Pontiac 2010 Vibe - Manual (Page 157)

Evaporation Pump
The vehicle is equipped with
a vacuum pump for the fuel
evaporation system. This pump
performs a fuel evaporation leakage
test approximately five hours
after the engine is turned off.
You may hear a sound coming
from underneath the rear cargo
compartment for several minutes.
The noise is normal and does not
signify a malfunction. See your
dealer/retailer with any questions.
Parking Over Things
That Burn
{ CAUTION
Things that can burn could touch
hot exhaust parts under the
vehicle and ignite. Do not park
over papers, leaves, dry grass,
or other things that can burn.
Engine Exhaust
{ CAUTION
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 tail pipes).
• The exhaust smells or
sounds strange or different.
• The exhaust system leaks
due to corrosion or damage.
(Continued)
CAUTION (Continued)
• The vehicle’s exhaust system
has been modified, damaged
or improperly repaired.
• There are holes or openings
in the vehicle body from
damage or after-market
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.
