m
4 (Four-Wheel-Drive High): Use the
Four-Wheel-Drive High position when extra
traction is needed, such as on snowy or icy roads
or in most off-road situations. This setting also
engages the front axle to help drive your vehicle.
This is the best setting to use when plowing snow.
n
4 (Four-Wheel-Drive Low): This setting
also engages the 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.
