Parking Brake - GMC 1996 Suburban Owner's Manual

Shifting from 4LO to 4HI or 2HI
To shift from 4LO to
4HI
or 2HI your vehicle must be
stopped or moving less than
3
mph
(4.8

transmission in NEUTRAL

The preferred method
for shifting out of 4LO is to have your vehicle moving
1 to 2 mph (1.6 to 3.2 k d h ) . Press and release the 4 H I
switch. You must wait for the
4HI
indicator light to stop
flashing and remain illuminated before shifting your
transmission into gear.
If the
4HI
switch is pressed when your vehicle is in
gear and/or moving, the
4HI
indicator light will flash
for 30 seconds
but
not complete the shift unless the
vehicle
is
moving slower than 3 nlph
(4.8
km/h) and
the transmission is in NEUTRAL (N).
