Running The Vehicle While Parked; Automatic Transmission - Chevrolet Tahoe 2022 Owner's Manual

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
0 215 and
Engine Exhaust 0 216.
If parking on a hill and pulling a trailer, see
Driving Characteristics and Towing Tips
0 273.

Automatic Transmission

The shift switches are on the center stack.
The selected gear position will illuminate red
on the shift switch, while all others will be
displayed in white. If the shift is not
immediate, as in very cold conditions, the
indicator on the shift switch may blink until
it is fully engaged.
The transmission does not operate when the
vehicle is off.
If the vehicle is in ACC/ACCESSORY, the
transmission can be shifted into P (Park).
Driving and Operating
If ENGINE START/STOP is pressed twice while
at a relatively high speed, the engine will
turn off and the transmission will
automatically shift to N (Neutral). Once the
vehicle is stopped, P (Park) can be selected.
P : This position locks the drive wheels. Use
P (Park) when starting the engine to prevent
the vehicle from moving easily.
Warning
It is dangerous to get out of the vehicle
if the transmission is not in P (Park) with
the parking brake set. The vehicle
can roll.
Do not leave the vehicle when the engine
is running. If the engine has been left
running, the vehicle can move suddenly.
You or others could be injured. To be
sure the vehicle will not move, even
when on fairly level ground, always set
the parking brake and place the
transmission into P (Park). See Shifting
Into Park 0 215 and
Driving Characteristics and Towing Tips
0 273.
