Driving and Operating Recommended Transfer Case Settings Driving Conditions Normal Severe Extreme Vehicle in Tow* Transfer Case Settings 2m YES YES YES YES 4m 4n N 9-47 The knob will need to be turned back to the previous transfer case setting in order to see the indicator. Choose among four driving settings: 2 m (Two-Wheel Drive High): This setting is used for driving in most street and highway situations. The front axle is not engaged in two-wheel drive. This setting also provides the best fuel economy. 4 m (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 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. *See Recreational Vehicle Towing on page 10-98 or Towing the Vehicle on page 10-97. Indicator lights show which setting the transfer case is in. Two-Wheel Drive High, Four-Wheel Drive High, and Four-Wheel Drive Low are indicated through the outer ring of the transfer case knob. N (Neutral) is indicated on the face of the knob. The indicator lights will display briefly when you turn on the ignition and one will stay on. If no lights display, take the vehicle to your dealer for service. If the lights display momentarily when the ignition is in ON/RUN, but none stay on, the knob may have been turned while the vehicle was off. To see the indicator, turn the knob to another position so that it matches the actual transfer case setting. An indicator light flashes while shifting the transfer case and remains illuminated when the shift is complete. If the transfer case cannot make a requested shift, it will return to the last chosen setting.
