Shifting Out Of Park; Extended Parking - GMC HUMMER EV 2023 Owner's Manual

Shifting out of Park

This vehicle is equipped with an electric
drive unit. The shift lock release button is
designed to prevent inadvertent shifting out
of P (Park). To shift out of P (Park) the
vehicle must be on, the brake pedal must be
applied, the shift lock release button must
be pressed, and the charge cord must be
unplugged.
Parking the vehicle in extreme cold for
several days without the charge cord
connected may cause the vehicle to not
start. Plug the vehicle in to allow the high
voltage battery to be warmed sufficiently.
To shift out of P (Park):
1. Apply the brake pedal.
2. Press POWER
to start the vehicle.
3. Verify that the vehicle is unplugged and
the vehicle ready light is on.
4. Press the shift lock release button.
5. Move the shift lever to the desired
position.
After releasing the shift lever, it will
return to the center position.
The P indicator will turn white and the gear
indicator on the shift lever will turn red
when the vehicle is no longer in P (Park).
If equipped, the Buckle to Drive feature may
prevent shifting from P (Park). See Buckle To
Drive 0 47.
If the vehicle cannot shift from P (Park), a
Driver Information Center (DIC) message
may be displayed. Check that the vehicle is
on, the vehicle ready light is on, and the
brake pedal is applied when you are
attempting to shift out of P (Park). If all of
these conditions are met but the vehicle will
not shift out of P (Park), see your dealer for
service.
