Chevrolet 2010 Silverado Hybrid Automobile User Manual


 
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 44
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.
