CHEVROLET Tahoe - Manual (Page 152)

4 n (Four-Wheel Drive Low): This setting also
engages your front axle and delivers extra
torque. You may never need this setting. It sends
maximum power to all four wheels. You might
choose Four-Wheel Drive Low if you are driving
off-road in deep sand, deep mud, deep snow, and
while climbing or descending steep hills.
StabiliTrak
® will not engage in this mode. See
StabiliTrak ® System on page 363 for more
information.
{ CAUTION:
Shifting the transfer case to NEUTRAL
can cause your vehicle to roll even if the
transmission is in PARK (P). You or
someone else could be seriously injured.
Be sure to set the parking brake before
placing the transfer case in NEUTRAL.
See Parking Brake on page 156.
NEUTRAL (N): Shift the vehicle’s transfer case to
NEUTRAL only when towing your vehicle. See
