Chevrolet 2010 Silverado Hybrid Automobile User Manual


 
The vehicle can automatically shift to lower gears as
it adjusts to driving conditions. When 3 (Third) is
selected, 1 (First) through 3 (Third) gears are
automatically shifted by the vehicle, but 4 (Fourth)
cannot be used until it is selected.
The Range Selection Mode controls the vehicle and
engine speed while driving down a hill or towing a
trailer, by allowing you to select a desired range
of gears.
When you move the shift lever into M, the transmission
will default to M4. In this gear range, effective engine
braking occurs at speeds above 45 mph (72 km/h).
Pushing the minus () button on the shift lever reduces
the gear range.
In the M3 gear range, effective engine braking occurs at
speeds above 35 mph (56 km/h).
In the M2 gear range, effective engine braking occurs at
speeds above 25 mph (40 km/h).
In the M1 gear range, effective engine braking occurs at
speeds above 10 mph (16 km/h).
When operating in M (Manual Mode), Auto Stop is
disabled. For better vehicle efficiency, operate the
vehicle in D (Drive) not M (Manual Mode).
Cruise control can be used while using the Range
Selection Mode.
Engine Coolant Heater
The engine coolant heater can provide easier starting
and better fuel economy during engine warm-up in cold
weather conditions at or below 18°C (0°F). Vehicles
with an engine heater should be plugged in at least
four hours before starting. An internal thermostat in
the plug-end of the cord may exist which will prevent
engine coolant heater operation at temperatures
above 18°C (0°F).
