GMC Terrain: Driving and Operating / Engine Exhaust
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 tail
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.
- 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.
Running the Vehicle While Parked
It is better not to park with the
engine running.
If the vehicle is left with the engine
running, follow the proper steps to
be sure the vehicle will not move.
See Shifting Into Park and
Engine Exhaust.
If parking on a hill and pulling a
trailer, see Driving Characteristics
and Towing Tips.

The Diesel Particulate Filter (DPF)
system filters soot particles out of
the exhaust gases. The DPF is
under the vehicle in the exhaust
system.
Depending on a number of factors
monitored by the engine computer,
the DPF will need to be cleaned of
accumulated solids...
