Engine Exhaust; Running The Vehicle While Parked; Automatic Transmission - Chevrolet Colorado 2024 Owner's Manual

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.
Warning (Continued)
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
0 164 and Engine Exhaust 0 167.
If parking on a hill and pulling a trailer, see
Driving Characteristics and Towing Tips
0 220.

Driving and Operating

Automatic Transmission

If equipped, there is an electronic shift lever
position indicator within the instrument
cluster. This display comes on when the
vehicle is on or in accessory mode.
P : This position locks the drive wheels. Use
P (Park) when starting the engine because
the vehicle cannot move easily. When
parked on a hill, especially when the vehicle
has a heavy load, you might notice an
increase in the effort to shift out of P (Park).
See "Torque Lock" under Shifting Into Park
0 164.
