Page: 127 / 578

Notice: Driving on clean, dry pavement in
four-wheel drive for an extended period of time
can cause premature wear on your vehicle’s
powertrain. Do not drive on clean, dry pavement
in Four-Wheel Drive for extended periods of time.

n
(Four-Wheel-Drive Low): This setting also
engages the front axle and delivers extra torque.
You may never need Four-Wheel-Drive Low. 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. When operating in Four-Wheel
Low, the gear ratio provides additional torque when
compared to Four-Wheel-Drive High. The transmission
gear shift feel is exaggerated.
A parking brake symbol
is located next to the
N (NEUTRAL) symbol
as a reminder to set
the parking brake before
shifting the transfer case
in Neutral.
{
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 2-48 .
N (NEUTRAL): Shift to this setting only when
your vehicle needs to be towed. See Recreational
Vehicle Towing on page 4-50 or Towing Your
Vehicle on page 4-49 .
