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

Four-Wheel-Drive Low will turn Traction Control and
StabiliTrak
®
off. See StabiliTrak
