voltage, temperature or power
limits are not exceeded. In very hot conditions,
Auto Stop may be unavailable until the hybrid
battery has cooled.
• The engine is at operating temperature.
If you are on an incline, the hybrid drive motor can help
keep the vehicle from rolling backwards, even if the
engine is in Auto Stop.
With your foot off the brake and the vehicle on level
ground, the hybrid drive motor may cause the vehicle to
roll slowly forward, even when the engine is in Auto Stop.
Keep your foot firmly on the brake pedal until you are
ready for the vehicle to move.
