Active Fuel Management; Engine Exhaust - Chevrolet 2015 Corvette Owner's Manual

Active Fuel Management

This system allows the engine to
operate on either all or half of its
cylinders, depending on the driving
conditions. With a manual gearbox,
the system is only active in Eco
Mode. See Driver Mode Control on
page 9-29.
When less power is required, such
as cruising at a constant vehicle
speed, the system will operate in
the half cylinder mode, allowing the
vehicle to achieve better fuel
economy. When greater power
demands are required, such as
accelerating from a stop, overtaking,
or merging onto a freeway, the
system will maintain full-cylinder
operation.

Engine Exhaust

Warning
Engine exhaust contains carbon
monoxide (CO) which cannot be
seen or smelled. Exposure to CO
can cause unconsciousness and
even death.
Exhaust may enter the vehicle if:
The vehicle idles in areas
with poor ventilation (parking
garages, tunnels, deep snow
that may block underbody
airflow or exhaust pipes).
The exhaust smells or
sounds strange or different.
The exhaust system leaks
due to corrosion or damage.
The vehicle exhaust system
has been modified, damaged,
or improperly repaired.
Driving and Operating
Warning (Continued)
There are holes or openings
in the vehicle body from
damage or aftermarket
modifications that are not
completely sealed.
If unusual fumes are detected or
if it is suspected that exhaust is
coming into the vehicle:
Drive it only with the windows
completely down.
Have the vehicle repaired
immediately.
Never park the vehicle with the
engine running in an enclosed
area such as a garage or a
building that has no fresh air
ventilation.
